4.2 SYSTEM UPGRADE

4.2.1 Introduction to System Upgrade

The C8000 OLT device supports the upgrading of system software and board software. The C8000 system consists of three types of boards, SCU, LPU and SLU, of which, all other boards have the pure software with the exception of SLU, and their upgrade can be realized by the command lines. The upgrade can be divided into the following three steps: Firstly, download the bin file to be downloaded into the ramdisk of the SCU; secondly, update the upgrading file in the ram disk of the main SCU to the FLASH as the destination board; and thirdly, restart the destination board to see whether the upgrade is successful. Note: Before the downloading, ensure the C8000 management channel is connected with FTP server, use ping command for diagnostics and inspection. In downloading, ensure the ftp service at the server side is accessible, the user name and the password are correct and the destination file exists.

For the C8000 OLT devices, the different boards have different types of software, see the following for details:

4.4.2 Introduction to FTP

FTP protocol, as the application layer protocol in TCP/IP protocol suite, is mainly for providing file transfer between hosts. The FTP protocol is realized based on the corresponding file system. The C8000 supports FTP Client/Server services, after the connection with the C8000 device by the terminal emulation program or Telnet program on the host is established, enter the ftp command to establish the connection with the remote FTP Server and access to the files on the remote server.

4.4.3 Introduction to Telnet

Telnet protocol is one of the members of TCP/IP protocol suite and the standard protocol for remote login service of Internet. The application of the Telnet protocol can change the computer used by the local user into the terminal of the remote host


36

system. The C8000 supports the Telnet service, after the connection with the C8000 device by the terminal emulation program or Telnet program on the host is established, enter the telnet command to log into the remote host system, which provides the user with convenience.

4.4.4 Introduction to Ping

Ping is a computer network tool for measuring whether the special host can reach by IP. The C8000 supports Ping diagnostic commands. Enter the ping command under the enable view of the command line to check whether the host of special IP addresses can be reached by IP.

5.3 Slot Board Management

5.3.1 Introduction to Slot Management

The C8000 system has 14 board slot areas:

Where No.7 and No.8 are the slots for SCU boards. Note: No.7 and No.8 slots must be inserted into the SCU board of the same type, or SCU-A, or SCU-B. The situation that one in SCU-A and the other in SCU-B is not allowed;

1-6 slots and 9-14 slots are the slots for service board

LPU can be inserted into any a slot among 1-6 or 9-14 slots

SLU can be inserted into No.6 or No.9

Set the board first before implementing other system configuration, with the exception of the automatic loading of the main SCU, the type of other board must be manually set. Now there are five kinds of boards, SCU-A, SCU-B, LPU4, LPU2P and SLU.

The slot management function of the C8000 supports the display of slot information, if no slot parameters are specified, the basic information of all 14 slots will be displayed, including the type of the excepted board, the type of the board actually inserted and the status of the board, etc. If show board-info command is used, the information, the hardware serial number, the MCU version, the led status, temperature and BSP version information, the version information of the applications in flash, the version information of the applications in running, total size of flash, the remaining space of flash, the total size of ramdisk, the remaining space of ramdisk, the version information of the PON card firmware, the DBA algorithm of PON card, the occupancy rate of current CPU, the total size of RAM, the remaining space of RAM, etc.

5.4 Active/Standby Changeover Management

5.4.1 Introduction to Active/Standby Changeover

The C8000 supports the active/standby changeover function of SCU, by default, the SCU of No.7 slot is for the active purpose and the SCU of No.8 slot is for the standby purpose. When the SCU for the active purpose is reset or pulled out or subject to the forced changeover, the standby SCU will become the active SCU, and the original active SCU will automatically reset to ensure that it becomes the new standby board after the startup.


42

Since the data between active and standby SCUs can realize the real-time synchronization, the new active and standby SCUs after the changeover are fully consistent with the originally active and standby SCUs, and the seamless switching in communications with other service boards and network management can be realized.

C8000 can complete the active and standby changeover in the following cases:

Soft reset of SCU for active purpose

Hard reset of SCU for active purpose

SCU for active purpose is pulled out

Forced changeover by network management or command line

5.4.2 Forced Active/Standby Changeover

6 VLAN CONFIGURATION MANAGEMENT

6.1 VLAN Configuration Management

6.1.1 Introduction to VLAN

6.1.1.1 About VLAN

The traditional Ethernet is a planar network; all hosts in the network are connected with each other by HUB or switching equipment and all hosts are in the same broadcast domain. The HUB is a physical-layer device and has no switching function; the packet received will be transmitted to all ports; the switching equipment is a link-layer device and has the capacity of transmitting in accordance with the MAC address of the packet, but when the switching equipment receives the broadcast packet or the unknown unicast packet (The destination MAC address of the packet is not in the MAC address table of the switching equipment), the switching equipment also transmits the packet to all ports except the port sending the packet.

In the above case, the host in the network will receive large number of packets not for the host, wasting a lot of bandwidth resources and causing serious security risks.

The traditional method for isolating the broadcast domain is to use the router, however, the router has the shortcomings of higher cost and fewer ports, and the router cannot divide the refined network, either.

To address the problem that the Ethernet switching equipment cannot restrict the broadcast in LAN, the VLAN technology (Virtual Local Area Network) emerges as the times require.

The VLAN divides a physical LAN into multiple logical LANs, and each VLAN is a broadcast domain. The communication between hosts within a VLAN is the same to that in the LAN, and direct communication between hosts of different VLANs is not allowed.

The members of VLAN are free from the restriction of physical location. A VLAN can be within a switch, in different switching equipment or in different routers. The computers within the same VLAN can be placed in different physical spaces, that is, such computers can also be from different physical network. See Figure 6-1.


44

Figure 6-1 VLAN classification

6.1.1.2 VLAN Principle

To ensure the network device can distinguish the packets of different VLANs, the identified VLAN filed must be added to the packet. Because the switching equipment uses the second layer for working (The function of the third layer is not discussed here), only the data link layer encapsulation of the packet can be identified. Therefore, the filed tag must be added to the data link layer encapsulation.

In 1999, IEEE released the draft IEEE 802.1Q protocol for standardizing the VLAN realization program, that is to say, the protocol standardizes the structure of the packet with VLAN tag.

The traditional Ethernet data frame encapsulates the type filed of upper-layer protocol after the destination MAC address and source MAC address field. See Figure 6-2.

Figure 6-2 Data Frame Format of Traditional Ethernet

Where, DA is the destination MAC address; SA is the source MAC address; Type is the protocol type of the packet. Generally, the field value in the Ethernet data frame is 0x0800.


45

IEEE 802.1Q protocol regulates that 4-byte VLAN Tag is encapsulated after the destination MAC address and the source MAC address to identify VLAN-related information. See Figure 6-3.

DA SA Type DATATPID Priority CFI VLAN ID

VLAN Tag

Figure 6-3 802.1Q Data Frame Format

VLAN Tag contains four fields, namely, TPID, Priority, CFI, VLAN ID, with the total length of 4 bytes.

TPID indicates that the data frame has the VLAN Tag, the length is 16bit and the default value is 0x8100.

Priority indicates the priority of 802.1P with the length of 3bit, See section 15.2.1"Configuring OLT QoS" for the specific uses.

CFI field identifies whether the MAC address is encapsulated in a standard format in different transmission medium. No detailed description is made here. The length is 1bit.

VLAN ID identifies the VLAN that the packet belongs to. The length is 12bit and the range is 0～4095. Because 0 and 4095 are not used generally, the range of VLAN ID is 1～4094.

6.1.1.3 Introduction to Common and Flexible QinQ

QinQ, also known as VLAN Stacking, is the technology to encapsulate the CVLAN Tag of the user network to the network of service provider or the SVLAN Tag of metropolitan area network, so as to make the packet with layer 2 tags cross the backbone network of service provider and transmit in accordance with the VLAN tag of the outer layer in the public network and shield the CVLAN Tag of user network. The technology not only distinguishes data streams, but also allows the user VLAN tag to be repeatedly used and uses only the outer-layer VLAN tag in the public network due to the transparent transmission of the VLAN tag of user network. See Figure 6-4 for the difference between 802.1Q data frame format and the data frame format with layer 2 tag.


46

Figure 6-4 Difference between 802.1Q Data Frame Format and QinQ Data Frame Format

QinQ at the beginning was generated for expanding VLAN capacity and increased the 802.1Q tag based on the original 802.1Q packet, expanding the VLAN capacity to 4094 * 4094.

With the development of Metro Ethernet and the requirements of operators on refinement operation, the layer 2 tag of QinQ can also be used as follows: the inner and outer tags of QinQ can represent different information, for example, the inner CVLAN Tag can be used for distinguishing users and the outer SVLAN Tag can be used for representing service.

There are two ways to encapsulate the outer VLAN tag, one of which is the common QinQ encapsulation, that is, for the port-based outer tag, and all user data of the port must be encapsulated with the same common VLAN tag, however, the method has many restrictions in application, the other of which is the flexible QinQ encapsulation method, the method allows the flow classification of user data in accordance with certain characteristics and then encapsulates different outer VLAN tags to different classifications. The device of our company implements the flow classification by ACL and in accordance with user’s VLAN TAG, MAC address, IP protocol, source address, destination address, application port number and other information, thus providing different outer VLAN tags to the flows of different types and realizing the support to the flexible QinQ (the function has close relations with the type of hardware chip).

802.1ad standard supplements the above ways based on 802.1Q. IEEE 802.1ad (QinQ) standard describes the mode for the Ethernet to realize S+C and to expand the capacity of VLAN. 802.1ad describes the two kinds of interfaces: Port-based service interface and C-tagged service interface, of which, the Port-based mode is to provide the uniform outer Q (common QinQ) to a port while the client-based mode is to provide the different outer


47

Qs (flexible QinQ) in accordance with different user tags. For more information, refer to relevant standards.

6.1.2 OLT port-based VLAN

The OLT port of the OpticalLink C8000 includes the service network interface on the SCU and the PON port on the LPU. The OLT port-based VLAN is to classify the OLT ports on the device to different VLANs to realize the isolation between users and the division of virtual working groups.

6.1.2.1 Introduction to OLT Port Types under Different VLAN Modes

Two models of global support: 802.1ad disable and 802.1ad enable, namely, the model disabling the double-TAG and the model enabling the double-TAG.

802.1ad disable (Double-Tag Disable), all ports work under the hybrid model, support the typical 802.1Q-based (equivalent to CVLAN-based) Hybrid model, in the model, only the CVLAN is involved into the exchange.

In enabling the 802.1ad (Double-Tag Enable), the port can be divided into the transparent port and the Hybrid port, supporting the typical transparent applications, supporting the translate applications (1:1) and supporting the QinQ applications. Hybrid port supports the typical SVLAN-based hybrid applications. In the model, only the SVLAN is involved into the exchange.

6.1.2.1.1 802.1Q-based Hybrid Port VLAN

When setting the global model to be 802.1Q, the ports of the OLT device can only be configured as the Hybrid type.

Hybrid type: the port belonging to multiple VLANs can receive and send the packets of multiple VLANs, The hybrid type can connect the C8000 and the switches, routers or PC of servers and can connect the ONU. All default OLT ports are in the hybrid type.

In the mode, the methods for processing all data packets passing through the port of the type are as follows:

Table 6-1 Processing the Ingress and Egress Packets in the Hybrid Port


48

Processing the Ingress Packets Processing the Egress Packets

Packet with Tag Received Packet without Tag Received If the port is in the VLAN

specified by the tag carried by the packet, then transmit the packet and determine to strip the tag or not in accordance with the configuration of the exit manner.

If the port is not in the VLAN specified by the tag carried by the packet, discard the packet

If the port is in the VLAN specified by PVID, provide the default Tag to the packet, and then transmit the packet

If the port is not in the VLAN specified by the PVID, discard the packet

If the port is in the VLAN specified by the tag carried by the packet, transmit the packet

If the port is not in the VLAN specified by the tag carried by the packet, discard the packet

6.1.2.1.2 Hybrid Port VLAN-based on 802.1ad

After activating the Double-Tag Enable, the port can be set as the transparent port (known as UNI port or Customer port), or as the Hybrid port (also known as SNI port or NNI port or Provider port).

The 802.1ad-based hybrid port can identify the untagged packets, single-tag (ST) package and double-tag (DT) packet. Different from the transparent port under the 802.1ad, the hybrid port will inspect the two TL domains and decides which packet it belongs. The specific judgment of ingress is as shown in Table 6-2:

Table 6-2 Provider Port Packet Decision Table

First TL Domain Second TL Domain Packet Type

OUTER_TPID INNER_TPID DT

OUTER_TPID None ST

INNER_TPID None customer-tagged

None None untagged

Ingress processing flow is as follows:


49

For the untagged packets, the processing method is the same to the normal port and the TPID with the tag is Port OUTER_TPID. For the customer-tagged packets, the processing method is the same to that of the untagged packets. For the ST packet, no processing is made, the direct entering to the VLAN lookup link is allowed. For the DT packet, no processing is made, the direct entering to the VLAN lookup link is allowed. The VLAN lookup link is the one with the VLAN member table established in accordance with the OLT device and the data packet forwarded in accordance with the situation that the port adds into the VLAN. Egress processing flow is as follows: The egress processing flow of the 802.1ad-based hybrid port is similar to that of the 802.1Q-based hybrid port with the differences in the SVLAN Tag rather than Q-Tag and the marking of outer_tpid of the port to the exit data stream.

6.1.2.1.3 802.1ad-based Transparent Port VLAN

After activating the Double-Tag Enable, the port can be set as the transparent port (known as UNI port or Customer port), or as the Hybrid port (also known as SNI port or NNI port or Provider port).

The transparent subnet mask ort ingress processing is as follows:

It needs to judge whether the tpid with the tag of the data packet is equivalent to the inner_tpid of the port.

If the ordinary Ethernet packets without tag or the field is not equivalent to the inner_tpid, the port judge the data packet as the untagged data packet and mark with the pvid, prio, and outer_tpid of the port, and then forward such data packet.

If the tpid of the tag of the data packet is equivalent to the inner_tpid of the port:

Then it needs to judge the vid field with the tag of the data packet is equal to 0, if equal to 0, then the data packet is the prio-tagged packet and is marked with the pvid and outer_tpid of the port, but the original prio of the data packet is still used and then forwarded;

If the vid field with the tag of the data packet is not equal to 0, then it can judge the data packet to be the customer-tagged packet, and then it needs to check the VLAN


50

translation table of the port, only with the CVLAN in the translation table, the QinQ (Add SVLAN beside CVLAN) or translation (Replace CVLAN bye SVLAN) can be made, and then all packets outside the table can be provided with outertpid and PVID, as well as default priority (With the exception of pri-tagged packets, the rest adopt the original priority).

The transparent port egress processing flow is as follows:

The SVLAN will be stripped at the egress direction and the search of the corresponding CVLAN can be made by the SVLAN index at the egress direction, the CVLAN will replace the CVLAN of the original packet. (Note: the translation table at the egress direction can be enabled or disabled).

Note: the port of the type can only send and receive untagged (all ones with the tpid not equal to inner tpid, even the tpid is the outertpid), pri-tagged or customer-tagged packets.

6.1.2.2 Adding the Port to the Designated VLAN

The user can add the OLT port into the designated VLAN. After the implementation of the configuration, the OLT port can transmit the packet of the designated VLAN, thus realizing the interflow between the VLAN of the device of the terminal and the same VLAN of the switching equipment on the terminal connected.

When adding the port to the VLAN, specify the exit manner of the terminal on the VLAN, that is, whether it needs to strip the tag when the port is sending the packet of the VLAN. Tagged indicates not to strip the tag and untagged indicates to strip the tag.

Note：

Hybrid Application: in accordance with network requirements, the port can be added into more than one VLAN.

Transparent transmission application: add to the VLAN specified by the port PVID (ie, the default VLAN ID) and set the exit mode into untagged mode.

Translation Application: add the port connecting the user network and the network of service provider to the VLAN (s) appointed by CVLAN (s) or SVLAN (s) and set the exit manner into tagged mode.

QinQ Application: add the port connecting the user network to the VLAN (s) appointed by SVLAN (s) and set the exit manner into untagged mode; and set the port connecting the network of service provider to the hybrid port and add to the


51

VLAN (s) appointed by SVLAN (s) and set the exit manner into tagged mode.

In addition, the translation application needs to configure the VLAN translation table for the translation of CVLAN(s)->SVLAN(s) and SVLAN(s)->CVLAN(s); the QinQ application needs to configure the VLAN nested table and add SVLAN to the outer layer of CVLAN (s). See "6.2.5 VLAN Transparent Application", "6.2.6 VLAN Translate Application" and "6.2.7VLAN QinQ Application" for the specific configuration

Note:

Add translation port or qinq port to VLAN; in configuring the VLAN translation table of the former and the VLAN nested table of the latter, note: do operate in accordance with the above description, or the packet will be discarded.

6.1.2.3 Configuring the Default VLAN of the Port

The layer 2 transmission of the C8000 depends on VLAN Tag and MAC address (SA & DA). After the packet without VLAN Tag enters to the C8000, the system will provide a default VLAN Tag to the packet, including the default VLAN ID (PVID) and the default priority.

Note:

Hybrid application: the hybrid application can belong to multiple VLANs while the default VLAN ID needs to be specified and 1 by default. It is recommended to set the default VLAN ID of the Hybrid port at the C80000 terminal the same to the default VLAN ID of the Hybrid port of the device connected,

6.1.3 ONU Port-based VLAN

6.1.3.1 Type of ONU Port-based VLAN

The ONU released along with the C8000 supports the following three ONU port-based VLANs

Transparent type: applicable to the occasion when the VLAN Tag generated by the home gateway and the switch of the client that is provided and managed by the


52

service provider is trustworthy. The ONU port does not process the uplink Ethernet frames (No matter whether the Ethernet frame is provided with VLAN TAG) and forwards them in a transparent manner, and also forwards the downlink Ethernet frames in a transparent manner.

Tag Type: applicable to the occasion when the VLAN tag generated by the home gateway or switch of the client cannot be trusted. To realize the unified management and control on the VLAN of the service into the network, a network VLAN Tag is required.

Translation type: the ONU port translates the VLAN TAG provided by the user (the VID may not be used exclusively, and the VID may be used by other users in the same system) into the unique network VLAN Tag.

Note:

The translation port of ONU has only one VLAN Translation(UniVlan-> CniVlan) table, applicable to the uplink service and the downlink service, the only difference is the direciton, that is, the VLAN Tag of the former is checked at the positive direction as the UniVlan while the VLAN Tag of the latter is checked at the opposite direction as the CniVlan.

6.1.3.2 Packet processing for ONU Port

After the normal registration of ONU, the processing modes on the uplink and downlink service data by the three types of ONU ports are different, see the following table for details.

Table 6-2 Processing the Uplink and Downlink Services for ONU Transparent Port

Direction With or without VLAN Tag Processing

6.2.5 VLAN Transparent Application

Transparent Application: the port receives and sends any packets, regardless of whether the VLAN Tag is provided or not, what kind of VLAN Tag it is, that is the transparent transmission of packet.

VLAN-VPN is a simple and flexible, two-layer VPN tunnel technology. It is to encapsulate the outer-layer VLAN tag for the private network packet of the users by the operator’s access terminal, so as to ensure the packet carries two-layer VLAN tag when it passes through the backbone network (Public Network) of the operator. In the public network, the packet can be transmitted in accordance with the out-layer VLAN Tag (or VLAN Tag of the public network), then the VLAN Tag of the user's private network is transmitted as the data in the packet.

Effects: a. Completely transparent transmission, ingress/egress from the transparent port and egress/ ingress from the hybrid port, that is, realize the ingress/egress of any packet in the original state. b. VLAN VPN, egress/ingress from transparent port, egress/ingress from hybrid port and the egress/ingress of any packet in the original form (The svlan tag is not stripped in the hybrid port).

When the global switch is in the 802.1ad enable state, set PON port to work in the transparent mode and the service network interface to work in the hybird mode (based on 802.1ad). For the hybrid port, the outer-tpid, PVID, default Priority, VLAN member table (global) and VLAN untagged bitmap are configurable. For transparent port, the outer-tpid, PVID, default Priority, VLAN member table (global) and VLAN untagged bitmap are configurable.

The configuration must be made by default, the application, due to the absence of the ingress VLAN translation table, all packets must allow the transparent transmission. If some of the packets cannot be subject to the transparent transmission (CVLAN adds to SVLAN or CVLAN changes to SVLAN), the ingress VLAN translation table can be configured, in case of 1:1 VLAN translation, it needs to automatically configure the egress VLAN translation table reversely based on the ingress VLAN translation table. In case of the VLAN-based VPN (with the exit of SVLAN, no stripped), then the exit hybrid port can be provided with the tag. Note: the ports of both sides belong to the same SVLAN.

Note:

The transparent port must be added to the VLAN corresponding to the default VLAN.

6.2.5.2 VLAN Transparent Transmission Configuration Example


Realize the transparent transmission of packet between PON port 3/1 and Service Network Interface 9/1. The service network interface of hybrid type exits in the VLAN of the PON port pvid by the untagged mode; the PON port in the transparent mode is not configured with any forwarding entries, even when the forwarding entries are configured, if it wants to realize the transparent transmission of packets, ensuring the packet not in the forwarding entries, that is to say, the packet can be directly forwarded in the manner when the packet is transmitted. For the downlink direction, when the packet passes through the unlink hybrid, the SVLAN will be marked with and when passing through the PON port transparent, the outer SVLAN will be stripped (The transparent transmission of the downlink direction will strip the outer-layer SVLAN and the inner-layer CVLAN is left, if the data packets are with only one-layer TAG, after they pass through the uplink hybrid and PON port transparent, the data packets without TAG cannot be received).

Create VLAN 200

PON Port Configuration: 802.1ad transparent mode, pvid 200, adding VLAN 200 in the untagged;

Service Network Interface Configuration: 802.1ad hybrid mode, pvid 1, adding VLAN 200 in the untagged mode.

[Note] In the above networking, if the PON port pvid is 1, the creation of any VLAN is not needed(For the Service Network Interface and the PON port, adding to any other VLANs is not needed, because they are in the default VLAN 1.)

6.2.6 VLAN Translate Application

Translation Application: applicable to the occasion when the Tag provided by the user network cannot be trusted by the network of service provider on the premise that when one side of the C8000 is connected with the user network and the other side is connected with the network of service provider. The port connecting the user network translates the


67

tag of the user network in the uplink data into the VLAN Tag trusted by the network of service provider or the port connecting the network of service provider translates the VLAN Tag in the downlink data into the tag of user network.

When the global switch is in the 802.1ad enable state, set PON port to work in the transparent mode and the service network interface to work in the hybird mode (based on 802.1ad). For the hybrid port, the outer-tpid, PVID, default Priority, VLAN member table (global) and VLAN untagged bitmap are configurable. For transparent port, the outer-tpid, PVID, default Priority, VLAN member table (global), VLAN untagged bitmap and VLAN translate mode are configurable. Note: the ports of both sides belong to the same SVLAN.

1：1 VLAN Translation

Effects: ingress from the transparent port and egress from the hybrid port; the different CVLANs in the ingress VLAN translation table at the uplink direction can be translated into the different SVLANs in accordance with the items of the translation table. The different CVLANs in the egress vlan translation table at the downlink direction can be translated into the required CVLAN by the application of the SVLAN index and in accordance with the items of the translation table. The original priority can be modified or retained.

Set the transparent port to 1:1 translation, and add the mapping table to be translated into the ingress VLAN translation table, the original priority can be modified or retained. Automatically add the corresponding ingress reverse mapping table into the background egress VLAN translation table and apply the processing strategy of the same priority.

6.2.6.1 VLAN Translation Configuration

The translation port is used for realizing the translation between the tag of user’s network and the tag of the network of service providers.

6.2.6.2 VLAN Translation Configuration Example


Create VLAN 100, 2000, VLAN 10, 200, of which, the VLAN 10, 200 can be used as the CVLAN Tag of the user network; and the VLAN 100, 2000 can be used as the SVLAN Tag of the network of service provider.

In the uplink, translate the PON port3/1 from CVLAN 10 to SVLAN 100 and change the priority to 1, and in the corresponding downlink, translate from SVLAN 100 to CVLAN 10 in the service network interface 9/1.

In the uplink, translate the PON port3/1 from CVLAN 200 to SVLAN 2000 and


69

remain the original priority, and in the corresponding downlink, translate from the SVLAN 2000 to CVLAN 2000 in the service network interface 9/1.

[Note] The service network interface and the PON port must be added into the SVLAN, if all are added into the SVLAN in the tagged mode, the packets with tags can only be received at the downlink and uplink directions; if the uplink is provided with the tagged packet and the downlink is provided with the untagged packet, the packets without tags can only be received at the downlink direction and the packets without tags can only be received at the uplink direction; if the uplink is provided with the untagged packets and the downlink is provided with the tagged packets, the packets without tags can only be received at the uplink direction and the packets without tags can only be received at the downlink direction.

6.2.7 VLAN QinQ Application

QinQ type: applicable to the occasion when the network of service provider uses the SVLAN Tag to differentiate services and the user network uses the CVLAN Tag to differentiate users on the premise that that one side of the C8000 is connected with user network and the other side is connected with network of service provider. At that time, the port connecting the user network needs to be set into the transparent mode and configure the nested table, for the unlink data packet, add the SVLAN tag of the network of service provider to the outer layer of the CVLAN Tag of user network; for the downlink packet, strip the SVLAN Tag of the outer layer and then forward to the user network.

When the global switch is in the 802.1ad enable state, set PON port to work in the transparent mode and the service network interface to work in the hybird mode (based on 802.1ad). For the hybrid port, the outer-tpid, PVID, default Priority, VLAN member table (global) and VLAN untagged bitmap are configurable. For transparent port, the outer-tpid, PVID, default Priority, VLAN member table (global) and VLAN untagged bitmap are configurable. More attention must be paid to the above default configuration and the configuration of the VLAN translation table. To meet the requirements of the application, it needs to not to strip the VLAN tag of the SVLAN at the hybrid port, and it needs to strip the SVLAN(un-tag) at the opposite transparent port. Note: the ports of both sides belong to the same SVLAN.

Effects: ingress from the transparent port and egress from the hybrid port; in the ingress VLAN translation table, the different CVLANs can add different SVLANs in accordance with the items of the translation table. The priority can modify or use the default priority of the port.

6.2.7.1 VLAN Stacking Configuration

On PON port 3/1, for the uplink data, add the SVLAN 2 to the outer layer of the CVLAN 200 and translate the priority to 5; for the downlink data, strip the SVLAN.

On PON port 3/1, for the uplink data, add the SVLAN 2 to the outer layer of the CVLAN300 and use the default priority (Port priority of the transparent port); for the downlink data, strip the SVLAN.

7 OLT PORT CONFIGURATION MANAGEMENT

7.1 Introduction to OLT Port Configuration

The OLT port here refers to the PON ports on all LPUs and the service network interfaces on all SCUs of the C8000 device.

The basic configuration of the OLT port includes: the setup of startup/shutdown of the port and the setup of the duplex mode and port rate, etc.

The OLT ports of the C8000 device are Gigabit Ethernet ports and the service network interfaces on the SCU can be provided with the speed and the duplex mode in a flexible way.

The Gigabit uplink electrical port only supports the 1000Mbit/s speed, it also supports the full-duplex or half duplex mode. The user can select the appropriate port speed in accordance with actual needs; however, when it is in the half-duplex mode, the speed cannot be 1000Mbit/s.

To avoid the link down of port due to the careless operation of the user, the speed and the duplex mode of the current C8000 system is fixed to the auto-negotiation (auto). The system can, in accordance with the device connected, provide the most appropriate port working mode.

The MDI/MDIX type of the port is the port jumper type, of which, the MDI refers to the Medium Dependent Interface and the MDIX refers to Medium Dependent Interface Crossover.

Figure 7-1 Connection between MDI and MDIX

Generally, the MDI port is for router and PC and MDIX port is for switch. The direct


86

cable can be used to connect the MDI port and the MDIX port while the crossover cable must be used to connect two MDI ports.

7.1.1 Basic Configuration of OLT Port

In the C8000 system, the jumper type of the MDI interface is normal and the jumper type of the MDIX is across, at the same time, the C8000 system supports the self-adaption of the jumper type of ports, enabling the users free from the puzzle in the selection of the direct connection or the crossover cable. At present, the jumper type of the port is the self-adaption, so as to prevent that the port is unable to link up due to the carelessness of users.

The maximum frame length defined by the Ethernet standard is 1518 bytes, but in certain occasions, such as accelerating the file transfer, the ultra-long frame is very effective for improving the efficiency of network transmission. The maximum length of ultra-long frame supported by C8000 is 9216 bytes.

7.1.2 Broadcast/ Multicast/ Unknown Unicast Storm Suppression Configuration

By the following configuration, the user can restrict the flow of certain kind that is allowed to be received by the port. When the flow exceeds the threshold set by the user, the system discards the packet over the flow limitation, thus lowering the proportion of the flow to a reasonable range and ensuring the normal operation of network services.

7.1.3 Configuring the Port Flow Control Function

After the flow control function of the devices of the terminal and the opposite terminal, if the device of the terminal happens to the congestion:

When the device of the terminal sends the message to the device of the opposite terminal, it needs to inform the device of the opposite terminal to pause sending packets or slow down the sending of packets.

After the device of the opposite device receives the message, it will inform the


89

device of the terminal to pause sending packets or slow down the sending of packets, thus avoiding the occurrence of the packet loss and ensuring the normal operation of network services.

8 PON PORT ISOLATION CONFIGURATION

MANAGEMENT

8.1 Introduction to PON Port Isolation

By configuring the PON port isolation, the user can realize the isolation of PON ports and the layer 2 data between ONUs of different PON ports, enhancing the network security and helping the operator's management.

Note:

After configuring the PON port isolation, only the packet between PON ports can not be exchanged, but the communications between PON ports and the service network interface, and the communications between service network interfaces will not be affected.

The PON port isolation has nothing to do with the VLAN of the PON port. Even the PON ports belong to the same VLAN, the communications between PON ports after the isolation cannot be achieved.

8.2 Configuration of PON Port Isolation

By configuring the following items, the user can realize the isolation of PON port.

9 PON CONFIGURATION MANAGEMENT

9.1 Downlink Encryption Management Because the EPON system is applied the broadcast form in the downlink direction of

data transmission, the malicious user is easy to intercept the information of other users of

the system. To improve the confidentiality of data, it needs to provide the encryption to

the data at the downlink direction.

The system supports the standard encryption (Standard, that is, AES128 encryption) and

triple churning. The user can encrypt the downlink data for a ONU with the designated

purpose.

[Note] For the security of data transmission, it is recommended to encrypt the downlink

data sending to ONU from PON.

9.2 Configuring the Maximum Distance The main objective of configuring the maximum distance is to ensure each ONU can be

successfully registered. The physical distances between OLTs are different, resulting in

that the round-trip time changes in microsecond. Due to the difference in the round-trip

times, if there is no enough isolation space, the signals from different ONUs may reach

the receiving terminal of the OLT device at the same time (or partial overlap in time),

leading to the conflicts between uplink signals.

To avoid these conflicts, the EPON system uses the time tag method to measure the

distance. The time tag method realizes the synchronization based on the time tags of the

EPON system and realizes the distance measurement based on the difference between

the time tag value received and the time tag shown in the local clock counter. The results

of distance measurement can be used to obtain the RTT value that can be used to adjust

the ONU sending delay and narrow the intervals between ONU sending window, thus

enhancing the utilization of uplink channels and reducing the time delay. The maximum

distance configuration is actually to configure the RTT, the two parameters can be

converted by formula.

[Note]: the command cannot play a role in the adjustment of the optical power.

9.3 Configuring the DLF Forwarding Policy DLF packet refers to the data packet of destination lookup failure, mainly the data packet

that fails to find the relevant address entries in the address table of the system. There are

many reasons for DLF packets, but in general, when a large number of DLF packages

emerge, it is abnormal, because a large number of DLF packets will greatly occupy the

normal bandwidth and will affect the transmission of normal service flow of users.

Therefore, the processing methods suitable for the DLF packets are very important.

There are two forms: Forward and discard. When distinguishing the downlink direction


100

from the uplink direction, the following forms can be extended, such as forwarding,

uplink discard, downlink discard, double-direction discard.

The main task for configuring the forwarding strategy of DLF is to meet the demands of

users in different network application environment. The system support four kinds of

modes based on the DLF forwarding strategy: forwarding, uplink discard, downlink

discard, double-direction discard.

[Note] By default, the system forwards the processing of the DLF packets.

9.4 Configure the Port Control The main task of the PON port control is to provide a kind of bandwidth management

strategy for the downlink data stream or the P2P data streams between ONU under the

PON port, the two-layer management is supported; specifically, high priority and low

priority, and the configuration on eight queues is allowed, for each queue, the separate

level can be configured.


102

When data congestion happens, the scheduling in accordance with the priority of the data

stream is made, thus realizing the aim of control.

9.5 Configure the Protection Switching of Trunk Fiber The main task of the trunk fiber protection is to protect the trunk fiber connected to the

PON port by the double-path fiber redundancy backup. In the general network

applications, the trunk fiber comes from one PON port and is connected with each

ONU after passing through the optical splitter, once the trunk fiber has troubles, all

ONUs connected to the PON will cause the disruption of services. Under some special

application environment when the requirements on the stability and reliability of data

services are high, the users can greatly enhance the security and stability of data

services by the protection switching of trunk fiber.

The trunk fiber protection uses two optical interfaces for the service transfer, one of

which is A port and the other of which is B port. Under normal circumstances, B port

transfers the data and when the fiber connected with B port fails, the system will

automatically detect the abnormalities and then A port is activated, since then, A port

starts the data transmission instead of B port.

The system supports two kinds of switching models, mandatory and automatic, the

mandatory switching allows the user to switch between A port and B port at any time

and the automatic switching is specifically for the circumstances where no one is on

duty, for the latter, the system will, in accordance with the states of A/B fiber-optic links,

determine whether the switching operation is required.


106

[Note] when the trunk fiber protection is applied, the 2: N optical splitter is required to

connect the two-way optical fiber with A port and B port. Only the LPU2P board can

support the optical fiber protection switching. LPU2P provides 4 optical interfaces, but

in fact there are only two PON interfaces inside.

10 ONU CONFIGURATION MANAGEMENT

The ONU device is located at the client end, providing the port connecting with PON for the user. The ONU and the user can be connected with each other via Ethernet. The main functions of the ONU device are to receive the optical signals of the OLT device, translate the signals to the Ethernet data send to the user; and at the same time, translate the Ethernet data of the user and then send the data to the OLT device.

10.1 ONU Device Configuration Management

10.1.1 ONU Authorization Management

For the EPON system, the broadcast is applied at the downlink direction and the time-division multiplexing technology is applied at the uplink data channel, and the uplink data are send in different time slots by the control of OLT in ONU, if the ONU has not been authorized, then OLT will not send the uplink data in different time slots to ONU.

The authorization method of YOTC EPON system is that the MAC address of ONU is bound. It has been identified that only one ONU can be authorized when there is only a PON port. The authorization strategy can be divided into automatic and manual modes.

10.1.2 Configuring the Management Information of SFU-based ONU

For the SFU-based ONU, the binding authority can only be made on the premise that the IP address pool is subject to the configuration management and the VLAN is subject to the management.

10.1.6 Restarting and Deregistering

The user can restart or deregister ONU. The ONU can be divided into the legal ONU and the illegal ONU in accordance with their authorization states, so the restarting and deregistering on the two ONUs are different; specifically, for the illegal ONU, it needs to specify the llid of the ONU for restarting or deregistering; and for the legal ONU, it needs to specify the ONU ID to complete the operation.

10.1.6.1 Prerequisites

For the legal ONU, it needs to be successfully binded, see section 10.1.1 "ONU Authorization Strategy Management” for specific operations.

This operation is mainly used for managing the connectivity of data stream between ONUs under the same PONs, P2P (point-to-point) data refer to the data channels between ONUs, respectively unicast, broadcast and unicast of unknown addresses (dlf) . The system can respectively manage the data of broadcast and unicast of unknown addresses and can regulate the P2P traffic.

Note:

By default, the ONUs under the same PON port cannot communicate with each other, if the communication is required, the p2p function must be enabled, and by default, the p2p discard the dlf packets and broadcast packets. According to IEEE 802.3-2005 protocol, the point-to-point operation between ONUs of the same PON is not supported, we we do not recommend users to use the p2p function.

10.3 Classification and Marking Configuration Management

10.3.1 Introduction to Classification and Marking

The main task of classification and marking is to provide the priority marking on the uplink data stream. The classification and marking can realize the mandatory modification of priority tags. In accordance with the different matching rules for user configuration, the marking on different flows can be realized respectively. At present, the system supports the following matching rules: VLAN ID, Ethernet type, Ethernet Priority,


131

IP type, TOS field, IP Precedence, source port number of transport layer, destination port number of transport layer, source IP address, destination IP address, source MAC ADDRESS and destination MAC ADDRESS, etc.

10.3.2 Classification and tag Template Operation

The user can configure the template for classification and marking in advance and configure the matching rules and operating conditions in the template. In a classification and marking template, the user can configure a number of matching rules. The system supports a maximum of 8 rules.

10.4 SLA Configuration Management

10.4.1 Introduction to SLA

SLA refers to the Service Level Agreement, specifically, the agreement between the service provider and the customers on the key service targets and responsibilities of both parties in the provision of services.

EPON system should use the dynamic bandwidth allocation (DBA) mechanism to improve the utilization of the upstream bandwidth of the system and ensure the fairness and QoS of services. Besides, the EPON system should be able to allocate the bandwidth authorization in accordance with the queue status reported by LLID.

DBA should support the following three kinds of bandwidth allocation:

Fixed Bandwidth: The OLT periodically sends the authorizations of fixed number to the ONU. It is recommended to use the smaller cycle time and the higher grant frequency for bandwidth allocation. The fixed bandwidth is fully reserved for particular ONU or the specific service of ONU, even under the circumstances when the ONU has no fixed uplink bandwidth service flow, the OLT can send the authorization of the fixed bandwidth to the ONU, and the bandwidth can not be used by other ONU. The fixed-bandwidth is mainly used in the ONU with TDM service (or LLID) in order to ensure the smaller transmission delay of the service.

Assured bandwidth: The bandwidth is specifically for ONU; the OLT authorizes the bandwidth in accordance with the REPORT information of ONU. When the actual service flow of the ONU fails to reach the assured bandwidth, the DBA mechanism of OLT should be able to allocate its remaining bandwidth to the services of other ONUs.

Best Effort Bandwidth: When the bandwidth of the EPON interface has not been occupied by the services of higher priority, the ONU can use such bandwidth. The best effort bandwidth is to allocate the authorizations for the ONU by the OLT according to the REPORT information of all online ONUs in the PON system and the occupancy of bandwidth of PON interfaces. The system does not guarantee that the ONU or the specific service of the ONU can get a certain amount of bandwidth. The type belongs to the service of the lowest priority.

The realization of SLA of the EPON system in the downlink direction is by traffic policing. The traffic policing is mainly for limiting the maximum flow rate. When the traffic rate reaches the maximum rate configured, the exceeded traffic will be discarded; as a result, the


134

traffic rate of jagged peaks and troughs is shown

10.4.2 Configuring SLA

This configuration task is to set the service level; the main approach is to realize the different service levels by configuring different types of bandwidth allocation. The EPON system can allocate different bandwidths in accordance with the service demands of different customers. For large and medium-sized enterprises, the EPON system can increase the bandwidth in order to run the services; for ordinary customers, the EPON system can limit the bandwidth to avoid the bandwidth waste.

11 RSTP CONFIGURATION MANAGEMENT

11.1 Introduction to RSTP Protocol

The concepts and principles on RSTP of the device are fully consistent with the Ethernet switch; therefore, the following RSTP protocol is introduced by taking the Ethernet switch as an example.

STP refers to the Spanning Tree Protocol. The protocol can be used in the loop network to block some redundant paths by the regulated algorithm and to prune the loop network into the loop-free tree network, thus avoiding the proliferation and infinite loop of packets in the loop network.

The basic principle of STP is to pass the special protocol message (In the IEEE 802.1D protocol, the protocol message is known as BPDU) between switches, so as to determine the network topology. The BPDU contains enough information to ensure the switch can complete the spanning tree calculation.

The BPDUmainly includes the following contents:

(1) Root Bridge ID :comprising of the priority of the root and the MAC address;

(2) Root path cost :shortest path cost to the root;

(3) Designated bridge ID:, comprising of the priority of the designated switch and the MAC address;

(4) Designated port ID: comprising of the priority of the designated port and the port number;

(5) MessageAge: BPDU age;

(5) MaxAge: Maximum age of BPDU

(7) HelloTime: Cycle for sending BPDU ;

(8) ForwardDelay: Forwarding delay of the of port state;

The following contents will introduce the designated port and the designated switch.


138

Figure 11-1: Designated Port and Designated Switch

For a switch, the designated switch is the one directly connected with the device and responsible for forwarding data packets to the device and the designated port is the one to which the designated switch forwards the data. For a LAN, the designated switch is the one responsible for forwarding data packets to this network segment and the designated port is the one to which the designated switch forwards the data. As shown in the figure, if Lanswitch A forwards the data to Lanswitch B through port Ethernet 0/1, then the Lanswitch A is the designated switch in the BPDU of Lanswitch B and the designated port is the port Ethernet 0/1 of Lanswitch A; the LAN is connected with two switches: Lanswitch B and Lanswitch C, of which, the Lanswitch B is for transmitting the data packets to the LAN, then the designated switch of LAN is Lanswitch B and the designated port is Ethernet 0/4 of Lanswitch B.

The following will explain the calculation of spanning tree by an example. See the following figure for specific network:


139

Figure 11-2: Ethernet Switch Network

To make the information be clear, only the first four items of the BPDU are shown in the example: root ID (indicated by the priority of Ethernet switch), root path cost, ID of designated switch (indicated by the priority of Ethernet switch) and ID of designated port (indicated by port number). As shown in the above figure, the priority of Lanswitch A is 0, the priority of Lanswitch B is 1 and the priority of Lanswitch C is 2. See the figure for the path cost of each link, 5, 10 and 4 respectively.

(1) Initial state: Each port of the switch will generate the BPDU with the root of itself, the root path cost is 0, the designated switch ID is the ID of the switch and the designated port is the port of the switch.

Lanswitch A：

Port Ethernet 0/1 BPDU：{0，0，0，e0/1}


Lanswitch B：



Lanswitch C：

Port Ethernet 0/1 BPDU：{2，0，2，e0/1}。


140

Port Ethernet 0/5 BPDU：{2，0，2，e0/5}。

(2) Select the Optimal BPDU

Each switch sends out its own BPDU. When the port receives the BPDU with priority lower than its priority, the BPDU with lower priority will be discarded and the BPDU of the port will not subject to any change. On the contrary, when the port receives the BPDU with priority higher than its priority, the BPDU with higher priority will be used to update the BPDU of the port, that is, the BPDU with higher priority will replace the original BPDU of the port. After that, the BPDU with higher priority will be compared with the BPDU of other ports, and finally the optimal BPDU will be selected.

The principle for comparison is that the smaller the root ID is, the higher the priority of the BPDU is, if case the root IDs are the same, the root path costs can be compared, the specific method is as follows: Add the root path cost of the BPDU and the corresponding path cost of the port, set the amount to S, the smaller the S is, the higher the priority of the BPDU is. However, if the root path costs are the same, then the designated switch IDs, the designated port IDs and the port IDs receiving the BPDU can be compared in turn. To make the explanation be more clearly, the manual here only describes the comparison of root IDs, by which, the optimal BPDU can be determined.

(3) Selecting the root port and update the BPDU of the designated port in accordance with the blocking redundant links.

The port receiving the optimal BPDU is the root port and the BPDU of the port is not changed; for other ports, when the BPDU of a port blocks the root port in the updating of the process (2), the BPDU of the port remains the same, but the port will not transmit data and only receive but not send BPDUs; if the BPDU of a port is not updated in the process (2), then the BPDU of the designated port must be subject to the following changes: the root ID is replaced into the root ID of the BPDU of the root port; the root path cost is replaced into the sum of the root port cost of the BPDU of the root port and the corresponding root port cost of the root port; the ID of designated switch is replaced into the ID of the switch; the designated port ID is replaced into the ID of the port.

The comparison of various switches is as follows:

Lanswitch A：

Port Ethernet 0/1 receives the BPDU of Lanswitch B, when the BPDU of the port has the priority higher than the priority of the BPDU received, the BPDU received will be discarded, similar to the port Ethernet 0/2. Lanswitch A finds the roots and the designated switches of the BPDU of each port belong to the Lanswitch A, then Lanswitch A believes


141

it is the root and the BPDU of each port is not changed and then it sends out the BPDUs periodically. The BPDUs of the two ports are as follows:

Port Ethernet 0/1 BPDU{0，0，0，e0/1}。

Port Ethernet 0/2 BPDU{0，0，0，e0/2}。

Lanswitch B：

When the Port Ethernet 0/7 receives the BPDU from Lanswitch A, if it finds the BPDUs received have the higher priority than itself, then the BPDU of the port will be updated. When the Port Ethernet 0/4 receives the BPDU from Lanswitch C, if it finds the BPDU of the port has the priority higher than that of the BPDU received, then the BPDU received will be discarded.

The BPDU of each port is as follows: the BPDU of the port Ethernet 0/7: {0，0，0，e0/1}; the BPDU of the port Ethernet 0/4: {1，0，1，e0/4}.

Lanswitch B compares the BPDUs of ports, then selects the BPDU of the port Ethernet 0/7 as the optimal BPDU, and the port Ethernet 0/7 is determined as the root port, the BPDU of each port of the switch must be subject to the following update:

The BPDU of the root port Ethernet 0/7 is not changed: {0，0，0，e0/1}. The Port Ethernet 0/4 updates the root ID to the root ID0 in the optimal BPDU, the root path cost is updated to 5, and the designated switch ID is set to the ID of the switch and the designated port ID is set to the ID of the port, and the BPDU is changed into {0，5，1，e0/4}.

Then the designated ports of the Ethernet switch Lanswitch B periodically send out the BPDU.

Lanswitch C：

The port Ethernet0/1 will first receive the BPDU{1，0，1，e0/4} before the updating of the port Ethernet 0/4 of Lanswitch B, and then the updating process will be tripped, after the updating, the BPDU is as follows: {1，0，1，e0/4}.

The port Ethernet 0/5 will receive the BPDU {0，0，0，e0/2} from the Lanswitch A, and then the updating process will be tripped, after the updating, the BPDU is as follows: {0，0，0，e0/2}.

By comparison, the BPDU of port Ethernet 0/5 is selected as the optimal BPDU, when the port Ethernet 0/5 is selected as the root port, the BPDU will not be changed, however,


142

the port Ethernet0/1 will be blocked and the BPDU of the port will remain the same, at the same time, the port will not receive the data transmitted from Lanswitch B (excluding the protocol message of STP) until the spanning tree calculation is made due to same reasons, from example, the link from Lanswitch B to Lanswitch C is down or the BPDU of higher priority is received by the port.

And the port Ethernet 0/1 receives the updated BPDU {0，5，1，e0/4} from Lanswitch B. Because the BPDU received has the higher priority than the original BPDU, the updated BPDU will then be updated into {0，5，1，e0/4} again.

At the same time, the BPDU from Lanswitch A received by the port Ethernet 0/5 will not be updated, and the BPDU remains {0，0，0，e0/2}. By comparison, the BPDU of port Ethernet 01 is selected as the optimal BPDU, and the port Ethernet 0/1 is selected as the root port, its BPDU will not be changed, however, the port Ethernet0/5 will be blocked and the BPDU of the port will remain the same, at the same time, the port will not receive the data transmitted from Lanswitch A until the spanning tree calculation is made due to same reasons, from example, the link from Lanswitch B to Lanswitch C is down.

At that time, the spanning tree is stable and the tree shape is as follows, the root is Lanswitch A:

Figure 11-3: Finally Stable Spanning Tree

To make everything be clear, the manual simplifies the process, for example, the root ID and the ID of designated switch must comprise of the switch priority and the MAC address in the process of actual operation; and the ID of designated port must comprise of the port priority and the port MAC address; in the updating of BPDU, not only the above four items will change, the BPDU will also change in accordance with the fixed principles. But the


143

calculation is almost the same.

The passing mechanism of the BPDU of the spanning tree protocol is as follows:

When the network is initialized, all switches take themselves as the roots, the designated ports of the switches send the BPDU of themselves with the cycle of HelloTime periodically; if the port receiving the BPDU is the root port, the MessageAge in the BPDU is increased in accordance with certain principle, and the timer is started to time the BPDU; if a certain path fails, the root port of the path will no longer receive any a new BPDU and the old BPDU will be discarded due to time-out, thus causing the spanning tree recalculation, generating a new path to replace the failed path and restoring the network connectivity.

However, if the new BPDU after the re-calculation does not spread throughout the network immediately, the old root port and designated port that fail to find the change of the topology will continue forwarding data along the original path; while if the newly elected root port and designated port immediately forward data, the temporary path loop may be caused; therefore, the protocol applies the state transition mechanism, that is to say, before the root port and designated port re-start forwarding data, they must pass through an intermediate state, and the intermediate state can be changed into the forwarding state after the ForwardDelay, which ensures the new BPDU has spread throughout the entire network.

The RSTP achieved in the device is the optimization version of Spanning Tree Protocol. The "Rapid" refers to that the delay when the root port and designated port enter the forwarding state is greatly reduced under certain conditions, thus reducing the time required for the stability of network topology. The convergence time for network change is very important for the high-delay-sensitive applications such as voice, video, etc.

The conditions for the rapid migration of root port status are: the old root port of the switch has stopped forwarding data and the designated upstream port has begun forwarding the data.

The conditions for the rapid migration of port status of the designated port are:

Edge port: the port does not connect with any switches directly or indirectly. In case the designated port is the edge port, it is allowed to directly enter the forwarding state;

The port is connected with the point-to-point link, that is, the port is the main port of the trunk port or the full-duplex port, and the user can configure the port to be the point-to-point connection. If the designated port is connected with the point-to-point link, it can immediately enter the forwarding state after the response is gotten by the handshake with the downstream switch;


144

The switches applied the Rapid Spanning Tree Protocol are compatible with the switches applied the Spanning Tree Protocol. The packets of the two protocols can be identified and applied to the spanning tree calculations.

11.2 OLT RSTP Configuration Management

11.2.1 List of RSTP Configuration Tasks

The configuration tasks can only take effect after the RSTP is started. Before starting the RSTP, the relevant parameters for the device or Ethernet ports can be configured, and after the RSTP is closed, the configuration parameters can be saved, when the RSTP restarts, these parameters will take effect.

The list of RSTP main configuration tasks is as follows:

Enable and Disable the RSTP Features of the Device

Enable and Disable the RSTP Features of the Port

Configure the Working Mode of the RSTP Protocol

Configure the Bridge’s Priority of the Device

Configure the Forward Delay Characteristics of the Device

Configure the Hello-time Characteristics of the Device

Configure the Maximum Sending Rate of the Specific Port

Configure the Specific Port to be EdgePort or Not

Configure the Path Cost of the Specific Port

Configure the Priority of the Specific Port

Configure whether the Specific Port is Connected with the Point to Point Link or not

Under normal circumstances, enabling the RSTP features of the device realizes the RSTP function, in case of special requirements, the configuration of relevant parameters can be made.

Note: After the RSTP features of the device are enabled, part of the network resources will be occupied.

11.2.3 Enable/Disable the Spanning Tree Features of Port

In order to flexibly control the RSTP, it can disable the RSTP features of port, so as to ensure the port does not participate in spanning tree calculations.

11.2.4 Configure the Working Mode of Spanning Tree Protocol

RSTP protocol can communicate with STP protocol. If the bridge running the STP protocol exits in the switching network, the command can be used to configure that the


146

current RSTP protocol runs in mode compatible to STP. Table 11-3 Working Mode of Spanning Tree Protocol Configuration



Configure the operating mode of RSTP protocol to STP compatible mode / RSTP mode

no rstp mode By default, RSTP protocol runs in the RSTP mode.

In case the bridge running the STP protocol exits in the switching network, RSTP protocol can automatically migrate to STP, if it runs in the compatible mode, the manual configuration of users is not needed.

11.2.5 Configure the Bridge Priority of Device

The priority of the bridge of the device determines whether the device can be selected as the root of the entire spanning tree. The priority of smaller configuration can designate the device as the root of the spanning tree.

Table 11-4 Configure the Bridge Priority of Device



Configure the Bridge Priority of Device

rstp bridge-priority pri pri is the priority of the bridge, with the range of 0 ~ 61440 and the smallest particles of 4096.

Restore the bridge priority of device to the default value

no rstp bridge-priority The command can restore the default value of the priority of bridge to 32768.

Note: if the priority of all bridges in the entire switching network uses the same value, then the bridge with the smallest MAC address must be selected as the root. Under the circumstances when the RSTP protocol is enabled, if the priority of the bridge is


147

configured, the spanning tree recalculation will be caused.

11.2.6 Configure the Forward Delay Characteristics of Device

The link failure will trigger the network for the recalculations of spanning tree structure. However, the new configuration information re-calculated cannot immediately spread throughout the network; if the newly elected root port and designated port immediately began the data forwarding, the temporary loopback path may be caused. Therefore, the protocol applies a mechanism of state transition, then the root port and designated port has to pass through an intermediate state before the root port and designated port re-start data forwarding, the intermediate state can only enter the forwarding state after passing through the forward delay which ensures the new configuration information has spread to the entire network. The Forward Delay characteristic of the bridge is relevant to the diameter of the switching network. In general, the larger the network diameter is, the longer the time configured for the forward delay is.

Table 11-5 Configure the Forward Delay Characteristics of Device



Configure the Forward Delay characteristics of the device

Restore the default value to 15 seconds.

Note: if the Forward Delay configuration is too small, the temporary redundant paths may be introduced; if the Forward Delay configuration is too large, the connectivity of the network cannot be restored for a long time. It is recommended that the user applies the default values.

11.2.7 Configure the Hello Time Characteristics of Device

The suitable Hello Time value is to ensure the network bridge can find the link failure in the network but not to take up too much network resources.

Table 11-6 Configure the Hello Time Characteristics of Device Item Command Description


148


Configure the Hello Time characteristics of the device

rstp timer hello centiseconds centiseconds refers to the hello timer with the range of 100~1000 and in unit of hundredths of a second.

Restore the Hello Time of the device to the default value

Note: if the Hello Time value is too larger, the packet loss of link may be caused, and the bridge may believe that there are link failures, as a result, the system may start to recalculate the spanning tree; if the Hello Time value is too smaller, the bridge may frequently send messages, and the burden to network and CPU may be increased. It is recommended that the user applies the default values.

11.2.8 Configure the Max Age Characteristics of Device

Max Age is used to determine whether the information configured is the outdated parameters, the user can implement the configuration according to the actual situation of the network.

Configure the Max Ag characteristics of the device

rstp timer max-age centiseconds

centiseconds refers to the max-age timer with the range of 600~4000 and in unit of hundredths of a second. The value of max-age has the following relations with hello and forward-delay:

2×(forward-delay-1)>=max-age>=2×(hello+1)。

Restore the Max Age of the device to the default value

no rstp timer max-age

Restore the default value to 20 seconds.


149

Note: If the Max Age configuration is too small, the spanning tree calculation will be more frequent and even the network congestion may mistakenly regarded as link failure; if the Max Age configuration is too large, the link failures may be not detected in a timely manner, as a result, the network self-adaptability may be reduced. It is recommended that the user applies the default values.

11.2.9 Configure the Maximum Transmission Speed of a Specific Port

The maximum transmission speed of the Ethernet port has relationship with the physical state and the network structure of the port, the user can implement the configuration according to the actual situation of the network.

Table 11-8 Configure the Maximum Transmission Speed of a Specific Port



Configure the maximum transmission speed of the port

rstp transmit-limit rate-limit rate-limit refers to the rate limit for packet transmission with the range of 1~255 and without any units.

Restore the maximum transmission speed of the port to the default value

no rstp transmit-limit Restore the default value to 3 seconds.

Note: If this parameter is configured too large, too many network resources may be taken up. It is recommended that the user applies the default values.

11.2.10 Configure the Specific Port to be Edge Port or Not

If the current Ethernet port is not connected to the Ethernet port of any other bridges, it needs to configure the port to be edge port, in this way, the port can be directly changed into the forwarding state and the unnecessary migration time can be reduced. If a particular port is configured for edge port, but the port is connected to the port of other bridge, then the RSTP protocol can automatically detect and re-configure as the non-edge port.

-

Restore the port to the default value

no rstp edged-port By default, all Ethernet ports of the device are configured as edge port.

Note: if the current Ethernet ports changes from the non-edge port into the edge port, it is recommended that the user manually configures the parameters as the edge port. RSTP protocol cannot detect whether the non-edge port has been transformed into the edge port. For the port directly connecting with the user terminals, please set the port as the edge port, which may quickly migrate the port to the forwarding state, so as to prevent the unnecessary time wasted in startup.

11.2.11 Configure the Path Cost of a Specific Port

The path cost of the Ethernet port is relevant to the link rate of the port, the higher the link rate is, the smaller the parameter configuration is. RSTP protocol can automatically detect the previous link rate of the current Ethernet port and can convert into the corresponding path cost.

Restore the Path Cost of the port to the default value

no rstp cost By default, the device can directly get the path cost of the port from the link rate.

Note: the path cost for configuring the Ethernet port can cause the recalculation of the spanning tree. It is recommended that the user can use the default values to make the RSTP protocol to calculate the path cost of the current Ethernet port.

11.2.12 Configure the Priority of a Specific Port

Setting the priority of Ethernet port can specify a particular Ethernet port included in the spanning tree. In general, the smaller the value configured is, the higher the port priority is, the higher the likelihood that Ethernet port is included in the spanning tree is. If all Ethernet ports of the bridge use the parameter values of the same priority, the priority of the Ethernet port depends on the index number of the Ethernet port.

Note: the change of the priority of Ethernet port can cause the recalculations of spanning tree.

11.2.13 Configure the Specific Port to be Connected with Point to Point Link or not

The two ports connected with the point to point link can quickly migrate to the forwarding state by the simultaneous transmission of packets, reducing the unnecessary forwarding delay time. If this parameter is configured to automatic mode, RSTP protocol can automatically detect whether the current Ethernet port is connected with point to point links.

Restore the parameter to the default value

no rstp point-to-point Restore the default configuration of auto.


153

Note: the current Ethernet port must be the main port of aggregation port and must be full-duplex mode, only in this way, the point to point link can be configured, or the configuration is invalid. The user can manually configure the connection between current Ethernet port and point to point link, it is recommended to use the automatic mode.

12 LINK AGGREGATION CONFIGURATION

MANAGEMENT

12.1 Introduction to Link Aggregation

The link aggregation, known as port aggregation, aggregates multiple ports to form an aggregation group, so as to share the ingress/egress loads among the member ports of the aggregation group and to provide higher connection reliability.

The basic configuration for the ports of an aggregation group must be same, of which, the basic configuration includes port priority, pvid, port vlan mode, vlan configuration, qos (scheduling algorithms, relations between priority and queue), acl (rules of application)

VLAN configuration includes: VLAN that is allowed to pass through the port and the default VLAN ID of the port.

QoS configuration includes: priority marking, default 802.1p priority, queue mapping, scheduling mode, etc.

Port attribute configuration includes: VLAN types (Hybrid port or Ttransparent port, etc.) that must be consistent.

ACL configuration: applied ACL list

The port of the smallest port number in the port aggregation group is the main port of the aggregation group, and other ports are the member ports of the aggregation group.

Under normal circumstances, the port aggregation does not limit the port rate and duplex mode before the aggregation. But in case of the following circumstances, the system will implement the corresponding operations:

For the port at the DOWN state at the initial state, the port rate and the duplex mode will not be limited in aggregation.

For the port at the DOWN state at present but was at the UP state and the port rate and duplex mode are designated by negotiation or compulsion, the port rate and duplex mode must be same in aggregation.

For an aggregation group, when the rate and duplex mode of the port in the aggregation group change, the system will not release the aggregation, and the ports in the aggregation group will be in the normal working condition. However, the packet


157

loss may happen in the forwarding of the port if the rate of the main port reduces and its duplex mode changes. To ensure the port selection of data stream is under control and the data load balances and other factors, the port selection criteria must be followed to ensure the single data streams uses the same exit as much as possible.

12.2 Link Aggregation Group Configuration

The user can create the aggregation group for port by the following commands. The user can delete any port aggregation group formed, then the port of the aggregation group will completely leave the aggregation group. After the aggregation group of the port is created, the user can manually add/delete member ports.

13 PORT MIRRORING CONFIGURATION MANAGEMENT

13.1 Introduction to Port Mirroring

Port mirroring is to copy the data of the port monitored to the designated monitor port, so as to realizeData analysis and monitoring. Generally, the monitor port is connected with the data monitoring equipment, the administrator can use the equipment to analyze the packet mirrored, to implement the network monitoring and troubleshoot, etc.

Figure 13-1 Port Mirroring

The users can specify the direction of the packet monitored, which can be divided into the following items:

Only monitor the packet received by the port(Ingress packet mirroring)

Only monitor the packet sent by the port (Egress packet mirroring)

Monitor the packet received and sent by the port (two-way packet mirroring)

13.2 Port Mirroring Configuration

C8000 users can use the port mirroring groups to configure port mirroring functions, each port mirroring group is composed a monitor port and several mirror ports. Also, the user can specify the direction of packet being monitored.


161

Note: if the traffic being monitored is over the maximum rate of the monitor port, the packet loss may happen. For example, if the 1Gport is used for monitoring the traffic to and from the 10Gport, more attention must be paid to the packet loss.

A mirroring group can configure a monitor port.

The monitored ports of different mirroring groups should not be the same, that is, one to more port mirroring cannot be made.

The monitor port can be free from the effects of the VLAN in the monitoring of packet.

The same port can be used as the monitor port and port monitored of different mirroring port groups.

13.3 Port Mirroring Configuration Example


PON port 3/1 is the port monitored, the packet received and sent by the port is monitored

PON port 3/4 is the port monitored, the packet received by the port is monitored

14 MAC ADDRESS CONFIGURATION MANAGEMENT

14.1 Introduction to MAC Address

To accelerate the packet forwarding, the switchi requires maintaining the MAC address forwarding table. The MAC address forwarding table is a layer 2port-based forwarding table and is the basis for the switch to realize the rapid layer 2 message forwarding. The contents of the MAC address forwarding table include:

Destination MAC address

VLAN ID of the Port

Number of the Forwarding Port

The switch can get the two-layer message forwarding port number by the MAC address forwarding table, realizing the rapid forwarding of the two-layer message.

The dynamic entries of the MAC address forwarding table are learned by the switch, the learning process is as follows:

If a port (Port 1 in the manual) receives a data frame, the switch will analyze the source MAC address (SA1 in the manual) of the data frame and treat that the message with the destination MAC address of SA1 can be forwarded by the port 1.

If the MAC address forwarding table contains SA1, the switch will update the corresponding entries.

If the MAC address forwarding table does not contain SA1, the switch will add the new MAC address (and the forwarding port of the MAC address) into the MAC address forwarding table as the new entry.

After learning of the source address of the message, the switch starts to forward the message:：

For the message that the destination MAC address has already existed in the MAC address forwarding table, the system will forward the message by hardware directly.

For the message that the destination MAC address does not exist in the MAC address forwarding table, the system will forward the message inside the VLAN where the receiving port is located to all ports except the receiving port, it is


165

generally known as the broadcast operation on message.

Figure 14-1 Switch Learning Forwarding

After broadcasting the message, the switch will implement the following actions in accordance with the response message received or not:

When the device of the terminal receives the response of the destination device on the broadcast message, it shows that the message has been sent to the destination device normally. The response message will include the MAC address of the destination device, and the device of the terminal will add the MAC address of the destination device to the MAC address forwarding table by address learning. Then the new entries in the MAC address table can be used to directly forward the message to the same destination MAC address.

When the device of the terminal does not receive the response of the destination device on the broadcast message, it shows that the message cannot reach the destination device or although the destination device receives the message and no response is not made. Under such circumstances, the terminal cannot learn the


166

MAC address of the destination device. Therefore, at the next time when the device of the terminal forwards the message to the same destination MAC address, it will be sent by broadcast.

The MAC address forwarding table has the limited capacity, to maximize the use of the address forwarding table, the switching table uses the aging mechanism to update the MAC address forwarding table. In case no message from a network device is received in the aging period of time, the entries of the MAC address table relevant to the device will be deleted. The MAC address aging is invalid to the entries of static MAC address table.

The user can manually configure (add or modify) the entries of MAC address table in accordance with the actual situation of the network, the table entries to be added or modified can be the static or dynamic table entries.

Note:

Only the unicast address can be learned through the MAC address learning mechanism, the source MAC address is the message of the broadcast address, it will be directly discarded.

In accordance with the characteristics of the MAC address and the different configuration modes, the entries of the MAC address table can be divided into two categories:

Static MAC address entry: it can be added and deleted by the user manually and it will not be subject to the aging over time. To a network where the devices change smaller, the user can manually add the static address table entries to reduce the broadcast traffic of the network.

Dynamic MAC address entry: it refers to the entries that are subject to the aging over time in accordance with the aging time set by the user. The switch can add the dynamic MAC address table entries by the MAC address learning mechanism, or through the mode manually established by the users.


167

14.2 OLT MAC Address Management

14.2.1 Configure the Aging Time of MAC Address Table

The setting of the suitable aging time can effectively activate the aging functions of MAC address. Too long or short of the aging time set by the user may affect the two-layer switching performance of C8000.

If the aging time set by the user is too long, then the system may save too many outdated MAC address table entries, wasting the MAC address forwarding table resources, thus resulting in that the system cannot update the MAC address forwarding table in accordance with the updates of network.

If the aging time set by the user is too short, the system may delete the effective MAC address table entries, reducing the efficiency of forwarding.

Table 14-1 Configure the Aging Time of MAC Address Table

The command is the system configuration command, effective for all ports. The aging mechanism has only affected on the dynamic (learnt or configured) MAC address table entries.

Under normal circumstances, it is recommended to use the default value of aging time of 300 seconds. Using the parameter of no-aging refers to no aging on the MAC address table entries.

Note:

For the MAC address added into MAC address table by learning, the aging must be completed in the second cycle of the aging cycle.


168

14.2.2 Configure the MAC Address Table Entries

The administrator can manually add and delete the entries in the MAC address forwarding table in accordance with the actual situation. It can delete all MAC address table entries relevant to a port, a MAC or a VLAN, and can also specify the dynamic table entry or static table entry, or can empty the entire MAC address table for re-learning.

15 QOS CONFIGURATION MANAGEMENT

15.1 Introduction to QoS

15.1.1 Traffic

Traffic is the service traffic, the packets passing through the current packet.

15.1.2 Traffic Classification

The traffic classification is to apply the suitable rule to identify the packets with the consistent characteristics. The classification rule is very simple, for example, the traffic with different priority characteristics can be identified in accordance with the TOS field at the head of the IP packets; the classification rule can also be very complex, for example, the packet classification can be made in accordance with the integrated data link layer (L2), network layer (L3), transport Layer (L4) such as MAC address, IP protocol, source address, destination address, source port number, destination port number. See "ACL Configuration Management" for details.

15.1.3 Priority

Priority is in the packet, providing the basis for the network equipment for QoS management. The priority includes 802.1p priority, IP priority, TOS, DSCP, etc. In this chapter, only the concept of 802.1p priority is introduced.

802.1p priority is located at the head of the two-layer packet, suitable for the circumstances of two-layer assured QoS. Figure 15-1 shows the Ethernet data frame structure with 802.1Q tag.

DA SA Type DATATPID Priority CFI VLAN ID

VLAN Tag

Figure 15-1 Ethernet Frame with 802.1QTag Header

The 4-byte 802.1Q tag header contains a 2-byte tag protocol ID (TPID) and a 2-byte Tag Control Information (TCI). The priority field of the TCI bytes is the 802.1p priority, which consists of three bits. The range of the priority field is of 0 ~ 7. The three bits refer to the specified frame priority. There are a total of eight kinds of priorities, mainly for QoS management in case of switching equipment congestion.


176

The name of the 802.1p priority is because the applications of such priorities are defined in the 802.1p specification in detail.

In addition, the local priority is the common concept. The local priority refers to the priority of the outputted queue of the port, with the range of 0～7, corresponding to the outputted queue of the port.

15.1.4 Priority Re-tagging

The priority re-tagging function is subject to the traffic identification by the introduction of ACL, for re-designating the priority for the matched packet. See “ACL Configuration Management" for details.

15.1.5 Packet Filtering

The packet filtering is to filter the service traffic, for example discarding, which will discard the service traffic in line with the traffic classification rule and allow the passing of all traffics. C8000 can filter a variety of information for the service traffic and discard the useless, unreliable and questionable service traffic, thereby enhancing the network security.

The application of the ACL to port can realize the function of packet filtering, see "ACL Configuration Management" for details.

15.1.6 Traffic Policing

If the traffic sent by the user is not restricted, a large number of unexpected burst data of users will make the network be more congested. In order to make full use of the limited network resources and server more users in a better way, it must restrict the traffic of users. For example, restrict the traffic at an interval, so as to give the resources assigned, thus preventing the network congestion caused by emergencies.

Traffic policing is a strategy for limiting the traffic and the resources by the supervision on the traffic specification. The traffic policing must be based on the information that whether the traffic has exceeded the specification, only in this way, the traffic policing can be made in accordance with the assessment results. Generally, the token bucket is used to evaluate the specification on traffic.

The token bucket can be taken as the container for storing token, the bucket must have the suitable capacity. The system will place the token to the bucket at the set rate. When the bucket is full of the tokens, no more tokens can be placed and the extra tokens may overflow.


177

The parameter of the token bucket for settings in assessing the traffic includes:

Average rate: the rate for placing the tokens to the bucket, that is, the allowable average rate of the traffic, in CIR usually (Committed Information Rate).

Burst Size: token bucket capacity, namely, the allowable maximum traffic size of each burst, IN CBS (Committed Burst Size) usually. The burst size set must be larger than the maximum packet length.

EBS (Excess Burst Size)

Once there is a packet, an evaluation must be made. For the evaluation of each time, ensure the bucket has enough tokens available, that is to say, the traffic control is in the permitted scope; under such circumstances, take away the tokens with the number equal to the packet forwarding authority from the bucket; or it indicates that too many tokens have been consumed, then the traffic is exceeded.

15.1.7 Congestion Management

When the network in involved into the severe congestion and the total traffic of the network device is over its link bandwidth, the data frame has to be discarded, the network device has to use the strategy to prevent and control the network congestion, thus ensuring the smoothness of the network and providing some QoS; therefore, the strategies are the congestion control strategies.

IEEE802.3x defines an Ethernet control frame (PAUSE frame) to carry out congestion control, which can implement the PAUSE traffic control configuration for sending and receiving directions. When the sending PAUSE of the port for traffic receiving is enabled, under such circumstances, if the network traffic entered cannot be processed in a timely manner, the PAUSE flow control frame will be sent to the port for traffic receiving at the opposite terminal. When the response of the port for traffic sending to the PAUSE frames is enabled, the port for sending at receiving the PAUSE frame will reduce the traffic sent out, thus preventing the congestion of the port for traffic receiving at the opposite terminal.

See "OLTport Configuration Management" for details.

15.2 Queue Scheduling

In case of network congestion, the problem that multiple packets compete for a port in resource sending must be resolved, usually, the Queue scheduling is used.


178

15.2.1 Strict Priority Scheduling

SP queue scheduling algorithm is designed for the critical service applications, particularly suitable for delay, delay jitter-sensitive applications. The critical service has an important service, that is, in case of congestion, the priority for enjoying the services first must be given to reduce the delay in response. Taking the port that has 8 output queues as example, the priority queue will classify the 8 output queues of the port into eight categories, in 7,6,5,4,3,2,1 and 0 queues respectively, their priorities are lowered one by one.

Figure 15-2 SP Scheduling

SP scheduling algorithm is to send the groups in the queues of high priority in strict accordance with the order from high priority to low priority, when the high priority queue is empty, it will send the groups in the low priority queue. Placing the groups of non-critical services (such as E-Mail) into the queue of low priority can ensure the groups of critical services can be transmitted at first, the groups of non-critical services then will be send at the idle interval in processing the critical services.

Weaknesses of SP are as follows, in case of congestion, if the high priority queue is occupied by groups for a long time, then the packets in the low priority queue will be wasted due to the lack of services.

15.2.2 Round Robin (RR) Scheduling

RR(Round Robin)queue schedules the available bandwidth resources equally divided in each outputted queue of each port, because the opportunity for sending the queue is equal, the scheduling is unable to ensure that the service of higher priority can enjoy the service first.


179

Figure 15-3 RR Scheduling

15.2.3 Weighted Round Robin(WRR) Scheduling

The WRR queue scheduling algorithm is the round robin scheduling between queues, so as to ensure each queue can get a certain amount of service hours. Taking the port with eight priority queues as example, WRR can configure a weighted value for each queue(w7, w6, w5, w4, w3, w2, w1 and w0 respectively), the weighted value refers to the proportion of resources obtained. For example, to the 100M port, it can configure the weighted values for the WRR queue scheduling algorithm to be 50,50,30,30,10,10,10 and 10 (corresponding to w7, w6, w5, w4, w3, w2, w1and w0 respectively), in this way, it can ensure that the queue of the lowest priority can get the bandwidth of 5Mbit/s, resolving the shortcoming that the packets in the low priority queue may not get the services for a long time in the application of SP scheduling.

Figure 15-4 WRR Scheduling

The advantages of the WRR scheduling are that, although the scheduling of multiple queues are subject to the round robin, for each queue, the service time slice is not allocated fixedly, if a queue is empty, the next queue scheduling is switched to, in this way, the bandwidth resources can be fully utilized.


180

15.2.4 Scheduling combined with Strict Priority and Weighted Round Robin (SP + WRR)

SP + WRR scheduling algorithm combines the advantages of SP algorithm and WRR algorithm, for some outputted queue (such as the packets of network control protocol, TDM services and other corresponding queues), the SP scheduling is applied to ensure the delay, jitter and other QoS features of critical services; for the services of other priorities, the WRR scheduling mechanism is applied for making full use of bandwidth resources.

15.3 Configuring the QoS

The section of the manual only introduces the "Queue priority mapping" and "Queue scheduling", for other information, please refer to "OLT Port Configuration Management", "ONU Configuration Management" and "ACL Configuration Management".

15.3.1 Configuring the OLT QoS

The OLT port of the C8000 supports 8 output queues, and the queue mapping and queue scheduling operations are made in accordance with the 802.1p priority of the packet. The C8000 OLT terminal supports the queue scheduling algorithms of SP, RR,WRR and SP+WRR.

15.3.1.1 Queue Priority Mapping

As shown in Figure 15-2 and Figure 15-4, before the packet enters the ports and outputs the queue, the priority classification must be made first, and then the packets are sent to the output queues of different priorities in accordance with the classification. In the C8000 system, the packet classification is based on 802.1p priority (or known as cos), the type of output queue that the message with a certain priority is to be sent is designated in accordance with the queue priority mapping.

Note: for the tag without 802.1Q into the port, that is, the packet without VLAN Tag, the system provides a default VLAN Tag. The tag uses the default VLAN ID of the port as the value of the VID field and uses the default priority of the port as the value of the 802.1p priority field. The packet scheduling in the system follows the default priority.

Through the following configurations, the user can configure the mapping between queue priorities.

The qos sched command can take effect only when it is in the port of sending packets, that is, in the port of egress.

When the scheduling is wrr, if the weighted value of the outputted queue is 0, it indicates that the strict scheduling must be applied to the queue; under such circumstances, the scheduling method is SP + WRR.

The weight ratio of queue is the weighted value of the queue/ the sum of the weighted values of all queues.


183

By default, queue scheduling mode is SP + WRR.

By default, the weight weighted values of queues 0-5 are 1,1,1,2,2 and 3 with the weight ratio of 10%, 10%, 10%, 20%, 20% and 30%; the weighted value of queues 6 and 7 is 0, that is, the strict scheduling is applied. In case of congestion when the port sends the queue, if the queues 6 and 7 have packets, the packets of the queues will be sent first, after that, the WRR scheduling may be applied on the other six queues.

15.3.1.3 OLT QoS Configuration Example


Classify the packets into the uplink port 3/1, the mapping between the 802.1p priority (COS) and the output queue is as follows: 0－>2，1－>0，2－>1，3－>3，4－>4，5－>5，6－>6，7－>7.

Set the scheduling mode of the GE port9/1 into the weighted round robin scheduling, and the weights are 10,5,10,10,5,10,5 and 10 respectively.

16 ACL CONFIGURATION MANAGEMENT

16.1 Introduction to ACL

ACL (Access Control List) is to realize the packet filtering by configuring the matching rules and processing operations of packets. The network device needs to configure a series of matching rules for filtering packets, so as to identify the packets to be filtered. After the particular packets are identified and classified, the processing on the corresponding data packet in accordance with the pre-set processing mode can be made; the processing mode can allow or forbid the passing of data packets.

The data packet matching rule defined by the ACL can be used by other functions that require distinguishing flows, such as the definition of the flow classification rules in QoS.

Depending on application purposes, the ACL can be divided into the following categories:

Standard ACL, range of 1-2000. The rule is developed only in accordance with the source IP addresses of the data packet.

Extended ACL, range of 2001-5000. The rule is developed in accordance with source IP address of the data packet, destination IP address, protocol type of the IP, source protocol port, destination protocol port, IP service type and other layer 3 or layer 4 information.

Link-layer ACL, range of 5001-8000. The rule is developed in accordance with source MAC address of the data packet, destination MAC address, two-layer protocol type, VLAN and other two-layer information. In the ACL of the type, only one rule can configure a matching rule.

User-defined ACL, range of 8001-10000. The ACL in fact is the random matching of 80 bytes of the header by the use of wildcard characters. (Not support)

You do not need to specify the type while creating the ACL, the scope has determined the type.

You can set the effective time for the ACL, that is, when the ACL is applied to the port, it can be effective only in the effective time, in case no effective time is set, it will be effective when it is applied to the port.


188

The wildcard characters in ACL are opposite to the common IP subnet mask. The wildcard characters are the bit sequence with specified length, of which, when the bit is 1, indicating that no matching is needed, when the bit is 0, the matching is required.

ACL Matching Order

ACL may contain multiple rules and each rule may specify the different ranges of packets. If so, the order of matching in rules exists in the message matching.

To facilitate the management and the matching order of the multiple rules of ACL, group the ACL rules, in each group, the ACL rulers have the relative priority with the range from 1 to 16, the higher the value is, the lower the priority is, the group with higher priority must be matched first. In case the two groups with the same priority, the matching is made based on the increasing sequences of the ID of the groups.

ACL rule group can have a maximum of 16 rules; such rules can be matched base on the increasing sequences of the IDs of the rules.

In the manual, the ACL rule group is called as ACL list and the ACL rule is called as rule.

16.1.1 Mode of Application of ACL in OLT

Apply the defined rule on OLT to ge or pon interfaces to realize the data packet streaming and processing.

For the rule definition, it must first create and define the rule list, that is, the ACL list and then create the rule in the ACL list. After the rule is created, it needs to define one or more matching conditions for the rule and the corresponding processing.

The ports that the rules are applied are in the unit of ACL list.

16.2 ACL Configuration

16.2.1 Configuring the ACL list

10, 000 ACL lists to the maximum and each list has the following attributes:


189

List Number (ID): for uniquely identifying the ACL list, with the scope from 1 to 8000, when the priorities of multiple ACL lists are the same, the matching order can be determined in accordance with the ID, the ACL list with the smaller ID can be matched first. The ID is specified when creating the ACL list, which cannot be modified.

Number of Rules: the rules in an ACL list

Priority: When more than one ALC lists are applied to a port, the priority can determine their matching order.

Name: to describe the ACL list.

Applied or not: to identify whether the rule has been applied to the interface or not.

Application interface list: the interface list where the ACL list has been applied, if no ACL list is applied, then the interface list is empty.

Where the priority and the name can be configured by the user after the ACL list is created, but the priority can only be modified when the ACL list is not applied to any an interface.

16.2.1.1 Create and Delete the ACL Rule Group

Carry out the following operations under the config view:

Table 16-1 Create and Delete the ACL Rule Group

16.3 ACL Rule Configuration

ACL rules need to be created and configured under the ACL view, an ACL view corresponds to ACL rule groups. The configuration command under the ACL view is specifically for the current ACL rule group.

An ACL rule group has a maximum of eight rules, each rule has the following attributes:

Rule Number (ID): for uniquely identifying the rules in the rule groups, with the range from 1 to 8. In a rule group, the number is used for the matching order of rules, the smaller the number is, the earlier the matching is. The rule number is specified in creating, no further modification is allowed.

Matching conditions: a rule can contain multiple match conditions, the data packets can be regarded to be matched with the rules only consistent with all conditions. If the matching conditions are not defined, it needs to carry out the matching processing on the inputted data packets.

Matching processing action: it needs to process the data packets in line with all conditions; one rule corresponds with one processing action. If the matching processing action of the rule is not defined, the rule will not affect the processing of the data packets.

When the ACL rule group has been applied to the port, the configuration on the port of the rule group cannot be made, for example, create rules, and modify the matching conditions and matching processing action of the rules that have been created.

For the configuration of the rule, it needs to create the rules first and then set the matching conditions and matching processing action. The matching conditions that available for setup are as follows: source MAC address, destination MAC addresses, Ethernet type (for example, ARP, PPP, RARP, etc.), destination IP address, source IP address, IP type (eg, ipv4, ipv6, etc.), IP packet protocol type (such as TCP, UDP, ICMP, etc.), VLAN ID, 802.1P priority, IP priority, DSCP, L4-source protocol port, L4 destination protocol port and others. The matching processing actions available for setup are as follows: enter the specified outputted queue, modify the 802.1P priority, modify the IP priority, modify the DSCP, discard, allow the passing, etc.

17 LAYER 3 STATIC ROUTER MANAGEMENT

17.1 Introduction to L3 Static Router

In the IP network, the parties for communications may not in the same network segment; under such circumstances, the router must be used for resolving the problem.

Generally, in addition to the router, many switches have the L3 function, that is to say, many switches have the functions of L3 router. The C8000 is a two-layer device, no route switching can be achieved. To solve the above problem, the C8000 is provided with the function of the L3 router.

The L3 router of C8000 is a static router, mainly translating between VLANs so as to realize the functions of the L3 router. The C8000 can configure an IP address for each VLAN, the host in the VLAN can use the IP address of the VLAN as its gateway; by the setup of the static router, the route switching can be realized inside the C8000.


199


When host A and host B are in different network segments, host A is connected with C8000 by onu, the service network interface of the C8000 is connected with the router and then it is routed to 189.40.35.0 network segment by the router. Connection description is as follows:

1) Set the IP of host A to 192.168.80.88/24, connect host A with the Lan 1 interface of 0400 ONU.

2) Set the Lan port of ONU to the transparent mode and then connect with 1/1PON port of the C8000

3) Connect the C8000 with the port1 of the router by 3/1. 4) Connect the router with the network segment of 189.40.35.0/24 by port2.


Figure 17-1 Typical Layer 3 Router


Configuration instructions:


200

1) Set the VLAN mode of ONU to the transparent mode with the view to transmitting all data of PC and C8000 in the transparent mode. 2) Open the master L3 switch of C8000. 3) Add VLAN 5 to C8000, and set the IP address of L3 interface to 192.168.80.1/24, and add PON port 1/1 to the VLAN, set the vlan mode of the VLAN to the untagged mode and the pvid to 5, with the view to ensuring the data without vlan from the PC transmitted in the transparent mode can enter the C8000. 4) Add VLAN 6 to the C8000 again, and set the IP address of L3 interface to 192.168.70.1/24, and at the same time, add the service network interface 3/1 to the VLAN, set the vlan mode of the VLAN to the untagged mode and the pvid to 6, with the view to ensuring the data without vlan from the router can enter the C8000. 5) Set the IP address of the port 1 of the router to 192.168.70.2/24 and set the IP address of the port 2 to 189.40.35.1/24. 6) Add a static router to the C8000, set the address of the next hop device access to the 189.40.35.0 network segment to 192.168.70.2/24, that is, when the destination address is the 189.40.35.0 network segment, it will be handed over to 192.168.70.2/24 port. 7) Add a static router to the router, set the address of the next hop device access to the 192.168.80.0 network segment to 192.168.70.1/24, that is, when the destination address is the 192.168.80.0 network segment, it will be handed over to192.168.70.1/24 port. At the same time, configure the rule for the translation between the 189.40.35.0 network segment and the 192.168.70.0 network segment on the router.

In this way, the HOST A can be connected with HOST B by ping, by the twice L3 switching through the C8000 and the router, the data of both sides can be connected with each other.

Configuration Procedure：

$ Set the L3 to the enable mode

C8000(config)# l3-interface enable

$ Configure vlan5, set the IP address, add the pon port to the vlan and set the pvid


C8000(config-vlan-5)#l3-interface ip-address 192.168.80.1 255.255.255.0



$ Configure vlan6, set the IP address, add the pon port to the vlan and set the pvid



201

C8000(config-vlan-6)#l3-interface ip-address 192.168.70.1 255.255.255.0



$ Add the static router

18 MULTICAST CONFIGURATION MANAGEMENT

18.1 Introduction to Multicast

There are three kinds of message transmitting in the network: Unicast, Broadcast and Multicast.

The Unicast mode is applicable to the network with fewer users and the Broadcast mode is applicable to the network with more users, but the two modes have the common ground that when the user quantity in the network requiring the certain information is uncertain, the two modes are inefficient. And the Multicast mode can resolve the problem. When some users in the network require specific information, the Multicast message sender (ie, Multicast Source) only sends the message once, with the Multicast Routing Protocol, the tree router for the Multicast data packet is established to copy and distribute the message to be transmitted at the node where is close to the client as much as possible.

The point-to-multipoint network architecture of EPON supports the Multicast protocol and is the best access means for the video Multicast service. Therefore, the use of the Multicast features of the network to provide some new value-added services is allowed in the EPON system, including online broadcasting, Internet TV, remote education, telemedicine, Internet radio stations, real-time video conferencing and other Internet information services.

18.1.1 Multicast Frame

The parts in the Multicast mode can be divided as follows:

"Multicast Source": message sender.

"Multicast Group": a number of recipients receiving the same message. The "Multicast Group" is free from geographical boundaries.

"Multicast Group Member": Each Multicast message recipient.

"Multicast Router": the router that can provide the functions of Multicast routing; the Multicast Router can be one or more multicast group members or can manage the multicast group members.

Although the Multicast technology is complex, its fundamental purpose is to transmit


203

the information from the Multicast source to recipients in the Multicast mode, and meet the demands of recipients on message. Multicast is a form of end to end service, which is divided from bottom to up of the protocol layer, the Multicast mechanism includes the following four parts:

Addressing mechanism: by the Multicast addresses, to transmit the information from the Multicast source to a group of recipients.

Host Registration: to allow the dynamic joining and leaving of the host to a Multicast Group and to realize the registration of Multicast members.

Multicast Router: to construct the message distribution tree for Multicast routing and to transmit the message from the Multicast source to the recipient.

Multicast Application: Multicast Source must support the Multicast application software such as video conferencing, TCP/IP protocol stack must support sending and receiving of Multicast packets.

Take the network architecture of IPTV as an example to show the application of Multicast: the digital TV system is composed of Multicast server, IP MAN, access network and home network, see the following figure:

Figure 18-1 EPON System Multicast Architecture

The flow for the EPON system to realize the video-on-demand is as follows:

Step I: the user IP TV set-top box (STB) or a PC obtains an IP address from the DHCP


204

server by sending the DHCP request;

Step II: the authentication server verifies the user name and password reported by the STB/PC, after passing through the certification, the TV program and the video-on-demand program list provided by the video server can be obtained from a particular video service website;

Step III: The user can use the remote control to select TV programs or video on demand programs;

Step IV. After the program is selected, the STB/PC will send the IGMP Multicast join request message to the Multicast router;

Step V: The IGMP join request message passes through the ONU, the ONU monitors and records the message, and at the same time, the ONU establishes the relations between the group members and the ONU port and forms the Multicast filtering table;

Step VI. The IGMP join request message passes through the OLT, the OLT monitors and records the message, and at the same time, the OLT establishes the relations between the broadcast ID and Multicast group members and the corresponding ONU ID, and then based on the Multicast application permission of ONU, the Multicast Mapping Table is formed, which is distributed to ONU through the management channel; and then the IGMP join request message is sent to the Multicast router;

Step VII: after receiving the IGMP join request message, the Multicast router establishes the Multicast Mapping Table (Relations between Group and VLAN) and forwards the Multicast stream;

Step VIII: After receiving the Multicast stream, the OLT fills the broadcast ID to the LLID field of the lead code of the Multicast message and sends the Multicast stream to ONU;

Step IX: after receiving the message with the broadcast ID, the ONU, according to the Multicast Mapping Table issued by the OLT, receives the corresponding Multicast streams, checks the Multicast filtering table and forwards the Multicast stream to the user port initiating the IGMP request message.

Step X: The user can watch the Multicast program.

The key is to establish the Multicast Mapping Table in the Multicast Router, to establish the Multicast Forwarding Table on OLT and to copy the video stream.


205

18.1.2 Introduction to Multicast Address

18.1.2.1 Multicast IP Address

In accordance with the regulations of IANA (Internet Assigned Numbers Authority), the IP addresses are divided into five classes, namely, Class A, Class B, Class C, Class D and Class E. The Unicast packets use Class A, Class B or Class C in accordance with the network size, and the destination addresses of Multicast packets use Class D, that is to say, the Class D addresses cannot be in the source IP address filed of IP message. The Class E addresses are for future use.

In the IP Multicast environment, there are a group of destination addresses of the data packet, which form a group address. Once all message recipients are added to a group, the data flowing to the address can be immediately transmitted to the recipients, all members of the group can receive the data packet, the group is known as "Multicast Group".

The Multicast group has the following characteristics:

All members in the Multicast group are dynamic; the host can join and leave the Multicast group at any time.

The Multicast groups can be permanent or be temporary.

The Multicast group with the Multicast addresses assigned by IANA is known as Multicast group (or reserved Multicast group).

For a permanent Multicast group, pay more attention to the following information:

The IP address of a permanent Multicast group remains the same, but the group members can change.

The number of members in the permanent Multicast group is free from any restriction, even zero is OK.

The IP Multicast addresses that are not be reserved for Multicast Group to use can be used by a temporary Multicast group.

The range of Class D Multicast addresses is from 224.0.0.0 to 239.255.255.255, see Table 18-1 for scope and meaning.

Table 18-1Scope and Meaning of Class D address Scope of Class D Address Meaning


206

224.0.0.0～224.0.0.255 Reserved Multicast address (address of a permanent group), the is ADDRESS 224.0.0.0 is preserved and not distributed, other addresses are for routing protocol to use

224.0.1.0～231.255.255.255

233.0.0.0～238.255.255.255

ASM (Any-Source Multicast) Multicast Address available to the user (the address of a temporary group), valid within the whole network

239.0.0.0～239.255.255.255 Multicast address of local management, only valid within a particular local scope

In accordance with the regulations of IANA, the network segment address from 224.0.0.0 to 224.0.0.255 is reserved for the routing protocol of local network. The common IP Multicast address list reserved is as follows:

Table 18-2 Reserved IP Multicast Address List Scope of Class D Address Meaning

224.0.0.1 Addresses of all hosts 224.0.0.2 Addresses of all Multicast routers 224.0.0.3 Not assigned 224.0.0.4 DVMRP (Distance Vector Multicast Routing) Router 224.0.0.5 OSPF (Open Shortest Path First) Router 224.0.0.6 OSPF DR (Open Shortest Path First Ddesignated Router ) 224.0.0.7 ST (Shared Tree) Router 224.0.0.8 ST (Shared Tree) Host 224.0.0.9 RIP-2 Router 224.0.0.11 Active agent 224.0.0.12 DHCP Server / Relay Agent 224.0.0.13 All PIM (Protocol Independent Multicast) Routers 224.0.0.14 RSVP (Resource Reservation Protocol) packet 224.0.0.15 All CBT (Core-Based Tree) Routers 224.0.0.16 Designated SBM (Subnetwork Bandwidth Management) 224.0.0.17 All SBMS 224.0.0.18 VRRP(Virtual Router Redundancy Protocol)

224.0.0.19-224.0.0.255 Unspecified

Note:

Similar to the circumstances that the IANA reserves the network segment of 10.0.0.0/8 as the private address for IP Unicast transmission, the IANA also reserves the network segment of 239.0.0.0 to239.255.255.255 as the private address for IP Multicast, these addresses are in the scope of management.


207

By the management on the addresses in the scope of management, the definition on the scope of Multicast filed can be realized flexibly to realize the isolation of addresses of different Multicast fields, helping to re-use the same Multicast addresses in different Multicast fileds which at the same time is free from any conflicts.

18.1.2.2 Multicast MAC Address

At the time when the Ethernet transmits the Unicast IP packets, the destination MAC address is the MAC address of the recipient. However, in transmitting the Multicast message, the transmission target is a group with uncertain members rather than a specific recipient, so the Multicast MAC address is used.

Under normal circumstances, the lowest bit of the maximum byte of the Unicast MAC address is 0 while the lowest bit of the maximum byte of the Multicast MAC address is 1, see the following figures:

Figure 18-2 Comparison between Multicast Address and Unicast Address

In this way, the data link layer can determine whether the data frame received is a Multicast data frame or not in accordance with the bit.

18.1.2.3 Mapping Relations between Multicast IP Address and Multicast MAC Address

The IANA regulates that the high 24bit of Multicast MAC address is 0x01005e and the low 23bit of the MAC address is the low 23bit of the Multicast IP address, the mapping relationship is shown in Figure 18-3:


208

XXXX X

xxxx xxx1

xxxx xxxxxxxx xxxxxxxx xxxx1110 xxxx

xxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxx

32-bit IP address

48-bit MAC address

25-bit MAC address prefix

5 bits lost

23 bits mapped

... ...

18-3 Mapping Relationship between Multicast IP Address and Multicast MAC Address

Because the high 4bit of the IP Multicast address is 1110, representing the Multicast identification, in the low 28bit, only 23bit is mapped to MAC address, then the IP address loses 5bit messages, the direct result is that 32 IP Multicast addresses are mapped into the same MAC address.

It can be seen that the MAC address corresponds with the low 23 bits of the IP address. For example, when the IP module informs the software of the data link layer to add a Multicast Group 224.10.10.10, the data link layer will form a MAC address of 01--00--5E--0A--0A--0A, then take the low 23 bits of the Multicast IP address to add into the receiving address list while the high bits then follow the above rules.

18.1.3 Multicast Management Protocol IGMP

IGMP (Internet Group Management Protocol), as the Multicast Group Management Protocol runs between hosts and Multicast routers, defines the establishment and maintenance mechanisms on the Multicast member relationship between user host and Multicast router.

18.1.3.1 Introduction to IGMP

The IGMP protocol can be divided into IGMP Proxy and IGMP Snooping in accordance with working mechanisms.

The realization principle of IGMP Proxy: the switch blocks the IGMP message between the user and the router to establish the Multicast table, the service network interface on the Proxy device then plays the host role and the uplink port then plays


209

the router role.

The realization principle of IGMP Snooping: the switch intercepts the messages reported by the host to the IGMP members of the router to form the corresponding relationship between the group member and the switch interface; the switch then, according to the corresponding relationship, only forwards the Multicast data packet received to the all interfaces of group members.

It can be known that the functions of IGMP Proxy and IGMP Snooping are the same but the principles differ from each other; specifically, the IGMP Snooping obtains the relevant messages only by intercepting the IGMP messages but IGMP Proxy has to intercept the IGMP requests of end users, processes to the requests and then forward to the upper router.

The OLT terminal of the C8000 system applies the IGMP Proxy protocol to realize the Multicast, the specific process is as follows: when the OLT receives the IGMP Join message, the OLT starts the IGMP Proxy function, intercepts the Join message and implements the authentication; after that, the following logical check is made: if the Multicast Group that is applying has not been established in the OLT, the OLT sends the IGMP Join request to the upper router and establishes the Multicast Forwarding Table; if the Multicast Group has already been established in the OLT, the OLT directly joins the user to the Multicast Forwarding Table of the OLT, at the same time, the correspondence table of Multicast services and users has been established, and no Join message to the upper router will be sent.

The ONU terminal of the C8000 system applies the IGMP Snooping mode, when the ONU receives the IGMP join message, the message of Multicast Forwarding Table can be obtained by interception, but the IGMP message passes through the ONU by the transparent transmission.

18.1.3.2 IGMP Message

The IGMP Protocol is developed based on the Host Membership Protocol, and there are two versions available: IGMPv1 (RFC1112) and IGMPv2 (RFC2326). The host uses the IGMP message to inform the local Multicast routers to receive the host group address of the Multicast traffic. If the host supports IGMPv2, it can inform the Multicast router to withdraw from a host group. The Multicast router, by the IGMP protocol, maintains a host group member table for each port and monitors the members of the host group in the table periodically to determine whether the host group survives.


210

The IGMP message is placed in IP message to transmit. The message of IGMPv1 is shown in Figure 18-1-4. The IGMPv1 defines two kinds of messages: host member enquire and host member report. When the host wants to receive a Multicast group, it sends IGMP Report message to the local Multicast router and informs the Multicast addresses to be received. The Multicast router, after the receipt of IGMP Report message, can add the host to the specified Multicast, and within the set cycle, it sends the IGMPQuery message to the Multicast address of 224.0.0.1 (representing the hosts supporting the Multicast). If the host continues to receive Multicast traffic, the IGMP Report message must be sent.

The IGMPv2 message is shown in Figure 18-5. Different from the IGMPv1, the IGMPv2 message integrates the version filed and the message type and regards the unused field as the "Maximum response time" field. The type field of the IGMPv2 message defines four kinds of messages:

0x11 - Member enquiry

0x12 - IGMPv1 member report

0x16 - IGMPv2 member report

0x17 - Exit from the host group

The relation between the IGMPv2 and IGMPv1 Protocol is in forward compatible, the device of IGMPv1 can receive the message of processing IGMPv2. In the IGMPv2, it allows the router to implement the "Member Enquiry" on the specified multicast group address, and the host not in the group will not have to respond. If the host withdraws, it can take the initiative to send the IGMPLeave message to the router, and it will not have to withdraw passively as that in the IGMPv1

Note:


228

The igmp mode set only refers to the Multicast working mode of the local C8000 and the default igmp mode of the ONU is igmp snooping.

The router port set must be on the SLU plate, otherwise, the configuration will fail. If the expect black deleted has been provided with the router port of the SLU plate, after it is deleted, the router port configuration will be cleared and all service network interfaces will be restored into the router port by default.

Under the igmp controllable mode, the distinction between users (the corresponding ONU port) uses the VLAN tag of the uplink igmp protocol packet (generally vid 1 refers to port 1, vid 2 refers to port 2, and so forth). When the ONU is set to be multicast-protocol ctc, it will add the valn tag independently in accordance with the inputted port of the packet, and the configuration relevant to the vlan on the port of ONU is not needed.

Under the igmp controllable mode, the distinction between users (the corresponding ONU port) uses the VLAN tag of the uplink igmp protocol packet. In order to forward the uplink igmp protocol packet in the main switcher, it needs to add the corresponding PON port (BCM Terminal) into the VLAN filed representing the ONU port.

All PONs belong to vlan 1 of untagged type. Therefore, if the user is connected to the ONU uniid = 1, the default vlan configuration can be used to transmit the uplink IGMP protocol packets.

When the OLT receives the igmp join message sent by the ONU connected and passes through the permission inspection, the PON port connected with the ONU will be automatically added into the MulticastVlan.

After the ONU restarts, the igmp snooping function ten is enabled, at this time, the multicast-protocol command can be used to switch between igmp snooping and igmp ctc.

If the igmp snooping function is disabled, the multicast-protocol igmp-snooping can only set the igmp mode into the igmp snooping, but it cannot enable the igmp snooping.

See 17.2.2 for the ONU igmp snooping state enable switch.

Select the igmp of ONU to be CTC controllable mode, so as to forbid the igmp snooping function of ONU.

The user’s default permission (ie, no configuration permission for a channel) is “DENY".

Note:

The igmp mode set only refers to the Multicast working mode of local C8000 and the default igmp mode of the ONU is igmp snooping.

The router port set must be on the SLU plate, otherwise, the configuration will fail. If the expected SLU plate deleted has been provided with the router port, after it is deleted, the router port configuration will be cleared and all service network interfaces will be restored into the router port by default.

When the OLT receives the igmp join message sent by the downlink ONU, the PON port connected with the ONU will be automatically added into the Multicast Vlan.

After the ONU restarts, the igmp snooping function ten is enabled, at this time, the multicast-protocol command can be used to switch between igmp snooping and igmp ctc.

If the igmp snooping function is disabled, the multicast-protocol igmp-snooping can only set the igmp mode into the igmp snooping, but it cannot enable the igmp snooping.

20 ALARM CONFIGURATION MANAGEMENT

20.1 Introduction to Alarm Configuration

After enabling the alarm, if the system has errors or implements some important operations, the OLT alarm event will be triggered, and then the OLT will save the alarm information into the alarm buffer. By the show alarm active or show alarm history command, the current active alarm and the historical alarm of the system can be checked. All alarm information can be sent to the server by the snmp trap and can also be shielded.

The alarm is the notice of the system when it detects failure, including failure alarm and recovery alarm, of which, the failure alarm lasts until the failure is corrected. Not every alarm has the alarm recovery.

The event is the notice generated under normal operation and taking the initiative to prompt the user, including running event and security event. The difference between event and alarms is that: the alarm is the notice reported when the system is abnormal or when the exceptional circumstances may happen, while the event is the notice reported when the system is normal.

Without special remarks, the alarm includes the alarm and the event.

Under the default configuration, all alarms can be automatically printed in the user interface.

21 NETWORK MANAGEMENT CONFIGURATION

21.1 Introduction to Network Management Mode

C8000 OLT device supports the access control of three management means at the same time:

Table 20-1 C8000 Network Management Approach Management

Approach Protocol Description

Console port control CLI The serial port supports the CLI management approach


246

Inband Management CLI(telnet)

SNMP

Inband at the same time supports the CLI mode an Snmp network managemen mode of Telnet

By the snmp management, it can connect with the network management server to manage the C8000 by the graphical network management

Outband Management CLI(telnet)

SNMP

Outbandat the same time supports the CLI mode an Snmp network managemen mode of Telnet

By the snmp management, it can connect with the network management server to manage the C8000 by the graphical network management

The outband management is to provide the management interface by the special physical channel, for the C8000 device, it can realize the management and maintenance by the FE port on the SHM. Generally, the network management can be realized by the direct connection with PC or by the network management channel (The management network separately formed) to separate the network management data from the service data and to establish an independent channel for network management data. In the network management channel, only the important management data, sensitive statistical information, real-time billing information and others can be forwarded. The separation of network management data from service data can improve the efficiency and reliability of network management and help to improve the security of network management data.

For the smaller network structure, the inband management method is appreciated. The inband management can transmit the network management data and service data in the same physical link, when there are many management data (including SNMP data, Netflow data, Radius data, billing data, etc.), the performance of the entire network may be affected, the service data stream may also affect the management data stream; but for smaller networks, the stream of the management data is smaller, then the impact on the performance of the entire network is not obvious, that is to say, the inband management is suitable for smaller network structure. The inband network management channel of the C8000 is realized mainly by service network interface, in the ordinary manner, to maintain the security, a special vlan is used to separate the management channel from other service channels.


247

Note:

For the same gateway, the IP address of the inband cannot be in the same network segment to the IP address of the outband.

248

Figure 20-1Management Network Diagram

21.2 Default Network Management Configuration

When the OLT device of C8000 is not in the same network segment to the network gateway server, that is to say, when the equipment maintenance needs to cover different network segments, the gateway setup must be made. The role of the default gateway is that when C8000 devices are not in a network segment, all data will be forwarded to the default gateway and then will be forwarded by the default gateway.

Configure the default gateway

C8000(config)# gateway 10.10.2.1

C8000(config)# show gateway

%Gateway:10.10.2.1.

C8000(config)#


249

Note:

After the completion of default gateway configuration, no modification is allowed. For the modification, it needs to use the no gateway command to delete the default gateway and then use the gateway command for adding.

At the time when configuring the default gateway, it needs to ensure the IP address of the default gateway is in the same network segment to the local outband or inband IP addresses.

21.3 Outband Network Management Configuration

The configuration of the outband network only requires the configuration of IP address and subnet mask.

The configuration of the IP address of the outband network management is as follows:

C8000(config)# outband ip-address 10.10.1.100 255.255.0.0

Note:

After the completion of the IP address of the outband gateway, it needs to connect the FE port of the C8000 with the PC by a direct cable, and to use the ping mode to check whether the network port is normal.

21.4 Inband Network Management Configuration

The C8000 device provides the function of inband network management by the service network interface or the ONU connected with the PON port, which requires the configuration of IP address, subnet mask, mac address and items relevant to vlan.

Step I: Create the VLAN for inband network management to 1000

C8000(config)#vlan 1000


250

Step II: Add the service network interface 3/1 to the VLAN 1000, set the VLAN to the untagged mode

C8000(config-vlan-1000)#port 3/1 tagged

C8000(config-vlan-1000)#show vlan 1000

---------------------------------------------------

VLAN ID: 1000

Description: VLAN 1000

Tagged ports:

3/1

Untagged ports:

none

Multicast flood mode:

Flood-none (Discard if mcast addr is not found)


Step III: Set the IP address of the inband network management to 10.10.2.100, the mask to 255.255.255.0 and MAC address to 00:00:03:01:02:03

C8000(config-vlan-1000)#inband ip-address 10.10.2.100 255.255.0.0 00:00:03:01:02:03

C8000(config-vlan-1000)#show inband-info

Current state : up

VLAN interface : 1000

MAC address : 00:00:03:01:02:03

IP address : 10.10.2.100

IP netmask : 255.255.0.0


251

Note:

Ensure the VLAN of the inband management channel is separated from the service VLAN to prevent the service broadcast data from entering the CPU of SCU.

In configuring the MAC address of the inband network management, more attention should be paid to configuing the MAC address into the MAC address of Multicast.
