2.0 DragonWave Layer 2 Switch (l2sw) Quantum Release 1.1.5 introduces Layer 2 switch (l2sw) functionality. l2sw is a DragonWave licensed feature and this feature must be enabled in order to access l2sw functionality and command set. DragonWave l2sw is an integrated software feature for the Horizon Quantum that manages the on-board Ethernet switch. It performs Ethernet switching between Ethernet ports at wire-speed and performs Ethernet link management with other IEEE compliant Layer-2 devices. DragonWave l2sw provides the basic bridging functionality and also offers advanced features such as RSTP/MSTP

2.1 Management Interface While many of the Quantum CLI commands address basic switch functionality, access to the layer 2 switch management interface is also provided. This section of the Horizon Quantum Product Manual, Volume 4, contains l2sw commands associated with the layer 2 switch management interface. For Quantum CLI commands, please refer to Volumes 1 and 2 of the Horizon Quantum Product Manual.

Use the CLI command l2sw to log into the layer 2 switch management interface. The commands that will be available to you will depend on your Quantum user level (Admin, NOC, or Super User). When logged on you will see the layer 2 switch prompt “l2sw#”. l2sw# The privileged EXEC mode is now available to the user. CLI command modes provide a detailed description of the various modes available.

The command prompt always displays the current mode.

CLI commands need not be fully typed. The abbreviated forms of CLI commands are also accepted by the DragonWave l2sw CLI, provided that they are unique. Example, commands like “configure terminal” can be entered as “c t” and "show spanning tree" can be entered as "sh sp".

CLI commands are case insensitive.

CLI commands will be successful only if the dependencies are satisfied for a particular command that is issued. The general dependency is that the module specific commands are available only when the respective module is ‘enabled’. Appropriate error messages will be displayed, if the dependencies are not satisfied.

Saving Switch Parameters 2.1.1Note that any system management and switch port configuration parameters are now captured in a separate management information base - l2swmib. Configuration settings relating to the following parameters are now saved in the l2swmib and are no longer part of the main mib:

• VLAN • Port characteristics • IPG • Network Management • Port Priority

To save these settings to flash memory requires the CLI command save l2swmib to be issued once all changes have been made. This is required regardless as to the status of the DragonWave l2switchFeature license group. This is in addition to the usual save mib command which is required to save other system parameters.

Blocked Commands 2.1.2In this release of DragonWave l2sw, there are some commands that may, under certain circumstances, be blocked. There are three types of blocked command:

1. a command that may be listed when issuing the “?” (see section 2.1.3), but which is not supported in the current release of DragonWave l2sw, will be blocked.

The system response on entering such a blocked command is: % Invalid Command

2. a valid command is sometimes blocked depending on what the configuration is applied to:

Example: All data ports’ physical characteristics are not user configurable. Changing the mtu for a dp port is blocked

2sw(config-if)# mtu 9000 %configuration prohibited

The system response on entering such a blocked command is: % configuration prohibited

All blocked commands in this category are interface commands, i.e. they are commands you use when configuring a particular interface, e,g. gi 0/6. The following table shows what commands are blocked on what interface.

Interface Command

Front Ports (gi 0/1 to gi 0/8)

Data Ports (gi 0/9 to gi 0/12)

CPU Port (gi 0/13) Port Channel

duplex Allowed Blocked Blocked N/A flowcontrol Allowed Blocked Blocked N/A hol Allowed Blocked Blocked N/A mtu Allowed Blocked Blocked Blocked negotiation Allowed Blocked Blocked N/A shutdown Allowed Blocked Blocked Blocked speed Allowed Blocked Blocked N/A

3. a valid command may be blocked if a conflicting situation exists

Example: If management vlan is configured as “any” with vlan 1, and port 1 is configured as an access port with vlan 1, then the user is prevented, or blocked, from changing the vlan of port 1 to be an access port with any other VLAN port. l2sw(config-vlan)# ports gigabitethernet 0/3 untagged gigabitethernet 0/3 % Member ports are different from management ports

The system response on entering such a blocked command varies, but does explain the conflicting situation.

Layer 2 Switch Feature 5


Context Sensitive Help 2.1.3DragonWave CLI framework offers context sensitive help; The user can type a question mark (?) anytime during a session to get help. The help can be invoked in several ways. It is not displayed as a whole and is available only for the specific token from where it is invoked.

Examples of possible scenarios are given below.

1. User keys in a character followed immediately by a question mark (?). This displays the current possible tokens without help string.

l2sw# sh?

show

2. User enters a keyword at the command prompt and enters a question mark (?) after hitting a space. This displays the next possible tokens along with the corresponding help string..

l2sw# show ?

debugging State of each debugging option

Some of the basic concepts implemented for the context sensitive help are:

1. The next possible tokens are listed only in the lexical order and not in the order as available in the syntax or command structure.

2. All possible tokens are listed along with the help string, even though the command is ambiguous. Any ambiguous command errors and value range errors are taken care of only during the execution of the command.

3. The help tokens provided within <> brackets denotes that the user should input values of specified format. For example, <string(32)> represents that the user should input a string of size varying from 1 to 32.

4. The help tokens provided within () brackets denotes that the user should input only the values represented. For example, (1-4094) represents that the user should input value within the mentioned range alone.

5. The format is directly provided as help token for some non-keyword such as MAC address. For example, aa:aa:aa:aa:aa:aa represents that a MAC address of this format should be provided.

6. Only the most commonly used format is provided as help token for some non keywords, but the command supports most of the valid formats.

7. The help token <CR> along with help string explaining the operation of the command is displayed, if the command can be executed at that point (errors are handled only during the execution).

CLI command modes 2.1.4The following table format lists the different CLI command modes. Depending on the CLI mode, l2sw prompt will be specific.

Command Mode Access Method Prompt Exit method

Privileged EXEC This is the initial mode to start a session

l2sw#

To return from the Privileged EXEC mode to Quantum CLI, type in exit.

Global Configuration The Privileged EXEC mode command configure terminal is used to enter the Global Configuration mode

l2sw(config)#

To exit to the Privileged EXEC mode the end command is used.

Config-VLAN The Global configuration mode command vlan vlan-id is used to enter the Config-VLAN mode.

l2sw(config-vlan)#

To exit to the Global Configuration mode the exit command is used and to exit to the Privileged EXEC mode the end command is used.

Privileged EXEC Mode 2.1.5When in a Quantum CLI session, if the user enters the CLI command “ l2sw”, the user will have access to the layer 2 switch at a user level comparable to that which s/he has for the Quantum (admin, NOC or Super User). The Privileged EXEC mode prompt is “l2sw#”.

Global Configuration Mode 2.1.6Global Configuration commands apply to features that affect the system as a whole, rather to any specific interface.

Interface Configuration Mode 2.1.7To enter into Interface configuration mode from the Global Configuration mode, interface <interface-type><interface-id> command is used. To exit to the global configuration mode the exit command is used and to exit to the privileged EXEC mode the end command is used.

2.1.7.1. Physical Interface Mode

The Physical Interface mode is used to perform interface specific operations. To return to the global configuration mode the exit command is used.

2.1.7.2. VLAN Interface Mode

The VLAN Interface mode is used to perform L3-IPVLAN specific operations. To return to the global configuration mode the exit command is used.



Config-VLAN Mode 2.1.8This mode is used to perform VLAN specific operations. To enter into Config-VLAN mode from the global configuration mode, vlan vlan-id command is used. To return to the global configuration mode the exit command is used.

2.1.8.1. MSTP Configuration mode

This mode is used to configure the MSTP specific parameters for the switch. The Global configuration mode command spanning tree mst configuration is used to enter the MSTP Configuration mode and. the prompt seen at this mode is l2sw (config-mst)#.

To return to the global configuration mode the exit command is used.

2.2 System Commands This section describes the commands used to manage access permissions, mode access and terminal configurations on ISS.

no interface {port-channel <integer (1-65535)> | tunnel <integer (0-128)> | <iftype> <ifnum> }

Syntax Description

port-channel<integer (1-65535)>

- Configures the port to be used by the host to configure the router. This value ranges between 1 and 65535.

The port channel identifier can be created or port channel related configuration can be done, only if the LA feature is enabled in the switch.

tunnel<integer (0-128)> - Configures the tunnel. This value ranges between 0

and 128. <iftype>

- Configures the specified type of interface. The interface

can be: • fastethernet – Officially referred to as 100BASE-T

standard. This is a version of LAN standard architecture that supports data transfer upto 100 Megabits per second.

• gigabitethernet – A version of LAN standard architecture that supports data transfer upto 1 Gigabit per second.

• extreme-ethernet – A version of Ethernet that supports data transfer upto 10 Gigabits per second. This Ethernet supports only full duplex links.

• i-lan / internal-lan – Internal LAN created on a bridge per IEEE 802.1ap.

• port-channel – Logical interface that represents an aggregator which contains several ports aggregated together.

DragonWave Inc. 14


<ifnum> Configures the specified interface identifier. This is a

unique value that represents the specific interface. This value is a combination of slot number and port number separated by a slash, for interface type other than i-lan and port-channel. For example: 0/1 represents that the slot number is 0 and port number is 1. Only i-lan or port-channel ID is provided, for interface types i-lan and port-channel. For example: 1 represents i-lan and port-channel ID.

Example l2sw# config terminal

l2sw(config)# interface gigabitethernet 0/5

l2sw(config-if)#

negotiation 2.3.3

This command enables auto-negotiation on the interface.

The no form of the command disables auto-negotiation on the interface.

The port in which auto-negotiation is enabled, negotiates with the other end for port properties like speed, duplexity and so one. The normal port uses the port property values configured by the administrator.

negotiation

no negotiation


Example l2sw(config-if)# negotiation



speed 2.3.4This command sets the speed of the interface. The no form of the command sets the speed of the interface to its default value.

speed { 10 | 100 | 1000 | 10000 | auto | nonegotiate}

no speed

Syntax Description

10

- Port runs at 10Mbps

100


1000


10000


auto

- Port automatically configures it’s speed based on the

peer switch. The switch negotiates with the device at the other end of the link for the speed setting and then forces the speed setting to the negotiated value.

nonegotiate

- Disable negotiation on the ports.

This feature has been included to adhere to the Industry Standard CLI syntax. This feature is currently not supported.


Defaults auto

Example l2sw(config-if)# speed 100

• The Gigabit Ethernet port speed can be configured to 10, 100, or 1000 Mbps

• This command cannot be executed to manually set values, if the port is automatically negotiating the link parameters with its peer. In that case, use the command no-negotiation to disable auto-negotiation feature.

Related Commands

• no negotiation - Disables auto-negotiation on the interface.

• duplex - Configures the duplex operation

Related Commands

• no negotiation - Disables auto-negotiation on the interface

• speed - Sets the speed of the interface

DragonWave Inc. 18


mtu frame size 2.3.9This command configures the maximum transmission unit frame size for the interface. The value ranges between 90 and 9216.

This value defines the largest PDU that can be passed by the interface without any need for fragmentation. This value is shown to the higher interface sub-layer and should not include size of the encapsulation or header added by the interface. This value represents the IP MTU over the interface, if IP is operating over the interface.

mtu <frame-size(90-9216)>

flowcontrol 2.3.10This command is used to set the send or receive flow-control value for an interface.

If flowcontrol send is on for a device and if it detects any congestion at its end, then it notifies the link partner or the remote device of the congestion by sending a pause frame.

If flowcontrol receive is on for the remote device and it receives a pause frame, then it stops sending any data packets. This prevents any loss of data packets during the congestion period.

PAUSE is a flow control mechanism that is implied on full duplex Ethernet link segments. The mechanism uses MAC control frames to carry the PAUSE commands.

flowcontrol { send | receive} { on | off | desired}

Syntax Description

send - Sets the interface to send flow control packets to a remote device

receive

- Sets the interface to receive flow control packets from a remote

device on

- If used with receive allows an interface to operate with the

attached device to send flow control packets

If used with send the interface sends flowcontrol packets to a remote device if the device supports it

off

- Turns-off the attached devices (when used with receive) or the

local ports (when used with send) ability to send flow-control packets to an interface or to a remote device respectively

desired - Allows a local port to operate with an attached device that is required to send flow control packets or that may send the control packets, when used with receive option.

Allows the local port to send administrative status to a remote device if the remote device supports it, when used with send option.




Defaults The default flow control for the interfaces are flowcontrol receive off flowcontrol send off

2.4 Spanning Tree Protocol (STP) STP is a link management protocol that provides path redundancy while preventing undesirable loops in the network that are created by multiple active paths between stations. To establish path redundancy, STP creates a tree that spans all of the switches in an extended network, forcing redundant paths into a standby or blocked state.

For an Ethernet network to function properly, only one active path should exist between two stations. Multiple active paths between stations in a bridged network can cause loops in which Ethernet frames can endlessly circulate. STP logically breaks such loops and prevents looping traffic from clogging the network. The dynamic control of the topology provides continued network operation in the presence of redundant or unintended looping paths.

The prompt for the global configuration mode is,

l2sw(config-switch)# spanning-tree mode rst

The STP functionality is realized in the network using one of the two following STPs:

• RSTP • MSTP

Note 1 - STP cannot be enabled on an Ethernet port that is not configured as part of the isolated port group IPG0.

RSTP 2.4.1DragonWave RSTP is an implementation of the IEEE 802.1D standard. It provides rapid recovery of connectivity following the failure of a bridge/bridge port or a LAN. It reduces the time to reconfigure the active topology of the network when physical topology or topology configuration parameters change. It provides increased availability of MAC service when there is a reconfiguration or failure of components in a bridged LAN. It can interoperate with legacy STP bridges without any change in the configuration.

MSTP 2.4.2DragonWave MSTP is an implementation of the IEEE 802.1s standard. It is used to configure spanning tree on per VLAN basis or multiple VLANs per spanning tree. It allows you to build several MST over VLAN trunks, and group or associate VLANs to spanning tree instances, so the topology of one instance is independent of the other instance. It provides multiple forwarding paths for data traffic and enables load balancing. It improves the overall network fault tolerance, as failure in one instance does not affect the other instances.

2.5 STP Commands Common for RSTP and MSTP

This section describes all spanning tree protocol related commands that are common for all kinds of STPs.

spanning-tree - Properties of an interface 2.5.1

This command configures the port related spanning tree information for all kinds of STPs.

The no form of this command resets the port related spanning tree information to its default value. The port related spanning tree information is changed to its default value even if the spanning tree mode is changed.

spanning-tree {cost <value(0-200000000)>|disable|link-type{point-to-point|shared}|portfast|port-priority <value(0-240)>}

DragonWave Inc. 36


no spanning-tree {cost |disable|link-type|portfast|port-priority}

Syntax Description

cost - Configures the port’s path cost value that contributes to the path cost of paths containing this particular port. The paths’ path cost is used during calculation of shortest path to reach the root. The path cost represents the distance between the root port and designated port. This value ranges between 1 and 200000000. The configured path cost is used, even if the dynamic pathcost calculation feature or LAGG speed feature is enabled. This configuration is not supported for the spanning tree mode pvrst.

disable - Disables the spanning tree operation on the port. The port does not take part in the execution of spanning tree operation for preventing undesirable loops in the network.

link-type - Configures the link status of the LAN segment attached to the port. The options available are:

1. point-to-point – The port is treated as if it is connected to a point-to-point link.

2. shared - The port is treated as if it is using a shared media connection.

portfast - Configures the portfast feature in the port. This feature

specifies that the port is connected to only one hosts and hence can rapidly transit to forwarding. This feature can cause temporary bridging loops, if hubs, concentrators, switches, bridges and so on are connected to this port. This feature takes effect only when the interface is shutdown.

port-priority - Configures the priority value assigned to the port. This value is used during port role selection process. This value ranges between 0 and 240. This value should be set in steps of 16, that is, you can set the value as 0, 16, 32, 48, and so on. This configuration is not supported for the spanning tree mode pvrst.

Mode Interface Configuration Mode (Physical Interface Mode)




Defaults cost - 200000 for all physical ports

199999 for port channels

disable - Spanning tree operation is enabled in the port.

link-type - The port is considered to have a point-to-point link if: • It is an aggregator and all of

its members can be aggregated.

• The MAC entity is configured for full duplex operation, either manually or through auto negotiation process (that is, negotiation mode is set as Auto)

Otherwise port is considered to have a shared media connection

portfast - Portfast is disabled.

port-priority - 128

Example l2sw(config-if)# spanning-tree cost 2200 l2sw(config-if)# spanning-tree link-type point-to-point l2sw(config-if)# spanning-tree portfast l2sw(config-if)# spanning-tree port-priority 32

spanning-tree guard 2.5.23This command configures the various PVRST guard features such as root guard, in a port.

The no form of this command resets the guard feature to its default value. spanning-tree guard {root | none | loop

no spanning-tree guard

Syntax Description

root - Enables root guard feature in the port. This feature prevents the port from becoming root port or blocked port. The port changes to the root-inconsistent state, if the port receives superior BPDUs. The port automatically reverts back to forwarding state, once the superior BPDUs are not received.

none - Disables both root and loop guard features in the port.

loop - Enables loop guard feature in the port. This feature changes the port to an inconsistent state if no BPDUs are received. Thus isolating the failure and letting spanning tree converge to a stable topology until the port starts receiving BPDUs again. This feature is currently not supported.

Mode Interface Configuration mode (Physical Interface Mode)


Defaults None (No PVRST guard feature is enabled).

Example l2sw(config-if)# spanning-tree guard root

• This command can be executed successfully, only if the spanning tree functionality is not shutdown in the switch. The type of spanning tree mode should be set as pvrst.

• The guard feature can be configured only on ports that are set as trunk port.

spanning-tree mst max-hops 2.6.1

This command configures the maximum number of hops permitted in the MSTP.

The no form of this command resets the maximum number of hops to its default value.

The number of hops represents the maximum number of switches that a packet can cross before it is dropped. The switch uses this value to avoid infinite looping of the packets, if it is elected as the root switch in the topology.

The root switch always transmits a BPDU with the maximum hop count value. The receiving switch decrements the value by one and propagates the BPDU with modified hop count value. The BPDU is discarded and the information held is aged out, when the count reaches 0.

This value ranges between 6 and 40.

spanning-tree mst max-hops <value(6-40)>

no spanning-tree mst max-hops


Defaults 20

Example l2sw(config)#spanning-tree mst max-hops 10

2.7 VLAN VLANs (Virtual LANs) can be viewed as a group of devices on different physical LAN segments which can communicate with each other as if they were all on the same physical LAN segment, that is, a network of computers that behave as if they are connected to the same wire even though they may actually be physically located on different segments of a LAN. VLANs are configured through software rather than hardware, which make them extremely flexible.

VLAN provides the following benefits for switched LANs:

• Improved administration efficiency

• Optimized Broadcast/Multicast Activity

• Enhanced network security

The prompt for the global configuration mode is,

l2sw(config-switch)# set vlan enable

The prompt for the VLAN configuration mode is,

l2sw(config-switch-vlan)# ports gigabitethernet 0/1 untagged gigabitethernet 0/1 forbidden gigabitethernet 0/2 name vl1

shutdown vlan 2.7.1

This command shuts down the VLAN switching feature in the switch and releases all resources allocated to the VLAN feature.

The no form of the command starts and enables VLAN switching feature in the switch. The resources required for the VLAN feature are also allocated to it.

The VLAN feature allows you to logically segment a shared media LAN for forming virtual workgroups.

shutdown vlan

no shutdown vlan


Defaults VLAN switching feature is started and enabled in the switch.

Example l2sw(config)# shutdown vlan

VLAN module can be shutdown, only if the GARP module is shutdown.

VLAN switching configuration is not allowed in the switch, if the base bridge mode is set as transparent bridging.

The PVID represents the VLAN ID that is to be assigned to untagged frames or priority-tagged received on the port. The PVID is used for port based VLAN type membership classification. This value ranges from 1 to 4094.

The PVID configuration done is used based on the acceptable frame type of the port. The packets are processed against PVID, if the packets accepted at ingress is not having a tag.

switchport pvid <vlan-id(1-4094)>

no switchport pvid


Defaults 1 (ID of default VLAN)

Example l2sw(config-if)# switchport pvid 3

• Only the IDs of the active VLAN can be used as PVIDs in the command.

• This command is applicable only for the port configured as switch port.

• The PVID cannot be configured for the port, if the base bridge mode is set as transparent bridging or the VLAN switching feature is shutdown in the switch.

Related Command

• switchport - Configures the port as switch port.


• vlan active - Activates a VLAN in the switch.

• switchport acceptable-frame-type - Configures the type of VLAN dependant BPDU frames such as GMRP BPDU, that the port should accept during the VLAN membership configuration.

switchport access vlan 2.7.14

This command configures the PVID (Port VLAN Identifier) on a port. The no form of this command sets the PVID to the default value on the port.

This command is a complete standardized implementation of the existing command and operates similar to that of the command switchport pvid. This feature has been included in adherence to the Industry Standard CLI syntax.

switchport access vlan <vlanid (1-4094)>

no switchport access vlan

Syntax Description

vlan-id - PVID value to be configured on the port.


Example l2sw(config-if)# switchport access vlan 3

• If the frame (untagged/priority tagged/customer VLAN tagged) is received on a "tunnel" port, then the default PVID associated with the port is used.

• If the received frame cannot be classified as MAC-based or port-and-protocol-based, then the PVID associated with the port is used.

• For ports in PBB bridge mode, PVID can be configured on CNP (Customer Network Port) and CBP (Customer Backbone Port).

• Usage is based on acceptable frame type of the port. Packets will be either dropped or accepted at ingress. Once a packet is accepted, if the packet is having a tag, it will be processed against that tag. Otherwise, the packet will be processed against PVID.

show vlan port config - Displays the VLAN related parameters specific for ports



switchport priority default 2.7.15

This command configures the default ingress user priority for a port.

The no form of the command resets the default ingress user priority for the port to its default value.

This priority is assigned to frames received on the port, that does not have a priority assigned to it. This priority value is useful only on media such as Ethernet, that does not support native user priority. This value ranges from 0 to 7. The value 0 represents the lowest priority and the value 7 represents the highest priority.

switchport priority default <priority value(0-7)>

no switchport priority default


Defaults 0

Example l2sw(config-if)# switchport priority default 5


• The default user priority cannot be configured for the port, if the base bridge mode is set as transparent bridging or the VLAN switching feature is shutdown in the switch.

DragonWave Inc. 130


no switchport mode

Syntax Description

access

- Configures the port as access port that accepts and sends

only untagged. This kind of port is added as a member to specific VLAN only and carries traffic only for the VLAN to which the port is assigned. The port can be set as access port, only if the following 3 conditions are met: • The GVRP is disabled for that port. • Acceptable frame type is set as “untagged AND priority”

tagged. • Port is a not a tagged member of any VLAN.

trunk

- Configures the port as trunk port that accepts and sends

only tagged frames. This kind of port is added as member of all existing VLANs and for any new VLAN created, and carries traffic for all VLANs. The trunk port accepts untagged frames too, if the acceptable frame type is set as all. The port can be set as trunk port, only if the port is not a member of untagged ports for any VLAN in the switch.

hybrid

- Configures the port as hybrid port that accepts and sends

both tagged and untagged frames.

private-vlan - Configures Pvlan for the specified VLAN switch port. promiscuous - Communicates with all interfaces, including the isolated and

community ports within a PVLAN. The function of the promiscuous port is to move traffic between ports in community or isolated VLANs.

host - Specifies the type of a port in private vlan domain. Untagged member port in a primary or secondary vlan • If a host port is a member port of an isolated VLAN,

traffic from the host port is sent only to the promiscuous port of the Private VLAN and the trunk port.

• If a host port is a member port of the community VLAN, traffic from the port can be sent only to other ports of the community VLAN , trunk port and promiscuous port of the private VLAN.

dynamic

- Dynamic Mode. This can be:

• auto – Interface converts the link to a trunk link.

• desirable – Interface actively attempts to convert the link to a trunk link.





Defaults hybrid

Example l2sw(config-if)# switchport mode access


• The VLAN port mode cannot be configured for the port, if the base bridge mode is set as transparent bridging or the VLAN switching feature is shutdown in the switch.

3.0 Ethernet Connectivity Fault Management (ECFM) IEEE 802.1ag and ITU-T Y.1731 standards define mechanisms that provide Ethernet Connectivity Fault Management (ECFM). The fault management mechanisms defined by Y.1731 are basically the same as those for 802.1ag, but with subtle differences in the concept of the management domain and its association. ITU-T Y.1731 also defines performance monitoring mechanisms.

ECFM comprises a number of fault management mechanisms that work together to help administrators debug Ethernet networks. These are:

• connectivity check message (CCM) • link trace message (LTM) • loopback message (LBM) • remote defect indication (RDI) • alarm indication signal (AIS – supported by Y.1731 only)

The Y.1731 performance monitoring mechanisms include: • frame loss measurement (LM) • frame delay measurement (DM) • throughput measurement

The Horizon Quantum supports the CCM, LTM, LBM, and RDI mechanisms of 802.1ag and Y.1731 mechanisms noted above. The AIS and performance monitoring mechanisms of Y.1731 are not supported. However Horizon Quantum will respond to DM messages.

ECFM is supported on all ports of the Horizon Quantum. The wireless side port is also considered as one of the ports and it is indexed as port 9 for ECFM.

Entering networking details of maintenance domains (MD), maintenance associations (MA), maintenance association intermediate points (MIP) and maintenance end points (MEP), into a database on various devices in an Ethernet network, allows operators to trace fault conditions throughout that network.

The Horizon Quantum is limited in the number of the above elements it can manage as follows:

• MD – 32 • MA – 32 per MD • MEP – 1024

NOTE: Only 32 MEPs are supported to work with 100ms CCM period. Any configurations beyond these limits are not blocked by the system, but they are not supported.

There are four steps to configuring ECFM. Each step comprises the issuing of a number of CLI “set” commands. Some of these commands must be entered in a specific order for the configuration to be successful.

Section 3.1 shows the basic steps involved in configuring ECFM on the Horizon Quantum.

Section 3.2 has configuration examples that show, in more detail, how to configure the Horizon Quantum for ECFM.

Section 3.3 contains all the CLI commands associated with ECFM, with a brief explanation of their function.

Note that ECFM uses a special MAC address that the network system discovers through connectivity check messages sent out by the CE’s. This allows Loopback and Linktrace activities to be performed. Since the ECFM MAC address is auto discovered by the network system, there is no need to configure this address in the Horizon Quantum. However, if you wish to determine what the Horizon Quantum ECFM MAC address is, use the CLI command get ecfm maintenance-point local.

Note that the ECFM flow mapping feature (see Section Error! Reference source not found.) is overridden when ECFM is enabled on the node.

Sequence: ecfm traceroute ethernet mpid <id> {domain <domain-name(1..20)> | level <level-id(0-7)>} [vlan <vlan-id(1-4094)>] [time-to-live <ttl-value(1-255)> Where mpid <id> identifies the MEP identifier of the remote MEP. Other parameters are same as those in the command - ecfm ping ethernet mac. The system responds: (Example) ->ecfm traceroute ethernet mpid 41 level 4 Traceroute to Macaddress 00:10:94:00:00:11 in domain MD_level_4 at level 4 with vlanId 0 ------------------------------------------------------------------------- Hops Host Ingress MAC Ingress Action Relay Action Next Host Egress MAC Egress Action Fwd Status ------------------------------------------------------------------------- 1 00:01:00:07:58:80:a3:37 - - RlyFDB 00:00:00:10:94:00:00:16 00:10:94:00:00:16 EgrOK Forwarded 2 00:00:00:10:94:00:00:16 - - RlyHit

ecfm frame delay Start or Stop the ecfm delay measurement calculations. Sequence: ecfm frame delay [start | stop] type {one-way | two-way } level <level-id(0-7)> [vlan <vlan-id(0-7)>] [switchport <port-num>] [direction {inward | outward}]{mepid <mpid(1-8191)> | mac <aa:aa:aa:aa:aa:aa>} [count<num_of_observations(1-8192)>] [interval <milliseconds(10-10000)>] [deadline <seconds(1-172800)>] [switchname <context_name>]] press Enter Where start | stop is to start ot stop frame delay message type { two-way } identifies the two-way performance measurement level <level-id(0-7)> identifies the domain’s level vlan <vlan-id(0-7)> identifies the service’s vlan id switchport <port-num> identifies the port number direction {inward | outward} specifies the direction of the local MEP. The default is “outward”. mepid <mpid(1-8191)> identifies the identifier of the local MEP mac <aa:aa:aa:aa:aa:aa> identifies the target’s Mac address count <num_of_observations(1-8192)> specifies the total number of frame delay messages. interval <milliseconds(10-10000)> specifies the interval of frame delay message deadline <seconds(1-172800)> identifies the expired time of the frame delay message. Note: Mac Address of the MEP with specified target “mpid” must be learned prior to the execution of the command. Run the command ‘get ecfm frame delay buffer’ to see the result of frame delay measurement, Example: ->ecfm frame delay start type two-way level 7 vlan 1007 mepid 71 count 5 interval 2000 ->get ecfm frame delay buffer Interface : gigabitethernet 0/1 MEP-ID : 222 Level : 2 VLAN-ID : 1002 peer mac-address frame-delay IFDV FDV 00:07:58:00:a3:c7 240.0ms 0.000ms 0.00ms 00:07:58:00:a3:c7 160.0ms 0.000ms 0.00ms --- 00:07:58:00:a3:37 frame delay statistics --- measurement timestamp = 10 Jul 2078 10:50:1, packets sent = 2, packets received = 2, frame delay average = 200.0ms, IFDV average = 0.000ms, FDV average = 0.000ms
