1) Creating NEs in Batches

When the U2000 communicates properly with a GNE, you can search for all NEs that communicate with the GNE by using the IP address of the GNE or the network segment to which the IP address is associated. Then, you can create NEs in batches. This method is quicker and more accurate than manual creation.

Procedure

Choose File > Discovery > NE from the main menu.

Click the Transport NE Search tab.

Optional: Enter the network segment or IP addresses NEs to search for the NEs.

Click Add and the Input Search Domain dialog box is displayed.

Set Address type to IP Address Range of GNE, IP Address of GNE and enter Search Address, User Name, and Password. Then, click OK.

NOTE: You can repeat Steps a through b to add more search domains. You can delete the system default search domain.

If you use IP address to search for NEs: Usually, the broadcast function is disabled on the routers on a network, to avoid network

broadcast storm. Therefore, by using the IP Address Range of GNE method, only the NEs in the same network segment can be searched out.

To search the network segments across routers, the IP Address of GNE method is recommended. Through a gateway NE, you can search out the NEs in the network segment of the gateway NE.

Optional: If you fail to enter a network segment correctly, enable IP auto discovery and enter the User Name and Password of the NEs.

NOTE:

After enabling IP auto discovery, you can obtain the IP address of the GNE and search out all the NEs related to the GNE.

If the U2000 and an gateway NE are connected through a router, you need to create an NE by using the IP address of the gateway NE.

In the Search for NE area, perform the following operations:


Page 3 of 42

Select Create device after search, enter the NE User and Password.

NOTE:

The default NE user is root. The default password is password.

Select Upload after create. The data related to the NEs are uploaded to the U2000 after the NEs are created.

NOTE:

You can select all options in the Search for NE area to search for NEs, create NEs, and upload the NE data at a time.

Click Next and the Result area is displayed.

2) Creating a Single NE

After the NE is created, you can use the U2000 to manage the NE. Although creating a single NE is not as fast and exact as creating NEs in batches, you can use this method regardless of whether the data is configured on the NE or not.

Prerequisites

• You must be an NM user with "Transmission Network NM operator" authority or higher.

• The NE Explorer instance of the NEs must be created.

Context

First create a GNE, and then create a non-gateway NE.

If the NE is not created properly or the communication between the NE and the U2000 is abnormal, the NE is displayed in gray color.

15 ) Configuration Example of a UNI-NNI CES Service

Case Description

This section describes the UNI-NNI application scenarios of the CES service, including the networking diagram and service planning.UNI-NNI CES

Networking and Requirement

Between BTS and BSC, the CES service is transported through the PTN equipment, as shown in Figure 1. Two CES services are available between BTS and BSC that are connected to NE1. NE1 uses the OptiX PTN 1900 to access the services from the base stations, and NE2, NE3, NE4 and NE5 use the OptiX PTN 3900, NE6 uses the OptiX PTN 1900. Tunnels should be configured between NE1 and NE3.

If the service requires high network security, configure the MPLS APS protection to ensure service transmission.

• Working tunnel: NE1-NE2-NE3. NE2 is a transit node.

• Protection tunnel: NE1-NE6-NE5-NE4-NE3. NE6, NE5, and NE4 are transit nodes. When the working tunnel becomes faulty, the service on it is switched to the protection tunnel for protection.

Figure 1 Networking diagram of the CES service

Figure 2 shows the planning details of boards on the NE and interfaces on the boards.

17 ) Configuring the E-Line Service Interface

This section describes the types of interfaces that can carry E-Line services and how to configure an interface when it is to be used for carrying an E-Line service.

Prerequisite


Context

When used as an UNI, an Ethernet interface can access Ethernet services and works in Layer 2 mode. Table 1 lists the types of E-Line service interfaces and application scenarios of them.

Procedure

• Configure an interface of the null encapsulation type.

1. In the NE Explorer, select an NE and choose Configuration > Interface Management > Ethernet Interface from the Function Tree.

2. Click the General Attributes tab, and select the interface to be configured.

3. Set the Enable Port to Enabled, Port Mode to Layer 2, and the Encapsulation Type to Null. And set the Working Mode and Max Frame according to networking planning.

4. Click Apply.

• Configure an interface of the C-Tag (802.1Q) encapsulation type.

1. Click the General Attributes tab, and select the interface to be configured.


Page 37 of 42

2. Set the Enable Port to Enabled, Port Mode to Layer 2, and the Encapsulation Type to 802.1Q. And set the Working Mode and Max Frame according to networking planning.

3. Click Apply.

4. Click Layer 2 Attributes tab, and select the interface to be configured. Set the Tag attribute according to the service packets. And click Apply.

5. Optional: Set the Default VLAN ID according to the network planning, and click Apply.

18 ) Creating a UNI-UNI E-Line Service on a Per-NE Basis

A UNI-UNI E-Line service indicates that users can be interconnected through equipment. The Ethernet data packets do not pass the network side, but are transparently transmitted at the user side.

Prerequisite

If a port need be exclusively used, disable the DCN function of the port that carries the service.

Procedure

1. In the NE Explorer, select an NE and choose Configuration > Ethernet Service Management > E-Line Service from Function Tree.


Page 38 of 42

2. Click the UNI tab and click New. The New E-Line Service dialog box is displayed.

19 ) Creating a UNI-NNI E-Line Service Carried by a Port

The service is accessed at the user side, and transported to one port at the network side for carrying. In this way, user data can be transparently transmitted in a point-to-point manner. In this way, this port is exclusively used.

Prerequisite


If a port need be exclusively used, disable the DCN function of the port that carries the service. For details, see Enabling the Port DCN.

Procedure

1. Select the NE in the NE Explorer. Choose Configuration > Ethernet Service Management > E-Line Service from Function Tree.


Page 39 of 42


20 ) Creating a UNI-NNI E-Line Service Carried by a PW on a Per-NE Basis

The service is accessed at the user side, and transported to one PW at the network side for carrying. In this way, user data can be transparently transmitted in a point-to-point manner. For such a application, create a UNI-NNI E-Line service carried by a PW.

Prerequisite

If the service need be carried by an MPLS Tunnel, you must configure a tunnel first..

Procedure

1. Select the NE in the NE Explorer. Choose Configuration > Ethernet Service Management > E-Line Service from Function Tree.


Page 40 of 42


3. Set parameters in the dialog box.


Page 41 of 42

4. Click Configure PW. The Configure PW dialog box is displayed. In the PW General Attributes tab, set PW-related parameters.

NOTE: PW Type can be set to Ethernet or Ethernet Tagged Mode.

• Ethernet: The original C/SVlan tag of user packets is encapsulated in a PW without any change and then is transparently transmitted to the downstream stations.

• Ethernet Tagged Mode: A VLAN tag is stuck to user packets. To stick the VLAN tag, set Request VLAN in Advanced Attributes.

Tunnel selection mode can be set to Manually or Auto Select. • Manually: In this mode, you need to manually select a created tunnel.

• Auto Select: In this mode, the equipment automatically select a matched tunnel according to the specified tunnel selection policy and opposite LSR ID.


Page 42 of 42

5. Optional: Click the Tunnel Selection tab and select the preferred type of tunnels that carry the service.

Then, click to move the type to the front.

NOTE:

In the tunnel type list, the top tunnel type is the most preferred and the bottom tunnel type is the least preferred. When the more preferred tunnels are insufficient, the less preferred tunnels are selected.

6. In the QoS tab, set the parameters related to PW QoS according to network planning.

NOTE: • In the PW Ingress direction, Bandwidth Limit can be set to Enabled. In this case, you can set

CIR(Kbit/s) and PIR(Kbit/s) for the PW, or you can also select a proper QoS policy in Policy. Before selecting a policy, you need to create a policy.

• In the PW Ingress direction, a PW policy can be set. You can select a proper PW policy from the created PW policies.

• In the PW Ingress direction, EXP can be set to a value in the range of 0 to 7. "0" indicates the lowest priority and "7" indicates the highest priority.

• In the PW Egress direction, you can set the LSP mode.

7. In the Advanced Attributes tab, set the parameters related to the PW control word. To conduct a PW ping test, set Control Word to Preferred Use.

8. Click OK to finish the PW-related settings and PW attribute settings.

9. Click OK to finish the creation.
