Configuring a PWE3 Service

Configuring a PWE3 Service

Some pseudo wire emulation edge-to-edge (PWE3) services are equipped with PW automatic protection switching (APS) while the others are not. This topic describes the detailed procedure for configuring a PWE3 service without PW APS. For the procedure for configuring a PWE3 service with PW APS, this topic only describes the difference from the procedure for configuring a PWE3 service without PW APS.

Configuring a PWE3 Service Without PW APS

This topic describes how to configure a pseudo wire emulation edge-to-edge (PWE3) service without PW automatic protection switching (APS).

Prerequisites

Procedure

  1. From the main menu of the U2000, choose Service > PWE3 Service > Create PWE3 Service. The Create PWE3 Service window is displayed.

  2. In the Create PWE3 Service window, set the basic attributes. For details, see E-Line Service Parameters (Configuration in End-to-End Mode).

    NOTE:
    • Services can be configured using a service template. The user can select a template from the Service Template drop-down list or create a template.
    • Set Service Type to ETH.

  3. Click Configure Source and Sink to configure the source and sink nodes.

  4. Select the desired NE. In the pane on the right, select the board and port that accept services and configure VLAN information for them. Click Add Node to configure the source node.

  5. Repeat 4 to add and configure the sink node and click OK.

    NOTE:

    The value of the VLAN ID of source node and sink node must be same.

  6. Configure MPLS-TP OAM for the PW.
    1. Click Detail, and select Advanced Attribute tab. Click MPLS-TP OAM(Y.1731).... The Configuration MPLS-TP OAM dialog box is displayed.
    2. In the dialog box, click Add, set OAM Status of the MEP and RMEP to Enable, and click OK.

    NOTE:
    If the MPLS-TP OAM function has not been enabled when you create the PWE3 service, you can enable the function after the service is configured. The operation procedure is as follows:
    1. In the Manage PWE3 Service window, right-click the desired PWE3 service and choose PW OAM > Configure MPLS-TP OAM from the shortcut menu.
    2. In the displayed Configuration MPLS-TP OAM dialog box, click Add, set OAM Status of the MEP and RMEP to Enable, and click OK.
    3. Right-click the desired PWE3 service again and choose PW OAM > Enable MPLS-TP OAM from the shortcut menu.

  7. Specify the tunnel that forwards PWs. Select the desired PW that has been created, double-click the Forward Tunnel column and click . The Select Tunnel window is displayed. Specify the tunnel that forwards PWs and click OK.

    NOTE:

    Parameters such as PW ID, Forward Label, and Reverse Label can use the automatically assigned values or be specified based on the service plan.

    If you want to configure alarm-related data, select the ETH OAM CC check box in the lower left corner to enable the regular OAM CC function for the equipment.





  8. Click OK or Apply on the lower right of the window to complete PWE3 service configuration.



  9. In the Operation Result dialog box, click Browse Trail to view the newly created PWE3 service.

  10. Perform a loopback (LB) test to check the bidirectional connectivity of the PWE3 service as follows: In the PWE3 Service Management window, right-click the PWE3 service and choose Ethernet OAM > LB Test.
  11. In the LB Test dialog box that is displayed, select the PWE3 service and click Run.

Configuring a PWE3 Service with PW APS

The procedures for configuring a pseudo wire emulation edge-to-edge (PWE3) service with PW automatic protection switching (APS) is similar to that for configuring a PWE3 service without PW APS. The difference is that PW APS must be configured. This topic only describes the parameters related to PW APS and the operations that need to be added compared with the creation of a PWE3 service without PW APS.

Prerequisites

Precautions

  • MPLS tunnel APS and PW APS are mutually exclusively.
  • The MPLS-TP OAM function must be configured and enabled for PWE3 services with protection. Otherwise, the service will fail to be deployed.

Procedure

  1. From the main menu of the U2000, choose Service > PWE3 Service > Create PWE3 Service. The Create PWE3 Service window is displayed.

  2. Set the basic information about the PWE3 service in the same way as configuring a PWE3 service without PW APS. In addition, ensure that Protection Type has been set to PW APS Protection.

  3. Specify the tunnel that forwards the working PW and the tunnel that forwards the protection PW and click Single Source and Single Sink in the Node List area.

  4. The other operations are the same as those for configuring a PWE3 service without PW APS protection. For details, see 3 in Configuring a PWE3 Service Without PW APS.
