To configure an Ethernet tunnel

Purpose

Use this procedure to configure an Ethernet tunnel. Before you can create an Ethernet tunnel, you must configure an Ethernet tunnel endpoint. See To configure an Ethernet tunnel endpoint .

Steps
 

Choose Manage→Service Tunnels from the NFM-P main menu. The Manage Service Tunnels form opens.


Click Create→Ethernet Tunnel or select an existing Ethernet tunnel and click Properties. The Ethernet Tunnel (Create|Edit) form opens.


Configure the required parameters.

The Access Adapt QoS, Enable Per Forwarding Path Ingress Queue, and Operational Path Endpoint Threshold parameters are only displayed when the Protection Type parameter is set to Load Sharing.


Automatically configure a CFM MEG on an Ethernet tunnel path and MEPs for each Ethernet tunnel path endpoint.

Perform the following steps:

  1. Configure the parameters in the Path CFM Defaults panel.

  2. Select a maintenance domain.

    Note:

    The configuration performed here when creating an Ethernet tunnel object cascades to each Ethernet tunnel path that is subsequently configured.


Click on the Apply button. The Ethernet Tunnel form refreshes with additional tabs displayed.


Click on the Components tab.


Right-click on the Tunnel Endpoints object and choose one of the following:

  1. Create Ethernet Tunnel Endpoint.

    Perform the following steps:

    1. See To configure an Ethernet tunnel endpoint to create an Ethernet Tunnel Endpoint. The endpoint will be listed as Endpoint A on the Ethernet Tunnel form in the Tunnel Endpoints Section.

      Note:

      The parameter values specified in Step 3 are automatically applied in the Ethernet Endpoint form when creating an endpoint.

    2. Repeat 1 to create Endpoint B.

  2. Add Existing Endpoint. The Select Endpoints form opens.

    Perform the following steps:

    1. Select an endpoint and close the form.

      The endpoint is listed as Endpoint A on the Ethernet Tunnel form in the Tunnel Endpoints Section.

    2. Repeat 1 to select Endpoint B.

      Note:

      The parameter values specified in Step 3 are not automatically applied to the selected Ethernet endpoint.


Right click on the Paths object and choose Create Ethernet Path. The Ethernet Path (Create) form opens.


Configure the required parameters.


10 

Click on the Endpoints tab. Perform one of the following:

  1. Manually configure the required parameters for endpoints A and B.

    A path endpoint cannot be administratively enabled if one of the following is true:

    • An operationally up same-fate SAP on the Ethernet tunnel endpoint does not have a tag configured for the path endpoint.

    • The Control Tag (Outer Encapsulation Value), Control Tag (Inner Encapsulation Value), and Member Port parameters are not configured.

  2. Select existing path endpoints for endpoints A and B. The endpoint parameters are automatically populated.


11 

Click on the Intermediate Services tab to view and specify the intermediate services for the Ethernet path. The services that you add to the list (or that already appear there) are in the order of proceeding from Endpoint A to Endpoint B. Perform the following to add an intermediate service:

Perform the following steps:

  1. Click Create. The Select Service form opens.

  2. Click on the Search button to display a list of intermediate services available to include in this path. Only VLL services can be included.

  3. Select the required service and click OK.

    The NFM-P does not perform a validation to confirm whether the selected service is actually along the path between the two path endpoints.

    If you have an intermediate service highlighted in the list and want to add another service immediately above it, click on the Insert Component button rather than the Create button. The Create button places an additional service at the bottom of the list, whereas the Insert Component button places it directly above a highlighted service.

    You can change the ordering of intermediate services in the list by selecting a particular service and using the Move Up or Move Down buttons.


12 

Click on the CFM Continuity Check tab to configure a CFM Continuity Check test for each path.

You must complete the following steps before selecting a test:


13 

In the CFM Test panel, select a CFM test.


14 

Perform one of the following:

  1. Perform one of the MEP auto creation functions:

    • Click Run Continuity Check Protocol to create maintenance associations and local and remote MEPs. Any existing remote MEPs that do not match the local MEPs are deleted. MEPs are turned up and CCM messages are enabled, and the control MEP property is set on the MEPs.

    • Click Create MEPs to create local MEPs. Any existing remote MEPs that do not match the local MEPs are deleted.

  2. Continue to Step 15 . Perform the Run Continuity Check Protocol or Create MEPs function at a later date.


15 

If required, click on the MEP tab to display the MEP form and select the check box to configure the Control MEP parameter.


16 

Save your changes and close the form.


17 

If the Protection Type parameter was set to G8031 1:1 in Step 3 , repeat Step 8 to  Step 16 for the other path.

If the Protection Type parameter was set to Load Sharing in Step 3 , repeat Step 8 to Step 16 for all paths.


18 

Click Apply. The Path Id, Operational State, and CC Protocol State parameters are updated and the path endpoints with this specific configuration are sent to the NEs.

The CC protocol state appears under the global path (in the navigation tree and on the CFM Continuity Check form). The CC protocol state displays the state of the continuity check protocol running between the MEPs of the two endpoints of the path.


19 

Save your changes and close the form.
