To configure an Epipe, Apipe, or Cpipe as a test service for MPLS-TP service tunnels

Preliminary considerations

Perform this procedure to create a site on a VLL Epipe, Apipe, or Cpipe service that is used exclusively for carrying test traffic for MPLS-TP service tunnels.

The admin lock test can be configured on a spoke SDP binding that is bound to a VLL Epipe, Apipe, Cpipe, and spoke termination on VPLS.

Consider the following:

  • an MPLS-TP service tunnel must be used in the SDP binding, and the Control Word parameter on the Pseudowire OAM tab of the SDP binding must be set to Preferred

  • the Control Channel Status parameter on the Control Channel tab of the spoke SDP binding must be set to Disabled

  • a PW path must be created; see To configure an MPLS-TP static pseudowire on a VLL spoke SDP binding

  • an ICB SDP binding must not be created on an endpoint

  • no other service throughput configuration can exist on the site

  • for Apipe and Cpipe services, the VC Type of the service and the test service must match

Steps
Create a test service site
 

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


Create a VLL by clicking Create→VLL→Epipe|Apipe|Cpipe, or choose a VLL Epipe, Apipe, or Cpipe and click Properties. The Epipe|Apipe|Cpipe Service (Create|Edit) form opens.


If you are creating a service, configure the required general parameters.


On the navigation tree, right-click on the Sites icon and choose Create Epipe|Apipe|Cpipe Site. The Select Network Elements form opens.


Choose a site. The site you choose is also a service site on the host service of the throughput configuration you are configuring in Step 12 .


Click OK. The VLL Site (Create) form opens.


Configure the required general parameters.


Set the VLL Site Type to Terminating.


Enable the Test Service parameter .

Note: You must only create one site for a test service. This site defines a SAP that is the ingress and egress for test traffic.

The Test Service parameter is configurable only during site creation.

Save the changes and close the form.


Configure service throughput on the host service
 
11 

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


12 

Choose the VLL Epipe, Apipe, or Cpipe on which you want to configure the service throughput and click Properties. The Epipe|Apipe|Cpipe Service (Edit) form opens.


13 

On the Epipe|Apipe|Cpipe Service (Edit) form of the host service, click on the Throughput Configuration tab and click Create. The Service Throughput Configuration form opens.

Note: Alternatively, you can choose a service throughput-capable service from the Manage Services form, click on the Throughput Configuration button, and choose Create from the contextual menu.


14 

Configure the ID and Description parameters.


15 

Set the Test Method parameter to MPLS-TP Lock Instruct Function.


Configure the Admin Lock test
 
16 

A spoke SDP binding is administratively locked by locking the host service. Test traffic is injected into the spoke SDP binding using a test SAP, defined within the test service you created in Step 9 . When the admin lock is configured on a spoke SDP binding and a test service ID is specified, all of the traffic is forwarded to and from a SAP defined in the separate test service, which must be compatible with the spoke SDP binding. Traffic to and from the original SAP is dropped.

In the Traffic Test Entry panel, select a site on the host service. The Site ID is the site on which you are configuring the admin lock and the same site that you configured on the test service in Step 9 . The Admin Lock panel appears.


17 

In the Admin Lock panel, select the spoke SDP binding to lock on the host site you selected in Step 16 .


18 

In the Test Service panel in the Admin Lock panel, select the test service site you created in Step 5 to Step 10 .


Configure the Loopback test
 
19 

If a loopback is configured on a spoke SDP binding, all traffic on the ingress direction of the spoke SDP binding and associated with the ingress VC-label is forwarded to the egress direction of the spoke SDP binding. The terminating site with the loopback configured to send test traffic back to the SDP binding you selected in Step 17 is automatically selected.

In the Traffic Test Destination panel, you can clear the selection or manually select the terminating, or destination, site.


20 

In the Loopback panel, the spoke SDP binding on which you are configuring the loopback test is automatically selected. You can clear the selection or manually select an SDP binding.


21 

Save the changes and close the form.

Note: A site can only be used in one throughput configuration at a time. If a throughput configuration exists that uses a site as either a source or a destination, that site cannot be used in another throughput configuration.
