To create and run a CFM link trace OAM diagnostic test from the STM

Steps

Note: The maximum number of continuous CFM link trace tests that can be executed is 300, provided that the SAA packet per second rate of 200 pps is not exceeded. The total number of continuous tests must share this maximum rate of 200 pps. However, it is recommended that the number of continuous CFM link trace tests executed be kept well below the maximum allowed limit.

You can also run this test contextually for VPLS, Epipe, and Composite services. See To configure and run OAM tests contextually for more information.

 
1 

Choose Tools→Service Test Manager (STM) from the NFM-P main menu. The Service Test Manager form opens.

2 

Click Create and choose Ethernet CFM→CFM Link Trace. The CFM Link Trace (Create) form opens.

3 

Configure the required parameters.

If you enable the NE Schedulable parameter, two additional tabs are displayed for the form: Test Parameters and Results Configuration.

4 

Select a global MEG in the Test Object panel.

5 

Select an originating MEP in the Test Object panel.

Note: MEPs can be added to services automatically or manually. If no MEPs are listed when you perform this step, see Ethernet CFM for information about how to configure a MEP that is required for this step.

6 

In the MEP Transmit Information panel, choose one of the following for the service destination test endpoint:

  1. Select a MEP, MIP, or Unmanaged MEP for the Target MAC Address parameter.

    Note: You must select a Maintenance Entity Group ID and Originating MEP prior to configuring this parameter for the Select buttons to function.

    Note: The MIP selection is not supported for OmniSwitch NEs.

  2. Click the Enable Target MEP ID checkbox if you want to specify a remote Maintenance Entity Point ID (MEP ID) endpoint.

    Note: With both options, you have the choice to either enter a value manually for the Target MEP ID or Target MAC Address parameter or use the selected value.

7 

If you enabled the NE Schedulable parameter in Step 3 , go to Step 8 . Otherwise, configure the MEP Transmit LBM Information parameters.

8 

Click on the Test Parameters tab and configure the REQUIRED parameters.

The Probe History parameter is only configurable when the NE Schedulable parameter is enabled.

9 

Click on the Results Configuration tab and configure the required parameters.

The Trap Generation parameter is only configurable when the Accounting Files parameter is disabled.

The Test Result Storage parameter is only configurable when the Accounting Files parameter is enabled.

10 

Save the changes and close the form.

11 

To run the OAM diagnostic test and view the results, perform To run one or more OAM diagnostic tests from the STM and view the test results . See To interpret OAM diagnostic test results on the STM for information about how to interpret the test results.
