To configure and run OAM tests contextually

Reference

A number of the OAM diagnostic tests for objects and services described in this chapter can be contextually configured and executed from various entry points in the GUI. Specifically, VPLS, VPRN, Epipe, and Composite services, in addition to SAPs (access interfaces), SDP tunnels, SDP bindings, and LSPs can all be tested contextually. All of the tests are available in both Quick and Scheduled runs. Some test types also support a continuous run option. Scheduled tests use SNMP and continuous tests use accounting.

Contextual test creation and execution is available from:

  • Service topology maps and flat maps (for Composite services)

  • Sites and Interfaces tabs within a service properties form

  • Service Tree within a service properties form

  • Manage Service Tunnels form

  • Applicable Manage LSP forms

This procedure is applicable to all of these access modes, since the contextual test forms that are opened are the same, regardless of the access mode you use.

Contextual tests can be created between selected service sites or between or on specific entities. The tests are accessed by selecting single or multiple entities, then right-clicking and choosing Run OAM Tests.

Refer to the following procedures for additional detailed information on configuring the tests using the STM, if required:

Refer also to Working with Ethernet CFM objects in Chapter 4, Topology map management and To use OAM diagnostic functions on service topology and composite service flat topology maps for additional information on accessing OAM functionality from a service topology view.

Refer to the following service chapters for additional information, if required:

Additional procedural points:

  • To test SAPs, the SAPs must be operationally Up.

  • If you select SAPs or sites with resources such as Global MEGs and MEPs already present, you can utilize these objects and run the tests on top of them.

  • To test SDP bindings, the bindings must be operationally Up. The following types are supported:

    1. Regular Spoke SDP Bindings on VPLS, MVPLS, and Epipe services

    2. Regular Spoke SDP Bindings with source interfaces on VPRN services

    3. Mesh SDP Bindings on VPLS and MVPLS with V-sites and B-sites

    4. Static Spoke SDP Bindings on VPLS

    5. Spoke FEC 128 on Epipe services. Testing these types is only available from the table or tree view. The topology view is not supported.

  • Contextually-created test policies cannot be used to create regular test suites. When a contextually-created test suite is deleted, the associated test policy is also deleted.

  • Contextually-created OAM tests cannot be created between VPLS B-L2 Access Interfaces.

  • Contextually-created OAM tests cannot be created between Epipe sites.

  • For non-CFM entities, multiple OAM Context windows can be opened to run tests on different entities at the same time.

Steps

To demonstrate the contextual OAM configuration and execution workflow generally, this procedure covers the testing of two SAPs or sites as examples. Testing different entities follows the same basic process. The procedure assumes that you have already accessed either a service form or service topology view.

 
1 

Perform one of the following:

  1. Select two or more SAPs and right click on one of them.

  2. Select two or more sites and right click on one of them.

2 

Select Run OAM Tests from the contextual menu. The OAM Contextual Test form opens.

3 

Configure the OAM Test Type parameter for the type of test you want to run.

4 

Configure the Test Level and Number of Test Probes, as applicable.

5 

Configure and run one of the following test execution modes:

  1. Quick Run. Go to Step 6 .

  2. Scheduled Run. Go to Step 14 .

  3. Continuous Run. Go to Step 26 .

Quick Run tests
 
6 

Configure the Test Execution Mode for Quick Run.

Quick Run tests provide a one-time immediate test result.

7 

Click Execute to run the test.

Note: When you execute a test, all required test resources are automatically created by NFM-P. After the test has been executed, the created test resources are automatically deleted. Pre-existing resources that were used for the test are not deleted.

8 

To view the test results, click on the Quick Run Results tab and select an entry.

9 

Click Properties. The One Time Validation Result form opens. Results for each of the selected test objects are available in the Results tab.

Note: The test results are archived for future reference.

10 

Close the form.

11 

Click the SAPs or Sites tab to view the objects you chose to run the test. Click View Service to open the property form of the service associated with the selected objects.

12 

Click the Test Generation Log tab to view any error messages generated by the test.

13 

Close the form.

Scheduled Run tests
 
14 

Configure the Test Execution Mode for Scheduled Run.

15 

Enter a Test Suite Name. This name will be used for the automatically-created test suite required for the test. The created test suite can be viewed in the STM after test execution, if required.

16 

Click Select for the Test Suite Scheduler and perform one of the following in the Select OAM Context Schedules form:

  1. Select an existing schedule form and go to Step 17.

  2. Click Create and perform the following:

    1. Configure the required parameters in the NFM-P Schedule (Create) form.

      Note:

      CFM scheduled tests do not support a schedule with a frequency less than per minute.

    2. Click OK. The NFM-P Schedule (Create) form closes.

    3. Click Select for the Test Suite Scheduler and select the newly-created schedule.

17 

Click Execute. Tests will be executed as scheduled and the progress bar shows the current test status.

18 

To view the test results, click on the Test Suite Results tab and select an entry.

19 

Click Properties. The Test Suite Result form opens. General information regarding the test suite results is provided.

20 

To view individual test results, select an entry in the Results tab and click Properties. The Test Result form opens. Review the test results.

21 

To view the details of the test suite created for the test, click Test Suite View at the lower left-hand corner of the form. The OAM Contextual Test form closes and the Test Suite (Edit) form opens.

You can also view the SAPs or sites you selected for the test in the Contextual Tested Entity tab of the Test Suite (Edit) form.

22 

Close the Test Suite (Edit) form.

23 

Click the SAPs or Sites tab to view the objects you chose to run the scheduled test. Click View Service to open the property form of the service associated with the selected objects.

24 

Click the Test Generation Log tab to view any error messages generated by the test.

25 

Close the forms.

Continuous Run tests
 
26 

Configure the Test Execution Mode for Continuous Run.

Continuous Run tests are accounting policy based tests.

27 

Enter a Test Suite Name. This name will be used for the automatically-created test suite required for the test. The created test suite can be viewed in the STM after test execution, if required.

28 

Click Execute. Tests will be run at 15-minute intervals and the progress bar shows the current test status.

29 

To view the test results, click on the Test Suite Results tab and select an entry. If the continuously run test has yet not been run, its Status in the Test Suite Results tab shows as Request Sent.

30 

Click Properties. The Test Suite Result form opens. General information regarding the test suite results is provided.

31 

To view individual test results, select an entry in the Results tab and click Properties. The Test Result form opens. Review the test results.

32 

To view the details of the test suite created for the test, click Test Suite View at the lower left-hand corner of the form. The OAM Contextual Test form closes and the Test Suite (Edit) form opens.

You can also view the SAPs or sites you selected for the test in the Contextual Tested Entity tab of the Test Suite (Edit) form.
