Select the required test entity using the appropriate item under the NFM-P Manage menu item, and then click Properties. The entity’s property form opens.

Entities that you can test using this function include:

• VLL, VPLS, and VPRN services (Manage→Service→Services)

• Composite services (Manage→Service→Composite Services)

• Dynamic LSPs (Manage→MPLS→Dynamic LSPs)

• Service tunnels (Manage→Service Tunnels)

Click One Time Validation.

Note: If a regular OAM validation is currently running on the selected test entity, the One Time Validation function will not be executed.

The Choose Validator Test Policy form is displayed and lists all test policies that are applicable to the selected test entity.

Select the required policy from the list and click OK.

Note: A default read-only test policy (Validation-Default-Policy) is supplied for this purpose. You can copy this policy but not modify it. Modify the cloned copy as required, or you can select a test policy you have previously created. See To configure an STM test policy to create an STM test policy.

The One Time Validation function proceeds after you click OK.

The automated operations that occur are as follows:

1. The One Time Validation test suite is created.

2. The selected test entity is added to the test suite.

3. Any tests, MEGs, and MEPs that are appropriate to the test entity and that are required to run the validation are created.

4. The generated tests are executed.

5. The test entity’s OAM Validation Failed state indicator is updated as required (a checkmark indicates the OAM validation failed whereas a blank checkbox indicates that the validation succeeded).

6. Test results for each individual test that was created and executed to perform the validation are copied to new test result objects.

7. The test suite, tests, and any required OAM objects that were created to run the validation are deleted.

To view the test results, click on the tested entity’s Test tab and then on the One Time Validation Result sub-tab.

Note: These archived test results are also available through the STM. They can be viewed by selecting the One Time Validation Result (Assurance) item from the object drop-down menu. See To view and compare STM test suite results for a tested entity for more information.

Select one of the test results in the list and click Properties. The One Time Validation Result (Edit) form opens.

Review the results as required and then close the One Time Validation Result (Edit) form.

Note: The archived test results are not deleted after viewing. They will remain available until manually deleted by the user.

Close the form.
