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

Perform one of the following:

1. Create an STM policy. Click Create and choose Test Policy. The Test Policy (Create) form opens.

2. Modify an exiting STM policy. Perform the following:

   1. Choose Test Policy (Assurance) from the object menu, then click Search.

   2. Choose a test policy and click Properties. The Test Policy (Edit) form opens.

   Note: If you modify a test policy that is associated with a test suite, you must click Generate to regenerate the tests in the test suite.

   Note: You can apply changes made to an STM test policy to all associated STM test suites by clicking Update Test Suites at the bottom of the Test Policy (Create|Edit) form.

Configure the required parameters.

Some parameters are configurable only during test policy creation, and cannot be modified for existing test policies.

The NE Schedulable and MEF35 parameters are mutually exclusive. The NE Schedulable parameter must be selected for SAA-type STM test policies. The MEF35 parameter must be selected for PM Session-type STM test policies.

The Test Family parameter is available when the MEF35 Mode parameter is selected. Configure the Test Family parameter as follows:

• Choose the Ethernet option to enable configuration of DMM, SLM, and LMM PM Session tests for Entity Types of VLL, VPLS, or Composite services.

• Choose the IP option to enable configuration of a TWAMP Light PM Session test for Entity Types of VPRN Service or Router.

• Choose the MPLS option to enable configuration of an MPLS DM Session Test for Entity Types of LSP or LSP (MPLS-TP). The LSP entity type includes RSVP and RSVP Auto LSPs.

You must select the NE Schedulable parameter if the test you are creating will be used in a test suite that requires an NE-scheduled policy.

The Strategy parameter in the Test Generation panel is available when the Entity Type parameter is set to VLL Service or VPRN Service.

The Types parameter in the Address Types panel is configurable when the Entity Type parameter is set to VPRN Service.

The Accounting Files parameter is configurable when the NE Schedulable parameter is selected.

The Continuously Executed and Test Result Storage parameters are configurable when the Accounting Files parameter is selected.

Click on one of the following:

1. Test Definitions tab. This tab is available when the MEF35 Mode parameter is not selected. Use this tab to add all OAM test definitions to a test policy except for PM Session OAM test types.

2. PM Session Test Definitions tab. This tab is available when the MEF35 Mode parameter is selected. Use this tab to add all PM Session OAM test definitions to a test policy.

Add one or more test definitions to the policy.

1. Click Add and choose an option from the cascading menu, for example, Services→Add Site Ping or PM Session Test→Add CFM SLM Session Test. The selected test definition form opens.

   The available options and test categories vary, depending on the settings specified for the Entity Type, NE Schedulable, or other parameters in Step 3.

2. Configure the required parameters.

   The available parameters depend on the type of test you chose in 1. See the XML API Reference to view information about configurable parameters and their applicability.

3. Click on each of the remaining tabs on the selected test definition creation form, for instance: Test Parameters, Results Configuration, CFM Details, Bin Group Details, Measurement Interval Details, and so on. Configure the required parameters on each tab. The available tabs vary, depending on the type of test you chose in 1.

4. As required, configure threshold-crossing alarms for the test definition by performing Step 4 to Step 9 of To configure threshold-crossing alarms or NM threshold-crossing alarms for an OAM diagnostic test or STM test policy.

   Note: Configuration of threshold-crossing alarms is optional, and can be performed either during test definition creation, or later; see To configure threshold-crossing alarms or NM threshold-crossing alarms for an OAM diagnostic test or STM test policy.

Save your changes and close the form. The Test Policy (Create|Edit) form is displayed, with test definitions listed on the Test Definitions tab.

CAUTION Service Disruption

Do not modify the test policy while a scheduled task for the suite is enabled

The operation of scheduled test suites that use the test policy may be adversely affected if you modify the test policy while a scheduled task for the suite is enabled.

If you are configuring an existing test policy, click Update Test Suites to apply the test policy changes to all associated test suites.

You can click on the Usages tab to view a list of the test suites that use the test policy.

Save your changes and close the forms.
