IP, LSP, and P2MP LSP path test policies

Auto OAM for path monitors

You can create test policies to associate to an IP, LSP, or P2MP LSP path monitor. The tests that you define in the policy are executed when the path reroutes. An OAM execution policy controls the automatic execution of tests.

For IP path monitor test policies, you can define ICMP ping and ICMP trace tests. For LSP path monitor test policies, you can define LSP ping and LSP trace tests. For P2MP LSP path monitors, you can define P2MP LSP ping and P2MP LSP trace tests.

IP, LSP, and P2MP LSP path monitor tests run only on operational IP, LSP, and P2MP LSP paths. Additionally, LSP path monitor tests run only on active LSP paths.

IP, LSP, and P2MP LSP path monitor tests within a test suite are executed in the following ways:

• Automatically, using the Auto OAM function. The specified tests are performed when an active path reroutes.

• When you capture a path on the IP, LSP, or P2MP LSP path monitor configuration form.

• When you execute the associated test suite.

• When you manually run the test from the IP, LSP, or P2MP LSP path monitor configuration form.

The CPAM automatically creates a test suite when you assign an STM test policy to an IP, LSP, or P2MP LSP path monitor.

Execution policies

Execution policies allow you to define the parameters that control the execution of the OAM tests. You can associate an execution policy to an IP, LSP, or P2MP LSP path monitor. Execution policies are specific to the CPAM feature set, and are only applied to Auto OAM tests for path monitors. See To configure an OAM test execution policy for more information.

Auto OAM state

The results of Auto OAM tests are displayed on the Path Monitor form, under the Auto OAM tab. In addition, the Auto OAM state for each path record is displayed on the Path History tab of the Path Monitor form. The following Auto OAM states may be displayed:

• Not Applicable

  Tests may not be fully configured for the path monitor; for instance, an STM test policy is not selected. Alternatively, the path record is not for an active path, or the associated LSP is administratively down.

• Dropped

  The internal queue associated with test execution is full, and retries are not successful. After a preset number of retries, the test is dropped. The Priority parameter value configured in the execution policy affects this process. See To configure an OAM test execution policy. Alternatively, there may be duplicate path records. OAM tests for a duplicate path record are dropped.
