Execute TWAMP Light session tests

Purpose

Use this procedure to execute the TWAMP Light tests created in Create a TWAMP Light test session.

This procedure is based on the procedures to execute an OAM test and view results of an OAM test, in the NSP Data Collection and Analysis Guide.

For example, the reference procedures in NSP Release 24.4 are:

Note: The execution of a test auto-generates telemetry subscriptions. Auto-generated subscriptions can be identified in the Data Collection and Analysis Management, Subscriptions view by their names. The subscription name format is TestSuiteEx_OAM-PM-test_type-statistic-type; for example, the subscription for Twamp-light delay streaming statistics would be named TestSuiteEx_OAM-PM-TWAMP-streaming.

Do not edit or delete these subscriptions.

Steps
 
1 

Log in to the NSP.

2 

Open Data Collection and Analysis Management, Tests.

3 

In the Filter column at the left of the view, select Twamp-Light in the Test type field and click RETRIEVE. The list of TWAMP-Light tests is populated.

4 

Choose a test and click png38.png(Table row actions), Execute. The Execute dialogue opens.

5 

Configure the required parameters and click EXECUTE.

  • The Sync mode parameter specifies whether or not execution requests generate notifications in the UI. The Sync-execute option (default) provides a notification if the execution fails.

  • The Result Classifier parameter specifies the name of the result classifier used to determine test success or failure. Result classifiers are configurable using a REST API.

    Check the Perform result classification check box to apply the classifications.

  • The Publish results check box publishes results to Kafka.

  • The Save results to database check box makes results available to the NSP UI. If this box is not checked, the UI does not display results of the test.

6 

To view results of a test, select the test and click png38.png(Table row actions), View Results.

The Test executions page opens, showing the executions and their results.

Note: After a test has executed, there is a brief processing delay before results are available. For tests that have just finished running, Nokia recommends that you wait a minimum of 5 s before viewing results.
