start (NQA view)

Function

The start command sets the start mode and end mode for an NQA test instance.

The undo start command stops the running NQA test instance. If the start at or start delay command is run but does not take effect, running the undo start command will delete the previous configuration. The undo start command functions the same as the stop command.

By default, the test stops automatically after test packets are sent.

Usage Guidelines

Usage Scenario

To set the start and end mode for an NQA test instance, run the start command.

The start command applies to the following scenarios:

Starting or stopping a test instance at a specific time: Run the start at yyyy/mm/dd hh:mm:ss end at yyyy/mm/dd hh:mm:ss command.
Starting a test instance at a specific time and stopping the test instance after a specified delay: Run the start at yyyy/mm/dd hh:mm:ss lifetime seconds second command.
Starting a test instance after a specified delay and stopping the test instance at a specific time: Run the start delay seconds second end at yyyy/mm/dd hh:mm:ss command.
Starting a test instance immediately and stopping the test instance after a specified delay: Run the start now lifetime seconds second command.
Starting or stopping a test instance both at a fixed time every day: Run the start daily hh:mm:ss to hh:mm:ss command.
Use a proper start mode of a test instance as needed.
A generalflow test instance only supports the start now parameter.

Configuration Impact

If the start daily command is run more than once, the latest configuration overrides the previous one.

Precautions

If the number of the running test instances reaches the maximum value defined by the system, the start command is invalid.

For the same test instance, the start now command can be used again only after the previous test is complete.

When two NQA generalflow test instances that bound to the same physical interface but different VLANs are performed together, the test result may be inaccurate.

If a large number of test instances are running in a non-periodic test, wait for a period before starting new test instances.
