destination-port (Trace test instance)

Function

The destination-port command can configure the destination port number of an NQA trace test instance.

The undo destination-port command can restore the default setting.

By default, the destination port number of a trace test is 33434.

Usage Guidelines

Usage Scenario

NQA monitors service features by creating test instances. In NQA, two test ends are called an NQA client and an NQA server. An NQA test is initiated by the NQA client. After test instances are configured on the client, NQA places different types of test instances into various test queues. After the test starts, a response packet is returned. Carriers can then check the operating status about protocols by analyzing the received response packet.

For a test instance, the port for accessing the server is specified using the destination port number configured using the destination-port command on the client.

Precautions

If parameters need to be changed during the running of the test instance, the system prompts you whether to terminate the test instance. Press "Y" or "N" as required.

If you press "Y", the test instance is terminated and parameters changed. The settings take effect after being committed. To restart the test instance, run the start command.
If you press "N", the test instance keeps running, and the parameters fail to be modified.
Ports 33434 to 33678 are the default ports for tracert. If these ports are used as the destination ports for NQA test instances, NQA packets may be discarded due to rate limiting. You are advised to use ports other than ports 33434 to 33678 as the destination ports of NQA test instances.

Example

# Set the destination port number for the test instance named user test.
