destination-port (TCP test instance view)

Function

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

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

By default, the destination port number of a TCP test instance is 7.

Usage Guidelines

Usage Scenario

NQA detects 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 through commands 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 know the operating status about protocols by analyzing the received response packet.

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

For example, if you need to detect whether the TCP service runs normally on the peer device through a TCP test instance, perform the following configurations:

On the server: Configure the TCP server used for NQA tests, including the client IP addresses that are supported and the TCP port number opened to the client.

On the client:

1.Create an NQA test instance and configure its type as TCP.

2.Configure the IP address of the server as the destination IP address and configure the opened TCP port number on the server as the destination port number.

3.Start the test instance.

Precautions

For TCP test instances, the configured destination port number must be the same as the opened port number on the server.

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.

Example

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