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. You can then check the operating status about protocols by analyzing the received response packet.
For a test instance, the server is specified using the destination IP address configured using the
destination-address command.
For example, to monitor whether the peer device is reachable, run the
nqa command to create an NQA test instance, set the test type to ICMP, and then run the
destination-address command to configure the IP address of the peer device as the destination IP address. After that, you can start the test instance. Based on the response packet, you can check whether the peer device is reachable.
Configuration Impact
If a destination IP address has been configured for a test instance, running the destination-address command overrides the previous configuration.
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.
