Usage Guidelines

Usage Scenario

NQA test instances can detect network operation conditions, output statistics, and effectively cut costs. NQA measures the performance of different protocols on the network, which allows carriers to collect the operation indicator of networks in real time.

To obtain history records of an NQA test instance, you can run the display nqa history command.

The display nqa history command helps you understand the network status by displaying the operation statistics about each test packet, including the status and round-trip delay.

Configuration Impact

History records of a failed jitter test instance will not be recorded.

Precautions

If no parameter is specified, history records of all NQA test instance are displayed.

Example

The actual command output varies according to the device. The command output here is only an example.
