Usage Guidelines

Usage Scenario

NQA provides NQA test instances to test network operation conditions, to export statistics, and to effectively cut costs. NQA measures the performance of different protocols running on the network.

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.

No history record about the failed UDP Jitter test instances exist.

Precautions

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

When NQA test result table and historical table are displayed in a split screen, latest results are displayed to improve user experience.
