Usage Guidelines

Usage Scenario

To reduce high bandwidth consumption caused by proactive measurement, run the test start-regular command to start periodic proactive measurement and calculate the two-way packet loss rate, delay, and jitter based on the sequence number and timestamp information in the packets.

Prerequisites

A TWAMP Light session has been created using the test-session command.

Precautions

When a TWAMP Light session is deleted, its periodic proactive measurement is also deleted.
After a Session-Sender is deleted, all periodic proactive measurement configurations will be deleted.
If a TWAMP Light session works in proactive measurement mode, no periodic proactive measurement can be started for it.
If a TWAMP Light session works in on-demand measurement mode and periodic proactive measurement is started, on-demand measurement stops immediately, and the system starts periodic proactive measurement.
The command may be successfully executed but fail to be implemented due to insufficient board resources. If so, the State field of the TWAMP Light session is displayed as inactive in the display twamp-light test-session command output.
