Usage Guidelines
Usage Scenario
The lsp-exp command sets the LSP EXP value in MPLS Echo Request packets of an NQA test instance.
Test packets are added to different queues based on their LSP EXP values, which provides the following advantages:
Congestion on the link can be prevented
The specified queue can be monitored.
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.
Example
# Set the LSP EXP value in test packets of the test instance named user test to 5.
