Usage Guidelines

Usage Scenario

To set the reply mode for an NQA LSP test instance, run the lsp-replymode command.

By default, a UDP packet is used to respond to an NQA test request. If no-reply is configured, the destination will send no packet for response. In most cases, no-reply is configured when NQA test packets received on the destination are used only for statistics collection or other applications.

Configuration Impact

If no-reply is configured, the NQA test instance will fail because it receives no reply packet.

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

# Configure the test instance named user test to respond to test requests with UDP packets.
