Usage Guidelines

Usage Scenario

To perform an OTDR test to obtain reflection distances of optical fibers, run the otdr capture interface command. The reflection distances are used for fiber fault diagnosis. To query historical OTDR test results, run the display otdr capture history-record interface command.

Precautions

The command can be run multiple times.
Running the otdr capture interface command will not generate any configuration in a configuration file. Therefore, historical OTDR test results will be cleared after a device restarts.

Example

# Trigger an OTDR test on GE0/0/1.
