Usage Guidelines

Usage Scenario

To configure an OTDR test result as the OTDR birth certificate, run the otdr certificate interface command. The OTDR birth certificate is used as a baseline for fault detection. You can run the display otdr certificate interface command to view the OTDR birth certificate. By comparing the fiber reflection distances in OTDR test results (in the display otdr capture history-record interface command output) and the OTDR birth certificate (in the display otdr certificate interface command output), you can determine whether a fault occurs on an optical fiber.

Precautions

This command can be run multiple times, but the latest configuration takes effect.
Running the otdr certificate interface command will not generate any configuration in a configuration file. Therefore, the OTDR birth certificate configuration will be cleared after a device restarts.

Example

# Configure the second OTDR test result as the OTDR birth certificate on GE0/0/1.
