Usage Guidelines

To view historical OTDR test results on a specified interface, run the display otdr capture history-record interface command. Each test result displays reflection distances of 16 fibres, and the command output can display the latest 10 OTDR test results at most. If the reflection distance of an optical fiber is 0, the optical module connected to the optical fiber does not support OTDR testing.

Example

# Display historical OTDR test results on GE0/0/1.
