Problem Description
The optical module on the port generates an alarm.
Process Analysis
1. View the diagnostic information display logbuffer and find that the interface has multiple alarms and has been fluctuating.
2. Check the diagnostic information, which shows that the received optical power is low, with a threshold of -3 to -23.01, currently at -22.84. Once it exceeds the threshold, an alarm will be triggered.
Solution
Troubleshoot the link, and if the link is normal, replace the optical module for testing.
