Hello all,
We've recently developed a logging message on our 4510.
Threshold_violation: T7/2: Rx Power Low alarm; Operating Value: -40.0 dBm, Threshold Value: -31.5 dBm
We have plenty of fiber tools to check this that are calibrated. We are even the owners of that fiber link and can check it for flaws and light loss. We are receiving ample db on that link and the links around it but that particular port is throwing off the alarm.
We have tried reseating the sfp, cleaning the fiber, and shutting the port. Still getting the alarm.
The link is working perfectly fine and even says it is up.
Any idea on this?
Thanks for your help.
