Hi, I have problem with IE2000 and IE4000 (i have 6 of them with problems).
In every 10 min i recive message:
Cisco-SFF8472: Floating-point subsystem (SFF8472) Notification Event
%SFF8472-5-THRESHOLD_VIOLATION: Gi1/1: Rx power low alarm; Operating value: -29.6 dBm,
I changed SFP modules (checked 3 different models and brands) with no success. Fiber has been checked and everything is ok. If this message is real i should recive network problems such as STP topology change or connectivity loss. But there is no problem with communication, just that messages.
