I'm having two Nexus 93108tc in Layer2 switch. two Nexus 93108 connect to 4503 by vPC,Today I have a problem where a 40Gbps(change to 1Gbps) port (1/36) is falling out of nowhere. It gets down and only returns when we remove the gbic cisco and put it back. We already changed the Gbic and the problem continues.
What can it be? Below the log:
