We are having issues here in our data center.
Background : We have migrated all of the Catalyst switches with Nexus and FEX.
Now we have all of the CIMC ports on UCS standalone servers ( UCS 220 and UCS 240 M3 and M4s connecting to the NEXUS FEX ( 2248 ) in different RACKS.
Problem Description: The CIMC ports keep on dropping at some random intervals.
When I login to the Nexus, I find that ports are up and connected.
The only issue I find is it does not get any input packets from the server.
The only way to recover it is to bounce the port (shut/no shut).
It stays on for some time and then again runs into the same problem.
Already tried: We already tried to change the speed/duplex settings on the switch.
Servers CIMC are running in dedicated mode with static IP from CIMC.
I would appreciate if someone shares their experience if they ran into the same issue and have any recovery steps available.
Thank you.
