I have two nexus 5548's configured as a vPC peers and two ucs 6120's configure in a cluster. The 5548's are connected to two catalyst 6500 via trunks that are in a VSS configuration. My question is, i have the ucs 6120 managment 0 ports connected to the 5k's, 6120-A mgmt0 to 5k-1 and 6120-B to 5k-2, everytime i fail the ucs 6120-A (primary) i lose ping to the cluster ip and can't manage ucs 6120-B at all even though it is pingable. Below are snippets on how the management ports are configured on the 5K's. Any Idea's?
nx5k-1

you need to configure UCS management failover monitoring

nks for the quick reply. I have setup management failover monitoring but when i failover from 6120-A to 6120-B i still lose ping to the cluster ip and all of management.

How do you have it configured? It can take a few minutes or more depending on the configuration

Wait a minute, I just noticed that you have your management interfaces in a port channel and vPC?
Those should be setup as standalone access ports, there isn't a UCS side configuration to place those into a port channel. They are on different Fabric Interconnects anyway.
