I'm having a Nexus 3064pq in Layer core being a core network. Today I have a problem where a 10Gbps 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:
