The question

We have a server port that keeps flapping status in UCS Manager. I have swapped the cable and the SFP, but it still happens. Is this an issue with the Fabric Interconnect port itself, or could it be a driver-level issue on the blade? Looking for advice on how to troubleshoot physical port instability.
