I'm curious if anyone who has enabled port-security has experienced this issue. I've enabled port-security on some distribution switches. Two of those switches are connected for redundancy. On a few occassions, I have seen port-security errors crop up on those switches that don't make sense. For example, I've seen a violation error come up on both of those switches, at the same time, for a device that is actually plugged into an access switch's port. I know for sure that the violating device wasn't plugged into these two distribution ports simultaneously. I also know for sure that the device was never moved off of the access switch. So why would the distribution switches report a violation? Could this be because of some STP change? Bug? Something else?
Any input would be appreciated.
