Hey there,
I have port security turned on my switch stack, with a maximum of two mac addresses, one for voip phone, one for pc.
Intermittently, mac address 7e77.3777.5776 will pop the port. I can't figure out where this mac address is coming from.
Users are reporting that they didn't plug anything else into their ports. I googled that mac and nothing comes up.
Any advice on how to track this down?
Thank you.
