I have a bunch of 3500XL switches thruout my customer's lan. They are having a problem with unknown mac keep appearing and disappearing from the network.
I can trace the mac-address of the unknown station by "show mac" from the swtich CLI. What's strange is that it appears at one switch, but a minute later it appears in the different switch. what's even more strange is that all NT/2000 servers log shows there is an IP conflict with this mac address. Of course, the servers IP function stops due to this duplicate IP, but comes back in a few minutes. All the servers report the duplicate IP comes from the same mac address. Has anyone seen this problem?
