To handle mac address security, most cataylst series switches have a max mac count command that only allow X number of mac address per port. Set the command to one. The switch will only forward the one address. All others will be drop or forwarded to other ports.

Wouldn't it show the same MAC address for any device on that port? Is there a way to scan or monitor for this activity?
