It is a security violation when one of these situations occurs:
The maximum number of secure MAC addresses have been added to the address table, and a station whose MAC address is not in the address table attempts to access the interface.
An address learned or configured on one secure interface is seen on another secure interface in the same VLAN.
having said that bullet two is why when moving a laptop to new interface prevents that laptop on connecting through the switch on the new interface. You might want to try adjusting the aging time for the secured mac, but even then you have to tell the users to wait certain amount of time before plugging into the new interface, not very scalable. Previous post suggested mac ACL. I would agree it is a better solution.
