Usage guidelines
This feature shuts an interface down when a MAC address has been moved from the interface more
than the specified suppression threshold within a MAC move detection interval. You can use the
shutdown command and then the undo shutdown command to bring up the interface. Also, the
interface can automatically come up after a suppression interval.
When the MAC address move suppression shuts an interface down, the system sends only syslog
messages to the information center module. If the snmp-agent trap enable mac-address
command is also executed, the system also sends SNMP information to the SNMP module of the
device.
