Usage guidelines
This feature shuts an interface down when a MAC address has been moved to or from the interface
more than the suppression threshold within a MAC move detection interval. The shutdown interface
automatically goes up after a suppression interval. Also, you can use the shutdown command and
then the undo shutdown command to bring up the interface.
When 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 notifications to the SNMP module.
Examples
# Enable MAC address move suppression on Ten-GigabitEthernet 1/0/1.
