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.
[Sysname] interface ten-gigabitethernet 1/0/1 [Sysname-Ten-GigabitEthernet1/0/1] mac-address notification mac-move suppression
