Command History
Usage Guidelines You can enable the MAC change notification feature using the mac-address-table notification change
command. If you do this, you must also enable MAC notification traps on an interface using the
snmp trap mac-notification change interface configuration command and configure the switch to send
MAC change traps to the NMS using the snmp-server enable traps mac-notification global
configuration command.
When the history-size option is configured, the existing MAC change history table is deleted, and a new
table is created.
Examples This example shows how to set the MAC address notification history table size to 300 entries:
Switch(config)# mac-address-table notification change history-size 300
Switch(config)#
This example shows how to set the MAC address notification interval time to 1250 seconds:
Switch(config)# mac-address-table notification change interval 1250
