Managing the MAC Address Table
To disable MAC address-change notification traps, use the no snmp-server enable traps
mac-notification change global configuration command. To disable the MAC address-change
notification traps on a specific interface, use the no snmp trap mac-notification change {added |
removed} interface configuration command. To disable the MAC address-change notification feature,
use the no mac address-table notification change global configuration command.
This example shows how to specify 172.20.10.10 as the NMS, enable the switch to send MAC address
n
otification traps to the NMS, enable the MAC address-change notification feature, set the interval time
to 123 seconds, set the history-size to 100 entries, and e
nable traps whenever a MAC address is added
on the specified port.
Switch(config)# snmp-server host 172.20.10.10 traps private mac-notification
Switch(config)# snmp-server enabl
e traps mac-notification change
Switch(config)# mac address-table

You can verify your settings by entering the show mac address-table notification change interface and
the show mac address-table notification change privileged EXEC commands.
Configuring MAC Address Move Notification Traps
When you configure MAC-move notification, an SNMP notification is generated and sent to the network
management system whenever a MAC address moves from one port to another within the same VLAN.
