To disable the switch from sending MAC address notification traps, use the no snmp-server enable 
traps mac-notification global configuration command. To disable the MAC address notification traps 
on a specific interface, use the no snmp trap mac-notification {added | removed} interface 
configuration command. To disable the MAC address notification feature, use the no mac address-table 
notification global configuration command.

This example shows how to specify 172.20.10.10 as the NMS, enable the switch to send MAC address 
notification traps to the NMS, enable the MAC address notification feature, set the interval time to 
60 seconds, set the history-size to 100 entries, and enable traps whenever a MAC address is added on 
the specified port.

Switch(config)# snmp-server host 172.20.10.10 traps private

Switch(config)# snmp-server enable traps mac-notification

Switch(config)# mac address-table notification

Switch(config)# mac address-table notification interval 60

Switch(config)# mac address-table notification history-size 100

Switch(config)# interface gigabitethernet0/2

Switch(config-if)# snmp trap mac-notification added

You can verify the previous commands by entering the show mac address-table notification interface 
and the show mac address-table notification privileged EXEC commands.

mac address-table notification [interval value] | 
[history-size value]

Enter the trap interval time and the history table size.

(Optional) For interval value, specify the 
notification trap interval in seconds between 
each set of traps that are generated to the NMS. 
The range is 0 to 2147483647 seconds; the 
default is 1 second.

(Optional) For history-size value, specify the 
maximum number of entries in the MAC 
notification history table. The range is 0 to 500; 
the default is 1.

interface interface-id

Enter interface configuration mode, and specify the 
Layer 2 interface on which to enable the SNMP 
MAC address notification trap.

snmp trap mac-notification {added | removed}

Enable the MAC address notification trap.

Enable the MAC notification trap whenever a 
MAC address is added on this interface.

Enable the MAC notification trap whenever a 
MAC address is removed from this interface.

Return to privileged EXEC mode.

Verify your entries.

(Optional) Save your entries in the configuration 
file.
