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 |

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
notification 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 enable 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 enable traps mac-notification change
