Usage Guidelines The MAC address notification feature sends Simple Network Management Protocol (SNMP) traps to the
network management system (NMS) whenever a new MAC address is added or an old address is deleted
from the forwarding tables. MAC notifications are generated only for dynamic and secure MAC
addresses. Events are not generated for self addresses, multicast addresses, or other static addresses.
When you configure the history-size option, the existing MAC address history table is deleted, and a
new table is created.
You enable the MAC address notification feature by using the mac address-table notification
command. You must also enable MAC address notification traps on an interface by using the snmp trap
mac-notification interface configuration command and configure the switch to send MAC address traps
to the NMS by using the snmp-server enable traps mac-notification global configuration command.
history-size value (Optional) Configure the maximum number of entries in the MAC
notification history table. The range is 0 to 500 entries.
interval value (Optional) Set the notification trap interval. The switch or the switch stack
sends the notification traps when this amount of time has elapsed. The range
is 0 to 2147483647 seconds.
