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

traps when this amount of time has elapsed. The range is 0 to 2147483647
seconds.
