Usage Guidelines
The MAC address notification change 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 change notifications are generated only for dynamic
and secure MAC addresses and are not generated for self addresses, multicast addresses, or other static
addresses.
