6.7.3 Triggering an Alarm for Packets with All-0 MAC Addresses
Context
After receiving the first packet with an all-0 source MAC address or destination MAC address,
the AR3200 router discards the packet and sends a trap to the NMS. When receiving packets
with the same MAC address, the router does not send a trap to the NMS and discards the packets
directly. To trigger the alarm on packets with an all-0 MAC address again, perform the following
steps.

Step 2 Run:
drop illegal-mac alarm
