Configure the CAR Policy Based on the MAC Address
The packet input to router A serial interface 0 (the source address of the packet is
00e0.34b0.7676) is matched with the CAR policy based on MAC address. A
packet that meets the conditions after its priority level value is changed to 7 will be
sent continuously and dropped if it does not.
