Configuration example
Configure an aggregation CAR to rate-limit the traffic of VLAN 10 and VLAN 100 received on
GigabitEthernet 2/0/1 using these parameters: CIR is 256 kbps, CBS is 2000 bytes, and the action for
red packets is discard.
# Configure an aggregation CAR according to the rate limit requirements.

# Create class 1 to match traffic of VLAN 10; create behavior 1, and reference the aggregation CAR in
the behavior.
