default setting is pass.
action: Sets the action to take on the packet:
•
discard: Drops the packet.

Usage guidelines
To use two rates for traffic policing, configure the car command with the pir peak-information-rate
option. To use one rate for traffic policing, configure the car command without the pir
peak-information-rate option.
A QoS policy that uses a traffic behavior configured with CAR can be applied in either the inbound
direction or outbound direction of an interface.
If you execute the car command multiple times in the same traffic behavior, the most recent
configuration takes effect.
Examples
# Configure a CAR action in traffic behavior database:
•
Set the CIR to 200 kbps, CBS to 51200 bytes, and EBS to 0.
•
Transmit the conforming packets, and mark the excess packets with DSCP value 0 and transmit
them.
