Parameters

cir committed-information-rate: Specifies the committed information rate (CIR) in kbps, which specifies an

average traffic rate. The value range for the committed-information-rate argument is an integral multiple

of 8 between 8 and 160000000.

cbs committed-burst-size: Specifies the committed burst size (CBS) in bytes. The value range for the

committed-burst-size argument is an integral multiple of 512 between 512 and 256000000. The default

value for this argument is the product of 62.5 and the CIR and must be an integral multiple of 512. When

the product is not an integral multiple of 512, it is rounded up to the nearest integral multiple of 512. A

default value greater than 256000000 is converted to 256000000.

ebs excess-burst-size: Specifies the excess burst size (EBS) in bytes. The value range for the

excess-burst-size argument is an integral multiple of 512 between 0 and 256000000, and the default

value is 512.

pir peak-information-rate: Specifies the peak information rate (PIR) in kbps. The value range for the

peak-information-rate argument is an integral multiple of 8 between 8 and 160000000. If the PIR is

configured, two rates are used for traffic policing. Otherwise, one rate is used.

green action: Specifies the action to take on packets that conform to CIR. The default setting is pass.

red action: Specifies the action to take on the packet that conforms to neither CIR nor PIR. The default

setting is discard.

yellow action: Action to take on packets that conform to PIR but not to CIR. The default setting is pass.

action: Sets the action to take on the packet:

• discard: Drops the packet.

• pass: Permits the packet to pass through.

• remark-dot1p-pass new-cos: Sets the 802.1p priority value of the 802.1p packet to new-cos and

permits the packet to pass through. The new-cos argument is in the range of 0 to 7.

• remark-dscp-pass new-dscp: Sets the DSCP value of the packet to new-dscp and permits the packet

to pass through. The new-dscp argument is in the range of 0 to 63.

• remark-lp-pass new-local-precedence: Sets the local precedence value of the packet to

new-local-precedence and permits the packet to pass through. The new-local-precedence argument

is in the range of 0 to 7.

Usage guidelines

A QoS policy that references the traffic behavior can be applied in either the inbound direction or

outbound direction of an interface.

If you configure 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 as follows:

• 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.
