Parameters

inbound: Performs CAR for incoming packets on the interface.

outbound: Performs CAR for outgoing packets on the interface.

any: Performs CAR for all the IP data packets in the specified direction.

acl [ ipv6 ] acl-number: Performs CAR for packets matching an ACL specified by its number. If ipv6 is not

specified, this option specifies an IPv4 ACL. If ipv6 is specified, this option specifies an IPv6 ACL.

carl carl-index: Performs CAR for packets matching a CAR list specified by its number in the range of 1

to 199.

cir committed-information-rate: Specifies CIR in kbps.

cbs committed-burst-size: CBS in bytes, which specifies the size of bursty traffic when the actual average

rate is not greater than CIR.

ebs excess-burst-size: Specifies the EBS in bytes. The default and the value range for this argument

depend on the device model.

pir peak-information-rate: Specifies the PIR in kbps. When the PIR is not configured, one token bucket is

used. When the PIR is configured, two token buckets are used.

green: Action to take on packets when the traffic rate conforms to CIR. The default is pass.

red: Action to take on packets when the traffic rate conforms to neither CIR nor PIR. The default is discard.

yellow: Action to take on packets when the traffic rate exceeds CIR but conforms to PIR. The default is

pass.

action: Action to take on packets:

• continue: Continues to process the packet using the next CAR policy.

• discard: Drops the packet.

• pass: Permits the packet to pass through.

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

and continues to process the packet using the next CAR policy. The new-cos argument ranges from

0 to 7.

• 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 ranges from 0 to 7.
