Parameters
cir committed-information-rate: Specifies the committed information rate (CIR) in kbps, which is an
average traffic rate. The value range for committed-information-rate is 8 to 160000000, in increments
of 8.
cbs committed-burst-size: Specifies the committed burst size (CBS) in bytes. The value range for
committed-burst-size is 512 to 256000000, in increments of 512. 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 that is greater than the
product. A default value greater than 256000000 is converted to 256000000.
ebs excess-burst-size: Specifies the excess burst size (EBS) in bytes. The default value for
excess-burst-size is 512. The value range for excess-burst-size is 0 to 256000000, in increments of
512.
pir peak-information-rate: Specifies the peak information rate (PIR) in kbps. The value range for
peak-information-rate is 8 to 160000000, in increments of 8.
green action: Specifies the action to take on packets that conform to the CIR. The default setting is
pass.
red action: Specifies the action to take on packets that conform to neither CIR nor PIR. The default
setting is discard.
yellow action: Specifies the action to take on packets that conform to the PIR but not to the 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
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.
