Parameters
car-name: Specifies the name of the aggregate CAR action. This argument must start with a letter,
and is a case-sensitive string of 1 to 31 characters.
cir committed-information-rate: Specifies the 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 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 EBS in bytes. The value range for excess-burst-size is 0 to
256000000, in increments of 512. The default is 512.
pir peak-information-rate: Specifies the 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 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: Specifies the action to take on packets that conform to PIR but not to CIR. The default
setting is pass.
action: Specifies the action to take on packets:
• 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: Remarks the packet with a new DSCP value and permits the
packet to pass through. The new-dscp argument is in the range of 0 to 63. Alternatively, you can
specify the new-dscp argument with af11, af12, af13, af21, af22, af23, af31, af32, af33, af41,
af42, af
43, cs1, cs2, cs3, cs4, cs5, cs6, cs7, default, or ef.
Usage guidelines
To use two rates for aggregate CAR, configure the qos car command with the pir
peak-information-rate option. To use one rate for aggregate CAR, configure the qos car command
without the pir peak-information-rate option.
