Parameters cir committed-information-rate: Specifies the committed information rate (CIR) in kbps. The committed-information-rate argument ranges from 8 to 32000000 and must be a multiple of 8. cbs committed-burst-size: Specifies the committed burst size (CBS) in bytes. • If you do not specify the cbs keyword, the CBS is 62.5 × committed-information-rate by default and must be in the range of 512 to 16000000. • If you specify the cbs keyword, the CBS ranges from 512 to 16000000. ebs excess-burst-size: Specifies the excess burst size (EBS) in bytes. The excess-burst-size argument ranges from 0 to 16000000 and defaults to 512. pir peak-information-rate: Specifies the peak information rate (PIR) in kbps. The peak-information-rate argument ranges from 8 to 32000000 and must be a multiple of 8. green action: Specifies the action to take on a packet that conforms to CIR. The default is pass. yellow action: Specifies the action to take on a packet that conforms to PIR but not to CIR. The default is pass. red action: Specifies the action to take on a packet that conforms to neither CIR nor PIR. The default is discard. 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 of the packet to new-cos and permits the packet to pass through. The new-cos argument ranges from 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 ranges from 0 to 63 or is a keyword in Table 17. • remark-lp-pass new-local-precedence-Sets the local precedence of the packet to new-local-precedence and permits the packet to pass through. The new-local-precedence argument ranges from 0 to 7. Description Use car to configure a CAR action in a traffic behavior. Use undo car to delete a CAR action from a traffic behavior. You can use a CAR action to rate limit inbound or outbound traffic. A traffic behavior can have only one CAR action. If you configure the car command multiple times in a traffic behavior, the last configuration takes effect. Related commands: qos policy, traffic behavior, and classifier behavior. Examples # Configure a CAR action in the traffic behavior database: • Set the CIR to 128 kbps, CBS to 50000 bytes, and EBS to 0. • Allow the conforming packets to pass, and mark the excess packets with DSCP precedence 0 and forward them. system-view [Sysname] traffic behavior database [Sysname-behavior-database] car cir 128 cbs 50000 ebs 0 green pass red remark-dscp-pass 0 43

Description
Use
car
to configure a CAR action in a traffic behavior.
Use
undo car
to delete a CAR action from a traffic behavior.
You can use a CAR action to rate limit inbound or outbound traffic.
A traffic behavior can have only one CAR action. If you configure the
car
command multiple times in a
traffic behavior, the last configuration takes effect.
Related commands:
qos policy
,

, and
classifier behavior
.
Examples
# Configure a CAR action in the traffic behavior
database
:
•
Set the CIR to 128 kbps, CBS to 50000 bytes, and EBS to 0.
•
Allow the conforming packets to pass, and mark the excess packets with DSCP precedence 0 and
forward them.
