4000 Router Series ACL and QoS Command Reference

• remark-mpls-exp-pass new-exp: Sets the EXP field value of the MPLS packet to new-exp and permits

the packet to pass through. The new-exp argument ranges from 0 to 7.

• remark-prec-pass new-precedence: Sets the IP precedence of the packet to new-precedence and

permits the packet to pass through. The new-precedence argument ranges from 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:

• Set the CIR to 200 kbps, CBS to 50000 bytes, and EBS to 0.

• Transmit the conforming packets, and mark the excess packets with DSCP value 0 and transmit

them.
