• 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 value range for new-cos is 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 value range for new-cos is 0 to 7.
• remark-dscp-continue new-dscp: Remarks the packet with a new DSCP value and hands it over to
the next CAR policy. The value range for new-dscp is 0 to 63. Alternatively, you can specify the
new-dscp argument with af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cs1,
cs2, cs3, cs4, cs5, cs6, cs7, default, or ef.
• remark-dscp-pass new-dscp: Remarks the packet with a new DSCP value and permits the packet to
pass through. The value range for new-dscp is 0 to 63. Alternatively, you can specify the new-dscp
argument with af11, af12, af13, af21, af22, af23, af31, af3
2, af33, af41, af42, af43, cs1, cs2, cs3,
cs4, cs5, cs6, cs7, default, or ef.
• remark-mpls-exp-continue new-exp: Sets the EXP field value of the MPLS packet to new-exp and
continues to process the packet using the next CAR policy. The new-exp argument ranges from 0 to
7.
• 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-continue new-precedence: Remarks the packet with a new IP precedence and hands
it over to the next CAR policy. The value range is 0 to 7.
• remark-prec-pass new-precedence: Remarks the packet with a new IP precedence and permits the
packet to pass through. The value range is 0 to 7.
Usage guidelines
You can configure multiple CAR policies on an interface. The CAR policies are applied in the order they
are configured.
Examples
# Perform CAR for all packets in the outbound direction of GigabitEthernet 2/1/0. The CAR parameters
are as follows: CIR is 200 kbps, CBS is 50000 bytes and EBS is 0; conforming packets are transmitted,
and excess packets are set with an IP precedence of 0 and transmitted.
