E XAMPLE
This example creates a policy called “rd-policy,” uses the class command to
specify the previously defined “rd-class,” uses the set command to classify
the service that incoming packets will receive, and then uses the police
trtcm-color-blind command to limit the average bandwidth to 100,000
Kbps, the committed burst rate to 4000 bytes, the peak information rate to
1,000,000 kbps, the peak burst size to 6000, to remark any packets
exceeding the committed burst size, and to drop any packets exceeding
the peak information rate.

set This command modifies the CoS, DSCP or IP Precedence value in a
matching packet (as specified by the match command). Use the no form to
remove this traffic classification.

[no] set {cos new-cos | ip dscp new-dscp |
ip precedence new-ip-precedence}
new-cos - New Class of Service (CoS) value. (Range: 0-7)
new-dscp - New Differentiated Service Code Point (DSCP) value.
(Range: 0-63)
new-ip-precedence - New IP Precedence value. (Range: 0-7)

◆ The set cos command is used to set the CoS value in the VLAN tag for
matching packets.
◆ The set ip dscp and set ip precedence commands are used to set
these priority values in the packet’s ToS field for matching packets.
◆ Each of these commands function at the same level of priority.
Therefore setting any one of these commands will overwrite the action
configured by the last set command.
