EXAMPLE
This example creates a policy called “rd-policy,” uses the class command to
specify the previously defined “rd-class,” uses the set phb 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 cos This command modifies the class of service (CoS) value for a matching

COMMAND USAGE
◆ The set cos command is used to set the CoS value in the VLAN tag for
matching packets.
◆ The set cos and set phb command function at the same level of
priority. Therefore setting either of these commands will overwrite any
action already configured by the other command.
