◆
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.
E
XAMPLE
This example creates a policy called “rd-policy,” uses the class command to
specify the previously defined “rd-class,” uses the set cos command to
classify the service that incoming packets will receive, and then uses the
police flow command to limit the average bandwidth to 100,000 Kbps, the
burst rate to 4000 bytes, and configure the response to drop any violating
packets.

set phb
This command services IP traffic by setting a per-hop behavior value for a
matching packet (as specified by the match command) in the ToS field of
the IP header. Use the no form to remove this setting.
