Example
This example creates a policy called "rd-policy, " uses the
the previously defined "rd-class, " uses the set command to classify the service that
incoming packets will receive, and then uses the
average bandwidth to 100,000 Kbps, the burst rate to 4000 bytes, and configure the
response to drop any violating packets.
Console(config)#policy-map rd-policy
Console(config-pmap)#class rd-class
Console(config-pmap-c)#set ip dscp 3
Console(config-pmap-c)#police flow 10000 4000 conform-action transmit
violate-action drop
Console(config-pmap-c)#
This command defines a traffic classification upon which a policy can act, and
enters Policy Map Class configuration mode. Use the no form to delete a class map.

Command Usage
◆
Use the policy-map
configuration mode. Then use the class command to enter Policy Map Class
configuration mode. And finally, use the set command and one of the police
commands to specify the match criteria, where the:
set phb command sets the per-hop behavior value in matching packets.
■
(This modifies packet priority for internal processing only.)
■ set cos command sets the class of service value in matching packets.
(This modifies packet priority in the VLAN tag.)
set ip dscp command sets the IP DSCP value in matching packets.
■
(This modifies packet priority in the IP header.)
police commands define parameters such as the maximum throughput,
■
burst rate, and response to non-conforming traffic.
