CoS value. Note that a class map can include match settings for both IP values
and a VLAN.
3.
Use the policy-map command to designate a policy name for a specific manner
in which ingress traffic will be handled, and enter the Policy Map configuration
mode.
4.
Use the class command to identify the class map, and enter Policy Map Class
configuration mode. A policy map can contain up to 16 class maps.
5.
Use the set cos command to modify the per-hop behavior, the class of service
value in the VLAN tag for the matching traffic class, and use one of the police
commands to monitor parameters such as the average flow and burst rate, and
drop any traffic that exceeds the specified rate, or just reduce the DSCP service
level for traffic exceeding the specified rate.
6.
Use the service-policy command to assign a policy map to a specific interface.
Note: Create a Class Map before creating a Policy Map.

Command Usage
◆
First enter this command to designate a class map and enter the Class
Map configuration mode. Then use
match commands to specify the
criteria for ingress traffic that will be classified under this class map.
◆
One or more class maps can be assigned to a policy map ( page 487 ). The
policy map is then bound by a service policy to an interface ( page 491 ). A
service policy defines packet classification, service tagging, and bandwidth
policing. Once a policy map has been bound to an interface, no additional
class maps may be added to the policy map, nor any changes made to the
assigned class maps with the
match or set commands.
