To create a service policy for a specific category of ingress traffic, follow
these steps:
1. Use the class-map command to designate a class name for a specific
category of traffic, and enter the Class Map configuration mode.
2. Use the match command to select a specify type of traffic based on an
access list, a DSCP or IP Precedence value, or a VLAN.
3. Set an ACL mask to enable filtering for the criteria specified in the match
command.
4. 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.
5. Use the class command to identify the class map, and enter Policy Map
Class configuration mode. A policy map can contain multiple class
statements.
6. Use the set command to modify the QoS value for matching traffic class,
and use the policer command to monitor 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.
7. Use the service-policy command to assign a policy map to a specific
interface.
service-policy Applies a policy map defined by the policy-map
command to the input of a particular interface
