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.

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.
