service policies on the specified interface
Chapter 36: Quality of Service Commands
The commands described in this section are used to configure Differentiated
Services (DiffServ) classification criteria and service policies. You can classify traffic
based on access lists, IP Precedence or DSCP values, or VLANs. Using access lists
allows you select traffic based on Layer 2, Layer 3, or Layer 4 information contained
in each packet.

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 specific type of traffic based on an access
list, a DSCP or IP Precedence value, or 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 multiple class statements.
5. 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
