Configuring Quality of Service Parameters

To create a service policy for a specific category or ingress traffic, follow
these steps:
1.Use the "Class Map" to designate a class name for a specific category of
traffic.
2.Edit the rules for each class to specify a type of traffic based on an
access list, a DSCP or IP Precedence value, or a VLAN.
3.Use the "Policy Map" to designate a policy name for a specific manner in
which ingress traffic will be handled.
4.Add one or more classes to the Policy Map. Assign policy rules to each
class by "setting" the QoS value to be assigned to the matching traffic class.
The policy rule can also be configured 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.
5.Use the "Service Policy" to assign a policy map to a specific interface.

Configuring a Class Map

A class map is used for matching packets to a specified class.
Command Usage
• To configure a Class Map, follow these steps:
- Open the Class Map page, and click Add Class.
- When the Class Configuration page opens, fill in the "Class Name"
field, and click Add.
- When the Match Class Settings page opens, specify type of traffic for
this class based on an access list, a DSCP or IP Precedence value, or
a VLAN, and click the Add button next to the field for the selected
traffic criteria. You can specify up to 16 items to match when
assigning ingress traffic to a class map.
• The class map is used with a policy map (page 3-221) to create a service
policy (page 3-225) for a specific interface that defines packet
classification, service tagging, and bandwidth policing. Note that one
or more class maps can be assigned to a policy map.
