Configuring a Class Map
39
Command Usage
To create a service policy for a specific category or ingress traffic, follow these steps:
1. Use the Configure Class (Add) page to designate a class name for a specific category of traffic.
2. Use the Configure Class (Add Rule) page to edit the rules for each class which specify a type of
traffic based on an access list, a DSCP or IP Precedence value, a VLAN, a CoS value, or a
source port.
3. Use the Configure Policy (Add) page to designate a policy name for a specific manner in which
ingress traffic will be handled.
4. Use the Configure Policy (Add Rule) page to add one or more classes to the policy map. Assign
policy rules to each class by “setting” the QoS value (CoS or PHB) to be assigned to the
matching traffic class. The policy rule can also be configured to monitor the maximum
throughput and burst rate. Then specify the action to take for conforming traffic, or the action
to take for a policy violation.
5. Use the Configure Interface page 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. Use the Traffic > DiffServ (Configure
Class) page to configure a class map.
