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 27-4)to create a service policy (page 27-7)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.
