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 14-4) to create a service policy
(page 14-7) 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.
