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 only
specify one item to match when assigning ingress traffic to a class map.
• The class map uses the Access Control List filtering engine, so you must also set
an ACL mask to enable filtering for the criteria specified in the Class Map. See
“Configuring an IP ACL Mask” on page 8-10 or “Configuring a MAC ACL Mask” on
page 8-12 for information on configuring an appropriate ACL mask.
• The class map is used with a policy map (page 14-5) to create a service policy
(page 14-8) 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.
