Configuring ACL Classification

You can classify traffic by matching packets based on an existing access control list (ACL). Traffic is classified
by the criteria defined in the ACL. The permit and deny ACL keywords are ignored in the matching; even
though a match criteria in the access-list has a deny action, it is still used for matching for this class.
Note Use the class-map class_acl command to display the ACL class-map configuration.
SUMMARY STEPS
1. configure terminal
2. class-map [type qos] [match-any | match-all] class-name
3. match access-group name acl-name
