Chapter 2 Catalyst 3750 Switch Cisco IOS Commands
class-map
To define packet classification on a physical-port basis, only one match command per class map is
supported. In this situation, the match-all and match-any keywords are equivalent.
Only one access control list (ACL) can be configured in a class map. The ACL can have multiple access
control entries (ACEs).
Examples This example shows how to configure the class map called class1 with one match criterion, which is an
access list called 103:
Switch(config)# access-list 103 permit ip any any dscp 10
Switch(config)# class-map class1
Switch(config-cmap)# match access-group 103
Switch(config-cmap)# exit
This example shows how to delete the class map class1:
Switch(config)# no class-map class1
You can verify your settings by entering the show class-map privileged EXEC command.
