match (class-map configuration)
This example shows how to delete the IP-precedence match criteria and to classify traffic with acl1:
Switch(config)# class-map class2
Switch(config-cmap)# match ip precedence 5 6 7
Switch(config-cmap)# no match ip precedence
Switch(config-cmap)# match access-group acl1
Switch(config-cmap)# exit
This example shows how to configure a class map called dscp_class whose match criterion is to match
IP DSCP 9. A second class map, called vlan_class, matches traffic on VLANs 10, 20 to 30, and 40 to
class map dscp_class:
Switch(config)# class-map match-any dscp_class
Switch(config-cmap)# match ip dscp 9
Switch(config-cmap)# exit
Switch(config)# class-map match-all vlan_class
Switch(config-cmap)# match vlan 10 20-30 40
Switch(config-cmap)# match class-map dscp_class
Switch(config-cmap)# exit
You can verify your settings by entering the show class-map privileged EXEC command.
