Catalyst 3560 Switch Cisco IOS Commands
For the match ip dscp dscp-list or the match ip precedence ip-precedence-list command, you can enter
a mnemonic name for a commonly used value. For example, you can enter the match ip dscp af11
command, which is the same as entering the match ip dscp 10 command. You can enter the match ip
precedence critical command, which is the same as entering the match ip precedence 5 command. For
a list of supported mnemonics, enter the match ip dscp ? or the match ip precedence ? command to
see the command-line help strings.
Use the input-interface interface-id-list keyword when you are configuring an interface-level class map
in a hierarchical policy map. For the interface-id-list, you can specify up to six entries.
Examples
This example shows how to create a class map called class2, which matches all the incoming traffic with
DSCP values of 10, 11, and 12:
Switch(config)# class-map class2
Switch(config-cmap)# match ip dscp 10 11 12
Switch(config-cmap)# exit
This example shows how to create a class map called class3, which matches all the incoming traffic with
IP-precedence values of 5, 6, and 7:
Switch(config)# class-map class3
Switch(config-cmap)# match ip precedence 5 6 7
Switch(config-cmap)# exit
This example shows how to delete the IP-precedence match criteria and to classify traffic using 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 specify a list of physical ports to which an interface-level class map in a
hierarchical policy map applies:
Switch(config)# class-map match-all class4
Switch(config-cmap)# match input-interface gigabitethernet0/1 gigabitethernet0/2
Switch(config-cmap)# exit
This example shows how to specify a range of physical ports to which an interface-level class map in a
hierarchical policy map applies:
Switch(config)# class-map match-all class4
Switch(config-cmap)# match input-interface gigabitethernet0/1 - gigabitethernet0/5
Switch(config-cmap)# exit
You can verify your settings by entering the show class-map privileged EXEC command.
