Chapter 4 Configuring Interfaces
Configuring Optional Interface Features
To define an interface-range macro, perform this task:
This example shows how to define an interface-range macro named enet_list to select Fast Ethernet
interfaces 5/1 through 5/4:
Switch(config)# define interface-range enet_list fastethernet 5/1 - 4
To show the defined interface-range macro configuration, perform this task:
This example shows how to display the defined interface-range macro named enet_list:
Switch# show running-config | include define
define interface-range enet_list FastEthernet5/1 - 4
Switch#
To use an interface-range macro in the interface range command, perform this task:
This example shows how to change to the interface-range configuration mode using the interface-range
macro enet_list:
Switch(config)# interface range macro enet_list
Switch(config-if)#
