Configuring Layer 2 Interfaces - Cisco Catalyst 2950 Software Configuration Manual

Configuring Layer 2 Interfaces

This example shows how to define an interface-range macro named enet_list to select Fast Ethernet ports
1 to 4 and to verify the macro configuration:
Switch# configure terminal
Switch(config)# define interface-range enet_list fastethernet0/1 - 4
Switch(config)# end
Switch# show running-config | include define
define interface-range enet_list FastEthernet0/1 - 4
Switch#
This example shows how to create a multiple-interface macro named macro1:
Switch# configure terminal
Switch(config)# define interface-range macro1 fastethernet0/1 - 2, fastethernet0/5 - 7
Switch(config)# end
Switch#
This example shows how to enter interface range configuration mode for the interface-range macro
enet_list:
Switch# configure terminal
Switch(config)# interface range macro enet_list
Switch(config-if-range)#
This example shows how to delete the interface-range macro enet_list and to verify that it has been
deleted.
Switch# configure terminal
Switch(config)# no define interface-range enet_list
Switch# show run | include define
Switch#
