Chapter 11 Configuring Interface Characteristics
Configuring Ethernet Interfaces
• The VLAN interfaces must have been configured with the interface vlan command. The show
running-config privileged EXEC command displays the configured VLAN interfaces. VLAN
interfaces not displayed by the show running-config command cannot be used as interface-ranges.
• All interfaces defined as in a range must be the same type (all Gigabit Ethernet ports, all 10-Gigabit
Ethernet ports, all EtherChannel ports, or all VLANs), but you can combine multiple interface types
in a macro.
This example shows how to define an interface-range named enet_list to include ports 1 and 2 on
switch 1 and to verify the macro configuration:
Switch# configure terminal
Switch(config)# define interface-range enet_list gigabitethernet1/0/1 - 2
Switch(config)# end
Switch# show running-config | include define
define interface-range enet_list GigabitEthernet1/0/1 - 2
This example shows how to create a multiple-interface macro named macro1:
Switch# configure terminal
Switch(config)# define interface-range macro1 gigabitethernet1/0/1 - 2,
gigabitethernet1/0/5 - 7, tengigabitethernet1/0/1 -2
Switch(config)# end
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 was deleted.
Switch# configure terminal
Switch(config)# no define interface-range enet_list
Switch(config)# end
Switch# show run | include define
Switch#
