Chapter8 Configuring Interface Characteristics
Using the Interface Command
•You must add a space between the interface numbers and the hyphen when us ing the
interface range command. For example, the command interface range gigabitethernet 0/1 - 5 is
a valid range; the command interface range gigabitethernet 0/1-5 is not a valid range.
•The interface range command works only with VLA N i nte rfac es th at have been c onfig ure d w ith
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 with the interfac e ran ge command.
•All interfaces in a range must be the same type; that is, all Fast Ethernet ports, all Gigabit Ethernet
ports, all EtherChannel ports, or all SVIs.
This example shows how to use the interface range global configuration command to enable Gigabit
Ethernet interfaces 0/1 to 0/5:
Switch# configure terminal
Switch(config)# interface range gigabitethernet0/1 - 5
Switch(config-if-range)# no shutdown
Switch(config-if-range)#

Gigabit Ethernet interfaces in the range 0/1 to 0/3 and both Gigabit Ethernet interfaces 0/7 and 0/8:
Switch# configure terminal
Switch(config)# interface range gigabitethernet0/1 - 3, gigabitethernet0/7 - 8
Switch(config-if-range)# no shutdown
Switch(config-if-range)#

If you enter multiple configuration commands while you are in interface range mode, each command is
executed as it is entered. The commands are not batched together and executed after you exit interface
range mode. If you exit interface range configuration mode while the commands ar e being ex ecut ed,
some commands might not be executed on all interfaces in the range. Wait until the command prompt
reappears before exiting interface range configuration mod e.
