Chapter 12 Configuring Interface Characteristics
Using Interface Configuration Mode
When using the interface range global configuration command, note these guidelines:
• Valid entries for port-range:
– vlan vlan-ID - vlan-ID, where the VLAN ID is 1 to 4094
– gigabitethernet module/{first port} - {last port} (for Catalyst 3560-E switches), where the
module is always 0
– gigabitethernet stack member/module/{first port} - {last port} (for Catalyst 3750-E switches),
where the module is always 0
tengigabitethernet m
odule/{first port} - {last port} (for Catalyst 3560-E switches), where the
module is always 0
– tengigabitethernet stack member/module/{first port} - {last port} (for Catalyst 3750-E
switches), where the module is always 0
– gigabitethernet stack member/module/{first port} - {last port}, where the module is always 0
– tengigabitethernet stack member/module/{first port} - {last port}, where the module is
always 0
– port-channel port-channel-number - port-channel-number, where the port-channel-number
is 1 to 48
Note When you use the interface range command with port channels, the first and last
port-channel number must be active port channels.
• You must add a space between the first interface number and the hyphen when using the
interface range co
mmand. For example, the command interface range gigabitethernet1/0/1 - 4 is
a valid range; the command interface range gigabitethernet1/0/1-4 is not a valid range.
• The interface range command only works with VLAN interfaces that 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 with the interface range command.
• All interfaces defined 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 enter multiple ranges in a
command.
This example shows how to use the inte
rface range global configuration command to set the speed to
100 Mb/s on ports 1 to 4 on switch 1:
Switch# configure terminal
Switch(config)# interface range gigabitethernet1/0/1 - 4
Switch(config-if-range)# speed 100
Step 3
Use the normal configuration commands to apply the configuration
parameters to all interfaces in the range. Each command is executed
as it is entered.
Step 4
end Return to privileged EXEC mode.
Step 5
show interfaces [interface-id] Verify the configuration of the interfaces in the range.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
