Chapter 12 Configuring Interface Characteristics
Using Interface Configuration Mode
Beginning in privileged EXEC mode, follow these steps to configure a range of interfaces with the
same parameters:
When using the interface range global configuration command, note these guidelines:
•
Valid entries for port-range, depending on port types on the switch:
– vlan vlan-ID , where the VLAN ID is 1 to 4094
–
fastethernet stack member/module/{first port } - { last port }, where the module is always 0
–
gigabitethernet 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 6
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 command.
For example, interface range gigabitethernet1/0/1 - 4 is a valid range; interface range
gigabitethernet1/0/1-4 is not.
•
0/1 - 4 0/1-4 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 Fast Ethernet ports, all Gigabit Ethernet
ports, all EtherChannel ports, or all VLANs), but you can enter multiple ranges in a command.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface range { port-range | macro
macro_name }
Specify the range of interfaces (VLANs or physical ports) to be
configured, and enter interface-range configuration mode.
• You can use the interface range command to configure up to five
port ranges or a previously defined macro.
•
The macro variable is explained in the “Configuring and Using
Interface Range Macros” section on page 12-14 .
• In a comma-separated port-range , you must enter the interface
type for each entry and enter spaces before and after the comma.
•
In a hyphen-separated port-range , you do not need to re-enter the
interface type, but you must enter a space before the hyphen.
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.
