Configuring A Range Of Interfaces - Cisco WS-C3560-48PS-S Software Configuration Manual

Using Interface Configuration Mode

Configuring a Range of Interfaces

You can use the interface range global configuration command to configure multiple interfaces with the
same configuration parameters. When you enter the interface range configuration mode, all command
parameters that you enter are attributed to all interfaces within that range until you exit this mode.
Beginning in privileged EXEC mode, follow these steps to configure a range of interfaces with the
same parameters:
Command
Step 1 configure terminal
Step 2
interface range {port-range | macro
macro_name}
Step 3
Step 4 end
Step 5
show interfaces [interface-id]
Step 6 copy running-config startup-config
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 from 1 to 4094
– fastethernet module/{first port} - {last port}, where the module is always 0
gigabitethernet 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
–
from 1 to 12
When you use the interface range command with port channels, the first and last port
Note
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, the command interface range fastgigabitethernet 0/1 - 4
is a valid range; the command interface range fastgigabitethernet 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.
Purpose
Enter global configuration mode.
Enter interface range configuration mode by entering the range of
interfaces (VLANs or physical ports) to be configured.
• 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
Interface Range Macros" section on page
• 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.
You can now use the normal configuration commands to apply the
configuration parameters to all interfaces in the range.
Return to privileged EXEC mode.
Verify the configuration of the interfaces in the range.
(Optional) Save your entries in the configuration file.
