Configuring A Range Of Interfaces - Cisco Catalyst 2950 Software Configuration Manual

Using the Interface Command

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:

10-6
Valid entries for port-range:
vlan vlan-ID - vlan-ID, where VLAN ID is from 1 to 1005 with the SI installed or 1 to 4094
–
with the EI installed
fastethernet slot/{first port} - {last port}, where slot is 0
–
gigabitethernet slot/{first port} - {last port}, where slot is 0
–
longreachethernet slot/{first port} - {last port}, where slot is 0
–
– port-channel port-channel-number - port-channel-number, where port-channel-number is
from 1 to 6
You must add a space between the interface numbers and the hyphen when using the
interface range command. For example, the command interface range fastethernet0/1 - 5 is a
valid range; the command interface range fastethernet0/1-5 is not a valid range.
The interface range command works only with VLAN interfaces that have been configured with
the interface vlan command (the show running-config privileged EXEC command output shows
the configured VLAN interfaces). VLAN interfaces that do not appear by using 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
Each comma-separated port-range must consist of the same port
•
type. You do not need to enter spaces before or after the comma.
When you define a range, the space between the first port and the
•
hyphen is required.
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.
