Configuring A Range Of Interfaces - Cisco Catalyst 3550 series Software Configuration Manual

Using the Interface Command
Note
Step 3 Follow each interface command with the interface configuration commands your particular interface
requires. The commands you enter define the protocols and applications that will run on the interface.
The commands are collected and applied to the interface when you enter another interface command or
enter end to return to privileged EXEC mode.
You can also configure a range of interfaces by using the interface range or interface range macro
global configuration commands. Interfaces configured in a range must be the same type and must be
configured with the same feature options.
Step 4 After you configure an interface, verify its status by using the show privileged EXEC commands listed
in the
Enter the show interfaces privileged EXEC command to see a list of all interfaces on or configured for
the switch. A report is provided for each interface that the device supports or for the specified interface:

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

You do not need to add a space between the interface type and interface number. For example,
in the preceding line, you can specify either gigabitethernet 0/1, gigabitethernet0/1, gi 0/1, or
gi0/1.

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.
