Configuring A Range Of Interfaces - Cisco Catalyst 3750-X Software Configuration Manual

Chapter 13 Configuring Interface Characteristics
Follow each interface command with the interface configuration commands that the interface requires.
Step 3
The commands that 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.
After you configure an interface, verify its status by using the show privileged EXEC commands listed
Step 4
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
interface range {port-range | macro
Step 2
macro_name}
Step 3
Step 4 end
show interfaces [interface-id]
Step 5
Step 6
copy running-config startup-config
When using the interface range global configuration command, note these guidelines:
•
OL-21521-01
"Monitoring and Maintaining the Interfaces" section on page
Valid entries for port-range:
vlan vlan-ID - vlan-ID, where the VLAN ID is 1 to 4094
–
Purpose
Enter global configuration mode.
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
•
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.
Use the normal configuration commands to apply the configuration
parameters to all interfaces in the range. Each command is executed
as it is entered.
Return to privileged EXEC mode.
Verify the configuration of the interfaces in the range.
(Optional) Save your entries in the configuration file.
