Interface Range Command on CISCO Router/Switch

Command

Interface Range

Use

This is the modern way to configure VLANs. A useful feature is that you can configure a range of VLANs with a single command.

Syntax

Switch(config)#interface range <range>

Options

< – > Allows for a continuous range to be specified such as interface range fa0/1-24
< ,> Allows for a specific interface to be selected such as interface range fa0/3 , fa0/10

Example

In the below example we will disable ports Fa0/1-24 on SW1.

SW1(config)#interface range fa0/1-24
SW1(config-if-range)#shut
SW1(config-if-range)#
