Finding Feature Information

Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the Feature Information Table at the end of this document.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/​go/​cfn. An account on Cisco.com is not required.

Prerequisites for the Interface Range Specification

VLAN switch virtual interfaces (SVIs) are required for the interface range specification.

Restrictions for the Interface Range Specification

While you are in interface range configuration mode, each command that you enter is executed as it is entered. The commands are not batched for execution after you exit interface range configuration mode. If you exit interface range configuration mode while the commands are being executed, some commands might not be executed on some interfaces in the range. Wait until the command prompt reappears before exiting interface range configuration mode.

The interface range command works only with VLAN interfaces that have been created with the interface vlan command (the show running-config command displays the VLAN interfaces). VLAN interfaces not displayed by the show running-config command cannot be used with the interface range command.

Information About the Interface Range Specification

• Overview of the Interface Range Specification
• Benefits of the Interface Range Specification

Overview of the Interface Range Specification

The Interface Range Specification feature allows specification of a range of interfaces to which subsequent commands are applied, and it supports the definition of macros that contain an interface range. The Interface Range Specification feature is implemented with the interface range command, which causes the device to enter interface range configuration mode. In this mode, all entered commands are applied to all interfaces within the range at the time the commands are entered.

Benefits of the Interface Range Specification

The Interface Range Specification feature makes configuration easier because:

• Identical commands can be entered once for a range of interfaces, rather than being entered separately for each interface.
• Interface ranges can be saved as macros.

How to Configure the Interface Range Specification

• Defining an Interface-Range Macro
• Configuring a Range of Interfaces

Defining an Interface-Range Macro

SUMMARY STEPS

1.    enable


2.    configure terminal


3.    define interface-range macro-name interface-range


4.    end

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Device> enable	Enables privileged EXEC mode. Enter your password if prompted.
Step 2	configure terminal Example: Device# configure terminal	Enters global configuration mode.
Step 3	define interface-range macro-name interface-range Example: Device(config)# define interface-range macro1 ethernet 1/2 - 5	Defines the interface-range macro and saves it in NVRAM. interface-range—Type of interface range. See the usage guidelines for this command in the Cisco IOS Interface and Hardware Component Command Reference. In the example, the interface-typeslot/first-interfacelast-interface format to used to enter the interface range.
Step 4	end Example: Device(config)# end	Returns to privileged EXEC mode.

Configuring a Range of Interfaces

SUMMARY STEPS

1.    enable


2.    configure terminal


3.    interface range macro macro-name


4.    interface range vlan vlan-id - vlan-id[, vlan vlan-id - vlan-id...]


5.    interface range {ethernet | fastethernet | gigabitethernet} slot/interface - interface [, {ethernet | fastethernet | gigabitethernet} slot/interface - interface...]


6.    end

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Device> enable	Enables privileged EXEC mode. Enter your password if prompted.
Step 2	configure terminal Example: Device# configure terminal	Enters global configuration mode.
Step 3	interface range macro macro-name Example: Device(config)# interface range macro macro1	Enables an interface-range macro. You can enter one macro or up to five comma-separated ranges.
Step 4	interface range vlan vlan-id - vlan-id[, vlan vlan-id - vlan-id...] Example: Device(config)# interface range vlan 500 - 506	Enables the VLAN IDs. Comma-separated ranges can include both VLANs and physical interfaces.
Step 5	interface range {ethernet | fastethernet | gigabitethernet} slot/interface - interface [, {ethernet | fastethernet | gigabitethernet} slot/interface - interface...] Example: Device(config)# interface range fastethernet 5/1 - 5 , gigabitethernet 1/1 - 2	Selects the range of interfaces to be configured. The space before the dash is required. For example, the command interface range gigabitethernet 1/2 - 5 is valid; the command interface range gigabitethernet 1/2-5 is not valid.
Step 6	end Example: Device(config-if-range)# end	Returns to privileged EXEC mode.

Configuration Examples for the Interface Range Specification

• Example: Range Macro Definition
• Example: Single Range Configuration
• Example: Multiple Range Configuration

Example: Range Macro Definition

This example shows how to define an interface-range macro named enet_list to select Fast Ethernet interfaces 5/1 through 5/4:

Device(config)# define interface-range enet_list fastethernet 5/1 - 4 

Example: Single Range Configuration

This example shows how to re-enable all Fast Ethernet interfaces 5/1 to 5/5:

Device(config)# interface range fastethernet 5/1 - 5 
Device(config-if-range)# no shutdown 
Device(config-if-range)#
*Oct  6 08:24:35: %LINK-3-UPDOWN: Interface FastEthernet5/1, changed state to up
*Oct  6 08:24:35: %LINK-3-UPDOWN: Interface FastEthernet5/2, changed state to up
*Oct  6 08:24:35: %LINK-3-UPDOWN: Interface FastEthernet5/3, changed state to up
*Oct  6 08:24:35: %LINK-3-UPDOWN: Interface FastEthernet5/4, changed state to up
*Oct  6 08:24:35: %LINK-3-UPDOWN: Interface FastEthernet5/5, changed state to up
*Oct  6 08:24:36: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet5/
5, changed state to up
*Oct  6 08:24:36: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet5/
3, changed state to up
*Oct  6 08:24:36: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet5/
4, changed state to up

Example: Multiple Range Configuration

This example shows how to use a comma to add different interface type strings to the range to re-enable all Fast Ethernet interfaces in the range 5/1 to 5/5 and both Gigabit Ethernet interfaces 1/1 and 1/2:

Device(config-if)# interface range fastethernet 5/1 - 5 , gigabitethernet 1/1 - 2 
Device(config-if-range)# no shutdown 
Device(config-if-range)#
*Oct  6 08:29:28: %LINK-3-UPDOWN: Interface FastEthernet5/1, changed state to up
