Configuring LAN Interfaces

Configuring a LAN Extender Interface

Shutting Down and Restarting the LAN Extender’s Ethernet Interface

From the core router, you can shut down the LAN Extender’s Ethernet interface. This stops traffic on the remote Ethernet LAN from reaching the core router, but leaves the LAN Extender interface that you created intact.

Note There are no commands that allow you to shut down the serial interface on the LAN

Extender.

To shut down the LAN Extender’s Ethernet interface, use the following command in interface configuration mode:

Command

shutdown

Purpose

Shuts down the LAN Extender’s Ethernet interface.

To restart the LAN Extender’s Ethernet interface, use the following command in interface configuration mode:

Command

no shutdown

Purpose

Restarts the LAN Extender’s Ethernet interface.

Restarting the LAN Extender

To reboot the LAN Extender and reload the software, use one of the following commands in privileged EXEC mode:

Command

Purpose

 

 

 

clear

controller lex number [prom]

Halts operation of the LAN Extender and initiates a cold restart.

 

 

 

clear

controller lex slot/port [prom]

Halts operation of the LAN Extender on a Cisco 7000 series routers.

 

 

 

Downloading a Software Image to the LAN Extender

When the LAN Extender is powered on, it runs the software image that is shipped with the unit. You can download a new software image from a TFTP server or from Flash memory on the core router to the LAN Extender.

To download a software image to the LAN Extender, use one of the following commands in privileged EXEC mode:

Command

Purpose

 

 

 

copy

tftp lex number

Downloads a software image from a TFTP server.

 

 

 

copy

flash lex number

Downloads a software image from Flash memory.
