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.
