Configuring a LAN Extender Interface

LAN Extender Interface Configuration Task List

To configure a LAN Extender interface, perform the tasks described in the following sections:

•Configuring and Creating a LAN Extender Interface (Required)

•Defining Packet Filters (Optional)

•Controlling Priority Queueing (Optional)

•Controlling the Sending of Commands to the LAN Extender (Optional)

•Shutting Down and Restarting the LAN Extender’s Ethernet Interface (Optional)

•Restarting the LAN Extender (Optional)

•Downloading a Software Image to the LAN Extender (Optional)

•Troubleshooting the LAN Extender (Optional)

To monitor the LAN Extender interface, see the “Monitoring and Maintaining the Interface” section in the “Interface Configuration Overview” chapter. For configuration examples, see the “LAN Extender Enablement Interface Example” and the “LAN Extender Interface Access List Examples” sections.

Configuring and Creating a LAN Extender Interface

To configure and create a LAN Extender interface, you configure the LAN Extender interface itself and the serial interface to which the LAN Extender is physically connected. The order in which you configure these two interface interfaces does not matter. However, you must first configure both interfaces in order for the LAN Extender interface to bind (associate) to the serial interface.

To create and configure a LAN Extender interface, use the following commands starting in interface configuration mode:

	Command	Purpose
Step 1
	interface lex number	Configures a LAN Extender interface in global configuration mode and
		enters interface configuration mode.
		or
	interface lex slot/port	Configures a LAN Extender on a Cisco 7000 series routers.
Step 2
	lex burned-in-address ieee-address	Assigns the burned-in MAC address from your LAN Extender to the
		LAN Extender interface.
Step 3
	ip address ip-address mask	Assigns a protocol address to the LAN Extender interface.
Step 4
	exit	Returns to global configuration mode.
Step 5
	interface serial number	Configures a serial interface in global configuration mode and enters
		interface configuration mode.
Step 6
	encapsulation ppp	Enables PPP encapsulation on the serial interface in interface
		configuration mode.
Step 7
	Ctrl-Z	Exits interface configuration mode.
Step 8
	copy system:running-config	Saves the configuration to memory.
	nvram:startup-config

Note that there is no correlation between the number of the serial interface and the number of the LAN Extender interface. These interfaces can have the same or different numbers.
