Configuring Dial Backup and Remote Management Through a V.92 Modem

Perform the following tasks to configure dial backup and remote management through the V.92 modem on your Cisco 1811 router:

•Asynchronous Interface Configuration

•Line Configuration

Asynchronous Interface Configuration

Perform these steps to configure the V.92 modem for use as a backup interface, beginning in global configuration mode:

	Command	Purpose
Step 1
	interface type number	Enters interface configuration mode for the
		asynchronous serial interface. Enter the number of
	Example:	the interface you want to configure.
	Router(config)# interface async 1
	Router(config-if)#
Step 2	ip unnumbered type number	Conserves IP addresses by configuring the
		asynchronous interface as unnumbered, and
	Example:	assigns the IP address of the interface type that
	Router(config-if)# ip unnumbered	you want to leverage.
	FastEthernet 2
	Router(config-if)#
Step 3	encapsulation encapsulation-type	Sets the encapsulation type to PPP for the
		interface.
	Example:
	Router(config-if)# encapsulation ppp
	Router(config-if)#
