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
Step1 interface type number
Example:
Router(config)# interface async 1
Router(config-if)#
Enters interface configuration mode for the
asynchronous serial interface. Enter the number of
the interface you want to configure.
Step2 ip unnumbered type number
Example:
Router(config-if)# ip unnumbered
FastEthernet 2
Router(config-if)#
Conserves IP addresses by configuring the
asynchronous interface as unnumbered, and
assigns the IP address of the interface type that
you want to leverage.
Step3 encapsulation encapsulation-type
Example:
Router(config-if)# encapsulation ppp
Router(config-if)#
Sets the encapsulation type to PPP for the
interface.
