Configuring an ADSL WAN Interface Card on Cisco 1700 Series Routers
OL-3317-03
Configuring the ADSL Interface
Before you begin, disconnect all WAN cables from the router to keep it from running the AutoInstall
process. The router tries to run AutoInstall whenever you power it on if there is a WAN connection on
both ends and the router does not have a valid configuration file stored in NVRAM (for instance, when
you add a new interface). It can take several minutes for the router to determine that AutoInstall is not
connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.
To enter configuration mode, follow this procedure:
Step 1 Connect a console to the router. If you need instructions for connecting a console, refer to the
installation chapter of your router installation and configuration guide. Power up the router.
Step 2 If the current configuration is no longer valid, after about one minute you see the following prompt:
Would you like to enter the initial dialog? [yes]:
Enter no. You now enter the normal operating mode of the router.
Note If the current configuration is valid, you enter the normal operating mode automatically.
Step 3 After a few seconds, you see the user EXEC prompt. Type enable and the password to enter enable
mode:
Router> enable
Password:
Configuration changes can be made only in enable mode. The prompt changes to the privileged EXEC
(enable) prompt (
Router#):
Router#
Step 4 Enter the config terminal command to enter configuration mode:
Router# config terminal
Router(config)#
The router enters global configuration mode, indicated by the Router(config)# prompt.
Step 5 If you have not configured the router before or want to change the configuration, you can configure
global parameters, passwords, network management, and routing protocols. In this example, IP routing,
AppleTalk routing, and Internetwork Packet Exchange (IPX) routing are all enabled:
Router(config)# ip routing
Router(config)# appletalk routing
Router(config)# ipx routing
For complete information about global configuration commands, refer to the IOS configuration guides
and command references.
Step 6 Select the ADSL interface to configure:
Router(config)# interface atm 0
Router(config-if)#
The prompt changes again to show that you are in interface configuration mode.
Note For the Cisco 1751 and 1760 routers, enter the command as interface atm slot/port. For
example, interface atm 0/0.
Step 7 Select the ADSL operating mode:
