Configuring an ADSL WAN Interface Card on Cisco 1700 Series Routers

OL-3317-03

Configuring the ADSL Interface

This functionality is coordinated by your system administrator at the TCP/IP host site. You should not

try to use AutoInstall unless the required files are installed on the TCP/IP host.

Follow this procedure to prepare your router for the AutoInstall process:

Step 1 Connect the router to the WAN.

Step 2 Turn on power to the router.

The router loads the operating system image from Flash memory. If the remote end of the WAN

connection is connected and properly configured, the AutoInstall process begins.

Step 3 If AutoInstall succeeds, you should write the configuration data to the router’s NVRAM. To do this,

enter the copy running-config startup-config command at the Router# prompt:

Router# copy running-config startup-config

Building configuration. . .

[OK]

Router#

Note This step saves the configuration settings that the AutoInstall process created. If you do not

do this, your new configuration will be lost the next time you boot the router.

System Configuration Dialog

You can configure the router manually, using the System Configuration dialog (also called the Setup

facility). Unlike configuration mode, the System Configuration dialog prompts you for each response.

Before you begin, disconnect all WAN cables from the router to keep it from trying to run 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 configuration file stored in NVRAM. It can take several minutes

for the router to determine that AutoInstall is not connected to a remote TCP/IP host.

This section shows a sample configuration using the System Configuration dialog. You should enter

values appropriate for your router and network. To change the settings shown in the examples, and for

further information, refer to the IOS configuration guides and command references.

Many prompts in the System Configuration dialog include default answers, shown in square brackets

following the question. Enter your response, or press Return to accept the default answer.

You can request help at any time by entering a question mark (?) at the System Configuration dialog

prompt.

Follow this procedure to configure the router, using the System Configuration dialog:

Step 1 Connect a console to the router. If you need instructions for connecting a console, refer to 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]:

Press Return or enter yes to enter the System Configuration dialog.
