Chapter 3 Starting and Configuring the Router Configuring a Cisco 7201 Router
The ENABLED LED on the port adapter goes on when initialization is completed, and the console
screen displays a script and system banner similar to the following:
Cisco IOS Software, 7200 Software (C7200P-ADVENTERPRISEK9-M), Version
12.4(7201XD.2006-12-03), INTERIM SOFTWARE

Step 5 When you start up the router for the first time, the system automatically enters the setup facility, which
determines which port adapter is installed and prompts you for configuration information. On the
console terminal, after the system displays the system banner and hardware configuration, you will see
the following System Configuration Dialog prompt:
--- System Configuration Dialog ---
At any point you may enter a questions mark ‘?’ for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets ‘[]’.
continue with configuration dialog? [yes]:
You have the option of proceeding with the setup facility to configure the interfaces, or exiting from
setup and using configuration commands to configure global (system-wide) and interface-specific
parameters. You do not have to configure the interfaces immediately; however, you cannot enable the
interfaces or connect them to any networks until you have configured them.
Many of the port adapter LEDs do not go on until you have configured the interfaces. To verify correct
operation of each interface, complete the first-time startup procedures and configuration, and then refer
to the configuration note for the port adapter for LED descriptions and to check the status of the
interfaces.
If the system does not complete each of the steps in the startup procedure, proceed to Chapter 5,
“Troubleshooting Initial Startup Problems” for troubleshooting recommendations and procedures.
Configuring a Cisco 7201 Router
You can configure your Cisco 7201 router using one of the procedures described in the following
sections:
• Performing a Basic Configuration Using AutoInstall, page 3-10
• Performing a Basic Configuration Using the Setup Facility, page 3-10
• Performing a Basic Configuration Using Global Configuration Mode, page 3-20
Follow the procedure that best fits the needs of your network configuration.
Note You need to acquire the correct network addresses from your system administrator or consult your
network plan to determine correct addresses before you can complete the router configuration.
Before continuing the configuration process, check the current state of the router by entering the show
version command. The show version command displays the release of Cisco IOS software that is
available on the router. Sample output of the show version command appears in the “Viewing Your
System Configuration” section on page 3-29.
