The setup command facility guides you through the configuration process by prompting you for the 
specific information that is needed to configure your system. Use the setup command facility to 
configure a hostname for the router, to set passwords, and to configure an interface for communication 
with the management network.
To use the setup command facility, you must set up a console connection with the router and enter the 
privileged EXEC mode. 
NoteFor instructions on how to set up a console connection, see the “Connecting a Terminal or PC to 
the Console Port” section on page 3-16.
To configure the initial router settings by using the setup command facility, follow these steps:
Step 1Set up a console connection to your router, and enter privileged EXEC mode. For instructions on how to 
enter privileged EXEC mode, see Step 1 through Step 4 in the “Cisco IOS CLI” section on page 4-1.
