Initial Configuration Using the Command-Line Interface
This section briefly describes how to display a command-line interface (CLI) prompt for configuration
using the CLI.
You can use the CLI if the following messages appear at the end of the startup sequence:
--- System Configuration Dialog ---
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Would you like to enter the initial configuration dialog? [yes/no]:
If these messages do not appear, SDM and a default configuration file were installed on the router at the
factory. To use SDM to configure the router, see the “Initial Configuration Using the Cisco Router and
Security Device Manager” section on page 3.
To perform initial configuration using the CLI, follow these steps, beginning in privileged EXEC mode:
Note Be sure to save your configuration changes occasionally so that they are not lost during resets, power
cycles, or power outages. Use the copy running-config startup-config command at the privileged
EXEC mode prompt (Router#) to save the configuration to NVRAM.
Step 1 To proceed with manual configuration using the CLI, enter no when the power-up messages end:
Would you like to enter the initial configuration dialog? [yes/no]: no
Step 2 Press Return to terminate autoinstall and continue with manual configuration:
Would you like to terminate autoinstall? [yes] Return
Several messages appear, ending with a line similar to the following:
