Configuration Changes

This section describes how to configure the router. It includes information on the following topics:

•setup Command Interactive Script Example, page 3-54

•Configuring Global Parameters, page 3-57

•Configuring Network Interfaces, page 3-58

•Checking the Software Version, page 3-61

•Verifying the Running Configuration Settings, page 3-62

•Saving the Running Configuration Settings to NVRAM, page 3-64

•Reviewing the Running Configuration Settings, page 3-64

During the first-time startup of an unconfigured router, the system automatically starts the setup command utility and begins displaying the interactive System Configuration Dialog on the system console screen. The System Configuration Dialog guides you through the configuration process with prompts for global (system-wide) parameters and interface (line card) parameters.

The System Configuration Dialog prompts and the order in which they appear on the screen vary depending on the platform, interfaces installed, router, and the Cisco IOS software image the router is running.

Let the entire System Configuration Dialogue script run, until you come to the item that you want to change. To accept default settings for items that you do not want to change, press the console keyboard Return key. To return to the privileged EXEC prompt without making changes, press Ctrl-C. To access help text in the setup command utility, press the question mark key (?) at any prompt.

When you complete your changes, the setup command utility displays the configuration command script that was created as a result of the changes entered during the setup session. It also queries if you want to use this configuration. If you answer Yes, the configuration is saved to NVRAM. If you answer No, the configuration is not saved and the process begins again. There is no default for this prompt; you must answer either Yes or No.

The “setup Command Interactive Script Example” section on page 3-54, shows a setup session automatically invoked during the first-time startup of the router. During first-time startup, the system displays the system banner information, then starts the System Configuration Dialog.
