Using Setup Mode to Configure a Cisco Networking Device

Setup mode provides an interactive menu to help you to create an initial configuration file for a new networking device, or a device that you have erased the startup-config file from NVRAM. The nteractive menu guides you through initial configuration and is useful when you are unfamiliar with Cisco products or the command line interface (CLI) and when configuration changes do not require the level of detail the CLI provides. Setup mode can also be used to modify an existing configuration.

This section describes how to use the System Configuration Dialog to prepare a Cisco networking device for full configuration and how you can make configuration changes after an initial configuration is complete. To improve readability, filenames are enclosed in quotation marks. Also, the terms device and networking device mean a router, switch, or other device running Cisco IOS software. The terms initial configuration and startup configuration are used interchangeably.

Prerequisites for Using Cisco IOS Setup Mode to Configure a Cisco Networking Device

  • You have read the “Basic Configuration of a Cisco Networking Device Overview” module.

  • An ASCII terminal is connected to the console port of the device being configured.

  • You know the interfaces you want to configure.

  • You know the routing protocols you want to enable.

For information about routing protocols, see the Cisco IOS IP Routing Protocols Configuration Guide , Release 12.4.

  • You know whether the device you are configuring will perform bridging.

  • You know whether the device you are configuring has protocol translation installed.

  • You have network addresses for the protocols being configured.

For information about network addresses, see the Cisco IOS IP Addressing Services Configuration Guide, Release 12.4.

  • You have a password strategy for your network environment.

For information about passwords and device security, see “Configuring Security with Passwords, Privilege Levels, and Login User names for CLI Sessions on Networking Devices” module in the Cisco IOS Security Configuration Guide, Release 12.4.

  • You have or have access to documentation for the product you want to configure.

Restrictions for Using Cisco IOS Setup Mode to Configure a Cisco Networking Device

  • Setup mode is hardware dependent. You must follow instructions for the specific product you want to configure, as described in documentation for that product.

  • Some configuration parameters apply only when a networking device has the protocol translation option. If a device does not have protocol translation, Setup does not prompt for these parameters.

Information About Using Cisco IOS Setup Mode to Configure a Cisco Networking Device

Cisco IOS Setup Mode

Cisco IOS Setup mode enables you to build an initial configuration file using the Cisco IOS CLI or System Configuration Dialog. The dialog guides you through initial configuration and is useful when you are unfamiliar with Cisco products or the CLI and when configuration changes do not require the level of detail the CLI provides.

Setup starts automatically when a device has no configuration file in NVRAM and is not preconfigured from the factory to use Cisco Router and Security Device Manager (SDM). When setup completes, it presents the System Configuration Dialog. This dialog guides you through an initial configuration with prompts for basic information about your device and network and then creates an initial configuration file. After the file is created, you can use the CLI to perform additional configuration.

Cisco Router and Security Device Manager

Cisco SDM is a web-based device management tool for configuring Cisco IOS network connections and security features on networking devices. SDM provides a default configuration and various wizards to guide you step by step through configuring a Cisco networking device, additional LAN or WAN connections, and VPN connections; creating firewalls; and performing security audits.

In addition to building an initial configuration, SDM provides an Advanced Mode through which you can configure advanced features such as Firewall Policy and Network Address Translation (NAT).

Some Cisco products ship from the factory with SDM installed. If SDM is preinstalled on your device and you want to use Setup to configure an initial configuration, you first must disable the SDM default configuration.

System Configuration Dialog

The System Configuration Dialog is an interactive CLI mode that prompts you for information needed to build an initial configuration for a Cisco networking device. Like the CLI, the System Configuration Dialog provides help text at each prompt. To access this help text, you enter a question mark (? ) at the prompt.

The prompts in the System Configuration Dialog vary depending on hardware, installed interface modules, and software image. To use the dialog for an initial configuration, you need to refer to product-specific documentation.

The values shown in square brackets next to prompts reflect the current settings. These may be default settings from the factory or the latest settings configured on the device. To accept these settings, you press Enter on the keyboard.

You can exit (Ctrl-C ) the System Configuration Dialog and return to privileged EXEC mode without making changes and without going through the entire dialog. If you exit the dialog but want to continue with setup, you can issue the setup command in privileged EXEC mode.

When you complete all the steps in the dialog, the device displays the modified configuration file and asks if you want to use that file. You must answer yes or no; there is no default for this prompt. If you answer yes, the file is saved to NVRAM as the startup configuration. If you answer no, the file is not saved and you must start at the beginning of the dialog if you want to build another initial configuration.

In addition to being a quick and easy way to perform an initial configuration, the System Configuration Dialog also is useful for performing basic configuration changes after an initial configuration has been performed.

Benefits of Using Cisco IOS Setup Mode

The System Configuration Dialog in Cisco IOS Setup mode can be a valuable tool for users who are unfamiliar with Cisco products or the CLI. The dialog guides users through the configuration process with prompts for basic information to get the device operational. When general configuration changes are needed, the dialog also is an alternative method to the detail-level CLI.

What to Do Next

Proceed to the “Verifying the Configuration” section.

Using the System Configuration Dialog to Make Configuration Changes

The System Configuration Dialog is an alternative to the CLI when configuration changes do not require the level of detail the CLI provides. For example, you can use the System Configuration Dialog to add a protocol suite, make addressing scheme changes, or configure a newly installed interface. Although you can use configuration modes available through the CLI to make these changes, the System Configuration Dialog provides you a high-level view of the configuration and guides you through the configuration process.

Before you begin

When you add or modify hardware and need to update a configuration, refer to documentation for your platform for details about physical and logical port assignments.


Note

The System Configuration Dialog does not allow you to randomly select or enter parameters for configuration. You must move through the dialog step by step until the screen shows the information you want to change.
