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.

How to Use Cisco IOS Setup Mode to Configure a Cisco Networking Device and Make Configuration Changes

This section describes how to use the System Configuration Dialog to build an initial configuration file and to make configuration changes after a startup configuration has been loaded.

Disabling the SDM Default Configuration File

Perform this task if SDM was preinstalled on your device and you want to use Setup to build an initial configuration file. SDM remains on the device.

Perform this task if SDM was pre installed on your device and you want to use AutoInstall to configure the device instead. SDM remains on the device.

      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.


      SUMMARY STEPS

          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.

          How to Use Cisco IOS Setup Mode to Configure a Cisco Networking Device and Make Configuration Changes

          This section describes how to use the System Configuration Dialog to build an initial configuration file and to make configuration changes after a startup configuration has been loaded.

          Disabling the SDM Default Configuration File

          Perform this task if SDM was preinstalled on your device and you want to use Setup to build an initial configuration file. SDM remains on the device.

          Perform this task if SDM was pre installed on your device and you want to use AutoInstall to configure the device instead. SDM remains on the device.

          SUMMARY STEPS

            1.    Connect the console cable, shipped with your device, from the console port on the device to a serial port on your PC. Refer to the hardware installation guide for the device for instructions.

            2.    Connect the power supply to the device, plug the power supply into a power outlet, and turn on the device. Refer to the quick start guide for the device for instructions.

            3.    Use Hyperterminal or a similar terminal emulation program on your PC, with the following terminal emulation settings, to connect to the device:

            4.    enable

            5.    erase startup-config

            6.    reload


          DETAILED STEPS
            Step 1   Connect the console cable, shipped with your device, from the console port on the device to a serial port on your PC. Refer to the hardware installation guide for the device for instructions.
            Step 2   Connect the power supply to the device, plug the power supply into a power outlet, and turn on the device. Refer to the quick start guide for the device for instructions.
            Step 3   Use Hyperterminal or a similar terminal emulation program on your PC, with the following terminal emulation settings, to connect to the device:
            • 9600 baud

            • 8 data bits, no parity, 1 stop bit

            • No flow control

            Step 4   enable

            Enter privileged EXEC mode.

            enable



            Example:
            Router> enable
            Router#
            
            Step 5   erase startup-config

            Erases the existing configuration in NVRAM.



            Example:
            Router# erase startup-config
            
            Step 6   reload

            Initiates the reload process. The router will initiate the AutoInstall process after it finishes the reload process.



            Example:
            Router# reload
            

            Using the System Configuration Dialog to Create an Initial Configuration File

            Perform this task to create an initial configuration for a Cisco networking device.

            Before You Begin

            If SDM is installed, you must disable its default configuration file before using Setup.


            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.

              The screen displays the following:
              The enable secret is a password used to protect access to
                privileged EXEC and configuration modes. This password, after
                entered, becomes encrypted in the configuration.
                Enter enable secret: 
              
              Step 6   Enter an enable secret password. This password is encrypted and cannot be seen when viewing the configuration.

              Example:
              Enter enable secret: 1g2j3mm
              

              The screen displays the following:



              Example:
              The enable password is used when you do not specify an
                enable secret password, with some older software versions, and
                some boot images.
                Enter enable password: 
              
              Step 7   Enter an enable password that is different from the enable secret password. An enable password is not encrypted and can be seen when viewing the configuration:

              Example:
                Enter enable password: cts54tnl
              

              The screen displays the following:



              Example:
              The virtual terminal password is used to protect
                access to the router over a network interface.
                Enter virtual terminal password: 
              
              Step 8   Enter a virtual terminal password. This password allows access to the device through only the console port.

              Example:
                Enter virtual terminal password: tls6gato
              

              The screen displays the following:



              Example:

              Enter interface name used to connect to the
              management network from the above interface summary:
              
              Step 10   Select an interface to connect the router to the management network:

              Example:
              Enter interface name used to connect to the
              management network from the above interface summary: Ethernet0/0
              
              Step 11   Respond to the prompts as appropriate for your network. In this example, IP is configured: an IP address is entered and the current subnet mask is accepted. The screen displays the command script created.

              Example:
              Configuring interface Ethernet0/0:
                Configure IP on this interface? [no]: yes

              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.


              SUMMARY STEPS

                1.    enable

                2.    setup

                3.    Follow Steps 3 through 12 in the Detailed Steps in the preceding “Using the System Configuration Dialog to Create an Initial Configuration File” section on page 5 .

                4.    Verify the configuration is modified correctly. Refer to the “Verifying the Configuration” section.


              DETAILED STEPS
                Step 1   enable

                The enable command enters privileged EXEC mode.



                Example:
                Router> enable
                Router#
                
                Step 2   setup

                The setup command puts the router in setup mode.



                Example:
                Router# setup

                Verifying the Configuration

                Perform this task to verify that the configuration you created using the System Configuration Dialog is operating correctly.

                SUMMARY STEPS

                  1.    show interfaces

                  2.    show ip interface brief

                  3.    show configuration


                DETAILED STEPS
                  Step 1   show interfaces

                  This command verifies that the interfaces are operating correctly and that they and the line protocol are in the correct state: up or down.

                  Step 2   show ip interface brief

                  This command displays a summary status of the interfaces configured for IP.

                  Step 3   show configuration

                  This command verifies that the correct hostname and password were configured.


                  Example

                  This example is the verification of the configuration file created in the “Using the System Configuration Dialog to Create an Initial Configuration File” section.

                  Configuration Examples for Using Cisco IOS Setup Mode to Configure a Cisco Networking Device

                  Example Configuring Ethernet Interface 0 Using the System Configuration Dialog

                  In the following example, the System Configuration Dialog is used to configure Ethernet interface 0 with an IP address.


                  Note


                  Prompts and the order in which they appear on the screen vary depending on the platform and the interfaces installed in the device.


                  R1# setup
                  --- System Configuration Dialog ---
                  Continue with configuration dialog? [yes/no]: yes
                  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 '[]'.
                  Basic management setup configures only enough connectivity
                  for management of the system, extended setup will ask you
                  to configure each interface on the system
                  Would you like to enter basic management setup? [yes/no]: yes
                  Configuring global parameters:
                    Enter host name [R1]: Router
                    The enable secret is a password used to protect access to
                    privileged EXEC and configuration modes. This password, after
                    entered, becomes encrypted in the configuration.
                    Enter enable secret: 1g2j3mmc
                    The enable password is used when you do not specify an
                    enable secret password, with some older software versions, and
                    some boot images.
                    Enter enable password: cts54tnl
                    The virtual terminal password is used to protect
                    access to the router over a network interface.
                    Enter virtual terminal password: tls6gato
                    Configure SNMP Network Management? [no]:
