Where to Go from Here

The "First-Time Startup" chapter described how to get your router started for the first time using the setup command facility. This chapter describes the following tasks:

For information about using the EXEC command interpreter, refer to the Router Products Configuration Guide. For information about specific commands, refer to the Router Products Command Reference publication. For information about configuring protocol translation, refer to the publication Protocol Translation Configuration Guide and Command Reference.

Using the Setup Command after First-Time Startup

You can use the setup command facility after first-time startup to make basic configuration changes at any time. The changes you make affect only the changed elements in current running memory and in nonvolatile memory (NVRAM).

To run the setup command facility, enter the following command from privileged EXEC mode. (Your router's host name followed by a pound symbol (#) signals that you are in privileged EXEC mode.)

Router#setup
Note If you are not already in privileged
EXEC mode, you must enter it using the enable command. Refer to the "Understanding the User Interface" chapter of the Router Products Configuration Guide for instructions on entering the privileged EXEC mode. The enable command requires you to enter the enable password you specified during setup. If you do not remember the enable password, refer to the "Managing the System" chapter of the Router Products Configuration Guide for instructions on recovering a lost enable password.

When you enter the setup command facility after first-time startup, you must run through the entire dialog until you come to the element you intend to change. The default values shown in brackets are the values last set using the setup command facility or using the configure command. Refer to the "Preparing for First-Time Startup" chapter for complete descriptions of the values you can enter during the setup command facility dialog.

To return to the privileged EXEC prompt without making changes and without running through the entire System Configuration Dialog, press Ctrl-C.

Using the Streamlined Setup Command Facility

The streamlined setup command facility is available only if your router is running from ROM monitor and has RXBOOT ROMs installed. The following routers can have this type of ROM installed:

The streamlined setup command facility permits your router to load a system image from a network server when there are problems with the configuration in NVRAM. The IOS software automatically puts you in the streamlined setup command facility when your router is accidentally or intentionally rebooted (or you are attempting to load a system image from a network server) after any of the following circumstances:

The streamlined setup command facility differs from the standard setup command facility in that the streamlined facility does not ask you to configure global router parameters. You are prompted only to configure interface parameters, which permit your router to boot.

Example

The following example shows a router entering the streamlined setup command facility:

--- System Configuration Dialog --- Refer to the 'Getting Started' Guide for additional help. Default settings are in square brackets '[]'. Configuring interface IP parameters for netbooting:
Note The message
"Configuring interface IP parameters for netbooting" only appears if you are netbooting and your configuration has insufficient IP information.
  The streamlined setup command facility continues by prompting you for interface parameters for each installed interface. The facility asks if an interface is in use. If so, the facility then prompts you to provide an IP address and subnet mask bits for the interface. Enter the subnet mask bits as a decimal value, such as 5. The following example shows the portion of the streamlined setup command facility that prompts for interface parameters. In the example, the facility is prompting for Ethernet0 interface parameters and Serial0 interface parameters:
Configuring interface Ethernet0: Is this interface in use? [yes]: Configure IP on this interface? [yes]: IP address for this interface: 192.195.78.50 Number of bits in subnet field [0]: 5 Class C network is 192.195.78.0, 5 subnet bits; mask is 255.255.255.248 Configuring interface Serial0: Is this interface in use? [yes]: Configure IP on this interface? [yes]: IP address for this interface: 192.195.78.34 Number of bits in subnet field [5]: Class C network is 192.195.78.0, 5 subnet bits; mask is 255.255.255.248

The system then displays the command script that was created as a result of your configuring the router through the streamlined setup command facility.

The configuration information you provide on this screen is temporary and exists only so that you can proceed with booting your system. When you reload the system, your original configuration is left intact. If your image in NVRAM is corrupted, enter the setup command facility, and configure the basic parameters. Then issue the write memory command to write this configuration to NVRAM. Refer to the Router Products Configuration Guide for further details.

Reviewing Your Configuration Changes

You can review the changes you made to the configuration. To display information stored in NVRAM, use the EXEC command show configuration.

Implementing Other Configuration Tasks

After you establish the basic startup configuration for your router, refer to the Router Products Configuration Guide or the Router Products Command Reference publication for information on using the configure command to make advanced configuration changes.

The configuration guide also provides information about the following tasks:

To configure your router for protocol translation, refer to the publication Protocol Translation Configuration Guide and Command Reference.
