Initial Configuration
This section provides instructions for initial configuration of the Cisco 800M Series ISRs. For the initial configuration, we recommend using Cisco Configuration Professional Express. For instructions on how to use Cisco Configuration Professional Express to configure the router, see Cisco Configuration Professional Express User’s Guide.
You may also initially configure your router by using the Cisco IOS command-line interface (CLI) or by using the setup command facility. To create the initial configuration, the setup command facility prompts you for basic information about your router and network.
This section contains the following topics:
Cisco IOS CLI
To configure the initial router settings by using the Cisco IOS CLI, you must set up a console connection.
For instructions on how to set up a console connection, see the “Connecting a Terminal or PC to the Console Port” section.
Setup Command Facility
The setup command facility guides you through the configuration process by prompting you for the specific information that is needed to configure your system. Use the setup command facility to configure a hostname for the router, to set passwords, and to configure an interface for communication with the management network.
To use the setup command facility, you must set up a console connection with the router and enter the privileged EXEC mode.
Note For instructions on how to set up a console connection, see the “Connecting a Terminal or PC to the Console Port” section.
To configure the initial router settings by using the setup command facility, follow these steps:
Step 1 Set up a console connection to your router, and enter privileged EXEC mode.
Step 2 In privileged EXEC mode, at the prompt, enter setup.
The following message is displayed:
You are now in the setup command facility.
The prompts in the setup command facility vary, depending on your router model, on the installed interface modules, and on the software image. The following steps and the user entries (in bold) are shown as examples only.
Note If you make a mistake while using the setup command facility, you can exit and run the setup command facility again. Press Ctrl-C, and enter the setup command at the privileged EXEC mode prompt (Router#). For more information on using the setup command facility, see “The Setup Command” chapter in Cisco IOS Configuration Fundamentals Command Reference, Release 12.2T.
Step 3 To proceed using the setup command facility, enter yes.
Step 4 When the following messages appear, enter yes to enter basic management setup.
Step 5 Enter a hostname for the router (this example uses Router).
Step 6 Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when viewing the configuration.
Step 7 Enter an enable password that is different from the enable secret password. This password is not encrypted (less secure) and can be seen when viewing the configuration.
Step 8 Enter the virtual terminal password, which prevents unauthenticated access to the router through ports other than the console port.
Step 9 Respond to the following prompts as appropriate for your network.
A summary of the available interfaces is displayed.
Step 10 Choose one of the available interfaces for connecting the router to the management network.
Step 11 Respond to the following prompts as appropriate for your network.
The configuration is displayed:
Step 12 Respond to the following prompts. Enter 2 to save the initial configuration.
Step 13 Verify the initial configuration. See the “Verifying the Initial Configuration” section for verification procedures.
After the initial configuration file is created, you can use the Cisco IOS CLI to perform additional configuration.
Verifying the Initial Configuration
To verify that the new interfaces are operating correctly, perform the following tests:
- To verify that the interfaces and line protocol are in the correct state—up or down—enter the show interfaces command.
- To display a summary status of the interfaces configured for IP, enter the show ip interface brief command.
- To verify that you configured the correct hostname and password, enter the show configuration command.
After you complete and verify the initial configuration, you can configure your Cisco router for specific functions.
