Perform Initial Configuration | Cisco Systems 1800 specification

Note On the Cisco 1841 router, the numbering format for configuring an async interface is 0/slot/port. To configure the line associated with an async interface, simply use the interface number to specify the async line. For example, line 0/0/0 specifies the line associated with interface serial 0/0/0 on a WIC-2A/S in slot 0. Similarly, line 0/1/1 specifies the line associated with interface async 0/1/1 on a WIC-2AM in slot 1.

8Perform Initial Configuration

You can configure your router by using one of the following tools:

•Cisco Router and Security Device Manager (SDM)—See the “Initial Configuration Using Cisco Router and Security Device Manager” section on page 17.

•Setup command facility—See the “Initial Configuration Using Setup Command Facility” section on page 17.

•Command-line interface (CLI)—See the “Initial Configuration Using Cisco CLI—Manual Configuration” section on page 20.

Initial Configuration Using Cisco Router and Security Device Manager

If the following messages appear at the end of the startup sequence, Cisco Router and Security Device Manager (SDM) is installed on your router:

yourname con0 is now available

Press RETURN to get started.

For instructions on configuring your router by using SDM, refer to the Cisco Router and Security Device Manager (SDM) Quick Start Guide that shipped with your router.

Tip If the messages above do not appear, SDM and the Cisco Router and Security Device Manager (SDM) Quick Start Guide were not shipped with your router. If you want to use SDM, you can download the latest version of SDM and instructions for installing it on your router from the following location:

http://www.cisco.com/pcgi-bin/tablebuild.pl/sdm

To obtain the SDM quick start guide, SDM release notes, and other SDM documentation, go to www.cisco.com/go/sdm and click the Technical Documentation link.

Initial Configuration Using Setup Command Facility

This section shows how to use the setup command facility to configure a hostname for the router, set passwords, and configure an interface for communication with the management network.

If the following messages appear at the end of the startup sequence, the setup command facility has been invoked automatically:

--- System Configuration Dialog ---

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 '[]'.

Would you like to enter the initial configuration dialog? [yes/no]:

The setup command facility prompts you for basic information about your router and network, and it creates an initial configuration file. After the configuration file is created, you can use the CLI or Cisco Router and Security Device Manager to perform additional configuration.
