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.

Perform Initial Configuration
You can configure your router by using one of the following tools:
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.
