Cisco Systems 1800 Series Manuale Utente

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.

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 18.

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.

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:
