6Configuring the Router Using Cisco Router and Security Device Manager

Cisco Router and Security Device Manager (SDM) is a web-based configuration tool that allows you to configure LAN and WAN interfaces, routing, Network Address Translation (NAT), firewalls, VPNs, and other features on your router. If SDM is installed on your router, configure the router by following the instructions in the Cisco Router and Security Device Manager (SDM) Quick Start Guide. If this document was not shipped with your router, you can obtain the SDM software and instructions for installing it on your router from the following location:

To obtain the SDM release notes and other SDM documentation, go to the following URL and click the Technical Documentation link.

7Connecting a PC to the Router Console Port

This step is optional; it is required only if you want to use the Cisco IOS CLI instead of SDM to configure or troubleshoot the router. To use Cisco IOS, you must connect the router to a terminal or to a PC with terminal emulation software. Terminal emulation software should be configured with the following settings:

9600 baud

8 data bits

No parity bits

1 stop bit

The Cisco 1800 Series Integrated Services Routers (Fixed) Software Configuration Guide describes how to configure the router by using Cisco IOS software.
