This guide is intended for network administrators whose backgrounds vary from having no or little 
experience in configuring routers to having a high level of experience. You can use this guide in the 
following situations:

You have configured the software by using the Cisco Router Web Setup tool, and you want to 
configure additional advanced software features by using the command-line interface (CLI).

You want to configure the software using only the CLI.

We strongly recommend that network administrators with minimal familiarity with Cisco routers use the 
Cisco Router and Security Device Manager (SDM)—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. To obtain the SDM release notes and other SDM documentation, go to 

 and click the Technical Documentation link.
