Depending on the requirement you can go ahead with configuration. I mean, ACS can be used to grant users access to devices' administration (ex: administration of Routers, Switches etc) and also for Network access (ex. access to network resources).

You can refer to following URLs:

I hope it help you to configure ACS. All the best.

These are the links for the general ACS 5.X configuration:

End-User Guides

Install and Upgrade Guides

It would be recommended to read the guide, start working your way up, once you have some issues then let us know so we can try to help you out with what we can...

thanks guys, from the sites that you have given i started the acs configuration, that works fine. But whenever i use enable i got an error message like Authentication failed.

My configuration goes like this

aaa new-model
aaa authentication login telnet_lines group tacacs+

aaa authentication enable default group tacacs+ enable----------when i use this command i got AUTHENTICATION FAILED

enable password cisco

aaa session-id common
tacacs-server host key cisco

line vty 0 4
authorization commands 15 telnet_lines
authorization exec telnet_lines
login authentication telnet_lines

guys, I am using ACS 5.0. What should i do with this?
