configure AAA authentication on router in packet tracer step by step
In this video , I will show you how to configure AAA authentication on a Cisco IOS router. We will use a TACAS+ server. Once everything is configured, a user that wants to access the console and use privileged mode will be authenticated by the TACAS server.
Locally configured usernames and passwords can become an administrative nightmare if you have a network with many network devices. Each time you want to add a username or change a password, you have to log in each device one-by-one to add or change something. It’s a better idea to work with a central AAA server for authentication. On this server, you add all your usernames and passwords. You configure your routers and switches to use this AAA server for authentication.
