Description: In this article about aaa login, the author is going to show how to configure authentication for the console port on a Cisco router using AAA authentication. The AAA server typically interacts with network access and gateway servers and with databases and directories containing user information.
Let’s begin by going to our router, we will enter the basic commands to get an authentication for Console, the first step would be to go to my router login, I’ll get to the global configuration, I’ll type the command config T, this moves me to the global configuration mode.
The next step would be to issue the triple a new model command, a fact of doing this command could inadvertently lock you out of your Cisco router, so be very careful in a label in this command, the next thing I’m going to do is to create a username.
We’ll use the username command bill password, the next step would be to set there and go to their line and Affairs or to invoke the login, from here I’m going to go to the line con 0, I’m going to type in password Cisco, then I’m going to evoke login.
This command is doing this logging using their local user database, hit enter, it doesn’t like this command, let’s use a question mark here, I’ll have to do the authentication local, I can’t do it local because it couldn’t fire that, I’ll have to come back and define that I put in authentication long.
As you can see I’ve got my aaa authentication login default local, I’ve got my username bill, we’ll go down and see the line con 0, let’s verify this and make sure that it works, everything is going to prompt me for a username and the password.
I get back into global configuration, I’ll supply that password, they’re back in, now that I’ve verified it, I can wipe this the memory, there will be a couple of ways we can do this, thanks.
