AAA Authentication - Please Help! 🙏

[msrbelfast]

Hi, I'm hoping someone out there can help me before my head disintegrates!

I have this Packet Tracer file, link below, that has a (probably very slight) error with the AAA configuration... but I haven't a scooby-doo what the problem is. I'm literally on the floor begging you, but not in a way that I'll loose my job or anything, or see the kids starve... I don't work in this industry. It's just doing my head in.

Hi @msrbelfast 

 Hope you have you head on yet.

I manage to make it to work with small chaning. Actually I fixed the SW2 only but I believe you can move forward with the rest.

On the below command you was using the switch IP address while you should use the TACACS IP address

tacacs-server host 192.168.10.2 key ciscosecret

The line in the begining of the configuration

aaa authentication login telnet_lines group tacacs+

must reflect the line at the end of the configuration

line vty 0 4

login authentication telnet_lines

Last but not least, the configuration on the server side must be TACACS and not radius.
