We just got a new Supervisor7 with os 3.4.1. I'm trying to configure authentication with tacacs, and I can't understand how to make it work. This configuration works on our other switches, but it doesn't work on this 4500.
aaa new-model username cisco privilege 15 secret 5 $1$qLGb$VQ7BdaJEpzGFqPeC979Uh1 tacacs-server host 10.4.25.8 key ourKeyIsSecret aaa authentication login default group tacacs+ local line vty 0 15 login authen default
We can only login with the fallback password. The switch is not even trying to contact tacacs.
Can anyone help?
