[c-nsp] TACACS+ for console problem

[ambedkar]

Hi, i am using TACACS+ for my Network. After configuring the device, if i want to login through the console, it is not taking any password and continuosly showing " Con 0 is available".

These are my commands used:
aaa new-model

aaa authentication login default group tacacs+ line

aaa authentication enable default group tacacs+ enable

aaa authorization exec default group tacacs+ if-authenticated

aaa authorization commands 15 default group tacacs+ if-authenticated

aaa accounting exec default start-stop group tacacs+

aaa accounting commands 1 default start-stop group tacacs+

aaa accounting commands 15 default start-stop group tacacs+

aaa accounting connection default start-stop group tacacs+

aaa accounting system default start-stop group tacacs+


tacacs-server host ip add.
tacacs-server key [Key].

After searching in the internet, i got one solution says use the named list as below.

aaa authentication login CONSOLE line
 &

line con 0
password cisco
line authentication CONSOLE.

With this configuration, i am able to login the switch, but it is taking the console password instead of line password which is defined in the command.

Then, i have tested the command :
aaa authentication login CONSOLE none.

Which means no authentication required, but it still asking for the password, which is console password.

Then i have removed aaa commands from config mode and line console mode.
i have used only console password. still it is working, then what is the significance of aaa commands for console.

please give your suggestions.

thanks in advance.
