sir, for duble redundancy, we have to write the command in Single line. But here, you can see Two seperate line. And one thing more, in Console, only Auth with None is used? What does it mean ?

your aaa authentication is set in a hierarchical method:

it will first try method 1:

aaa authentication login default line

> this means that a user authenticates using the password set on your line (console, aux or vty)

if method 1 is not met, it checks method 2:

aaa authentication login NO_AUTH none

> 'none' means no authentication is required or you automatically login into the device. the NO_AUTH is then applied to your console line

you can write an alternative single command using:

aaa authentication login {default | list-name} method1 [method2...]

aaa authentication login default NO_AUTH line none
