Per security aaa will not allow you to use the line password.

Please add a local user and use that local user for authentication.

usernamer xxxx privilege 15 password xxxx.

Ad an user and authenticate with that one.

Hi Wasim,

For aaa configuration in console check out the below configuration for console authentication

aaa authentication login CONSOLE line

There is only one authentication method (line).
Once a named list (in this example, CONSOLE) is created, it must be applied to a line or interface for it to come into effect. This is done using the

login authentication list_name command:
      line con 0
          exec-timeout 0 0
          password cisco
          login authentication CONSOLE

The CONSOLE list overrides the default method list default on line con 0.

Note: To have console access authenticated by a local username and password, use:

    aaa authentication login CONSOLE local

Note: In this case, a username and password have to be configured in the local database of the router. The list must also be applied to the line or interface.

Note: To have no authentication, use

    aaa authentication login CONSOLE none

Note: In this case, there is no authentication to get to the console access. The list must also be applied to the line or interface.

Hope that helps out your query !!
