Options
The following section lists all possible options for the console
statement. The options that appear may vary depending on your platform and software
release.
authentication-order—Specify the order in which the authentication
methods such as password ( for local password
authentication), radius (for RADIUS server authentication),
or tacplus (for TACACS+ server authentication) should be
attempted.
authentication-methods—One or more authentication
methods, listed in the order in which they should be tried. The method can be one or
more of the following:
-
password—Use the password configured for the user with theauthenticationstatement at the[edit system login user]hierarchy level. -
radius—Use RADIUS authentication services. -
tacplus—Use TACACS+ authentication services.
disable—Disable console login connections.
insecure—Disable root login connections to the console and auxiliary
ports. Configuring the console port as insecure also prevents superusers and anyone
with a user identifier (UID) of 0 from establishing terminal connections in
multiuser mode. This option can be used to prevent a user from attempting password
recovery by booting into single-user mode, if the user does not know the root
password.

the console port is lost.
