Usage
By default, the locally configured username password is used. If you configure aaa
Information
authentication login default, FTOS uses the methods defined by this command
for login instead.
Methods configured with the aaa authentication login command are evaluated in
the order they are configured. If users encounter an error with the first method listed, FTOS
applies the next method configured. If users fail the first method listed, no other methods are
applied. The only exception is the local method. If the user's name is not listed in the local
database, the next method is applied. If the correct user name/password combination are not
entered, the user is not allowed access to the switch.
After configuring the aaa authentication login command, configure the login
authentication command to enable the authentication scheme on terminal lines.
Connections to the SSH server work with the following login mechanisms: local, radius, and
tacacs.

(OPTIONAL) Enter up to four additional methods. In the event of a "no
response" from the first method, FTOS applies the next configured
method (up to four configured methods).

NOTE: If authentication fails using the primary method, FTOS employs the second method
(or third method, if necessary) automatically. For example, if the TACACS+ server is
reachable, but the server key is invalid, FTOS proceeds to the next authentication method.
The TACACS+ is incorrect, but the user is still authenticated by the secondary method.
