Usage
Information
By default, the locally configured username password is used. If you configure aaa
authentication login default
, Dell Networking OS uses the methods this
command defines 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, Dell Networking OS 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 is not entered, the user
is not allowed access to the switch.
NOTE: If authentication fails using the primary method, Dell Networking OS
employs the second method (or third method, if necessary) automatically. For
example, if the TACACS+ server is reachable, but the server key is invalid, Dell
Networking OS proceeds to the next authentication method. The TACACS+ is
incorrect, but the user is still authenticated by the secondary method.
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.
