Usage
Information
By default, the locally configured username password is used. If you configure aaa authentication
login default, Dell EMC 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 EMC 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 EMC 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 EMC 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.
