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.
