Reference Guide

NOTE: If authentication fails using the primary method, Dell Networking Operating System (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 Operating System
(OS) proceeds to the next authentication method. The TACACS+ is incorrect, but the user is still
authenticated by the secondary method.
After conguring the aaa authentication login command, congure 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.
