Reference Guide

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.
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.
