Users Guide

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 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.
