Usage Information
By default, the Enable password is used. If you congure aaa authentication enable default, Dell
Networking OS uses the methods dened for Enable access instead.
Methods congured with the aaa authentication enable command are evaluated in the order they are
congured. If authentication fails using the primary method, Dell Networking OS employs the second method (or
third method, if necessary) automatically. The fallback to the second method would happen only if the
authentication failure is due to a non-reachable server or invalid TACACS server key. The fallback would not occur
if the authentication failure is due to invalid credentials. For example, if the TACACS+ server is reachable, but the
server key is invalid, Dell Networking OS proceeds to the next authentication method.
