servers are unavailable. Additionally, users who are configured locally but are not configured on the
RADIUS server are still able to log into the device. Authentication methods are attempted in the order
they are listed until the first successful authentication result is returned; therefore if you want to
ensure that users are authenticated first through the RADIUS server, and only authenticated locally if
the RADIUS server is unavailable or if the user is not defined on the RADIUS server, then you should
list the RADIUS authentication method prior to the Local users authentication method.
See User authentication methods for more information about authentication methods.
If the RADIUS servers are unavailable and the IX14 device falls back to local authentication, only users
defined locally on the device are able to log in. RADIUS users cannot log in until the RADIUS servers
are brought back online.
