Parameter description:
Timeout :

The Timeout, which can be set to a number between 3 and 3600 seconds, is the maximum
time to wait for a reply from a server.
If the server does not reply within this timeframe, we will consider it to be dead and
continue with the next enabled server (if any).
RADIUS servers are using the UDP protocol, which is unreliable by design. In order to
cope with lost frames, the timeout interval is divided into 3 subintervals of equal length. If a
reply is not received within the subinterval, the request is transmitted again. This algorithm
causes the RADIUS server to be queried up to 3 times before it is considered to be dead.
