Description
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 time frame, 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.
The number of times the switch tries to connect to a RADIUS
server.
