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.
The Dead Time, which can be set to a number between 0
and 3600 seconds, is the period during which the switch
will not send new requests to a server that has failed to
respond to a previous request. This will stop the switch
from continually trying to contact a server that it has already
determined as dead.
Setting the Dead Time to a value greater than 0 (zero) will
