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.
 Dead Time 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 enable this feature, but
only if more than one server has been configured.
