Parameter description
Common Server Configuration
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 serv-
ers are using the UDP protocol, which is unreliable by design. In order to cope with lost frames, the timeout interval is divided into 3 subin-
tervals 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.
