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 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.
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.
