These setting are common for all of the Authentication Servers.
Object 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 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.
• 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.
