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.
RADIUS Authentication Server Configuration
The table has one row for each RADIUS Authentication Server and a number of columns, which are:
Object
Description
#
