The page includes the following fields:

Port State

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.

RADIUS Authentication Server Configuration

The table has one row for each RADIUS Authentication Server and a number of columns, which are:
