Common Server Configuration
These setting are common for all of the Authentication Servers.
Label
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:
Label
Description
#
The RADIUS Authentication Server number for which the
configuration below applies.
Enable
Enable the RADIUS Authentication Server by checking this box.
IP Address
Enable fallback to local authentication by checking this box.
If none of the configured authentication servers are alive, the local
user database is used for authentication.
This is only possible if the Authentication Method is set to
something else than 'none or 'local'.
