The page includes the following fields:
Object Description
• RADIUS Server IP
The IP address or hostname of the RADIUS Authentication Server. IP address is
expressed in dotted decimal notation.
• Auth Port
The UDP port to use on the RADIUS Authentication Server. If the port is set to 0
(zero), the default port (1812) is used on the RADIUS Authentication Server.
• Acct Port
The UDP port to use on the RADIUS Accounting Server. If the port is set to 0
(zero), the default port (1813) is used on the RADIUS Accounting Server.
• Server Key
• (max. 30 characters)
The shared key - up to 30 characters long - shared between the RADIUS
Authentication Server and the switch.
• Server 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.
