Figure 4-9-11 New Radius Server Page Screenshot
The page includes the following fields:
Object Description
 Server Definition Set the server definition
 Server IP Address of the Radius server IP/name
 Authetication 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.
 Key String The shared key - shared between the RADIUS Authentication Server and the
switch.
 Timeout for Reply The Timeout, which can be set to a number between 1 and 30 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.
 Retries Timeout is the number of seconds, in the range 1 to 10, to wait for a reply from a
RADIUS server before retransmitting the request.
