Description
Specify the type of the RADIUS server supported by the device,
including:

extended: Specifies an extended RADIUS server (usually a
CAMS or iMC server). That is, the RADIUS client and RADIUS
server communicate using the proprietary RADIUS protocol and
packet format.

standard: Specifies a standard RADIUS server. That is, the
RADIUS client and RADIUS server communicate using the
standard RADIUS protocol and packet format defined in RFC
2138/2139 or later.
Specify and confirm the shared key for the authentication server.
These two parameters must have the same values.
Specify and confirm the shared key for the accounting server. These
two parameters must have the same values.
Specify the source IP address for the device to use in RADIUS packets
to be sent to the RADIUS server. It is recommended to use a loopback
interface address instead of a physical interface address as the
source IP address, because if the physical interface is down, the
response packets from the server cannot reach the device.
Set the RADIUS server response timeout.
