Item Description
Server Type
Select the type of the RADIUS servers supported by the device:
•
Standard —Standard RADIUS servers. The RADIUS client and RADIUS
server communicate by using the standard RADIUS protocol and packet
format defined in RFC 2138/2139 or later.
•
Extended —Extended RADIUS servers, usually running on IMC. The
RADIUS client and the RADIUS server communicate by using the
proprietary RADIUS protocol and packet format.
Authentication Key
Confirm Authentication Key
Set the shared key for RADIUS authentication packets. The shared key and
the confirm key must match.
Accounting Key
Confirm Accounting Key
Set the shared key for RADIUS accounting packets. The shared key and the
confirm key must match.
NAS-IP
Specify the source IP address for the device to use in RADIUS packets to be
sent to the RADIUS server.
HP recommends using a loopback interface address instead of a physical
interface address as the source IP address. If the physical interface is down,
the response packets from the server cannot reach the device.
Timeout Interval Set the RADIUS server response timeout time.
Timeout Retransmission Times
Set the maximum number of transmitting attempts.
IMPORTANT:
The server response timeout time multiplied by the maximum number of
RADIUS packet transmission attempts must not exceed 75.
Realtime-Accounting Interval
Set the interval for sending real-time accounting information. The interval
must be a multiple of three.
To implement real-time accounting, the device must periodically send
real-time accounting packets to the accounting server for online users.
Different real-time accounting intervals impose different performance
requirements on the NAS and the RADIUS server. A shorter interval helps
achieve higher accounting precision but requires higher performance. Use a
longer interval when a large number of users (1000 or more) exist. For more
information about the recommended real-time accounting intervals, see
" Configuration guidelines ."
Realtime-Accounting Packet
Retransmission Times Set the maximum number of attempts for sending a real-time accounting
request.
Stop-Accounting Buffer
Enable or disable buffering of stop-accounting requests for which no
responses are received.
Stop-Accounting Packet
Retransmission Times Set the maximum number of transmission attempts if no response is received
for the stop-accounting packet.
Quiet Interval
Set the time the device keeps an unreachable RADIUS server in blocked
state.
