Description
RADIUS server, the device considers the request a failure.
IMPORTANT:
The server response timeout time multiplied by the maximum number of
RADIUS packet transmission attempts must not exceed 75.
Set the interval for sending realtime accounting information. The interval
must be a multiple of 3.
To implement realtime accounting, the device must send realtime
accounting packets to the accounting server for online users periodically.
Different realtime 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 realtime accounting intervals,
see "Configuration guidelines."
Set the maximum number of attempts for sending a realtime accounting
request.
Specify the unit for data flows sent to the RADIUS server, which can be:
•
Byte.
•
Kilo-byte.
•
Mega-byte.
•
Giga-byte.
Specify the unit for data packets sent to the RADIUS server, which can be:
•
One-packet.
•
Kilo-packet.
•
Mega-packet.
•
Giga-packet.
Specify the IP address of the security policy server.
Specify the source IP address for the device to use in RADIUS packets
sent to the RADIUS server.
Hewlett Packard Enterprise recommends you to use 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.
Enable or disable buffering of stop-accounting requests for which no
responses are received.
Set the maximum number of stop-accounting attempts.
The maximum number of stop-accounting attempts, together with some
other parameters, controls how the NAS deals with stop-accounting
request packets.
Suppose that the RADIUS server response timeout period is three
seconds, the maximum number of transmission attempts is five, and the
maximum number of stop-accounting attempts is 20. For each
stop-accounting request, if the device receives no response within three
seconds, it retransmits the request. If it receives no responses after
retransmitting the request five times, it considers the stop-accounting
attempt a failure, buffers the request, and makes another stop-accounting
attempt. If 20 consecutive attempts fail, the device discards the request.
Enable or disable the accounting-on feature.
The accounting-on feature enables a device to send accounting-on
packets to RADIUS servers after it reboots, making the servers forcedly
log out users who logged in through the device before the reboot.
