Description
Set the maximum number of attempts for transmitting a RADIUS packet to a
single RADIUS server. If the device does not receive a response to its request
from the RADIUS server within the response timeout period, it retransmits the
RADIUS request. If the number of transmission attempts exceeds the limit but
the device still does not receive a response from the 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 real-time accounting information. The interval
must be a multiple of 3.
To implement real-time accounting, the device must send real-time
accounting packets to the accounting server for online users periodically.
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."
Set the maximum number of attempts for sending a real-time 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.
HP 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.
