ONFIGURATION
while, it will consider that there is device failure and stop accounting. It is
necessary to disconnect the user at the NAS end and on the RADIUS server
synchronously when some unpredictable failure occurs. The Switch allows you to
set the maximum number of times of a real-time accounting request failing to be
responded to. NAS will disconnect the user if it has not received a real-time
accounting response from the RADIUS server for the specified number of times.
You can use the following command to set the maximum number of times of a
real-time accounting request failing to be responded to.
Perform the following configurations in RADIUS Scheme View.

Responded
Operation

connection will timeout in T and the real-time accounting interval of NAS is t, then
the integer part of the result from dividing T by t is the value of
when applied, it is suggested that T should be a number that can be divided
exactly by t.
By default, the real-time accounting request can fail to be responded to no more
than 5 times.
Enabling/Disabling the Stopping Accounting Request Buffer
Because the stopping accounting request concerns the account balance and will
affect the amount of charge, which is very important for both the subscribers and
the ISP, NAS shall make its best effort to send the message to the RADIUS
accounting server. If the message from the Switch to the RADIUS accounting
server has not been responded to, the Switch will save it in the local buffer and
retransmit it until the server responds or discards the messages after transmitting
for the specified number of times. The following command can be used for setting
to save the message or not.
Perform the following configurations in RADIUS Scheme View.
Table 317 Enabling/Disabling the Stopping Accounting Request Buffer
Operation
Enable stopping accounting request buffer stop-accounting-buffer enable
Disable stopping accounting request buffer undo stop-accounting-buffer enable
By default, the stopping accounting request will be saved in the buffer.
Setting the Maximum Retransmitting Times of Stopping Accounting
Request
Use this command to set the maximum number of retransmission times that the
Switch will attempt to retransmit the saved message from its local buffer.
Perform the following configurations in RADIUS Scheme View.
