3Com 7700 Configuration Manual page 203

How to calculate the value of retry-times? Suppose that RADIUS server 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 count. Therefore, when
applied, T is suggested the numbers which can be divided exactly by t.
By default, the real-time accounting request can fail to be responded no more
than 5 times.
Enabling/Disabling Stopping Accounting Request Buffer
Because the stopping accounting request concerns account balance and affects
the amount to charge a customer, NAS makes its best effort to send the message
to RADIUS accounting server. Accordingly, if the message from the Switch 7700 to
RADIUS accounting server has not been responded, the switch saves it in the local
buffer and retransmits until the server responds or discards the messages. The
following command can be used to enable the storage of the Stop Accounting
message. If stop-accounting buffer is enable, make sure you set the maximum
retransmission time.
Perform the following configurations in RADIUS server group view.
Table 26 Enable/Disable Stopping Accounting Request Buffer
Operation
Enable stopping accounting
request buffer
Disable stopping accounting
request buffer
By default, the stopping accounting request will be saved in the buffer.
Setting the Maximum Retransmitting Times of Stopping Accounting
Request
Because the stopping accounting request concerns account balance and will affect
the amount to charge a customer, which is very important for both the subscribers
and the ISP, NAS shall make its best effort to send the message to RADIUS
accounting server. Accordingly, if the message from the Switch 7700 to RADIUS
accounting server has not replied, the switch saves it in the local buffer and
retransmits it until the server responds or discards the messages. Use the
command to set the maximum retransmission times.
Perform the following configurations in RADIUS server group view.
Table 27 Set the Maximum Retransmitting Times of Stopping AccountingRequest
Operation

By default, the stopping accounting request can be retransmitted for up to 500
times.
