252 CHAPTER 26: AAA AND RADIUS/HWTACACS PROTOCOL CONFIGURATION
You can use the following command to set the maximum times of real-time
accounting request failing to be responded.
Perform the following configuration in RADIUS scheme view.
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 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 request to RADIUS accounting
server. Accordingly, if the request from 3Com Series Switches to RADIUS
accounting server has not been responded, switch shall save it in the local buffer
and retransmit it until the server responds or discards the messages after
transmitting for specified times. You can use the following command to set
whether or not to save the stopping accounting requests.
Perform the following configuration in RADIUS scheme view.
By default, the stopping accounting request will be saved in the buffer.

Request
Because the stopping accounting request concerns 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 RADIUS accounting
server. Accordingly, if the request from 3Com Series Switch to RADIUS accounting
server has not been responded, switch shall save it in the local buffer and
retransmit it until the server responds or discards the messages after transmitting
for specified times. Use the following command to set the maximum
retransmission times.
Perform the following configuration in RADIUS scheme view.
