1.3.12 Setting the Maximum Times of Real-time Accounting Request Failing
to be Responded
RADIUS server usually checks if a user is online with timeout timer. If the RADIUS
server has not received the real-time accounting packet from NAS for long, it will
consider that there is device failure and stop accounting. Accordingly, it is necessary to
disconnect the user at NAS end and on RADIUS server synchronously when some
unpredictable failure exists. H3C Series Switches support to set maximum times of
real-time accounting request failing to be responded. NAS will disconnect the user if it
has not received real-time accounting response from RADIUS server for some
specified times.
You can use the following command to set the maximum times of real-time accounting
request failing to be responded.
Perform the following operations in RADIUS scheme view to configure the maximum
times of real-time accounting request failing to be responded
Set maximum times of real-time
accounting request failing to be responded
Restore the maximum times to the default
value
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.
1.3.13 Enabling/Disabling Stop-Accounting Request Buffer
Because the stop-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 H3C Series Switches to RADIUS accounting server has not been
responded, switch shall save it in the local buffer and retransmit it until the server
