40.3.8 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. The Switch 8800 supports setting 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 configuration in RADIUS scheme view.

responded

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.
