You can use the following command to set a real-time accounting interval.
Perform the following configurations in RADIUS Scheme View.
Table 329 Setting a Real-time Accounting Interval
Operation
Set a real-time accounting interval

specifies the real-time accounting interval in minutes. The value should be
minute
a multiple of 3.
The value of is related to the performance of NAS and RADIUS server. The
minute
smaller the value, the higher the performances of NAS and RADIUS that are
required. When there are a large amount of users (more than 1000, inclusive),
3Com suggests a larger value. The following table recommends the ratio of
value to the number of users.

Configure the RADIUS Server Response Timer
If the NAS receives no response from the RADIUS server after sending a RADIUS
request (authentication/authorization or accounting request) for a period of time,
the NAS resends the request, thus ensuring the user can obtain the RADIUS
service. You can specify this period by setting the RADIUS server response timeout
timer, taking into consideration the network condition and the desired system
performance.
Perform the following configurations in RADIUS Scheme View.
