Configuring the RADIUS Protocol 45
information of online users to the RADIUS accounting server at intervals of this
value.
Perform the following configuration in RADIUS view.
In the command, minutes represents the interval for realtime accounting and it
must be a multiple of three.
The setting of real-time accounting interval somewhat depends on the
performance of the NAS and the RADIUS server: a shorter interval requires higher
device performance. You are therefore recommended to adopt a longer interval
when there are a large number of users (more than 1000, inclusive). The following
table recommends the ratio of minutes to the number of users.
The realtime accounting interval defaults to 12 minutes.
