RADIUS Protocol Configuration Commands 295
Description
Use the timer realtime-accounting command to configure a real-time
accounting interval.
Use the undo timer realtime-accounting command to restore the default
interval.
The setting of real-time accounting interval is indispensable to real-time
accounting. After an interval value is set, the NAS transmits the accounting
information of online users to the RADIUS accounting server at intervals of this
value.
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.
By default, the interval of realtime accounting is 12 minutes.
Related command: retry realtime-accounting and radius scheme.
Example
# Set the real-time accounting interval in the RADIUS scheme "3com" to 51
minutes.
