z
To control the interval at which users are charged in real time, you can set the real-time accounting
interval. After the setting, the switch periodically sends online users' accounting information to
TACACS accounting server at the set interval.
z
The setting of the real-time accounting interval depends, to some degree, on the performance of
the switch and the TACACS server. The higher the performance of the switch and the TACACS
server is, the shorter the interval can be. It is recommended to set the interval as long as possible
when the number of users is relatively great (
≥ 1000). The following table lists the recommended
intervals for different numbers of users.
