Parameter
minutes: Real-time accounting interval, which is a multiple of 3 in the range 3 to 60
minutes. By default, the real-time accounting interval is 12 minutes.
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.
Note that:
z Real-time accounting interval is necessary for real-time accounting. After an
interval value is set, the switch transmits the accounting information of online
users to the TACACS accounting server at intervals of this value.
z The setting of real-time accounting interval depends somewhat on the
performance of the switch and the TACACS 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).
Table
1-6 recommends the real-time accounting intervals for different numbers of users.
