Table 40-37 Set a real-time accounting interval
Operation Command
Set a real-time accounting interval timer realtime-accounting minutes
Restore the default real-time accounting
interval undo timer realtime-accounting
The interval is in minutes and must be a multiple of 3.
The setting of real-time accounting interval somewhat depends on the performance of
the NAS 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). The following table lists the numbers of
users and the recommended intervals.
Table 40-38 Numbers of users and the recommended intervals
Number of users Real-time accounting interval (in minutes)
1 to 99 3
100 to 499 6
500 to 999 12
ƒ1000 ƒ15
The real-time accounting interval defaults to 12 minutes.
40.5 Displaying and Debugging AAA and RADIUS Protocol
After the above configuration, execute display command in any view to display the
running of the AAA and RADIUS/TACACS+ configuration, and to verify the effect of the
configuration. Execute reset command in user view to reset AAA and
RADIUS/TACACS+ statistics, etc. Execute debugging command in user view to
debug AAA and RADIUS/TACACS+.
