AAA and RADIUS Protocol Configuration 217
Perform the following configurations in RADIUS Scheme View.
Tab le 235 Setting the Response Timeout Timer of the RADIUS Server
By default, timeout timer of RADIUS server is 3 seconds.
Setting a Real-time Accounting Interval
To implement real-time accounting, it is necessary to set a real-time accounting
interval. After the attribute is set, NAS will transmit the accounting information of
online users to the RADIUS server regularly.
You can use the following command to set a real-time accounting interval.
Perform the following configurations in RADIUS Scheme View.
Tab le 236 Setting a Real-time Accounting Interval
minute specifies the real-time accounting interval in minutes. The value should be
a multiple of 3.
The value of minute is related to the performance of NAS and RADIUS server. The
smaller the value, the higher the performances of NAS and RADIUS that are
required. When there are a large amount of users (more than 1000, inclusive),
3Com suggests a larger value. The following table recommends the ratio of
minute value to the number of users.
Tab le 237 Recommended Ratio of Minute to Number of Users
By default, minute is set to 12 minutes.
Configure the RADIUS Server Response Timer
If the NAS receives no response from the RADIUS server after sending a RADIUS
request (authentication/authorization or accounting request) for a period of time,
the NAS resends the request, thus ensuring the user can obtain the RADIUS
service. You can specify this period by setting the RADIUS server response timeout
timer, taking into consideration the network condition and the desired system
performance.
Perform the following configurations in RADIUS Scheme View.
Operation Command
Set response timeout timer of RADIUS server timer second
Restore the response timeout timer of RADIUS server to default value undo timer
Operation Command
Set a real-time accounting interval timer realtime-accounting minute
Restore the default value of the interval undo timer realtime-accounting
Number of users Real-time accounting interval (minute)
1 to 99 3
100 to 499 6
500 to 999 12
1000 15
