Setting the Timers of the
RADIUS Server
Setting the Response Timeout Timer of the RADIUS Server
After RADIUS (authentication/authorization or accounting) request packet has been
transmitted for a period of time, if NAS has not received the response from the
RADIUS server, it has to retransmit the request to guarantee RADIUS service for the
user.
You can use the following command to set response timeout timer of RADIUS server.
Perform the following configurations in RADIUS Scheme View.
Table 466 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.
Table 467 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. Table 468 recommends the ratio of
minute value to the number of
users.
Table 468 Recommended Ratio of Minute to Number of Users
By default, minute is set to 12 minutes.
