By default, RADIUS request packet will be retransmitted up to three times.
40.3.6 Enabling the Selection Of Radius Accounting Option
If no RADIUS server is available or if RADIUS accounting server fails when the
accounting optional is configured, the user can still use the network resource,
otherwise, the user will be disconnected.
Perform the following configuration in RADIUS scheme view.
Table 40-15 Enable the selection of RADIUS accounting option
Operation Command
Enable the selection of RADIUS accounting option accounting optional
Disable the selection of RADIUS accounting option undo accounting optional
By default, selection of RADIUS accounting option is disabled.
40.3.7 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 configuration in RADIUS scheme view.
Table 40-16 Set a real-time accounting interval
Operation Command
Set a real-time accounting interval timer realtime-accounting minute
Restore the default value of the interval undo timer realtime-accounting
minute specifies the real-time accounting interval in minutes. The value shall be a
multiple of 3.
The value of minute is related to the performance of NAS and RADIUS server. The
smaller the value is, the higher the performances of NAS and RADIUS are required.
When there are a large amount of users (more than 1000, inclusive), we suggest a
larger value. The following table recommends the ratio of minute value to the number of
users.
