response, NAS considers the communication with the current RADIUS server
disconnected and will transmit the request packet to other RADIUS servers.
Perform the following configurations in RADIUS server group view.
By default, RADIUS request packet will be retransmitted up to three times.
Enabling the Selection of the 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 configurations in RADIUS server group view.
The user configured with accounting optional command in RADIUS scheme longer
sends a real-time accounting update packet or offline accounting packet.
The accounting optional command in a RADIUS server group view is only
effective on the accounting that uses this RADIUS server group.
By default, selection of RADIUS accounting option is disabled.
Setting a Real-time Accounting Interval
To implement this feature, 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.
Perform the following configurations in RADIUS server group view.
The minute variable specifies the real-time accounting interval in minutes. The
value must 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 have to be.
When there are a large amount of users (more than 1000, inclusive), we suggest a
