Figure 9-1: LAN Throughput Configuration

Data transmission occurs when the amount of data to report meets or exceeds
the data size specified in the Threshold field, but only if the Minimum Report
Interval time has elapsed. If the threshold hold has not been reached, it will be
sent when the Maximum Report Interval elapses.

For more information on these fields see

LAN Throughput Settings

Note: It's recommended that the default interval and threshold values be used in order to
maintain the optimum frequency for sending out the LAN Throughput report.
