3. Enter the IP address of the remote device that you want to test, and then click Measure Throughput.
Figure 89 Iperf
The specified IP address must be running Iperf in Server mode. If the remote modem does not have
the Iperf server running, you will get the error message “perf error, check connectivity to server.”
Ensure that it has been enabled and reset the module. Each time you click Measure Throughput, a
10-second TCP throughput test is performed.
You will see the message “Performing Iperf Test,” and if you look at the modules you will see the TX/
Link and RX LEDs flashing quickly as it performs the test. After about 10 seconds, a graph appears
showing the actual throughput over the 10-second period and a calculated average.
The graph below shows the data throughput range between 8 and 14.5 Mbits per second with an
overall average of 10.9 Mbits per second. It is recommended to perform this throughput test a number
of times to get a better sample of the overall throughput.
