The Iperf server communication port can be changed with the -p argument. It must be configured on the client and the server with the same value, default is TCP port 5001. The -t argument specifies the test duration time in seconds, default is 10 secs. The -i argument indicates the interval in seconds between periodic bandwidth reports. Client side: Jul 27, 2018 · To run Iperf in server mode, I will type the command “iperf3.exe -s from the Iperf directory. See image below: Running Iperf in client mode.
