iperf3

Traffic generator for testing network bandwidth. More information: https://iperf.fr/iperf-doc.php.

• Run iperf3 as a server:

iperf3 {{[-s|--server]}}

• Run an iperf3 server on a specific port:

iperf3 {{[-s|--server]}} {{[-p|--port]}} {{port}}

• Start bandwidth test:

iperf3 {{[-c|--client]}} {{server_ip}}

• Run iperf3 in multiple parallel streams:

iperf3 {{[-c|--client]}} {{server_ip}} {{[-P|--parallel]}} {{streams}}

• Run the test in reverse direction (server sends data to client):

iperf3 {{[-c|--client]}} {{server_ip}} {{[-R|--reverse]}}

• Set the duration of the test:

iperf3 {{[-c|--client]}} {{server_ip}} {{[-t|--time]}} {{seconds}}
