|
|
- Run iperf3 as a server:
|
|
|
|
|
|
2025-04-03 20:36:56 -06:00
|
|
|
`iperf3 {{[-s|--server]}}`
|
2025-03-14 21:59:59 -06:00
|
|
|
|
|
|
|
|
- Run an iperf3 server on a specific port:
|
|
|
|
|
|
2025-04-03 20:36:56 -06:00
|
|
|
`iperf3 {{[-s|--server]}} {{[-p|--port]}} {{port}}`
|
2025-03-14 21:59:59 -06:00
|
|
|
|
|
|
|
|
- Start bandwidth test:
|
|
|
|
|
|
2025-04-03 20:36:56 -06:00
|
|
|
`iperf3 {{[-c|--client]}} {{server}}`
|
2025-03-14 21:59:59 -06:00
|
|
|
|
|
|
|
|
- Run iperf3 in multiple parallel streams:
|
|
|
|
|
|
2025-04-03 20:36:56 -06:00
|
|
|
`iperf3 {{[-c|--client]}} {{server}} {{[-P|--parallel]}} {{streams}}`
|
2025-03-14 21:59:59 -06:00
|
|
|
|
|
|
|
|
- Reverse direction of the test. Server sends data to the client:
|
|
|
|
|
|
2025-04-03 20:36:56 -06:00
|
|
|
`iperf3 {{[-c|--client]}} {{server}} {{[-R|--reverse]}}`
|
