TCP iperf3 Testing
iperf.airstreamcomm.net runs an iperf3 server on the default port (5201)
ex: iperf3 -c iperf.airstreamcomm.net
Reverse Test
The default command runs a test where the client sends traffic to the server. To send traffic in the reverse direction use the -R flag
ex: iperf3 -c iperf.airstreamcomm.net -R
Alternate ports
The iperf3 software can only run a single test at a time. Because of this iperf.airstream.net runs multiple iperf3 servers on different ports.
You can run tests on different ports using the -p flag. Servers are running on ports 5201 through 5205.
ex: iperf3 -c iperf.airstreamcomm.net -p 5202 ex: iperf3 -c iperf.airstreamcomm.net -p 5203 ex: iperf3 -c iperf.airstreamcomm.net -p 5204 ex: iperf3 -c iperf.airstreamcomm.net -p 5205
IPv4/IPv6 Test
The iperf3 software will automatically select between IPv4 and IPv6. To force the client to use one or the other you can use the -4 or -6 flags.
ex: iperf3 -c iperf.airstreamcomm.net -4 ex: iperf3 -c iperf.airstreamcomm.net -6
