two machines two different nics

Hi, what would the commands be if I want to run iperf between the two PCs via their NIC2 interfaces? Thanks

PC1
NIC1 - 192.168.1.1
NIC2 - 12.12.12.1

PC2
NIC1 - 192.168.1.2
NIC2 - 12.12.12.2

If you want PC2 to be the server, then on PC2 do iperf3 --server.

On PC1 (which will be the client) do iperf3 --client 12.12.12.2 The argument to the --client option is the IP address of the server interface to connect to. Assuming you have NIC2 interfaces wired together directly or you have them on a common subnet, this should run all the test traffic over the NIC2 interfaces.
