Have you enabled LACP on the servers? there are different modes of LAG, on windows servers there are Static, switch independent and LACP

The configuration of the 2 servers ,.

Now i have the ping between the 2 servers and I can test iperf3 . I just want to understand why when I put the two interfaces into the active and passive mode, I see that the two cables pass the network, I thought that the passive mode in the 2 interface is just like a stand by in case the first cable is down it doesn't send any packets.

Is my configuration on the switch correct ? Am I missing any command?
