    iperf3: error - unable to start listener for connections: Cannot assign requested address

      Hi folks,

       

      in our lab we've a 6.7U3 vsan cluster and we want to make some tests with traffic shaping via distributed switch on the vmotion network.

      However, we're not able to get it working on the vmotion vmkX. It's running on the vsan adapter and on the mgmt-adapter though.

       

      error on vmotion adapter

      # iperf version

      iperf 3.1.6

       

       

      #turning of the firewall

      esxcli network firewall set --enabled false

       

      # running the server side of iperf

       

      /usr/lib/vmware/vsan/bin/iperf3.copy -s -B X.Y.1.18

      iperf3: error - unable to start listener for connections: Cannot assign requested address

      working example from the vsan adapter

      /usr/lib/vmware/vsan/bin/iperf3.copy -s -B X.Y.2.18
