    NIC detected, no flow/traffic 6.5.0 Update 1 (Build 7388607)

    mohsh86 Novice

      I have an AMD Ryzen 1800x on Asus Prime B350 Motherboard.


      I initially had issues with the onboard Realtek Gb LAN, i tried the community vib, searched forums, eventually found a workaround of shutting down the esxi, cut off the power from the MB, then powering it back again.


      Since this isn't practical, i bought an Intel E1G42ET  (supposedly supported) and chucked in on the 2nd PCIe x16 slot (the rest of the slot empty of course). esxi detect the two nics (driver igb), but:


      1. There is no flow from the NIC/s

      2. NIC will show Up - 1000 Full when connected, but when disconnected, will still show Up with speed of 65535 and Full duplex?!


      any idea where i should start looking ?





      To confirm the issue isn't hardware, i booted a live Ubuntu and tried the 3 nics, all works like a charm!



      Driver currently used by ESXi is "igb"

         Module: igb

      however, listing VIBs containing "igb" would yeild:

      net-igb                      VMW      VMwareCertified     2018-02-05


      is the system using the right driver ?

          What do you mean saying 'there is no flow'?

          How do you check?

            I check via Wireshark, hooking a laptop directly to the NIC and sniffing through Wireshark, no packets.

              can you show your virtual switch configuration?

              As well can you show management network settings (which vmnic is used) from DCUI?

                management network and VM network are on vSwitch 0 that is hooked up to the built-in LAN (Realtek - vmnic0) which is working fine, i am trying to get the Intel 82576 dual NIC to work.


                adding vmnic1/2 as uplinks to the management network (setting as stand-by, pulling main cable ) does not get them to initiate traffic

                  So you have virtual machine portgroup on vSwitch1 and some VMs connected to it. Right? Can VMs in the same port group ping each other\or connect with any other protocol (RDP\SSH\etc..)?

                  Do you have VLAN id assigned to this port group?


                  Can you show some outputs as well:

                  esxcli network nic list


                  esxcli networ nic get -n vmic# (where# is the number of affected network adapter)


                  as well can you attach vmkernel.log from the host?

                    I was able to ping/rdp between guests on the same Port Group / vSwitch, i've attached all files in /var/log as well as dmesg output

                      Another thing worth mentioning:


                      1. i ran wireshark on the Win10 guest, when ever i change a setting on the corresponding vSwitch the following packet is received.




                      2.  I've just checked the switch, looks like port 9 (where vmnic1 is connected) is sending bytes (bytes received on switch statistics), however, connecting the NIC directly to my laptop with wireshark on yields nothing.

                        Can you try to update the driver https://my.vmware.com/group/vmware/details?downloadGroup=DT-ESXI55-INTEL-IGB-525&productId=353  ?


                        As well can you describe a bit more your test when you tried to check network connectivity? I'd like to see ifconfig/ipconfig from both source and destination and information about VLAN ID assigned to VM port group?

                          You can capture network traffic inside port group only when you configure Promiscuous mode.


                          Can you also say what is a NIC Teaming policy you use on vSwitch1\port group?

                            I've enabled Promiscuous mode on vSwitch1, nothing is coming from the outside.


                            Teaming policy is inherited from vSwitch1
