    I219-LM: Wireshark can not see VLAN tag header and Ostinato can not send VLAN tagged frames




      I have Wireshark (v2.4.1) and Ostinato Network Traffic Generator (v0.6) installed on my laptop (Window 10 Pro version 1703, OS Build 15063.608) with Intel Ethernet Connection I219-LM. However I am not able to either receive or send VLAN tagged packets. Untagged packets are fine in both transmit and receiving directions.


      I did not have such issue with my old laptop (Windows 7 Enterprise SP1, Intel 82579LM), I was able to use Wireshark to capture VLAN tagged frames and see the VLAN tag in the captured results, and I was able to send VLAN tagged frames using Ostinato or Linux tcpreplay.


      I found a thread https://communities.intel.com/thread/22204, and added "MonitorMode"  registry key using regedit.


      In my case

      - Setting the MonitorMode value to 1 did not help. Wireshark still could not receive tagged frames. Ostinato could not transmit tagged frames.

      - Setting the MonitorMode value to 2 helped a bit. Wireshark  could receive tagged frames, however the VLAN tag was stripped in the capture result. Ostinato could not transmit tagged frames.


      My goals are 1) to see VLAN tags in the Wireshark capture result; 2) to use Ostinato or tcpreplay to send VLAN tagged frames.


      System information -

      System Model: Dell Latitude E7470

      OS:           Windows 10 Pro 10.0.15063 N/A Build 15063

      Driver:       Intel(R) Ethernet Connection I219-LM. Driver version:

      I also installed the Intel® Network Adapter Driver from https://downloadcenter.intel.com/download/25016/Intel-Network-Adapter-Driver-for-Windows-10.


      Any advice/suggestions are appreciated.
