      <title>vmxnet3 NIC removes VLAN tags in Windows 7 x64 VM</title>
      <link>https://communities.vmware.com/t5/ESXi-Discussions/vmxnet3-NIC-removes-VLAN-tags-in-Windows-7-x64-VM/m-p/451197#M37252</link>
      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi All,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I have a distributed vSwitch with a port group that has a range of VLANs enabled. An Ubuntu 14 x64 VM and a Windows 7 x64 VM both have a pair of vmxnet3 NICs each and their 2nd NIC is connected to that port group for traffic monitoring purposes (I have Wireshark running on both VMs). I can see VLAN tags on traffic captured by the former one but not the latter one. How do I fix the latter one? I assume my VGT mode is fine and the problem is within guest (e.g. vmxnet3 driver?), else I wouldn't be seeing VLAN tags on Ubuntu VM either.&lt;/P&gt;&lt;P&gt;The port group is set to Promiscuous mode, VLAN&amp;nbsp; and VLAN Trunking 0-4094 (it won't let me enter 4095 there - I suppose 4095 is only applicable to standard vSwitch):&lt;/P&gt;&lt;P&gt;&lt;A href="https://s7.postimg.org/3zyx57kej/image.png" style="font-size: 10pt;" title="https://s7.postimg.org/3zyx57kej/image.png"&gt;https://s7.postimg.org/3zyx57kej/image.png&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;A href="https://s28.postimg.org/qhx6xeh31/image.png" style="font-size: 10pt;" title="https://s28.postimg.org/qhx6xeh31/image.png"&gt;https://s28.postimg.org/qhx6xeh31/image.png&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Already tried using E1000 NIC instead of vmxnet3 and &lt;SPAN style="font-size: 13.3333px;"&gt;that doesn't help&lt;/SPAN&gt; even after adding "MonitorMode=1" or "MonitorModeEnabled=1" into Windows Registry as advised in an Intel document (those settings do help in case of &lt;EM&gt;physical&lt;/EM&gt; Intel NICs). Meanwhile several sources report E1000 NIC preserving VLAN tags with Linux.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;A KB article on how to make it work in Windows with all of the most commonly used NIC types would be ideal.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Many thanks in anticipation!&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
