Configuring Virtual Guest VLAN tagging (VGT) mode on a vNetwork Distributed Switch (1010733)

  • 0 Ratings


This article describes the concept and configuration of Virtual Guest VLAN tagging (VGT) mode on ESX 4.x.


Note: For additional information on dvPortGroup configuration, see vNetwork Distributed PortGroup (dvPortGroup) configuration (1010593).
This is a new Virtual Network Adapter, also known as Advanced VMXNET. It is based on Enhanced VMXNET introduced in ESX 3.5, it provides these new features:
  • IEEE 802.1Q VLAN tagging
  • No more need for e1000 Driver inside of a virtual machine
  • VLAN tagging and tag removal offloading
  • Only one VLAN per NIC for Windows
  • TCP Segmentation Offloading for IPv4 and IPv6
  • TCP and UPD Checksum Offloading for IPv4 and IPv6
  • MSI (Messaged Signalled Interrupt) and MSI-X support (subject to guest kernel support)
  • Receive Side Scaling (supported in Windows Vista, 2008 and any other system using NDIS 6.x)
  • VMXNET 3 is the new “state of the art” Virtual Network Adapter.
To modify and add vNetwork Distributed Port Groups (dvPortGroup):
  1. In vCenter, click Home > Inventory > Networking.
  2. Right-click on dvPortGroup and choose Edit Settings.
  3. Under dvPortGroup > Policies > VLAN, these settings can be specifed:
    • VGT – VLAN Guest Tagging
    • VLAN Trunking – Physical equivalent to: VLAN in Trunk/Tagged mode
    • Standard vSwitch equivalent to: VLAN ID set to 4095 

      Distributed Switch Only specifies the range of VLANs to trunk, to improve security.
