Disabling vmkernel VLAN Tagging
When Virtual Local Area Networks (VLANs) are created within your ESX Server, the
vmkernel, by default, manages the VLAN processing of Ethernet frames. If you do not
want the vmkernel to manage VLAN processing, you can configure the vmkernel to
pass all Ethernet frames between guest operating systems and the outside network.
To change your VLAN processing settings:
1. From the Options tab, select Advanced Settings. The Advanced Settings page
appears and displays a list of configuration parameters.
2. Locate the parameter: Net.VlanTrunking.
3. Click the value for the parameter. The Modify VMkernel Parameter window
opens.
4. In the Value entry field, enter 1 (one) to enable the parameter or 0 (zero) to
disable the parameter.
5. Click OK to close the window and save the setting.
