If tags must be preserved, the port mode must be set to trunk mode. If tags do not need to be preserved, the port mode must be set to access mode.
If the host will not be VLAN aware, set the vNIC to access mode.
The mode you configure (trunk or access) affects both vNICs and Ethernet ports that are members of the VLAN. Whichever configuration method you choose, use the GUI to create the VLAN. Refer to the Oracle Fabric Manager 5.0.2 Administration Guide.
