User's Manual
Defines VLAN tagging per Ethernet Device.

[0] Untagged = (Default of pre-configured Ethernet Device)
The Ethernet Device accepts untagged packets as well as
packets with the same VLAN ID as configured for the
Ethernet Device. Incoming untagged packets are assigned
the VLAN ID of the Ethernet Device. The Ethernet Device
sends these VLAN packets untagged (i.e., removes the VLAN
ID).

[1] Tagged = (Default for new Ethernet Devices) The Ethernet
Device accepts packets that have the same VLAN ID as
configured for the Ethernet Device and sends packets with
this VLAN ID. For all Ethernet Devices that are associated
with the same Ethernet Group ('Underlying Interface') and set
to Tagged, incoming untagged packets received on this
Ethernet Group are discarded.
Note: Only one Ethernet Device can be configured as Untagged
per associated Ethernet Group (port group). In other words, if
multiple Ethernet Devices are associated with the same Ethernet
Group, only one of these Ethernet Devices can be set to
Untagged; all the others must be set to Tagged.
