All check box, DATA VLAN Tag Stripping can be enabled or disabled
independent of enabling VLAN support on the PC Port.
If the DATA VLAN Tag Stripping is disabled, the packet is sent to the PC Port
unmodified. If the DATA VLAN Tag Stripping is enabled, the 802.1Q header
if one exists, is removed from the packet before the packet is forwarded
to the PC port.

DATA (PC Port) VLAN packet handling
— PC Port (Ingress direction)
— PC Port (Egress direction)
DATA (PC Port) VLAN Tag Stripping
DATA VLAN disabled—all traffic received on the PC port is switched
based on MAC address. The packets are not modified in any way.
DATA VLAN enabled—all untagged packets received on the PC port
have the 802.1Q header appended and the VLAN ID is set to the value
that was manually configured in the Data VLAN field. Any packet arriving
on the PC port that is already tagged is dropped.
DATA VLAN disabled—all traffic received on the PC port has the 802.1Q
header appended and the VLAN ID is set to the value which was
manually configured in the DATA VLAN field. Any packet arriving on the
PC port which is already tagged is dropped.
DATA VLAN enabled—all traffic is forwarded to the PC port based on
a review of the MAC address and the 802.1Q value that was manually
configured in the DATA VLAN field. Traffic is forwarded out the PC port
only if the packets contain the DATA VLAN tag. Untagged traffic and
traffic without the DATA VLAN tag is dropped.
