behavior of the PC port is summarized in the following table.
Table 18
PC Port (incoming traffic from PC)
Data VLAN
No
4095 (Note that the value 4095 is not a valid
VLAN ID. This is intentional to ensure a proper
VLAN ID is entered.)
Table 19
PC Port (outgoing)
Data VLAN
No
4095 (Note that the value 4095 is not a valid
VLAN ID. This is intentional to ensure a proper
VLAN ID is entered.)

PC-Port Untag all

Configure PC-Port Untag-All, which configures PC-Port VLAN Tag Stripping.
When enabled, all outgoing traffic to the PC has the VLAN tag removed.
When disabled, packets are sent to the PC as is if Data VLAN is set to
No or if Data VLAN is enabled and the VLAN tag matched. Packets with
different VLAN ID are discarded.

Result
All traffic received on the PC port is forwarded
based on the MAC address. The packets are not
modified in any way.
All untagged packets received from the PC have
an 802.1q header appended and the VLAN ID
is set to the value that is manually provisioned
in this field. Any packet arriving on the PC port
that is already tagged with matching VLAN ID is
forwarded as is. Packets tagged with different
VLAN IDs are dropped.
Result
All traffic received on the network port and
telephony port is forwarded to the PC port based
on MAC address only. The packets are not
modified in any way.
Traffic is forwarded to the PC port based on a
review of the MAC address of the packet, as well
as the value configured in the Data VLAN field.
Traffic is forwarded out the PC port (to the PC)
only if the packets contain the Data VLAN tag.
Untagged traffic and traffic with a VLAN tag other
than the Data VLAN are dropped.
