Port VID (PVID)
Set the Port VLAN ID that will be assigned to untagged traffic on a given port. For example, if port 10's default PVID is 100,
all untagged packets on port 10 will belong to VLAN 100. The default setting for all ports is VID 1.
This feature is useful for accommodating devices that one wants to participate in the VLAN but don't support tagging. Only
one untagged VLAN is allowed per port.

NVF-800S has two ingress filtering rule:
Ingress Filtering Rule 1: Forward only packets with VID matching this port's configured VID.
Ingress Filtering Rule 2: Drop Untagged Frame.
