5.9.2 Port VID
The interface sets 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 you want to
participate in the VLAN but that don't support tagging. Only one untagged
VLAN is allowed per port.
