Port VLAN Identifier (PVID) is a classification mechanism that associates a port with a specific VLAN
and is used to make forwarding decisions for untagged packets received by the port. For example, if
port #2 is assigned a PVID of 3, then all untagged packets received on port #2 will be assigned to VLAN
3. This number is generally the same as the VID# number assigned to the port in the 802.1Q Static
VLAN Settings screen above.

assigned to the port. If the two are different, the port filters (drops) the packet.
