Highlight the Configure Port from [1 ] to [1 ] field and enter the range of port numbers you want to
configure. Next, highlight the PVID field and enter the PVID for the VLAN’s member ports you want to
configure.
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.

An Ingress Filter enables the port to compare the VID tag of an incoming packet with the PVID number
assigned to the port. If the two are different, the port filters (drops) the packet.
