Untagged port membership between two VLAN-aware devices with no
intervening VLAN-aware devices, should be to the same VLAN. In other words, the
PVID on the ports between the two devices must be the same if the ports are to
send and receive untagged packets to and from the VLAN. Otherwise, traffic might
leak from one VLAN to another.
Frames that are VLAN-tagged can pass through other network devices that are
VLAN-aware or VLAN-unaware. If a destination end node is VLAN-unaware, but is
to receive traffic from a VLAN, then the last VLAN-aware device (if there is one),
must send frames of the destination VLAN to the end node untagged.
To view VLAN membership:
Click VLAN Management > Port VLAN Membership.
Select an interface type (Port or LAG), and click Go.
The operational membership of the ports or LAGs is displayed:

member.

•
Mode—Displays the port VLAN mode that was selected on the Interface
