vlan Membership Flag

Here are the definitions that I pulled from page 126 of the User Guide:

T          --  The interface is a member of a VLAN. All packets forwarded by the interface are tagged. The packets contain VLAN information.

U          --  The interface is a VLAN member. Packets forwarded by the interface are untagged.

F          --  The interface is denied membership to a VLAN.

Blank    --  The interface is not a VLAN member. Packets associated with the interface are not forwarded.
