3.1.2.2.2 Tag-Based VLAN
The second type of VLAN is the tag-based VLAN. VLAN membership in a tagged
VLAN is determined by information within the frames that are received on a port. This
differs from a port-based VLAN, where the port VIDs assigned to the ports determine
VLAN membership
When the device receives a frame with a VLAN tag, referred to as a tagged frame, the
device forwards the frame only to those ports that share the same VID.
