3.1.2.2.3 Tag-Based VLAN
The second type of VLAN is the tag-based VLAN. VLAN membership in a tagged
VLAN is determined by VLAN information within the packet 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.
