Section 5.2.1.1
Tagged vs. Untagged Frames
VLAN tags identify frames as part of a VLAN network. When a switch receives a frame with a VLAN (or 802.1Q)
tag, the VLAN identifier (VID) is extracted and the frame is forwarded to other ports on the same VLAN.
When a frame does not contain a VLAN tag, or contains an 802.1p (prioritization) tag that only has prioritization
information and a VID of 0, it is considered an untagged frame.
Section 5.2.1.2
Native VLAN
Each port is assigned a native VLAN number, the Port VLAN ID (PVID). When an untagged frame ingresses a
port, it is associated with the port's native VLAN.
