VLAN tagging is a method through which more than one VLAN is handled on a port. VLAN tagging is used to tell which packet belongs to which VLAN on the other side. To make recognition easier, a packet is tagged with a VLAN tag in the Ethernet frame. Independent logical systems can be ...
A VLAN access port is a networking port that is used to carry traffic for a single VLAN (Virtual Local Area Network) over a physical connection. Access ports are often used to connect devices such as computers, printers, and other end-user devices to a network, and are typically configured...

Trunk port(Tagged): A VLAN trunk port is a networking port that is used to carry traffic for multiple VLANs (Virtual Local Area Networks) over a single physical connection. Trunk ports are often used to connect switches, routers, and other networking devices in a network, and are typically...

IEEE 802.1Q adds a 4-byte VLAN tag to an Ethernet frame, enabling switches to identify the VLAN to which the received frame belongs. VLAN-tagged frame format defined in IEEE 802.1Q The VID field in a data frame identifies the VLAN to which the frame belongs (that is, the VLAN ID). ...
If the sub-interface receives double-tagged VLAN packets, it forwards only those packets with a specified outer VLAN tag. untag: This type of sub-interface accepts only packets that do not carry VLAN tags. qinq: This type of sub-interface accepts only packets with specified double VLAN tags....
Switches forward tagged frames toward their destinationmedia access control address, forwarding only to ports with which the VLAN is associated. Broadcast, unknown unicast and multicast traffic is forwarded to all ports in the VLAN.Trunklinks between switches know which VLANs span the switches, accept...
