IEEE The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames. The standard also contains provisions for a quality-of-service prioritization scheme commonly known as IEEE Portions of the network which are VLAN-aware i. The standard was developed by IEEE
Intro to Networking - Introduction to Virtual LANs (VLANs) and Tagging
The move from hubs shared networks to switched networks was a big improvement. Control over collisions, increased throughput, and the additional features offered by switches all provide ample incentive to upgrade infrastructure. But Layer 2 switched topologies are not without their difficulties. Extensive flat topologies can create congested broadcast domains and can involve compromises with security, redundancy, and load balancing. These issues can be mitigated through the use of virtual local area networks, or VLANs. This discussion will include trunking methods used for interconnecting devices on VLANs. With any single shared media LAN segment, transmissions propagate through the entire segment.
FortiSwitch ports process tagged and untagged Ethernet frames. Tagged frames include an additional header the Outgoing packets for the native VLAN are sent as untagged frames. At this point, all packets are now tagged with a valid VLAN. The packet is sent out from Port1 and Port3. Then it flows out all ports that will send Vlan Port 3.
The use of double-tagging (or VLAN stacking) to tunnel VLANs across Layer 2 networks is Mixing tagged and untagged packets on the same port. To allow a switch port to distinguish and identify traffic from different VLANs, put it in trunk.

Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up. From what the material I am reading says, a tagged port is used to allow a host to be seen from different VLANs. So for example if the port 1 is tagged on "vlan 1", and also tagged on "vlan 2", it can send level 2 packets to every host in both VLANs. If yes, what's the difference?
I need help in understanding VLAN's and how to separate voice and data traffic. Everything is working fine. I am the one that setup the entire network from scratch across multiple switches and devices. What I want to do is create a pipe for PC traffice and a pipe for phone traffic that goes from our workstation POE switches to our core switch.

- Почему же вся переписка Северной Дакоты оказалась в твоем компьютере. - Я ведь тебе уже говорил! - взмолился Хейл, не обращая внимания на вой сирены. - Я шпионил за Стратмором. Эти письма в моем компьютере скопированы с терминала Стратмора - это сообщения, которые КОМИНТ выкрал у Танкадо. - Чепуха.
