You can make a donation via this site: IEEE : Tagging and trunking 101 Today my topic is IEEE standard: tagging and trunking basics. I talk about many terminologies such as VLAN tag, tagging, encapsulation, trunk, trunking, trunk port, and an access port. I will use an example to show what they are and how they work. The IEEE , often referred to as Dot1q, is the networking standard that supports VLANs on the Ethernet network. The standard defines a method of tagging traffic between two switches to tell which traffic belongs to which VLAN. Keep in mind, there are many implementations of IEEE 8021.q standard, but we tend to talk more about using Cisco switches.
