VLAN tagging is a method of assigning devices in a network to virtual LANs (VLANs). A VLAN tag, also called an 802.1Q tag, is a number that‘s added to the header of an Ethernet frame. This tag identifies which VLAN the frame belongs to and defines the service level associated with that VLAN. By tagging frames, switches can forward traffic to the correct VLAN while also providing some degree of security by separating traffic from other networks. VLAN tagging is a key part of modern network design, providing segmentation and access control for applications, workgroups, and departments.
