Description:
Tag-based VLAN is required when multiple networks have to communicate through a single physical interface, such as a switch port. Each network is assigned its own individual VLAN ID. The VLAN IDs are used to uniquely identify the communication.
Tagging modes are used to control the communication of inbound and outbound packets. There are three different VLAN tagging modes. Access, Trunk and Hybrid.
This article describes how the various VLAN tagging modes work.
Access (never):
This tagging mode is used when connecting a network device that cannot process VLAN IDs itself (such as a notebook). Info: For the sake of simplicity, the fact that an increasing number of network cards and even Windows offer partial support of VLAN is not considered in this document. The access port must have been given the appropriate port VLAN ID (PVID). This controls which network a device may communicate with.
