What is the result of dynamic VLAN tagging on a switch port?

Dynamic VLAN tagging on a switch port allows the switch to automatically associate VLANs based on the traffic it receives. This means that instead of manually configuring each port to be assigned to a specific VLAN, the switch can identify the appropriate VLAN based on various parameters, such as the source address of incoming traffic. This feature is particularly beneficial in environments where devices move frequently between different VLANs, as it helps streamline network management and reduces administration overhead.

By using protocols such as VLAN Trunking Protocol (VTP) or through mechanisms like GVRP (GARP VLAN Registration Protocol), the switch is able to facilitate dynamic VLAN assignments. This enables the network to adapt to changing conditions automatically, promoting efficiency and scalability within the network infrastructure.
