What Does Trunk Port Mean?
A trunk port is a specific type of port on a network switch that allows data to flow across a network node for multiple virtual local area networks or VLANs. Think of the trunk port as a “bundle” of individual branches or capillaries in a telecom network connection.
Techopedia Explains Trunk Port
The “trunk port” relies on the basic idea of “trunking” — that a single point-to-point connection can handle two different kinds of traffic. In this case, that means handling traffic for more than one VLAN.
