Access ports handle traffic for one untagged VLAN, while trunk ports route traffic to and from multiple VLANs using VLAN tags.
A trunk port can transmit data from multiple VLANs through the same physical interface (or network port). This requires each additional VLAN using the physical interface to use packet tagging.
Access ports provide direct access to a specific VLAN and remove any VLAN tagging enabling devices that don’t support (or are not configured for) VLANs to access the network segment.
Whether the port type is set to Access or Trunk, which VLANs are accessible on that port are selectable in the interface.
