access port
also: untagged port, edge port
A network port on a switch that carries traffic for a single VLAN, typically used for connecting end devices like computers or printers to the network.
An access port is a switch interface configured to belong to exactly one VLAN (Virtual Local Area Network). Unlike trunk ports that carry multiple VLANs, access ports strip VLAN tags from outgoing frames and add tags only to incoming frames destined for their assigned VLAN.
Access ports are the standard connection type for end devices such as workstations, printers, IP phones, and servers that don't need to handle multiple VLANs themselves. When a device connects to an access port, all its traffic is automatically associated with that port's configured VLAN without the device needing to be VLAN-aware.
For example, if a switch port 5 is configured as an access port in VLAN 10, any computer plugged into that port will only communicate with other devices in VLAN 10. A packet leaving that port will have its VLAN tag removed, appearing as untagged traffic to the connected device.
