The choice between a tagged and untagged port is not arbitrary; it depends on whether the connected device is network-aware, like a router or another switch, or a simple endpoint, like a desktop computer or printer. Feature Tagged Port (Trunk) Untagged Port (Access) Primary Use Connecting switches, routers, and servers that handle multiple VLANs Connecting end-user devices like PCs, printers, and IP phones Frame Handling Adds and reads VLAN tags (802.
Access Port Untagged Frame Assignment and VLAN Tag Handling
This distinction is critical for isolating traffic, ensuring security, and designing a scalable network architecture that aligns with business requirements. When a device connected to an untagged port sends a frame, the switch automatically assigns the port's native VLAN ID to the frame before forwarding it.
On the receiving end, when a frame arrives on an untagged port, the switch strips the VLAN tag from the frame, delivering the pure Ethernet payload to the connected device. Defining the Core Concepts At the heart of VLAN implementation lies the configuration of switch ports.
Access Port Untagged Frame Assignment and VLAN Handling
These terms define how a network switch interface handles VLAN (Virtual Local Area Network) traffic, dictating whether frames enter or leave the network with a specific VLAN identifier. Understanding the difference between a tagged and untagged port is fundamental for anyone managing a network, whether in a corporate data center or a home environment.
