Consequently, a single physical interface on a tagged port can transport a complex mix of segregated network segments, making it the essential backbone for connecting switches or linking a switch to a router that handles inter-VLAN routing. This tag acts like a virtual label, identifying the specific VLAN to which the frame belongs as it traverses the trunk link.
Server Connection Tagged Port Setup: Configuring Trunk Links for VLAN Traffic
Misconfiguring these settings is a common source of connectivity issues, where devices can see broadcasts but not specific IP traffic, or where traffic from one VLAN leaks into another. It accomplishes this by inserting a 4-byte VLAN tag, known as an IEEE 802.
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. The configuration is typically managed through the switch's command-line interface or web-based GUI, where an administrator selects whether a port is an access port (untagged) or a trunk port (tagged).
Configuring a Tagged Port for Server Connections
How Tagged Ports Function A tagged port, often referreduced to as a trunk port, is designed to carry traffic for multiple VLANs simultaneously. 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.
