About This Architecture

Switch trunk link carrying multiple VLANs across two managed switches using a single physical connection. SW1 and SW2 are interconnected via trunk ports (Eth 1/1 and Eth 1/24) that encapsulate traffic for VLAN 10, VLAN 20, and VLAN 30, enabling inter-VLAN communication while maintaining logical network segmentation. This trunk configuration reduces physical cabling requirements while preserving broadcast domain isolation across the LAN. Fork this diagram to customize port assignments, add additional VLANs, or model failover trunk links for redundancy. Trunk links are foundational to scalable enterprise network design and support dynamic VLAN membership across multiple access switches.

People also ask

How do I design a trunk link between two switches to carry multiple VLANs?

A trunk link uses a single physical connection between switches (SW1 Eth 1/1 to SW2 Eth 1/24) to carry traffic for multiple VLANs (10, 20, 30) simultaneously through VLAN tagging. This reduces cabling while maintaining logical network isolation and enables efficient inter-VLAN routing across your LAN infrastructure.
