In modern networking environments, managing traffic efficiently across different departments, floors, or even buildings is a core requirement. Virtual LANs (VLANs) were introduced to segment broadcast domains at Layer 2 of the OSI model without needing separate physical infrastructures. However, when multiple VLANs need to communicate across switches, a challenge arises. To tackle this, network professionals use trunk links, which can carry traffic from multiple VLANs over a single physical connection. To automate the setup and negotiation of trunk links between switches, Cisco developed a protocol known as Dynamic Trunking…
