Network Switch MAC Address Table Learn, Flood & Forward Explained
How a Network Switch Actually Works
In this video, we break down exactly how a network switch learns your entire network from a completely blank slate no configuration required. We walk through the MAC address table, the three core rules of switching (Learn, Flood & Forward), and a step-by-step real-world example of a switch going from zero knowledge to full intelligence. We also cover why hubs create a unique limitation and what the 300-second aging timer means for your network long-term.
