Link Aggregation (LAG) allows multiple physical links to be combined into one logical connection, increasing bandwidth and redundancy. It prevents single-link failures from disrupting network traffic. Instead of one cable at 10G, you might have: Of course, as we'll see later, each flow does not get 40G, but in aggregate, you can use all the links. This article will delve into the fundamental concepts of MLAG, explore its diverse applications, and. As devices are added to a small network, more switch ports are needed to connect those devices to the network.
