When a single link isn’t enough to handle bandwidth demands or redundancy requirements, port aggregation offers a scalable solution. In this episode, we explain how LACP (Link Aggregation Control Protocol) is used to combine multiple physical interfaces into one logical link known as a port channel or EtherChannel. You’ll learn how LACP negotiates aggregation, prevents loops, and distributes traffic across links based on load-balancing algorithms.

We cover the difference between static and dynamic link aggregation, how to configure active and passive LACP modes, and how to monitor the health of your aggregated links. Port aggregation is commonly used between core switches, servers, and storage systems to boost throughput and ensure fault tolerance. This is a must-know feature for high-performance and redundant network design.
