An aggregation switch consolidates data traffic from multiple network access switches into a single high-bandwidth link directed toward a core network or data center. The aggregation layer serves as the convergence point for multiple access layer switches and is responsible for handling all. Switch aggregation, also known as link aggregation or trunking, is a method used in computer networking to combine (aggregate) multiple network connections in parallel. This arrangement increases throughput beyond what a single relationship could sustain, offers redundancy in case one of the links. Link aggregation is a way of bundling a bunch of individual (Ethernet) links together so they act as a single logical link. A fundamental for effective switch management, if you have a switch with a whole lot of Gigabit Ethernet ports, you can connect all of them to another device that also has a. Core switches set up a CSS that functions as the core of the entire campus network to implement high network reliability and forwarding of a large amount of data.
