Aggregation switches, often referred to as distribution switches, play a pivotal role in the hierarchical network architecture. These switches serve as intermediaries between access switches and core switches, aggregating data from multiple access points and directing it towards. An aggregation switch is a network device that consolidates traffic from multiple access switches, wireless access points, or other edge devices and forwards it to core switches or routers. It is essential for larger networks requiring efficient data flow. This arrangement increases throughput beyond what a single relationship could sustain, offers redundancy in case one of the links. 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. In a traditional three-tier network design, it's the policy hub: the place where traffic gets organized, filtered, and routed between different.
