An aggregate switch is a high-capacity network switch that consolidates connections from multiple access switches, acting as a central point for managing network traffic and providing enhanced bandwidth capabilities. It is essential for larger networks requiring efficient data flow. The primary function of an aggregation switch is to aggregate and forward data from multiple network devices, such as access. An aggregation switch sits in the middle tier of a network, collecting traffic from multiple smaller access switches and funneling it upward to the core. This arrangement increases throughput beyond what a single relationship could sustain, offers redundancy in case one of the links.
