Core switches primarily connect to distribution (aggregation) switches, forming the backbone of a network, rather than directly to end-user devices.
A core switch sits at the top of a hierarchical network, forming the core layer of the network architecture . Its main role is to aggregate and route traffic between different network segments with high speed and low latency. Unlike access switches, which connect directly to end-user devices like computers, printers, and IP phones, the core switch typically connects to distribution or aggregation switches . These distribution switches, in turn, collect traffic from multiple access switches and forward it to the core switch for high-speed routing across the network .
In some enterprise networks, core switches may also connect directly to servers, data centers, or high-capacity routers to facilitate fast access to critical resources or external networks . However, direct connections to individual end-user devices are uncommon, as the core switch is optimized for aggregated traffic management rather than individual device connectivity .
This hierarchical design ensures that the network remains scalable, efficient, and resilient, with the core switch serving as the central hub for all major traffic flows.
As a result, a handful of ports is usually enough for a core switch. Meanwhile, access switches often need
