Each layer is served by specialized switches, with the access switch connecting end-user devices, the distribution switch aggregating traffic and enforcing policies, and the core switch acting as the high-speed backbone. This guide will demystify these roles and help you understand. A core switch is the primary switch installed at the backbone of a layered or hierarchical network. This post mainly explores the confusing problem: core switch vs distribution switch vs access switch. End devices connect to the LAN through the access switches. In other words, an access switch forwards traffic between connected devices and the rest of the LAN. The distribution.
