Since other 2 lower layers rely upon it, core layer switch must be a highly redundant and powerful layer 3 switch to ensure efficient high-speed and reliable data transmission. What Is Core Switch?Ĭore switch occupies in the topside layer of the enterprise networking (core layer), which functions as backbone switch for LAN access and centralizes multiple aggregation to the core. Today we will introduce core switch and what’s the difference between core switch vs normal switch. In my last post – What Is Distribution Switch and Why Do We Need it? – the role of distribution switch functioning multiple switch aggregation and inter-VLAN routing has been illustrated. As we know, there are normal access/edge layer switch, aggregation/distribution layer switch and core layer switch. Thus locating right switches in your three-layer architecture is the first step to set up a reliable hierarchical internetworking model.

In enterprise network, network switch is always an indispensable component.
