A core switch operates at the backbone of a network, forming the core layer in a three-tier architecture consisting of core, distribution, and access layers . Its primary role is to aggregate data from distribution switches and provide high-speed, low-latency forwarding across the network . The core switch does not directly connect to end-user devices; instead, it relies on the distribution layer to collect and manage traffic from access switches and subnets .
In network topology terms, the parent level of a core switch refers to the layer or device that feeds traffic into it. In most enterprise networks:
show cdp neighbors (Cisco) or show lldp neighbors can reveal connected upstream devices, effectively showing the parent layer.The parent level of a core switch is generally the distribution layer, which aggregates traffic from access switches and forwards it to the core. In smaller or collapsed core networks, a distribution switch may also perform core functions. To view the parent level, network diagrams, management interfaces, neighbor discovery protocols, or monitoring software can be used to trace upstream connections and understand the network hierarchy .
