Traditional switching operates at layer 2 of the Open Systems Interconnection (OSI) model, where packets are sent to a specific switch port based on destination MAC addresses. In practice, Layer 2 switches fit access-layer endpoint connectivity, while Layer 3 switches are better for inter-VLAN routing. This article outlines the difference between layer 2 and layer 3 switches and the appropriate use cases for each. Sign in with your Cisco SSO or create a free account to start training. It especially utilizes MAC addresses to direct information packets between devices that are on the exact same network. ·. Let's talk about the real MVP of any serious network—the core switch. A ton of folks get halfway through a build and suddenly go, “Wait. is this thing Layer 2 or Layer 3? Did I pick the wrong one?” Trust me, picking wrong hurts later.

A Layer 2 switch is a network device that forwards traffic based on MAC (Media Access Control) addresses. When a frame arrives on a port, the switch reads the destination MAC address, consults its MAC address table, and forwards the frame to the correct port. It includes the following topics: Access layer switches are primarily deployed in Layer 2 mode in the data center. The aim is to provide application scenarios that suit customer needs and company size with a focus on recommendations from the LANCOM switch portfolio. The access layer plays a critical role in connecting end devices—such as computers, printers, IP phones, and wireless access points—to the rest of the enterprise.
