Layer 2 switches: Network devices that operate at the data link layer (Layer 2) of the Open Systems Interconnection (OSI) model. They are responsible for forwarding data frames between devices on a local network based on the device’s MAC addresses. Layer 2 switches are central to local network operation and performance, but they must be properly configured and managed to prevent potential security issues such as MAC flooding or spoofing attacks.
