MACsec (Media Access Control Security)is a Layer 2 encryption protocol designed to secure Ethernet communications. It provides confidentiality, integrity, and replay protection for data transmitted over wired networks. The IEEE standard corresponding to MACsec is802.1AE, which defines the protocol's mechanisms for encrypting and authenticating Ethernet frames.Other options refer to unrelated standards:
802.1ab:Defines Link Layer Discovery Protocol (LLDP) for network discovery.
802.1p:Specifies priority tagging for Quality of Service (QoS).
802.1at:Defines Power over Ethernet Plus (PoE+).
