Ethernet is the IEEE 802.3 family of wired LAN technologies that defines cabling, signaling and the frame format used to carry data between devices.
Layer 2 is the data link layer of the OSI model, where Ethernet frames move between devices on the same network segment using MAC addresses and…
Layer 3 is the network layer of the OSI model, where IP addressing and routing happen and where layer 3 switches forward traffic between subnets.
Link aggregation bundles several parallel Ethernet links into one logical link, adding capacity and redundancy between switches, servers and storage.
A managed switch is an Ethernet switch that can be configured and monitored, offering VLANs, QoS, link aggregation and security controls on each port.
A network switch forwards Ethernet frames between devices in a LAN, learning MAC addresses so each frame reaches only its intended port.
Spanning Tree Protocol is a Layer 2 switching protocol that blocks redundant Ethernet links to prevent loops while keeping backup paths ready for failover.
