Data Frame Forwarding: Master Efficient Network Switching Techniques (Updated 2025)
Ethernet switching is a cornerstone of modern networking, enabling efficient data transfer in local area networks (LANs). For CCNA and CCNP students, understanding switching methods like store-and-forward and cut-through is critical for designing and troubleshooting networks. This article explores the evolution from Ethernet bridges to advanced LAN switches, focusing on frame forwarding techniques, their characteristics,...

Switching Fundamentals – Everything to Know
An Ethernet switch is a Layer 2 device. Therefore, the switch uses MAC addresses for switching decisions. It is unaware of the protocol being carried in the data portion of the frame, such as an IPv4 packet. The Ethernet hub repeats bits out of all ports except the incoming port, but an Ethernet switch consults...
