Data Frame Forwarding: Store-and-Forward, Cut-Through, and Fragment-Free Switching
Every switch has to decide exactly when to start forwarding a frame — wait for the whole thing, or start moving it the instant enough information is available. That decision defines the three switching methods every CCNA and CCNP candidate needs to know: store-and-forward, cut-through, and fragment-free. Each represents a different trade-off between reliability and...

Switching Fundamentals: MAC Address Tables and Frame Forwarding Methods
An Ethernet switch is a Layer 2 device, which means it makes every forwarding decision based on MAC addresses, entirely unaware of what protocol is actually carried inside the frame’s payload, whether that’s an IPv4 packet, an IPv6 packet, or something else entirely. This guide covers exactly how a switch builds and uses its MAC...
