Why does a switch flood a frame?
A switch floods a frame when it doesn't have the destination MAC address in its MAC address table. The frame is then forwarded out of all interfaces except the one it was received on in an attempt to find the correct host.
What switching method examines the destination MAC address as the frame is being received and then begins forwarding the frame prior to receiving the entire frame?
