If I was asking an ethernet question, I'd rather ask:
1. How do you make a crossover ethernet cable to connect two switches?
(cross the green and orange pairs)
2. What happens if you plug that cable into a pair of gigabit ethernet
switches? (mdix malfunctions, ports negotiate to 100 full, on some
poorly implemented switches the mix of straight and crossed wires
eventually damage the ports so they can no longer do gige)
