Hello all,

I'm doing course for CCNA and in one lecture teacher showed how to make a crossover cable for Gigabit Ethernet. But as I know Gigabit Ethernet uses all wires of twisted pair cable and each pair is used for both data transmission and reception, so devices that use this standard should be able to transmit and receive on every pin. Then why do we need a crossover cable in such case? Of course I know about Auto-MDI(X) and that it allows to use straight cable in all cases, but it doesn't cancel my question.

Please help.

I did not find the right solution from the internet.
