Cat 6 supports up to 10 Gb speed.


My current Ethernet port is 10/100, i.e. 100 Mb max speed


If I used a Cat 6 crossover cable, would it be compatible..? 


Or should I use a Cat 5e crossover cable..?

Should be compatible as long as the port is auto-duplex sensing.

It depends on what two devices your connecting and if they actually require a cross over cable and or have auto-negotiation. The link will operate at the lowest negotiated speed and change from cross-over to straight through if the crossover cable is not needed.
