Notes on MDI and MDI-X Ports

MDI (Media Dependent Interface) is the IEEE 10BASE-T standard for the interface to the UTP cable. For two 10BASE-T devices to communicate with each other, the transmitter of one device must be connected to the receiver of the other device. This can be achieved by using a crossover cable, or by using one MDI-X port that implements the cross-over internally.

Port 1 through Port 7 (or 15), like all normal hub ports, are configured MDI-X. All NICs (Network Interface Cards) and Router ports are usually by default configured MDI. A simple illustration shows the relationship of cable types to port types:
