Auto MDI/MDI-X
An RJ-45 twisted pair port on a 10 Mbps or 100
Mbps Ethernet network device can have one of
two possible wiring configurations: MDI or
MDI-X, while the twisted pair port on a switch
or hub is usually MDI-X.
To connect two 10 Mbps or 100 Mbps network
devices together that have dissimilar port
wiring configurations, such as MDI or MDI-X,
you use a straight-through twisted pair cable.
To connect two network devices that have the
same wiring configuration, such as MDI to
MDI, you use a crossover cable.
