MDI/MDIX — Defines the Media Dependent Interface (MDI)/Media
Dependent Interface with Crossover (MDIX) status on the port. Hubs and
switches are deliberately wired opposite the way end stations are wired, so
that when a hub or switch is connected to an end station, a straight through
Ethernet cable can be used, and the pairs are matched up properly. When
two hubs or switches are connected to each other, or two end stations are
connected to each other, a crossover cable is used to ensure that the
correct pairs are connected. The possible field values are:
-
Auto
— Use to automatically detect the cable type.
-
MDI
— Use for end stations.
-
MDIX
— Use for hubs and switches.
