MDI/MDIX (Media Dependence Interface – Straight-through/Crossover)
The IEEE 10Base-T standard for the UTP cable interface. The MDI
(straight-through) mode is usually configured to connect to network
terminal equipment, such as a PC. The MDIX mode is usually
configured to connect/uplink to another network equipment, such as
a cable modem, ADSL or HUB.
MDI/MDIX autodetect feature eliminates typical concerns about
crossover cabling, limited uplinks, or to which devices a switch is
linked. The ports automatically sense if they need to function as
straight or crossover ports, thus crossover cables can connect both
PCs and switches or hubs.
