Question: what is mdix in switch?
Answer: MDIX (Medium Dependent Interface Crossover) is an 8P8C port connection often found on a computer, router, hub, or network switch. Since MDIX is the crossover version of the MDI port, the pins 1 & 2 (transmitting) on an MDI device go to pins 1 & 2 (receiving) on an MDIX device via a straight through cable.
