Do you need a special crossover cable when connecting two auto MDI-X devices?
- Sometimes, depends on equipment manufacturer
- Yes
- Yes, CAT5E UTP is needed
- No
EXPLANATION
A medium dependent interface (MDI) describes the interface (both physical and electrical/optical) in a computer network from a physical layer implementation to the physical medium used to carry the transmission. Ethernet over twisted pair also defines a medium dependent interface crossover (MDI-X) interface. Auto MDI-X ports on newer network interfaces detect if the connection would require a crossover, and automatically chooses the MDI or MDI-X configuration to properly match the other end of the link.
