View Full Version : MDI/MDIX

Am I correct in guessing that ports that support MDI/MDIX can act as the "uplink" port when connected to a router/modem? (Instead of having dedicated uplink ports?).

I faced that problem about a year ago and I think it was Erayd that put me right. I think he said that MDI/MDIX accommodates cable wiring, a kind of physical thing. It can't change the logical function of a port from LAN to WAN

MDI/MDIX means that the ethernet ports on a switch or router can autodetect if the cable you have plugged in is a straight through / patch cable or a crossover cable.
AFAIK all recent switches or routers have this feature built in now.
It used to be that if you wanted to connect two switches, or a switch and a router, you had to use the uplink port. If there was no uplink port on either then you had to use a crossover cable.
