AutoMDI-X

Distinguishing automaticall whether at functional one which the hub and the switch have,the port of the communication partner
MDI or MDI-X, the function which connects with appropriate method. Also AutoMDI-X you say.

The portof Ethernetequipmentsuch asnetworkcard andhub(the entry of the connector), there are 2 types of MDI and MDI-Xfromthe differenceof allotment of sending and receiving of the terminal. As for both sending and receiving is arranged exactly conversely, as for formerin the network card and the like, latteris usedin the hub and the like.You usethe straightcable in the connectionof MDI and MDI-X,MDI andyou arenecessary to use the crosscable inthe connection of MDI-X, but as for such proper use because it is difficult,the hub recognizing this difference automatically, the mechanism which is absorbed was devised. This is Auto MDI/MDI-X. If the hub and the likeof Auto MDI/MDI-X correspondence is used,whenconnecting the computer,whendoingcascade connectionwith the hub, it does not consider the difference and the like of the cable the ? it does not have.
