Auto-MDIX

From Wikipedia, the free encyclopedia

Auto-MDIX, which stands for Automatic medium-dependent interface crossover, is a computer networking technology developed by HP. It automatically detects the required cable connection type (straight-through or crossover) and configures the connection appropriately, thereby obviating the need for crossover cables to interconnect switches or connecting PCs peer-to-peer. When it is enabled, either type of cable can be used and the interface automatically corrects any incorrect cabling. For Auto-MDIX to operate correctly, the speed on the interface and duplex setting must be set to "auto".
