To enable the interface to communicate with its peer, make sure that its transmit pins are connected to the
remote receive pins. If the interface can detect the connection cable type, set the interface in auto MDI
mode. If not, set its MDI mode using the following guidelines:
When a straight-through cable is used, set the interface to work in the MDI mode different than its
peer.
When a crossover cable is used, set the interface to work in the same MDI mode as its peer, or set
either end to work in auto mode.
To set the MDI mode of an Ethernet interface:

By default, a copper Ethernet
interface operates in auto mode to
negotiate pin roles with its peer.
