Command Mode
Interface Configuration (Ethernet - Port 17-18)
Command Usage
Auto-negotiation must be enabled to use the “auto” option for this
command. It must be disabled to force the pinout setting to one of the
fixed modes of “normal” (MDI) or “crossover” (MDI-X).
One side of a link must be configured with MDI pinouts and the other
side with MDI-X pinouts to ensure that signals sent from the tran smit
pins on one side of the link are received on the receive pins by the link
partner. For more information on the signals used for each of these
pinout types, refer to the Installation Guide.
Example
This forces the Port 18 to MDI mode.
