Note
The auto-MDI/MDI-X feature on the 10/100/1000Base-T ports
automatically configures the MDI/MDI-X setting when a link is
established with an end node. Available when a port is at the default
setting of Auto-Negotiation, this feature allows you to use a straight-
through twisted pair cable when connecting any type of network
device to a port.

Disabling Auto-Negotiation on a port and setting the speed and
duplex mode manually also disables the auto-MDI/MDI-X feature. A
port where Auto-Negotiation has been disabled defaults to MDI-X.
Disabling Auto-Negotiation may require manually configuring a
port’s MDI/MDI-X setting or using a crossover cable.
