To disable auto-MDIX, use the no mdix auto interface configuration command.
This example shows how to enable auto-MDIX on a port:
Switch# configure terminal
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# speed auto
Switch(config-if)# duplex auto
Switch(config-if)# mdix auto
Switch(config-if)# end
Configuring a Power Management Mode on a PoE Port
For most situations, the default configuration (auto mode) works well, providing plug-and-play
operation. No further configuration is required. However, use the following procedure to give a PoE port
higher priority, to make it data only, or to specify a maximum wattage to disallow high-power powered
devices on a port.
Catalyst 3750-X switches also support StackPower, which allows switch power supplies to share the load
across multiple systems in a stack by connecting up to four switches with power stack cables. See
