By default auto MDIX is off. Also Auto MDIX is not supported on 1000 BASE-SX or -LX SFP interfaces.

To turn Auto MDIX on on an interface use this (yes you need to set speed and duplex to auto also):

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

To turn it off:

Switch# configure terminal
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# speed <100/1000/auto>
Switch(config-if)# duplex <half/full/auto>
Switch(config-if)# no mdix auto
Switch(config-if)# end

On a 3550, you don't have the mdix auto command.
