Usage Guidelines When you enable auto-MDIX on an interface, you must also set the interface speed and duplex to auto
so that the feature operates correctly.
When auto-MDIX (and autonegotiation of speed and duplex) is enabled on one or both of connected
interfaces, link up occurs, even if the cable type (straight-through or crossover) is incorrect.
Auto-MDIX is supported on all 10/100 and 10/100/1000 Mb/s interfaces. It is not supported on
1000BASE-SX or -LX small form-factor pluggable (SFP) module interfaces.
Examples This example shows how to enable auto-MDIX on a port:
Switch# configure terminal
Switch(config)# interface gigabitethernet1/1
Switch(config-if)# speed auto
Switch(config-if)# duplex auto
Switch(config-if)# mdix auto
Switch(config-if)# end
You can verify the operational state of auto-MDIX on the interface by entering the show controllers
ethernet-controller interface-id phy privileged EXEC command.
