Command Modes Interface configuration Command History Release 12.2(25)SEF Modification This command was introduced. 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 10/100/1000 Mbps interfaces and on 10/100/1000BASE-T 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 gigabitethernet0/1 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.
