Usage Guidelines
When auto-MDIX is enabled, the interface automatically detects the required cable connection type
(straight-through or crossover) and configures the connection appropriately.
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 the connected
interfaces, link up occurs, even if the cable type (straight-through or crossover) is incorrect.
Examples
This example shows how to enable auto-MDIX on a port:
Device# configure terminal
Device(config)# interface gigabitethernet1/0/1
Device(config-if)# speed auto
Device(config-if)# duplex auto
Device(config-if)# mdix auto
Device(config-if)# end
