What is required when using Auto-MDIX?

Prerequisites for Auto-MDIX Automatic medium-dependent interface crossover (auto-MDIX) is enabled by default. When you enable auto-MDIX, you must also set the interface speed and duplex to auto so that the feature operates correctly. It is not supported on 1000BASE-SX or -LX SFP module interfaces.

How does network auto-negotiation work?

Auto-negotiation is the feature that allows a port on a switch, router, server, or other device to communicate with the device on the other end of the link to determine the optimal duplex mode and speed for the connection. The driver then dynamically configures the interface to the values determined for the link.

Why is auto negotiation not recommended?

Auto-negotiation problems are common; they result from errors on the Ethernet devices connected to the appliance, causing dropped packets, reduced throughput, and session drops. Many users prefer to manually set the speed and duplex mode of the Ethernet NICs so that it will not re-negotiate.

How do I check Auto-MDIX?

To check cable you have to look at connectors at both ends and see if two wires are crossed. A regular cable both ends will have wires that look flat. A cross-over cable one end you will see two wires that are not flat. You will never see a cable with cross-over on both ends.

What could cause a duplex mismatch?

Duplex mismatch may be caused by manually setting two connected network interfaces at different duplex modes or by connecting a device that performs autonegotiation to one that is manually set to a full duplex mode.

What is auto-MDI/MDIX for RJ-45 interfaces?

For RJ-45 interfaces, the default auto-negotiation setting also includes the Auto-MDI/MDIX feature. Auto-MDI/MDIX eliminates the need for crossover cabling by performing an internal crossover when a straight cable is detected during the auto-negotiation phase.
