How do I configure auto-negotiation on Cisco router?
negotiate auto To enable the autonegotiation protocol to configure the speed, duplex, and automatic flow-control of the Gigabit Ethernet interface, use the negotiate command in interface configuration mode. To disable automatic negotiation, use the no negotiate auto command.
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 set auto negotiation in Windows 10?

What is port configuration?
The Port Configuration window displays the port configuration and provides access to a window for modifying port configuration. Port configuration values are: Port. Slot and port number for each port installed in the switch (for example, A1 means the first port in slot A).
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 the auto-MDIX feature on the switch?
The auto-MDIX features apply only to copper port switches using twisted-pair copper Ethernet cables. Syntax interface mdix-mode[ auto-mdix| mdi| mdix] auto-mdix The automatic, default setting. This configures the port for automatic detection of the cable (either straight-through or crossover.)
What is the manual mode setting of an MDI-X device?
The manual mode setting that configures the port for connecting to either a switch, hub, or other MDI-X device with a crossover cable, or to a PC or other MDI device with a straight-through cable. Syntax show interfaces config Lists the current per-port Auto/MDI/MDI-X configuration.
What is the default mode of the MDI port?
The automatic, default setting. This configures the port for automatic detection of the cable (either straight-through or crossover.) mdi The manual mode setting that configures the port for connecting to either a PC or other MDI device with a crossover cable, or to a switch, hub, or other MDI-X device with a straight-through cable.
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.
