Configuring Auto Negotiation
Autonegotiation is a signalling mechanism in which two devices connected over Ethernet can choose common transmission parameters such as speed, duplex, mode and flow control.
In this process, the connected device first shares its capabilities regarding these parameters and then chooses the highest performance mode that both support.
