Gigabit Ethernet Auto-Negotiation

The Auto-Negotiation standard allows devices based on several Ethernet standards, from 10BaseTto 1000BaseT, to coexist in the network by mitigating the risks of network disruption arising from incompatible technologies. This capability helps ensure a smooth migration path from Ethernet to Fast Ethernet and Gigabit Ethernet. This article provides an in-depth explanation of auto-negotiation and its functioning and also discusses special cases that may be encountered
