Ethernet Autonegotiation Best Practices

Category: Security, Networking and Communications

Overview This paper discusses the advantages of using Ethernet autonegotiation when connecting Fast Ethernet (100 Mbps) and Gigabit Ethernet (1000Mbps) NICs to network switches, routers, and hubs. It emphasizes Sun's recommendation to leave Ethernet autonegotiation enabled (default) when connecting devices that are compliant with IEEE 802.3 standards. Link failures, network delays, performance problems, and network troubleshooting difficulties can be alleviated and optimal link configuration is achieved with the correct implementation of Ethernet autonegotiation. Using autonegotiation is the IEEE 802.3 standard and customers are encouraged to follow the "intent" of IEEE 802.3u/z standards and implement autonegotiation in their Ethernet environments.
