What is auto-negotiation (N-Way)?
The IEEE’s auto-negotiation technology, also known as N-way, can tell what speed the other end of the wire is capable of. The hub or NIC will then automatically adjust its speed to the highest common denominator, that is, the fastest speed that both are capable of. Auto-negotiation defines five modes: 10Base-T half duplex, 10Base-T full duplex, 100Base-TX half duplex, 100Base-T4, and 100Base-TX full duplex. It automatically switches to the correct mode while common mode with the highest performance is determined. Auto-negotiation passes control of the able to the appropriate technology and becomes transparent until the connection is broken. The priority of five modes from top to lower are: (1) 100Base-TX full duplex (2) 100Base-T4 (3) 100Base-TX half duplex (4) 10Base-T full duplex (5) 10Base-T half duplex.
