Telecom Routers Switches Interview Question:

What is Auto-Negotiation function?

Submitted by: Administrator

Auto-negotiation is a mechanism that takes control of the
cable when a connection is established to a network device.
Auto-negotiation detects the various modes that exist in
the device on the other end of the wire, and advertises it
own abilities to automatically configure the highest
performance mode of interoperation.
Auto-negotiation automatically switches to the correct
technology, such as 10BASE-T, 100BASE-TX, or a
corresponding Full Duplex mode. Once the highest
performance common mode is determined, Auto-negotiation
passes control of the cable to the appropriate technology
and becomes transparent until the connection is broken.
