I work in network operations at a large, high-end computer show every year. We typically have over 100 network drops, most at 1 Gb/s or higher and multiple OC-192s (10 Bb/s SONET) to the outside world. Every year when the drops are connected, a number don't work. The problems are ALMOST always auto-negotiation. This is new, state-of-the-art equipment from major vendors of both switches and routers. The problem does not seem to be getting worse, but it is not really improving, either. The problems are NOT close to the majority, but they are far from rare. -- R.
