Hard Coded Speed/Duplex versus "Auto"

What is the bottom line regarding hard coded settings versus "auto" settings for LAN speed and duplex. I have heard valid arguments for both sides...

Re: Hard Coded Speed/Duplex versus "Auto"

Auto-negotiation is a lot more reliable than it used to be. So the folks who had to put up with its flakiness in the past say hard-code everything while the folks who have good experiences with it today say use auto. Generally, I think that auto on workstations and hard-coding on switch/router (up)links is the wise path. Servers sit somewhere in the middle. I usually leave those on auto, though some others like hard-coding them as well.

Always use Cisco's Best practices doc on your switches. www.cisco.com/warp/public/473/103.html

It says to go with auto unless there is a problem.
