I just reported on what I'd read and asked for some actual data to back up what appears on the surface to be a wild rumor fired largely by war stories of old equipment built to a different spec than the current one. Do *you* know with any certainty if autonegotiation problems are due to old hardware, mis-configuration (aka pilot error), or just brain-dead equipment? How about sharing what you know instead of challenging my trouble-shooting skills? This is freebsd-questions. We're supposed to be helping each other here. -Mitch >I'ts a nice story, just wait 'till *YOU* have a problem with >autonegotiation, will you be smart enough to check that first >or will your network suffer endless packet loss...until you >call in a consultant...like David Greenman? > >Take care, >Randy Katz > >> >Also I'm curious about your statement about autonegotiate being >> >notorious.
