Has this happened to you with equipment designed and manufactured the past
5 years?
For me this was a problem with equipment released around 2000, since
2005-2007 or so I haven't seen a single problem that I can recall.
I blame part of this problem on Cisco who was especially bad at handling
autoneg. I remember in 1998 when we couldn't even get link up between a
100 meg LE interface on a Sun and a (I believe) 3500XL. We had to use a
hub in between to get link at all. Even worse, different port blocks on
the 3500XL behaved differently.
