There is debate at work regarding network Ethernet auto-negotiation.
I'm the newcomer.  Historically they say they had problems with auto-neg
and their cisco gear (catalist) and now manually set all switch ports
and server NICs to full/full.   I've never heard of such a policy.  It
seems to make extra work for all parties since all gear defaults to
auto/auto.  Additionally, I spent some time trouble shooting a Linux
server that I had newly configured for bonding.  I could not force the
NICs to full/full.  When I had the cisco guy change the switch ports to
auto/auto the bonding worked instantly.

Should this manual configuration of full/full be the exception or the
rule?
