Some controllers don't do well with auto negotiate. You'll see the
symptoms at the data level. Do an analy/system sho lan/count and you'll
see things like alignment errors. Better to hard code 100/full or the
like on BOTH the controller and Cisco switch.

Since network managers EVER admit to having problems, get a CISCO
show tech will show a lot of information (NONE OF IT SECURE) but it
will show the speed and duplex for each and every port.

Absolutely make sure you are up to date on LAN ECOs, especially for
newer (like DE600) controllers.
