None, there is no communication.  For example, if I attempt to telnet,
I'll see the link activity led blink on both ends, but no collisions no
communication.

Both cards have leds which indicate they are at 100/full duplex.  The
switch also indicates that both cards are at 100/full duplex.

You are correct in that the switchs don't support snmp.  What exactly do
you mean by 'watch your ifconfig?'  Watch Ifconfig for collisions? 
There's no data transfer at all.

I doubted it as well, but replaced them just the same, with no
difference.

How is this done??
