I could be wrong here as I am not as techincal as I used to be but
enabling port fast speeds the recovery transition from spanning tree's
blocked state. Normally it will go through two other phases, listening
and maybe learning, not sure. Port fast moves it from a full span tree
blocked state
Sounds like a duplex mismatch somewhere.
Are you sure the DTU is running @ 100 Full duplex?
You know, it's amazing just how many times people assume it must be a
duplex and/or speed auto-negotiation issue whenever we have any sort of
network performance issue in Sun hardware. Be it with Sun
Force the switch that your sun ray on to 100 full or put it on a 10/half
hub. Watch the SR go to 10 half and exhibit the exact problems that
were explained.
Also, it's well documented that Cisco switches and Sun servers had a
serious issue performing auto-neg correctly a few years back.
Not that I think the duplex neg has anything to do with this particular issue
but I can share this with regards to Cisco switches. My 170's both mate to a
Cisco 3750 and I have them hard coated in the switch to full. I did have a
negotiation issue at first but that was to do with the fact that

Port fast should be enabled, which is basically turning off spanning tree.
