When we where chasing another problem, it was found that packets "disapear" in the Ethernet fabric at Update, sometimes. I think you are referring to when we played with transfers and the performance drops to the floor. That is lost packets because of interface speed differences. They are not really lost, but there only so much that can be queued up in the fabric between interfaces with different speeds. Maybe Johnny can make a small map of the current topology with all involved things and the lan-speeds? That would actually be useful either way, but I'm not sure I can do it easily. Johnny If it was only ONE switch used for all the DECnet speaking things at Update, it would be simple to make a drawing. And with only one device per port, I think any resonable switch has enough buffers to make it work way better. --P (I might even find a switch that does it right and send it to Update)
