With Ethernet, all kinds of things will "work" as long as long as your
network is lightly loaded and/or stays a long way away from the various
limits.  The day it stops working for no obvious reason will be painful.

The information presented in the DEC "Networks and Communications Buyer's
Guide" is generally reasonable and the names match the toys you're using
or can be mapped onto their clones.  It's available free from your DEC
sales office...

There's also comp.dcom.lans where the issue of DELNI cascades has been
discussed extensively at least once...
