At least two and I think all 3 of these organizations do not claim to test
anything but the link layer and below.  They have varied SMT and PCM test
suites and procedures, but at least one of the three will just look blank
if you talk about IP; they disavow any knowledge of TCP/IP or any other
useful protocol.  ("Useful" as in the reason someone might buy the stuff.)
Interop itself relies on the other two and on the vendors themselves to
test things.  At least this was my experience last year and the year
before, and it seems the same so far this year.

There was X over TCP/IP/FDDI at Interop90, but there was no more testing
than workstation vendors yelling to each other, "Hey, do you want to try it
now?"  Fortunately, TCP/IP works fine, provide the lower layers even half
work.
