Hmmm.  We recently evaluated a product called NQA The Prophet that is
basically a Physical/MAC layer LAN analyser.  The first thing this
product told us was that the MCI on the cisco for this LAN was
clocking 3 times too fast.  I talked to cisco about this and they
requested information on this analyser.  After looking over what I had
sent them, they did admit that this was a problem with some of their
earlier interfaces.  I asked them how one could differentiate these
interfaces from their newer ones and have since not gotten a response.

Anyway, could this problem manifest itself in the symptoms mentioned
above and in earlier notes?  As this is a physical layer problem,
tools like the Sniffer, LANWatch, etc wouldn't catch it.  Just a
thought.
