We are in the process of bringing up a moderate-sized FDDI ring with
concentrators, routers, and a few hosts.

We have noticed that we are seeing packet duplication on our ring.  When
I run a ping from one station to another I see between 1-10 % packets
duplicated.

My first reaction was that I should be able to pin this down easily by
SNMP'ing the SMT info from the various nodes (including concentrators).

Unfortunately, every bit of info I get looks clean to me--no error 
counters (at least none that are large and none that increment after
I see a duplicate packet).

Has anyone else seen something like this on an FDDI ring?  Any things in
particular I should look for?

	Thanks very much,
