Talk to Steve Feldman from MFS. At the October Nanog meeting he
mentioned that their Gigaswitches (not sure if this is was just for
MAE West) were ready to support Full Duplex FDDI and he invited
volunteers to try it.
Unfortunately, the GRF does not yet have a full duplex FDDI interface
available, but when I asked about it, Ascend told me that they had
implemented a CDDI interface in 3 weeks time to gain the business of
of one customer.
