I just installed our first FDDI board in our Cisco, and surprise..
it doesn't work. It looks like it cannot enter into the ring. I had it
installed at first in our ring with 3 Interphase FDDI boards, but when that
didn't work I tried looping back the Cisco to itself. Even that did not
work. I configured it:
	interface fddi0
	ip address 130.37.16.1 255.255.255.0
	no shutdown

The router is now very slow, the 'show proc' output shows that the PHY-A
and PHY-B processes take all the time. I did a shutdown on the interface
and the router is back to normal.

Here is some other data: if this means anything to more experienced
FDDI customers I would be much appreciated.
