Cisco WS-C1100 CDDI/FDDI concentrator supports singlemode fiber (SMF)
and multimode fiber (MMF) FDDI connectivity and CDDI/multilevel transmission
Cisco WS-C1100 CDDI/FDDI concentrator
Catalyst 5000 series switches support CDDI module (WS-X5103), FDDI
module MMF (WS-X5101), and FDDI module SMF (WS-X5104).
The FDDI/CDDI modules run their own software image, in addition to
the supervisor engine software image.
Catalyst 5000 series switches support FDDI/CDDI modules in supervisor
release 1.3 or later.
