System Requirements

Cisco WS-C1400 CDDI/FDDI Concentrator

  • Cisco WS-C1400 Copper Distributed Data Interface (CDDI)/FDDI concentrators' modular design allows between four and 32 CDDI and/or FDDI ports.

  • Cisco WS-C1400 CDDI/FDDI concentrator release notes.

Cisco WS-C1100 CDDI/FDDI Concentrator

  • Cisco WS-C1100 CDDI/FDDI concentrator supports singlemode fiber (SMF) and multimode fiber (MMF) FDDI connectivity and CDDI/multilevel transmission (CDDI/MLT-3).

  • Cisco WS-C1100 CDDI/FDDI concentrator release notes.

Catalyst 5000 Series Switch

  • 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 engine software release 1.3 or later.

  • Catalyst 5000 series FDDI software release notes.

Catalyst 1900/2820 Series Switch

Catalyst 1600 Series Switch

  • Catalyst 1600 series Token Ring switch supports WS-C161F FDDI module.

  • The FDDI module enables you to connect the Catalyst 1600 to file servers, routers, concentrators, or other Catalyst 1600 devices, on FDDI networks.

  • Catalyst 1600 series Token Ring switch supports FDDI module in software release 1.3 or later.

Cisco 7000 Series Router

  • Cisco 7000 series routers support both FDDI half-duplex port adapters and full-duplex port adapters, which provide interfaces for both SMF and MMF optic cable.

  • Cisco 7000 series routers support half-duplex and full-duplex port adapters in Cisco IOS release 11.1x or later.

Cisco 4000 Series Router

  • Cisco 4500-M and 4700-M supports one-port single attachment multimode FDDI Network Processor Modules (NPMs), and one-port dual attachment SMF/MMF FDDI NPMs.

  • Cisco 4000 series routers supports FDDI in Cisco IOS release 11.2x or later.
