Fiber Distributed Data Interface (FDDI)

["ANSI"] standardized this link layer technology based on fiber optics (as the name implies).

This technology is obsoleted by ["Ethernet"], but still (rarely) used today.

It is specified by [ various INCITS specifications] - look for "Fibre Distributed Data Interface" in that list.

See [ Ethereal: Supported Capture Media] page for Ethereal capturing support on various platforms.

See [ the Wikipedia article on FDDI] for further technology details.

FDDI sends network packets from the sending host to one (["Unicast"]) or more (["Multicast"]/["Broadcast"]) receiving hosts.


XXX - add a brief description of FDDI history

Protocol dependencies

  • FDDI is the lowest software layer, so it only depends on hardware.

Example traffic

XXX - Add example traffic here (as plain text or Ethereal screenshot).


The FDDI dissector is party functional; it can dissect the FDDI header, and data packets, but does not, for example, dissect SMT packets.

Preference Settings

(XXX add links to preference settings affecting how FDDI is dissected).

Example capture file

XXX - Add a simple example capture file. Keep it short, it's also a good idea to gzip it to make it even smaller, as Ethereal can open gzipped files automatically.

Display Filter

A complete list of FDDI display filter fields can be found in the [ display filter reference for FDDI].

  • Show only the FDDI-based traffic:


    Show only the FDDI-based traffic to and from FDDI MAC address 08:00:08:15:ca:fe: 

Capture Filter

  • Capture only the FDDI-based traffic to and from FDDI MAC address 08:00:08:15:ca:fe:

     fddi host 08:00:08:15:ca:fe
