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 [http://www.incits.org/list_INCITS.htm various INCITS specifications] - look for "Fibre Distributed Data Interface" in that list.
See [http://www.wireshark.org/media.html Wireshark: Supported Capture Media] page for Wireshark capturing support on various platforms.
See [http://en.wikipedia.org/wiki/Fddi 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
- FDDI is the lowest software layer, so it only depends on hardware.
XXX - Add example traffic here (as plain text or Wireshark screenshot).
The FDDI dissector is party functional; it can dissect the FDDI header, and data packets, but does not, for example, dissect SMT packets.
(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 Wireshark can open gzipped files automatically.
A complete list of FDDI display filter fields can be found in the [http://www.wireshark.org/docs/dfref/f/fddi.html display filter reference for FDDI].
