Token Ring (IEEE 802.5)

Token Ring is a local area networking technology originally devised by IBM. It has largely been replaced by Ethernet, but some Token Ring installations still exist.

It is specified by various IEEE 802.5 specifications.

Token Ring sends network packets from the sending host to one (Unicast) or more (Multicast/Broadcast) receiving hosts.

Information how to capture on a Token Ring network can be found at the CaptureSetup/TokenRing page.

History

XXX - add a brief description of Token Ring history

Protocol dependencies

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

Example traffic

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

Wireshark

The Token Ring dissector is fully functional.

Preference Settings

(XXX add links to preference settings affecting how Token Ring 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.

Display Filter

A complete list of Token Ring display filter fields can be found in the display filter reference for Token Ring and display filter reference for Token Ring Media Access Control

  • Show only the Token Ring-based traffic:

     tr 

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

     tr.addr==08.00.08.15.ca.fe 

Capture Filter

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

     tr host 08:00:08:15:ca:fe
