Protocol dependencies

Example traffic

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


The DIAMETER dissector is fully functional, DIAMETER uses internal value strings to display AVP names etc or if LIBXML is present on the system a XML dictionary which is located in the Diameter folder, the XML library is out of date.

Preference Settings

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

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here. 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 DIAMETER display filter fields can be found in the [ display filter reference]
