CONNECTION-ORIENTED PRESENTATION PROTOCOL (PRES)

This protocol is defined as ITU recommendation X.226

It is part of the IsoProtocolFamily.

History

This protocol is part of the OSI stack.

Protocol dependencies

Example traffic

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

Ethereal

The PRES dissector is generated by the ["Asn2eth"] compiler.

Preference Settings

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

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Keep this file 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 PRES display filter fields can be found in the [http://www.ethereal.com/docs/dfref/p/pres.html display filter reference]
