Protocol dependencies

  • ["COTP"]: Typically, PRES uses ["COTP"] as its transport protocol.
  • XXX - is ["CLTP"] also used as transportation protocol?

Example traffic

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


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.
