PROFINET - Media Redundancy for RealTime (MRRT)

XXX - add a brief MRRT description here

History

XXX - add a brief description of MRRT history

Protocol dependencies

• PROFINET/RT: Typically, MRRT uses PROFINET/RT as its "transport" protocol. The PN/RT frame ID for MRRT traffic is 0xFF60.

Example traffic

XXX - Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot).

Wireshark

The MRRT dissector is fully functional.

Preference Settings

There are no MRRT specific preference settings.

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 Wireshark can open gzipped files automatically.

• SampleCaptures/PROTO.pcap

Display Filter

A complete list of MRRT display filter fields can be found in the display filter reference

Show only the MRRT based traffic:

 pn_mrrt 

Capture Filter

You cannot directly filter MRRT protocols while capturing.

External links

• add link to MRRT specification and where to find additional info on the web about it, e.g.:

• RFC 123 The RFC title - explanation of the RFC content.
