PROFINET - Media Redundancy Protocol (MRP)
XXX - add a brief MRP description here
History
XXX - add a brief description of MRP history
Protocol dependencies
- Ethernet: Typically, MRP uses Ethernet as its transport protocol. The well known Ethernet type for MRP traffic is 0x88e3.
Example traffic
XXX - Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot).
Wireshark
The MRP dissector is fully functional.
Preference Settings
There are no MRP 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.
Display Filter
A complete list of MRP display filter fields can be found in the display filter reference
Show only the MRP based traffic:
pn_mrp Capture Filter
You cannot directly filter MRP protocols while capturing. However, if you know the Ethernet type used (see above), you can filter on that one.
Capture only the MRP traffic over the ethernet type (0x88e3):
ether proto 0x88e3 External links

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