IEC61850 Edition 2-1 Sampled Value Message with Grandmaster (Clock) ID

Hello All

We are capturing a IEC61850 Sampled Values. The Sampled value from supported IEC61850 Edition 2.1 devices are carrying their GrandMaster ID (Synchronised Clock ID) in the capture. We can see the Grandmaster ID in the RAW data but I believe Wireshark still doesn't support this info to properly decode and display.

Is there any way Wireshark will consider to add this info to decade as part of Sampled values message from supported IEC61850 Edition 2.1 devices.

Also Is there any way I can decode this temporarily and display as a column?

There is no way to ad-hoc dissect a value not currently dissected, you need to modify the dissector, or maybe add fields with a lua post-dissector.

To get the existing dissector modified, please raise an enhancement request at the Wireshark Issues page and attach a capture file with the undissected traffic.
