When I revisited the old posts yesterday, I saw the post about the OMCI protocol
Does anyone know how to intercept "raw" OMCI messages on MA5671A to get something like this?
After processing, ONT-OLT flow of messages could be conveniently displayed in the Wireshark.

I made couple mistakes in my first attempts. The module stopped responding. Keep the backups and have the break-out board ready to revive the module.

OMCI daemon v7.5.1 (compiled on Oct 25 2016 17:15:59)
Usage: omcid [options]
Options:
-l, --log Specify log file
-o, --omcc Select OMCC version
-p, --config-path Specify custom config path
-c, --console Start console
-t, --trace-ioctl Trace onu driver ioctls
-d, --debug_level <number> Default debug level for all modules
(0 - max level .. 4 - no output)
-i, --iop-mask IOP option mask
-g, --lct-port Specify UNI index to be used as local debug port (1..4)
-m, --model Specify ONU layout model
-h, --help Print help (this message) and exit
-v, --version Print version information and exit
I tried with two levels of debugging.
