Hi Sir/Ma'am,

This is Simran Kumawat, Project Associate at 5G-TestBed Project, IIT Hyderabad.
I am working on the F1AP interface currently, I observed a few things as mentioned below.
Wireshark is dissecting f1ap msgs like this -
1. Initiating Message ----------------------> Initiating Message
2. SuccessfulOutcome Message--------> Initiating Message
3. UnsuccessfulOutcome Message-----> SuccessfulOutcome Message
The information contained is also the same but the problem is  only at this moment. for example ,

wireshark is dissecting F1SetupResponse ------------> F1SetupRequest and  

                                      F1SetupFailure----------------> F1SetupResponse
with the same content. There is no problem in the code because after decoding at receiver side, I am printing the info contained in the packet.
I am attaching the wireshark capture for your reference and logs from sender and receiver side.

I request you to please check with the issue mentioned above.
In case of any query, please get back to me.

Thanks and Regards,
Simran Kumawat
Project Associate, 5G-TestBed
