Hi,

A UE is receiving a BCCH-BCH message that encapsulates a MIB. Are you sure we need to expose the MIB dissector directly?

Best regards,

Pascal.

Hi,

The NR-RRC messages has to be dissected by calling dissector by name. Currently “MIB” is not handled but I have amended the code to expose it.

Instead of building a UDP packet with the MIB Octets as data you can create an “Exported PDU” by using text2pcap

text2pcap.exe -l 252 MIB.txt mib.pcapng

 

The code change can be followed here https://code.wireshark.org/review/#/c/34852/

Dissection result:

Regards

Anders

No In wireshark there is no such seperate NR RRC over UDP option. But then if not UDP then how am I supposed to send and receive packet ?

What is the payload of that UDP packet supposed to be?

Is there some "NR RRC over UDP protocol" being used?
