I want to use DLT-user to decode RLC-NR data, but failed. It says 'can't dessect NR RLC frame because no per-frame info was attached. I know some parameters like sn length, am/um, but how can this info be told to wireshark?
Hi, you need to use the UDP framing protocol described here so as to provide the dissector all the per-frame info. It measn that you cannot use a DLT user for this decoding.
Can you share an example? Where should this infor attached? Before or after the frame?
The framing is explained in the header file link I shared, which should be self explanatory. Do you have any specific question after reading it?
Sorry, i can not make it. Do i need to make a UDP head? if 'rlc_nr' is placed as a UDP payload, it is not decoded as rlc, If no UDP head exist, 'rlc-nr' is decoded to udp ports.
The framing protocol should be in the UDP payload. You must also activate the rlc_nr_udp heuristic dissector in the Analyze -> Enabled Protocols windows. Maybe that's what is missing here.
