Hello, I have dissected exported pdu successfully over udp. but I need to dissect it over ethDev. sctp and gtp is it possible? . because same heuristics I am using to dissect, but it is not working. Can we form exported pdu only over UDP ?
The exported PDU format is NOT over UDP, as seen in the pcap I shared previously. It's an encapsulation type that does not run over any transport protocols. It's a mechanism allowing to call any dissector without the need to have an encapsulation in lower layer packets. The MAC-NR heuristic dissector can also run over UDP, as explained in https://code.wireshark.org/review/gitweb?p=wireshark.git;a=blob;f=epan/dissectors/packet-mac-nr.h;hb=refs/heads/master. It does not run over over protocols. Best regards, Pascal.

Help me regarding this issue. please find attachment.I already explained you what was wrong in https://www.wireshark.org/lists/wireshark-users/202002/msg00007.html and https://www.wireshark.org/lists/wireshark-users/202002/msg00009.html. See the attached pcap for an example that should help you getting autonomous. Ensure that the mac_nr_udp heuristic dissector is activated (Analyze -> Enabled Protocols -> check mac_nr_udp box).
