Hi, I am trying to use MAC-LTE packet dissector on the eNodeB side. Currently I am finding difficulty in using it. I have gone through many of your support site but things are not looking good at my side. This is what I have tried. 1. I do not have any catapult DCT2000. Hence I can not capture files in .out format. 2. I am using UDP packets to carry MAC-LTE frames.
OK, did you check the MAC-LTE protocol preference 'Try Heuristic MAC-LTE over UDP framing"?
3. As I can not decode the packets, I have added handler to get the option for " Decode As" inside proto_reg_handoff_mac_lte() function. With this I am able to find the "Decode As" option for MAC-LTE. But whence i try to decode, I am thrownwith following error: "Can't dissect LTE MAC frame because no per-frame info was attached!"
The heuristic dissector parses the header, populates a struct with the given info and attaches it to the frame (for mac-lte). If the heuristic dissector didn't match the frame, p_get_proto_data won't contain a filled-in struct.
Can you please help me, as why "p_get_proto_data" is throwing error. 4. Currently to bring up the setup, I am using the sample program "mac_lte_logger.c" file given at wireshark site to generate the packets. Can you please also let me know any list where I can paste, it might be helpful for others too.
If you've tried the preference setting I mentioned above and its still not working, could you send me the captured file and I'll see what is going wrong with it? Regards, Martin
