Yes, I was using older version of packet-mac-lte.h. I had redefined as it was not defined there. The old version had ID.

With the new .h file it is working. Thanks a lot for your quick help.

I see in your file that the PDUs logged don't have the "mac-lte" prefix.
You redefined MAC_LTE_START_STRING to be "" in the logger program... Isn't it supposed to #include "pack
et-mac-lte.h"?
The definitions used in that program need to match wireshark, otherwise the header inside the UDP frame won't be dissected correctly...

Hi Martin,
Thanks for the quick response. I have enabled heuristic MAC-LTE over UDP framing, as you have already mentioned in one of the previous list emails. under edit->preference->protocol->mac-lte. I am hereby attaching the pcap file, which I am trying to decode. Please let me know, if anything is missing.
I am using wireshark version 1.3.5.
Regards,

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
