In Wireshark, you must ensure that the following options are checked:

  • Edit -> Preferences -> Protocols -> UDP -> Try heuristic sub-dissectors first
  • Edit -> Preferences -> Protocols -> RLC-LTE -> Try heuristic LTE-RLC over UDP framing

Hi Pascal,

Thank you for your reply.

I want to know in which directory in the wireshark I can run that sample rlc-lte logger program which is available in RLC-LTE wiki.

Thanks, Sathish

The sample program is completely independent of Wireshark. It opens a UDP socket towards the IP address and port given as argument, and sends 3 hardcoded PDUs. It can be run from whatever place you want.

Hi Pascal,

Thank you for your reply.

I want to know how to check 3 hardcoded RLC-LTE PDUs in wireshark. whether it shows like UDP PROTOCOL or RLC-LTE PROTOCOL.

You need to capture on the interface corresponding to the address you give as parameter to the rlc_lte_logger program (that you compiled yourself- see the source code for details) and configure Wireshark per my first answer. If everything is configured properly, it will appear as RLC-LTE.

To compile the program, by default it expects to be in a folder next to wireshark source code:

include "../wireshark/epan/dissectors/packet-rlc-lte.h"

You can modify this line according to your needs.
