How to configure wireshark for dissecting LTE protocols:
- start the wireshark as a sudoers
- goto analyze->enabled prototols
- goto analyze->enabled prototols
=> enable mac_lte_udp and rlc_lte_udp
- goto edit/preferences and expand Protocols
- select UDP and check "try heuristic sub-dissectors first"
- select MAC-LTE, and check all the options (checkboxes), and set the "which layer info to show in info column" to "MAC info"
- select RLC-LTE, and check all the options except the "May see RLC headers only", and set the "call PDCP dissector for DRB PDUs" to "12-bit SN". Optionally you may select the sequence analysis for RLC AM/UM.

set the "call PDCP dissector for DRB PDUs" to "12-bit SN". Optionally you may select the sequence analysis for RLC AM/UM.
How to use
- start eNB or UE with option -W (or -P if you want to make a pcap file)
- capture on local interface "lo"
- filter out the ICMP/DNS/TCP messages (e.g. "!icmp && !dns && !tcp")
How to use
- start eNB or UE with option --opt.type wireshark
--opt options are:
--opt.type none/wireshark/pcap
--opt.ip 127.0.0.1 to specify the output IP address (default: 127.0.0.1)
output port is always: 9999 (to change it, change constant: PACKET_MAC_LTE_DEFAULT_UDP_PORT in OAI code)
--opt.path file_name to specify the file name (pcap)
- capture on local interface "lo"
- filter out the ICMP/DNS/TCP messages (e.g. "!icmp && !dns && !tcp")
