How to configure wireshark for dissecting LTE/NR protocols:
|
|
- start the wireshark as a sudoers
|
|
- goto analyze->enabled prototols
|
|
=> enable mac_xxx_udp and rlc_xxx_udp (xxx is lte or nr)
|
|
- goto edit/preferences and expand Protocols
|
|
- select UDP and check "try heuristic sub-dissectors first"
|
|
- select MAC-LTE (or MAC-NR), and check all the options (checkboxes), and set the "which layer info to show in info column" to "MAC info"
|
|
- select RLC-LTE (or NR), 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.
|
|
- select PDCP-LTE (or NR)
|
|
|
|
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")
