How to configure wireshark for dissecting LTE protocols:
How to configure wireshark for dissecting LTE/NR protocols:
- start the wireshark as a sudoers
- goto analyze->enabled prototols
=> enable mac_lte_udp and rlc_lte_udp
=> 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, 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
- 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
