|

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
