Hi,

The dissector decoding NAS EPS messages are in epan/dissectors/packet-nas_eps.c it's written in C so there's

no dictionary nor definition of NAS messages.

 

You could probably arrange to call the dissector trough one of the USER_DLT:s depending on the format of your file.

Subject: [Wireshark-users] NAS/S1AP traces and wireshark definitions

Hi all

Does someone have some S1AP traces for the messages: 
Initial UE message, Initial Context Setup Request, UL NAS Transports? I have 
NAS-EMM and NAS-ESM packets, but cannot decode this NAS packet without the 
appropriate S1AP packets. The underlying SCTP is no problem to generate. 

Could someone give me a hint where I can find the dictionary or a 
definition of the NAS packets in the wireshark? How the values of the fields are 
interpret?

Thank you in advance for your help.
Best 
regards
James
