Subject: Re: [Wireshark-users] Query regarding GSM MAP traces analysis
> Dear All
> I have collected some SIGTRAN traces between (R11 GSM MAP) with Wireshark 0.99.7 (Windows).
> All protocols have been enabled, however when analyzing the packets, Wireshark disects and displays packet details/attributes till SCCP layer (i.e. IP, SCTP, M3UA and SCCP).
> All SCCP User Data (e.g. MAP) however is just shown as "Data". SCCP Message Type is UnitData (0x09), Class is 0x01.

To decode gsm MAP protocols, define all the SubSystem Numbers reserved for MAP (SSN) :
Select menu : Edit / Preferences
Click on "Protocols"
Scroll down to "GSM_MAP"
Fill "TCAP SSNs" textfield (like :5,6,7,8,9,10,12,147)
Finished ? "APPLY/OK"
Alain.
