I am using wireshark version 1.11.0. I am facing problem while decoding the Triggering-Events IE sent in Create Session Request in GTPv2 protocol. The size of the decoded IE by Wireshark is 8 bytes long but as per specification-32.422-ab0 the size should be 9 bytes long. Can any one have a look and please let me know. Hope for your cooperation. Thanks in advance. -- Regards Mrinal Aich Software Engineer-1, Dynamic Digital Technology, Kolkata asked 18 Nov '13, 23:46  Mrinal edited 20 Nov '13, 03:27 |
One Answer:
Section 8.31 of 3GPP TS 29.274 is where the GTPv2 IE specifically is defined. Mrinal is correct, it's defined as a nine byte field. My C is rusty but I believe the problem is line 2411 of file epan/dissectors/gtpv2.c in Wireshark's source code. Looks like it defines that IE as 8 bytes (that "8" is there the byte length is given for the other IEs as you go along): It also misspells "triggering", at least in the source for Wireshark 1.10.2. Mrinal, I recommend posting this issue as a bug at: https://bugs.wireshark.org/bugzilla/ answered 20 Nov '13, 18:14  Quadratic edited 20 Nov '13, 18:25 |
I can't find any "Triggering-Events" ary you talking about a Diameter message with an AVP "Triggering-Events"? If so what vendor id and what AVP number? If not which protocol, protocol messge and IE are you refering to? A bug report with a trace file is an alternative :-)
