https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=2944 Summary: LLC GPRS - "Unnumbered Information" should be "Unconfirmed Information" Product: Wireshark Version: 1.0.3 Platform: PC OS/Version: Windows 2000 Status: NEW Severity: Minor Priority: Low Component: Wireshark AssignedTo: wireshark-bugs <at> wireshark.org ReportedBy: khaithye <at> yahoo.com.sg Created an attachment (id=2322) --> (https://bugs.wireshark.org/bugzilla/attachment.cgi?id=2322) Example of a GPRS LLC UI frame Build Information: Shark 1.0.3 (SVN Rev 26134) Copyright 1998-2008 Gerald Combs <gerald <at> wireshark.org> and contributors. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. Compiled with GLib 2.14.6, with WinPcap (version unknown), with libz 1.2.3, without POSIX capabilities, with libpcre 7.0, with SMI 0.4.8, with ADNS, with Lua 5.1, with GnuTLS 2.3.8, with Gcrypt 1.4.1, with MIT Kerberos. Running on Windows 2000 Service Pack 4, build 2195, with WinPcap version 4.0.2 (packet.dll version 4.0.0.1040), based on libpcap version 0.9.5. Built using Microsoft Visual C++ 6.0 build 8804 -- In the decoding of GPRS LLC layer, the UI format is erroneously decoded as "Unnumbered Information", but according to ETSI 04.64, it should be "Unconfirmed Information". The term "unnumbered" is misleading, because there is an N(U) in this layer for UI format (so, it's actually numbered). Following is an example: MS-SGSN LLC (Mobile Station - Serving GPRS Support Node Logical Link Control) SAPI: GPRS Mobility Management FCS: 0x21c14e (correct) Address field SAPI: LLGMM 0... .... = Protocol Discriminator_bit: OK .0.. .... = Command/Response bit: DownLink/UpLink = Response/Command .... 0001 = SAPI: GPRS Mobility Management (1) Unnumbered Information format - UI, N(U) = 0 110. .... .... .... = UI format: 0x0006 ...0 0... .... .... = Spare bits: 0x0000 .... .000 0000 00.. = N(U): 0 .... .... .... ..0. = E bit: non encrypted frame .... .... .... ...1 = PM bit: FCS covers the frame header and information fields -- -- Configure bugmail: https://bugs.wireshark.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
