But, if you are using the supported UDP framing format, you may be able to filter on the UDP port you know that you are using, e.g. You cannot directly filter MAC-LTE protocol frames while capturing.
Show only the MAC-LTE based traffic: mac-lte Capture Filter Keep this file short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.Ī complete list of MAC-LTE display filter fields can be found in the display filter reference XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Looks for and shows links between SR request and resulting grant or failure indication. Default is TRUE.īSR size when warning should be issued. When frame marked as reTx, looks for link back to original tx. Can configure data channel ID and RLC mode so that RLC-LTE dissector can be called for these SDUs.Īttempt to track UL HARQ resends. Starting from Wireshark 2.0, heuristic activation is moved to Enabled Protocols window.Īttempt to dissect LCID 1&2 as srb 1&2. Default is TRUE.ĭissect frames that have failed CRC check. Default is 3.Īttempt to decode BCH, PCH and CCCH data using LTE RRC dissector. Number of Re-Transmits before expert warning triggered. The same statistics can be viewed in tshark using the -zmac-lte,stats option.
MAC-LTE statistics can be viewed in a window (see Telephony The functions get_mac_lte_proto_data() and set_mac_lte_proto_data() are available for querying and setting the necessary context information associated with a frame. Currently, this does not have its own registered DLT, so if (as the same program does) you use DLT 147 you will need to edit the preferences of the DLT_USER dissector (add an entry with DLT=147, Payload Protocol=mac-lte-framed) OR This (BSD-licensed) program gives an example of how you might write MAC-LTE frames directly in a file of this format. This shares the same framing format as the UDP format described above. The compact format decoded by the mac-lte-framed dissector.
This (BSD-licensed) program gives an example of how you might send MAC-LTE frames in this format OR Using the UDP format defined in packet-mac-lte.h. There is support for reading MAC-LTE frames from: The MAC-LTE dissector is fully functional. RAR UL Grant field can be broken down according to 3GPP TS 36.213 Protocol dependenciesĪ UDP framing format for MAC-LTE has been defined (described in packet-mac-lte.h, purely for use with Wireshark)Ĭan call RLC dissector for its SDUs (see Preference Settings below)īCH, PCH and CCCH payloads can be decoded by the LTE RRC dissector This protocol is layer 2 of the LTE air interface (connecting an LTE UE with an eNodeB).
