(Strictly speaking, these are all amendments to the original 802.11 standard, but they are also de facto standards in their own right.) Like classic Ethernet, Wi-Fi must deal with collisions unlike Ethernet, however, Wi-Fi is unable to detect collisions in progress, complicating the backoff and retransmission algorithms. Wi-Fi is a trademark of the Wi-Fi Alliance denoting any of several IEEE wireless-networking protocols in the 802.11 family, specifically 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac and 802.11ax. Register_dissector("2", dissect_mac_fdd_edch_type2, proto_umts_mac) Register_dissector("", dissect_mac_fdd_edch, proto_umts_mac) Register_dissector("", dissect_mac_fdd_dch, proto_umts_mac) Register_dissector("", dissect_mac_fdd_pch, proto_umts_mac) Register_dissector("", dissect_mac_fdd_fach, proto_umts_mac) Register_dissector("", dissect_mac_fdd_rach, proto_umts_mac) $ grep register_dissector packet-umts_mac.c Packet-umts_mac.c: proto_umts_mac = proto_register_protocol("MAC", "MAC", "mac") $ grep "proto_register_protocol" packet-*.c | grep "\"MAC\"" In this case, it seems you need to look at the source code (unless there's some other method I'm not aware of) in order to find the dissector that's actually registered.

So in the case of RSL, it looks like you'd need Dissector.get("gsm_abis_rsl"):call(buf, pinfo,tree) Radio Signalling Link (RSL) RSL gsm_abis_rsl (Refer to the tshark man page for more details on the -G option.)įor example: $ tshark -G protocols | grep RSL If you're looking for the correct protocol names, you can try running something like tshark -G protocols | grep NAME … where NAME is the name of the protocol you're looking for.
Below is the answer I provided to this same question over at, but copied here for convenience:
