Hello, Currently wireshark decodes netflow v9 type=128 as "SRC_AS_PEER" and type=129 as "DST_AS_PEER". Does anyone know in which RFC or other documents they are defined? - from packet-netflow.c: |static const value_string v9_template_types[] = { |... | { 128, "SRC_AS_PEER" }, | { 129, "DST_AS_PEER" }, In RFC5102 (for IPFIX) id=128 is defined as "bgpNextAdjacentAsNumber" and id=129 as "bgpPrevAdjacentAsNumber". I think the former is equal to "DST_AS_PEER" and the latter is equal to "SRC_AS_PEER". I'd like to know whether this difference is a bug of wireshark or not. Regards,
A quick Google for <cisco netflow "source as peer"> shows 24 hits including the following: http://www.cisco.com/en/US/docs/ios/fnetflow/command/reference/fnf_02.html ---------- <snip> Router# show flow exporter export-ids netflow-v9 Export IDs used by fields in NetFlow-common export format: <snip> routing source as : 16 routing destination as : 17 routing source as peer : 129 routing destination as peer : 128 routing source traffic-index : 92 <snip> --------- I'm a newbie with respect to netflow so I don't know if the two messages are the same in v9 and IPFIX (v10) though I expect so. Further Googling may provide an answer. That being said: I could imagine displaying the correct name (depending upon the protocol version) if the v9/v10 names are different even if the v9/v10 semantics are the same for a type. (I'm currently reworking the netflow dissector to fix various bugs and to improve the protocol dissection/display but haven't been looking at the actual types). ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
