Hello, When using Wireshark, have you tried a right-click on flows supposed to be IPFIX and select the option "Decode As". You'll have a list of protocols that Wireshark is able to decode. Select CFLOW decoder and see if it still cannot detect IPFIX flows. Try to update Wirehark to the new version if it is not working.
About your Nortel troubles, I can't help as I'm not using them.
have a good day

[Ntop] Ntop and Avaya/Nortel IPFIX

Hello,
I am currently working on a project involving LAN traffic monitoring using
our Nortel Switches (ERS5000 and 4500). I noticed that when using Ntop as
the Netflow collector, the amount (in size) of traffic seen by Ntop is
nothing near reality… (I am also testing a commercial product which seems
to work fine while yet another commercial product gives me the same
information as Ntop..). Is something wrong with Nortel’s IPFIX
implementation? Wireshark is not able to understant the IPFIX messages, but
I do not know if there is an IPFIX dissector embedeed in Wireshark and if
it is able to see the IPFIX template in the capture and use it…
Thanks in advance for your help,
Regards
