Do we have a way to identofy the Netflow Version Automatically, when we read using nfdump?

[tarungoswami]

Is there a way I can read Netflow Version Automatically, when we read using nfdump? Its anyway available as part of detail sent by the router

Can you elaborate your needs here? When reading netflow with nfcapd it's automatically read, regardless the version. The version is not store in the nfdump file.

Hello Peter, Since I have multiple routers, some sending on v5, some on v9 and some on v10/IPFIX, I need to know on what versions the routers are sending the data. So can you include the version number as part of the nfdump data?

Thanks for your quick turnaround. Can you please help me with how exactly will we get the netflow version via nfdump. I mean which command, options

[phaag]

You do not need anything. When collecting flow data it's added by default. Make sure to start the new collector. Check your flows with -o raw for example, you see the netflow version at the top. For other output formats and for filtering, see nfdump(1)
