7750 cflowd v9 bandwidth graphs by nfsen

[mwolff]

Hello,

I have a 7750 which is sending correct cflowd v9 data as per tcpdumps done at the nfsen server. But nfsen graphs are showing much more traffic than the real.
Flow active timeout is 1 minute and inactive timeout is 15 seconds. Traffic is IPv4 and IPv6 going in and out various vprn sap's. All of them are Nx100Gbps lag's.

Any experience with nfsen and cflowd will be highly appreciated.

Thanks!
Martin.
