Tried NetFlow v5 and v9 and in both cases when I show the vlan interface stat on the switch, it would tell me say:

"input rate 87.95 Mbps, 7.96 Kpps; output rate 3.32 Mbps, 4.22 Kpps" for 5 min, but the Analyzer say "In Avg 312.4 Kbps, Out Avg 8.22Kbps" for the same 5 min.

No sampling configured on the Nexus.

Any ideas?

Thanks!
