Hi Amit,

the strange thing is that 65MB is exactly five times 13MB. Which
sampling rate are you using? How things change by playing around
the sfacctd_renormalize option? Is it possible the data flow is
being over-estimated because, say, it's traversing multiple sFlow-
enabled switches or because it's routed and passes through the
same switch multiple times, maybe in different VLANs? Lastly,
can you also say which direction is the sFlow agent sampling
traffic (incoming or outgoing)? 

Cheers,
Paolo
