Netflow collectors generally are passive with respect to receiving netflow only. They do not poll the devices; The devices export according to their export timing parameters which generally winds up producing a steady stream of UDP netflow packets to the collector.

I don't know what is the default sampling interval but we want to change it to something like every minute. Thanks David.

I don't believe it is. Are you doing this to reduce load / storage on your collector? David.
