How do I configure statistical packet-based sampling of packet flows with sFlow using CLI commands on my managed switch?

Configure the sFlow receiver (sFlow collector) IP address. In this example, sFlow samples will be sent to the destination address 192.168.10.2.

(Netgear Switch) (Config)# sflow receiver 1 ip 192.168.10.2
Configure the sFlow receiver timeout. Here sFlow samples will be sent to this receiver for the duration of 31536000 seconds. That is approximately 1 year.

(Netgear Switch) (Config)# sflow receiver 1 owner NetMonitor timeout 31536000
Here the default maxiumum satagram size is 1400. It can be modified to a value between 200 and 9116 using the command sflow receiver 1 maxdatagram <size>.
Configure the sampling port sFlow receiver index, sampling rate, and sampling maximum header size. You need to repeat these for all the ports to be sampled.

(Netgear Switch) (Config)# interface 1/0/1 (Netgear Switch) (Interface 1/0/1)# sflow sampler 1 (Netgear Switch) (Interface 1/0/1)# sflow sampler rate 1024 (Netgear Switch) (Interface 1/0/1)# sflow sampler maxheadersize 64
