Selecting a suitable packet sampling rate is an important part of configuring sFlow on a network device. The table below shows recommended values for sampling rates in regards to the link speed.

Link speedSampling rate
10 Mbps1 in 200
100 Mbps1 in 500
1 Gbps1 in 1000
10 Gbps1 in 2000
If traffic levels are unusually high the sampling rate may be decreased (e.g. use 1 in 5000 instead of 1 in 2000 for 10 Gbps links).
