Parameters
determine: Specifies the fixed sampling mode. For example, if the flow sampling interval is set to 4000
(by using the sflow sampling-rate command), the device samples packets as follows:
• The device randomly samples a packet, like the tenth packet, from the first 4000 packets.
• The next time the device samples the 4010th packet, and so on.
random: Specifies the random sampling mode. For example, if the packet sampling interval is set to
4000, the device samples packets randomly as follows:
• The device might sample one packet from the first 4000 packets.
• The device might sample multiple packets from the next 4000 packets.
• The device might sample no packets from the third 4000 packets.
However, the device samples one packet from 4000 packets on average.

Use sflow sampling-rate to enable flow sampling and specify the number of packets out of which flow
sampling will sample a packet on an interface.
Use undo sflow sampling-rate to restore the default.

Parameters
rate: Specifies the number of packets out of which flow sampling will sample a packet on the interface.
The value range for this argument is 1000 to 5000.
