Sflow Sampling-Rate - HP MSR1003-8S Command Reference Manual

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.
