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 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 might sample one packet from the first 4000 packets, multiple packets from the next
4000 packets, and none from the third 4000 packets, randomly. Generally, the device samples one
packet from 4000 packets on the average. The random sampling mode is not supported in the current
software version. This keyword is reserved for future support.

# Specify fixed flow sampling mode on GigabitEthernet 3/0/1.
