About NetFlow Packet Sampling
The NetFlow-lite feature is based on ingress packet sampling at a monitoring point that can be an
interface on the switch. By exporting NetFlow sampled packets, it provides visibility into traffic that is
switched through the device. The rate at which input packets are sampled is configurable and a wide
range of sampling rates are supported. The sampled packets can be exported with NetFlow V9 or IPFIX
format.
