sFLOW on OcNOS2

https://docs.ipinfusion.com/service-provider/index.html#page/OcNOS-SP/Sysman_Cmds/sFlowCmds.html#ww1025833

sFlow is based on sampling and is more scalable but provides less detailed information about individual packets,

whereas NetFlow tracks every packet and provides more detailed flow information, making it more suitable for in-depth analysis but potentially more resource-intensive.
