Please be aware! Extreme XOS operating system before 15.4 release lack of support for ingress sFlow, only for egress. Please use 15.4 version or more recent.
Example of sFlow configuration for Extreme XOS:
configure sflow collector 10.0.2.33 port 6343 vr "VR-Default" # add collector configure sflow agent 10.0.2.15 # agent address configure sflow poll-interval 1 # send data to collector once per second configure sflow sample-rate 1024 # sampling rate enable sflow ports 1:39,1:40,2:39 both # add ports to sFLOW monitoring for egress and ingress traffic. enable sflow # enable sflow globally
Check configuration for correctness:
show sflow
