Hello,
I've configured a ProCurve 2910al to send sFlow data to my SolarWinds collector. For the most part everything is working fine except the switch starts sending data from ports I haven't selected.
For instance, on the SolarWinds NTA collector I've configured the port 48 as a NetFlow Source. On the switch I've configured sampling and polling on port 48. After The switch has run for a few minutes it starts sending data for other ports.
Here's some output from the switch. I deleted the sflow 1 configuration and then recreate it. After a couple of minutes you see that it's added port 47. Although not shown in this output, I've also tried setting ports 1-47 to 0 (disabled) - same result.
Any ideas?
Thanks.
