    sFlow - ProCurve 2910al - Unwanted Ports

    gnomeAware

      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.
