I am experiencing this issue when sampling on an interface which is a member of a VRRP instance on a HP PROCURVE 5412ZL.
With traffic coming in on interface A and leaving on interface B, where B is part of the VRRP instance, the output interface written in the flow samples is this: sflow.fs.ifindexout == 0x3fffffff Which according to the specification indicates that there is no output interface. The same behaviour applies in the other direction, where traffic is incoming on interface B and leaving on interface C (which is not a VRRP member). I was wondering if anyone experienced any similar issues before I report this to HP. --- Cheers, Rune V. Sjoen You always pass failure on the way to success
