Hi Tanachart,
I don't see you need to set such of Rule Criteria. Can you just set the 2 interface models, i.e. ifIndex = 1 and 2, into Correlation Domain (don't involve other interface models)?
If only those 2 interfaces in the Correlation Domain then you will need that Rule Criteria.
And I would recommend start from one symptom condition and test if the Correlation works. And you can gradually add more symptom conditions and test further.
