Issue with Conversation OUT Report

Hi All,

we don't understand what we see with Conversation OUT Report with NetFlow Analyzer v. 9.5

we configured sFlow on switch HP Procurve as below:

sflow 1 destination X.X.X.X 9996

sflow 1 polling A1-A24,B1-B24,C1-C24,D1-D24 30

sflow 1 sampling A1-A24,B1-B24,C1-C24,D1-D24 500

On port A2 there is connect only one Server (we see only one mac-address); when we generate a Conversation IN Report and Group By Source IP we see only IP address (this is correct), but when we generate a Conversation OUT Report and Group by Destination IP we see more IP in addition Source IP.

Do you know if this Conversation OUT Report is correct?

Thank you.

Regards,

Marco
