Inconsistent values of the Byte count and Packet count (GetFlowStats)

Dear all,

First of all, I am using a HP E3800 J9575A Switch and I want to catch the flow stats on my Datapath.

I will attach the Match that I am doing. But firstly I want to report some things and do some questions.

If I put my Flow mod message on table 100, and I do the "show openflow instance vlan10 flows" on my switch, the field of the Byte_count appears "NA". Altough on the controller interface, I can see some values on the byte count but they are inconsistent. Because sometimes I have 300 Packtes and 0 Byte_count or 70 Packets and 30 Byte_count, for example.

If I put my Flow mod message on table 200, and I do the "show openflow instance vlan10 flows" on my switch, the field of the Byte_count appears "0". And on the controller interface, packet_count and byte_count are zero too.

So, I want to know what are the differences between the table 100 (Hardware) and table 200 (Software) relatively of the Counters? And How I have too do my Actions toward my flows are on the correct table?

Thanks and Best regards,

João Tavares
