Hi Iwase,
Sorry for the late answer
well... I checked the group stats as you said and it's not being looked up
*ovs-ofctl dump-group-stats -O OpenFlow s2*
*OFPST_GROUP reply (OF1.3) (xid=0x2):*
*group_id=1,duration=12.837s,ref_count=0,packet_count=0,byte_count=0,bucket0:packet_count=0,byte_count=0,byte_count=0,bucket1:packet_count=0,byte_count=0*
I'm really lost and don't know how to fix that
Do you have any idea of how can I solve this problem?
many thanks.
