Hi, I set idle_time_out = 0 and hard_time_out = 0 when I send flow-modify message to the controller. Then I dump the flows, got something like:
*** s4 ------------------------------------------------------------------------ NXST_FLOW reply (xid=0x4): cookie=0x0, duration=0.499s, table=0, n_packets=0, n_bytes=0, idle_age=0, priority=65535,arp,in_port=2,vlan_tci=0x0000,dl_src=ca:95:02:89:af:91,dl_dst=ae:ff:49:7b:43:37,arp_spa=10.0.0.1,arp_tpa=10.0.0.7,arp_op=1 actions=output:3 cookie=0x0, duration=0.39s, table=0, n_packets=0, n_bytes=0, idle_age=0, priority=65535,arp,in_port=3,vlan_tci=0x0000,dl_src=ae:ff:49:7b:43:37,dl_dst=ca:95:02:89:af:91,arp_spa=10.0.0.7,arp_tpa=10.0.0.1,arp_op=2 actions=output:2 cookie=0x0, duration=0.39s, table=0, n_packets=1, n_bytes=42, idle_age=0, priority=65535,arp,in_port=2,vlan_tci=0x0000,dl_src=ca:95:02:89:af:91,dl_dst=ae:ff:49:7b:43:37,arp_spa=10.0.0.1,arp_tpa=10.0.0.7,arp_op=2 actions=output:3 cookie=0x0, duration=0.501s, table=0, n_packets=1, n_bytes=42, idle_age=0, priority=65535,arp,in_port=3,vlan_tci=0x0000,dl_src=ae:ff:49:7b:43:37,dl_dst=ca:95:02:89:af:91,arp_spa=10.0.0.7,arp_tpa=10.0.0.1,arp_op=1 actions=output:2 But the flow still expired immediately. When I dump flows again, it showed nothing. Can someone tell me how to make flows permanent? Thank you. Bowei
