[ovs-discuss] ovs flow duration

[Vinllen Chen]

Hi all:
    I build a small network to test the ping, the topology is showd below:

host1 ---- switch1----switch2 ----host2
host1 ip: 10.0.0.1
host2 ip: 10.0.0.2
    When i use host1 ping host2, and then use host2 ping host1, it works
ok. Then i use "ovs-ofctl dump-flows switch2" command to show the flows:
NXST_FLOW reply (xid=0x4):
 cookie=0x0, duration=1873.140s, table=0, n_packets=1843, n_bytes=180614,
idle_age=0, priority=1,ip,nw_dst=10.0.0.1 actions=output:1
 cookie=0x0, duration=118.427s, table=0, n_packets=118, n_bytes=11564,
idle_age=0, priority=1,ip,nw_dst=10.0.0.2
actions=mod_dl_dst:d3:97:e5:22:ea:ed,output:2
    The second flow will disappear when time duration arrival 120s. My
question is why doesn't the first flow disappear when time arrival 120s ?
    Thankyou for anyone's relay
Best wishes.
