thanks , you're right , I can capture the changement  as following:

340483:2017-06-20T02:17:20.825Z|62030|vconn|DBG|unix: received: 
OFPT_FLOW_MOD (xid=0x2): ADD actions=NORMAL

but the ovs-vswitchd.log is filled with useless info  such as:

2017-06-20T02:21:31.658Z|63348|vconn|DBG|tcp:127.0.0.1:6633: received: 
OFPST_PORT_DESC request (OF1.3) (xid=0x61e993ec): port=ANY

      config:     0
      state:      0
      speed: 0 Mbps now, 0 Mbps max
  2(phy-provision): addr:26:40:cc:43:82:5d
      config:     0
      state:      0
      speed: 0 Mbps now, 0 Mbps max
  LOCAL(provision): addr:24:8a:07:55:41:e8
      config:     0
      state:      0
      speed: 0 Mbps now, 0 Mbps max

"tcp:127.0.0.1:6633" seems is a controller, I don't know what goodness 
after use it , do you know ?

how can I disable it ?
