端口6634是ovs-vswitchd監聽端口是被動連接管理的端口 所謂的被動連接端口是指，控制器可以主動連接此端口，控制此ovs，下面就是設置被動端口的 方式 ovs-vsctl set-controller s1 ptcp:8888 特別說明：相對應被動端口，主動端口（ovs主動連接並和控制器通信的端口）設置方式如下: ovs-vsctl set-controller s1 tcp:127.0.0.1:8887 主動連接本地控制器127.0.0.1:8887端口 主動連接也可以設置多個，設置方法如下 通過通信數據包得知，該ovs會和本地控制器6636和6637通信，如果有packet in事件時候會將該事件分別發一份給這兩個控制器，至於兩個控制器間的關系協作暫無研究。 ovs-vsctl set-controller s1 tcp:127.0.0.1:6636 tcp:127.0.0.1:6637
