and In the logical_switches section look for dpid thatdpids that you just have noted and note the switch Id corresponds both DIPDS, you will see something like,

In my case switch Id that correspond to DPID "00:00:ff:ff:ff:ff:ff:05" is "7" and DPID ,"00:00:ff:ff:ff:ff:ff:07" correspond to switch Id "2". Note switch Id of both the switches. Now in the same file there is section for optical_links,

{optical_links, [{{2,20},{4,30}}, {{2,30},{5,50}}, {{3,30},{4,50}}, {{4,20},{1,50}}, {{5,20},{1,20}}, {{6,20},{3,50}}, {{6,50},{8,50}}, {{7,40},{2,50}}, {{7,30},{3,40}}, {{8,20},{3,20}}, {{9,20},{7,50}}, {{9,50},{10,30}}, {{10,50},{6,30}}, {{10,20},{7,20}}]},

In the above list show all the optical links. {{7,40},{2,50}}, means switch_Id 7 port 40 is connected to switch_Id 2 port 50. You need find the link port then you want to bring down. In my case its switch 7 port 40.
