Hi Fujimoto san,
Thank you very much for the code. I have ran it and it was working. Thanks,
you have saved my days.
Btw, I have another questions related to this issue. I do hope you will not
mind :)
a. When I am trying to add port and add/delete bridge, I did not find any
function related to those commands in library bridge.py. Is it mean I can't
add port using library bridge.py?
b. I saw in library vsctl.py, there is some commands related to add port
and add/delete bridge. Is it mean we must use this library to add the port?
Thank you for your help.
regards,
deni
