[ovs-discuss] How to get ovs listen port?

[can.]

I may not make my question clear.

My problem is that the controller does not support some features of ovs, so
as a circumvent, I tried to get the port number and remotely control the
switch using ovs-ofctl. This trick must parallel the common scenario, say,
the controller doesn't know which switch will connect to it. So the
switch's port number could not be pre-configured and might not be the
default one. In this scenario, is there a way to fetch the port number?
