Thanks for replying.

Yes, but I'd like to check on the ovs side after sending ID request.

for example,, controller_I'd=0, controller_I'd=1

where can I find such information? I thought ovsdb has it. But it is not shown by 'ovs-vsctl list controller'.

Every controller has controller ID zero by default, but a controller can
set its own ID on a per-connection basis using the NXT_CONTROLLER_ID
