[ovs-discuss] Changing number of flow tables in open vswitch

[Paulose Saumya]

As you said I checked the controller and found that the controller won't support the switch because it has 256 tables. It supports only less number of tables. So is there any possibility to customize the number of tables by specifying low value for number of tables ? Or is it the number of tables is fixed and cannot be changed ?

Regards,
Saumya

I assume the command line utility that you're using is "ovs-ofctl dump-flows".  If that's the case, it's just using OpenFlow over a local socket.  Since your controller is likely using OpenFlow, too, it might be worth looking at your controller.
