[ovs-discuss] Connectivity between openvswitch and floodlight controller on two different VMs

[Vikram Khatri]

I guess the problem may be I am not defining controller out-of-band, since controller is on other VM.

I tried using command: ovs-vsctl set-controller br1 connection-mode=out-of-band , but it didn't work.

Later on, I found controller ID and used ovs-vsctl set-controller _uuid connection_mode=out-of-band, and the connection became out of band but no improvement yet.

I can see from the ovs-vsctl list controller command: status: {last_error="No route to host", sec_since_disconnect="2",state=BACKOFF}

The route is defined ....... they can ping each other may be something else.

Hi Justin,

Thanks for clarification. I didn't know that ovs-controller is itself a controller, and used that command.

I want to use floodlight controller to connect with openvswitch. Can you share about their config connectivity i.e. how would openvswitch connect with controller (other than ovs-controller).

ovs-controller and Floodlight are two different OpenFlow controllers.  I didn't see any references to ovs-controller until the error message you showed at the end.  It appears to me it wasn't invoked properly and didn't have "ptcp:" or something similar as an argument.  However, it's not clear from your message that you really intended to run ovs-controller.
