Hi, Thanks a lot for quick answer. I have now upgraded ovs to the latest version and gre tunnels are working fine. However, there is still one unsolved issue:
When connection from ovs to NOX openflow controller is made, ovs sends continuously error messages approximately once per second in the following way: NOX->OVS: vendor (SM) OVS->NOX: Error (SM) NOX->OVS: Flow Mod (CSM) OVS->NOX: Error (SM) OVS->NOX: Error (SM) OVS->NOX: Error (SM) OVS->NOX: Error (SM) OVS->NOX: Error (SM) ... Is there any way to suppress these messages? The error type is unknown (45250) and error code 0.
