Hi everyone, We are observing strange OVS behavior in some of our setups.
Sometimes, the traffic just stops flowing through veth or tap interfaces plugged into OVS bridge.
ovs-appctl ofproto/trace for sample packet show that OVS will output it to the correct port, and we see real traffic in a mirror port we add to OVS.
This persists until one re-initializes the interface with ip link set down && ip link set up. Then the traffic flow restores. Nothing changes in OF flows as per ovs-ofctl dump-flows, except cookie value, which I presume means OVS re-installed the flows. The OVS database remains the same as well, except stats.
How can we debug this? I'm giving a high-level overview without any details as I'm not seeking for the solution, just a way to find one. I'm okay with OVS internals and diving into the kernel.
Many thanks, Valentine Sinitsyn _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
