Dear ovs-dev, I'm trying to see if I can increase the number of flows supported in kernel cache. I found two relevant config options (other_config:flow-limit and upcall/flow limit). My understanding was that other_config:flow-limit is for the normal openflow flows while upcall is for the kernel flows (http://docs.openvswitch.org/en/latest/faq/design/ question one). It seems I can change the limit for Openflow flows. This works: $ovs-vsctl --no-wait set Open_vSwitch . other_config:flow-limit=200001 $ovs-vsctl --no-wait get Open_vSwitch . other_config:flow-limit "200001" However I cannot change the limit for kernel flows. This does not: $ovs-appctl upcall/set-flow-limit 200001 set flow_limit to 200001 $ovs-appctl upcall/show system@ovs-system: flows : (current 70) (avg 68) (max 92) (limit 200000) dump duration : 3ms ufid enabled : true 127: (keys 3) ... My question is, is it possible to change the limit on kernel flows
I don't know of any way to do that. - Greg _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
