Thank you Ben for your reply.
Actually, I tried that (many times) but it didn't work. I tried :
sudo ovs-vsctl --no-wait set Open_vSwitch . other_config:flow_limit=1500
sudo ovs-appctl upcall/set-flow-limit 1500
but neither one has an impact on the number of flows cached by the kernel
datapath. This number is checked using the commands :
sudo ovs-appctl upcall/show
sudo ovs-dpctl dump-flows|wc -l
My Openvswitch version is 2.11.90.
Any other suggestions in this regards ?
