Hi You told about an explicit action called "userspace". What is the ovs-ofctl command option ? Is it the same ?

Any examples? Yes, there are a few. Setting an ARP field can only be done in userspace. > Is 'normal' action a user space only action? No, userspace figures out where the packet should go, but the pushes down kernel flows to do the forwarding. > If we have a set of actions to be performed, say a user space action then a > kernel space action , will they both be performed at the user space?

There's an explicit "userspace" action that acts like an output. Actions will be executed in the order that they're listed, but sending to userspace doesn't pause the processing after it. --Justin
