Each flow entry is associated with zero or more actions that instruct the OpenFlow switch on how to handle matching packets. If no forward actions are present, the packet is dropped. Action lists must be processed in the specified order. However, there is no guaranteed packet output ordering within an individual port. For instance, two packets that are generated and destined to a single output port as part of the action processing may be arbitrarily reordered.
Pure OpenFlow switches support only the Required Actions, while hybrid OpenFlow switches may also support the NORMAL action. Either type of switches can also support the FLOOD action. The Required Actions are as follows:
- Forward: OpenFlow switches must support forwarding the ...
