Default flow entries are not specified in the OpenFlow protocol. The Zodiac FX does not create any default flows when the Zodiac FX starts up.

When no flow entries exist, behaviour differs from OpenFlow v1.0 and v1.3.

In OpenFlow v1.0, packets are sent to the controller.

In OpenFlow v1.3, packets are dropped (discarded). Note that this behaviour may be overrided by your controller.
