OpenFlow instance mode
OpenFlow can work either in active
or passive
mode.
Active mode
New packets of a flow that the switch is not aware of are sent to the OpenFlow controller.
Passive mode
- There is one-way communication from the OpenFlow controller to the switch. Packets that do not match any flow in the flow table on the switch are not sent to the controller. The switch normally handles such packets of new flows.NOTE:
This option is applicable only for an OpenFlow version 1.0 instance.
This command sets operation mode for an OpenFlow instance.
