Error to implement openflow in mikrotik

Hi everybody!

I want create a SDN network with OpenFlow, but I can’t configure the mikrotiks, the model is RB2011UAS-2HnD-IN with version of routerOS 6.5, with openflow. In other words, when I execute a command:
[admin@MikroTik] > /openflow add name=ofswitch1 controllers=1.1.1.1
then appears a message that say:
bad command name openflow (line 1 column 2)

My question is if anyone in this forum work with openflow, so what i should do for this work in this mikrotiks?

Thanks,

Currently RouterOS implements OpenFlow version 1.0.0 required features. Support for newer versions, optional features and switching hardware acceleration are to be added. Current implementation should be considered experimental - NOT production ready and is available for evaluation purposes. Please contact support with feature requests and bug reports.

OpenFlow support is available as standalone openflow package.
