The mikrotik uses spec 1.0 as referenced in their website http://wiki.mikrotik.com/wiki/Manual:OpenFlow. hmmm if you tell me that its normal then i dont have to worry then. Sorry for the stupid question but how do i configure port-mod openflow message ? is this done directly from the controller ?
What i'm trying to do is to bi-casting using floodlight controller. Therefore i need that the client which roams from AP1 to AP2 must be deleted from AP1 therefore it should not be shown as connected with AP1.
