Hello, Please can you help with this short question: Is the unique flow identifier (ufid) persistent ? i.e. flow-a is in dp-cache with ufid = 1000, then the flow is evicted from dp-cache , and after 5 minutes the same flow-a is reinstalled in dp-cache. The question - is flow-a is being assigned ufid = 1000 again ? Best Regards avi
