I want to enable Flow Control between a SAF Lumina and a CCR1036-12G-4S on SFP with Fiber SFP. But the autonegotiation for FlowControl does not work. Lumina status show flow control is off after negotiation. Found no status information on CCR. ROS is 6.15. I dont want to update without knowing this problem is fixed.

On Ethernetports of the CCR Flowcontrol autonegotiation works.

Anyone seen this? And knows if it is fixed in newer ROS-Releases.
