Hi,
i have tried to upgrade my RB4011 from 6.48.6 to 7.2.1 or 7.1.5 and after the upgrade my RB4011 loose the connection with my one of my Mikrotik Sw RB260GS.
I am using 2 x RB260GS on ether 9 and 10. The one on ether 10 is loosing the connection and reconnect for a couple of seconds. Kind of a loop connection and reconnecting. The other on ether 9 works fine. After downgrade to 6.48.6 everything works fine but v7 dont work.
I hope you can help me out with this strange issue :/
