Mikrotik traffic on disabled interface?

Question

Mikrotik

On Rb750 ROS 6.21 was updated to the latest versions - some time after the reboot, traffic appears (it can be seen on the interfaces tab) and quite significant, the microtic slows down, even the winbox freezes. After a reboot for a while - 15 minutes it works fine, then everything repeats. With what it can be connected? Where to dig? The rollback to 6.21 helped, but ...

Answer 1

The port is not bound to the master port.
the profile does not show anything, tk. with parasitic traffic, the winbox falls into a stupor, barely moves, only flying packets are visible. I had to roll back everything to 6.21 :(
