loosing connection to AP -> keepalive

Hi

I have a problem with my CAP AccessPoints.
If I connect tem direct to my router (RB3011) all works fine.
But now I have to deploy that wireless setup to its destination and connect the AP’s to a Switch.

As soon as I connect the APs to the switch the connection gets unstable.
The AP disappears and come back after a few seconds. This repeats in a endless loop.

The Log Tells:

Is this a switch fault? Or a configuration fault?
I’m sure it’s related to the switch because a direct connection works fine.
