WDS WAX610Y and WAC564

Hello,
I have set up the WAX610Y as the base Staion AP and WDS.

Unfortunately, my WAC564 with the same WDS settings does not connect to the wireless bridge.

The STP is enabled on both devices.
On the WAX610Y I have entered the Local MAC Address of the WAC564 as the Remote MAC Address and on the WAC564 I have entered the Remote MAC Address of the WAX610Y.

As Authentication I have taken OPEN for the time being.

Unfortunately no connection is established.

Does anyone have any tips for me?
