WDS security

Hi to all,
I would an information about WDS security…

I have router A and router B in static wds mode…
I use for A e B the same security profile. But I viewed that if I use different security profile the link is always on.
Why? the security profile haven’t effect in wds mode ? If yes in which way is it possible securize a wws link?

The link is “connected” but no traffic..

I don’t know why, but works like this.

Can you post your config and tell us if there is traffic?
