Yes, that's how it currently works. Roaming in Linux is not very
advanced, yet. We are working on it, but I assume it will take another
year before we get significantly faster roaming.

Currently there is no way to do it. For the last couple of years we
have talked about this, but the progress has been slow because various
components are involved here. See some discussion here:

I don't know what settings the cisco controller has, but currently in
Linux all control is in client side.
