No. As mentioned, the SUP plays no part in this really. The client downloads the catalog/metadata from WSUS in response to many different things including new deployments, the software update scan cycle, and even all by itself if you haven’t disabled automatic updates.

My understanding is that clients process the catalog’s meta-data and then retrieve only the software updates that apply.

The client retrieve the update catalog directly from WSUS. They cache the catalog and generally only download deltas when needed. I don’t know all of the cases where a full download is required but a WSUS change is certainly one and Microsoft mucking with the catalog too much is another one (as they’ve done this multiple times in the past in turn causing lots of network traffic and pain).

Configuration Manager clients will get software updates metadata many times (scan scheduled, deployment, after a deployment...). The question would be: Once the SUP Server has finished synchronizing with Windows Update, it will modify its catalog version and ask the clients for a scan (therefore a catalog download). Is this catalog download only a delta or a full download? And in which case the catalog would be fully downloaded on clients ? (except when their assigned SUP is not the same as last catalog download) Thanks. Jérémy.
