Right, but in this case it’s very important to make a distinction between SUP and WSUS as SUP means something ConfigMgr centric which the catalog update process has nothing to do with really.

The behavior we’ve seen is that during last Patch Tuesday, the WSUS/SUP started a synchronization and once finished it launched a request on every single machine of the site and tell them to start a Software Update Scan. (https://technet.microsoft.com/en-us/library/bb632485.aspx see Synchronization Process) 7000 clients on the same network hitting a primary server to get the catalog and send their scan was an overload we couldn’t plan. And I didn’t see any corrections on ConfigMgr 2012 to say that Microsoft worked on that issue. Jérémy.

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.
