Utilizing Smart Proxies

This is more of a general question rather than a problem, but I haven’t been able to find any documentation regarding this.

I’m testing Katello in our environment and I have a master Katello server. I’ve followed the instructions to sync a smart proxy and register it to my Katello server, but I have a few questions.

First, how can I tell my smart proxy is connected to the master? I don’t see anything listed under Infrastructure -> smart proxy. The only thing I see under ‘smart proxy’ menu on the GUI is the Katello Server itself.
Second, how do I register a client to the smart proxy? And… once my client(s) are registered to the smart proxy, can I manage them through the gui on the katello master?

Thanks much. Sorry I did not see documentation deep diving into this. If there is, please direct me towards it! Thank you again!
