Load balance on CMTS Cisco 10k

Hi for everyone, I want to prove load balance in CMTS 10k with DOCSIS 3.0 and watch the balance in the differents bonding group of downstream but I don't know what can I do, so if everyone know some process or tests for to show this, I really appreciate...

At the first time, I conect the CMTS to 4 laptops and a server. The server send a 5 MB in a 1GB link. I wanted to saturate the link and see if the other cable modems were connected to other carriers, but I did not throw any data.
