sm bandwidth control

I re-created the scenario on Canopy userguide 8 page 97 (description) and 98 the diagram.

I provisioned in prizm a 5.2 sm with 5mb, that sm is passing the gps sync to a 5750 ap through the sync cable. In addition, I have a 5700 sm that is getting registered to that 5750 ap and has Internet. My problem is how to control the bandiwidth on the sm units, so far running a bandwidth test gives me the 5mb on the sm. My goal is to be able share that bandwidth to sm’s.

If that is feasible, how is it? Thanks in advance,
