First of all, thankyou very much for choosing to do the doc like this. 
It is nice to see this format starting to get used.

The wording here is a little odd, given that no hardware currently
supports both L2 and L3.

It might be easier to say:

L2 CAT is independent of L3 CAT/CDP, and both may be enabled at the same

Otherwise, everything else looks great.
