Well this all is configurable and I've seen some reference to the nesting
these policy-maps.
I could pull the class-d-policy map out of the class-default in the parent
map and use rate-limiting on the s0/0 interface to limit the ftp traffic as
well,
I have this configured and as soon as I can set up some traffic pairs to
that I can classify I will test this in the lab.
Just wondering if someone had tried to do this kind of differentiating and
what the effects they saw were.
