No, the MQC doesn't work like that. You can't have a cascading
policy like you could with the legacy rate-limit command. What you need
to do is mark the traffic on the ingress interfaces, and the run
fair-queue on the egress interface.
What John referred to is the ability of traffic policing to
separate traffic into different classes via IP Precedence or DSCP, but
this on its own doesn't dictate what happens to the classes. You need
two different policies, one to mark, another to perform the action based
on the marking.
