Is this because it's applied on ingress to a vlan? I'm asking this as I know
applying service-policies to vlans can be tricky as it's a virtual interface
as far as the switch is concerned so what does the swutch see as in/egress
in relation to the vlan.

One match per class is due to the logic which can only handle one action per
pass. Adding hierarchy makes the 'packet' go through the logic again. (Am I
wrong? This is what I see with hardware based routing logic)

I figure I have some labbing to do on my 3560 tonight. Any
input/corrections/references welcome!
