[c-nsp] 3550 and QoS, prioritising on egress interface depending on ingress interface

[Saku Ytti]

 Setup is 3550 switch with one port towards Internet and rest towards
customer LAN.
 Customer would want that egress traffic is prioritized depending on
which interface packet ingressed the switch. Not really product
that we offer or support, but apparently I don't have enough to
do, as I started to ponder how it could be done.

 Should this work?
mls qos
!
int fa0/1
 desc internet
 wrr-queue bandwidth 1 40 1600 64000
 wrr-queue cos-map 1 0 1
 wrr-queue cos-map 2 2 3
 wrr-queue cos-map 3 4
 wrr-queue cos-map 4 5 6 7
!
int range macro highprio
 mls qos cos 7
 mls qos cos override
!
int range macro medprio
 mls qos cos 4
 mls qos cos override
!
int range macro lowprio
 mls qos cos 3
 mls qos cos override
!
int range macro trashprio
 mls qos cos 1
 mls qos cos override
!

Or is there some more sane approach to this?
