RE: MSLQoS marking IP Prec from one SVI to another SVI on 3560

On a 6500 you use an ingress policer to accomplish this with
set-prec-transmit. I'm afraid this is different from platform to platform,
but all are semi close. I always pull out Kevin Turek's Networkers
presentation for this kind of stuff. The QoS SRND should have examples of
this as well.
