I don't have the IE stuff, so I'm just taking a stab here, but there were a
few words in your description to me that screamed MQC. If you want to do
FRTS on a single PVC without affecting other traffic, I would use MQC. The
"traditional" methods require you to enable adaptive shaping on the physical
interface, which auto sets the CIR at 56K for every PVC on that physical
interface - *affects network performance*; bad for business unless you
already have other policies configed for these PVCs ahead of time, or you
really *want* that to happen. Disclaimer: This is me rambling from the top
of my head, I don't have the IE workbooks, but that is how I interpreted
your description of the tasks; it sounded to me like they were steering you
away from using the adaptive shaping on the physical interface.
Thanks,
Chris
