Re: [c-nsp] How to limit bandwidth on CISCO switch interfaces
Andy, When you say globally, are you referring to Qos on those two involved switches only?

Shaped queue does NOT shrink with bandwidth limit configured for the interface like one would expect. You either need to reassign weight, as shaping value is always calculated relative to physical bandwidth, or eliminate shaping all together.
