This read-write Integer32 (0..1000000) is the minimum bandwidth reserved for non-real-time VBR service as a percentage in xxx.xxxx format (e.g. 750000 = 75.0000%), and the combined total of cwspMinBwCbr, cwspMinBwRtVbr, cwspMinBwNrtVbr, cwspMinBwAbr, and cwspMinBwUbr cannot exceed 1000000 (100%). An administrator uses this to guarantee non-real-time VBR connections a bandwidth floor on the interface, ensuring that even under heavy contention from other service classes, non-real-time VBR traffic keeps a reserved slice of capacity. For example, setting cwspMinBwNrtVbr to 200000 (20%) while other classes' minimums sum to 60% leaves 20% of capacity unreserved and available for oversubscription across all classes.
