This object configures the low end of the VPI range for an SVC aggregate, which must be greater than or equal to the containing resource partition's cwRsrcPartVpiLo, and SVC connections provisioned on the aggregate must use a VPI at or above this value. An administrator uses this to subdivide a resource partition's VPI range further for switched virtual circuit traffic specifically. For example, if the partition's VpiLo is 10, an administrator could set this SVC aggregate's low VPI to 12 to reserve VPIs below that for other, non-SVC uses within the same partition.
