This object configures the beginning of the VPI range assigned to a resource partition, and connections provisioned on that partition must use a VPI greater than or equal to this value. An administrator uses this together with cwRsrcPartVpiHigh to carve out a dedicated VPI range so that connections in one partition cannot collide with VPIs used by another partition. For example, setting this to 10 would prevent any connection in this partition from being assigned a VPI below 10, reserving lower VPIs for other partitions or system use.
