Description: The service classes on an interface are partitioned into two subsets, dictating how a service class with a cell ready to transmit is chosen (subsequently a connection is chosen within the selected service class). There are two subsets: Strict Priority (SP), and Weighted Round Robin (WRR). The SP subset service classes are selected by strict priority (highest priority with available cell wins). If there are any SP service classes, they take precedence over any WRR classes. A WRR subset service class is chosen from among the WRR service classes with an available cell using a WRR algorithm. The SP service classes (if any) include a contiguous range of classes, starting with c2 (c1 is dedicated to CBR, which doesn't use SP/WRR). The WRR service classes (if any) include a contiguous range of classes, ending with c5. This object specifies the break-point between SP and WRR service classes. Note that (assuming all service classes are used) specifying c2 indicates all service classes are WRR, and specifying c5 indicates all service classes are SP.
