mscAtmIfCARtVbrUsageParameterControl 1.3.6.1.4.1.562.36.2.1.114.3.3.100.1.89

This attribute specifies the default usage parameter control (UPC) option for connections of the rt-VBR service category. This attribute is ignored if the rxTrafficDescriptorType indicates 1 or 2. An override to this default may be specified for a provisioned connection under the Vcd Tm or Vpd Tm component. When this attribute is set to enforced, UPC is enforced for each connection. When UPC is enforced, non-conforming cells are either tagged or discarded depending on the rxTrafficDescriptorType. On ATM IP FPs, when this attribute is set to monitored, UPC conformance checking is performed, except, instead of the non- conforming cells being tagged or discarded, they are merely counted in the UPC violations counts, and passed on unchanged. On CQC-based ATM FPs, when this attribute is set to monitored, it has the same effect as setting it to disabled. When this attribute is set to disabled, UPC is disabled on the receive path for all rt-VBR connections. This attribute does not apply to basic Vpts, and standard Vpt Vccs.
