mscAtmIfCAUbrUsageParameterControl
1.3.6.1.4.1.562.36.2.1.114.3.6.100.1.22
This attribute specifies the default usage parameter control (UPC)
option for connections of the UBR 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 UBR connections.
This attribute does not apply to basic Vpts, and standard Vpt Vccs.
