atmIfVptVccTmUsageParameterControl 1.3.6.1.4.1.562.2.4.1.114.9.20.7.100.1.80

This attribute indicates the UPC state of the connection. A value of notApplicable indicates that UPC is not applicable or not supported for the connection. This is the case: - when the connection's rxTrafficDescType is 1 or 2. - for standard Vpt Vccs and basic Vpts. A value of notApplicable is set regardless of whether UPC is disabled or enabled in provisioning data. A value of disabled indicates that UPC is applicable and supported for the type of connection but has been turned off in the provisioning data. A value of enforced indicates that UPC is actively checking conformance for the connection and is discarding or tagging cells which do not conform to the connection traffic contract. The traffic descriptor parameters used for UPC conformance are reflected in the rxTrafficDescParms of the connection. On ATM IP cards, the counts of UPC violations are visible in the Vcc, Vpc, or Vpt rxUpcViolationsOnEnforcer1 or rxUpcViolationsOnEnforcer2 attributes. ATM IP cards provide the ability to monitor UPC violations without tagging or discarding. A value of monitored indicates that UPC is actively checking conformance for the connection and counting the violations, but is not discarding or tagging cells which do not conform to the connection traffic contract. The traffic descriptor parameters used for UPC conformance are reflected in the rxTrafficDescParms of the connection. The counts of UPC violations are visible in the Vcc, Vpc, or Vpt rxUpcViolationsOnEnforcer1 or rxUpcViolationsOnEnforcer2 attributes. The value of monitored appears only on ATM IP cards. If the atmServiceCategory for this connection indicates availableBitRate, a value of abrEnforced indicates that Dynamic Generic Cell Rate Algorithm (DGCRA) is active for the connection and that violating cells are discarded. The cell rate which is in effect at any particular instant is indicated in rxTrafficDescParm 4 of the connection. If the atmServiceCategory for this connection indicates availableBitRate, a value of abrMonitored indicates that Dynamic Generic Cell Rate Algorithm (DGCRA) is active for the connection but that violating cells are counted only. The cell rate which is in effect at any particular instant is indicated in rxTrafficDescParm 4 of the connection.
