DOCSIS 3.1 CCAP Operations Support System Interface Specification CCAP-OSSIv3.1-26.2430-1 Contains the set of channels configured for the service flow. Each octet represents the channel id of a channel. Contains the application identifier associated with the service flow. This attribute represents the ASF Identifier for the Aggregate Service Flow. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 AggregateServiceFlow::Id Indicates whether the service flow is multicast or unicast. A value of 'true' indicates a multicast service flow. A value of 'false' indicates a unicast service flow Contains a 32-bit Service Flow ID of the SF, in decimal notation. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 ServiceFlow::Id Contains a 32-bit GateID of the SF, or zero if not applicable, in decimal notation. Contains the Service Class Name (SCN) of the Service Flow. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 ParamSet::ServiceClassName This attribute indicates the ASF QoS Profile Name associated with this object instance. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 AggregateServiceFlow::AsfQosProfileName Contains the direction of the SF from the CMTS cable interface. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 ServiceFlow::Direction Downstream Upstream This attribute reports the type of the Service Flow. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 ServiceFlow::Type Other Other represents an undefined Service Flow type. Standalone Standalone represents a standalone Service Flow that is not associated with an ASF. Classic Classic represents a classic Service Flow associated with a Low Latency ASF. LowLatency LowLatency represents a Low Latency Service Flow associated with a Low Latency ASF. NonLldHqos NonLldHqos represents a Service Flow that is a constituent of an Aggregate Service Flow (ASF) but the ASF is not a Low Latency ASF. AggregateServiceFlow AggregateServiceFlow represents an Aggregate Service Flow. Contains a 64-bit absolute counter value of octets passed by this SF. bytes Information Model Mapping: CM-SP-CCAP-OSSIv3.1 ServiceFlowStats::Octets Contains a 64-bit absolute counter value of octets passed by this SF. packets Information Model Mapping: CM-SP-CCAP-OSSIv3.1 ServiceFlowStats::Pkts Contains a 32-bit absolute counter value of packets dropped exceeding SLA by this SF (Downstream only). packets Information Model Mapping: CM-SP-CCAP-OSSIv3.1 ServiceFlowStats::PolicedDropPkts Contains a 32-bit absolute counter value of packets delayed exceeding SLA by this SF (Downstream only). packets Information Model Mapping: CM-SP-CCAP-OSSIv3.1 ServiceFlowStats::PolicedDelayPkts For downstream service flows on which Active Queue Management is enabled, this attribute reports the count of the number of Packet Data PDUs classified to this service flow dropped due to Active Queue Management drop decisions. Counts of classified packets dropped due to other reasons are reported in either PolicedDropPkts or ifOutDiscards for the interface of this service flow, depending on the reason for the discard. The CCAP reports zero for this attribute for upstream service flows. packets Information Model Mapping: CM-SP-CCAP-OSSIv3.1 ServiceFlowStats::AqmDroppedPkts This attribute counts the number of packets redirected from the Low Latency Service Flow to the Classic Service Flow. For other Service Flow types in the CCAP, this counter reports 0. packets Information Model Mapping: CM-SP-CCAP-OSSIv3.1 SfCongestionStats::SanctionedPkts This attribute reports the count of packets that arrived marked as ECT0. This attribute includes only those packets classified into the Service Flow, not those sanctioned into the Service Flow. packets Information Model Mapping: CM-SP-CCAP-OSSIv3.1 SfCongestionStats::ArrivedEct0Pkts This attribute reports the count of packets that arrived marked as ECT1. This attribute includes only those packets classified into the Service Flow, not those sanctioned into the Service Flow. packets Information Model Mapping: CM-SP-CCAP-OSSIv3.1 SfCongestionStats::ArrivedEct1Pkts This attribute reports the count of packets that arrived marked as ECT1 and were re-marked as Congestion Experienced (CE) by the CCAP. This attribute includes only those packets classified into the Service Flow, not those sanctioned into the Service Flow. packets Information Model Mapping: CM-SP-CCAP-OSSIv3.1 SfCongestionStats::CeMarkedEct1Pkts This attribute reports the count of packets that arrived marked as Congestion Experienced (CE). This attribute includes only those packets classified into the Service Flow, not those sanctioned into the Service Flow. packets Information Model Mapping: CM-SP-CCAP-OSSIv3.1 SfCongestionStats::ArrivedCePkts Contains the value of CmtsSysUpTime when the Service Flow was created for DOCSIS QOS CM provisioning. For DOCSIS COS CM provisioning (optionally supported only by 3.0 CMTSs), it is the time the non-temporary SID is created. For downstream CM traffic it indicates the time the CM registers. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 ServiceFlowLog::TimeCreated Contains the total time that the Service Flow was active, specified in seconds. seconds Information Model Mapping: CM-SP-CCAP-OSSIv3.1 ServiceFlowLog::TimeActive
