DOCSIS 3.0 Operations Support System Interface Specification CM-SP-OSSIv3.0-C01-171207. 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. 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. 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. Contains the direction of the SF from the CMTS cable interface. Downstream Upstream Contains a 64-bit absolute counter value of octets passed by this SF. Contains a 64-bit absolute counter value of octets passed by this SF. Contains a 32-bit absolute counter value of packets dropped exceeding SLA by this SF (Downstream only). Contains a 32-bit absolute counter value of packets delayed exceeding SLA by this SF (Downstream only). 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. Contains the total time that the Service Flow was active, specified in seconds.
