If the CM has multiple MAC addresses, this is the MAC address associated with the MAC Domain interface. When the record is a Group Service Flow, the MAC address should contain a multicast address compliant with either [RFC 2464] or [RFC 1112] as applicable Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::MacAddr This attribute uniquely identifies a CM. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::Id This attribute demotes the IPv4 address of the CM. If the CM has no IP address assigned, or the IP address is unknown, this object returns 0.0.0.0. If the CM has multiple IPv4 addresses, it contains the IPv4 address associated with the Cable (i.e., RF MAC) interface. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::Ipv4Addr This attribute denotes the IPv6 address of the CM. If the CM has no Internet address assigned, or the Internet address is unknown, the value of this attribute is the all zeros address. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::Ipv6Addr This attribute denotes the IPv6 local scope address of the CM. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::Ipv6LinkLocal This attribute denotes the queuing services the CM registered. Non DOCSIS 3.0 CMs will always report DOCSIS 1.1 QoS mode since DOCSIS 1.0 CoS mode was deprecated in DOCSIS 3.1. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::QosVersion DOCSIS 1.0 CoS mode DOCSIS 1.1 QoS mode This attribute denotes the current CM connectivity state. Returned status information is the CM status as assumed by the CMTS. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::Value This attribute denotes the last time the CM registered. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::LastRegTime This attribute indicates which, if any, of the Energy Management Features are enabled for this CM. If this attribute returns em1x1Mode(0) bit set, the CM is configured with the Energy Management 1x1 Feature enabled. If this attribute returns all bits cleared, the CM will not request to operate in any Energy Management mode of operation. Note: This attribute only indicates if an Energy Management Feature is enabled/disabled via the CM config file and registration request/response exchange and does not indicate whether the CM is actively operating in an Energy Management Mode. Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::EnergyMgtEnabled This attribute indicates whether the CM is currently operating in an Energy Management Mode. If this attribute returns em1x1Mode(0) bit set, the CM is operating in Energy Management 1x1 Mode. If this attribute returns all bits cleared, the CM is not operating in any Energy Management Mode. This attribute always returns 0x00 (no bits set) in the case when EnergyMgtEnabled is set to 0x00 (no Energy Management Features enabled). Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmRegStatus::EnergyMgtOperStatus This attribute indicates the total time duration, in seconds since registration, the CM identified by CmRegStatusId has been in Energy Management 1x1 mode, as controlled by the DBC-REQ Energy Management 1x1 Mode Indicator TLV. seconds Information Model Mapping: CM-SP-CCAP-OSSIv3.1 CmtsCmEmStats::Em1x1ModeTotalDuration
