Description: Manages DOCSIS 3.0 cable interface objects including channel bonding and multiple channel configurations.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is DOCS-IF3-MIB?

This is a CableLabs/IETF-derived standards MIB (DOCS-IF3-MIB) that manages DOCSIS 3.0 cable modem interface objects, including channel bonding and multiple downstream/upstream channel configurations used on cable broadband networks. It exposes cable modem (CM) status data covering registration, ranging, and synchronization health as well as configuration for bonded channel groups. This MIB is heavily focused on monitoring hardware/software status of cable modems: it tracks resets, lost synchronizations, invalid MAP/UCD messages, invalid ranging and registration responses, and T1/T2 timer timeouts, all of which are classic indicators of a cable modem struggling to maintain a stable RF link. It builds directly on the base DOCSIS interface MIB framework and IETF/CableLabs DOCSIS specifications. It is typically deployed on cable modem termination systems (CMTS) and cable modems in HFC (hybrid fiber-coax) broadband access networks. Operators relying on the DOCS-IF3-MIB MIB gain visibility not just into individual modem health but into the bonded-channel-group configuration that underpins DOCSIS 3.0's higher throughput.

IPNetwork Monitor allows you to monitor SNMP objects defined in DOCS-IF3-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

DOCSIS 3.0 cable modem
cable modem termination system (CMTS)

Monitoring Examples

An administrator could poll docsIf3CmStatusTable/docsIf3CmStatusEntry for docsIf3CmStatusValue and docsIf3CmStatusCode to see the modem's registration state, then check docsIf3CmStatusResets, docsIf3CmStatusLostSyncs, and docsIf3CmStatusT1Timeouts to diagnose whether a modem is repeatedly dropping sync due to poor RF signal quality. Rising docsIf3CmStatusInvalidRangingRsps or docsIf3CmStatusInvalidRegRsps counts would point to upstream ranging or registration problems on that line.

What Can Be Monitored

cable modem registration status/code
modem reset count
lost synchronization events
invalid MAP/UCD message counts
invalid ranging/registration response counts
T1/T2 timer timeouts

docsIf3CmEventCtrlTable	1.3.6.1.4.1.4491.2.1.20.1.29		not-accessible	This object represents the control mechanism to enable the dispatching of events based on the event Id. The following rules define the event control behavior: - The CmEventCtrl object has no instances or contains an instance with Event ID 0. All events matching the Local Log settings of docsDevEvReporting are sent to local log ONLY. - The CmEventCtrl object contains configured instances Only events matching the Event Ids configured in the object are sent according to the settings of the docsDevEvReporting object. The CM does not persist instances of CmEventCtrl across reinitializations.
NTF docsIf3CmEventNotif	1.3.6.1.4.1.4491.2.1.20.0.2			A notification to report a DOCSIS event detected on the CM. This notification includes the following information: - docsDevEvLevel: the priority level associated with the event. - docsDevEvId: the unique identifier of the event that occurred. - docsDevEvText: a textual description of the event. - docsDevEvLastTime: The local date and time when this event was generated.
docsIf3CmGroup	1.3.6.1.4.1.4491.2.1.20.2.2.2			Group of objects implemented in a DOCSIS 3.0 CM
docsIf3CmMdCfgEntry	1.3.6.1.4.1.4491.2.1.20.1.31.1		not-accessible	The conceptual row of docsIf3CmMdCfgTable. The ifIndex key corresponds to the MAC Domain interface.
INT docsIf3CmMdCfgIpProvMode	1.3.6.1.4.1.4491.2.1.20.1.31.1.1	INTEGER	read-write	This attribute specifies whether the CM honors or ignores the CMTS MDD TLV 5.1 setting in order to configure its IP provisioning mode. The CM relies upon the CMTS to facilitate the successful IP address acquisition independently of the MDD. When this attribute is set to 'ipv4Only' the CM will initiate the acquisition of a single IPv4 address for the CM management stack. When this attribute is set to 'ipv6Only' the CM will initiate the acquisition of a single IPv6 address for the CM management stack. When this attribute is set to 'honorMdd' the CM will initiate the acquisition of an IPv6 or IPv4 address as directed by the MDD message for provisioning and operation.
T/F docsIf3CmMdCfgIpProvModeResetOnChange	1.3.6.1.4.1.4491.2.1.20.1.31.1.2	TruthValue	read-write	This attribute determines if the CM is to automatically reset upon change of the IpProvMode attribute. The attribute has a default value of 'false' (2) which means that the CM does not reset upon change to IpProvMode attribute. When this attribute is set to 'true' (1), the CM resets upon a change to the IpProvMode attribute.
U32 docsIf3CmMdCfgIpProvModeResetOnChangeHoldOffTimer	1.3.6.1.4.1.4491.2.1.20.1.31.1.3	Unsigned32	read-write	This attribute determines how long a CM with IpProvModeResetOnChange set to 'true' waits to reset. When the IpProvModeResetOnChange attribute is set to 'true' (1), the CM will decrement from the configured timer value before resetting. The default value of the IpProvModeResetOnChangeHoldOffTimer is 0 seconds which is equivalent to an immediate reset.
STO docsIf3CmMdCfgIpProvModeStorageType	1.3.6.1.4.1.4491.2.1.20.1.31.1.4	StorageType	read-write	This attribute determines if the CM persists the value of IpProvMode across a single reset or across all resets. The default value of this attribute is 'nonVolatile' (3) which means that the CM persists the value of IpProvMode across all resets. The CM persists the value of IpProveMode across only a single reset when IpProvModeStorageType is set to volatile(2). Other StorageType values are not applicable for this object; an attempt to set this object to a value of other(1), permanent(4), or readOnly(5) will be rejected with an error code of inconsistentValue.
docsIf3CmMdCfgTable	1.3.6.1.4.1.4491.2.1.20.1.31		not-accessible	This object contains CM MAC domain level control and configuration attributes.
docsIf3CmNotificationGroup	1.3.6.1.4.1.4491.2.1.20.2.2.4			CM is required to support notifications in this group
docsIf3CmSpectrumAnalysisCtrlCmd	1.3.6.1.4.1.4491.2.1.20.1.34
T/F docsIf3CmSpectrumAnalysisCtrlCmdEnable	1.3.6.1.4.1.4491.2.1.20.1.34.1	TruthValue	read-write	This attribute is used to enable or disable the spectrum analyzer feature. Setting this attribute to true triggers the CM to initiate measurements for the spectrum analyzer feature based on the other configuration attributes for the feature. By default, the feature is disabled unless explicitly enabled. Note that the feature may be disabled by the system under certain circumstances if the spectrum analyzer would affect critical services. In such a case, the attribute will return 'false' when read, and will reject sets to 'true' with an error. Once the feature is enabled, any Set operation on the docsIf3CmSpectrumAnalysisCtrlCmd MIB group might not be effective until the feature is re-enabled again.
U32 docsIf3CmSpectrumAnalysisCtrlCmdEquivalentNoiseBandwidth	1.3.6.1.4.1.4491.2.1.20.1.34.7	Unsigned32	read-write	This attribute allows the user to request an equivalent noise bandwidth for the resolution bandwidth filter used in the spectrum analysis. This corresponds to the spectral width of the window function used when performing a discrete Fourier transform for the analysis. The window function which corresponds to a value written to this object may be obtained by reading the value of the WindowFunction attribute. If an unsupported value is requested, the device may return an error, or choose the closest valid value to the one which is requested. If the closest value is chosen, then a subsequent read of this attribute will return the actual value which is in use.
U32 docsIf3CmSpectrumAnalysisCtrlCmdFirstSegmentCenterFrequency	1.3.6.1.4.1.4491.2.1.20.1.34.3	Unsigned32	read-write	This attribute controls the center frequency of the first segment for the spectrum analysis measurement. The frequency bins for this segment lie symmetrically to the left and right of this center frequency. If the number of bins in a segment is odd, the segment center frequency lies directly on the center bin. If the number of bins in a segment is even, the segment center frequency lies halfway between two bins. Changing the value of this attribute may result in changes to the docsIf3CmSpectrumAnalysisMeasTable. Note that if this attribute is set to an invalid value, the device may return an error, or may adjust the value of the attribute to the closest valid value.
INT docsIf3CmSpectrumAnalysisCtrlCmdInactivityTimeout	1.3.6.1.4.1.4491.2.1.20.1.34.2	INTEGER	read-write	This attribute controls the length of time after the last spectrum analysis measurement before the feature is automatically disabled. If set to a value of 0, the feature will remain enabled until it is explicitly disabled.
U32 docsIf3CmSpectrumAnalysisCtrlCmdLastSegmentCenterFrequency	1.3.6.1.4.1.4491.2.1.20.1.34.4	Unsigned32	read-write	This attribute controls the center frequency of the last segment of the spectrum analysis measurement. The frequency bins for this segment lie symmetrically to the left and right of this center frequency. If the number of bins in a segment is odd, the segment center frequency lies directly on the center bin. If the number of bins in a segment is even, the segment center frequency lies halfway between two bins. The value of the LastSegmentCenterFrequency attribute should be equal to the FirstSegmentCenterFrequency plus and integer number of segment spans as determined by the SegmentFrequencySpan. Changing the value of this attribute may result in changes to the docsIf3CmSpectrumAnalysisMeasTable. Note that if this attribute is set to an invalid value, the device may return an error, or may adjust the value of the attribute to the closest valid value.
U32 docsIf3CmSpectrumAnalysisCtrlCmdNumberOfAverages	1.3.6.1.4.1.4491.2.1.20.1.34.9	Unsigned32	read-write	This attribute controls the number of averages that will be performed on spectral bins. The average will be computed using the 'leaky integrator' method, where: reported bin value = alphaaccumulated bin values + (1-alpha)current bin value. Alpha is one minus the reciprocal of the number of averages. For example, if N=25, then alpha = 0.96. A value of 1 indicates no averaging. Re-writing the number of averages will restart the averaging process. If there are no accumulated values, the accumulators are made equal to the first measured bin amplitudes. If an attempt is made to set the attribute to an unsupported number of averages, an error will be returned.
U32 docsIf3CmSpectrumAnalysisCtrlCmdNumBinsPerSegment	1.3.6.1.4.1.4491.2.1.20.1.34.6	Unsigned32	read-write	This attribute controls the number of bins collected by the measurement performed for each segment (instance) in the docsIf3CmSpectrumAnalysisMeasTable. Note that if this attribute is set to an invalid value, the device may return an error, or may adjust the value of the attribute to the closest valid value.
U32 docsIf3CmSpectrumAnalysisCtrlCmdSegmentFrequencySpan	1.3.6.1.4.1.4491.2.1.20.1.34.5	Unsigned32	read-write	This attribute controls the frequency span of each segment (instance) in the docsIf3CmSpectrumAnalysisMeasTable. If set to a value of 0, then a default span will be chosen based on the hardware capabilities of the device. Segments are contiguous from the FirstSegementCenterFrequency to the LastSegmentCenterFrequency and the center frequency for each successive segment is incremented by the SegmentFequencySpan. The number of segments is (LastSegmentCenterFrequency - FirstSegmentCenterFrequency)/SegmentFrequencySpan + 1. A segment is equivalent to an instance in the docsIf3CmSpectrumAnalysisMeasTable. The chosen SegmentFrequencySpan affects the number of entries in the docsIf3CmSpectrumAnalysisMeasTable. A more granular SegmentFrequencySpan may adversely affect the amount of time needed to query the table entries in addition to possibly increasing the acquisition time. Changing the value of this attribute may result in changes to the docsIf3CmSpectrumAnalysisMeasTable. Note that if this attribute is set to an invalid value, the device may return an error, or may adjust the value of the object to the closest valid value.
SPE docsIf3CmSpectrumAnalysisCtrlCmdWindowFunction	1.3.6.1.4.1.4491.2.1.20.1.34.8	SpectrumAnalysisWindowFunction	read-write	This attribute controls or indicates the windowing function which will be used when performing the discrete Fourier transform for the analysis. The WindowFunction and the Equivalent Noise Bandwidth are related. If a particular WindowFunction is selected, then the EquivalentNoiseBandwidth for the function which is in use, will be reported by the EquivalentNoiseBandwidth attribute. Alternatively if an EquivalentNoiseBandwidth value is chosen then if a WindowFunction function representing that EquivalentNoiseBandwidth is defined in the CM, that value will be reported in the WindowFunction MIB object, or a value of 'other' will be reported. Use of 'modern' windowing functions not yet defined will likely be reported as 'other'. Note that all window functions may not be supported by all devices. If an attempt is made to set the object to an unsupported window function, or if writing of the WindowFunction is not supported, an error will be returned.

This measurement occurs prior to the point at which the desired CM signal, when present, is demodulated. The measurement includes the effect of the receive matched filter but does not include the effect of any ingress filtering. Both the signal power and noise/interference power are referenced to the same point, e.g., CMTS input.

ROW docsIf3RxChCfgRowStatus	1.3.6.1.4.1.4491.2.1.20.1.8.1.5	RowStatus	read-create	The status of this instance.
docsIf3RxChCfgTable	1.3.6.1.4.1.4491.2.1.20.1.8		not-accessible	The Receive Channel Configuration object permits an operator to configure how CMs registered with certain Receive Channel Profiles will configure the Receive Channels within their profile. When a CM registers with an RCP for which all Receive Channel Indices (RcIds) are configured in the Receive Module object and all Receive Channels are configured within this object, the CMTS should use the configuration within these objects to set the Receive Channel Configuration returned to the CM in a REG-RSP message. A CMTS may require configuration of all pertinent Receive Module and Receive Channel instances in order to register a CM that reports a Receive Channel Profile (RCP), including any standard Receive Channel Profiles. If the CM reports multiple RCPs, and Receive Module and Receive Channel objects have instances for more than one RCP, the particular RCP selected by the CMTS is not specified. A CMTS is not restricted to assigning Receive Modules based only on the contents of this object. This object supports the creation and deletion of multiple instances. Creation of a new instance of this object requires the ChIfIndex attribute to be set and a valid reference of a RccCfg instance.

When a CM registers with an RCP for which all Receive Module Indices (RmIds) are configured in this object and all Receive Channels are configured within the Receive Channel (ReceiveChannel) object, the CMTS should use the configuration within these objects to set the Receive Channel Configuration assigned to the CM in a REG-RSP message. A CMTS may require configuration of all pertinent Receive Module and Receive Channel instances (i.e., MIB table entries) in order to register a CM that reports a Receive Channel Profile. If the CM reports multiple RCPs, and Receive Module and Receive Channel objects have instances (i.e., MIB table entries) for more than one RCP reported by the CM, the particular RCP selected by the CMTS is not specified. A CMTS is not restricted to assigning Receive Modules based only on the contents of this object. This object supports the creation and deletion of multiple instances. Creation of a new instance of this object requires the reference of a valid RccCfg instance.

TEN docsIf3SignalQualityExtRxMER	1.3.6.1.4.1.4491.2.1.20.1.24.1.1	TenthdB	read-only	RxMER provides an in-channel received Modulation Error Ratio (MER). RxMER is defined as an estimate, provided by the demodulator, of the ratio: (average constellation energy with equally likely symbols) / (average squared magnitude of error vector) RxMER is measured just prior to FEC (trellis/Reed-Solomon) decoding. RxMER includes the effects of the HFC channel as well as implementation effects of the modulator and demodulator. Error vector estimation may vary among demodulator implementations. The CMTS RxMER is averaged over a given number of bursts at the burst receiver, which may correspond to transmissions from multiple users. In the case of S-CDMA mode, RxMER is measured on the de-spread signal.
