Description: Manages DOCSIS 3.1 cable interface objects including OFDM channel configuration and OFDMA upstream management.

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-IF31-MIB?

DOCS-IF31-MIB is a CableLabs standards-track MIB module that defines management objects for DOCSIS 3.1 features, primarily the new OFDM downstream and OFDMA upstream channel technologies used by cable modems (CMs) and CMTS/CCAP platforms. It exposes objects such as docsIf31RxChStatusTable (CM primary/backup OFDM profile indication via docsIf31RxChStatusPrimaryDsIndicator), docsIf31CmtsCmRegStatusTable (CMTS-side registration extensions like docsIf31CmtsCmRegStatusDsProfileIdList and docsIf31CmtsCmRegStatusUsProfileIucList), and channel/profile status tables including docsIf31CmDsOfdmChanTable, docsIf31CmUsOfdmaChanTable, docsIf31CmtsDsOfdmProfileStatsTable, and docsIf31CmtsUsOfdmaChanTable. This data is central to monitoring OFDM/OFDMA channel health, profile assignment, and Energy Management DLS state (docsIf31CmStatusEmDlsOperStatus) on modern DOCSIS 3.1 access networks. It builds on and extends DOCS-IF-MIB and DOCS-IF3-MIB, and is deployed alongside those modules on CMTS/CCAP head-end equipment and DOCSIS 3.1 cable modems. Cable operators and equipment vendors implementing OFDM/OFDMA plant rely on the DOCS-IF31-MIB MIB to expose this channel and profile-level telemetry to SNMP-based monitoring systems.

IPNetwork Monitor allows you to monitor SNMP objects defined in DOCS-IF31-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

CableLabs-certified DOCSIS 3.1 cable modems (CMs)
CMTS / CCAP head-end platforms

Monitoring Examples

An operator polls docsIf31CmtsCmUsOfdmaChannelStatusTable and docsIf31CmtsCmDsOfdmChannelStatusTable to check per-modem OFDM/OFDMA channel assignment and profile usage across a CCAP, cross-referencing docsIf31CmDsOfdmProfileStatsTable counters for correctable/uncorrectable codeword rates; a rising uncorrectable count alongside an unexpected docsIf31RxChStatusPrimaryDsIndicator value would flag a modem falling back off its primary OFDM profile due to plant impairment.

What Can Be Monitored

OFDM downstream channel status and profile assignment
OFDMA upstream channel status and minislot configuration
CM registration profile/IUC lists
downstream/upstream profile statistics (codeword error counts)
Energy Management DLS operating status
downstream channel power per subcarrier

How to Use in IPNetwork Monitor

Example using docsIf31CmtsCmUsOfdmaChannelNumPartialSvcIncidents OID:

Select a DOCSIS 3.1 cable modem/CMTS-CCAP (OFDM/OFDMA channels, vendor-neutral CableLabs standard) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type docsIf31CmtsCmUsOfdmaChannelNumPartialSvcIncidents into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. This attribute returns the number of Partial Service incidents the MAC layer has reported for this CM on this upstream OFDMA channel. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

Profile ID 0 is commonly referred to as Profile A. Likewise, Profile IDs 1, 2 and 3 are commonly referred to as Profiles B, C and D. The CCAP encodes each OFDM channel in a CM's RCS as a separate n-octet entry in the ProfileIdList. Examples: a CM with a single OFDM channel (ifIndex 34) and four assigned profiles (Profile IDs 0, 8, 9 and 10) would have a ProfileIdList value of 0x00000022040008090A. A CM with a 2 OFDM channel bonding group each with two assigned profiles (Profile IDs 0 and 15 on channel with ifIndex 34 and Profile IDs 0 and 14 on channel with ifIndex 35) would have a ProfileIdList value of 0x0000002202000F0000002302000E). Note: the CCAP must not include the transitional profile or test profile in the ProfileIdList. Note that octet string lengths greater than 18 are optional.

The CCAP encodes each OFDMA channel in a CM's TCS as a separate n-octet entry in the UsProfileIucList. Examples: a CM with a single OFDMA channel (ifIndex 36) and two assigned Data IUCs (5 and 6) would have a ProfileIdList value of 0x00000024020506. A CM with a 2 OFDMA channel bonding group each with one assigned Data IUC (IUC 5 on channel with ifIndex 34 and IUC 13 on channel with ifIndex 35) would have a UsProfileIucList value of 0x00000022010500000023010D). Note: the CCAP MUST NOT include transitional IUCs or test IUCs in the UsProfileIucList. Note that octet string lengths greater than 18 are optional.

The mean is computed directly on the dB values as follows: Mean = sum of (RxMER dB values) / number of RxMER values
HUN docsIf31CmtsCmUsOfdmaChannelStdDevRxMer	1.3.6.1.4.1.4491.2.1.28.1.4.1.3	HundredthdB	read-only	This attribute is the standard deviation of the dB values of the RxMER measurements of all active subcarriers. The standard deviation is computed directly on the dB values as follows: StdDev = sqrt(sum of (RxMER dB vals - RxMER_mean)^2 / # RxMER vals)
U32 docsIf31CmtsCmUsOfdmaChannelRxMerThreshold	1.3.6.1.4.1.4491.2.1.28.1.4.1.4	Unsigned32	read-write	This attribute specifies the percentile (such as 2nd percentile or 5th percentile) of all active subcarriers in an OFDM channel at which the ThresholdRxMerValue occurs. That is, (Percentile) % of the subcarriers have RxMER <= ThresholdRxMerValue.
HUN docsIf31CmtsCmUsOfdmaChannelThresholdRxMerValue	1.3.6.1.4.1.4491.2.1.28.1.4.1.5	HundredthdB	read-only	This attribute is the RxMER value corresponding to the specified docsIf31CmtsCmUsOfdmaChannelRxMerThreshold percentile value. The CCAP sorts the subcarriers in ascending order of RxMER, resulting in a post-sorting subcarrier index ranging from 1 to the number of active subcarriers. If the percentile value corresponds to a non- integer post-sorting subcarrier index, the post-sorting index is truncated (floor function is applied); that is, the post-sorting index is selected which is the greatest integer less than or equal to the corresponding percentile value. For example, if there are 3677 active subcarriers and the 2nd percentile is specified, the CCAP computes floor(3677*0.02) = 73. That is, the RxMER value of the 73rd subcarrier in the sorted list is associated with the 2nd percentile. This is displayed in hundredth of a dB, but is only accurate to a quarter dB.

DSO docsIf31CmDsOfdmChanRollOffPeriod	1.3.6.1.4.1.4491.2.1.28.1.9.1.9	DsOfdmRollOffPeriod	read-only	Roll off period maximizes channel capacity by sharpening the edges of the spectrum of the OFDM signal. For windowing purposes another segment at the start of the IDFT output is appended to the end of the IDFT output - the roll-off postfix (RP). There are five possible values for the (RP), and the choice depends on the bandwidth of the channel and the number of exclusion bands within the channel. A larger RP provides sharper edges in the spectrum of the OFDM signal; however, there is a time vs. frequency trade-off. Larger RP values reduce the efficiency of transmission in the time domain, but because the spectral edges are sharper, more useful subcarriers appear in the frequency domain. There is an optimum value for the RP that maximizes capacity for a given bandwidth and/or exclusion band scenario.

DSO docsIf31CmtsDsOfdmChanRollOffPeriod	1.3.6.1.4.1.4491.2.1.28.1.19.1.15	DsOfdmRollOffPeriod	read-only	Roll off period maximizes channel capacity by sharpening the edges of the spectrum of the OFDM signal. For windowing purposes another segment at the start of the IDFT output is appended to the end of the IDFT output - the roll-off postfix (RP). There are five possible values for the (RP), and the choice depends on the bandwidth of the channel and the number of exclusion bands within the channel. A larger RP provides sharper edges in the spectrum of the OFDM signal; however, there is a time vs. frequency trade-off. Larger RP values reduce the efficiency of transmission in the time domain, but because the spectral edges are sharper, more useful subcarriers appear in the frequency domain. There is an optimum value for the RP that maximizes capacity for a given bandwidth and/or exclusion band scenario.

U32 docsIf31CmtsUsOfdmaChanUtilization	1.3.6.1.4.1.4491.2.1.28.1.23.1.22	Unsigned32	read-only	The calculated and truncated utilization for this physical upstream channel, accurate as of the most recent docsIfCmtsChannelUtilizationInterval. The upstream channel utilization is expressed as a percentage of minislots utilized on the physical channel, regardless of burst type. The utilization calculation can be expressed by the following equation: Utilization = MinislotsUtilized/MinislotsAllocated * 100% For an Initial Maintenance region, the minislots for the complete region are considered utilized if the CMTS received an upstream burst within the region from any CM on the physical channel. For contention REQ and REQ/DATA regions, the minislots for a transmission opportunity within the region are considered utilized if the CMTS received an upstream burst within the opportunity from any CM on the physical channel. For all other regions, utilized minislots are those in which the CMTS granted bandwidth to any unicast SID on the physical channel. For an upstream interface that has multiple logical upstream channels enabled, the utilization index is a weighted sum of utilization indices for the logical channels. The weight for each utilization index is the percentage of upstream mini-slots allocated for the corresponding logical channel. Example: If 75% of bandwidth is allocated to the first logical channel and 25% to the second, and the utilization for each are 60 and 40, respectively, the utilization for the upstream physical channel is (60 * 0.75) + (40 * 0.25) = 55. This figure applies to the most recent utilization interval.
