Description: Implements IETF DOCSIS Radio Frequency Interface (RFI) MIB for managing upstream and downstream CMTS channels.

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-IETF-RFI-MIB?

DOCS-IETF-RFI-MIB is the IETF/CableLabs DOCSIS 2.0 Radio Frequency Interface MIB, used for managing the RF characteristics of upstream and downstream channels on both Cable Modems (CM) and Cable Modem Termination Systems (CMTS). It exposes physical-layer configuration and status objects for downstream channels (frequency, width, modulation, interleave depth, power) and upstream channels (channel ID and related parameters), organized under base, downstream, and upstream object groups. Its core monitoring value is RF performance status: tracking downstream power levels and modulation profiles reveals signal quality degradation, and upstream channel parameters help diagnose noise or ingress issues affecting cable modem connectivity. It is a standards-based MIB that typically works alongside DOCS-IF-MIB/DOCS-IF3-MIB and vendor CMTS MIBs for a complete picture of DOCSIS plant health. It is deployed throughout HFC (hybrid fiber-coax) cable access networks on both CMTS headend equipment and subscriber cable modems. Engineers implementing or auditing this functionality typically reference the DOCS-IETF-RFI-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in DOCS-IETF-RFI-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 cable modem
DOCSIS CMTS (cable modem termination system)

Monitoring Examples

An operator would poll docsIfDownstreamChannelTable/docsIfDownstreamChannelEntry for docsIfDownChannelFrequency, docsIfDownChannelPower, and docsIfDownChannelModulation to verify each downstream channel is operating at expected power and modulation profile, and check docsIfUpstreamChannelTable/docsIfUpChannelId for upstream channel configuration. A downstream channel showing power drifting low or an unexpected modulation fallback (e.g., from 256QAM to a lower order) would indicate plant noise or amplifier issues degrading signal quality. This RF-layer data under docsIfBaseObjects/docsIfCmObjects is fundamental to diagnosing cable plant health issues affecting subscriber connectivity.

How to Use in IPNetwork Monitor

Example using docsIfSigQUnerroreds OID:

Select a DOCSIS 2.0 cable modem/CMT (RF interface, vendor-neutral IETF/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 docsIfSigQUnerroreds 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. Codewords received on this channel without error. This includes all codewords, whether or not they were part of frames destined for this device. 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.

docsIfCmtsChannelUtilizationEntry	1.3.6.1.2.1.10.127.1.3.9.1		not-accessible	Utilization statistics for a single upstream or downstream physical channel. An entry exists in this table for each ifEntry with an ifType equal to docsCableDownstreamInterface (128) or docsCableUpstreamInterface (129).
I32 docsIfCmtsChannelUtilizationInterval	1.3.6.1.2.1.10.127.1.3.8	Integer32	read-write	The time interval in seconds over which the channel utilization index is calculated. All upstream/downstream channels use the same docsIfCmtsChannelUtilizationInterval. Setting a value of zero disables utilization reporting. A channel utilization index is calculated over a fixed window applying to the most recent docsIfCmtsChannelUtilizationInterval. It would therefore be prudent to use a relatively short docsIfCmtsChannelUtilizationInterval.
docsIfCmtsChannelUtilizationTable	1.3.6.1.2.1.10.127.1.3.9		not-accessible	Reports utilization statistics for attached upstream and downstream physical channels.
I32 docsIfCmtsChannelUtUtilization	1.3.6.1.2.1.10.127.1.3.9.1.3	Integer32	read-only	The calculated and truncated utilization index for this physical upstream or downstream channel, accurate as of the most recent docsIfCmtsChannelUtilizationInterval. Upstream Channel Utilization Index: The upstream channel utilization index is expressed as a percentage of minislots utilized on the physical channel, regardless of burst type. 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 minislots 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 indices for each are 60 and 40 respectively, the utilization index for the upstream physical channel is (60 * 0.75) + (40 * 0.25) = 55. This figure applies to the most recent utilization interval. Downstream Channel Utilization Index: The downstream channel utilization index is a percentage expressing the ratio between bytes used to transmit data versus the total number of bytes transmitted in the raw bandwidth of the MPEG channel. As with the upstream utilization index, the calculated value represents the most recent utilization interval. Formula: Downstream utilization index = (100 * (data bytes / raw bytes)) = (100 * ((raw bytes - stuffed bytes) / raw bytes)) Definitions: Data bytes: Number of bytes transmitted as data in the docsIfCmtsChannelUtilizationInterval. Identical to docsIfCmtsDownChannelCtrUsed Bytes measured over the utilization interval. Stuffed bytes: Number of filler bytes transmitted as non-data in the DocsIfCmtsChannelUtilizationInterval. Raw bandwidth: Total number of bytes available for transmitting data, not including bytes used for headers and other overhead. Raw bytes: (raw bandwidth * docsIfCmtsChannelUtilizationInterval). Identical to docsIfCmtsDownChannelCtrTotal Bytes measured over the utilization interval.

ROW docsIfUpChannelStatus	1.3.6.1.2.1.10.127.1.1.2.1.18	RowStatus	read-create	This object is generally intended to be used for the creation of a temporary inactive upstream row for the purpose of adjusting the SCDMA channel parameters of an active upstream row. The recommended procedure is: 1) Create an inactive row through an SNMP SET using createAndWait(5). Use an ifIndex value outside the operational range of the system. 2) Set the docsIfUpChannelCloneFrom field to the ifIndex value of the active row whose SCDMA parameters require adjustment. 3) Adjust the SCDMA parameter values using the new temporary inactive row. 4) Update the active row by setting object docsIfUpChannelUpdate to TRUE. This SET will fail if the adjusted SCDMA parameters are not compatible with each other. 5) Delete the temporary row through an SNMP SET using DELETE. The following restrictions apply to this object: 1) This object must contain a value of active(1) for active rows. 2) Temporary inactive rows must be created using createAndWait(5). 3) The only possible status change of a row created using createAndWait(5) (ie notInService(2)) is to destroy(6). These temporary rows must never become active. 4) A status transition from active (1) to destroy (6) is not permitted. Entries with docsIfUpChannelStatus set to active(1) are logically linked to a physical interface, not temporarily created to clone parameters. The Interface MIB [RFC2863] ifAdminStatus should be used to take an Upstream Channel offline. Although this object was created to facilitate SCDMA parameter adjustment, it may also be used at the vendor's discretion for non-SCDMA parameter adjustment.
