MIB Specifications
This chapter describes each Management Information Base (MIB) on the Cisco CMTS router. Each description lists any constraints on how the MIB or its object identifiers (OIDs) are implemented on the router.
Unless noted otherwise, the Cisco CMTS implementation of a MIB follows the standard MIB that has been defined. Any MIB table or object not listed the tables is implemented as defined in the standard MIB definition.
Note 
Not all MIBs included in a Cisco IOS software release are fully supported by the router. Some MIBs are not supported at all. Other MIBs might work, but they have not been tested on the router. In addition, some MIBs are deprecated but cannot be removed from the software. When a MIB is included in the image, this does not necessarily mean it is supported by the Cisco CMTS platform.
Note For information about how to avoid performance problems when you use Simple Network Management Protocol (SNMP) to poll the router for routing table entries, see the "High CPU Usage When Polling Routing ARP Tables" section on page 2-5.
Overview of MIB Support
Support for a particular MIB is included as part of the Cisco IOS software release. Each version of Cisco IOS software contains code that responds to SNMP requests for objects that are in the MIBs that are supported in that release for that particular software image.
Each new release of Cisco IOS software typically changes that support to some extent, usually involving one or more of the following:
•Fixing a caveat or software defect that is preventing the proper use of the MIB
•Updating the software to support the latest version of the MIB or to support optional objects that were not supported previously
•Adding support for new MIBs that are part of a new feature that is being introduced
The fact that a MIB might be included in a Cisco IOS software release does not imply that the MIB is fully supported on the router. Similarly, the fact that you can access a particular object in a MIB does not imply that the object is fully supported either.
Note As a general rule, deprecated objects and MIBs should not be used, because they have been replaced by other, more functional objects and MIBs. Also, deprecated objects and MIBs can be removed in a future release without notice.
Note The exact MIB support depends on both the Cisco IOS software image and the Cisco IOS software release being used. To determine which MIBs are included in other releases and software images, see the "Determining MIB Support for Cisco IOS Releases" section on page 2-1.
Table 3-1 lists the MIBs that are included in Cisco IOS Release 12.3BC for Cisco CMTS routers, through Cisco IOS Release 12.3(23)BC. Shaded cells indicate that the MIB is not included for that particular platform and software release. Unless otherwise indicated, each MIB is included in all software images for the indicated release. In some cases, MIBs that are included in the software image are not actually supported or are only partially supported.
Table 3-2 list the specific cable MIBs.

CISCO-CABLE-ADMISSION-CTRL-MIB
The CISCO-CABLE-ADMISSION-CTRL-MIB contains objects enabling the management of Cable Modem Termination System (CMTS) admission control. Admission Control refers to the rules that the Cisco CMTS follows when allocating and monitoring events for resources such as the following:
•CPU and memory utilization—Data and thresholds setting on the physical entity, such as the main processor or line card or Broadband processing Engines (BPE), when a monitoring event happens
•Configuration of thresholds and channel bandwidth utilization, both Upstream (US) and Downstream (DS), are based on application types
The monitored events for Admission Control on the Cisco CMTS include the following:
•Dynamic service flow creation requests—Dynamic service flow allows on-demand reservation on Layer 2 bandwidth resources. CMTS provides special QoS to the cable modem dynamically during a voice call or video session which provides a more efficient use of the available bandwidth.
•Resource requests during cable modem (CM) registration—CMTS resources are required during CM registration. CMTS resources are checked when CM receives a registration request.
Note For detailed information about admission control for Cisco CMTS, go to the following URL:

CISCO-CABLE-SPECTRUM-MIB
The CISCO-CABLE-SPECTRUM-MIB provides SNMP support for spectrum management and flap-list operations on the Cisco CMTS.
Spectrum management is a feature provided in the CMTS so that the CMTS may identify both downstream and upstream plant impairments, report them to a management entity, and automatically diminish them where possible.
The purpose of cable spectrum management is to:
•Prevent long-term service interruptions caused by upstream noise events in the cable plant
•Provide fault management and troubleshooting on the cable network. The following new tables and objects are supported in this MIB:
–ccsSpecGroupFreqTable
–ccsUpInSpecGroupTable
–ccsUpInCombGroupTable
–ccsUpSpecMgmtSpecGroup
–ccsUpSpecMgmtSharedSpectrum

Notes
|
ccsUpSpecMgmtTable
|
|
•ccsUpSpecMgmtSNR
|
This object returns zero (0) in three situations: when the actual signal-to-noise ratio (SNR) measures 0 (when ingress noise cancellation is being used), when no cable modems are online the upstream, or when the SNMP agent on the router could not determine a valid SNR value.
|
•ccsUpSpecMgmtSpecGroup
|
Read-only. The value of 0 for this object indicates that the upstream has no spectrum group assigned to it.
|
•ccsUpSpecMgmtSharedSpectrum
|
Read-only. The combiner group assigned to the upstream. Note: Upstreams having same combiner group number indicates that they physically combine together into the same RF domain and must have unique frequency assigned. The value of 0 for the object indicates that the upstream is not physically combine with any others.
|
ccsCmFlapTable
|
|
•ccsFlapAging
ccsFlapListMaxSize ccsFlapInsertionTime ccsFlapMissThreshold ccsFlapPowerAdjustThreshold ccsFlapResetAll, ccsFlapClearAll ccsFlapResetNow
•The following objects are supported in Cisco IOS release 12.3(23)BC and later releases:
ccsCmFlapDownstreamIfIndex
ccsCmFlapUpstreamIfIndex
ccsCmFlapMacAddr
|
These objects are supported on the Cisco uBR10012 router in Cisco IOS Release 12.2(11)BC3 and later releases.
Commencing in Cisco IOS Release 12.3(23)BC, This table keeps the records of modem state changes, and can be used to identify problematic cable modems. The system automatically adds an entry per modem to the table when it detects any state changes to the modem. This table can be deleted but cannot be added by the management system.
The index objects are ccsCmFlapDownstreamIfIndex, ccsCmFlapUpstreamIfIndex, ccsCmFlapMacAddr. This table is used to replace ccsFlapTable, using downstream, upstream and MAC address as indices for the flapped modem.
For NB CMs using SPA Downstream, ccsCmFlapDownstreamIfIndex should be the ifindex of Modular Cable Interface's snmp ifindex.

CISCO-CABLE-WIDEBAND-MIB
CISCO-CABLE-WIDEBAND-MIB in Cisco IOS 12.3(21)BC
The CISCO-CABLE-WIDEBAND-MIB contains objects that support Channel Bonding Protocol for the Cable Modem Termination System (CMTS). Cisco Cable Wideband MIB supports Wideband DOCSIS on the Cable Modem Termination System (CMTS). Wideband DOCSIS enhances per-cable-modem data rates that exceed the bandwidth of a single 256QAM downstream channel.
The MODULE-IDENTITY for the CISCO-CABLE-WIDEBAND-MIB is ciscoCableWidebandMIBObjects, and its top-level OID is 1.3.6.1.4.1.9.9.479.
A wideband channel or Bonded Group is a logical grouping of one or more physical RF channels over which MPEG-TS packets are carried. The wideband channel carries DOCSIS-bonded packets encapsulated in MPEG-TS packets from a wideband Cisco CMTS to one or more wideband cable modems.
Narrowband and Wideband Channels in Cisco IOS 12.3(23)BC
Commencing in Cisco IOS Release 12.3(23)BC and later releases, the Cisco CMTS supports a narrowband channel in a standard DOCSIS downstream channel containing exactly one RF channel. The fiber node in a narrowband channel is an optical node that terminates the fiber-based downstream signal as an electrical signal onto a coaxial RF cable. This type of narrowband channel is distinct from another new narrowband channel that applies to the Shared Port Adaptor (SPA) downstream channel.
Narrowband in Cisco IOS 12.3(23)BC has been enhanced to support two tables in the CISCO-CABLE-WIDEBAND-MIB:
•ccwbWBtoRFMappingTable
•ccwbWBtoNBMappingTable
These MIB objects correspond to the two following privileged EXEC commands:
•show hw-module bay all mapping wideband-channel
•show hw-module bay all association wideband-channel
MIB Notes and Constraints
The CISCO-CABLE-WIDEBAND-MIB has the following constraints.
