Cisco CMTS Universal Broadband Series Router MIB Specifications Guide 12.2 BC

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.

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Note As a general rule, deprecated objects and MIBs should not be used, because they have been replaced by other, more functional objects and MIBs.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.

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-CLASS-BASED-QOS-MIB

The CISCO-CLASS-BASED-QOS-MIB provides access to quality of service (QoS) configuration information and statistics. The MIB uses several indexes to identify QoS features and distinguish among instances of those features:

•cbQosPolicyIndex—Identifies a service policy attached to a logical interface.

•cbQosObjectsIndex—Identifies each QoS feature on a Cisco uBR7200 and the uBR10k routers.

•cbQosConfigIndex—Identifies a type of QoS configuration. This index is shared by QoS objects that have identical configurations.

The indexes cbQosPolicyIndex and cbQosObjectsIndex are assigned by the system to uniquely identify each instance of a QoS feature.

Note Do not reuse these indexes between router reboots, even if the QoS configuration changes.

QoS information is stored in:

•Configuration objects—Might have multiple identical instances. Multiple instances of the same QoS feature share a single configuration object, which is identified by cbQosConfigIndex.

•Statistics objects—Each has a unique run-time instance. Multiple instances of a QoS feature have a separate statistics object. Run-time instances of QoS objects are each assigned a unique identifier (cbQosObjectsIndex) to distinguish among multiple objects with matching configurations.

The MODULE-IDENTITY for the CISCO-CLASS-BASED-QOS-MIB is ciscoCBQosMIB, and its top-level OID is 1.3.6.1.4.1.9.9.166 (iso.org.dod.internet.private.enterprises.cisco.ciscoMgmt.ciscoCBQosMIB).

.

Note When using docsIfCmtsQosProfilePermissions to remove the create by modem permission from cable modems, prohibits only future activity by cable modems and deletes only unused QoS profiles that have been created by cable modems; it does not affect QoS profiles that are currently in use. This behavior is different than the no cable qos permission modem command, which immediately deletes QoS profiles that have been created by the cable modems and takes those modems offline.

Note The docsIfCmtsChannelUtilizationInterval attribute retains its value after a reboot even though it is not visible in the output of show run command.

Constraints in Cisco IOS Release 12.3(23)BC

There are no entries for the narrowband SPA downstream channels for the tables docsIfDownstreamChannelTable and docsIfCmtsDownChannelCounterTable in Cisco IOS Release 12.3(23)BC. Note that the CISCO-CABLE-WIDEBAND-MIB MIB contains narrow band information.

However, the following changes are introduced in Cisco IOS release 12.3(23)BC:

DOCS-DSG-IF-MIB

This is the MIB Module for the DOCSIS Set-top Gateway(DSG). The DSG provides a one-way IP datagram transport for Out-Of-Band (OOB) messaging to cable set-top clients. The one-way IP datagram transport is called a DSG Tunnel. A DSG Tunnel carrying either a broadcast, unicast or multicast IP datagram stream originating at the DOCSIS Set-top Gateway and carrying Out-Of-Band messages intended for set-top clients. It is carried over one or more downstream DOCSIS channels. Multiple DSG tunnels may exist on a single downstream DOCSIS channel.

The following MIB tables were added with this release:

•dsgIfClassifierTable—Contains attributes use to classify inbound packets into the tunnel and classifiers for the DSG clients, encoding in the DCD messages on the downstream channels to which the classifiers apply.

•dsgIfTunnelTable—Contains group(s) of tunnel(s). Each tunnel is associated to the destination MAC address and associated to the QOS service class name.

•dsgIfTunnelGrpToChannelTable—Associates a group of tunnels to one or more downstream channel.

•dsgIfDownstreamChannelTable—Contains the associated timers, vendor specific parameters index and the channel list index to a specific downstream.

•dsgIfClientIdTable—Contains the client identification type and value. It also contains the vendor specific parameter identification.

•dsgIfVendorParamTable—Allows vendors to send specific parameters to the DSG clients within a DSG rule or within the DSG Configuration block in a DCD message.

•dsgIfChannelListTable—Contains list of one or multiple downstream frequencies that are carrying DSG tunnel(s).

•dsgIfTimerTable—Contains timers that are sent to the DSG client(s) through the DCD message.

Note DOCS-DSG-IF-MIB does not support Route Processor Redundancy Plus (RPR+) mode.

Note The DOCS-DSG-IF-MIB defines objects that are used to configure, control, and monitor the operation of the DOCSIS Set-top Gateway (DSG) 1.0 feature on Cisco uBR7200 series and Cisco uBR10012 routers. For detailed information about DOCSIS DSG, go to:
http://www.cisco.com/en/US/products/hw/cable/ps2217/products_feature_guide09186a00802065c8.html

MIB Constraints

Prior to Cisco IOS Release 12.3(23)BC, there are no constraints on the DOCS-DSG-IF-MIB. (All objects listed in this MIB are implemented as defined in the MIB definition.)

Wideband Support in Cisco IOS Release 12.3(23)BC

The DOCS-DSG-IF-MIB is defined to manage DOCSIS Set-top Gateway interfaces in the following manner.

•DSG is configured on the MC interface's CGD master interface.

•A packet transmits via Multicast to the DOCSIS Set-top Gateway (DSG).

•Cisco IOS uses an IGMP configuration command to control the packets.

In Cisco IOS Release 12.3(23)BC and later, Cisco IOS no longer accepts SNMP that is mapped in the the dsgIfTunnelGrpToChannelTable on MC interface. In this circumstance, an INCONSISTENT_VALUE_ERROR system message is reported, and a corresponding error message is prompted as follows:

Cannot set dsg tunnel group to Modular-Cable interface, set on CGD's host downstream instead.

DOCS-QOS-MIB

The DOCS-QOS-MIB contains objects to configure and monitor the QoS features that are available in DOCSIS 1.1 and DOCSIS 2.0 cable networks. This MIB was published as an Internet Draft, Data Over Cable System Interface Specification Quality of Service Management Information Base.

The MODULE-IDENTITY for the DOCS-QOS-MIB is docsQosMIB, and its top-level OID is 1.3.6.1.2.1.10.127.7 (iso.org.dod.internet.mgmt.mib-2.transmission.docsIfMIB.docsQosMIB).
