Preface
Revised: December 2007, OL-4952-08
This guide describes the implementation of the Simple Network Management Protocol (SNMP) for Cisco Cable Modem Termination System (CMTS) routers.
SNMP provides a set of commands for setting and retrieving the values of operating parameters on the router. Router information is stored in a virtual storage area called a Management Information Base (MIB), which contains many objects that describe router components and provides information about the status of the components and network status or events.
This Preface provides an overview of this guide with the following sections:

August 2007 |
Description of Changes
Cisco RF Switch Firmware Version 3.80, installed on the Cisco RF Switch, supports the following changes or enhancements for SNMP MIBs on the Cisco RF Switch, to be used with Cisco IOS release 12.3BC on the Cisco CMTS:
•SNMP MIB get and set variables can be saved to cache in the AdminState MIB module. The SNMP Cache can be disabled or reenabled using the system-level set snmp cache firmware command. The setting for this command is stored in non-volatile memory on the Cisco RF Switch.
•Cisco RF Switch Firmware Version 3.80 adds a new MIB object identifier (OID) to control caching on the Cisco CMTS. To control caching in this manner, use the SNMP object nruCacheSnmpData, which is a read/write integer at OID 1.3.6.1.4.1.6804.2.1.1.9.
•Three system-level Cisco RF Switch firmware commands have been introduced or enhanced to reflect these additional caching functions and options:
–set snmp cache
–show config
–show module
Refer to the following document on Cisco.com for additional command information:

OL-4952-05 |
February 2007 |
Description of Changes
•CISCO-CABLE-WIDEBAND-MIB support on the Cisco uBR10012 universal broadband router. Cisco Wideband Protocol supports downstream wideband channels consisting of multiple bonded RF channels.
Note CISCO-CABLE-WIDEBAND-MIB support is only on the uBR100012 CMTS router and is a Cisco proprietary MIB that supports the DOCSIS 3.0 standard.
–Updated the ENTITY-MIB with the new wideband shared port adapter card, SPA-24XWBD-SFP support, OID 1.3.6.1.4.1.9.12.3.1.9.2.145. See Cisco uBR100012 SPA-24XWBD-SFP Shared Port Adapter, page 72 for the shared port adapter physical entities and values in the ENTITY-MIB.
–Update the IF-MIB for interface wideband management support.
–Added ccwbFiberNodeTable which provides configuration and topology information for Fiber nodes. See CISCO-CABLE-WIDEBAND-MIB, page 16.
–Updated Cisco SNMP Notifications, page 3 with wideband cable trap support.
•Enhanced the CISCO-DOCS-EXT-MIB, page 26 with new table objects that can query both CM and CPE information.
•Added tables (docsQosParamSetEntry, docsQosServiceFlowEntry, docsQosServiceFlowStatsEntry, docsQosPHSEntry, docsQosPktClassEntry, docsQosUpstreamStatsEntry) to support SNMP enhancements in the DOCS-QOS-MIB. This enhancement significantly improves QoS MIB query time in a large scale system with much less CPU consumption.
•Enhanced CISCO-CABLE-SPECTRUM-MIB, page 14 with new tables and objects to support the retrieval of spectrum group information using SNMP query.
•Updated Cisco CMTS platform support for unique device identifier (UDI) compliance. Added support for the unique device identifier (UDI) standard which displays information from any Cisco product that has electronically stored identity information. See Overview of the ENTITY-MIB, page 73.
•Updated the CISCO-CABLE-METERING-MIB with the ccmtrCollectionSrcIfIndex object which is used to specify the source interface for billing packets.
•Added the docsIfCmtsChannelUtilizationInterval object to the DOCS-IF-MIB. This object provides operators with a mechanism to evaluate the load/utilization of both upstream and downstream physical channels. This information may be used for capacity planning and incident analysis, and may be particularly helpful in provisioning of high value QOS.
•Added support on the uBR10012and uBR7246VXR router platforms for the CISCO-CABLE-ADMISSION-CTRL-MIB

July 2006 |
Description of Changes
•Added the DOCS-DSG-IF-MIB, page 62.
•Added cable traps, Cable MIB Notifications, page 21.
•Added section describing the DOSCS-DSG-IF-MIB validation capabilities. See, DOCS-DSG-IF-MIB Validation Requirements, page 41.
•The CISCO-ENHANCED-MEMPOOL-MIB is supported on cable line cards.
•Added cable device traps. SeeCable MIB Notifications, page 21.
•DOCS-IF-MIB, page 58 is updated to draft-ietf-ipcdn-docs-rfmibv2-05.txt.
•IF-MIB, page 79 supports subinterfaces in the ifTable.
•Updated the CISCO-DOCS-EXT-MIB, page 26 for the Dynamic Shared Secret feature.

Description of Changes
•Added table (Table 3-2 on page 6) of cable-specific MIBs.
•Added Appendix C, CMTS MIBs Supported in Cisco IOS Release 12.1(20)EC and IOS Release 12.3(9a)BC—Tables list MIBs supported for past releases for the following universal broadband routers:
–Cisco uBR7100 series and Cisco uBR7200 series for Cisco IOS Release 12.1(20)EC
–Cisco uBR7100 series and Cisco uBR7200 series for Cisco IOS Release 12.3(9a)BC
–Cisco uBR10012 for Cisco IOS Release 12.3(9a)BC
•Updated the following MIBs:
–CISCO-CLASS-BASED-QOS-MIB—This MIB is now supported on the Cisco uBR10012 router
–CISCO-DOCS-EXT-MIB—Supports the dynamic shared secret (DMIC) feature which ensures that every online cable modem uses the DOCSIS configuration file assigned to it. This protects against theft-of-service attempts from subscribers and safeguards operators against stolen or fraudulently downloaded configuration files.
–CISCO-ENTITY-VENDORTYPE-OID-MIB—Updated OIDs.
–CISCO-CABLE-SPECTRUM-MIB notifications. See Cable MIB Notifications, page 21.
–DOCS-QOS-MIB—MIB object information is updated to support DCC for load balancing.
•Updated Chapter 4, "Monitoring Notifications"—Added the following information:
–Brief description—What the event indicates
–Probable cause—What might have caused the notification
–Recommended action—Recommendation as to what should be done when the particular notification occurs
•Added the usage-based billing support feature to section, Usage-Based Billing, page 36. This feature was introduced on Cisco uBR7246VXR and Cisco uBR10012 universal broadband routers.
Feature support includes the new CISCO-CABLE-METERING-MIB, which contains objects that provide subscriber account and billing information in the Subscriber Account Management Interface Specification (SAMIS) format
