The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This guide describes the implementation of the Simple Network Management Protocol (SNMP) for the 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). The MIB contains objects that describe router components and provides information about the status of these components.
This preface provides an overview of this guide with the following sections:

The ifIndex object of MIB objects that pointed to the modular or the integrated interfaces now points to the cable interface and RF channels SNMP IF Index of the uBR-MC3GX60V, UBR-MC20X20V and uBR-MC88V line cards, and SPAs. Following are the MIBs and their tables where the ifIndex object points to the RF channel SNMP IF index:

This guide is intended for system and network administrators who must configure the Cisco CMTS Router for operation and monitor its performance in the network.
This guide may also be useful for application developers who are developing management applications for the router.
This guide contains the following chapters:
|
|
---|---|
Provides background information about SNMP and its implementation on Cisco CMTS routers. |
|
Provides instructions for configuring SNMP management support on the router. |
|
Describes each MIB included in the software image. Each description lists any constraints as to how the MIB is implemented on the router. |
|
Describes the SNMP traps and notifications supported by the router. |
|
Chapter B, “Relationship Between MIB Objects and CLI Show Commands” |
Provides a cross-reference between commonly used objects in the MIBs and the related cable-related show commands. |
This section discusses conventions and terminology used in this guide.
Note Many commands use the word traps in the command syntax. Unless there is an option in the command to select either traps or informs, the keyword traps refers to traps, informs, or both. Use the snmp-server host and snmp-server enable notification command to specify whether to send SNMP notifications as traps or informs.
