Chapter 1 Overview

Management Information Base

CAR provides e-mail alerts for various events, including the following events:

• Charge Limit Notification indicates when the daily charge limit for a user exceeds the specified

maximum.

• QoS Notification indicates when the percentage of good calls drops below a specified range or the

percentage of poor calls exceeds a specified limit.

For more information, refer to the Cisco Unified Communications Manager CDR Analysis and

Reporting Administration Guide.

Management Information Base

The Management Information Base (MIB) converts object identifiers (OIDs) that are numerical strings

into an ASCII text file. The OIDs identify data objects. The OID represents specific characteristics of a

device or application and can have one or more object instances (variables). Managed objects, alarms,

notifications, and other valuable information get identified by the OID and get listed in the MIB.

The OID gets logically represented in a tree hierarchy. The root of the tree stays unnamed and splits into

three main branches—Consultative Committee for International Telegraph and Telephone (CCITT),

International Organization for Standardization (ISO), and joint ISO/CCITT.

These branches and those that fall below each category have short text strings and integers to identify

them. Text strings describe object names, while integers allow computer software to create compact,

encoded representations of the names. For example, the Cisco MIB variable authAddr represents an

object name and gets denoted by the number 5, which is listed at the end of OID 1.3.6.1.4.1.9.2.1.5.

The OID in the Internet MIB hierarchy represents the sequence of numeric labels on the nodes along a

path from the root to the object. The OID 1.3.6.1.2.1 represents the Internet standard MIB. It also can

get expressed as iso.org.dod.internet.mgmt.mib.

The Cisco MIB set comprises a collection of variables that are private extensions to the Internet standard

MIB II and many other Internet standard MIBs. RFC 1213, Management Information Base for Network

Management of TCP/IP-based Internets—MIB-II documents MIB II.

Cisco Unified CM and Cisco Unified CMBE support the following MIBs:

• CISCO-CCM-MIB

• CISCO-CCM-CAPABILITY

• CISCO-CDP-MIB

• CISCO-SYSLOG-MIB

• HOST-RESOURCES-MIB

• MIB-II

• SYSAPPL-MIB

• Vendor-specific MIBs

For descriptions of the supported MIBs, see the following chapters:

• Chapter 7, “Cisco Management Information Base”

• Chapter 8, “Industry-Standard Management Information Base”

• Chapter 9, “Vendor-Specific Management Information Base”
