Introduction
This introduction is divided into two sections. The first section, "Introduction to the SNMP
Reference Guide," explains the SNMP Reference Guide design. All essential Simple Network
Management Protocol (SNMP) terms are defined in this section. Some of the vocabulary may seem
complex and unfamiliar to system administrators who are using SNMP for the first time.
SNMP experts can skim this section, and beginners can read the section more carefully.
The second section, "Introduction to the Server Administrator SNMP Subagent," is a more technical
introduction to the management information base (MIB) that underlies Server Administrator services.

Server Administrator Instrumentation MIB
The Server Administrator Instrumentation MIB (filename 10892.mib) provides instrumentation data that
allows you to monitor the health of a system with SNMP management applications. It provides:
• Information about the status of temperatures, power supplies, voltages, currents, fans, and memory at
key points in the system
• Rapid access to detailed fault and performance information gathered by industry standard systems
management agents
• Version information for Basic Input/Output System (BIOS), firmware, and operating system
• A detailed account of every cost of ownership (COO) detail about your system
In addition, traps are sent to report a change in status of the health of critical components.
The Server Administrator Instrumentation MIB structures its MIB objects into groups of scalar objects
or MIB tables that provide related information. Table 1-2 describes each Server Administrator
Instrumentation MIB group and lists the MIB group number assigned to the MIB group.
14 Introduction
The Server Administrator Instrumentation MIB groups are identified by the SNMP OID
1.3.6.1.4.1.674.10892.1.<MIB group number>, where <MIB group number> is the MIB group number
assigned to the MIB group. See the relevant section for more information about the MIB objects defined

SNMP Basic Terminology
It is important to have a good understanding of the key technical terms used in this guide. This guide
provides definitions for all essential terms used in describing the Server Administrator MIBs.
The Glossary contains definitions for all essential terms and acronyms.
18 Introduction
SNMP Master Agent
Typically, the SNMP agent on a managed system consists of one SNMP master agent and zero or more SNMP
extension agents. This SNMP agent extendable structure facilitates the addition of new MIB modules
without having to rebuild the entire SNMP agent and is invisible to SNMP management applications.
The SNMP master agent is responsible for receiving SNMP request protocol messages from SNMP management
applications and sending SNMP response protocol messages. As part of processing SNMP request
protocol messages, the SNMP master agent typically communicates with one or more SNMP extension
agents. This communication does not involve standard SNMP protocol messages. The SNMP master
agent uses an extension protocol that shields the SNMP extension agent from the standard SNMP
protocol messages. The extension protocol also provides a way for SNMP extension agents to send SNMP
event notifications (called traps in SNMPv1). The SNMP master agent is also responsible for sending
SNMP event notification protocol messages to SNMP management applications.
On supported operating systems, the SNMP master agent is provided with the operating system.
For example, on supported Microsoft
®
Windows® operating systems, the Windows SNMP service is the
SNMP master agent. For information on the versions of the SNMP protocol supported by the SNMP
master agent, see the operating system documentation.
SNMP Extension Agent
The SNMP extension agent is responsible for registering the MIB objects that it supports with the
SNMP master agent and then processing requests from the SNMP master agent for those MIB objects.
The SNMP extension agent also initiates event notifications to the SNMP master agent. The SNMP
extension agent does not receive or send standard SNMP protocol messages. The SNMP extension agent
communicates with the SNMP master agent using an extension protocol defined by the SNMP master agent.
The Server Administrator SNMP subagent is an SNMP extension agent.
Managed Object
A managed object is any item in a computer system that can be singled out for discovery, monitoring,
or user intervention and correction.
NOTE: Not all managed objects described in this guide are supported by all systems.
MIB
A MIB acts as a structured road map for managed objects. As an Application Programming Interface
(API), a MIB allows systems management tools to retrieve data maintained by an agent. The server
administrator MIB is divided into several major groups of managed objects.
Introduction 19
Variable
A variable is a component of a managed object. A temperature probe, for example, has a variable to
describe its capabilities, its health or status, and certain indexes that you can use to locate specific
temperature probes. One index for the probe would be the probe’s chassis number. Some systems may
have multiple chassis—one chassis for the central processing unit and another chassis for storage.
A chassis within a system can also have more than one temperature probe. Variables for a temperature
probe include its capabilities, status, chassis index, and index.
One-Based Index
When an index is one-based, counting starts at 1. One-based indexing counts the first instance as 1,
the second index as 2, and so on.
Zero-Based Index
When an index is zero-based, counting starts at 0. Zero-based indexing counts the first instance as 0,
the second index as 1, and so on.
Fields
Managed object variables contain fields. In this reference guide, managed object variables have the
following fields defined:
Name is the exact string by which the variable is known in the MIB. MIB variables are named according
to the following conventions:
• Variable names start with a lowercase letter.
• Spaces are not allowed between words in the variable name.
• Acronyms are in uppercase letters, except when an acronym is the first word in the variable name.
• With the exception of the first letter of the variable name and acronyms, all other words in the variable
name start with capital letters.
The following variable names illustrate these conventions:
temperatureProbeLowerCriticalThreshold
coolingUnitIndex
pCIDeviceSpeed
Object Identifier (OID) is the unique number assigned to an object defined in a MIB. An OID is
written as a sequence of subidentifiers in decimal notation. Each OID in this reference guide has a prefix
that identifies the managed objects as belonging to Dell™: 1.3.6.1.4.1.674. The additional numbers
identify the MIB group and subgroup as well as the table entry number of any variables.
20 Introduction
For example, the OID for the temperature probe managed object table is 700.20 and the variable for the
location of the temperature probe (temperatureProbeLocationName) has an OID of 700.20.1.8. The full
OIDs for these items are 1.3.6.1.4.1.674.10892.1.700.20 for the temperatureProbeTable and
1.3.6.1.4.1.674.10892.1.700.20.1.8 for the temperatureProbeLocation. For more information about the
structure of OIDs, see "SNMP MIB OIDs."
Description is a brief explanation of what a particular managed object does.
Syntax defines the data type in which the values of the variable must be expressed. Most variables in this
reference guide use standard data types such as string or boolean. All data types that are unique to server
administrator variables are defined at the end of the section in which they occur. Standard data types are
defined in "Standard Data Type Definitions."
Access specifies whether persons with administrative privileges can read but not modify the value of a
variable (read only) or can both read and modify the value of a variable (read-write).
Frequently Used Terms in Variable Names
The following terms are frequently used in the name of a MIB variable:
Capability refers to the actions an object can perform, or to actions that can be taken by the object.
Hot-pluggable is an example of a capability. If a card is hot-pluggable, it can be replaced while a system is
running. Capability settings refer to the capabilities of the object that the user can select from and
activate if desired. Capability settings allow users of the server administrator to predetermine how an
object will behave under specific conditions.
Settings are the conditions of a manageable object that determine what happens when a certain value is
detected in a component. For example, a user can set the upper critical threshold of a temperature probe
to 75 degrees Celsius. If the probe reaches that temperature, the setting causes an alert to be sent to the
management console. Some settings, when reached, can trigger a system shutdown or other response to
prevent damage to the system.
State refers to the condition of an object that has more than one condition. For example, an object may
be in a "not ready" or in an "enabled" state.
Status refers to the health of an object or how the object is functioning. For example, the status of a
temperature probe that is measuring acceptable temperatures would be reported as normal. When the
probe begins reading temperatures that exceed limits set by the user, it reports a critical status.
Tabl es
This reference guide contains two types of tables: tables that are used to organize and define variable
values and tables that define MIB objects. Readers must understand the differences between these
two types of tables.
SNMP Tables
Most of the MIB objects defined in this reference guide are organized into SNMP tables. SNMP tables
organize data into two-dimensional structural arrays. In SNMP, objects that have a relationship to other
objects are called columnar objects. Columnar objects are the type of object used to form lists and tables.
Introduction 21
When a MIB group is divided into one or more discrete tables, the word "table" has a technical meaning.
An example is the section of this reference guide entitled Universal Unique Identifier (UUID).
The UUID object has a type and a value that uniquely identify an object such as a chassis. The table
defines all of the variables that comprise the managed object UUID.
The following table is an example of an SNMP table. The table contains variables that must occur in a
definite sequence. In the example table the defined variables are UUID Chassis Index, UUID Index,
UUID Type, and UUID Value.

Reference Guide Content Tables
NOTE: Variable values are defined for any variable that is Server Administrator-specific. Industry-standard
variable definitions are documented in "Standard Data Type Definitions."
Some of the tables in this guide have no technical significance in SNMP. These tables are designed to show
information in a readable form. The following table, for example, defines the Server Administrator-specific
variable, DellFanControlCapabilities. The table provides the name of the variable, its data type,
the values that are valid for the variable, and the meaning of each value.
Introduction 23
Table 1-8. Example Variable Type Definition Table
Variable Name: DellFanControlCapabilities
Data Type: Integer
Possible Data Values Meaning of Data Value
unknown(1) The fan’s capabilities are unknown.
lowSpeedCapable(2) The fan can be set to low speed.
highSpeedCapable(4) The fan can be set to high speed.
lowOrHighSpeedCapable(6) The fan can be set to low or high speed.
This type of table is used throughout the reference guide to list and define variable values. Tables that
explain Server Administrator-specific variable values are located in the final section of sections that
define Server Administrator-specific variables. In the preceding example, the variable name is
DellFanControlCapabilities. This variable must be expressed as an integer and has four possible values:
unknown, lowSpeedCapable, highSpeedCapable, and lowOrHighSpeed Capable.
Section Organization
Sections in this reference guide are based on the Server Administrator MIBs, so the complexity of each
section depends on the complexity of each MIB group. The first section provides a high-level
introduction to the MIB group. If the group is defined by one or more tables, the second section lists
these tables. The third section documents the variables that comprise the group, and if applicable,
the variables that comprise the tables. The fourth section contains definitions for any Server
Administrator-specific variables that are used in the section. The following example shows the typical
content of these four sections.

Introduction to the Server Administrator SNMP Subagent
This guide provides formatted information drawn primarily from the MIB files written for the
Server Administrator services that support the SNMP protocol.
For each of the variables defined in the MIBs, the following fields are specified:
• Variable name
• OID or unique identifying number
•Description
• Data type of the variable (for example: integer, string, octet string)
• Whether the variable is accessible, not accessible, read-only, or read-write
• Index or indexes, if applicable
For each MIB group that has unique variable definitions, tables are included in the last section of the
section to explain the meaning of the terms.
Standards for writing MIBs are defined by the Internet Engineering Task Force (IETF). Structure of
Management Information (SMI) is a standard that specifies the rules for defining the structure and type
of managed objects and events in a MIB. SMIv1 is specified in Request For Comments (RFC) 1155.
The Server Administrator MIB conforms to the SMIv1 standard.
Introduction 25
SNMP is a systems management standard originally designed for network management. SNMP manages
much more than networks. Information Technology (IT) professionals use SNMP for monitoring and
managing computer systems and the various components and peripherals supported by their systems.
SNMP standards are defined by the Internet Engineering Task Force (IETF). SNMP version 1 was
published in August 1988 and is the most commonly supported version of SNMP. SNMP version 2 was
first published in May 1993, but has not gained widespread market acceptance. SNMP version 3 was
recently completed and has addressed security issues that exist in version 1.
All SNMP systems consist of one or more managed systems that provide data through an SNMP agent to
a management system. The management system provides a user interface to view data from the
managed systems. The management system and managed systems communicate over a network
(typically through User Datagram Protocol/Internet Protocol [UDP/IP]).
The management system and a managed system communicate by means of a common data schema.
SNMP MIB files define the structure, type, and values of the SNMP data. While MIBs can be
standardized or enterprise specific, most operating systems supply SNMP agents for the standard MIB-I
and MIB-II schemas. MIB-I defines a base set of standard management information for systems
implementing the Internet Protocol (IP) suite. MIB-II defines characteristics of the system,
characteristics of network interfaces, and characteristics of components of the IP on the system.
In addition to the standard MIBs, many hardware vendors have defined MIBs that provide management
data specific to their systems and peripheral devices.
Monitored data can be retrieved through SNMP using the Get command. Typically, this command
requires the host name or IP address of the target machine as well as the OID of the data to retrieve.
Exact details are dependent on the operating system and the development tools being used to create the
management application. The Get command has a variant known as GetNext.
SNMP MIB OIDs
Each data class within an MIB is defined by an OID. OIDs are unique across all MIBs. An OID consists
of a series of digits separated by periods. The OID functions in a similar fashion to a phone number.
The phone number 011-512-471-0000 uniquely identifies a single phone. The phone number can be broken
down into a number of components to uniquely identify a phone. The first component, 011, is the
country code for the United States. The second component, 512, identifies the area code for central Texas.
The third component, 471, is the phone exchange for a large state university in the city of Austin.
The final component, 0000, is the main switchboard.
There are two main differences between the phone number example and an actual OID. The first
difference is that there are many more components in an OID, up to 128. The combination of these
components is called an OID prefix. The second difference is that OIDs support the concept of indexes
or keys. The OID prefix specifies the data class but does not specify an instance of the data within the class.
Indexes can be used to identify the instances of a data class. These indexes are referred to as the OID suffix.
26 Introduction
The assignment of values for each OID prefix component can be illustrated by using a tree structure.
The following is an example of an OID assignment:
ROOT
CCITT(0)
ISO(1)
ORG(3)
DOD(6)
INTERNET(1)
MGMT(2)
MIB(1)
EXPERIMENTAL(3)
PRIVATE(4)
ENTERPRISES(1)
DELL(674)
SNMPv2(6)
In the preceding example, the OID prefix for the Dell enterprise would be 1.3.6.1.4.1.674.
The numbers in boldface type show the categories and numbers that apply to Server Administrator.
All Server Administrator-defined OIDs consist of 1.3.6.1.4.1.674 followed by additional component values.
SNMP Security
SNMP version 1 has a very limited security mechanism. SNMP agents support the use of a community
string, which is configured at each SNMP agent and is passed as a part of all SNMP request messages.
There is no verification that the requester is actually a member of the specified community.
Because most system and network management data is not confidential, this limited security is
acceptable for Get types of requests. On the other hand, this security is not acceptable for Set types of
operations where an SNMP request could power off a system, reconfigure a redundant array of
independent disks (RAID) card, and so on. Some vendors have chosen not to support SNMP Set
operations for this reason. Server Administrator is able to support SNMP Set operations because its
SNMP agents implement a hash/digest mechanism to prevent unauthorized SNMP Set operations.
One limitation of this practice is that only server administrator-developed SNMP management
applications have the capability to support the hash/digest mechanism.
Introduction 27
Initiating Management Actions
Management actions can be performed using the SNMP Set command. These actions can consist of
configuring a phone number for the system’s owner, rebooting a system, or changing the asset tag of the
system. See the previous section, "SNMP Security," for limitations on Set operations.
SNMP Traps
SNMP is frequently used to monitor systems for fault conditions such as temperature violations,
hard drive failures, and so on. Management applications can monitor for these conditions by polling the
appropriate OIDs with the Get command and analyzing the returned data. This method has its
drawbacks. If it is done frequently, significant amounts of network bandwidth can be consumed. If it is
done infrequently, the response to the fault condition may not occur in a timely fashion. SNMP traps
avoid these limitations of the polling method.
An SNMP trap is an asynchronous event indicating that something significant has occurred. This is
analogous to a pager receiving an important message, except that he SNMP trap frequently contains all
the information needed to diagnose a fault.
Two drawbacks to SNMP traps are that they are sent using UDP, which is not a guaranteed delivery
mechanism, and that they are not acknowledged by the receiver.
An SNMP trap message contains the trap’s enterprise OID, the agent IP address, a generic trap ID, the
specific trap ID, a time stamp, and zero or more variable bindings (varbinds). The combination of an
enterprise OID and a specific trap ID uniquely identifies each Server Administrator-defined trap.
A varbind consists of an OID and its value and provides additional information about the trap.
In order for a management system to receive SNMP traps from a managed system, the node must be
configured to send traps to the management system. Trap destination configuration is dependent on the
operating system. When this configuration is done, a management application on the management
system can wait for traps and act on them when received.
For a list of traps supported by the server administrator SNMP subagent, see "Traps."

Instrumentation MIB Version Group
The Instrumentation Management Information Base (MIB) Version Group defines the attributes
that identify the version of the Instrumentation MIB supported by the systems
management software.
The mIBMajorVersionNumber, mIBMinorVersionNumber, and mIBMaintenanceVersionNumber
attributes are scalar objects, meaning that they are not related to other MIB objects and are thus not
placed in a table.
MIB Major Version Number
Name mIBMajorVersionNumber
Object ID 1.3.6.1.4.1.674.10892.1.1.1.0
Description Defines the major version number of the version of this MIB
supported by the systems management software. For example, if the
MIB version is 1.2.3, the major version number is 1.
A major version number change indicates a major change in object
functionality.
