Introduction
This reference guide provides information about the Simple Network Management Protocol (SNMP) Management
Information Base (MIB) which is applicable for Dell OpenManage Version 7.
NOTE: This guide contains information that may also be applicable to earlier OpenManage supported platforms.
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.
Supported SNMP Versions
Operating System Supported OMSA SNMP version
Windows SNMP v1
Linux SNMP v1
Introduction to the SNMP Reference Guide
This reference guide provides a formatted version of the following Management Information Base that are released with
the current version of Dell OpenManage.
Sections in this guide follow MIB groups and provide explanations and definitions for the terms used to define MIB
objects. Content in this reference guide is organized as documented in the following subsections.
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. The below table describes each Server Administrator Instrumentation MIB group and
lists the MIB group number assigned to the MIB group. The Server Administrator Instrumentation MIB groups are

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
15
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 behaves 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
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.

Tables
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 difference 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 objects used to form lists and tables. When a MIB group is divided into one or more
table
discrete tables, the word
Universal Unique Identifier (UUID). The UUID object has a type and a value that uniquely identifies 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.

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:
17
1. BIOS Setup Control Group — This section explains the purpose of the MIB group and summarizes the major
features of the component groups.
2. BIOS Group Tables — If there is more than one SNMP table for a group, this section lists all of the tables. For this
BIOS group example, there are eight tables listed. In each section, double-clicking any table on the list takes you to
that table.
– BIOS Setup Control Table
– SCSI Control Table
– Parallel Port Control Table
– Serial Port Control Table
– USB Control Table
– IDE Control Table
– Diskette Control Table
– Network Interface Control Table
3. Variables that make up each table in the group — This section documents the variables for the eight tables that
comprise the BIOS group.
4. BIOS Variable Values — This section explains any Server Administrator-specific variables and data types that are
used in this section. In the BIOS group example, there are 17 unique, Server Administrator-specific variable
meanings. Information on each Server Administrator-specific variable is presented in a formatted table.

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
18
events in a MIB. SMIv1 is specified in Request For Comments (RFC) 1155. The Server Administrator MIB conforms to the
SMIv1 standard.
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.
Management Information Base Object Identifiers
Each data class within a Management Information Base (MIB) is defined by an Object Identifier (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.
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:
Table 14. ROOT
CCITT(0)
ISO(1)
ORG(3)
DOD(6)

INTERNET(1)
MGMT(2)
MIB(1)
EXPERIMENTA
L(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. As 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.
NOTE: The default SNMP agent configuration usually includes a SNMP community name such as public. For
security reasons, change the SNMP community names from their default values. For information about changing
SNMP community names, see the
Support website at dell.com/support/manuals. For additional guidelines, see the Securing an SNMP Environment
article, dated May 2003, in the Dell Power Solutions magazine. This magazine is also available at dell.com/
powersolutions .
NOTE: Server Administrator provides support to enable or disable SNMP Set operations. For more information on
enabling or disabling SNMP Set operations in Server Administrator, see the
Administrator User’s Guide
the Dell Support web site at dell.com/support/manuals.
Dell OpenManage Server Administrator User’s Guide

Dell OpenManage Server
or the
Dell OpenManage Server Administrator Command Line Interface User's Guide
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, 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 the 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 Instrumentation Service, see Instrumentation Traps. For
information on Server Administrator Storage Management traps, see Storage Management Alert Reference.
For a list of traps supported by the Remote Access Controller, see RAC Traps, BMC Traps and iDRAC7 Traps.

Systems Management Software Group
The Systems Management Software Group allows users to see information about the standards and software that are
supported by the agent of a particular managed computer chassis. The Systems Management Software Group classifies
each computer chassis according to the systems management standard that the agent supports.
Additional objects define the universal resource locator (URL) of the systems management software and the language in
which systems management information displays. Defining these objects enables users to manage a system using an
internet browser. You can access Server Administrator using the secure hypertext transfer protocol (https) and a preassigned port number of 1311, or you can specify a port number of your own choosing.
NOTE: Using the Software → Server Preferences menu of Server Administrator, you can bind to either one IP
address or to all IP addresses.
To manage a system locally using Server Administrator, type the following in the address field of your browser: https://
localhost:<1311 or
To manage a system remotely using Server Administrator, type one of the following in the address field of your browser:
https://<systemname>:<1311 or
