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
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.
