SNMP Reference Guide

22 Introduction
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 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.
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.

These objects comprise the Server Administrator definitions for the UUID.
