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 behaves under specic 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.
Tables
This reference guide contains two types of tables: tables that are used to organize and dene variable values and tables that dene MIB
objects. Readers must understand the dierence between these two types of tables.
SNMP Tables
Most of the MIB objects dened 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 discrete tables, the word table has a technical meaning. An example
is the section of this reference guide entitled Universal Unique Identier (UUID). The UUID object has a type and a value that uniquely
identies an object such as a chassis. The table denes 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 denite sequence. In the example
table the dened variables are UUID Chassis Index, UUID Index, UUID Type, and UUID Value.
These objects comprise the Server Administrator denitions for the UUID.
