This MIB module defines the managed objects that describe the
online diagnostics capabilities supported by the
physical entities contained by the system, including chassis,
modules, ports, power supplies, fans, and sensors.  In order to
manage the online diagnostic capabilities supported by
a physical entity, it must be represented by a conceptual row
in the entPhysicalTable of the ENTITY-MIB (RFC-2737).
        
GLOSSARY
        
Boot-up Diagnostic - a diagnostic consisting of tests intended
to be executed in a reasonable timeframe when a physical entity
boots.
        
Diagnostic - a suite of tests intended to exercise the
functional integrity of a physical entity.
        
Diagnostic Level - the degree of completeness that a diagnostic
will exercise a physical entity.
        
Field Diagnostic - a special suite of tests intended to
exercise the functional integrity of a physical entity in a
manner that is possible when a physical entity is
operational or running an operational image.
        
Field Diagnostic Image - an image supporting field diagnostics.
A physical entity has to be loaded with a field diagnostic
image before field diagnostics can be executed on the physical
entity.
        
Health Monitoring - the process of running special
non-intrusive online tests periodically on a physical entity
for the purpose of tracking the overall condition of a physical
entity.
        
On-Demand Diagnostic - a diagnostic intended to be executed
immediately upon request.
        
Offline Diagnostic - a diagnostic that consists of tests that
are disruptive in nature, and thus requires the physical entity
being evaluated to be taken offline for the duration.
        
Online Diagnostic - a diagnostic that consists of tests that
are not disruptive in nature, and thus can be done without
taking the physical entity offline.
        
Physical Entity - an identifiable physical resource, such as a
chassis, line card, power supply, or communication port.  See
RFC-2737, 'Entity MIB (Version 2)', K. McCloghrie and A.
Bierman.
        
Scheduled Diagnostic - a diagnostic intended to execute at some
time in the future.  There exist two types of scheduled
diagnostics: 1) one-shot, which execute only once; and 2)
periodic, which executes at a specific interval.
        
Test - an exercise intended to determine the functional
integrity of a component comprising a physical entity (e.g., a
port might support an internal loopback test).
        
Diagnostic Job - Consists of a diagnostic suite 
(i.e., a collection of tests) to be executed by a physical
entity.
