This mib defines the SNMP objects to report
exceptions to north-bound NMS.
        
The devices implementing this MIB monitor 
the status of hardware and software services, and
report any exceptions regarding these components.
These hardware and software services could 
belong to the monitoring devices or other managed
devices. 
        
An exception is something abnormal that the system 
administrators should pay attention to. The criteria
for what is an exception could vary by system
and should be defined by the system administrators.
Certain NM devices or applications may have 
pre-defined exceptions. 
        
This MIB does not try to define exceptions. But 
rather it defines SNMP objects for devices to 
use SNMP notification as an exception reporting 
mechanism. Exceptions may be pre-defined or defined 
through other device management interface such as 
CLI, GUI, or HTTP.
