As the title suggests I am looking to understand what causes traps to be sent out from the entity.mib. The definition is as follows:
entityMIBTraps OBJECT IDENTIFIER ::= { entityMIB 2 }
entityMIBTrapPrefix OBJECT IDENTIFIER ::= { entityMIBTraps 0 }
entConfigChange NOTIFICATION-TYPE
STATUS current
DESCRIPTION
"An entConfigChange notification is generated when the value
of entLastChangeTime changes. It can be utilized by an NMS
to trigger logical/physical entity table maintenance polls.
An agent should not generate more than one entConfigChange
'notification-event' in a given time interval (five seconds
is the suggested default). A 'notification-event' is the
transmission of a single trap or inform PDU to a list of
notification destinations.
If additional configuration changes occur within the
throttling period, then notification-events for these
changes should be suppressed by the agent until the current
throttling period expires. At the end of a throttling
period, one notification-event should be generated if any
configuration changes occurred since the start of the
throttling period. In such a case, another throttling period
is started right away.
An NMS should periodically check the value of
entLastChangeTime to detect any missed entConfigChange
notification-events, e.g., due to throttling or transmission
loss."
::= { entityMIBTrapPrefix 1 }
What I would like to know is what is meant by configuration changes in this case. Is it a configuration change made via the configuration terminal? Just looking to see what causes these traps to be sent out.
