CHANGE
1.3.6.1.2.1.47.2.0.1 entConfigChange entity.mib 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
