appnPortOperStateChangeTrap

When it has been enabled, this notification makes it possible
for an APPN topology application to get asynchronous
notifications of port operational state changes, and thus to
reduce the frequency with which it polls for these changes.
This notification is only sent when a appnPortOperState has
transitioned to a value of 'active' or 'inactive'.
          
This notification is sent whenever there is a appnPortOperState
object transition to 'inactive' or 'active' state in the
appnPortTable.  This notification is only sent for row creation
if the row is created with a value of 'active' for
appnPortOperState.  This notification is only sent for
row deletion if the last value of appnPortOperState was
'active'.  In this case, the value of appnPortOperState
          
in the notification shall be 'inactive', since the deletion of
a row indicates that the port is no longer active.
          
The notification is more than a simple 'poll me now' indication.
It carries both a count of port table changes, and the
operational state itself.  The count of changes allows an
application to detect lost notifications, either when polling
or upon receiving a subsequent notification, at which point
it knows it must retrieve the entire appnPortTable again.
          
Generation of this notification is controlled by the
appnTrapControl object.
