prtAlertIndex

The index value used to determine which alerts have been added
or removed from the alert table.  This is an incrementing
integer initialized to 1 when the printer is reset.  (i.e., The
first event placed in the alert table after a reset of the
printer shall have an index value of 1.)  When the printer adds
an alert to the table, that alert is assigned the next higher
integer value from the last item entered into the table.  If
the index value reaches its maximum value, the next index value
used must be 1.
              
NOTE: The management application will read the alert table when
a trap or event notification occurs or at a periodic rate and
then parse the table to determine if any new entries were added
by comparing the last known index value with the current
highest index value.  The management application will then
update its copy of the alert table.  When the printer discovers
that an alert is no longer active, the printer shall remove the
              
row for that alert from the table and shall reduce the number
of rows in the table.  The printer may add or delete any number
of rows from the table at any time.  The management station can
detect when binary change alerts have been deleted by
requesting an attribute of each alert, and noting alerts as
deleted when that retrieval is not possible.  The objects
'prtAlertCriticalEvents'and 'prtAlertAllEvents' in the
'prtGeneralTable' reduce the need for management applications
to scan the 'prtAlertTable'.
              
NOTE: The above description has been modified from RFC 1759
for clarification.
