    STATUS    current
    DESCRIPTION
        "The code that describes the type of alert for this entry in

        the table.  Binary change event alerts describe states of the
        subunit while unary change event alerts describe a single
        event.  The same alert code can be used for a binary change
        event or a unary change event, depending on implementation.
        Also, the same alert code can be used to indicate a critical
        or non-critical (warning) alert, depending on implementation.
        The value of prtAlertSeverityLevel specifies binary vs. unary
        and critical vs. non-critical for each event for the
        implementation.

        While there are some specific codes for many subunits, the
        generic codes should be used for most subunit alerts.  The
        network management station can then query the subunit
        specified by prtAlertGroup to determine further subunit
        status and other subunit information.

        An agent shall not add two entries to the alert table for the
        same event, one containing a generic event code and the other
        containing a specific event code; the agent shall add only
        one entry in the alert table for each event; either generic
        (preferred) or specific, not both.

        Implementation of the unary change event
        alertRemovalOfBinaryChangeEntry(1801) is optional.  When
        implemented, this alert code shall indicate to network
        management stations that the trailing edge of a binary change
        event has occurred and the corresponding alert entry has been
        removed from the alert table.  As with all events, the
        alertRemovalOfBinaryChangeEntry(1801) alert shall be placed
        at the end of the alert table.  Such an alert table entry
        shall specify the following information:

        prtAlertSeverityLevel   warningUnaryChangeEvent(4)
        prtAlertTrainingLevel   noInterventionRequired(7)
        prtAlertGroup           alert(18)
        prtAlertGroupIndex      the index of the row in the
                                alert table of the binary
                                change event that this event
                                has removed.
        prtAlertLocation        unknown (-2)
        prtAlertCode            alertRemovalOfBinaryChangeEntry(1801)
        prtAlertDescription     <description or null string>
        prtAlertTime            the value of sysUpTime at
                                the time of the removal of the
                                binary change event from the
                                alert table.

        Optionally, the agent may generate a trap coincident with

        removing the binary change event and placing the unary change
        event alertRemovalOfBinaryChangeEntry(1801) in the alert
        table.  For such a trap, the prtAlertIndex sent with the above
        trap parameters shall be the index of the
        alertRemovalOfBinaryChangeEvent row that was added to the
        prtAlertTable; not the index of the row that was removed from
        the prtAlertTable."
