[RHEL 5.4] 'linkUpDownNotifications' doesn't behave as described in the snmpd.conf man-page

Issue

• "linkUpDownNotifications" doesn't behave as described in the snmpd.conf man-page. The man-page says as follows:

linkUpDownNotifications yes
       will  configure  the Event MIB tables to monitor the ifTable for network interfaces
       being taken up or down, and triggering a linkUp or linkDown notification as  appro-
       priate.

       This is exactly equivalent to the configuration:

              notificationEvent  linkUpTrap    linkUp   ifIndex ifAdminStatus ifOperStatus
              notificationEvent  linkDownTrap  linkDown ifIndex ifAdminStatus ifOperStatus

              monitor  -r 60 -e linkUpTrap   "Generate linkUp" ifOperStatus != 2
              monitor  -r 60 -e linkDownTrap "Generate linkDown" ifOperStatus == 2
