Port: High Alarm: Low Alarm: High Warning: Low Warning: LAG: Displays the port number. This is the highest threshold for the alarm. When the operating parameter rises above this value, action associated with the alarm will be taken. This is the lowest threshold for the alarm. When the operating parameter falls below this value, action associated with the alarm will be taken. This is the highest threshold for the warning. When the operating parameter rises above this value, action associated with the warning will be taken. This is the lowest threshold for the warning. When the operating parameter falls below this value, action associated with the warning will be taken.
