When a primary failure occurs, each agent device (information processing device) checks itself to determine whether non-notification setting has been performed for alarm notification of the primary failure. If no non-notification setting has been performed, the agent device sends the alarm notification to a manager device (network management device). At the same time, the agent device sends a set alarm mask request to the agent device located downstream in the signal flow to request to perform non-notification setting for alarm notification of a secondary failure caused by the primary failure.
