DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network management system, and more particularly, to a method for managing the state of a device that is not managed.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional network management system includes a manager unit 2, a network component 6 which is a device to be managed, and network components 6 to 6.
It comprises an agent unit 21 for collecting alarms of the line 9 between the devices 7 not to be managed.

When the agent unit 21 receives an alarm from the network component 6 and the line 9, the alarm is converted into a data format used in the network management system, notified to the manager unit 2, and the manager unit 2 responds to the alarm. Was performed.

When the line is disconnected, the network component 6 notifies the network management system of a line failure alarm as a line abnormality. Moreover, not only the abnormality of the line itself but also the power ON / OFF of the unmanaged device
Thus, even when the power state changes, it is determined that the line state has been switched, and the network management system is notified of a line failure alarm.

[0005]

In the above-described conventional network management system, when an agent receives an alarm from a device to be managed, the agent notifies the manager of the alarm. Since the power ON / OFF of an unmanaged device that is not originally an alarm is also notified as an alarm of a line that is a managed device, the agent unit notifies the manager unit of the alarm, and a line failure occurs in the network management system. Deciding.

For this reason, the user of the network management system is required to make a “failure in the line itself” and “
"OFF" cannot be distinguished / handled. In operation, since the power ON / OFF of the unmanaged device is intensively performed every day at a certain time, if this is all notified and reflected as an alarm to the network management system, the load on the system becomes enormous. There is a problem that other processes are also affected.

[0007]

A first invention is an OSI tube.

To the line connecting the device and the unmanaged device.
The line status changes from ON to OFF when an alarm occurs
The switching station information table,
The unmanaged device corresponding to the line number of the line in
Only when the switching station state is the open state indicating the operating state
The management unit that notifies the manager unit of the alarm;
An elephant device agent unit is provided.

In a second aspect of the present invention, when the alarm of the line occurs, only the alarm whose state of the line has changed from ON to OFF is set in the switching station information table. The apparatus further comprises the managed device agent unit that notifies the manager unit when the switching station state is the open state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

A network management system 1 is a manager unit 2 for performing network management in accordance with the OSI management protocol.
And the unmanaged device agent unit 3 that collects the open / closed (operating / non-operating) status of the unmanaged device 7 and stores the switching station status in the switching station information table 5, and the network as the managed device. It is composed of a managed device agent unit 4 that collects the status of constituent devices 6 and lines 9 and alarms and suppresses alarms that are notified to the manager unit 2 based on the switching station status of the unmanaged device 7 in the switching station information table 5. ing.

There are a plurality of unmanaged devices 7 and lines 9 in one-to-one correspondence. The non-managed device 7 has a non-managed device number 8 and the line 9 has a line number 10.

The switching station information table 5 holds the data of the unmanaged device number 8, the line number 10, and the switching station status 11 for the unmanaged device.

The power supply of the unmanaged device 7 is turned on or off.
In the case of switching to F, a station opening or station closing notification is sent to the unmanaged device agent unit 3. The unmanaged device agent unit 3 selects the switching station status 11 in the switching station table 5 using the unmanaged device number 8 as a key to open the station.
Or rewrite to the closed state .

The power supply of the device 7 to be unmanaged is turned on or turned off.
By switching to F, or the alarm line 9 is notified to the management target device agent unit 4 through the network component device 6, the managed device agent 4
Is, met alarm line status has changed from ON to OFF
Corresponding to line number 10 in switching station information table 5
The alarm of the line 9 is notified to the manager unit 2 only when the switching station state 11 to be opened is the station opening state . Otherwise, all alarms on the line 9 are discarded.

[0016]

As described above, according to the present invention, among the line alarms, the alarms generated when the power of the non-managed device is turned on / off are suppressed by the managed device agent from notifying the manager unit. Power on / off of unmanaged devices to notify the manager only
The FF has the effect of not imposing a load on the manager unit, which is the core of the network management system.
