Abstract

In a network device and a network management device managing the network device, network management processors of the network devices transmit management information of their own devices in a format displayable on the browser, e.g. XML or HTML upon occurrence of a predetermined event, and a network management processor of the network management device displays the management information.

Claims

1. A network device comprising:

a network management processor for preparing management information of its own device in a format displayable on a browser upon occurrence of a predetermined event; and

a transmitter for transmitting the management information.

2. The network device as claimed in claim 1 wherein the network management processor comprises a management information storage for holding the management information and a management information generator for generating management information of a format displayable on the browser based on the management information.

3. The network device as claimed in claim 1 wherein the format displayable on the browser comprises an HTML or an XML.

4. The network device as claimed in claim 1 wherein an attribute is added to the management information.

5. The network device as claimed in claim 1 wherein the occurrence of the predetermined event comprises at least one of a time of a startup, a time of a management information change, or a predetermined period.

6. The network device as claimed in claim 1 wherein the occurrence of the predetermined event comprises a time when a management information request packet is received from a network management device.

7. A network management device comprising:

a receiver for receiving management information of a format displayable on a browser transmitted from a network device upon occurrence of a predetermined event; and

a network management processor for displaying the management information.

8. The network management device as claimed in claim 7 wherein the network management processor has a management information storage for storing received management information of the format and a management information processor for displaying management information based on the management information.

9. The network management device as claimed in claim 7 wherein the network management processor generates a management information request packet requesting management information determined to be necessary and transmits the packet to the network device.

10. The network management device as claimed in claim 8, further comprising a management information generator for transmitting a management information request packet requesting the management information to the network device, when subsequent management information is not received from the network device after the management information of the network device is received and a predetermined time elapses.

11. The network management device as claimed in claim 8 wherein the management information processor displays each management information from a plurality of network devices respectively on a window screen corresponding to each network device.

12. The network management device as claimed in claim 8 wherein the management information processor displays the management information based on an attribute added to the management information of the format.
