Abstract

An SNMP proxy agent includes a format conversion unit for converting management information received from a monitored device not using the SNMP as a management protocol, into a format corresponding to the SNMP, an IP address conversion unit for converting the particular information on the monitored device included in the management information into a virtual IP address indicating the monitored device, a trap generation unit for generating an SNMP trap having the virtual IP address set as a transmission origin and containing the management information after the conversion, and a transmission unit for transmitting the generated SNMP trap to an SNMP manager.

Claims

1. An SNMP (Simple Network Management Protocol) proxy agent, comprising:

a unit converting specific information of a monitored device which does not employ an SNMP as a management protocol into a virtual IP (Internet Protocol) address indicative of the monitored device; and

a unit generating an SNMP trap message in which the virtual IP address is set to a source address, and which is addressed to an SNMP manager.

3. The SNMP proxy agent according to claim 1, wherein if the trap generating unit receives management information from a monitored device employing the SNMP as a management protocol, the trap generating unit generates a trap message in which an IP address actually allocated to the monitored device is set to a source address.

4. The SNMP proxy agent according to claim 1, wherein if a version of the SNMP corresponding to the monitored device is a version 1, the trap generating unit sets the virtual IP address as control information to an agent address section in a trap format of the SNMP version 1.

5. The SNMP proxy agent according to claim 1, wherein if a version of the SNMP corresponding to the monitored device is a version 2, the trap generating unit sets the virtual IP address as control information to a data main body section in a trap format of the SNMP version 2 as an object.

6. The SNMP proxy agent according to claim 1, wherein if a version of the SNMP corresponding to the monitored device is a version 2, the trap generating unit sets the virtual IP address as control information to a data main body section in a trap format of the SNMP version 3 as an object.

2. An SNMP (Simple Network Management Protocol) proxy agent, comprising:

a format converting unit converting management information received from a monitored device which does not employ the SNMP as a management protocol into management information having a format according to the SNMP;

an IP (Internet Protocol) address converting unit converting specific information of the monitored device included in the management information into a virtual IP address indicative of the monitored device;

a trap generation unit generating an SNMP trap message in which the virtual IP address is set to a source address, and which includes the converted management information; and

a transmission unit transmitting the generated SNMP trap message to an SNMP manager.

7. A method of relaying management information from a monitored device to be managed by an SNMP (Simple Network Management Protocol) manager, the method being executed by an SNMP proxy agent and comprising:

converting management information received from a monitored device which does not employ an SNMP as a management protocol into management information having a format according to the SNMP;

converting specific information of the monitored device included in the management information into a virtual IP address indicative of the monitored device;

generating an SNMP trap message in which the virtual IP address is set to a source address, and which includes the converted management information; and

transmitting the generated SNMP trap message to the SNMP manager.
