Abstract
An image forming apparatus is provided. The image forming apparatus includes a network interface unit which is connected to a host device in which a manager program is stored, a printing unit which performs a printing job, a storage unit which stores a management information base (MIB), and an agent program, and a control unit which communicates with the host device using a Simple Network Management Protocol (SNMP). If an application is newly installed, the control unit updates the MIB. Therefore, it is possible to easily add, modify, or delete a management object (MO).
Claims15
An image forming apparatus comprising:
- a network interface unit which is connected to a host device in which a manager program is stored;
- a printing unit which performs a printing job;
- a storage unit which stores information on the image forming apparatus, a management information base (MIB), and an agent program corresponding to the manager program;
- and
- a control unit which communicates with the host device using a Simple Network Management Protocol (SNMP),
- wherein if an application is newly installed, the control unit updates the MIB using an object identifier (01D) of a management object (MO) of the newly installed application, and
- wherein if a request for information designating an OID included in the updated MIB is input from the host device, the control unit transmits information corresponding to the designated OID to the host device by executing an application corresponding to the designated OID using the agent program.
A management system comprising:
- a host device which stores a manager program;
- and
- an image forming apparatus which stores an agent program corresponding to the manager program,
- wherein the image forming apparatus comprises:
- a network interface unit which is connected to a host device;
- a printing unit which performs a printing job;
- a storage unit which stores information on the image forming apparatus, a first management information base (MIB), and the agent program;
- and
- a control unit which communicates with the host device using a Simple Network Management Protocol (SNMP),
- wherein if an application is newly installed, the control unit updates the first MIB using an object identifier (01D) of a management object (MO) which the newly installed application has, and
- if a request for information designating an OID included in the updated first MIB is input from the host device, the control unit transmits information corresponding to the designated OID to the host device by executing an application corresponding to the designated OID using the agent program, and
- wherein the host device has a second MIB individually, transmits a request for information to the image forming apparatus using the second MIB, and receives the information, and
- wherein if the application is newly installed in the image forming apparatus, the host device updates the second MIB using an OID of an MO which the newly installed application has.
An information providing method of an image forming apparatus, the method comprising:
- if an application is newly installed, storing the application;
- updating a management information base (MIB) using an agent program based on an object identifier (01D) of an MO which the application has;
- receiving an information request from a host device in which a manager program corresponding to the agent program is installed, using a Simple Network Management Protocol (SNMP);
- searching the MIB for a management object (MO) designated by the information request;
- and
- providing the host device with information corresponding to the designated MO using an application corresponding to the searched MO from among pre-installed applications.
