Abstract

A network system automatically distributes management information to allow immediate monitoring. In the network system, the DHCP server of a network-information management server assigns information to a network-information management table when receiving an assignment request of IP information and network management information from a client. The DHCP client of the client obtains the IP information and the network management information from the DHCP server. The SNMP agent of the client reports to a monitoring server that the network management information has been set. The SNMP manager of the monitoring server determines that the network management information has been set, the monitoring control section of the monitoring server records information of the client in a monitoring control table, and starts monitoring the client.

Description

Network system

Technical field

The present invention relates to a kind of network system, particularly be used to carry out the network system that the supervision of the automatic release processing of network management information and the network equipment is handled.

Background technology

Follow popularizing of internet, when the building network of various places, require efficient each network of management.

As the agreement that monitors the equipment that connects network, use SNMP (Simple NetworkManagement Protocol), CMIP (Common Management InformationProtocol), TL1 (Transaction Language 1), HTTP agreement and promoter's agreements alone such as (Hypertext TransferProtocol).Herein, describe as example with the management method of using SNMP.

SNMP is made of proxy server (agent) (SNMP proxy server) that resides in the equipment (client computer, network information management server) as management object and the manager (manager) (snmp management device) that resides in the equipment (monitor server) of a side that manages.The information that exchanges between snmp management device and SNMP proxy server can be divided into the request of obtaining of information and replys the setting request of (Get order), information and reply these three kinds of the notices (Trap) of (Set order), state variation.

In the Get order, carry out information acquisition request to the SNMP proxy server from the snmp management device.The SNMP proxy server obtains information with reference to " management information bank " that be called as " MIB (Management Information Base) ", and replys the snmp management device.In the Set order, set request to the SNMP proxy server from the snmp management device.The SNMP proxy server changes the information of MIB, and the result is replied to the snmp management device.Trap sends to the snmp management device from the SNMP proxy server, the variation of the state of notice SNMP proxy server etc.

When utilizing SNMP to communicate, need carry out source IP and shared name, the access rights of MIB, Trap notify setting to the SNMP proxy server.Source IP sets the IP address of snmp management device usually, uses to the addressee that the snmp management device sends Trap as the SNMP proxy server.Shared name is used for the authentication between snmp management device and the SNMP proxy server.The snmp management device is transmitted shared name when carrying out the Get/Set request to the SNMP proxy server.The SNMP proxy server is checked shared name, if proper shared name is then carried out the operation (Set and Get) that this shared name allows.The access rights of MIB are snmp management device authorities when the MIB of SNMP proxy server conducts interviews, and the Trap notice is set and is used to set the Trap that could send the SNMP proxy server.

About SNMP, on the books in RFC1157.

As the method for the network settings that carries out the next equipment that connects network automatically, use DHCP (Dynamic Host Configuration Protocol) and BOOTP communication protocols such as (BOOTstrapProtocol).Herein, be that example describes with DHCP.

DHCP accept the equipment of set information (DHCP client computer) and set information carried out the monobasic management and to the server (Dynamic Host Configuration Protocol server) of DHCP client computer assignment information between exchange message.Dynamic Host Configuration Protocol server sends the information of IP address, netmask, default gateway etc. to the DHCP client computer from the request of DHCP client computer reception network settings the time.About DHCP, on the books in RFC2131.

In addition, in the method that adopts DHCP, also adopt the technology of obtaining automatically (non-patent literature 3) of the network management information of the use TFTP that has made up TFTP and DHCP.When this method receives the network settings request at Dynamic Host Configuration Protocol server, to the IP address and the deposit position that carries out downloaded files of DHCP client computer notice tftp server.And, after the DHCP client computer is through with the setting of IP address, based on information, from tftp server download network management information from the Dynamic Host Configuration Protocol server notice.

Non-patent literature 1 RFC1157

Non-patent literature 2 RFC2131

Non-patent literature 3 RFC783 (TFTP), RFC2131 (DHCP)

Http:// www.cisco.com/japanese/warp/public/3/jp/service/manual_j/sw/cat30/3550mscg/chapter04/04_swipaddr.html#18750 (CISCOURL information)

As the equipment (client computer or network information management server) of SNMP proxy server when reconnecting network, though can utilize DHCP automatic setting IP information (IP address, netmask, default gateway etc.), can not automatic setting SNMP information (access rights of source IP, shared name, MIB, the setting of Trap notice etc.).

Therefore, generally when the SNMP proxy server is set SNMP information, must manual import operation, in the quantity of SNMP proxy server very for a long time, have the problem of gerentocratic homework burden increase.And, the SNMP proxy server is set SNMP information during, can not monitor by the snmp management device, even problem that can not detection failure information when existing the SNMP proxy server to produce fault.

In SNMP, default value as shared name is set at " public ", when under the state of this setting, connecting network, terminal beyond the snmp management device also can conduct interviews, and has the problem that may carry out wrongful parameter setting and obtain performance information, structural information wrongly.In addition, " public " this shared name does not have the meaning of asterisk wildcard (wide card), if the SNMP client computer is " public ", then the SNMP server also needs to be set at " public ".

In in the past combination in the technology of TFTP and DHCP, except that the DHCP processor, need starting TFTP processor, under the very many situations of the quantity of SNMP proxy server, owing to use the download process of the file of tftp server processor, the load of server rises, and needs to prepare high performance server.And TFTP does not need account and password, and not authenticating fully promptly provides file, thus the fail safe specification extremely thin a little less than.Therefore,, do not want to use TFTP for confidentiality sometimes, have the problem of obtaining automatically that to carry out network management information under this situation according to the difference of server.

Network management information is different because of each SNMP proxy server, so need to prepare to be equivalent to the file of SNMP proxy server quantity in the acquisition methods that adopts TFTP.Therefore, need to prepare to make in addition a plurality of files and the corresponding guide look file of SNMP proxy server, manage very difficulty very for a long time in the quantity of SNMP proxy server.And, also have the risk of file allocation being given other SNMP proxy servers because of error.

Summary of the invention
