Description

  The present invention relates to a configuration information management apparatus.

  When a new network or device is connected to a network device represented by a router or a switch, it is necessary to change configuration information set in the network device. As a method for changing the configuration information, there are, for example, a method of inputting a command from an input terminal connected to a network device, and a method of overwriting and copying previously created configuration information created in advance.

  Here, when changing the configuration information by inputting a command, it is necessary to input the command after transitioning to the input mode corresponding to each command. Examples of the input mode include a global configuration mode, an interface configuration mode, and a router configuration mode. In global configuration mode, commands for setting items related to the entire network device such as host names and passwords are input. In interface configuration mode, commands for setting items related to interfaces such as IP addresses are input, and router configuration In the mode, a command for setting a routing protocol or the like is input. Examples of routing protocols include BGP (Border Gateway Protocol), OSPF (Open Shortest Path First), and IGRP (Interior Gateway Routing Protocol).

The technology related to the configuration information input mode is disclosed, for example, in Non-Patent Document 1 below.

Setting items can be classified and output for each input mode. That is, the setting items classified for each input mode can be output as a difference between two generations of configuration information. Thereby, it becomes possible to provide the setting items classified for each input mode as difference information to an operator who is responsible for changing the configuration information set in the network device. In addition, when a signal requesting that an input command corresponding to the output setting item is input to the network device is received, the input command and a mode transition command for shifting to the input mode corresponding to the input command are transmitted to the network. It can be applied to the equipment. As a result, the input command corresponding to the setting item selected by the operator can be input after changing to the input mode for inputting the input command. Therefore, the operator can reliably change the configuration information without being aware of the input mode.

  In the configuration information management device of the present invention, the configuration information management device further includes a difference notification unit that notifies a difference between the two generations of configuration information extracted by the difference extraction unit, and the difference classification output unit classifies the difference between the two generations of configuration information.

  Hereinafter, an embodiment of a configuration information management apparatus according to the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a system configuration of a configuration information management system in the embodiment. As shown in FIG. 1, a configuration information management system 1 includes a configuration information management device 10 that manages configuration information, an input terminal 20 that transmits various requests to the configuration information management device 10, and a known router that is a network device. 30.

  The configuration information management device 10 manages multiple generations of configuration information in each of the routers 30a and 30b, and is registered in the router 30 by inputting commands to the router 30 based on various requests received from the input terminal 20. It is a server device that updates the config information.

  Here, the data structure of the configuration information database 18 will be described with reference to FIG. The configuration information database 18 includes, as data items, for example, an identification ID, newly set configuration information, currently set configuration information, and previously set configuration information. In the identification ID, an ID for uniquely identifying the router 30 is stored. The newly set configuration information stores configuration information that is scheduled to be changed for the router 30 in the future. The configuration information currently set in the router 30 is stored in the configuration information currently set. In the configuration information set in the past, the configuration information set in the past in the router 30 is stored as history information. Therefore, for example, the configuration information set at the time of shipment of the router 30 is stored as the oldest configuration information.

  The configuration information will be described with reference to FIG. As shown in FIG. 4, the configuration information is represented by a hierarchical structure. First, the configuration information includes, for example, global configuration information, interface configuration information, and router configuration information as an upper layer. The interface configuration information exists for each interface provided in the router 30, and the router configuration information exists for each routing protocol.

  As shown in FIG. 4, the global configuration information includes setting items such as a host name and a password. The interface configuration information includes setting items such as an address, validation, and communication speed. Further, the router configuration information includes setting items such as a routing protocol, for example.

  The configuration information thus configured is changed in the following manner. For example, when changing the password A setting in the global configuration information shown in FIG. 4, first enter a mode transition command to change the input mode to the global configuration mode, and then change the password A setting. Input the command to be executed. For example, when the setting of the interface configuration information validation B shown in FIG. 4 is changed, first, a mode transition command is input to change the input mode to the interface configuration mode, and then the validation B Input command to change the setting. Furthermore, for example, when changing the setting of the routing protocol C in the router configuration information shown in FIG. 4, first, a mode transition command is input to change the input mode to the router configuration mode, and then the routing protocol C. Input command to change the setting.

  The input / output control unit 11 illustrated in FIG. 2 sends each request to the configuration information extracting unit 12, the difference extracting unit 13, the difference classifying unit 14, and the command issuing unit 15 when receiving various request signals received from the input terminal 20. The process corresponding to is executed, and the execution result is transmitted to the input terminal 20 or the router 30. Specifically, the input / output control unit 11 executes the following processing.

  The input / output control unit 11 receives from the input terminal 20 a configuration information output request signal requesting to output configuration information in a predetermined router 30. The input / output control unit 11 transmits to the input terminal 20 two-generation configuration information (explained later) extracted by the configuration information extraction unit 12.

  Further, the input / output control unit 11 receives a difference notification request signal for requesting notification of the difference between the two generations of configuration information from the input terminal 20 and notifies the difference extraction unit 13 of the difference notification request signal. The input / output control unit 11 notifies the input terminal 20 of the difference extracted by the difference extraction unit 13.

  Further, the input / output control unit 11 receives a difference classification request signal for requesting to classify and output the difference from the input terminal 20 and notifies the difference classification unit 14 of the difference classification request signal. The input / output control unit 11 transmits the difference classified by the difference classification unit 14 to the input terminal 20.

  Further, the input / output control unit 11 receives a command input request signal for requesting the router 30 to input an input command corresponding to the difference from the input terminal 20 and notifies the command issuing unit 15 of the command input request signal. The input / output control unit 11 transmits the command issued by the command issuing unit 15 to the router 30.

  Further, when receiving a response result to the command transmitted to the router 30, the input / output control unit 11 transmits the response result to the input terminal 20 and notifies the configuration information update unit 16.

  When the input / output control unit 11 receives a configuration information output request signal, the configuration information extraction unit 12 refers to the configuration information database 18 based on the identification ID of the router 30 included in the configuration information output request signal. Then, newly set configuration information corresponding to this identification ID and currently set configuration information are extracted. That is, the configuration information extraction unit 12 extracts two generations of configuration information including the currently set configuration information.

  When a difference notification request signal is received by the input / output control unit 11, the difference extraction unit 13 extracts a difference between both configuration information based on the newly set configuration information and the currently set configuration information. To do. Specifically, setting items whose contents are changed are extracted as differences.

  When the difference classification request signal is received by the input / output control unit 11, the difference classifying unit 14 sets the setting items of the configuration information included in the difference for each input mode for inputting an input command corresponding to the setting item. Classify into:

  When a command input request signal is received by the input / output control unit 11, the command issuing unit 15 receives an input command corresponding to a setting item included in the difference and a mode transition command for shifting to an input mode corresponding to the input command. And issue.

  The configuration information update unit 16 updates the configuration information database 18 when the content of the response result received by the input / output control unit 11 indicates that the command has been normally input. More specifically, the currently set config information is additionally registered in the past set config information as one piece of history information, and the newly set config information is added to the currently set config information. Overwrite and update information.

  Next, the operation of the configuration information management system 1 in this embodiment will be described with reference to FIG. This operation is an operation example performed when the connection terminal 40 is newly connected to the router 30a.

  First, in accordance with the operator's operation instruction, the input terminal 20 transmits a configuration information output request signal for requesting to output the configuration information of the router 30a whose configuration information is to be changed to the configuration information management apparatus 10 (step) S1). As a result, the input / output control unit 11 of the configuration information management apparatus 10 receives the configuration information output request signal.

  Next, the configuration information extraction unit 12 of the configuration information management apparatus 10 refers to the configuration information database 18 based on the identification ID of the router 30a, and newly set configuration information corresponding to this identification ID and the currently set configuration information. The configuration information is extracted (step S2).

  Next, the input / output control unit 11 of the configuration information management apparatus 10 transmits the two generations of configuration information extracted by the configuration information extraction unit 12 to the input terminal 20 (step S3). Thereby, two generations of configuration information is displayed on the display of the input terminal 20 (step S4).

  Next, in accordance with the operator's operation instruction, the input terminal 20 transmits a difference notification request signal for requesting notification of the difference between the two generations of configuration information to the configuration information management apparatus 10 (step S5). As a result, the input / output control unit 11 of the configuration information management apparatus 10 receives the difference notification request signal.

  Next, the difference extraction unit 13 of the configuration information management apparatus 10 extracts a setting item that is a difference between the two pieces of configuration information based on the two generations of configuration information (step S6).

  Next, the input / output control unit 11 of the configuration information management apparatus 10 notifies the input terminal 20 of the setting item that is the difference extracted by the difference extraction unit 13 (step S7). Thereby, the setting item part to be changed among the newly set configuration information displayed on the display of the input terminal 20 is displayed, for example, in red (step S8). For example, when the setting item that is the difference is the activation B shown in FIG. 4, the activation character is displayed in red.

  Next, according to the operator's operation instruction, the input terminal 20 transmits a difference classification request signal for requesting to classify and output the differences displayed in red to the configuration information management apparatus 10 (step S9). As a result, the input / output control unit 11 of the configuration information management apparatus 10 receives the difference classification request signal.

  Next, the difference classification unit 14 of the configuration information management apparatus 10 classifies and outputs the setting items that are differences for each input mode for inputting an input command corresponding to the setting items (step S10). For example, when the setting item that is the difference is the validation B shown in FIG. 4, this validation is classified as information belonging to the interface configuration information.

  Next, the input / output control unit 11 of the configuration information management apparatus 10 transmits the setting items classified for each input mode by the difference classification unit 14 to the input terminal 20 (step S11). Thereby, the setting item classified for each input mode is displayed on the display of the input terminal 20 as the classified difference (step S12).

  Next, when any setting item is selected from the setting items that are the differences classified for each input mode in accordance with the operation instruction of the operator (step S13), the input terminal 20 selects the selected setting item. A command input request signal for requesting the input command corresponding to the item to be input to the router 30a is transmitted to the configuration information management apparatus 10 (step S14). As a result, the input / output control unit 11 of the configuration information management apparatus 10 receives the command input request signal.

  Next, the command issuing unit 15 of the configuration information management apparatus 10 issues an input command corresponding to the setting item selected by the operator and a mode transition command corresponding to this input command (step S15). For example, when the setting item selected by the operator is validation B shown in FIG. 4, an input command corresponding to this validation and a mode transition command for transitioning to the interface configuration mode are issued.

  Next, the input / output control unit 11 of the configuration information management device 10 transmits the input command and the mode transition command issued by the command issuing unit 15 to the router 30a (step S16). As a result, first, a mode transition command is input to the router 30a to change the input mode, and thereafter, the input command is input to update the contents of the configuration information set in the router 30a (step S17). .

  Next, the router 30a transmits a response result to the input command that has been input to the configuration information management apparatus 10 (step S18).

  Next, when receiving a response result to the command transmitted to the router 30a, the input / output control unit 11 of the configuration information management apparatus 10 transmits the response result to the input terminal 20 (step S19). Thereby, the response result is displayed on the display of the input terminal 20 (step S20).

  Here, each process from step S14 to step S20 described above is repeated until the input command input request corresponding to all the setting items that are the differences is completed.

  Then, input command input requests corresponding to all setting items that are differences are received, and all of the response results for each input command transmitted to the input terminal 20 indicate that the input command has been input normally. In the case of the content shown, the configuration information update unit 16 of the configuration information management apparatus 10 updates the configuration information database 18 (step S21).

  In addition, it is good also as omitting each process of step S3-S5 and S7-S9 mentioned above. That is, when the configuration information output request signal transmitted from the input terminal 20 is received in step S1, the configuration information management apparatus 10 extracts the two generations of configuration information (step S2). The process of extracting the difference (step S6) and the process of classifying the setting items for each input mode (step S10) may be continuously performed, and the setting items classified for each input mode may be transmitted to the input terminal 20. . As a result, the configuration information can be changed quickly, and the work efficiency can be improved.

  However, the second generation configuration information is transmitted to the input terminal 20 in step S3, and the operator confirms the second generation configuration information by displaying the second generation configuration information on the display of the input terminal 20 in step S4. Thus, since it is possible to request to notify the difference (step S5), it is possible to advance the process after confirming in advance the configuration information to be changed. In addition, the operator is notified by notifying the input terminal 20 of the setting item that is the difference in step S7 and displaying the configuration information that displays the setting item that is the difference in color on the display of the input terminal 20 in step S8. After confirming which part of the two generations of configuration information is to be changed, it can be requested to classify the differences (step S9), so that the change operation can be executed more reliably. .

  As described above, according to the configuration information management apparatus 10, for example, when a configuration information output request signal for requesting to output configuration information in the router 30a is received from the input terminal 20, two generations of configuration information in the router 30a. And the setting items of the configuration information included in the difference can be classified for each input mode and displayed on the input terminal 20. That is, the setting items classified for each input mode can be output as a difference between two generations of configuration information. Thereby, it becomes possible to provide the setting items classified for each input mode as difference information to an operator who is responsible for changing the configuration information set in the router 30a. Further, when a command input request signal for requesting that the input command corresponding to the output setting item is input to the router 30a is received from the input terminal 20, the input command and the mode transition command corresponding to the input command are received. Can be input to the router 30a. As a result, the input command corresponding to the setting item selected by the operator can be input after changing to the input mode for inputting the input command. Therefore, the operator can reliably change the configuration information of the router 30a without being aware of the input mode.

  In the above-described embodiment, the case where the currently set configuration information is changed to the newly set configuration information has been described. However, the configuration information is not limited to this. For example, the present invention can also be applied when changing currently set configuration information to previously set configuration information. The configuration information extraction unit 12 in this modification refers to the configuration information database 18 based on the identification ID of the router 30 included in the configuration information output request signal, and the configuration information set in the past corresponding to this identification ID. The configuration information currently set may be extracted. That is, the configuration information extraction unit 12 in this modification extracts two generations of configuration information including the currently set configuration information. If the processing after extracting the second generation configuration information is to change the configuration information of the router 30 to the past configuration information based on the difference between the two generations of configuration information, as in the above-described embodiment. Good. As a result, the setting items extracted as the differences can be canceled while being checked item by item, so that it is possible to reliably return the configuration information of the router 30 to the past configuration information. Therefore, it is possible to reliably change the currently set configuration information to the previously set configuration information without being aware of the input mode. In addition, when requesting output of configuration information from the input terminal 20 to the configuration information management apparatus 10, it is also possible to specify which generation of configuration information is used to change the currently set configuration information. As a result, the currently set configuration information can be easily changed to the generation of configuration information designated by the operator.

  Further, in the above-described embodiment, the input terminal 20 is used as a device that transmits various requests to the configuration information management device 10. However, the present invention is not limited to this. For example, the configuration information management device 10 A console may be used.

  In the above-described embodiment, the router 30 is used as a network device. However, the present invention is not limited to this. For example, a switching router or a multilayer switch may be used.
