Description

  The present invention relates to a technique for creating management information when making settings for various devices in a communication network.

In recent years, devices such as routers and servers constituting a communication network such as an IP (Internet Protocol) network use products of a plurality of vendors. In addition, even the products of the same vendor may have different models and OS (Operating System), and the setting method of these devices is not unified. For this reason, the administrator of the communication network is responsible for what commands are provided for each device vendor, model, and OS in connection with the construction of the communication network (for example, a series of operations for opening a line or maintaining the device). Management information indicating the order of input is prepared, and various settings are performed on the communication network device while referring to the management information (see Non-Patent Document 1).

Selecting a command ID of a command corresponding to an identifier of the input order of the command related to the business, and writing the selected command ID into the business information as a command ID corresponding to the identifier of the input order of the business information This is a configuration setting management model creation method characterized by

  According to such a configuration setting management model creation device (hereinafter referred to as a model creation device), command information (commands that have been entered in each device in the past) It is possible to easily create a configuration setting management model that associates the analysis result of the command response result. Here, the analysis result includes command group information, model-specific command information, and parameter information. In other words, the command input order, command mode and response, command type, model-specific command, parameter part of the command, and parameter type are indicated. By using this configuration setting management model, a predetermined job can be performed. This makes it easier to determine what command should be input and what parameter should be set in which part when setting the parameter.

  According to a second aspect of the present invention, in the configuration setting management model creation device according to the first aspect, the keyword information includes a keyword included in an error message from the device, and the command structure analysis unit responds to each command. When the keyword indicating the error message is included in the response with reference to the keyword information, the command type is determined as an error command, and the input order information regarding the command is not written in the command group information. The information creation unit does not include the information on the command determined to be an error command in the model-specific command information, and the business information management unit displays the input order information as a command ID corresponding to the input order identifier of the command group information. A feature is that a command ID of a command that has not been written is not written.

  In this way, when the configuration setting management model creation device finds an error command in the command information, the command group information can indicate that the type of this command is an error command. In addition, when creating model-specific command information, model-specific command information that does not include an error command can be created. Further, in the command group information, since the information indicating the input order is not written in the error command, the business information management unit skips the error command and writes the command ID corresponding to the identifier of the business information input order. Can do.

  According to a third aspect of the present invention, in the configuration setting management model creation device according to the first or second aspect, the keyword information includes a keyword included in a response instructing a change in a command input order from the device. The command structure analysis unit refers to the response to each command and the keyword information, and when the response includes a keyword for instructing the change of the command input order, the command in which the input order is changed for the command. It is characterized by creating group information.

  By doing in this way, when the configuration setting management model creation device finds a response instructing the change of the order of entry in the command information, it can create command group information in which the order of order is changed. That is, even when the command input order shown in the command information is not correct, command group information can be created by rearranging the commands in the correct input order.

  According to a fourth aspect of the present invention, in the configuration setting management model creation device according to any one of the first to third aspects, the command structure analysis unit performs a structure analysis of the input command information. A command mode transition hierarchy is determined based on a command mode and a response of the command, and command group information including the command mode transition hierarchy is created.

  By doing so, the configuration setting management model creation device can create command group information including a mode transition hierarchy of commands.

  The invention described in claim 6 is a program for causing a configuration setting management model generation apparatus, which is a computer, to execute the configuration setting management model generation method described in claim 5.

  According to such a program, it is possible to cause a general computer to execute the configuration setting management model creation method described in claim 5.

  According to the present invention, it is possible to reduce the trouble of creating a configuration setting management model, which is management information that is referred to when various settings are made for an apparatus.

<Overview>
Hereinafter, the best mode for carrying out the present invention (hereinafter referred to as an embodiment) will be described. First, an outline of a configuration setting management model created by the configuration setting management model creation device of the present embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating a configuration setting management model according to the present embodiment.

  As shown in FIG. 1, the configuration setting management model 134 includes business information 1340, CLI (Command Line Interface) command group information (command group information) 1341, model-specific command information 1342, and parameter information 1343.

  This work information 1340 is input to each device (router or the like) constituting the communication network (for example, IP (Internet Protocol) network) in the construction for each type of communication network (for example, line opening). Information indicating the command input order identifier (for example, the output commands 1, 2, 3, 4, 5, etc. of the business information 1340 in FIG. 1). In the work information 1340 in FIG. 1, the construction A inputs an output command (output commands 1, 2, 3, and 4) marked with a circle for the construction A, and the input order is output command 1 → output command 2 Indicates that the order is output command 3 → output command 4. Also, the construction B inputs an output command (output commands 2, 4, and 5) marked with a circle for the construction B, and the order of the input is the order of the output command 2 → the output command 4 → the output command 5. It shows that.

  The CLI command group information 1341 is information obtained by analyzing a series of command groups (command information) previously input to the apparatus. The CLI command group information 1341 is obtained from the device when the command ID of each command, the command content, the command mode, and the command are input together with the type (model) and construction name of the device to which the command group is input. Response character string (response), command input order, command type (for example, normal command, command for mode transition, error command, etc.), mode transition layer (layer in which the command was input) It is the information which showed etc.

  The model-specific command information 1342 is obtained by arranging the commands shown in the CLI command group information 1341 in the order of input and segmenting the commands. Here, when a parameter is included in this command, information indicating a parameter portion of this command is also included. For example, the model-specific command information 1342 indicates that commands are input in the order of “ID1”, “ID2”, and “ID3”. Further, the command of “ID2” indicates that it is segmented into “interface” and parameters “<a>” and “<b>”. Although not shown here, the model-specific command information 1342 also includes information on the file name and command ID of the CLI command group information 1341 that is the source of information for each command. That is, CLI command group information 1341 and model specific command information 1342 are associated with corresponding commands.

  The parameter information 1343 is information indicating a parameter attribute (parameter type) of each command indicated in the model-specific command information 1342. For example, among the parameters “<a>” and “<b>” of the command “ID2” of the model-specific command information 1342, “<a>” is a character string, and “<b>” is a number. It shows that.

  When receiving the input of command information, the configuration setting management model creating apparatus of the present embodiment first analyzes this command information and creates CLI command group information 1341. Then, model-specific command information 1342 is created based on the created CLI command group information 1341, and then parameter information 1343 is created for the parameters indicated in the model-specific command information 1342.

  Thereafter, the configuration setting management model creation device associates the task information 1340 indicating the output command necessary for the construction with the CLI command group information 1341 for each construction. That is, the CLI command group information 1341 related to the construction is read out from the CLI command group information 1341 file using the construction name of each construction indicated in the business information 1340 as a key. Then, referring to the input order of each command in the CLI command group information 1341, the command ID of the command in the CLI command group information 1341 corresponding to each command (output command) indicated in the business information 1340 is written.

  For example, the command (“ID1”) of the input order “1” of the CLI command group information 1341 of “file A” is used as the command corresponding to the output command 1 (the first input command) of the construction A in the business information 1340 of FIG. Command). Then, the configuration setting management model creation device writes “file A” and the command ID “ID1” of this command in the column of output command 1 of construction A in the business information 1340. Such processing is executed for each construction indicated in the business information 1340. If there is a plurality of models of CLI command group information 1341 for the same construction, command IDs related to the output command are written from the file of CLI command group information 1341 regarding all the models. That is, the file name and command ID of the CLI command group information 1341 relating to the command of each model are written in the output command column for each construction in the business information 1340. In this way, the configuration setting management model 134 is created.

  In this way, the configuration setting management model 134 in which the business information 1340 and the CLI command group information 1341, the CLI command group information 1341, the model-specific command information 1342, the model-specific command information 1342, and the parameter information 1343 are associated with each other is managed by the administrator. And so on as management information, it becomes easy to confirm what commands should be input in what order to each device when performing a predetermined construction.

  In the following description, the CLI command is described as an example, but the present invention is not limited to this. Further, although a case where a model is used as the type of device will be described as an example, the type of device vendor (manufacturer), an OS (Operating System) installed in the device, or a combination thereof may be used.

<Configuration>
Next, the configuration of a configuration setting management model creating apparatus that creates such a configuration setting management model will be described. FIG. 2 is a diagram showing the configuration of the configuration setting management model creation device of the present embodiment.

  As illustrated in FIG. 2, the configuration setting management model creation device 10 includes an input / output unit (input unit, output unit) 11, a processing unit 12, and a storage unit 13.

  The input / output unit 11 includes an input / output interface, and the processing unit 12 is realized by a program execution process by a CPU (Central Processing Unit) included in the configuration setting management model creation device 10 or a dedicated circuit. The storage unit 13 includes a storage medium such as a random access memory (RAM), a read only memory (ROM), a hard disk drive (HDD), and a flash memory. When the configuration setting management model creation device 10 is realized by program execution processing, the storage unit 13 stores a program for realizing the function of the configuration setting management model creation device 10.

  The configuration setting management model creation device 10 includes an input device 200 (for example, a keyboard and a mouse) for inputting various information, and an output device 300 (for outputting information of the configuration setting management model creation device 10). For example, a liquid crystal monitor or the like may be connected.

  The input / output unit 11 receives input of the command information 100 or outputs a processing result by the processing unit 12 to the output device 300. The command information 100 is, for example, information indicating commands actually inputted to the apparatus and various responses in various past works.

  FIG. 3 is a diagram illustrating the command information of FIG. Here, the command information 100 of “ROUTER-A” of model A in the construction A is shown. In FIG. 3, (A1) to (A6) are prompts before command input, (B1) to (B6) are commands, and (C1) to (C6) are prompts after command input. Note that the model name (device type) and construction name of the device to which each command shown in the command information 100 is input and the construction name are input via the input device 200 when the command information 100 is input. Alternatively, the command information 100 may be included in the input.

  The processing unit 12 of FIG. 2 includes a command structure analysis unit 121, a parameter extraction unit 122, an information creation unit 123, a business information management unit 124, and an output processing unit 125.

  The command structure analysis unit 121 analyzes the structure of the input command information 100. That is, the command structure analysis unit 121 analyzes each command indicated in the command information 100 based on prompts before and after the input of the command and keyword information 132 (described later), and inputs each command, the command mode, CLI command group information 1341 (see FIG. 1) indicating the response is created. The CLI command group information 1341 created here is stored in the storage unit 13. Details of the analysis procedure at this time will be described later using a flowchart.

  The parameter extraction unit 122 refers to the command policy information 131 (described later), and determines the command indicated in the CLI command group information 1341, the parameter portion of each command, and the parameter type of the parameter portion.

  FIG. 4 is a diagram conceptually showing processing by the parameter extraction unit of FIG. For example, the parameter extraction unit 122 of FIG. 2 performs “ip”, “address”, “10.10.10.1” for the command “ip address 10.10.10.1 255.255.255.0” shown in the CLI command group information 1341 (see FIG. 1). ”And“ 255.255.255.0 ”. Then, referring to the command policy information 131 for the model (for example, model A) of the CLI command group information 1341, “ip”, “address”, “10.10.10.1”, and “255.255.255.0” are respectively It is determined that they are “model-specific keyword A”, “model-specific keyword B”, “parameter indicating IPv4 (Internet Protocol Version 4) address”, and “parameter indicating IPv4 subnet”.

  2 creates model-specific command information 1342 (see FIG. 1) indicating the command shown in the CLI command group information 1341 and the parameter part of each command based on the determination result of the parameter extraction unit 122. create. In addition, parameter information 1343 indicating the attributes (parameter types) of the parameter parts indicated in the model-specific command information 1342 is created. The information creation unit 123 stores the created model-specific command information 1342 and parameter information 1343 in the storage unit 13.

  For example, based on the determination result by the parameter extraction unit 122 described above, the information creation unit 123 adds the model-specific keyword of the command extracted from the CLI command group information 1341 to the model-specific command information 1342 as shown in FIG. The parts (“ip”, “address”) are written as they are, and “parameters indicating IPv4 address” and “parameters indicating IPv4 subnet” are replaced with “<c>”, “<d>”, and the like, respectively. Then, parameter information 1343 indicating the parameter type (IPv4 address, IPv4 subnet, etc.), the set minimum value and the set maximum value is created for the replaced parameter parts “<c>” and “<d>”.

  When the information creation unit 123 creates the model-specific command information 1342, as shown in FIG. 1, the layer in which the command is input based on the mode transition layer information indicated in the CLI command group information 1341. The identification information may be shown. For example, in the CLI command group information 1341 shown in FIG. 1, since the mode transition hierarchy of the command having the command ID “ID2” is “2”, the description of this command in the model-specific command information 1342 is the “command hierarchy 2” column. May be written to indicate that the command input layer is “command layer 2”.

  The business information management unit 124 in FIG. 2 associates the business information 1340 with the CLI command group information 1341. The work information management unit 124 selects CLI command group information 1341 related to the work for each work (for example, work A and B) indicated in the work information 1340. Next, the business information management unit 124 refers to the input order of each command indicated in the selected CLI command group information 1341, and uses this CLI command group information 1341 to identify the output command identification information (for example, , The command ID of the command (for example, the command of the input order “1”) corresponding to the output command 1 or the like. The selected command ID is written as a command ID corresponding to the input order identifier in the business information 1340. For example, the business information management unit 124 uses a command with the command ID “ID1” in the CLI command group information 1341 of the file “file A” as a command corresponding to “output command 1” of “construction A” of the business information 1340. Write information that there is.

  The output processing unit 125 outputs various types of information included in the configuration setting management model 134 stored in the storage unit 13. For example, when an output request for information related to an output command to the device including the construction name and the model name of the device used for the construction is received via the input / output unit 11, the business information included in the configuration setting management model 134 is received. From 1340, the file name and command ID shown in the column of each output command (output commands 1 to 5) in the construction of this construction name are read out. Then, the output processing unit 125 outputs a command from the CLI command group information 1341 corresponding to the file name and the command ID, and outputs the model-specific command information 1342 information corresponding to the command and the parameter information 1343. To do.

  Next, the storage unit 13 will be described. The storage unit 13 stores command policy information 131, keyword information 132, business information 1340, CLI command group information 1341 created by the processing unit 12, model-specific command information 1342, and parameter information 1343. The business information management unit 124 associates the output information of the business information 1340 with the business information 1340 in which the command ID of each command indicated in the CLI command group information 1341 is associated with the CLI command group associated with the output. The information 1341, the model-specific command information 1342 of the CLI command group information 1341, and the parameter information 1343 are collectively referred to as a configuration setting management model 134.

  The command policy information 131 is information indicating the grammar of the command to be input to the device of the model for each model. FIG. 5A is a diagram illustrating the command policy information of FIG. Here, the command policy information 131 of the device of model A will be described as an example. For example, in the command policy information 131 of the model A shown in FIG. 5A, if the command includes “?”, It is a help command, and if there is a space delimiter, it is “command division (command ) ”. Also. If `` GigaBitEthernet 0/0/0 to 0/0/8 '' or `` POS 1/0/0 to 1/0/8 '' is included, it is a command indicating an interface, and `` 10.10.10.1 to 100.100 If a value of “.100.100” is included, it indicates an IPv4 address. The command policy information 131 is referred to when the command structure analysis unit 121 segments a command, or the parameter extraction unit 122 extracts a parameter from the command and determines the type of the parameter.

  The keyword information 132 in FIG. 2 is information indicating a keyword for determining the type (command type) of each command from the device of the model for each model. FIG. 5B is a diagram illustrating the keyword information in FIG. Here, the keyword information 132 of model A will be described as an example. For example, in the keyword information 132 of the model A shown in FIG. 5B, “%, error, invalid...” Is a keyword for determining an error command, and “before, after,. It is a keyword for determining that replacement is necessary, and “y / n,...” Indicates a keyword for determining an interactive command. The keyword information 132 is referred to when the command structure analysis unit 121 analyzes each command indicated in the command information 100 and creates CLI command group information 1341.

  Next, each element constituting the configuration setting management model 134 will be described.

  The business information 1340 indicates, for each type of communication network construction (for example, line opening, etc.), what commands should be input (output) to each device in that construction in what order. Information. FIG. 6A is a diagram illustrating business information in an initial state, and FIG. 6B is a diagram illustrating business information in a state after linking a file name and a command ID. In the initial state, as illustrated in FIG. 6A, the business information 1340 indicates an output command (see a circle in FIG. 6A) that needs to be input to each device for each construction (business). This information is input to the storage unit 13 in advance by an administrator or the like. Then, when the business information management unit 124 associates the business information 1340 with the command of the CLI command group information 1341, a command corresponding to the output command is described as shown in FIG. 6B. The file name of the CLI command group information 1341 and the command ID of the command are written.

  The CLI command group information 1341 in FIG. 2 is information created by analyzing the command information 100 as described above. The CLI command group information 1341 includes, for example, as shown in FIG. 1, the model of the device in which the command is input, the construction name in which the command is used, the command ID of each command, the command mode of the command, A response character string, input order, command type, mode transition hierarchy, and the like are shown.

  In the model-specific command information 1342 of FIG. 2, the commands shown in the CLI command group information 1341 are arranged in the order of input. If a parameter is included in this command, a parameter portion is also shown. The model-specific command information 1342 indicates, for example, the model name and construction name for which each command is input, and the commands are arranged in the order of input. Then, if the segmented command and a parameter are included in the segmented command, the parameter portion is indicated. Further, as shown in FIG. 1, the model-specific command information 1342 may include information related to a command hierarchy in which each command is input.

  The parameter information 1343 in FIG. 2 indicates the attribute (parameter type) of each parameter of each command indicated in the model-specific command information 1342. As shown in FIG. 1, the parameter information 1343 may include a minimum setting value, a maximum setting value, a default value, and the like for each parameter. By including such information, it is possible to confirm what range of values can be taken and the value to be selected by default when the administrator sets values for each parameter of the command.

<Processing procedure>
Next, the processing procedure of the configuration setting management model creation device will be described with reference to FIG. First, the outline of the processing procedure of the configuration setting management model creation device 10 will be described with reference to FIG. FIG. 7 is a flowchart showing an outline of a processing procedure of the configuration setting management model creation device of FIG. Here, it is assumed that the business information 1340 is input in advance via the input / output unit 11 and stored in the storage unit 13.

  First, the configuration setting management model creation device 10 of FIG. 2 receives input of command information 100 via the input / output unit 11 (S101). Then, the command structure analysis unit 121 analyzes the structure of the command indicated in the input command information 100 and creates CLI command group information 1341 (S102). The created CLI command group information 1341 is stored in the storage unit 13. Next, the parameter extraction unit 122 refers to the command policy information 131 to determine the parameter portion of each command indicated in the CLI command group information 1341 and the parameter type of the parameter portion. The information creation unit 123 Model-specific command information 1342 and parameter information 1343 are created (S103). Then, the business information management unit 124 associates the business information 1340 with the CLI command group information 1341 (S104).

  The creation process of the CLI command group information 1341 in S102 of FIG. 7 will be described in detail with reference to FIG. FIG. 8 is a flowchart showing the creation processing of the CLI command group information in S102 of FIG.

  First, the command structure analysis unit 121 divides the command information 100 (see FIG. 3) into (A) a prompt before command input, (B) command, and (C) prompt after command input (S201). .

For example, the command structure analysis unit 121 includes the command information 100 shown in FIG.
ROUTER-A # configuration terminal
ROUTER-A (config) #
The information
(A1) Prompt before command input: ROUTER-A #
(B1) Command: configuration terminal
(C1) Prompt after command input: ROUTER-A (config) #
Divide into

  Next, the command structure analysis unit 121 determines whether (A) the prompt before command input and (C) the prompt after command input are the same (S202). Here, when the prompt before (A) command input and the prompt after (C) command input are the same (Yes in S202), the command type of this command is determined to be a normal command (S209). Then, the process proceeds to S210. S210 will be described later.

  On the other hand, when (A) the prompt before command input and (C) the prompt after command input are different in S202 (No in S202), the command structure analysis unit 121 determines that the prompt after (C) command input is It is determined whether or not any keyword indicated in the keyword information 132 is included (S203). That is, in S203, the command structure analysis unit 121 selects, from the storage unit 13, the keyword information 132 related to the device having the model name indicated in the command information 100 (for example, the keyword information 132 related to the model A shown in FIG. 5B). (C) It is determined whether or not the prompt after inputting the command includes any of the keywords indicated in the selected keyword information 132.

  Here, when the command structure analysis unit 121 determines that the prompt after the (C) command input includes one of the keywords indicated in the keyword information 132 (Yes in S203), the command structure analysis unit 121 refers to the keyword information 132. Then, it is determined whether the keyword is (D-1) an error command determination keyword, (D-2) an input order determination keyword, or (D-3) an interactive command determination keyword (S204). On the other hand, when it is determined in S203 that the prompt after the input of the command (C) does not include any keyword indicated in the keyword information 132 (No in S203), the command type of this command is determined to be a mode transition command (S205). ), Go to S210.

  For example, in the command information 100 illustrated in FIG. 3, (A1) ROUTER-A # is different from (C1) ROUTER-A (config) #, and (C1) ROUTER-A (config) # is The keyword information 132 is not included. Therefore, the command structure analysis unit 121 determines that the command type of (C1) ROUTER-A (config) # is a mode transition command.

  In S204, when the keyword included in the prompt after (C) command input is (D-1) an error command determination keyword ((D-1) in S204), the command structure analysis unit 121 executes the command of this command. The type is determined as an error command (S206), and the process proceeds to S210. On the other hand, when this keyword is the (D-2) input order determination keyword ((D-2) in S204), it is determined that the input order of this command is to be changed (S207), and the process proceeds to S210. Further, when this keyword is (D-3) an interactive command determination keyword ((D-3) in S204), the command type of this command is determined to be an interactive command (S208), and the process proceeds to S210.

  For example, in the command information 100 illustrated in FIG. 3, (A4) ROUTER-A (config) # is different from (C4)% invalid input detected at '~' marker. Includes the keywords “%” and “invalid” indicated in the error command determination keyword of the keyword information 132 of the model A (see FIG. 5B). Therefore, in S208 of FIG. 8, the command structure analysis unit 121 determines that the command type of (B4) port-range 1000 2000 any is an error command.

  In S210, the command structure analysis unit 121 determines (A) prompt before command input, (B) command, (C) prompt after command input, command type and input order based on the determination results in S205 to S209. Write to the CLI command group information 1341 (see FIG. 1).

  The command structure analysis unit 121 performs the above processing on all commands indicated in the command information 100 (for example, (A1) (B1) (C1), (A2) (B2) ( C2), ..., (A6), (B6), and (C6)), and CLI command group information 1341 is created.

  When the command structure analysis unit 121 writes (A) the prompt before command input in the CLI command group information 1341, for example, (A) the router name portion of the prompt before command input is cut. Is written as the command mode of this command. For example, for (A1) ROUTER-A #, “#” obtained by cutting “ROUTER-A” is written as the command mode. Similarly, when writing the prompt after inputting the command (C) in the CLI command group information 1341, the command structure analysis unit 121 cuts the router name and writes it as a response character string of this command. For example, for (C1) ROUTER-A (config) #, “(config) #” in which “ROUTER-A” is cut is written as a response character string. The command structure analysis unit 121 writes the input order of the CLI command group information 1341 in accordance with the input order of the commands indicated in the command information 100, but the error command does not write the input order and starts from the next command. Write the input order. That is, the error command is skipped and written. For commands for which it is determined in S207 that a change in the order of input is necessary, the input order is changed and written.

  The CLI command group information obtained by analyzing the command information 100 in FIG. 3 by the processing as described above becomes the CLI command group information 1341 (file A) shown in FIG. FIG. 9 is a diagram illustrating CLI command group information created based on the command information of FIG. As described above, the CLI command group information 1341 indicates, for each command ID, the command, command mode, response character string (response), input order, command type, mode transition hierarchy, and the like of the command information 100. As described above, in the CLI command group information 1341, the error command (“ID4” command) is skipped in the input order, and the input command number is written from the next command (“ID5” command). .

  In the processing described above, the command structure analysis unit 121 determines that the command type is a mode transition command when (A) the prompt before command input is different from (C) the prompt after command input. Based on the reason.

  FIGS. 10A and 10B are diagrams for explaining the concept of mode transition according to the present embodiment. For example, as shown in FIG. 10A, when a “login / passed” command is input from the login mode to the device, the mode is shifted to the user mode, and a response “>” is obtained from the device. Next, when an “enable” command is input to the device, the mode is changed to the privileged mode, and a response “#” is obtained from the device. Subsequently, when the “c” command is input to the device, the mode is shifted to the configuration mode, and a response “(config) #” is obtained from this device. From here, the sub-configuration mode is entered. At this time, the “interface...” Command is input to shift to the sub-configuration mode related to the interface (sub-configuration mode (interface)). A response “(if-config) #” is obtained from this device. From here, it is possible to shift to a sub-configuration mode (sub-configuration mode (routing)) related to routing by inputting a predetermined command.

  FIG. 10B is a diagram exemplifying a command input and a prompt indicating a response in the transition of each mode indicated by reference numeral 1001 in FIG. As shown in FIG. 10B, a prompt (“(config) #”) indicating a response after the command A (“configuration terminal”) is input and a command B (“interface TenGig 1/0/0”) Unlike the prompt “(if-config) #” that indicates the response after the command is input, the prompt “(if-config) #” that indicates the response after the command C (“description AAA”) is input, This is different from the prompt “(config) #” indicating a response after the command D (“exit”) is input. Therefore, the commands A and D are determined as mode transition commands. In addition, a prompt “(if-configure) #” indicating a response after inputting command B (“interface TenGig 1/0/0”) and a response after inputting command C (“description AAA”) are shown. Since it is the same as the prompt “(if-config) #”, it is determined that the command is not a mode transition command.

  As shown in FIG. 10A, such a mode transition is also performed when a hierarchy for inputting commands is changed, such as a configuration mode → a subconfiguration mode (interface). It is also performed when transitioning to another mode in the same hierarchy, such as (interface) → sub-configuration mode (routing). Here, whether or not the mode has been changed to another layer is determined by the content of the prompt indicating the response after the command is input. For example, when the prompt changes from "#" to "(config) #", or from "(config) #" to "(if-config) #", it is determined that the transition has been made to another level. . On the other hand, when the prompt changes from “(if-config) #” to “(router) #”, it is determined that the mode has changed in the same hierarchy. The mode transition hierarchy determined in this way is written in the CLI command group information 1341 by the command structure analysis unit 121. That is, the administrator or the like refers to the command mode, mode transition hierarchy, and command type of each command in the CLI command group information 1341, so that each command has a hierarchical structure as shown in FIG. It is also possible to grasp to which hierarchy each command is input.

  Next, the creation processing of the model-specific command information 1342 and the parameter information 1343 in S103 of FIG. 7 will be described in detail with reference to FIG. FIG. 11 is a flowchart showing the model-specific command information and parameter information creation processing in S103 of FIG.

  First, the parameter extraction unit 122 of FIG. 2 refers to the command policy information 131 and segments (decomposes) each command of the CLI command group information 1341 (S301). For example, when the target CLI command group information 1341 is the CLI command group information 1341 related to the model A, the parameter extraction unit 122 refers to the command policy information 131 related to the model A (see FIG. 5A). , Segment each command by space-separated parts.

  Next, the parameter extraction unit 122 refers to the command policy information 131 and extracts the parameter part of the segmented command (S302). Each element of the segmented command, the parameter part of the command, the parameter part thereof Is determined, and model-specific command information 1342 and parameter information 1343 are created (S303). The created model-specific command information 1342 and parameter information 1343 are stored in the storage unit 13.

  For example, the parameter extraction unit 122 segments the command “ip address 10.10.10.1 255.255.255.0” illustrated in FIG. 4 into “ip”, “address”, “10.10.10.1”, and “255.255.255.0”. Then, referring to the command policy information 131, “ip”, “address”, “10.10.10.1”, “255.255.255.0” are respectively “model-specific keyword A”, “model-specific keyword B”, “IPv4”. (Internet Protocol Version 4) “parameter indicating address” and “parameter indicating IPv4 subnet”. Next, as shown in FIG. 1, the parameter extraction unit 122 converts “ip” and “address” and subsequent parameter portions “10.10.10.1” and “255.255.255.0” into “<c>”. ”And“ <d> ”to create model-specific command information 1342. Then, parameter information 1343 indicating the parameter type is created for “<c>” and “<d>” which are parameter portions.

  The parameter extraction unit 122 executes such processing for each command indicated in the CLI command group information 1341, and creates model-specific command information 1342 and parameter information 1343 related to the CLI command group information 1341.

  Next, the process of associating the business information 1340 and the CLI command group information 1341 in S104 of FIG. 7 will be described using FIG. FIG. 12 is a flowchart showing the process of associating the business information with the CLI command group information in S104 of FIG.

  The business information management unit 124 in FIG. 2 selects CLI command group information 1341 related to the construction for each construction indicated in the business information 1340 (S401).

  For example, when the construction indicated in the business information 1340 is construction A, the CLI command group information 1341 related to the construction A is selected from the storage unit 13. Here, when the CLI command group information 1341 related to the construction A is for a plurality of models, all the CLI command group information 1341 is selected.

  The business information 1340 selects a command corresponding to the output command of the construction with reference to the input order of each command indicated in the CLI command group information 1341 selected in S401 (S402).

  For example, in the business information 1340 shown in FIG. 1, the output command for the construction A is the output commands 1, 2, 3, and 4. Therefore, the business information 1340 includes the CLI command group information 1341 (“file A”) regarding the construction A. As the output command 1, the command of the input order “1” of the “file A” is selected. Similarly, as the output command 2, a command in the input order “2” is selected, and as the output command 3, a command in the input order “3” is selected. Such selection is executed up to the output command 4. However, a command whose command type is “error command” indicated in the CLI command group information 1341 is not selected here.

  In the business information 1340 shown in FIG. 1, the output command for the construction B is the output commands 2, 4, and 5. Therefore, the business information management unit 124 uses the CLI command group information 1341 (“file B”) regarding the construction B to As the output command 2, the command of the input order “2” is selected, as the output command 4, the command of the input order “4” is selected, and as the output command 5, the command of the input order “5” is selected.

  Then, the business information management unit 124 stores the command selected in S402 as an output command in the work of the business information 1340 (S403).

  For example, the business information management unit 124 writes “file A, ID1” to the output command 1 and outputs “file A, ID1” to the output command 2 for the output command 1, 2, 3, 4 of the construction information A 1340. "A, ID2" is written, "File A, ID3" is written for the output command 3, and "File A, ID5" is written for the output command 4 (Skip because "ID4" is an error command). The business information management unit 124 writes the file name (“file B”) of the CLI command group information 1341 corresponding to each of the output commands 2, 4, and 5 and the command ID for the construction B of the business information 1340.

  In this way, the business information management unit 124 associates the business information 1340 with each command of the CLI command group information 1341. In other words, the business information management unit 124 uses a command ID of a command (input order “1”, “2”, “3”, etc.) corresponding to an identifier of the input order of commands (for example, output commands 1, 2, 3,. Is selected from the CLI command group information 1341, and the selected command ID is written as a command ID corresponding to the identifier of the input order in the business information 1340. As described above, each command of the CLI command group information 1341 of the configuration setting management model 134 is associated with the model-specific command information 1342, and each parameter of the model-specific command information 1342 is associated with the parameter information 1343. It has been. Therefore, for example, the administrator or the like refers to the configuration setting management model 134 to determine which command in the CLI command group information 1341 corresponds to the output command of each work in the business information 1340, and parameters of the command. This makes it easy to check the section and the parameter type of the parameter. The business information management unit 124 may directly associate each output command of the business information 1340 with the command of the model-specific command information 1342 corresponding to this output command.

  In the above-described embodiment, the configuration setting management model creation apparatus 10 creates the parameter information 1343 for each model-specific command information 1342. However, the present invention is not limited to this. For example, the parameter information 1343 may be shared by a plurality of model specific command information 1342. For example, for the parameter type of each parameter part indicated in the model-specific command information 1342 determined by the parameter extraction unit 122, the information creation unit 123 adds any ID of the existing parameter information 1343 to the model-specific command information 1342. Whether information should be referred to may be written.

  In addition, the configuration setting management model creation device 10 analyzes what command is followed by the command determined to be an interactive command among the commands indicated in the CLI command group information 1341, and displays the dialog. Information related to a command having a high correlation with the type command may be included in the CLI command group information 1341. By doing so, it becomes easier to confirm what command should be input to prevent an error following the interactive command.

  Further, the parameter extraction unit 122 determines the parameter type, the maximum value and the minimum value that can be set from the response character string to the help command (for example, “?”) Of each command indicated in the CLI command group information 1341. Or a character string may be extracted, and the extracted information may be reflected in the command policy information 131. By doing in this way, the parameter extraction part 122 can create the command policy information 131 regarding various models.

  Further, when the parameter extraction unit 122 determines the type of each command indicated in the CLI command group information 1341, the parameter extraction unit 122 is common to a parameter unit that sets a unique value for each device and a communication network (network) including the device. It is also possible to identify a parameter part for setting various parameters and write the information in the parameter information 1343.

  Further, associating the CLI command group information 1341 and the model-specific command information 1342, the model-specific command information 1342 having the same command as the command shown in the CLI command group information 1341 may be searched and linked. The parameter information 1343 may be searched for and associated with the parameter type of the parameter of the model-specific command information 1342. That is, the configuration setting management model creation apparatus 10 may create CLI command group information 1341, model-specific command information 1342, and parameter information 1343, and link these pieces of information later.

  In addition, the business information 1340 and the CLI command group information 1341 are linked by writing the file name of the CLI command group information 1341 and the command ID of the command in the output command column of the business information 1340. It is not limited to. For example, if the command ID is unique to each command in the CLI command group information 1341, the file name may be omitted and only the command ID may be written.

  The configuration setting management model creation device 10 according to the present embodiment can be realized by a program that executes the processing as described above, and stores the program in a computer-readable storage medium (CD-ROM or the like). Can also be provided.
