Description

  The present invention relates to a network device control system that controls network devices connected to a network.

  With the spread of computers and communication networks, the importance of computer network management is increasing. A network management system that manages a computer network is a system that monitors the operating status of devices connected to the network, network traffic, and the like for the purpose of preventing network failures and improving the performance of the entire network.

  When generating a configuration file for a network device, there is no setting mistake or inconsistency, and it is easy to automatically create a network equivalent to that network diagram from a network diagram described interactively regardless of the various devices. There is provided a network design support system capable of generating network device setting information for realizing the above (see, for example, Patent Document 1).

A management server in the network management system implements a program called an SNMP manager, and monitors the status of network devices such as routers and hubs connected to the network, traffic status, and the like. In addition, the managed network device has a program called an SNMP agent, and has information called an MIB (Management Information Base) (management information base). The SNMP agent acquires information stored in the MIB and notifies the SNMP manager. The MIB is information including setting information such as model information (sysObjectID) and administrator information (sysContact) that can identify the vendor and model of the network device, information indicating traffic volume and resource consumption, and the like. Each piece of information is called an object.

In the example shown in FIG. 1, only the network devices 10A and 10B are described as the control target devices, but may be one or two or more.

  The network device control server 100 includes a GUI (Graphical User Interface) 1, a network device control unit 2, a network device information storage unit 3, a correspondence definition file 4, and an execution command format 5.

The GUI 1 has a function of executing input / output control such as controlling information input from an input unit (not shown) such as a keyboard or a mouse, or performing graphic display on a display unit (not shown). . The GUI 1 outputs information such as registration information and control parameters input from the input unit to the network device control unit 2.

  The network device control unit 2 has a function of registering a network device as a control target device and executing a process of acquiring MIB information. The network device control unit 2 uses the registration information output from the GUI 1 to acquire MIB information from the control target device by SNMP, and stores the registration information and the acquired MIB information in the network device information storage unit 3. The network device control unit 2 acquires sysObjectID as MIB information.

  The network device information storage unit 3 is a storage device that stores registration information and MIB information. FIG. 2 is an explanatory diagram illustrating an example of registration information and MIB information stored in the network device information storage unit 3. As illustrated in FIG. 2, the registration information is information for each control target device, and includes information including the host name, SNMP community name, and login password of the control target device. The registration information is information necessary for the network device control server 100 to access the control target device, and is information used when acquiring MIB information from the control target device by SNMP. MIB information is information including sysObjectID, and is stored in association with registration information for each control target device. FIG. 2 illustrates a case where only sysObjectID is stored as MIB information, but other objects may be acquired and stored together. The host name may be an IP address.

  Further, the network device control unit 2 has a function of executing processing for acquiring information necessary for executing processing on the command line with respect to the control target device. The network device control unit 2 searches the network device information storage unit 3 based on the host name of the control parameter output from the GUI 1, and acquires the control target device registration information and MIB information (sysObjectID).

  FIG. 3 is an explanatory diagram illustrating an example of control parameters. The control parameter is an argument necessary for executing processing on the control target device on the command line, and is information including the host name of the control target device. FIG. 3 is an example showing control parameters necessary for setting a VLAN (Virtual Local Area Network) for a switching hub that is a device to be controlled. The control parameter is a host name (HOST_NAME) of the switching hub. , Information including a VLAN ID (VLAN_ID) for identifying the VLAN, a connection port number (PORT_NO) assigned to the VLAN, and an IP address (IP).

  The network device control unit 2 searches the correspondence definition file 4 based on the acquired sysObjectID, and acquires the file name of the execution command format 5.

  The correspondence definition file 4 is a data file in which the correspondence relationship between the sysObjectID and the file name of the execution command format 5 is defined. FIG. 4 is an explanatory diagram showing an example of correspondence definition information stored in the correspondence definition file 4. The correspondence definition information is information including the sysObjectID and the execution command format 5 file name.

FIG. 5 shows an example of a command format when setting a VLAN for a switching hub that is a control target device, and indicates that the part in parentheses is a keyword. The keyword in the command format illustrated in FIG. 5 corresponds to the item name of the control parameter illustrated in FIG.

  The network device control unit 2 replaces the acquired command format keyword with the control parameter output from the GUI 1 to generate a command image.

  The network device control unit 2 has a function of executing a process on a control target device on the command line. The network device control unit 2 uses the acquired registration information to log in to the control target device with telnet or the like, executes the generated command image, and stores the execution result in the network device information storage unit 3.

  When the network device control server 100 is realized by a server device, the network device control unit 2 is realized by the CPU mounted on the network device control server 100 executing a program for realizing the function. The

  In the first embodiment, the model identification information acquisition unit, the command format information acquisition unit, the command information generation unit, and the execution unit are realized by the network device control unit 2. The device information storage means is realized by the network device information storage unit 3. The correspondence definition storage means is realized by the correspondence definition file 4 and the execution command format 5.

  Next, the operation of the first embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating the operation of the network device control system according to the first embodiment. Hereinafter, a case where the network device control server 100 controls the network device 10A will be described as an example.

  When the registration information is input from the input unit by the network administrator or the like when the network device 10A is introduced, the GUI 1 outputs the input registration information to the network device control unit 2 (step S101). Hereinafter, a case where the registration information illustrated in FIG. 2 is input will be described as an example. Referring to FIG. 2, the input registration information has a host name “host10A”, an SNMP community name “snmpB”, and a login password “pwC”.

  The network device control unit 2 uses the registration information output from the GUI 1 to acquire MIB information from the network device 10A by SNMP (step S102), and stores the registration information and the acquired MIB information in the network device information storage unit 3. Store (step S103). For example, as illustrated in FIG. 2, the sysObjectID “1.3.6.1.1.4.242” of the MIB information is stored in association with the registration information.

  A plurality of pieces of information may be input at a time as registration information. In addition, registration information and MIB information of a plurality of network devices may be automatically stored in the network device information storage unit 3 by specifying a range of IP addresses instead of host names. By performing the processing from step S101 to step S103, the network device 10A can be controlled by the network device control server 100.

  When controlling the network device 10A, when a control parameter is input from the input unit by a network administrator or the like, the GUI 1 outputs the input control parameter to the network device control unit 2 (step S104). Hereinafter, the case where the control parameter illustrated in FIG. 3 is input will be described as an example. Referring to FIG. 3, the input control parameters are host name “host10A”, VLAN ID “10”, connection port number “1”, and IP address “XXX.XXX.XXX.XXX”.

  The network device control unit 2 searches the network device information storage unit 3 based on the host name of the control parameter output from the GUI 1, and obtains registration information and sysObjectID of the network device 10A (step S105). As illustrated in FIG. 3, the host name of the control parameter is “host10A”. The network device control unit 2 searches the network device information storage unit 3 using the host name “host10A” as a key, and acquires the registration information and the sysObjectID shown in FIG.

  The network device control unit 2 searches the correspondence definition file 4 based on the acquired sysObjectID, and acquires the file name of the execution command format 5 (step S106). Referring to FIG. 4, the network device control unit 2 searches the correspondence definition file 4 shown in FIG. 4 using the acquired sysObject ID “1.3.6.1.1.4.242” as a key. The file name “file10A” of the execution command format 5 is acquired.

  The network device control unit 2 acquires a command format based on the acquired file name of the execution command format 5. If the file name of the command format shown in FIG. 5 is “file10A”, the network device controller 2 acquires the command format shown in FIG. 5 using the file name “file10A” of the execution command format 5 as a key.

  The network device control unit 2 replaces the acquired command format keyword with the control parameter output from the GUI 1 to generate a command image (step S107). In the example illustrated in FIG. 5, [VLAN_ID] and [PORT_NO] correspond to keywords. The network device control unit 2 replaces the [VLAN_ID] and [PORT_NO] portions of the command format with the VLAN ID “10” and PORT_NO “1” in the control parameter to generate a command image. FIG. 7 is an explanatory diagram illustrating an example of a command image generated by the network device control unit 2.

  The network device control unit 2 logs in to the network device 10A with telnet using the acquired registration information (step S108). For example, the network device control unit 2 logs in to the network device 10A with telnet using the host name “host 10A” and the login password “pwC” shown in FIG.

  In step S108, when the user logs in to the network device 10A via telnet, the network device control unit 2 causes the network device 10A to execute the generated command image (step S109). In the example shown above, the network device control unit 2 causes the network device 10A to execute the generated command image.

  The network device control unit 2 stores the execution result of the command image in the network device information storage unit 3 (step S110). The execution result may be stored in association with the registration information.

  As described above, according to the first embodiment described above, since the command image is executed by logging in with telnet, there is an effect that control not defined as the standard MIB by SNMP becomes possible. .

  When the network administrator inputs control parameters, the network device control server 100 automatically generates and executes a command image corresponding to the network device. Therefore, there is an effect that the network administrator can easily control the network device without being aware of the difference in the command format depending on the model.

  Furthermore, even when a new model of network device is added, new correspondence definition information is defined in the correspondence definition file, and a new file may be added as the execution command format 5 to facilitate the correspondence. There is an effect.

FIG. 10 is a flowchart illustrating the operation of the network device control system according to the second embodiment. Hereinafter, a case where the network device control server 200 controls the network device 10A will be described as an example.

  When the registration information is input from the input unit by the network administrator or the like when the network device 10A is introduced, the GUI 1 outputs the input registration information to the network device control unit 12 (step S201). Hereinafter, a case where the registration information illustrated in FIG. 2 is input will be described as an example. Referring to FIG. 2, the input registration information has a host name “host10A”, an SNMP community name “snmpB”, and a login password “pwC”.

Store (step S203). As illustrated in FIG. 2, the sysObjectID “1.3.6.1.4.1.4.1242” of the MIB information is stored in association with the registration information.

  A plurality of pieces of information may be input at a time as registration information. In addition, registration information and MIB information of a plurality of network devices may be automatically stored in the network device information storage unit 3 by specifying a range of IP addresses instead of host names. By performing the processing from step S201 to step S203, the network device 10A can be controlled by the network device control server 200.

  When controlling the network device 10A, when a control parameter is input from the input unit by a network administrator or the like, the GUI 1 outputs the input control parameter to the network device control unit 12 (step S204). Hereinafter, the case where the control parameter illustrated in FIG. 3 is input will be described as an example. Referring to FIG. 3, the input control parameters are host name “host10A”, VLAN ID “10”, connection port number “1”, and IP address “XXX.XXX.XXX.XXX”.

  The network device control unit 12 searches the network device information storage unit 3 based on the host name of the control parameter output from the GUI 1, and obtains registration information and sysObjectID of the network device 10A (step S205). As illustrated in FIG. 3, the host name of the control parameter is “host10A”. The network device control unit 12 searches the network device information storage unit 3 using the host name “host 10A” as a key, and acquires the registration information and the sysObjectID shown in FIG.

  The network device control unit 12 searches the correspondence definition file 4 based on the acquired sysObjectID, and acquires the file name of the execution command script 15 (step S206). Referring to FIG. 4 as an example, the network device control unit 12 searches the correspondence definition file 4 shown in FIG. 4 using the acquired sysObject ID “1.3.6.1.1.4.242” as a key. The file name “file10A” of the execution command script 15 is acquired.

  The network device control unit 12 acquires the format of the command script based on the acquired file name of the execution command script 15. If the file name of the command format shown in FIG. 9 is “file10A”, the network device control unit 12 acquires the format of the command script shown in FIG. 9 using the file name “file10A” of the execution command script 15 as a key. .

  The network device control unit 12 replaces the keyword of the acquired command script format with the control parameter output from the GUI 1, and generates a command script (step S207). In the example illustrated in FIG. 9, [VLAN_ID] and [PORT_NO] correspond to keywords. The network device controller 12 generates a command script by replacing [VLAN_ID] and [PORT_NO] in the command script format with VLAN_ID “10” and PORT_NO “1” in the control parameters, respectively. FIG. 11 is an explanatory diagram illustrating an example of a command script generated by the network device control unit 2.

In the example shown above, the network device control unit 12 causes the network device 10A to execute the generated command script line by line.

  The network device control unit 12 stores the execution result of the command script in the network device information storage unit 3 (step S210).

  As described above, according to the second embodiment, in addition to the effects of the first embodiment, the execution command script 15 executes a process, so that a specific response is obtained after the command is executed. You can wait until there is, or change the command to be executed next depending on the response. For example, if an error occurs in the middle of a process consisting of a plurality of commands, the rollback process can be performed by writing in the execution command script 15 to execute a command for canceling the process of a command that has already ended.

Embodiment 3 FIG.
Next, a third embodiment of the present invention will be described with reference to the drawings. In the third embodiment, the executed command is captured and the execution command script itself is automatically generated. It is assumed that the network device information storage unit 3 stores registration information and MIB information in advance.

The network device control server 300 is communicably connected to control target devices such as the network device 10A and the network device 10B via a communication network.

  The network device control server 300 includes a GUI 1, a network device control unit 22, a network device information storage unit 3, a correspondence definition file 4, and an execution command script 15.

  The GUI 1 outputs information such as selection information and commands input from the input unit to the network device control unit 22. The selection information is information including the host name of the device to be controlled, and is information selected from the host name stored in the network device information storage unit 3.

  The network device control unit 22 searches the registration information and MIB information in the network device information storage unit 3 based on the host name of the selection information output from the GUI 1, and acquires the registration information and the sysObjectID of the control target device.

  Further, the network device control unit 22 has a terminal emulator function for inputting and executing a command on the command line, and has a function of executing a command by logging in to the control target device with telnet or the like using the acquired registration information. . The network device control unit 22 outputs display data for the terminal emulator screen to the GUI 1, and the GUI 1 displays the data on the display unit.

  A command input from an input unit such as a keyboard is output to the network device control unit 22 via the GUI 1. The network device control unit 22 causes the network device 10A to execute the command.

  The network device control unit 22 captures the command input on the terminal emulator screen and stores it as a new file of the execution command script 15. At that time, the network device control unit 22 generates a file name of the new file of the execution command script 15.

  When the network device control unit 22 receives a response character string from the network device 10A after executing the command, the network device control unit 22 generates a script line that waits for the received response character string and writes it to a new file of the execution command script 15.

  Further, the network device control unit 22 generates correspondence definition information by associating the acquired sysObjectID with the generated new file name of the execution command script 15 and stores the correspondence definition information in the correspondence definition file 4.

  In the third embodiment, the model identification information acquisition unit, the command format information acquisition unit, the command information generation unit, the execution unit, and the command format information generation unit are realized by the network device control unit 22.

  First, when selection information is input from the input unit by a network administrator or the like, the GUI 1 outputs the input selection information to the network device control unit 2 (step S301). Hereinafter, a case where the host name “host10A” is input as selection information will be described as an example.

  The network device control unit 22 searches the network device information storage unit 3 based on the host name of the selection information output from the GUI 1, and acquires registration information and sysObjectID of the control target device (step S302). For example, the network device control unit 2 searches the network device information storage unit 3 using the host name “host10A” as a key, and acquires the registration information and the sysObjectID shown in FIG.

  The network device control unit 2 logs in to the network device 10A with telnet using the acquired registration information (step S303). For example, the network device control unit 2 logs in to the network device 10A with telnet using the host name “host 10A” and the login password “pwC” shown in FIG.

  When the terminal emulator screen is displayed on the display unit by the processing of the network device control unit 2 and the GUI 1, the network device control unit 2 starts capturing (step S304). When a command is input from the input unit by a network administrator or the like, the network device control unit 22 causes the network device 10A to execute the command (step S305).

  The network device control unit 22 captures the command input on the terminal emulator screen and generates a script line (step S306). The network device control unit 22 stores the generated script line in a new file of the execution command script 15. The network device control unit 22 generates and saves a file name in the new file of the execution command script 15.

  The network device control unit 22 receives a response character string from the network device 10A after executing the command (step S307). The network device control unit 22 generates a script line that waits for the received response character string, and writes it to a new file of the execution command script 15 (step S308).

  The network device control unit 22 determines whether or not the command input is completed (step S309), and if it is determined that the command input is completed, the network device control unit 22 proceeds to step S310. If it is determined that the process has not been completed, the process proceeds to step S305, and the processes from step S305 to step S309 are repeated.

  In step S310, the network device control unit 22 generates correspondence definition information by associating the acquired sysObjectID with the generated new file name of the execution command script 15, and stores the correspondence definition information in the correspondence definition file 4 (step S310).

  If the automatically generated execution command script 15 has control parameters such as VLAN ID and connection port number, the user rewrites the corresponding part into a keyword representing the control parameter (step S311).

  In the third embodiment, the execution command script is generated as a new file. However, the execution command format may be used. In this case, the network device control unit 22 does not need to generate a script line that receives the response character string and waits for the received response character string.

  As described above, according to the third embodiment, once the command is executed, new correspondence definition information is automatically defined, and a new file is added as the execution command script 15. Therefore, there is an effect that the subsequent correspondence becomes easier.

  The present invention can be applied to control network devices connected to a network, and in particular, can be effectively applied to easily control network devices having different control methods for each model.
