Abstract

<P>PROBLEM TO BE SOLVED: To successfully set information to a plurality of switching hubs without the need for a manager to be conscious of an interconnection state of the plurality of switching hubs. <P>SOLUTION: A network device configuration management apparatus 101 first performs redundant protocol setting in setting to switching hubs and performs the remaining setting in a following order. Namely, an identifier (called importance degree) indicating importance of each setting target switching hub is allocated on the basis of the number of physical connection stages from a switching hub constructing a redundant network to the setting target switching hub. Regarding the setting target switching hub, setting is started from a switching hub with the highest importance degree on a condition that there is no switching hub on a route to the other setting target switching hub. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a network device configuration management system and management method, and more particularly, to a network device configuration management system and management method for collecting information from a switching hub that is a network device constituting a network and performing various settings for the switching hub. .

  As a prior art related to a technique that enables management of network devices at a small maintenance management cost by collectively managing setting information of a plurality of network devices such as switching hubs, for example, Patent Document 1 The described technique is known. In this prior art, when the setting information of a plurality of switching hubs constituting a network is changed, depending on the setting order, the communication route on the network is changed due to the change of the setting of the switching hub. The setting of information to the server may fail.

In addition, as a method for setting information for a plurality of switching hubs at the same time, for example, a technique called VLAN Trunking Protocol (VTP) supported by the switching hub of Cisco is known in order to collectively manage VLANs. . In addition, as a method for performing setting to the target switching hub without considering the change of the network path, a method for constructing a management-dedicated network using the management port of the switching hub is known.
JP 2002-190809 A

  However, the technique using a dedicated protocol such as VTP has a problem that all switching hubs on the network need to support the protocol. In addition, the method of constructing a management-dedicated network has the same problem that all the switching hubs on the network must have a management-dedicated port, and the management-dedicated network must be maintained and operated. Therefore, there is a problem that the burden on the operation manager is large.

  If a dedicated protocol such as VTP as described above or a management dedicated network cannot be used, some switching hubs can be configured by simultaneously setting information in a plurality of switching hubs without considering the connection relationship between the switching hubs. In some cases, it may not be possible to complete the intended setting, such as the setting not being delivered. For this reason, in order to avoid this, it is necessary for the administrator to check the connection state between the switching hubs and to consider the order in which no problem occurs. However, if a redundancy protocol such as STP is set on the switching hub, the logical connection state of the switching hub changes depending on the network failure state, so the validity of the setting order studied in advance is guaranteed. It will not be done.

  In addition, when setting information in a plurality of switching hubs, it is desired to finish setting information preferentially from switching hubs with high importance in consideration of the importance of each switching hub.

  In view of the above-described points, the object of the present invention is to make it possible for an administrator to successfully set information on a plurality of switching hubs without having to be aware of the connection state between the plurality of switching hubs. It is an object of the present invention to provide a network device configuration management system and management method capable of preferentially setting information in a high switching hub and quickly ending the startup of an important network.

  According to the present invention, the object is to provide a network device configuration management system for performing various settings for a switching hub, which is a network device constituting a network, in a network to which a plurality of switching hubs are connected. The network configuration device management device is configured by connecting a management device, and the network configuration device management device acquires configuration information of a switching hub that is a management target device, and switch setting information acquisition unit that acquires the setting information of the switching hub And a setting path creating means for creating a logical connection path from the network device configuration management device to the switching hub from the acquired configuration information and setting information, and a plurality of switching settings when changing settings for a plurality of switching hubs. Switchon connected to the stage By comprising a setting order determining means for determining the order of setting so as to give priority to the setting for the switching hub far from the network component management device of the hub, and a switch setting means for setting the switching hub. Achieved.

  According to the present invention, when information is set in a plurality of switching hubs, the setting of other switching hubs does not fail due to a change in the network configuration due to the setting of a certain switching hub as a network device, and is important. It is possible to automatically determine a setting order in which information can be preferentially set in a switching hub having a high degree, and the management burden on the network can be reduced.

  FIG. 13 is a flowchart for explaining the processing operation in the redundancy group creation processing unit 112, which will be described next.

(1) First, the redundancy group creation processing unit 112 acquires the setting information regarding the redundancy flag and each redundancy protocol of each port from the port setting information table 205 (step 1301).

(2) Next, the processing from step 1303 to step 1307 is performed for all ports for which it has been confirmed that the redundancy protocol is set by the redundancy flag acquired in step 1301. It is set to repeat (step 1302).

(3) Next, it is set to repeat the processing in steps 1304 to 1306 for the redundancy topology ID of the redundancy protocol set in the port (step 1303).

(4) After that, it is determined whether or not the redundancy topology ID is already set and registered in the redundancy group table 203. If not, the redundancy topology ID and the redundancy topology name are made redundant. It is set and registered in the group table 203 (steps 1304 and 1305).

(5) If the redundancy topology ID has already been set and registered in the redundancy group table 203 in the determination in step 1304, or after the registration processing in step 1305, the switch IP address and port identifier Are added to the corresponding redundancy topology ID in the redundancy group table 203 (step 1306).

(6) When the repetition processing set in steps 1302 and 1303 is completed, the redundancy group creation processing here ends (steps 1307 and 1308).

  FIG. 14 is a flowchart for explaining the processing operation in the port setting information update processing unit 114, which will be described next.

(1) The port setting information update processing unit 114 first reads the switch configuration information table 201 and acquires the state 405 of each port (step 1401).

(2) Next, it is set that the processing of steps from step 1403 to step 1409 is repeated for the port whose port status acquired in the processing of step 1401 has been updated (step 1402).

(3) Then, based on the value of the redundancy flag 803 in the port setting information table 205, it is determined whether or not the setting relating to the redundancy protocol is performed on the port in which the update of the port state is detected (step 1403). .

(4) If it is determined in step 1403 that a setting related to the redundancy protocol has been set for the port in which the update of the port state is detected, the processing of steps from step 1405 to step 1408 is performed for the redundancy to which the port belongs. It is set to repeat for each topology ID (step 1404).

(5) After that, the return time 301 from the disconnection corresponding to the set redundancy protocol is read from the redundancy return time table 210, and the process waits for the read return time (steps 1405 and 1406).

(6) After waiting for the process for the return time, the port setting information reacquisition processing unit 115 is executed for the target redundant topology ID. The operation of the port setting information reacquisition processing unit 115 will be described later with reference to the flow shown in FIG. 15 (step 1407).

(7) The port setting information reacquisition processing unit 115 in the process of step 1407 determines whether or not the switch information can be acquired. If the switch information cannot be acquired, the process proceeds from step 1406. The processing is repeated by returning to the above processing (step 1408).

(8) If the switch information can be acquired in the determination in step 1408, the port setting information update processing here ends when the repetition processing set in steps 1404 and 1402 ends (step 1409). 1410).

  FIG. 15 is a flowchart for explaining the processing operation in the port setting information reacquisition processing unit 115 in step 1407 shown in FIG. 14, and this will be explained next.

(1) When the processing is started, the port setting information reacquisition processing unit 115 first reads the redundancy group table 203 and extracts ports belonging to the target redundancy topology ID (step 1501).

(2) Next, it is set to repeat the processing in steps 1503 and 1504 for the port extracted in the processing in step 1501 (step 1502).

(3) Thereafter, the setting information of the target port is acquired from the switching hub by using a protocol or API such as telnet or http determined by the switching hub, and the acquired port setting information is reflected in the port setting information table 205. (Steps 1503 and 1504).

(4) When the repetition processing set in step 1502 is completed, the port setting information reacquisition processing unit is terminated (step 1505).

  FIG. 16 is a flowchart for explaining the processing operation in the switch setting processing unit 116, which will be described next.

(1) The switch setting processing unit 116 first reads the user setting information table 207 created by the administrator using the input device 110 and the output device 108, and sets the redundancy protocol in the read user setting information table 207. It is determined whether or not there is a switching hub that performs (steps 1601 and 1602).

(2) If it is determined in step 1602 that there is a switching hub that performs settings related to the redundancy protocol, the redundancy protocol setting processing unit 117 is executed. The reason for setting only the redundancy protocol in advance is that the configuration for the switching hub is changed during the setting for the switching hub, so that the redundancy topology that is a network made redundant by the redundancy protocol can be changed again. This is for the purpose of predicting and controlling the switching hubs that make up the redundant topology, which may be unable to communicate due to the calculation. The operation of the redundancy protocol setting processing unit 117 will be described later with reference to the flow shown in FIG. 17 (step 1603).

(3) After the process of step 1603 or when there is no switching hub that performs the setting related to the redundancy protocol in the determination of step 1602, the setting route creation processing unit 118 is executed. The setting path creation processing unit 118 is a process for creating the path information table 206 based on the contents of the physical connection information table 202, the switch configuration information table 201, the setting information table 204, and the port setting information table 205. The operation of the setting route creation processing unit 118 will be described later with reference to the flow shown in FIG. 20 (step 1604).

(4) Next, importance level determination processing 119 is executed, and an importance level table 208 is created based on the contents of the switch configuration information table 201, physical connection table 202, and user setting information table 207. The operation of the importance level determination process 119 will be described later with reference to the flow shown in FIG. 18 (step 1605).

(5) Next, the setting order determination processing unit 120 is executed, and a setting order table 209 is created based on the contents of the route information table 206, the user setting information table 207, and the importance level table 208. The operation of the setting order determination processing unit 120 will be described later with reference to the flow shown in FIG. 19 (step 1606).

(6) Finally, settings other than the redundancy protocol are executed for each switching hub in the setting order shown in the setting order table 209, and the process in the switch setting processing unit 116 is terminated (step 1607). ).

  FIG. 17 is a flowchart for explaining the processing operation of the redundancy protocol setting processing unit 117 in step 1603 of the flow shown in FIG. 16, and this will be described next.

(1) When the processing is started, the redundancy protocol setting processing unit 117 first reads the user setting information table 207 and extracts the redundancy topology ID to be set from the setting contents of each redundancy protocol (step 1701). ).

(2) Next, it is set to repeat the processing in steps 1708 and 1703 to 1710 for the redundant topology ID extracted in step 1701 (step 1702).

(3) Next, it is set that the processing from step 1703 to step 1706 is repeated for the switching hub that is a member of the corresponding redundancy topology ID in the redundancy group table 203 (step 1708).

(4) Next, the setting belonging to the target redundancy topology ID is performed for the switching hub to be set. This setting is performed using a protocol such as telnet or http determined by the switching hub or an API (step 1703).

(5) The redundancy return time table 210 is read, and the return time 202 from the change of the redundancy configuration of the redundancy protocol set in the processing of step 1703 is acquired (step 1704).

(6) The processing waits for the return time read in the processing in step 1704, and thereafter, the port setting information reacquisition processing unit 115 is executed for the redundant topology ID set in the processing in step 1703 (step 1705, 1706).

(7) The processing of steps 1703 to 1706 is repeated for the switching hub that is a member of the corresponding redundancy topology ID in the redundancy group table 203, and then the port setting information reacquisition processing of step 1706 is performed. If the redundancy topology ID set for the target port is changed due to the change of the redundancy protocol setting in the contents of the port setting information table 205 changed by the processing of the unit 115, the contents are made redundant. To be reflected in the group group table 203. If the redundancy topology ID set in step 1703 is not registered in the redundancy group table 203, new registration is performed (steps 1709 and 1710).

(8) Steps 1708 and steps 1703 to 1710 are repeated for the redundancy topology ID extracted in step 1701, and then the redundancy protocol setting processing unit 117 is terminated (step 1706). ).

  FIG. 20 is a flowchart for explaining the processing operation of the setting route creation processing unit 118 at step 1604 of the flow shown in FIG. 16, and this will be described next. The flow shown here is composed of two flows: an overall processing flow shown in FIG. 20A and a determination routine flow shown in FIG.

(1) First, the set route creation processing unit 118 starts processing of the flow shown in FIG. 20A to create pseudo packet information. Here, the pseudo packet information is a collection of information that virtually reproduces the header information of a communication packet transmitted when communication is performed based on the network device configuration management device (step 2001).

(2) Next, the determination routine according to the flow shown in FIG. 20B is executed for the port of the switching hub to which the network device configuration management apparatus 101 is connected. The creation processing unit 118 ends. It is assumed that the port of the switching hub to which the network device configuration management apparatus 101 is connected is designated in advance by the system administrator (step 2002).

(3) When the determination routine is started, the switching hub to which the port executing the determination routine belongs is determined from the switch configuration information table 201, and it is determined whether the switching hub has been registered in the path information table 206 ( Step 2011, 2003).

(4) If the relevant switching hub has not been registered in the route information table 206 in the determination in step 2003, the route to the port that executes the determination routine is set as the route to the switching hub to which the port that the determination routine executes belongs. Registered in the route information table 206. The route to the port that executes the determination routine is indicated by the order of the ports that have been traced since the set route creation processing unit 118 was executed (step 2004).

(5) After the process of step 2004 or when the relevant switching hub has already been registered in the route information table 206 in the determination of step 2003, the process of steps from step 2006 to step 2009 is executed. The other ports of the switching hub to which the ports to be assigned belong are acquired from the switch configuration information table 201 and set to repeat for those ports (step 2005).

(6) Thereafter, it is determined whether or not communication is possible between the port on which the determination routine is executed and the port to be looped. This determination is performed using the information on the pseudo packet created in step 2001, the information in the setting information table 204, and the port setting information table 205. That is, the determination is performed by determining how the pseudo packet is controlled from the setting information of the switching hub recorded in the setting information table 204 and the port setting information table 205. In addition, depending on the setting contents, the switching hub may perform an operation of rewriting communication packet information. In this case, the contents of the pseudo packet are rewritten according to the setting information (step 2006).

(7) If communication is possible in the determination in step 2006, it is determined whether or not the port to be looped is registered in the physical connection table 202 (step 2007).

(8) If it is determined in step 2007 that the loop target port is registered in the physical connection table 202, the loop target port and the loop target port registered in the physical connection table 202 It is determined whether or not communication with the connected port is possible. The determination method is the same as the determination method in step 2006 (step 2008).

(9) If communication is possible in the determination in step 2008, the determination routine from step 2011 is executed for the port to which the port to be looped is connected. Also, the pseudo packet information is copied, and if the pseudo packet information is updated in the execution destination determination routine, the copied pseudo packet is updated (step 2009).

(10) After the process in step 2009, if communication cannot be performed in the determination in step 2006, if the port to be looped is not registered in the physical connection table 202 in the determination in step 2007, or If communication cannot be performed in the determination of step 2008, the processing in steps from step 2006 to step 2009 is repeated for all acquired ports, and then the processing of the determination routine is terminated. Then, the setting route creation processing unit 118 is terminated (step 2010).

  FIG. 18 is a flowchart for explaining the processing operation of the importance degree determination processing unit 119 in step 1605 of the flow shown in FIG. 16, and this will be described next.

(1) When the processing is started, the importance level determination processing unit 119 reads the setting information table 205 and the physical connection table 202, and also reads the user setting information table 207 to extract a switching hub to be set (step 1801). ˜1803).

(2) Next, it is set to repeat the processing in step 1805 and step 1806 for the switching hub extracted in the processing in step 1803 (step 1804).

(3) The physical connection table 202 and the port setting information table 205 indicate the number of physical connection stages from the target switching hub to the switching hub having the smallest physical connection stage number and the port for which the redundancy protocol is set. Using the information, the following is obtained, and the obtained number of connection stages is set as the importance (step 1805).

  First, a switching hub having a port for which a redundancy protocol is set is extracted from the port setting information table 205. The number of connection stages of these extracted switching hubs is 0, and the importance is 0.

  Next, the switching hub that is the connection destination of the port of the switching hub that has been made redundant is extracted from the physical connection table 202. The number of connection stages of these switching hubs is 1, and the importance level is 1.

  Further, the switching hub to which the extracted switching hub port is connected is extracted from the physical connection table 202. Of the extracted switching hubs, switching hubs for which the number of connection stages has not yet been determined are further extracted. Since these extracted switching hubs are connected two stages ahead of the first extracted switching hub, the number of connection stages is 2, and the importance level is 2.

  As described above, the connection destination of the switching hub is traced from the physical connection table 202, the number of connection stages is increased by one, and the importance is assigned. In addition, importance is so high that the value (number of connection stages) is small.

  The above processing is performed for each switching hub for which the redundancy protocol is set, and the number of connection stages to other switching hubs is obtained. Thereby, the number of connection stages corresponding to the number of switching hubs for which the redundancy protocol is set is obtained for each switching hub, and the smallest value among the connection stages is set as the number of connection stages of the switching hub.

(4) After the above-described processing is completed, the number of physical connection stages obtained in step 1804 is stored in the importance level table 208 as the importance level of the target switching hub (step 1806).

(5) When the processing of step 1805 and step 1806 is repeated for the switching hub extracted in the processing of step 1803, the importance level determination processing unit 119 is ended (step 1807).

  FIG. 19 is a flowchart for explaining the processing operation of the setting order determination processing unit 120 at step 1606 of the flow shown in FIG. 16. Next, this will be described.

(1) When the processing is started, the setting order determination processing unit 120 reads the route information table 206 and the importance level table 208 and also reads the user setting information table 207 (steps 1901 to 1903).

(2) Next, out of the switching hubs in the user setting information table 207, a switching hub that performs a setting other than the setting related to the redundancy protocol is extracted as a setting target switch. This process is performed because the setting relating to the redundancy protocol is completed in the process of step 1603 described with reference to the flow shown in FIG. 16 (step 1904).

(3) Next, among the setting target switches extracted in the process of step 1904, it is not on the path of other setting target switches not stored in the setting order table 209, and the path information table 206 read in step 1901. What can be confirmed from the contents of is extracted as a setting candidate switch. This process is performed in order to prevent communication with other setting target switching hubs from being interrupted due to a setting change to a certain setting target switching hub (step 1905).

(4) Of the setting candidate switches extracted in the processing of step 1905, the switch having the smallest importance value on the importance table 208 is stored in the setting order table 209. As a result, among the setting candidate switches, the setting order is determined so that the switching hub with high importance that configures the redundant network is preferentially set (step 1906).

(5) It is determined whether or not all the setting orders of the setting target switches extracted in step 1904 are stored in the setting order table 209. If they are stored, the setting order determination processing unit 120 is terminated and is not stored. If so, the process returns to step 1905 to repeat the process (step 1907).

  Each process in the above-described embodiment of the present invention is configured by a program and can be executed by a CPU included in the present invention. These programs are stored in a recording medium such as an FD, CDROM, or DVD. It can be provided and can be provided by digital information via a network.

  The above-described embodiment of the present invention collects switching hub configuration information and setting information from each switching hub, and updates this information as needed when a failure occurs in the switching hub. When setting is performed for a plurality of switching hubs, first, the setting contents are classified into a protocol for redundancy and settings for configuring other networks, for example, settings for VLAN and ACL. After classifying the settings, first, settings related to the protocol for redundancy are made for each switching hub. Here, when the setting of the protocol for redundancy is changed, the network path may be changed. Therefore, the switching hub information is reacquired for each redundancy unit of the protocol for redundancy. After completing the redundancy setting, a logical path from the network device management system to the setting target switching hub is constructed based on the reacquired information. Also, an identifier indicating the importance of each setting target switching hub, here called importance, this importance is given to each setting target switching hub. The degree of importance is determined based on the number of physical connection stages from the switching hub that configures the redundant network to the setting target switching hub. This is because the switching hub that constructs the redundant network and the surrounding switching hubs are considered to be important in constructing the network. Finally, settings other than the redundancy protocol for the switching hub are performed, and the following method is used. With respect to the switching hub to be set, the setting is performed from the switching hub having the highest importance when the switching hub is not on the path to the other switching hub. As a result, a change in the network configuration due to settings for one switching hub can be prevented from affecting other switching hubs, and switching hubs that are predicted to be highly important are automatically determined and given priority. Can be set.
