The management computer manages a plurality of nodes that constitute a network accommodating VLANs. The plurality of nodes include a first node and a second node which make a redundancy pair and which divides the network into an active path and a standby path. The management computer stores port management information showing connection relations for respective nodes and identifiers of VLANs allocated to ports of the nodes, and creates the redundancy pair by updating the port management information of the first node such that a VLAN allocated to one of ports of a connected node that is connected to the first node is allocated to one of ports of the first node that is connected to the connected node.

Description

The redundancy establishing method of supervisory computer
Technical field
The present invention relates to a kind of supervisory computer of supervising the network, especially relate to the supervisory computer that automatic setting constitutes the switch of network.
Background technology
In recent years, advance the networking of each business (business that comprises mission critical (mission critital)) in the enterprise, require to improve the availability of network.
Now, when in the network equipments such as switch and router, breaking down, network manager exchanges the network equipment that breaks down through handwork.At this moment, during before finishing in the network equipment exchange of breaking down, can not communicate in this network, so the availability of network reduces greatly.
Here, the agreement of known so-called STP (Spanning Tree Prorocol).STP is when in the network that is made up of switch, breaking down, and recovers the control protocol of the inter-exchange that network uses automatically.When in network, breaking down, each switch uses STP self-discipline ground to carry out the processing that recovers this network failure.Therefore, owing to, automatically perform the processing of recovered failure when in network, breaking down,, can improve the availability of network so compare through the situation that handwork recovers network failure with network manager according to STP.
And, become known for further improving so-called VRRP (VirtualRouter Redundancy Protocol) and the agreement of GSRP (Gigabit Switch RedundacyProtocol) of the availability of network.The scope of these agreement recovered failure is limited to adjacent (interconnected) network equipment.These agreements are control protocols of the redundancy switch that is made up of current use system switch and standby system switch.Claim that below VRGP and GSRP are the redundant system control protocol.
Because according to the redundant system control protocol, the scope of recovered failure is limited to the adjacent network equipment, so compare with utilizing the STP recovered failure, can recover network at short notice.
In order to be suitable for the redundant system control protocol, network manager connects other switches in the network on two switches that constitute the redundancyization switch.And network manager is set via the current use system path of a switch that constitutes redundancyization switch with via the standby system path of another switch of formation redundancyization switch.In addition, with among two switches that constitute the redundancyization switch, be called the current use system switch via the switch in current use system path, will be called the standby system switch via the switch in standby system path.
Network manager moves the redundant system control protocol between current use system switch and standby system switch.The current use system switch uses the redundant system control protocol, keeps watch on the operating condition of standby system switch, and the standby system switch uses the redundant system control protocol, keeps watch on the operating condition of current use system switch.
In addition, before the port beyond the port among the port that the standby system switch possesses, that connect the current use system switch breaks down in the current use system switch during, set the holding state that stops to communicate by letter for.In addition, the port of this holding state is the port that becomes the object of the automatic recovery processing of using the execution of redundant system control protocol.
And; Network manager when selecting GSRP as the redundant system control protocol, connect in the port that the current use system switch is possessed the standby system switch port, and the port that possesses of standby system switch in connect the current use system switch ports-settings become based on port GSRP, that in inter-exchange is kept watch on communication mutually, utilize.
Network manager is logically cut apart network, in the network that is made up of switch, constitutes a plurality of virtual LAN (VIAN (Virtual Local Area Network).Network manager is specified the VLAN of (definition) access destination in order to control the visit to each VLAN at user terminal to the port of each switch.In addition, owing in being connected to the port of switch, make the bag of a plurality of VLAN overlap transmission, so network manager must be specified a plurality of VLAN to the port that is connected in switch.
When the network that the switch that the redundant system control protocol is applicable to by assigned vlan constitutes; Network manager is set 2 switches that constitute the redundancyization switch and a plurality of switches that are connected in the redundancyization switch for the whole VLAN that become the redundancyization object.Network manager need be set as follows: identical VLAN is distributed corresponding to the port in current use system path with corresponding to the port in standby system path, even if to use which identical VLAN capable of using in current use system path and standby system path.
Network manager is new when importing switch in network, must set the new new switch that imports and established inter-exchange annexation, reach the port that new switch is possessed and reach the VLAN that has established each port assignment that switch possesses.And when in the redundant system control protocol, using GSRP, the necessary planned network structure of network manager is directly to connect and compose 2 switches of redundancyization switch.
In addition; Through append new switch to network; When the existing network that is not redundancy structure was altered to the network of redundancy structure, network manager must change the setting of establishing switch that becomes the redundancyization object, the setting and the setting of establishing the whole switches that are connected on switch and the new switch that becomes the redundancyization object of new switch.
Specifically, network manager need be set the annexation and the VLAN of inter-exchange to these whole switches.Therefore, along with network size becomes big, the quantity of the switch that network manager must change setting also increases.Therefore, along with network size becomes big, the workload of network manager increases, and for network manager, is difficult to change the setting of switch.
The 1st purpose of the present invention is, even in sweeping network, also can easily reduce the workload that network manager change switch is set, and in network, import redundancy structure.
In addition, in sweeping network, the workload of setting because of network manager change switch increases, and increases so the network manager mistake is set the probability of switch.In addition, the mistake of this switch is set becomes the essential factor that reduces network availability.
The 2nd purpose of the present invention is, even in sweeping network, also can reduce the workload that network manager change switch is set, and reduces the mistake setting of the switch when changing network configuration.
Summary of the invention
The representational mode according to the present invention; It is a kind of supervisory computer; Possess the processor that carries out calculation process, be connected in the storage part of said processor and be connected in the interface of said processor; Be connected in network through said interface, management constitutes a plurality of switches of said network, and it is characterized in that: said network is to hold the network of being discerned one or more VLAN of a plurality of switches that constitute said network by vlan identifier uniquely; And; Said network is divided current use system path and standby system path by constituting the first right switch of redundancyization and second switch in said a plurality of switches, said storage portion stores Port Management information, the identifier of the VLAN of the annexation of said each switch of this Port Management information representation and the port assignment that possesses to said switch; Said processor is through upgrading the Port Management information of said first switch; With port among the port that possesses to said first switch, that be connected in the linking objective switch that connects said first switch, be connected in the VLAN of the port assignment of said first switch in the port that divides the said linking objective switch of orientation to possess, it is right to constitute said redundancyization.

Then; CPU 24 with linking objective switch 300 corresponding port information management tables 213 in registration in the port identifiers 21301 that comprises identifier, in the consistent linking objective node identifier 21302 that project comprised, register the identifier of the new switch 300 that comprises in the link information with the identifier of the port that is connected in new switch 300.In the linking objective port identifiers 21303 that CPU 24 comprises in this project, the identifier of the new switch 300 that comprises in the registration link information.In the linking objective port identifiers 21303 that CPU 24 comprises, be connected in the identifier of the port of linking objective switch 300 in the port that the new switch 300 that comprises in the registration link information possesses in this project.
And CPU 24 carries out the redundancy condition criterion shown in Figure 35 and handles (S3912) between new switch 300 and linking objective switch 300.
In the processing of S3912, when being judged to be new switch 300, advance to S3905 with linking objective switch 300 and redundancyization term harmonization.In addition, in the processing of S3912, when at least one side and redundantization condition were inconsistent in being judged to be new switch 300 and linking objective switch 300, CPU 24 notified the manager 1 this situation.
The processing of S3905 is described in addition, particularly.
CPU 24 carries out the redundancy structure shown in Figure 15 and generates processing.In addition; Under the situation of this execution mode; Because constituting 2 switches 300 of redundancyization switch is new switch 300 and the linking objective switch 300 that is connected in new switch 300; So in a switch that constitutes the redundancyization switch, needn't set another switch 300 and the annexation that is connected in the linking objective switch 300 of this another switch 300 of constituting the redundancyization switch.Therefore, do not carry out the processing that the redundancyization structure generates the S1802～S1805 that handles.
In the processing of S1801, CPU 24 obtains the identifier of new switch 300 and is connected in the identifier of the linking objective switch 300 of new switch 300 from the link information that receives.In addition, the identifier of the switch 300 that CPU 24 will obtain remains S0, and the identifier of another switch 300 of obtaining is remained S.
In addition, for the processing of S1806～S1809, since identical with execution mode 1, so omit explanation.
Like this; According to embodiment of the present invention 3; Manager 1 is when being connected in the switch of standby system on the existing network that is made up of switch again; Make redundant system control effective network between the standby system switch that can be formed in existing current use system switch automatically and newly be equipped with, have when the required time of redundancy structure network is constructed in shortening, the VLAN that can reduce switch sets wrong effect.
(execution mode 4)
Below, with Figure 37 and Figure 38 execution mode 4 of the present invention is described.
Execution mode 4 is management servers 2 when the redundancy indication that receives from manager 1, and retrieval constitutes 2 switches 300 (redundancyization to) of redundancyization switch, the execution mode of generation redundancyization switch from the switch 300 that constitutes network 4.
Figure 37 is the precedence diagram during planned network on the management server 2 of embodiment of the present invention 4.
Because the processing of the processing of the processing of S4001～4003 and S4005～4011 and the S3701～S3703 of the flow chart shown in Figure 34 of execution mode 2 and the processing of S3705～S3711 are identical, so the omission explanation.
Manager 1 will retrieve the right indication input manager server 2 (S4004) of redundancyization from the switch 300 that constitutes network 4.
CPU 24 is in case the indication of input redundancyization is then retrieved redundancyization to (S4005).In addition, to retrieval process, details is described for redundancyization with Figure 38.
And 24 couples of CPU carry out the redundancyization structure as redundancyization to 2 switches 300 that are retrieved and generate processing (S4005).
Specifically, CPU 24 carries out the redundancy structure shown in Figure 15 and generates processing.In addition; Under the situation of this execution mode; Because constituting 2 switches 300 of redundancyization switch is as 2 switches 300 of redundancyization to being retrieved; So in a switch that constitutes the redundancyization switch, needn't set another switch 300 and the annexation that is connected in the linking objective switch 300 of this another switch 300 of constituting the redundancyization switch.Therefore, do not carry out the processing that the redundancyization structure generates the S1802～S1805 that handles.
In the processing of S1801, CPU 24 obtains as redundancyization to the identifier of a switch 300 being retrieved and as the identifier of redundancyization to another switch 300 of being retrieved.In addition, CPU 24 will remain S0 to the identifier of a switch 300 being retrieved as redundancyization, will remain S to the identifier of another switch 300 of being retrieved as redundancyization.
In addition, for the processing of S1806～S1809, since identical with execution mode 1, so omit explanation.
Figure 38 is the flow chart of the redundancyization of embodiment of the present invention 4 to retrieval process.
At first, CPU 24 obtains the identifier (S4101) of 2 switches 300 from the switch 300 that constitutes network 4.In addition, the identifier of a switch remains S1 in 2 switches 300 that CPU 24 will obtain, and the identifier of another switch 300 is remained S2.
Then, CPU 24 retrievals are by the switch 300 pairing port information admin tables 213 (S4102) of 2 identifiers (S1 and the S2) identification that obtains.
And, judge by the switch of 2 identifiers (S1 and the S2) identification that obtains 300 whether with the redundancy term harmonization (S4103) shown in Figure 35.
In the processing of S4103, when switch of being discerned by 2 identifiers (S1 and S2) of obtaining 300 and redundancyization term harmonization, CPU 24 establishes redundancyization to the retrieval process success, finishes redundancyization to retrieval process.
In addition, in the processing of S4103, in by the switch 300 of 2 identifiers (S1 and S2) of obtaining identification at least one when inconsistent, CPU 24 judges whether in addition existence becomes the switch 300 (S4104) of redundancyization to candidate with redundantization condition.
Specifically, whether CPU 24 judges the processing of the combination of the switch 300 that constitutes network 4 being carried out S4103.
In the processing of S4104, be judged to be other existence when becoming redundancyization to the switch 300 of candidate, CPU 24 obtains the identifier (S4105) of 2 switches 300 of the identifier different combinations of 2 switches 300 obtaining in the processing that becomes with S4101.In addition, the identifier of a switch 300 remains S1 again in the identifier of 2 switches 300 that CPU 24 will obtain, and the identifier of another outer switch 300 is remained S2 again.
And the switch 300 of identifier (S1 and the S2) identification that obtains in 24 pairs of processing through S4105 of CPU is carried out the processing of S4103.
Thus; Because manager 1 is only to the right indication of management server 2 input retrieval redundancyizatioies; Management server 2 retrieval redundancyizatioies are right; Automatically generate network redundancyization and the setting content of each required switch 300 upgrades the setting content of each switch 300, so can reduce manager 1 workload.
And, in this execution mode, whole combinations of the switch 300 that constitutes network 4 are carried out the processing of S4103., CPU 24 also can carry out the processing of S4103 to the combination of direct-connected switch 300.
Specifically, CPU 24 selects a switch 300 in the processing of S4101 and S4105, selects to be directly connected in the switch 300 of the switch of selecting 300.And CPU 24 obtains the identifier of 2 switches 300 of selection.
And CPU 24 judges the processing of whether whole combinations of direct-connected switch 300 being carried out S4103 in the processing of S4104.
Thus,, direct-connected switch 300 is carried out the processing of S4102～S4107, so can reduce the processing load of CPU 24 owing to, do not carry out the processing of S4102～S4107 for whole switch 300.
Utilizability on the industry
The present invention can be applicable to management server with network, especially applicable to the Network Management server of managing redundantization.
