Fig. 2 schematic diagram of the present invention.
Embodiment
In order to better understand technical scheme of the present invention, below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, communication network generally comprises: industrial computer, and industrial computer connects three-tier switch by core switch or router, and three-tier switch connects two layers of access switch, and two layers of access switch connect terminal equipment.
Industrial computer for scanning two layers of access switch, three-tier switch and terminal equipment, to obtain their IP address relevant information.Three-tier switch uses as terminal computer gateway in a network or uses as routing device.Only be used to provide the switch connecting terminal and be called two layers of access switch and Layer 2 switch.
As shown in Figure 2, a kind of network terminal address based on switch technology batch binding method, comprises step:
S1, obtains ARP table, mac address table, physical interface, three layers of VLAN and two layer vlan information; Be connected to the network equipment by snmp Simple Network Management Protocol, telnet and ssh mode, read the information such as ARP table, mac address table, physical interface, VLAN virtual interface, two layers of VLAN of operational outfit.Read exchanger information by snmp agreement, some information (such as switch ports themselves binding information) leaves in privately owned key assignments, cannot directly read, and can only be obtained by the mode of Telnet.Some switches only allow ssh mode to log in, and what have can only be logged in by telnet mode, so the needs in order to gather necessary information, three kinds of modes need to adopt, and the information not so gathered is just comprehensive not.The network equipment mainly refers to Ethernet switch, also has a small amount of ethernet router.Operational outfit refers to the equipment during network uses that is connected to, and does not comprise and moves back fortune and stock equipment.In order to gather these IP address relevant informations, need a continuous scan for networks switch of equipment and terminal equipment, our this scheme be adopt be industrial computer, be therefore that this industrial computer removes interconnection network equipment by snmpssh or telnet.
S2, decomposes three layers of vlan information data, obtains the IP address range that can use, and forms the IP address of terminal table that can distribute.The VLAN virtual interface data of three-tier switch are decomposed, obtains the available IP-addresses scope of this VLAN, and interface, subnet, broadcast address are marked, form assignable IP address of terminal table.VLAN virtual interface is created on three-tier switch, the gateway of namely set at ordinary times computer, generally comprise IP address and mask two parts, such as interface IP address 192.168.1.1, subnet mask is 255.255.255.0, just can know that the IP address range that can be used for terminal computer to use is 192.168.1.2---192.168.1.254 by this, other address can not be used to computer.
S3, contrast mac address table and ARP table, obtains IP, MAC and the switch ports themselves information of terminal under each physical interface; Contrast with the ARP table of three-tier switch at the mac address table of two layers of access switch, obtain IP, the MAC of terminal under each physical interface, switch ports themselves information.ARP table on three-tier switch comprises IP, the MAC of each terminal computer, the physical interface number of three-tier switch, vlan number information, the mac address table of access switch only comprises MAC Address, vlan number, the layer 2-switched physical interface number of terminal computer, their MAC Address of two are consistent, and this just can get up two information association.
S4, customization access templates, digital independent template and address binding command template; For realization is to the reading of exchange data and control, need the access templates formulating snmp, telnet, ssh, digital independent template, address binding command template.Access switch needs IP address, account, password three information, and in same network, a lot of network equipment account number cipher may be divided into several possibility, and formulating template is in order to streamlining management, and not so each switch will be registered.
The bind command of different model switch may be had any different, and therefore will distinguish model and issue different bind command to switch, and formulating template can treat with a certain discrimination.
The order example of bind address: arpstatic192.168.1.5500-06-ff-a1-45-33 on three-tier switch.The order example of bind address: ambind192.168.1.5500-06-ff-a1-45-33intfacee1/0/33vlan3 on Layer 2 switch
This is the bind command signal of a kind of model switch of wherein a kind of brand, and changing another equipment may just make mistakes, and uses another one command format, just needs to do a template, deacclimatizes.Will comprise following information in template: equipment brand, model, command template just becomes: arpstatic [IP] [mac].
S5, after carrying out identity examination, generates terminal address binding directive script and instruction is issued to switch, carry out batch binding to the terminal equipment of access network.
After identity examination is carried out to the network-termination device of access, utilize the information read to generate terminal address binding script, be issued to switch according to reservation template, carry out batch binding.Untapped IP address and switch physical interface use address to take template and bind, and prevent unauthorized terminal from accessing.
So-called identity is screened, open a computer network in enterprise network and need submit applications form or flow process, legal end user's information, device mac address is had in form, just can be identified in this equipment access to network, identify MAC Address will with application consistent, and access place also consistent with position.Generating bind command script is that the model of Layer 2 switch and the three-tier switch connected according to terminal equipment is determined, perform template according to model before, by the access interface of acquisition terminal, MAC and binding template, program on industrial computer just can generate a command list (CLIST), the binding push-botton operation of network manager on operation screen, be exactly behind these orders are issued to relevant switch to get on execution in fact, and the execution result of returning can be read.
Address takies template: the template being exactly in fact binding invalid IP and MAC, cross if IP address is bound in three-tier switch, other equipment just cannot employ, network manager has accounted for all available IP addresses descend, and just can play and prevents someone from guessing at random the online of IP address or falsely use others' IP address online.
Whether successful S6, detect binding, if success, terminate, if unsuccessful, repeat above-mentioned steps.Read three layers, Layer 2 switch address binding data according to reservation template, whether inspection binding is effective.Because network equipment brand and model is different, the binding terminal Computer IP read on switch is not identical with the order of MAC information yet, needs to formulate a command template according to model yet and goes to read.Such as have plenty of show order, have plenty of display order.
Manually be remotely logged into switch to get on fill order, just can see that whether command syntax was correct at that time, and allow program go execution there is no this reciprocal process, therefore after executing bindings, go to read equipment, judge whether binding task has run succeeded according to the configuration parameter returned.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
