Step 301, when device start, device-to-server sends the MAC Address request for allocation.
Present embodiment is primarily aimed at the scene of having only equipment component enable position MAC in the whole network, and the position MAC here is that the MAC Address of equipment is to distribute according to the position of equipment.For example in piling up scene, have only stack equipment enable position MAC, in the automatic deployment scenario of beginning, have only the switch enable position MAC in the new access network, the MAC Address that all the other equipment can still adopt original equipment vendors to set.The server here can be specially Dynamic Host Configuration Protocol server.
Pile up scene through a plurality of switches are coupled together, form a virtual switch and manage, the most of switch in the existing equipment vendors all supports to pile up function.The advantage of piling up is a management maintenance of being convenient to switch, and disturbance switching and active/standby backup function fast are provided.Fig. 4 is the schematic network structure of pile system among the MAC Address distribution method embodiment three of the present invention; As shown in Figure 4; Switch 1 couples together through piling up cable with switch 2, forms a virtual switch, and switch A and switch b are only seen virtual switch in network; Be equivalent to switch A and switch b and only be connected to a switch, promptly on the virtual switch.In the present embodiment, have only switch 1 and the virtual switch that switch 2 is formed to launch position MAC, switch A and switch b then can adopt the MAC Address of factory settings.
In the automatic deployment scenario of beginning; In order to reduce the configuration effort of newly added equipment, newly-increased switch was made a copy of the MAC Address of this switch earlier before access network; The corresponding configuration file of this MAC Address of record in server; After the switch access network, switch obtains configuration file according to MAC Address from server, realizes configuration automatically.In the present embodiment, can have only the switch enable position MAC in the new access network, the MAC Address that all the other equipment can still adopt original equipment vendors to set.
Because equipment is connected in the network through its upstream equipment; After device-to-server sends the MAC Address request for allocation; The upstream equipment of this equipment is through starting DHCP Snooping function; The MAC Address request for allocation that equipment is mail to server is intercepted, and after listening to the MAC Address request for allocation, the positional information of this equipment is added in the MAC Address request for allocation.Fig. 5 is for the network architecture sketch map among the MAC Address distribution method embodiment three of the present invention, and is as shown in Figure 5, and switch C is through its upstream equipment, and promptly switch D is linked in the network, and then is connected with Dynamic Host Configuration Protocol server.Switch C is when passing through switch D to Dynamic Host Configuration Protocol server request MAC Address, and switch D starts DHCP Snooping function, in this MAC Address request for allocation, adds the positional information of switch C.Wherein, The positional information of equipment comprises the address information of its upstream equipment and the interface message that equipment inserts this upstream equipment; For the switch C among Fig. 5, positional information comprises employed interface message when address information and the switch D of switch D receive the MAC Address request for allocation.
Upstream equipment is intercepted in the MAC Address request for allocation that equipment is mail to server, and after in this MAC Address request for allocation, adding the positional information of equipment, the MAC Address request for allocation after the point of addition information is sent to server.Be example with above-mentioned Fig. 5 still, switch D adds the positional information of switch C in the MAC Address request for allocation to, specifically positional information is added in option 82 fields in the MAC Address request for allocation and passes to Dynamic Host Configuration Protocol server.
Server is this devices allocation MAC Address according to the positional information of the equipment that wherein carries after receiving the MAC Address request for allocation, and the MAC Address that distributes is returned to equipment.
Equipment with the system MAC Address of the MAC Address that distributes as equipment, and carries out follow-up protocol negotiation according to this system's MAC Address after receiving the MAC Address that server returns.Be the MAC Address that equipment in the present embodiment does not re-use factory settings or free hand modification, the MAC Address that equipment uses distributes according to the positional information of equipment self.
In the pile system scene; Because pile system is many switches to be coupled together form a virtual switch; Therefore; In the prior art, the MAC Address of virtual switch is from the switch that piles up, to choose, and selects the MAC Address of the MAC Address of host exchange as virtual switch usually.When the host exchange in the pile system shifts out from pile system or breaks down; Pile system is reselected new host exchange; And with the MAC Address of new host exchange MAC Address as virtual switch; At this moment, the switch A among Fig. 4 finds that with switch b the switch that is connected changes, and then needs interrupt network to consult talk various network protocols again.And in the present embodiment; Do not re-use the MAC Address of the MAC Address of certain switch in the pile system as this virtual switch; But distribute a MAC Address for it according to the positional information of this virtual switch; Then no matter any one switch in the pile system changes, and for the switch A of outside and switch b, all can not exert an influence, and then need not interrupt network and consults again.
In the automatic deployment scenario of beginning, in the prior art, because the MAC Address of configuration file and equipment is strong the binding; If mistake is placed in the position of equipment, for example, the switch actual deployment that is deployed in corridor A in the original plan is in corridor B; And server still issues corresponding configuration file according to its MAC Address; Because configuration file is relevant with the position of equipment, when make a mistake in the position of equipment, then can cause the configuration of devices mistake.And in the present embodiment, removed the unique corresponding relation of the MAC Address and the equipment of equipment, and directly come to be the devices allocation MAC Address according to the positional information of equipment, then can solve the problems referred to above that exist in the prior art.
The MAC Address distribution method that present embodiment provides; When device start; Device-to-server sends the MAC Address request for allocation; The upstream equipment of equipment adds the positional information of equipment and is delivered to server in the MAC Address request for allocation, server is the corresponding MAC Address of devices allocation according to positional information; Present embodiment distributes MAC Address according to the equipment present position, but not the fixedly MAC Address that uses equipment vendors to set, than existing techniques in realizing to equipment flexibly and unified management, improved the maintainability of equipment; And when equipment in the pile system connects the appearance variation,, therefore also need not interrupt network and consult again because the MAC Address of equipment obtains automatically according to its positional information; When misplacing appears in the position of equipment in the automatic deployment scenario of beginning, still can get access to configuration file accurately.
Fig. 6 is the flow chart of MAC Address distribution method embodiment four of the present invention, and as shown in Figure 6, present embodiment provides a kind of MAC Address distribution method, can specifically comprise the steps:
Present embodiment is primarily aimed at the scene of the equal enable position MAC of all devices in the whole net, and promptly all devices all distributes MAC Address according to physical location, for example in data center's scene.In data center's scene, its networking mode is generally divides different zones, and a zone comprises the multiple row rack, and every row rack comprises a plurality of racks, places a plurality of service equipments in each rack, and service equipment can for example be memory device, computing equipment etc.Fig. 7 is for the network architecture sketch map among the MAC Address distribution method embodiment four of the present invention, and is as shown in Figure 7, and the service equipment in each rack is through cabinet top (Top of Rack; Hereinafter to be referred as: TOR) switch is linked in the network of data center, and TOR converges to row end (the End of Row of row then; Hereinafter to be referred as: EOR) switch, EOR is linked on the convergence switch again.Wherein, the service equipment in the rack is different departments or functional area according to area dividing.The tree of convergence step by step that is planned to owing to data center then can carry out the distribution of MAC Address through unified agreement.
In the present embodiment, be example with above-mentioned Fig. 7, divide different ranks according to residing position level between the switch; The service equipment (not shown) of carry under the TOR switch can be used as the 0th grade of equipment; The TOR switch of carry service equipment is the 1st a grade of equipment, and like TOR A, TOR A1 etc., the EOR switch that connects the TOR switch is the 2nd a grade of equipment; Like EOR A, EOR B, EOR C, the convergence switch that connects the EOR switch is a 3rd level equipment.Wherein, 3rd level equipment is the upstream equipment of the 2nd grade of equipment, and the 2nd grade of equipment is the upstream equipment of the 1st grade of equipment, and the 1st grade of equipment is the upstream equipment of the 0th grade of equipment.Present embodiment is that upstream equipment is that upstream device distributes MAC Address; Then upstream equipment need get access to the MAC Address prefix of self and the MAC Address range of distribution of the switch of each level of hanging down; Be that 3rd level equipment need get access to the MAC Address prefix of this equipment and the MAC Address range of distribution of the 0th, 1,2 grade of equipment; The 2nd grade of equipment need get access to the MAC Address prefix of this equipment and the MAC Address range of distribution of the 0th, 1 grade of equipment; The 1st grade of equipment need get access to the MAC Address prefix of this equipment and the MAC Address range of distribution of the 0th grade of equipment; The 0th grade of equipment need not to give other devices allocation MAC Addresss again, then need not to obtain MAC Address prefix and MAC Address range of distribution.
In this step, in order to realize the transmission step by step between the MAC Address dispensing zone, newly-increased a kind of MAC rule distribution protocol when device start, sends the MAC Address request for allocation to its upstream equipment earlier, i.e. between its MAC Address dispensing zone of upstream device request.Equipment in the present embodiment distributes the equipment of MAC Address for its upstream equipment of request for it.
Upstream equipment is after the MAC Address request for allocation that the equipment that receives sends; Obtain the positional information of this equipment according to this MAC Address request for allocation; Specifically according to receiving the positional information that the employed incoming interface of MAC Address request for allocation obtains said equipment, the positional information here can be specially the interface message that upstream equipment receives the employed incoming interface of this MAC Address request for allocation to upstream equipment.
Step 603, upstream equipment is according to the MAC Address prefix of self, the MAC Address range of distribution of this equipment and the MAC Address prefix that positional information generates this equipment.
Upstream equipment generates the MAC Address prefix of this equipment according to the MAC Address range of distribution of the MAC Address prefix of the positional information of obtaining and upstream equipment and this equipment after receiving the MAC Address request for allocation that this equipment sends.Wherein, The MAC Address that the MAC Address prefix of upstream equipment can specifically be distributed according to its upstream equipment gets access to; In data center; The MAC Address prefix that is arranged in the equipment (Fig. 7 is a convergence switch) of the superiors is then disposed by the keeper, and remaining equipment is distributed by its upstream equipment respectively.For example, the MAC Address prefix of 3rd level equipment is by the 4th grade of devices allocation, and the MAC Address prefix of the 2nd grade of equipment is by the 3rd level devices allocation, by that analogy.Be that upstream equipment generates the MAC Address prefix of this equipment according to the MAC Address prefix of self, the mac address range of this equipment, the interface message of the employed incoming interface of upstream equipment reception MAC Address request for allocation.For example; The MAC Address prefix of supposing the 3rd level equipment self is 0x0001-0001-xxxx; The MAC Address range of distribution of the 2nd grade of equipment is 256; This upstream equipment uses the port one of self to receive the MAC Address request for allocation (being that interface message is 01) of equipment, and then upstream equipment is that the MAC Address prefix of this devices allocation can be 0x0001-0001-01xx; If this upstream equipment uses the port 2 of self to receive the MAC Address request for allocation (being that interface message is 02) of equipment, then upstream equipment is that the MAC Address prefix of this devices allocation can be 0x0001-0001-02xx.
Step 604, upstream equipment is carried at the equipment that returns in the response message with the MAC Address range of distribution of all upstream devices of the MAC Address prefix of this equipment and this equipment.
Upstream equipment is carried at the MAC Address range of distribution of all upstream devices of the MAC Address prefix of this equipment and this equipment and returns to the equipment that the request MAC Address distributes in the response message after generating the MAC Address prefix of this equipment.In the present embodiment; The MAC Address prefix of equipment can be used for representing that upstream equipment is the interval of the MAC Address of its distribution; Equipment can be selected the MAC Address of any MAC Address as self from this interval, this interval is a set of the optional MAC Address of this equipment.And the number of the MAC Address that is comprised in the MAC Address interval of the mac address range of equipment for the MAC Address prefix representative of this equipment.Also can in response message, carry simultaneously the MAC stratum level of this equipment, the MAC stratum level of indication is this equipment residing rank in data center here, as, it is the 1st grade of equipment or the 2nd grade of equipment.With above-mentioned Fig. 7 is example, and it is as follows that convergence switch returns to the response message of EOR A switch:
The MAC Address prefix of EOR A switch: 0x0001-0001-01xx
The MAC Address range of distribution of EOR A switch: 256
EOR A switch the MAC stratum level: 2
The MAC Address range of distribution of the 1st grade of equipment: 48
The MAC Address range of distribution of the 0th grade of equipment: 1
In the present embodiment, the form of the response message in the agreement can define like following table 1:
The form signal of table 1 response message
After equipment received the response message that upstream equipment returns, this equipment obtained the MAC Address of self according to self MAC Address prefix wherein.Particularly; Equipment can be selected the MAC Address of a MAC Address as self from the MAC Address interval of this MAC Address prefix representative; When being 0x0001-0001-01xx like MAC Address prefix when equipment; The MAC Address interval of its representative is [0x0001-0001-0100; 0x0001-0001-0111], then equipment can be selected a MAC Address in the scope from 0x0001-0001-0100 to 0x0001-0001-0111, can select the MAC Address of 0x0001-0001-0111 as self usually.
In the present embodiment; After getting access to MAC Address; If this equipment is not the 0th grade of equipment in the data center, then this equipment can be that its upstream device continues to distribute MAC Address, and distribution method and the upstream equipment of the foregoing description introduction are that the method for this devices allocation MAC Address is identical.The MAC Address range of distribution of the upstream device of this equipment is carried in the response message that it returns at upstream equipment.
In data center's scene, in the prior art, because the MAC Address of switch distributes by equipment vendors, then MAC Address has no rule, can't carry out safety or flow restriction according to MAC Address, and management maintenance is more complicated also.And in the present embodiment, because the equipment of whole net is all launched position MAC, and be that upstream device distributes MAC Address step by step by upstream equipment, adopt unified MAC address assignment rule, solved above-mentioned problem that can't the unified planning management.
The MAC Address distribution method that present embodiment provides; When device start; Equipment sends the MAC Address request for allocation to its upstream equipment; Upstream equipment generates the MAC Address prefix of equipment according to the positional information of the MAC Address range of distribution of self MAC Address prefix, equipment and equipment, and equipment obtains the MAC Address of self according to the MAC Address prefix of self; Present embodiment distributes MAC Address according to the equipment present position, but not therefore the fixedly MAC Address that uses equipment vendors to set can realize that the unified planning of MAC Address administers and maintains.
