Fig. 3 is the flow chart of MAC Address distribution method embodiment three of the present invention, and as shown in Figure 3, present embodiment provides a kind of MAC Address distribution method, can specifically comprise the steps:
Step 301, when device start, device-to-server sends MAC Address and distributes request.
Present embodiment is primarily aimed at the scene of having only equipment component enable position MAC in the whole network, and position MAC herein 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.Server herein can be specially Dynamic Host Configuration Protocol server.
Pile up scene by 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 the 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 and switch 2 couple together by piling up cable, form a virtual switch, 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, namely on the virtual switch.In the present embodiment, the virtual switch that has only switch 1 and switch 2 to form is enabled position MAC, and 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 is before access network, make a copy of the MAC Address of this switch earlier, the configuration file of this MAC Address correspondence 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 by its upstream equipment, after device-to-server sends MAC Address distribution request, the upstream equipment of this equipment is by starting DHCP Snooping function, the MAC Address that equipment is mail to server distributes request to intercept, after listening to MAC Address distribution request, add the positional information of this equipment to MAC Address and distribute in the request.Fig. 5 is the network architecture schematic diagram among the MAC Address distribution method embodiment three of the present invention, and as shown in Figure 5, switch C is by its upstream equipment, and namely 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, distributes the positional information of adding switch C in the request in this MAC Address.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 the address information of switch D and switch D receive MAC Address and distribute request.
Upstream equipment distributes request to intercept in the MAC Address that equipment is mail to server, and after this MAC Address is distributed the positional information of adding equipment in the request, distributes request to send to server the MAC Address after the point of addition information.Be example with above-mentioned Fig. 5 still, switch D adds the positional information of switch C to MAC Address and distributes in the request, specifically positional information is added in option 82 fields in the MAC Address distribution request and passes to Dynamic Host Configuration Protocol server.
Step 304, server is the devices allocation MAC Address according to positional information, and MAC Address is returned to equipment.
Server is receiving after MAC Address distributes request, be this devices allocation MAC Address according to the positional information of the equipment that wherein carries, and the MAC Address of distribution is returned to equipment.
Equipment with the MAC Address of the distributing system's MAC Address 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 the equipment in the present embodiment does not re-use factory settings or revises by hand, the MAC Address that equipment uses is distributed 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 to choose from the switch that piles up, and selects the MAC Address of host exchange as the MAC Address of 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 the new host exchange MAC Address as virtual switch, at this moment, 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 certain switch in the pile system as the MAC Address of this virtual switch, but distribute a MAC Address according to the positional information of this virtual switch for it, then no matter any one switch in the pile system changes, for the switch A of outside and switch b, all can not exert an influence, then need not interrupt network and consult again.
In the automatic deployment scenario of beginning, in the prior art, because the MAC Address of configuration file and equipment is strong binding, if mistake is placed in the position of equipment, for example, be deployed in the switch actual deployment of corridor A in corridor B in the original plan, 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 error of equipment.And in the present embodiment, removed the MAC Address of equipment and the unique corresponding relation of equipment, and directly come to be the devices allocation MAC Address according to the positional information of equipment, then can solve the above-mentioned problems in the prior art.
The MAC Address distribution method that present embodiment provides, when device start, device-to-server sends MAC Address and distributes request, the upstream equipment of equipment distributes the positional information of interpolation equipment in the request and is delivered to server in MAC Address, and server is the MAC Address of devices allocation correspondence according to positional information; Present embodiment distributes MAC Address according to the equipment present position, but not the fixedly MAC Address of using 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, because the MAC Address of equipment is obtained automatically according to its positional information, therefore also need not interrupt network and consult again; 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 namely 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 the network architecture schematic diagram among the MAC Address distribution method embodiment four of the present invention, and as shown in Figure 7, the service equipment in each rack is by 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 divided into different departments or functional area according to the zone.The tree of convergence step by step that is planned to owing to data center then can carry out the distribution of MAC Address by 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 grade of equipment, and as TOR A, TOR A1 etc., the EOR switch that connects the TOR switch is the 2nd grade of equipment, as EOR A, EOR B, EOR C, the convergence switch that connects the EOR switch is 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, it is the MAC Address prefix and the 0th that 3rd level equipment need get access to this equipment, 1, the MAC Address range of distribution of 2 grades of equipment, the 2nd grade of equipment need get access to the MAC Address prefix and the 0th of this equipment, the MAC Address range of distribution of 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 Address again, then need not to obtain MAC Address prefix and MAC Address range of distribution.
In this step, distribute interval transmission step by step in order to realize MAC Address, newly-increased a kind of MAC rule distribution protocol when device start, sends MAC Address to its upstream equipment earlier and distributes request, i.e. its MAC Address of upstream device request is distributed interval.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 that the equipment that receives sends is distributed request, the positional information of distributing this equipment of acquisition request according to this MAC Address, upstream equipment specifically distributes the employed incoming interface of request to obtain the positional information of described equipment according to receiving MAC Address, and positional information herein can be specially upstream equipment and receive the interface message that this MAC Address is distributed the employed incoming interface of request.
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 is receiving after MAC Address that this equipment sends distributes request, 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.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 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 distributes the interface message of the employed incoming interface of request to generate the MAC Address prefix of this equipment according to self MAC Address prefix, the mac address range of this equipment, upstream equipment reception MAC Address.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, the MAC Address that this upstream equipment uses the port one of self to receive equipment is distributed request (being that interface message is 01), and then upstream equipment is that the MAC Address prefix of this devices allocation can be 0x0001-0001-01xx; If the MAC Address that this upstream equipment uses the port 2 of self to receive equipment is distributed request (being that interface message is 02), 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 is distributed 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 select any one MAC Address as the MAC Address of self from this interval, and this interval is a set of the optional MAC Address of this equipment.And the number of the MAC Address that comprises in the MAC Address interval of the mac address range of equipment for the MAC Address prefix representative of this equipment.Also can carry simultaneously the MAC stratum level of this equipment in response message, the MAC stratum level of indication is this equipment residing rank in data center herein, as, it is the 1st grade of equipment or the 2nd grade of equipment.Be example with above-mentioned Fig. 7, 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 as 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 select a MAC Address as the MAC Address of self from the MAC Address interval of this MAC Address prefix representative, when being 0x0001-0001-01xx as the 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 0x0001-0001-0111 as the MAC Address of self usually.
