In the specific implementation of step S809, if secondary equipment 704 sends the second configuration file to second network equipment The mode of packet is: receive from second network equipment and for request second network equipment configuration file message and then The scheme of the second configuration file packet is sent to second network equipment, then the message between secondary equipment 704 and second network equipment Interactive process can be found in the content of the embodiment of corresponding diagram 5, and difference is: devices to be configured is changed to second level by overlay device Equipment 704, request equipment change are three-stage apparatus 706 or first device 702, and according to the rank of second network equipment, adjustment The configuration file for including in second configuration file packet.

Another embodiment of the application also discloses a kind of configuration method of network equipment.In the present embodiment, devices to be configured It can be divided into two kinds of roles: logic root device and agent equipment；Wherein, the whole net configuration file packet in cloud management controller is obtained The network equipment becomes logic root device, logic root device preserves whole net configuration file after to the activation of itself configuration file Packet.Agent equipment only has the configuration file of oneself, and the message for being used to request configuration for equipment will to be requested to send, agency arrives Logic root device is also used to the message for being used for response for sending logic root device, agency to request equipment.

Based on this, in the configuration method of the network equipment disclosed in the present embodiment, the configuration method of logic root device, referring to figure 9, comprising: step S901~S909.

Wherein, logic root device is overlay device or is non-overlay device, the specific implementation of step S901~S903 Cheng Jun can be found in the content of the embodiment of corresponding diagram 2.

In the specific implementation of step S904, cloud management controller is directed to the request message of configuration file, regardless of logic Whether root device is overlay device, and generation is whole net configuration file packet, the configuration text including all-network equipment in network Part.

In the specific implementation of step S908, logic root device is after receiving whole net configuration file packet, from whole net The configuration file of second network equipment is extracted in configuration file packet, wherein second network equipment includes in network except logical root is set Any one network equipment other than standby.

Since the network equipment that logic root device can only be connected to it sends configuration file, if second network equipment is and patrols When collecting the network equipment of root device connection, i.e. second network equipment is some network equipment in the third network equipment, that is patrolled The configuration file for second network equipment that volume root device is sent to the third network equipment, comprising: logic root device is to third network The configuration file for the third network equipment that equipment is sent.

If when the network equipment that second network equipment is not connect with logic root device, being set in network with third network Any one network equipment in the standby branch of a network for root node, that illustrates that the third network equipment is agent equipment, that logic The configuration file for second network equipment that root device is sent to the third network equipment, comprising:

The derivation configuration file for second network equipment that logic root device is sent to the third network equipment；

Wherein, the value and the value phase of the configuration file of second network equipment of second network equipment derived from configuration file Together, the difference of the two is, in the derivation configuration file of second network equipment, it includes that meaning configures for response that Type value, which is removed, Value further includes the value that meaning is agency.

In the specific implementation of step S909, logic root device sends matching for second network equipment to the third network equipment File is set, can be after the configuration file for extracting second network equipment, is directly sent to the third network equipment, it can also be with It is to receive from the third network equipment and after being used to request the message of configuration file of second network equipment, to third net Network equipment is sent.

The third network equipment is come from and for asking to illustrate logical root equipment in reception with a specific embodiment below After the message for seeking the configuration file of second network equipment, the configuration file of second network equipment is sent to the third network equipment Scheme, and in this scenario, the network equipment that second network equipment is not connect with logic root device, with third in network The network equipment is any one network equipment in the branch of a network of root node.

Referring to Fig. 1 and Figure 10, in the present embodiment, by taking the third network equipment is secondary equipment 104 as an example, to secondary equipment 104 by agent equipment-first device 102, and the process that configuration file is obtained from logic root device-overlay device 101 carries out Explanation.Specifically, including:

S1001, secondary equipment 104 send multiple first two-layer protocol messages using multiple ports.

Wherein, wherein secondary equipment 104 sends first two-layer protocol message, the one or two layer of association using a port Message is discussed for requesting configuration.Secondary equipment 104 is request equipment, and port can be separately connected other network equipments, need First two-layer protocol message is successively sent using the port in connection status, to determine to be attached with first device 102 Port.Also, secondary equipment 104 sends the specific implementation process of the first two-layer protocol message, reference can be made to the implementation of corresponding diagram 5 In example, the content of step S501, details are not described herein again.

S1002, first device 102 generate first and derive from two-layer protocol message according to the first two-layer protocol message.

Wherein, the equipment sequence of secondary equipment 104 can be carried in the first two-layer protocol message that secondary equipment 104 is sent Number.First device 102 receives the first two-layer protocol message, and the secondary equipment 104 carried according to the first two-layer protocol message is set Standby sequence number or secondary equipment 104 send the port of the first two-layer protocol message, judge that itself does not save secondary equipment 104 configuration file illustrates itself then for agent equipment, then generates first and derive from two-layer protocol message.

For the first two-layer protocol message generated using LLDP agreement, first device 102 receives the first two-layer protocol report Text adds Subtype again as 3 and (sets containing for Subtype3 for the value for the Subtype that the message recombinant meaning is agency Justice is proxy information), it forms first and derives from two-layer protocol message, the i.e. value of the Subtype of the first derivation two-layer protocol message For Subtype1 and Subtype3.Also, the first derivation two-layer protocol message can also carry the equipment sequence of secondary equipment 204 Row number.

Also, according to other two-layer protocols, for example, the agreement based on BPDU encapsulation, the derivation of uplink or downlink In message, the occurrence of Type also adds the value that meaning is agency again.

S1003, first device 102 send first to overlay device 101 and derive from two-layer protocol message.

After first device 102 requests itself configuration file to overlay device 101, itself and overlay device 101 will record Connectivity port receives the first two-layer protocol message of the transmission of secondary equipment 104 in first device 102, and generates first and derive from After two-layer protocol message, first is sent using the first device 102 of record and the connectivity port of overlay device 101 and derives from two layers of association Discuss message.

It is using the end also, in the step of following reflection first device 102 and overlay device 101 interact Mouthful, just do not illustrate one by one.
