In order to solve the problem that a server cannot be quickly accessed to a network in the related art, the embodiment of the application also provides a network access system, which comprises an access model management module, an IP address management module, a switch port management module and a switch configuration issuing module.
When a server access requirement exists, a network administrator selects a corresponding access model in a server access model management module, and if the corresponding model does not exist, an access model is added and registered in the module and selected; the IP address management module distributes server addresses according to the model; the switch port management module allocates spare ports of the switch according to the server access model and generates port configuration by combining the allocated IP addresses, and if the port allocation rule corresponding to the server access model does not exist, a corresponding rule is established by network management; and the switch configuration issuing module issues the configuration to the switch according to the switch port and the configuration content, so that the server is accessed to the network. Each server access model only needs to manually define a template once, and IP allocation, port allocation, configuration generation and issuing can be automatically completed subsequently.
The model management module is used for managing a server access model, such as a server access model A, and comprises a server, wherein 2 production network lines are respectively connected with a pair of production switches to perform link dynamic aggregation; 2 out-of-band network wires are respectively connected into a pair of out-of-band switches to perform dynamic link aggregation; one ilo network cable is connected to one out-of-band switch, single port.

And the switch port management module is used for recording available access switch information in the network and the port use condition of the switch downlink server. If 2 production switches and 2 out-of-band switches belong to one logic unit, the service can be provided for an adaptive server access model. Defining a port allocation rule of the access model, such as model 1, wherein the port allocation rule is as follows: 2 production ports are needed, the ports on 2 production switches are traversed from small to large respectively, the spare port with the smallest port number is selected, and the spare port is distributed to the equipment on line at this time; 2 out-of-band ports are needed, the ports on 2 out-of-band switches are traversed from small to large respectively, and the spare port with the minimum port number is selected and allocated to the equipment on line at this time; a ilo port is needed, the port of 2 out-of-band switches is traversed from large to small, and the spare port with the largest port number is selected and allocated to the on-line device. Defining port configuration production rules, such as model 1, wherein the production ports are 2 port configuration dynamic port aggregation, and 192.168.1.1 corresponds to vlan; the out-of-band port configures dynamic port aggregation for 2 ports, and 192.168.2.1 is released to correspond to vlan; ilo is single ended, release 192.168.3.1 corresponds to vlan.
And the switch configuration issuing module is used for issuing the configuration to the actual switch equipment according to the information of the switch port management module so as to connect the server network.
By applying the system provided by the embodiment of the application, the automatic server access configuration can be provided, so that the network change is safer and more efficient; a primary template can be defined, and subsequent automatic configuration generation is performed, so that the manual repeated workload is reduced; the automatic configuration gives consideration to flexibility, and can meet the requirement that different servers of the data center access the network through the access model.
