Wherein, the model of obtaining the network equipment can realize by technological means of the prior art;
Particularly, NM server gets after the model of the network equipment, by the type of the obtained network equipmentNumber contrast with the unit type prestoring, in the unit type prestoring, there is the obtained network equipmentIn the situation of model, according to the corresponding relation of the unit type prestoring and device type, identify data centerServer physical host and switch; In the unit type prestoring, do not there is the obtained network equipmentIn the situation of model, determine that this network equipment is user terminal;
Be switch at the edge device identifying, send inquiry to this switch and whether supportVirtualized order, receiving after the virtualized reply of support, determines that this switch is access switch,Otherwise be convergence switch;
The ARP table of the access switch that step 302, NM server basis identify,Determine and the server physical host of the interface communication of described access switch, and set up described access exchangeThe corresponding relation of the interface of machine and determined server physical host;
The clothes of the interface communication of definite in step 302 and described access switch have been shown in Fig. 4 particularly,The processing procedure of business device physical host, this process comprises:
Step 3021, NM server are logined the access switch identifying, according to this access switchInterface message in ARP table, obtains the model of the network equipment direct-connected with the interface of this access switch;
Wherein, login access switch, obtain the ARP table of access switch and obtain the network equipmentModel can realize by prior art means;
Step 3022, judge and whether the network equipment that the interface of access switch is direct-connected is edge device,Be defined as in the situation of edge device, process and proceed to step 3023, otherwise, process and proceed to step 3024;
Wherein, judge that the processing that direct-connected device is edge device comprises: by the model of obtained direct-connected deviceContrast with the unit type prestoring, in the unit type prestoring, there is the type of obtained direct-connected deviceNumber situation under, according to the corresponding relation of the unit type prestoring and device type, determine that this direct-connected device isServer physical host or switch; In the unit type prestoring, do not there is the type of the obtained network equipmentNumber situation under, determine that this network equipment is user terminal;
