Abstract

The device includes a detection unit, a virtual network port (VNP), a test unit, and an error-reporting unit. Through the device, the method reaches own functions. The method includes following steps: the detection unit detects whether there is management interface of an intelligent platform inside computer system; if yes, the test unit sends out a test packet from VNP; passing through virtual transmission channel, the test packet reaches to the management interface of the intelligent platform, and then returns back to VNP; the test unit makes comparison between returned information at VNP and information sent in order to obtain tested result; the test unit determines whether the tested result is abnormal; if yes, then the error-reporting unit prompts error reported.

Description

Network testing device and method

[technical field]

The invention provides a kind of network testing device and method, particularly a kind of network testing device and the method that can under the situation of unit, finish the test of network function.

[background technology]

IPMI (Intelligent Platform Management Interface) is that IPMI is to make hardware management possess the universal interface standard of new generation of " intellectuality ".The user can utilize the physical features of IPMI monitor server, as temperature, voltage, electric fan operating state, power supply supply and cabinet invasion etc.The advantage of IPMI maximum is that it is independent of CPU BIOS and OS, so the user is no matter in start still under the state of shutdown, as long as energized just can realize the monitoring to server.IPMI is a kind of standard of standard, wherein most important physical unit is exactly BMC (Baseboard ManagementController), a kind of embedded management microcontroller, it is equivalent to whole platform management " brain ", the daily record that can monitor the data of each transducer and write down variety of event by its IPMI.IPMI is a kind of extendible standard simultaneously, it has defined how monitoring hardware and transducer, control system parts and record major event, along with the application of IPMI technology in server, utilize numerous advantages of IPMI just to become particularly indispensable part in the cluster management of server admin.

Usually the IMPI of our use order testing tool is low-level MS-DOS command-line tool.This instrument is ordered BMC by the IMPI that sends hexadecimal format, compares the result that return value is judged test then.And the test of IPMI network function is in the IMPI test process very important one, tests its shortcoming with order and is: 1, device dependence.To under MS-DOS, realize the test of IPMI network function, need two machines to coordinate just can finish test, can not single-set operation.2, efficient is lower.Adopt the mode of order, can run into the conversion between the more numerical value, and must be familiar with relevant test command and return value; Trickle operate miss causes test result unusual.

[summary of the invention]

Main purpose of the present invention is to provide a kind of network testing device and the method that can finish the test of network function under the situation of unit.

For reaching above purpose, the invention provides a kind of network testing device, it is arranged in the computer system to monitor the network function of this computer system, and this device comprises a probe unit, and it is in order to survey in the computer system whether have an IPMI.This probe unit test cell that is coupled, and this test cell virtual network port that is coupled, and between virtual network port and IPMI, form a virtual transmission passage.When result of detection when having IPMI, this test cell can send a test packets self-virtualizing network port, this test packets arrives IPMI after via the virtual transmission passage, then, is back to the virtual network port again; Again by test cell with the return information of virtual network port with send information and make comparisons, to obtain test result and to be judged.This probe unit and this test cell coupling one unit that reports an error, this unit that reports an error is in the result of detection prompting that reports an error when being unusual for no IPMI or test result.

The present invention also provides a kind of network test method, and it may further comprise the steps: probe unit surveys in the computer system whether have an IPMI; When probe unit had detected IPMI, test cell sent a test packets self-virtualizing network port, via arriving IPMI behind the virtual transmission passage, then, was back to the virtual network port again; Test cell with the return information of virtual network port with send information and make comparisons, to obtain test result; Test cell judges whether this test result is unusual; When test result when being unusual, the unit that the reports an error prompting that reports an error.

Compared to prior art, network testing device of the present invention and method can be finished the test of network function under the situation of unit.In addition, when utilizing network testing device of the present invention and method to carry out the test of network function, the tester need not search the order of using with compare test, need only move test program and just know test result, and is simple to operate and efficient is higher.

[embodiment]

See also shown in Figure 1, network testing device 200 of the present invention is arranged in the computer system 100 to monitor the network function of this computer system 100, this network testing device 200 comprises a probe unit 20, and this probe unit 20 is in order to survey in the computer system 100 whether have an IPMI 300; This probe unit 20 couplings one test cell 30, and this test cell 30 couplings one virtual network port 50, and form a virtual transmission passage 400 between virtual network port 50 and the IPMI 300.Wherein, this test cell 30, sends a test packets self-virtualizing network port 50 when having IPMI 300 at result of detection, arrives IPMIs 300 via virtual transmission passage 400 backs, then, be back to virtual network port 50 again; And by test cell 30 with the return information at virtual network port 50 places with send information and make comparisons, to obtain test result and to be judged; In addition, this test cell 30 further comprises a parameter set unit 31, and it is in order to revise the parameters of network.This probe unit 20 and this test cell 30 couplings one unit 40 that reports an error, this unit 40 that reports an error is in the result of detection prompting that reports an error when being unusual for no IPMI 300 or test result.

Please in conjunction with consulting Figure 1 and Figure 2, to reach, this method may further comprise the steps network test method of the present invention by above-mentioned network testing device:

Step 201: probe unit 20 surveys in the computer system 100 whether have an IPMI 300; If have, enter step 202; If do not have, enter step 207;

Step 202: parameter set unit 31 is obtained the parameter current of network and is stored;

Step 203: parameter set unit 31 is modified as test parameter with the parameter current of network;

Step 204: test cell 30 sends a test packets self-virtualizing network port 50, arrives IPMI 300 via virtual transmission passage 400 backs, then, is back to virtual network port 50 again;

Step 205: test cell 30 with the return information at virtual network port 50 places with send information and make comparisons, to obtain test result;

Step 206: test cell 30 judges whether this test result is unusual; If normal, enter step 208; If unusual, enter step 207;

Step 207: the unit 40 that the reports an error prompting that reports an error;

Step 208: parameter set unit 31 is reduced into the preceding parameter of test with the parameters of network.
