## Background
BACKGROUND
1. Field of Invention
The present invention relates to a Wake On LAN (WOL) test system and method thereof. More particularly, the present invention relates to a Wake On LAN (WOL) test system and method thereof under a Client/Server structure with an ILO remote management service platform.
2. Description of Related Art
When testing the Wake On LAN (WOL) function of the network card, the QA engineer must make repeated round trips between the waking end and the woken end. First, the waking end must has a DHCP server function computer connected to a switch hub with WOL software installed, such as AMD Power Magic Utility. The MAC ID of the network card on the woken end can be obtained from the ROM-Based Setup Utility (RBSU) or the Operation System (OS). And the woken end must connect to the network domain of the waking end. During the WOL test, the QA engineer must apply the hibernate function or power shutdown on the woken end, and go to the waking end to implement the WOL software, and then manually key in the MAC ID of the woken end to send the WOL Magic Packet via the WOL software. The QA engineer then has to go back to the woken end to check if the computer has woken up. As the above-mentioned procedure, that is a single test for one network card. Though for testing all the network cards of the woken end, it is necessary to repeat the above-mentioned procedure until every network card has been test.
The WOL test options includes: the WOL test in hibernation under Windows OS, the WOL test after system shutdown under Windows OS, the WOL test in switch button-triggered hibernation under Windows OS, the WOL test after switch button shutdown under Windows OS, the WOL test after switch button shutdown under Unix & Unix-Like Operation System, etc.
The present WOL test using the above-mentioned procedure to test a single network card for only one test option, and to repeat the same procedure to test another network card, until all the network cards have been tested. During the test procedures and operations, the manpower and the procedures of accessing the MAC IDs, keying in the MAC IDs from the waking end and sending WOL Magic Packets are time-consuming. And the omissions and mistakes of manpower testing are hard to prevent.
SUMMARY
For this reason, this invention provides a Wake On LAN (WOL) test system and method thereof, applying in such as the Windows operation system, the Unix operation system and the Linux operation system with the Client/Server structure of an examiner end and an examinee end. The WOL test system sends the MAC ID of all the network cards of the examinee end by the WOL module. The WOL module retrieves the MAC ID of the examinee end from the MAC ID list to enclose in a WOL Magic Packet, and sends the magic packet to the examinee end to wake on LAN.
The invention relates to the ILO management platform. By the communication under the ILO remote management platform, the power condition of the examining target is acknowledged accurately. That is, when sending out the “Shutdown” or “Hibernate” command, it is possible to query the condition of the examinee end computer and whether the command is executed correctly via the ILO management platform. Thus, after sending out the WOL Magic Packet in the test system of the invention, it is possible to acknowledge that the examinee end computer has woken up. But if the WOL Magic Packet fails to send, the system will re-send the WOL Magic Packet again automatically. The reacting time of the system is as short as a man-made test, but it reduces the key-in time of manpower. Nevertheless, when the WOL Magic Packet fails to send multiple times, the system will send out “Power On” packet direct to the examinee end computer via the ILO management platform to start up the examinee end computer and continue the next test stage, instead of canceling the test.
The test configuration set via the WOL test module user interface of the invention, it simplifies the above-mentioned complicated procedure of “Shutdown” or “Hibernate” command as the condition variables through the Application Program Interface (API), or the System Message Post or the Event Post to the examinee end computer. And, the test method of WOL of the invention examines all the network cards in sequence, according to the automatically set condition variables such as shutdown or hibernate, MAC ID retrieving, the magic packet sending, Wake On LAN, and continuing test toward the next network card. Thus the invention improves the primitive WOL test procedure only operated through manpower, and reduces the testing manpower and time. Furthermore, the WOL test module user interface of the invention provides displaying instantaneous test progresses and test results in HTML format. It is able to highlight test results in different colors as HTML files, for instance, displaying failing results in red as well as displaying successful results in blue, to simplify the querying.
Therefore, the Wake On LAN (WOL) test system of the invention takes the place of using humans to do the testing, reduces time used, and prevents omissions caused by human error thereby improving the entire efficiency of WOL test. The testing time of applying the test system and method of the invention is around 30 ̃50 minutes and less. Comparing to the sum of the testing time of the traditional test operation around 1 ̃1.5 hours, the efficiency is increased by about 40% ̃50%.
It is to be understood that both the foregoing general description and the following detailed description are by examples, and are intended to provide further explanation of the invention as claimed.

After Step 452, the procedure goes to Step 460. In Step 460, if the WOL tests of all the examinee ends 200 ̃20n are not finished, the procedure returns to Step 420 to continue the WOL test toward the next examinee end 200; or ends the procedure if all the WOL tests are finished.
Wherein Step 400 further comprises a detailed procedure A illustrated in FIG. 2B. Refer to FIG. 2B, the detailed procedure A comprises steps as follows. Applying the WOL module 2001 on the examinee end 200 (Step 401). Retrieving a MAC ID of the examinee end 200 by the WOL module 2001 (Step 402). Connecting to the examiner end 100 by the WOL module 2001 and sending the MAC ID back to the examiner end 100 (Step 403). After Step 403, the examiner end 100 gathers all the MAC IDs of network card 2002-20n2 of the examinee end 200 ̃20n, and the procedure goes to Step 410.
