For clearly demonstrating the present invention, the present embodiment runs on as main first server 1 explanation of surveying end for described network port test system 41.Specifically to test the first network interface 11 explanation of described first server 1.In other embodiments, also can described second server 2 be main survey end be example explanation.
As previously described, when described network port test system 41 runs on the server as main survey end, this network port test system 41 performs described notification module 411, judge module 412, logging modle 413 and test module 414.
Step S1, notification module 411, when the first network interface 11 of described first server 1 gets IP address, sends a broadcast to broadcast the information of this first network interface 11 through this first network interface 11 in local area network (LAN).The information of this first network interface 11 comprises the MAC Address of the first network interface 11 and described IP address.
Step S2, judge module 412 judges whether have other servers to respond described broadcast in the scheduled time.If respond this broadcast without any server in the scheduled time, then perform step S3, logging modle 413 sets up relation correspondence table and the corresponding network interface recording described first network interface 11 in this relation correspondence table is this first network interface 11 itself.Such as consult shown in Fig. 4, the MAC Address supposing described first network interface 11 is 00-01-02-03-04-05, IP address is 10.11.12.13.Then described logging modle 413 records the MAC Address of the corresponding network interface of this first network interface 11 in this mapping table are 00-01-02-03-04-05, IP addresses is MAC Address and IP addresses that 10.11.12.13(that is to say this first network interface itself).Step S6 is performed after execution of step S3.
If there is certain station server to respond this broadcast in the scheduled time, now perform step S4.Such as, described second server 2 has responded this broadcast, now performs step S4.
Step S4, described logging modle 413 obtain responded described broadcast server (as described in second server 2) in, for responding the information of the network interface of described broadcast, the information of this network interface comprises MAC Address and the IP address of this network interface.
Such as, suppose that described second server 2 is through second network interface 21 to respond described broadcast, so described logging modle 413 obtains MAC Address and the IP address of this second network interface 21, the MAC Address such as getting this second network interface 21 is 00-01-02-03-04-07, IP address is 10.11.12.15.
And for example, suppose that described second server 2 is through the second network interface 22 to respond described broadcast, so described logging modle 413 obtains MAC Address and the IP address of this second network interface 22.
Step S5, the corresponding network interface that described logging modle 413 records described first network interface 11 in described relation correspondence table is the described network interface for responding broadcast.
Consult equally shown in Fig. 4, the MAC Address supposing described first network interface 11 is 00-01-02-03-04-06, IP address is 10.11.12.14, if described second server 2 is through described second network interface 21 to respond described broadcast, then described logging modle 413 is after the MAC Address getting described second network interface 21 and IP address, the MAC Address recording the corresponding network interface of this first network interface 11 in described relation correspondence table is 00-01-02-03-04-07, IP address is 10.11.12.15.
It should be noted that, if when having multiple servers such as to also have the 3rd station server also to do response to this broadcast in local area network (LAN), described logging modle 413 will can respond the network interface of the server of described broadcast as corresponding network interface at first in the described scheduled time.
Step S6, described judge module 412 judges whether other network interfaces (such as described first network interface 12) of described first server 1 also have corresponding network interface in described mapping table.If each network interface of this first server 1 all has corresponding network interface in described mapping table, now perform step S7, otherwise get back to step S1, when these other network interfaces get IP address, in local area network (LAN), broadcast MAC Address and the IP address of these other network interfaces.
Step S7, test module 414 is tested according to the corresponding relation set up in described mapping table each network interface (such as the first network interface 11,12) to described first server 1.
Particularly, the corresponding network interface supposing to record in described mapping table described first network interface 11 is described second network interface 21, owing to can know MAC Address and the IP address of this second network interface 21 from this mapping table, therefore, described test module 414 can send a default packet through this first network interface 11 to described second network interface 21, described first network interface 11 is determined whether can receive according to described first network interface 11 this packet returned by described second network interface 21, second network interface 21, and for connecting port (the such as described port 31 of this first network interface 11 and the second network interface 21 in described switch 3, 33) whether function is normal.
Here it should be noted that, due to described test module 414 send described packet through the first network interface 11 to described second network interface 21 time, described packets need flows through in described switch 3 for connecting the port 31 of described first network interface 11 and the port 33 for being connected described second port 21, equally, when this packet is returned to described first network interface 11 by described second network interface 21, this packet also will flow through the port 31 of described switch 3, 33, therefore, if when described first network interface 11 receives the described packet passed back by this second network interface 21, described test module 414 can determine described first network interface 11, second network interface 21, and for connecting port (the i.e. described port 31 of this first network interface 11 and the second network interface 21 in described switch 3, 33) function is normal.
And for example, suppose to record the corresponding network interface of described first network interface 11 in described mapping table for this first network interface 11 itself, described test module 414 sends described packet through this first network interface 11 to this first network interface 11 itself, to determine in described first network interface 11 and described switch 3 for the function of the port (such as port 31) connecting this first network interface 11 whether be normal whether can receive the described packet passed back by described switch 3 according to described first network interface 11.
It should be noted that equally, due to described test module 414 send described packet through the first network interface 11 to this first network interface 11 itself time, described packets need flows through in described switch 3 for connecting the port 31 of described first network interface 11, when described switch 3 receives this packet through this port 31, confirm that this packet will hand to this first network interface 11, then this packet can be transferred back to this first network interface 11 by described switch 3.Therefore, if when described first network interface 11 receives the described packet passed back by described switch 3, it is normal that described test module 414 can be determined in described first network interface 11 and described switch 3 for the function of the port (i.e. port 31) connecting this first network interface 11.
As shown in Figure 5, be the second flow chart of network interface method of testing of the present invention preferred embodiment.
