Step 201: the MAC Address tracked for needs, is key assignments in the b-tree data knot pre-established using MAC Address
It is traversed in structure.
When inquiry, only it need to be found out in the binary tree data structure pre-established using MAC Address as major key and need to track
Situation of the MAC Address in all VLAN, and the result found is still saved with binary tree structure.Here, it is contemplated that
The same MAC Address possibly is present in different virtual LAN (VLAN, Virtual Local Area Network), because
This, needs to save the switching port on all MAC Address and its corresponding exchange chip found out.It should be noted that such as
The result that fruit finds out only one, then, it is only necessary to saved using simple data structure, such as ordinary construction figure
Variable etc..
When by this step using MAC Address as major key binary tree traversal, VLAN corresponding with the MAC Address has been found out

Between mapping table, it is generally the case that the mapping table can be Hash (Hash) data structure；
After finding corresponding terminal device such as ONU equipment, further positions the corresponding user of the MAC Address and flank
Mouthful, as shown in fig. 1.And in ONU equipment, it equally will record the corresponding relationship of MAC Address and user side interface, it is only necessary to
The primary mapping table is traversed, the corresponding user side interface of the MAC Address can be found.
So far, the process of MAC Address tracking is just completed, a complete MAC address learning link has also defined.
It is first by way of being respectively processed according to the corresponding port type of each MAC Address found out in the present invention
First the corresponding device type of the MAC Address traversed out is screened, to carry out faulty equipment in a smaller range
Searching, improve the tracking efficiency that faulty equipment is corresponded to the MAC Address.
It should be noted that the function of exchange chip in every first device is responsible for hardware study in learning process, looking into
It can be handled from being read in system software in hardware chip when inquiry.In pon, general study link be PC machine ->
Passageway exchange board -> ONU terminal -> PON board -> master control board card.More complicated study link is also had in special networking,
Such as in CHINA RFTCOM Co Ltd, set-top box and television set etc. will also include.For winning ONU terminal level-one, the lower report for hanging PC machine
Text is transmitted to ONU terminal by passageway exchange board, and when which reaches ONU terminal for the first time, the exchange chip of ONU terminal can be incited somebody to action
Source MAC and its corresponding VLAN and port numbers in the message are recorded in the mac address table of exchange chip；In this way, working as
When tracking this level-one, system software will be read out one by one MAC Address from exchange chip.
Step 203: according to obtained study link, determining the MAC Address, corresponding there are the physical bits of the equipment of failure
Confidence breath.
According to study link of the MAC Address respectively found analyzed one by one in step 202 in different VLAN
According to obtained study link, the faulty equipment in network is automatically determined, is specifically included:
Still by taking PON as an example, at maintenance scene, in corresponding step 201~step 202, maintenance personnel can be by OLT
On, after determining that the MAC Address of faulty equipment, operation maintenance personnel input the MAC Address using the function of such as loop detection etc, equipment
Will automatic tracing faulty equipment MAC Address, and the study link tracing result of faulty equipment is finally fed back into O&M people
Member.In this way, after completing tracking, in step 203, the corresponding user-side port of the MAC Address for needing to track or network-side port
Also just apparent: if it is confirmed that being that there are failures for the corresponding equipment of this MAC Address, installation record can be directly inquired,
Determine the physical location of faulty equipment, and then to searching corresponding user under corresponding port.
