Embodiment
The embodiment of the invention provides a kind of detection method, device and access device of port failure, can the unmatched fault of port working mode of Ethernet access device and opposite equip. generation be detected automatically, pinpoints the problems fast.For making purpose of the present invention, technical scheme and advantage clearer, the embodiment that develops simultaneously with reference to the accompanying drawings, the present invention is described in more detail.
As shown in Figure 2, the detection method flow chart of the Ethernet access device port failure that provides for the embodiment of the invention one comprises following process:
If the working method of the described access device port of step 202 is half-duplex, read the error count of described access device port, calculate half-duplex mistake index increased numbers according to described error count;
If the described half-duplex mistake of step 203 index increased numbers surpasses default error thresholds, determine that the fault that do not match appears in the working method of described access device port.
Wherein, in the described step 202, the error count that reads described access device port specifically can comprise: send the Collisions increased numbers, send Late Collisions increased numbers, send the Aborts increased numbers and receive the Aborts increased numbers and reception CRC increased numbers.
Half-duplex mistake index increased numbers then can be calculated according to following formula:
(α sends Collisions increased numbers+β and sends Late Collisions increased numbers+γ transmission aborts increased numbers+δ reception Aborts increased numbers+μ reception CRC increased numbers)/1 second; Wherein: α, β, γ, δ, μ are weight coefficient, and α, β, γ, δ, μ are respectively more than or equal to 0; And have at least one not to be 0 among α, β, the γ.
From above-mentioned formula as can be seen, the formula that is used to calculate half-duplex mistake index increased numbers is not unique, and it can have a variety of, for example is respectively 1 as α, β, γ; δ, μ were respectively 0 o'clock, and above-mentioned formula is: send Collisions increased numbers+transmission Late Collisions increased numbers+transmission Aborts increased numbers)/1 second; Working as α for another example is 1; β and γ are 0; δ, μ were respectively 1,0 o'clock, and above-mentioned formula is: (sending Collisions increased numbers+reception Aborts increased numbers)/1 second; Other situation is similar with it, just repeats no more at this.
In the described step 203, if described wrong index increased numbers surpasses default error thresholds, the working method of determining described access device port occurs not matching in the step of fault, and described error thresholds can be set according to concrete actual conditions, for example is set at 15.
For fear of erroneous judgement, in actual applications,, determine that described access device port occur the not matching step of fault can be specially if described wrong index increased numbers surpasses default error thresholds:
When the continuous a plurality of monitoring periods of described wrong index increased numbers all surpass error thresholds, determine that the fault that do not match appears in the current working method of described access device port.Wherein, described error thresholds can be set according to concrete actual conditions, for example is set at 15.Described a plurality of monitoring period can be set according to concrete actual conditions, for example is set at 3.
In addition, in described step 203, if described wrong index increased numbers surpasses default error thresholds, determine that the current working method of described access device port occurs not matching after the fault, can also comprise the step that fault is automatically handled, wherein can to adopt the working method of port switching be full duplex in the automatic processing of fault; And/or transmission alarm; And/or log; And/or be achieved by sending in the mode such as EMAIL informing network keeper one or more.
In addition, can also comprise before the step of the register of the described port physical layer chip that reads access device:
Access device port auto-negotiation enables, and physical chip begins to consult after detecting carrier wave, and link couples together after consulting successfully, continues subsequent step; When can't consulting within the predetermined time when successful, determine that the working method that working method that described access device port is current and opposite equip. port are supported does not match.Preferably, send alarm when consulting within the predetermined time when successful, also comprise to adopt; And/or log; And/or by send EMAIL informing network keeper etc. automatically one or more in the handling failure mode be achieved.
Below, by a concrete application example the above embodiment of the present invention is described further.
Access device consults to be half-duplex mode that opposite equip. is operated in full duplex mode.Access device is before sending frame data, if opposite equip. is sending data, this moment access device can to detect channel occupied, then can wait for a period of time sends data again, thisly detects the situation that the occupied postponement of channel sends and can write down the Deferred mistake one time.
When access device and opposite equip. all send frame data simultaneously, access device is owing to be operated in half-duplex mode, the CSMA/CD algorithm can detect the carrier signal that opposite equip. sends, can think conflict has taken place, so stop the frame oneself to send, the Deferred error count also can increase once, resends data after waiting for a period of time.If preceding 64 bytes of access device transmit frame also do not have entry-line, can write down and once send the Collisions mistake, if preceding 64 bytes of transmit frame entry-line can write down and once send Late Collisions mistake.The frame that this moment, opposite equip. sended over can be dropped, and record once receives the Aborts mistake then.In this case, the frame that opposite equip. is received is incomplete, and CRC check can be made mistakes, and once receives crc error so can note down.
If same frame continuous 15 times the Deferred mistake takes place, then this frame will be dropped, and can write down and once send the Aborts mistake.
Access device is monitored at these mistakes and just can be detected the unmatched fault of this working method in conjunction with reading of working method, and does respective handling.Specifically as shown in Figure 3, unmatched detection of working method and processing procedure schematic diagram during the Ethernet access device half-duplex that provides for the embodiment of the invention two comprise following process:
Need to prove that in actual applications, above-mentioned steps 301 and step 302 are alternative.
Whether the wrong index increased numbers that step 305, judgement are calculated surpasses error thresholds, if do not surpass, then next cycle just continues to read.For example: error thresholds is 15, has then just surpassed this error thresholds 15 according to the increased numbers in the previous examples 20;
In addition, can also comprise that the working method of step 307, access device port switching physical layer is a full duplex, make two ends port type coupling.
Also have another kind of failure condition, access device is the port of 1000BASE-TX type, has enabled auto-negotiation, and opposite equip. is only supported 100MHALF and 10MHALF mode, has enabled auto-negotiation.
Also has another kind of failure condition, it is (the 1000BASE-TX port for example of ether access device when not supporting half-duplex operation, only support three kinds of working methods of 1000MFULL, 100MFULL and 10MFULL), and opposite equip. is only supported half-duplex operation, two ends have all enabled auto-negotiation, though two ends can receive the FLP of opposite end, two ends do not have the common working method of supporting, therefore link can't enter connection status, can't operate as normal.If the port working mode is not supported half-duplex, then can when the beginning auto-negotiation, just write down negotiation time, if can't consult success for a long time, for example above 5 seconds, think that then the opposite equip. port only supports half-duplex, cause the two ends port duplex to mate, at this moment can send alarm to the network manager, the informing network keeper carries out subsequent treatment.
