技术领域 Technical field
本发明涉及通信技术领域， 尤其涉及一种端口故障的检测方法、装置及接 入设备和***。  The present invention relates to the field of communications technologies, and in particular, to a port fault detection method and apparatus, and an access device and system.
背景技术 Background technique
现在大部份以太网接入设备都是 100BASE-TX或者 1000BASE-TX类型的 端口， 默认使能自协商（即可以与其他网络设备协商确定最合适的工作方式和 速率）， 通过五类双铰线接入用户家庭网关 （HG, Home Gateway )或者计算 机， 如图 1所示。 其中， 100BASE-TX是通过两对五类非屏蔽双绞线或者屏蔽 双绞线进行传输的 100Mbps载波侦听多路访问 /冲突检测 （CSMA/CD, Carrier Sense Multiple Access/Collision Detected )局域网的 IEEE 802.3物理层规格； 1000BASE-TX是通过四对五类平衡铜质电缆进行传输的 1000Mbps CSMA/CD 局域网的 IEEE 802.3物理层规格。 由于对端设备的用户可能会错误修改网卡或 者 HG的端口模式， 所以经常会发生端口模式不匹配的问题。  Most Ethernet access devices are now 100BASE-TX or 1000BASE-TX ports. By default, auto-negotiation is enabled (that is, it can negotiate with other network devices to determine the most suitable working mode and rate). The line accesses the user home gateway (HG, Home Gateway) or the computer, as shown in Figure 1. Among them, 100BASE-TX is a 100Mbps carrier sense multiple access/collision detection (CSMA/CD, Carrier Sense Multiple Access/Collision Detected) LAN transmission through two pairs of five types of unshielded twisted pair or shielded twisted pair. 802.3 Physical Layer Specification; 1000BASE-TX is the IEEE 802.3 physical layer specification for 1000Mbps CSMA/CD LANs transmitted over four to five balanced copper cables. Since the user of the peer device may incorrectly modify the port mode of the network card or HG, the port mode mismatch problem often occurs.
在实现本发明的过程中，发明人经过研究发现现有技术中以太端口模式不 匹配可能会导致用户无法正常使用业务， 例如， 接入设备使能了自协商模式， 而对端设备端口工作在强制 100MFULL ( 100兆全双工） 方式下， 协商时接入 设备发出快速连接脉冲 （FLP, Fast Link Pulse ), 对端设备只发送 IDLE信号， 这样接入设备根据码型可以知道对端设备的传输速度是 100M, 但是不知道对 端设备端口工作的双工方式， 虽然链路可以进入连接状态， 而接入设备端口最 终会工作的 100MHALF ( 100兆半双工） 方式， 和对端设备工作的 100MFULL 方式是不匹配的， 此时就会大量丟失报文。  In the process of implementing the present invention, the inventors have found through research that the Ethernet port mode mismatch in the prior art may cause the user to be unable to use the service normally. For example, the access device enables the auto-negotiation mode, and the peer device port works in the In the forced 100MFULL mode, the access device sends a fast link pulse (FLP, Fast Link Pulse) during negotiation, and the peer device only sends the IDLE signal, so that the access device can know the peer device according to the pattern. The transmission speed is 100M, but the duplex mode of the peer device port is not known, although the link can enter the connection state, and the access device port will eventually work in the 100MHALF (100 mega-duplex) mode, and the peer device works. The 100MFULL mode is mismatched, and a large number of messages are lost.

( α发送 Collisions增长数 + β发送 Late Collisions增长数 + γ发送 aborts 增长数 + δ接收 Aborts增长数 + μ接收 CRC增长数） /1秒； 其中： α、 β、 γ、 δ、 μ为权重系数， α、 β、 γ、 δ、 μ分别大于等于 0; 且 α、 β、 γ中至少有一个 不为 0。  (α sends Collisions growth number + β sends Late Collisions growth number + γ sends aborts growth number + δ receives Aborts growth number + μ receives CRC growth number) /1 second; where: α, β, γ, δ, μ are weight coefficients , α, β, γ, δ, μ are respectively greater than or equal to 0; and at least one of α, β, γ is not 0.
从上述公式可以看出， 用于计算半双工错误指标增长数的公式并不唯一， 可以有^^多种， 例如， 当 α、 β、 γ分别为 1 ; δ、 μ分别为 0时， 上述公式即为： 发送 Collisions增长数 +发送 Late Collisions增长数 +发送 Aborts增长数） /1 秒； 再如， 当 α为 1 ; β和 γ均为 0; δ、 μ分别为 1、 0时， 上述公式即为： （发 送 Collisions增长数 +接收 Aborts增长数 ) /1秒； 其他的情况与之类似， 在此 就不再赘述。 It can be seen from the above formula that the formula used to calculate the growth index of the half-duplex error index is not unique, and there may be multiple types, for example, when α, β, and γ are respectively 1; δ and μ are 0 respectively. The above formula is: send Collisions growth number + send Late Collisions growth number + send Aborts growth number) / 1 second; for example, when α is 1; β and γ are 0; δ, μ are 1, 0, respectively The above formula is: Send Collisions growth number + receive Aborts growth number) / 1 second; other situations are similar, and will not be repeated here.
所述的步骤 203 , 即如果所述错误指标增长数超过预设的错误门限， 即可 确定所述接入设备端口的工作方式出现不匹配故障的步骤中，所述的错误门限 可以依照具体实际情况而设定， 例如设定为 15。  Step 203, that is, if the error indicator growth number exceeds a preset error threshold, it may be determined that the operation mode of the access device port fails to match, and the error threshold may be determined according to a specific actual situation. Set it for the case, for example, set to 15.
此外， 为了避免误判， 在实际应用中， 如果所述错误指标增长数超过预设 的错误门限， 即可确定所述接入设备端口出现不匹配故障的步骤可以具体为： 当所述错误指标增长数连续多个监控周期都超过错误门限时 ,即可确定所 述接入设备端口当前的工作方式出现不匹配故障。 其中， 所述的错误门限可以 依照具体实际情况而设定， 例如设定为 15。 所述多个监控周期可以依照具体 实际情况而设定， 例如设定为 3。 即当所述半双工错误指标增长数超过所述预 设的错误门限（如 15 )的连续监控周期数超过预设值（如 3 )时， 即可确定所 述接入设备端口当前的工作方式出现不匹配故障。 例如连续 4 个监控周期内 (超过了预设值 3 ), 计算出的半双工错误指标增长数均超过预设的错误门限 值， 则确定该接入设备端口当前的工作方式出现了不匹配故障。  In addition, in order to avoid misjudgment, in an actual application, if the error indicator growth number exceeds a preset error threshold, the step of determining that the access device port has a mismatch failure may be specifically: When the number of consecutive monitoring periods exceeds the error threshold, it is determined that the current working mode of the access device port is mismatched. The error threshold may be set according to a specific situation, for example, set to 15. The plurality of monitoring periods may be set according to a specific situation, for example, set to 3. That is, when the number of consecutive monitoring periods in which the half-duplex error indicator increase exceeds the preset error threshold (eg, 15) exceeds a preset value (eg, 3), the current work of the access device port may be determined. There is a mismatch in the way. For example, if the calculated half-duplex error indicator growth exceeds the preset error threshold within 4 consecutive monitoring periods (beyond the preset value of 3), it is determined that the current working mode of the access device port does not appear. Match the fault.
此外， 在所述的步骤 203 , 即如果所述错误指标增长数超过预设的错误门 限，确定所述接入设备端口当前的工作方式出现不匹配故障后，还可以包括故 障自动处理的步骤，其中所述的故障自动处理可以通过切换端口的工作方式为 全双工； 和 /或发送告警； 和 /或记录日志； 和 /或通过发送 EMAIL通知网络管 理员等方式中的一种或几种予以实现。  In addition, in step 203, that is, if the error indicator growth number exceeds a preset error threshold, and after determining that the current working mode of the access device port has a mismatch failure, the step of automatically processing the fault may also be included. The fault automatic processing may be performed by switching the working mode of the port to full duplex; and/or sending an alarm; and/or recording a log; and/or notifying the network administrator by sending an EMAIL or the like. Realized.
另外，所述读取接入设备的端口物理层芯片的寄存器的步骤之前还可以包 括：  In addition, the step of reading the register of the physical layer chip of the port of the access device may further include:
接入设备端口自协商使能， 物理层芯片检测到载波后开始协商， 当协商成 功后链路连接起来， 继续后续步骤； 当在预定的时间内无法协商成功时， 确定 所述接入设备端口当前的工作方式与对端设备端口所支持的工作方式不匹配。 优选的， 当在预定的时间内无法协商成功时， 还包括通过发送告警； 和 /或记 录日志；和 /或通过发送 EMAIL通知网络管理员等自动处理故障方式中的一种 或几种予以实现。  After the auto-negotiation of the access device is enabled, the physical layer chip starts to negotiate after detecting the carrier. After the negotiation succeeds, the link is connected, and the subsequent steps are continued. When the negotiation fails successfully within the predetermined time, the access device port is determined. The current working mode does not match the working mode supported by the peer device port. Preferably, when the negotiation cannot be successful within a predetermined time, the method further includes: sending an alarm; and/or recording a log; and/or by sending an EMAIL to notify the network administrator or the like to automatically handle one or more of the failure modes. .
下面， 通过一个具体的应用实例对本发明上述实施例作进一步说明。 接入设备协商为半双工方式，对端设备工作在全双工方式。接入设备在发 送一帧数据前，如果对端设备正在发送数据， 此时接入设备会检测到信道被占 用， 则会等待一段时间再发送数据， 这种检测到信道被占用推迟发送的情况会Hereinafter, the above embodiment of the present invention will be further described by a specific application example. The access device negotiates in half-duplex mode and the peer device works in full-duplex mode. Before the access device sends a frame of data, if the peer device is transmitting data, the access device will detect that the channel is occupied, and then wait for a period of time before sending data. This detects that the channel is occupied and delayed transmission. meeting
■i己录一次 Deferred错误。 ■i has recorded a Deferred error.
当接入设备和对端设备同时都发送一帧数据时，接入设备由于工作在半双 工方式， CSMA/CD算法会检测到对端设备发出的载波信号， 会认为发生了冲 突， 于是停止自己发送的帧， Deferred错误计数也会增加一次， 等待一段时间 后重新发送数据。 如果接入设备发送帧的前 64字节还没有进入线路， 会记录 一次发送 Collisions错误，如果发送帧的前 64字节已经进入线路，会记录一次 发送 Late Collisions错误。 此时对端设备发送过来的帧数据会被丟弃， 然后记 录一次接收 Aborts错误。 这种情况下， 对端设备接收到的帧数据是不完整的， CRC校验会出错， 所以会纪录一次接收 CRC错误。  When both the access device and the peer device send one frame of data at the same time, the access device operates in the half-duplex mode, and the CSMA/CD algorithm detects the carrier signal sent by the peer device, and considers that a collision has occurred. The frame sent by itself, the Deferred error count will also be incremented once, and the data will be resent after waiting for a while. If the first 64 bytes of the frame sent by the access device have not entered the line, a Collisions error will be logged. If the first 64 bytes of the transmitted frame have entered the line, a Late Collisions error will be logged. At this time, the frame data sent by the peer device will be discarded, and then the Aborts error will be recorded once. In this case, the frame data received by the peer device is incomplete, and the CRC check will be in error, so a CRC error will be recorded.
如果同一个帧数据连续 15次发生 Deferred错误，则该帧数据将会被丟弃， 会记录一次发送 Aborts错误。  If a Deferred error occurs for the same frame data 15 times in a row, the frame data will be discarded and an Aborts error will be logged.
接入设备针对上述错误进行监控并结合工作方式的读取就可以检测出该 种工作方式不匹配的故障， 并做出相应的处理。 具体如图 3所示， 其为本发明 实施例二提供的以太网接入设备半双工时工作方式不匹配的检测和处理过程 示意图， 包括如下过程：  The access device monitors the above errors and combines the reading of the working mode to detect the fault that does not match the working mode, and performs corresponding processing. Specifically, as shown in FIG. 3, it is a schematic diagram of a process for detecting and processing a half-duplex working mode mismatch of an Ethernet access device provided by Embodiment 2 of the present invention, including the following process:
步骤 301、 接入设备端口为 100BASE-TX, 自协商使能， 物理层芯片检测 到载波后开始协商， 协商成功后链路连接起来；  Step 301: The access device port is 100BASE-TX, and the auto-negotiation is enabled. After the physical layer chip detects the carrier, the negotiation starts. After the negotiation succeeds, the link is connected.
步骤 302、 还有一种情况也会开始影响端口物理层的工作方式， 就是网络 管理员手工修改接入设备端口的模式， 例如修改端口工作方式为 100MHALF, 并不使能自协商， 这种情况就会直接修改端口物理层芯片的工作方式；  Step 302: Another situation will also affect the working mode of the physical layer of the port. That is, the network administrator manually modifies the mode of the access device port. For example, if the working mode of the port is 100MHALF, auto-negotiation is not enabled. Will directly modify the working mode of the port physical layer chip;
需要说明的是， 在实际应用中， 上述步骤 301和步骤 302为二选一。  It should be noted that, in practical applications, the foregoing steps 301 and 302 are two-choice.
步骤 303、读取物理层芯片的寄存器，判断当前的工作方式是否是半双工 , 如果是， 则继续后续步骤； 否则结束此流程；  Step 303: Read a register of the physical layer chip, determine whether the current working mode is half duplex, and if yes, continue the subsequent steps; otherwise, end the process;
步骤 304、 如果是半双工， 就定时读取端口的错误计数， 计算半双工错误 指标增长数， 例如： 错误指标增长数通过公式： （发送 Collisions增长数 +发送 Late Collisions增长数 +发送 Aborts增长数） /1秒进行计算，假设某一秒种内， 发送 Collisions增长数为 10, 发送 Late Collisions增长数为 5 , 发送 Aborts增 长数为 5, 则错误指标增长数即为 20; Step 304: If it is half-duplex, periodically read the error count of the port, and calculate the half-duplex error indicator growth number, for example: the error indicator growth number is expressed by the formula: (send Collisions growth number + send Late Collisions growth number + send Aborts Growth number) / 1 second to calculate, assuming a certain number of seconds, Send Collisions growth number to 10, send Late Collisions growth number to 5, send Aborts growth number to 5, then the error indicator growth number is 20;
步骤 305、 判断计算出来的错误指标增长数是否超过错误门限， 如果没有 超过， 则下一个周期就继续读取。 例如： 错误门限为 15, 则按照前面例子中 的增长数 20就超过了该错误门限 15;  Step 305: Determine whether the calculated error indicator growth exceeds the error threshold. If not, the next cycle continues to be read. For example: if the error threshold is 15, then the error threshold is exceeded by 20 according to the growth number 20 in the previous example;
步骤 306、 为了避免误判， 还可以在整个流程中增加此步骤， 即在错误指 标增长数多次超过错误门限后才认为出现了端口不匹配故障， 例如： 连续 3 个周期。 检测到该种故障后， 接入设备需要向外界通知该故障， 则可以釆用发 送告警、 记录日志等方法向外界通知该故障。  Step 306. In order to avoid misjudgment, the step may be added in the whole process, that is, the port mismatch fault is considered to occur after the error indicator grows more than the error threshold multiple times, for example: 3 consecutive periods. After the fault is detected, the access device needs to notify the outside world of the fault. Then, the fault can be notified to the outside world by sending an alarm or logging.
此外， 上述流程还可以包括：  In addition, the above process may further include:
步骤 307、 接入设备切换端口物理层的工作方式为全双工， 使两端端口类 型匹配。  Step 307: The working mode of the physical layer of the access device switching port is full duplex, so that the port types at both ends match.
还有另一种故障情况， 即接入设备是 1000BASE-TX类型的端口， 使能了 自协商， 而对端设备只支持 100MHALF和 10MHALF方式， 使能了自协商。  There is another fault condition, that is, the access device is a 1000BASE-TX type port, and auto-negotiation is enabled. The peer device only supports 100MHALF and 10MHALF modes, and auto-negotiation is enabled.
还有另一种故障情况， 即以太接入设备不支持半双工工作方式时 （例如 1000BASE-TX端口， 只支持 1000MFULL、 100MFULL和 10MFULL三种工 作方式）， 而对端设备只支持半双工工作方式， 两端都使能了自协商， 虽然两 端都可以接收到对端的 FLP, 但是两端没有共同支持的工作方式， 因此链路无 法进入连接状态， 无法正常工作。 如果端口工作方式不支持半双工， 则可以在 开始自协商时就记录协商时间， 如果长时间无法协商成功， 例如超过 5秒， 则 认为对端设备端口只支持半双工， 导致两端设备端口的双工方式无法匹配， 这 时可以向网络管理员发送告警 , 通知网络管理员进行后续处理。  There is another fault condition, that is, when the Ethernet access device does not support the half-duplex working mode (for example, 1000BASE-TX port, only 1000MFULL, 100MFULL, and 10MFULL are supported), and the peer device only supports half-duplex. In the working mode, auto-negotiation is enabled on both ends. Although both ends can receive the FLP of the peer end, there is no working mode supported by the two ends. Therefore, the link cannot enter the connection state and cannot work normally. If the working mode of the port does not support half-duplex, you can record the negotiation time at the beginning of the auto-negotiation. If the negotiation fails for a long period of time, for example, the peer device port supports only half-duplex. The duplex mode of the port cannot be matched. In this case, you can send an alarm to the network administrator to notify the network administrator for subsequent processing.
