一种用于定位端口连接错误的方法和相关设备A method and related equipment for locating port connection errors

技术领域technical field

本发明涉及通信领域，尤其涉及一种用于定位端口连接错误的方法和相关设备。The invention relates to the communication field, in particular to a method for locating port connection errors and related equipment.

背景技术Background technique

对于现网的一些网络设备，在进行光纤连接施工时可能会出现端口的物理连接发生错误的情况。端口的物理连接发生错误的情况可以是出现鸳鸯线。如图1所示，A设备包括端口1、端口2和端口3，B设备包括端口1＇、端口2＇和端口3＇。正确的端口连接情况是端口1的TX与端口1＇的RX连接。端口1的RX与端口1＇的TX连接。但是如果出现端口2的RX与端口3＇的TX连接，端口3的RX与端口2＇的TX连接的情况，就出现了鸳鸯线。鸳鸯线的存在可能导致通信出现故障。进而导致业务流量无法转发。For some network devices on the existing network, errors in the physical connection of the ports may occur during the construction of optical fiber connections. An error in the physical connection of the port can be a mandarin duck line. As shown in FIG. 1, the A device includes port 1, port 2 and port 3, and the B device includes port 1', port 2' and port 3'. The correct port connection is that the TX of port 1 is connected with the RX of port 1'. RX of port 1 is connected to TX of port 1'. However, if the RX of port 2 is connected to the TX of port 3', and the RX of port 3 is connected to the TX of port 2', a mandarin duck line will appear. The presence of mandarin duck lines may cause communication failures. As a result, service traffic cannot be forwarded.

链路层发现协议(LinkLayerDiscoveryProtocol，LLDP)提供了一种标准的链路层发现方式。第一设备和第二设备的每个端口独立维护本地系统管理信息库(managementinformationbase，MIB)和远端系统MIB。第一设备每个端口可以周期性地将第一设备的主要能力、管理地址、设备标识、端口标识等信息组织成不同的类型/长度/值(Type/Length/Value，TLV)，并封装在LLDP报文中。第一设备的端口可以将LLDP报文发送至与第一设备的端口直连的第二设备的端口。第二设备是第一设备的邻居设备。第二设备会对收到的LLDP报文及其携带的TLV进行有效性检查，并将接收到的第一设备的本地系统MIB保存为第二设备的端口的远端系统MIB。一旦邻居第二设备的端口的LLDP本地系统MIB或LLDP远端系统MIB发生变化，该邻居第二设备的端口就会发送LLDP告警，指示该第二设备的端口的物理连接出现问题。Link Layer Discovery Protocol (LinkLayerDiscoveryProtocol, LLDP) provides a standard link layer discovery method. Each port of the first device and the second device independently maintains a local system management information base (management information base, MIB) and a remote system MIB. Each port of the first device can periodically organize information such as the main capabilities of the first device, management addresses, device identifiers, and port identifiers into different types/lengths/values (Type/Length/Value, TLV), and encapsulate them in in LLDP packets. The port of the first device may send the LLDP packet to the port of the second device directly connected to the port of the first device. The second device is a neighbor device of the first device. The second device will check the validity of the received LLDP message and the TLV carried by it, and save the received local system MIB of the first device as the remote system MIB of the port of the second device. Once the LLDP local system MIB or LLDP remote system MIB of the port of the neighboring second device changes, the port of the neighboring second device will send an LLDP alarm, indicating that there is a problem with the physical connection of the port of the second device.

上述通过LLDP协议确定端口的物理连接是否出现问题的方法，在某些场景中不能够高效地定位端口的物理连接是否发生错误。譬如，进行光纤连接施工时出现了鸳鸯线，网络设备的端口的TX能够发送光信号，并且端口的RX能够接收光信号，端口物理连接发送错误的问题不能被发现。因此，不能及时定位端口的物理连接是否发生错误。The above-mentioned method of determining whether there is a problem with the physical connection of the port through the LLDP protocol cannot efficiently locate whether an error occurs in the physical connection of the port in some scenarios. For example, when a mandarin duck line appears during the construction of optical fiber connection, the TX of the port of the network equipment can send optical signals, and the RX of the port can receive optical signals, and the problem of sending errors in the physical connection of the ports cannot be found. Therefore, whether an error occurs in the physical connection of the port cannot be located in time.

Figure 1 shows the situation of mandarin duck line. The RX of port 2 is connected to the TX of port 3', and the RX of port 3 is connected to the TX of port 2'.

实施例一Embodiment one

本发明实施例提供一种用于定位端口连接错误的方法，参见图2，其步骤包括：An embodiment of the present invention provides a method for locating port connection errors, referring to Figure 2, the steps include:

101、第一设备的第一端口向第二设备的第二端口发送第一端口的本地系统管理信息库MIB。101. The first port of the first device sends the local system management information base MIB of the first port to the second port of the second device.

举例来说，在链路层发现协议LLDP中，每个设备的每个端口均有一个本地系统MIB和远端系统MIB，并且每个端口独立维护自己的本地系统MIB和远端系统MIB。其中，“管理信息”就是指在因特网的网管框架中被管对象的集合。被管对象必须维持可供管理程序读写的若干控制和状态信息。这些被管对象构成了一个虚拟的信息存储器，所以才称为管理信息库MIB。MIB是一个数据库，它代表了某个设备或服务的一套可管理对象。For example, in the link layer discovery protocol LLDP, each port of each device has a local system MIB and a remote system MIB, and each port independently maintains its own local system MIB and remote system MIB. Wherein, "management information" refers to a collection of managed objects in the network management framework of the Internet. A managed object must maintain certain control and state information that can be read and written by the hypervisor. These managed objects constitute a virtual information storage, so it is called the management information base MIB. MIB is a database that represents a set of manageable objects for a certain device or service.

举例来说，对于一个端口来说，其本地系统MIB存储的是端口的本地MIB，为待发送给对端设备的端口的信息，远端MIB存储的是与该端口连接的对端设备的端口的MIB，也即远端MIB存储的是从对端设备的端口接收到的信息。MIB可以包括设备ID，端口ID、系统名称、系统描述、端口描述、设备能力和网络管理地址等。For example, for a port, its local system MIB stores the local MIB of the port, which is the port information to be sent to the peer device, and the remote MIB stores the port of the peer device connected to the port The MIB, that is, the remote MIB stores the information received from the port of the peer device. MIB can include device ID, port ID, system name, system description, port description, device capability and network management address, etc.

具体的，应用LLDP，第一设备的第一端口向第二设备的第二端口发送第一端口的本地系统MIB的实现方式可以为：第一设备的第一端口向第二设备的第二端口发送第一LLDP报文，该第一LLDP报文携带第一端口的本地系统MIB。Specifically, by applying LLDP, the first port of the first device sends the local system MIB of the first port to the second port of the second device in the following manner: the first port of the first device sends the second port of the second device Send a first LLDP packet, where the first LLDP packet carries the local system MIB of the first port.

102、第一设备的第三端口接收第二设备的第二端口发送的第一端口的本地系统MIB。102. The third port of the first device receives the local system MIB of the first port sent by the second port of the second device.

当第二设备的第二端口接收到第一设备的第一端口发送的第一LLDP报文以后，第二设备建立远端MIB，即第二设备将第一LLDP报文携带的第一端口的本地系统MIB保存为第二端口的远端系统MIB，以存储第一设备的第一端口发送过来的第一端口的本地系统MIB。After the second port of the second device receives the first LLDP message sent by the first port of the first device, the second device establishes a remote MIB, that is, the second device carries the first LLDP message of the first port The local system MIB is saved as the remote system MIB of the second port to store the local system MIB of the first port sent from the first port of the first device.

而后，第二设备的第二端口通过第二LLDP报文向第一设备返回第一端口的本地系统MIB，同时，第二LLDP报文携带标识信息，该标识信息用于标识第二设备发送的第一端口的本地系统MIB是第二设备的端口的远端系统MIB。Then, the second port of the second device returns the local system MIB of the first port to the first device through the second LLDP message, and at the same time, the second LLDP message carries identification information, and the identification information is used to identify the MIB sent by the second device. The local system MIB of the first port is the remote system MIB of the port of the second device.

具体来说，所述第二设备的端口可以是所述第二端口。Specifically, the port of the second device may be the second port.

举例来说，该第二LLDP报文可以包括第一TLV和第二TLV，标识信息包括第一TLV中的类型字段的值以及第二TLV中的类型字段的值，第一TLV中的类型字段的值指示第一TLV中的信息串字段携带的是设备的标识，第二TLV中的类型字段的值指示第二TLV中的信息串字段携带的是端口的标识，第二设备的端口的远端系统MIB包括第一设备的标识以及第一端口的标识，第一TLV中的类型字段的值用于标识第二设备发送的第一设备的标识是第二设备的端口的远端系统MIB中的第一设备的标识(ChassisID)，第二TLV中的类型字段的值用于标识第二设备发送的第一端口的标识是第二设备的端口的远端系统MIB中的第一端口的标识(PortID)。For example, the second LLDP packet may include a first TLV and a second TLV, the identification information includes the value of the type field in the first TLV and the value of the type field in the second TLV, and the type field in the first TLV The value indicates that the information string field in the first TLV carries the identifier of the device, the value of the type field in the second TLV indicates that the information string field in the second TLV carries the identifier of the port, and the remote port of the second device The end system MIB includes the identifier of the first device and the identifier of the first port, and the value of the type field in the first TLV is used to identify that the identifier of the first device sent by the second device is in the remote system MIB of the port of the second device The identifier (ChassisID) of the first device, the value of the type field in the second TLV is used to identify the identifier of the first port sent by the second device is the identifier of the first port in the remote system MIB of the port of the second device (PortID).

具体来说，所述第一TLV中的信息串字段携带的设备的标识可以是所述第一设备的标识。所述第二TLV中的信息串字段携带的端口的标识可以是所述第一端口的标识。Specifically, the device identifier carried in the information string field in the first TLV may be the first device identifier. The port identifier carried in the information string field in the second TLV may be the identifier of the first port.

这是由于，在现有的LLDP报文中，定义了9种TLV，TLV类型字段的值使用了0-8，用以表示发送端发送的本地系统MIB，这样，可以通过扩展两种TLV，其TLV类型字段的值可以为9和10，TLV类型字段的值为9表示发送端发送的是端口的远端系统MIB中的设备标识，TLV类型字段的值为10表示发送端发送的是端口的远端系统MIB中的端口标识。这样，第一设备的第三端口就可以根据该标识信息识别出接收到的MIB来自于对端设备也即第二设备的端口的远端系统MIB。这里的TLV类型字段的值为9的TLV可以携带的是第一设备的标识，TLV类型字段的值为10的TLV可以携带的是第一端口的标识。This is because, in the existing LLDP message, 9 kinds of TLV are defined, and the value of the TLV type field uses 0-8 to indicate the local system MIB sent by the sender. In this way, by extending the two TLVs, The value of the TLV type field can be 9 or 10. The value of the TLV type field is 9, indicating that the sender sends the device identifier in the remote system MIB of the port, and the value of the TLV type field is 10, indicating that the sender sends the port The port ID in the remote system MIB. In this way, the third port of the first device can recognize, according to the identification information, that the received MIB comes from the peer device, that is, the remote system MIB of the port of the second device. Here, the TLV with the value of 9 in the TLV type field may carry the identifier of the first device, and the TLV with the value of 10 in the TLV type field may carry the identifier of the first port.

103、第一设备确定第三端口的本地系统MIB与第二设备发送的第一端口的本地系统MIB不同。103. The first device determines that the local system MIB of the third port is different from the local system MIB of the first port sent by the second device.

如果第一设备的第三端口接收到第二设备发送的第一端口的本地系统MIB以及标识信息，根据该标识信息获知该第一端口的本地系统MIB来自于第二设备的端口的远端系统MIB，于是，第一设备就基于该标识信息的指示比较第三端口的本地系统MIB与第二设备发送的第一端口的本地系统MIB，根据比较结果确定第三端口的本地系统MIB与第一端口的本地系统MIB是否相同。If the third port of the first device receives the local system MIB and the identification information of the first port sent by the second device, it is learned from the identification information that the local system MIB of the first port comes from the remote system of the port of the second device MIB, then, based on the indication of the identification information, the first device compares the local system MIB of the third port with the local system MIB of the first port sent by the second device, and determines the difference between the local system MIB of the third port and the first port according to the comparison result. Whether the local system MIBs of the ports are the same.

举例来说，这里的第一端口的本地系统MIB可以包括第一设备的标识和第一端口的标识，第三端口的本地系统MIB可以包括第一设备的标识和第三端口的标识。也就是说，在比较时可以将设备的标识和端口的标识进行比对，以确认是否相同。For example, the local system MIB of the first port may include the identifier of the first device and the identifier of the first port, and the local system MIB of the third port may include the identifier of the first device and the identifier of the third port. That is to say, during comparison, the identification of the device and the identification of the port can be compared to confirm whether they are the same.

104、第一设备基于第三端口的本地系统MIB与第一端口的本地MIB系统不同确定第一端口与第二设备的物理连接发生错误或者第三端口与第二设备的物理连接发生错误。104. The first device determines that an error occurs in the physical connection between the first port and the second device or that an error occurs in the physical connection between the third port and the second device based on the difference between the local system MIB of the third port and the local MIB system of the first port.

当第一设备的第一端口向第二设备的第二端口发送了第一端口的本地系统MIB时，说明第一设备的第一端口的TX与第二设备的第二端口的RX连接，按照设备的物理连接无误的情况，第一设备的第一端口的RX需要连接第二设备的第二端口的TX，也就是说，应该是第二设备的第二端口将从第一设备接收到的第一端口的本地系统MIB回传至第一设备的第一端口，而如果第二设备的第二端口的TX物理连接错误至了第一设备的第三端口的RX，当第三端口接收到第二设备回传的第一端口的本地系统MIB时，第三端口将第三端口的本地系统与接收到的第一端口的本地系统MIB进行比较发现不同，第三端口就确认第一端口与第二设备的物理连接发生错误，或者是第三端口与第二设备的物理连接发生错误。When the first port of the first device sends the local system MIB of the first port to the second port of the second device, it means that the TX of the first port of the first device is connected with the RX of the second port of the second device, according to If the physical connection of the device is correct, the RX of the first port of the first device needs to be connected to the TX of the second port of the second device, that is, it should be the second port of the second device that will receive from the first device The local system MIB of the first port is returned to the first port of the first device, and if the TX physical connection of the second port of the second device is incorrectly connected to the RX of the third port of the first device, when the third port receives When the second device returns the local system MIB of the first port, the third port compares the local system of the third port with the received local system MIB of the first port and finds that they are different, and the third port confirms that the An error occurs in the physical connection of the second device, or an error occurs in the physical connection between the third port and the second device.

其中，物理连接发生错误是指设备的某一端口与对端设备的某一端口的TX或RX连接错误。Wherein, a physical connection error refers to a TX or RX connection error between a certain port of the device and a certain port of the peer device.

在第一设备确认第一端口或第三端口的物理连接发生错误的情况下，第一设备可以向管理设备发送错误告警，该错误告警携带第一端口的标识或第三端口的标识，错误告警中的第一端口的标识用于标识第一端口与第二设备的物理连接发生错误，错误告警中的第三端口的标识用于标识第三端口与第二设备的物理连接发生错误。When the first device confirms that an error occurs in the physical connection of the first port or the third port, the first device may send an error alarm to the management device, the error alarm carries the identity of the first port or the identity of the third port, and the error alarm The identifier of the first port in the error alarm is used to identify an error in the physical connection between the first port and the second device, and the identifier of the third port in the error alarm is used to identify an error in the physical connection between the third port and the second device.

由于每个设备的每个端口都是独立的接收、发送信息的，所以每个发生物理连接错误的端口可以独立地发送一个错误告警，这样，出现鸳鸯线这种物理连接错误所涉及到的四个端口，均可以独立发送一个错误告警。Since each port of each device receives and sends information independently, each port where a physical connection error occurs can independently send an error alarm. Each port can independently send an error alarm.

本发明实施例提供一种用于定位端口连接错误的方法，第一设备的第一端口向第二设备的第二端口发送第一端口的本地系统MIB，第一设备的第三端口接收第二设备的第二端口发送的第一端口的本地系统MIB，而后当第一设备确定第三端口的本地系统MIB与第二设备发送的第一端口的本地系统MIB不同时，第一设备确定第一端口与第二设备的物理连接发生错误或者第三端口与第二设备的物理连接发生错误，这样通过将第一端口的本地系统MIB回传至第一设备的方式，有助于高效定位端口的物理连接发生错误。An embodiment of the present invention provides a method for locating port connection errors. The first port of the first device sends the local system MIB of the first port to the second port of the second device, and the third port of the first device receives the second The local system MIB of the first port sent by the second port of the device, and then when the first device determines that the local system MIB of the third port is different from the local system MIB of the first port sent by the second device, the first device determines that the first port The physical connection between the port and the second device is incorrect, or the physical connection between the third port and the second device is incorrect. In this way, the local system MIB of the first port is sent back to the first device, which helps to locate the port efficiently. An error occurred in the physical connection.

实施例二Embodiment two

以实施例一中第一设备的对端设备第二设备为执行主体，本发明实施例提供另一种用于定位端口连接错误的方法。参见图3，其步骤包括：Taking the second device as the peer device of the first device in Embodiment 1 as the execution subject, this embodiment of the present invention provides another method for locating port connection errors. Referring to Figure 3, the steps include:

201、第二设备的第二端口接收第一设备的第一端口发送的第一端口的本地系统MIB。201. The second port of the second device receives the local system MIB of the first port sent by the first port of the first device.

第二设备的第二端口在接收到第一端口的本地系统MIB后，可以将第一端口的本地系统MIB保存为第二端口的远端系统MIB。After receiving the local system MIB of the first port, the second port of the second device may save the local system MIB of the first port as the remote system MIB of the second port.

202、第二设备的第二端口向第一设备的第三端口发送第一端口的本地系统MIB。202. The second port of the second device sends the local system MIB of the first port to the third port of the first device.

第二设备在将接收到的第一端口的本地系统MIB保存为第二端口的远端系统MIB后，可以依据远端系统MIB中保存的第一端口的本地系统MIB向第一设备的第三端口发送第一端口的本地系统MIB，使得第一设备的第三端口在接收到第一端口的本地系统MIB后，可以基于第三端口的本地系统MIB与第一端口的本地系统MIB不同确定第一端口与第二设备的物理连接发生错误或者第三端口与第二设备的物理连接发生错误。After the second device saves the received local system MIB of the first port as the remote system MIB of the second port, it can send the data to the third port of the first device according to the local system MIB of the first port saved in the remote system MIB The port sends the local system MIB of the first port, so that after receiving the local system MIB of the first port, the third port of the first device can determine the second port based on the difference between the local system MIB of the third port and the local system MIB of the first port. An error occurs in the physical connection between a port and the second device or an error occurs in the physical connection between the third port and the second device.

其中，在第二设备的第二端口向第一设备的第三端口发送第一端口的本地系统MIB的同时，第二设备的第二端口向第一设备的第三端口发送标识信息，标识信息用于标识第二设备发送的第一端口的本地系统MIB是第二设备的端口的远端系统MIB。所述第二设备的端口具体可以是所述第二端口。这样可以指示第三端口根据接收到第一端口的本地系统MIB与第三端口的本地系统MIB进行比较，以确认是否相同来确认第三端口或第一端口是否发生物理连接错误。Wherein, when the second port of the second device sends the local system MIB of the first port to the third port of the first device, the second port of the second device sends identification information to the third port of the first device, and the identification information The local system MIB used to identify the first port sent by the second device is the remote system MIB of the port of the second device. The port of the second device may specifically be the second port. In this way, the third port may be instructed to compare the received local system MIB of the first port with the local system MIB of the third port to confirm whether they are the same to determine whether a physical connection error occurs on the third port or the first port.

本实施例中第一设备和第二设备的具体实现方式可以参见实施例一中的说明过程，这里不再赘述。For the specific implementation manners of the first device and the second device in this embodiment, reference may be made to the description process in Embodiment 1, which will not be repeated here.

本发明实施例提供一种用于定位端口连接错误的方法，第二设备的第二端口接收第一设备的第一端口发送的第一端口的本地系统MIB，然后第二设备的第二端口向第一设备的第三端口发送第一端口的本地系统MIB，使得第一设备基于第三端口的本地系统MIB与第一端口的本地系统MIB不同确定第一端口与第二设备的物理连接发生错误或者第三端口与第二设备的物理连接发生错误，这样通过将第一端口的本地系统MIB回传至第一设备的方式，有助于高效定位端口的物理连接发生错误。An embodiment of the present invention provides a method for locating port connection errors. The second port of the second device receives the local system MIB of the first port sent by the first port of the first device, and then the second port of the second device sends The third port of the first device sends the local system MIB of the first port, so that the first device determines that an error occurs in the physical connection between the first port and the second device based on the difference between the local system MIB of the third port and the local system MIB of the first port. Or an error occurs in the physical connection between the third port and the second device. In this way, the local system MIB of the first port is returned to the first device, which helps to efficiently locate the error in the physical connection of the port.

实施例三Embodiment Three

本发明实施例提供一种用于定位端口连接错误的方法，参见图1所示的鸳鸯线错误连接，以实施例一和实施例二中的第一设备为图1中的A设备，第二设备为图1中的B设备进行说明，第一端口以A设备的端口2为例，第三端口以A设备的端口3为例，第二端口以B设备的端口2＇为例进行说明，参见图4，其步骤包括：The embodiment of the present invention provides a method for locating port connection errors. Refer to the error connection of the mandarin duck line shown in Figure 1. The first device in Embodiment 1 and Embodiment 2 is the A device in The device is the B device in Figure 1. The first port takes port 2 of the A device as an example, the third port takes the port 3 of the A device as an example, and the second port takes the port 2' of the B device as an example. Referring to Figure 4, the steps include:

301、A设备的端口2通过第一LLDP报文向B设备的端口2＇发送A设备的端口2的本地系统MIB。301. Port 2 of device A sends the local system MIB of port 2 of device A to port 2' of device B through the first LLDP packet.

其中，第一LLDP报文格式可以如下表1所示：Wherein, the format of the first LLDP packet may be as shown in Table 1 below:

表1Table 1

其中，链路层发现协议数据单元(LinkLayerDiscoveryProtocolDataUnit，LLDPDU)目前定义了9种TLV来携带端口发送的本地系统MIB，其TLV类型字段的值使用了0-8。而在发送一个LLDP报文时，一个LLDP报文中至少包含以下4种：ChassisIDTLV、PortIDTLV、TimetoliveTLV和EndofLLDPDUTLV。Among them, the Link Layer Discovery Protocol Data Unit (LinkLayerDiscoveryProtocolDataUnit, LLDPDU) currently defines 9 kinds of TLVs to carry the local system MIB sent by the port, and the value of the TLV type field uses 0-8. When sending an LLDP message, an LLDP message contains at least the following four types: ChassisIDTLV, PortIDTLV, TimetoliveTLV and EndofLLDPDUTLV.

其中，TimetoliveTLV的类型字段的值为3，用来设置远端MIB库的老化时间。例如，光纤物理连接无误的情况下，A设备的端口2周期性的通过组播报文将本地系统MIB发送给B设备的端口2＇，B设备的端口2＇将收到的A设备的端口2发送的本地系统MIB存入B设备的端口2＇的远端系统MIB，如果B设备的端口2＇超过预定的老化时间没有收到A设备的端口2发来的端口2的本地系统MIB，则B设备的端口2＇就清除掉上一次存入远端系统MIB中端口2的本地系统MIB。Wherein, the value of the type field of TimetoliveTLV is 3, which is used to set the aging time of the remote MIB library. For example, if the physical fiber connection is correct, port 2 of device A periodically sends the local system MIB to port 2' of device B through multicast packets, and port 2' of device B will receive the MIB of port 2 of device A. 2 The local system MIB sent is stored in the remote system MIB of port 2' of device B. If port 2' of device B exceeds the predetermined aging time and does not receive the local system MIB of port 2 sent by port 2 of device A, Then the port 2' of the B device clears the local system MIB stored in the port 2 of the remote system MIB last time.

EndofLLDPDUTLV的类型字段的值为0，用来表示一个LLDPDU的结束。LLDPDU数据块中有多个TLV，最后一个TLV的类型字段的值为0，代表该TLV为EndofLLDPDUTLV，表示一个LLDPDU的结束。The value of the type field of EndofLLDPDUTLV is 0, which is used to indicate the end of an LLDPDU. There are multiple TLVs in the LLDPDU data block, and the value of the type field of the last TLV is 0, indicating that the TLV is EndofLLDPDUTLV, indicating the end of an LLDPDU.

ChassisIDTLV，该TLV类型字段的值是1，表示该TLV的信息串字段携带的是设备标识。ChassisIDTLV的格式可以如下表2所示：ChassisIDTLV, the value of the TLV type field is 1, indicating that the information string field of this TLV carries the device identifier. The format of the ChassisIDTLV can be shown in Table 2 below:

表2Table 2

目前，TLV中的类型字段的值是1表示LLDP报文携带的是设备的端口的本地系统MIB中的设备的标识，也可以称为框架标识。其中，ChassisIDsubtype，一般为4，表示设备的标识是通过媒体访问控制(MediumAccessControl，MAC)地址来标识的。因此，表2中的ChassisID就可以为MAC地址。Currently, the value of the type field in the TLV is 1, indicating that the LLDP packet carries the device identifier in the local system MIB of the port of the device, which may also be called a frame identifier. Wherein, the ChassisIDsubtype is generally 4, indicating that the identifier of the device is identified by a Medium Access Control (MAC) address. Therefore, the ChassisID in Table 2 can be a MAC address.

PortIDTLV，TLV类型字段的值可以为2，表示该TLV携带的是端口标识，该TLV的格式可以如下表3所示：PortIDTLV, the value of the TLV type field can be 2, indicating that the TLV carries a port identifier, and the format of the TLV can be shown in Table 3 below:

表3table 3

其中，TLV类型字段的值是2表示LLDP报文的TLV信息串字段携带的是端口的本地系统MIB中的端口的标识。PortIDsubtype，一般为5，表示端口的标识通过端口的名称来识别的。Wherein, the value of the TLV type field is 2, indicating that the TLV information string field of the LLDP message carries the port identifier in the local system MIB of the port. PortIDsubtype, generally 5, indicates that the identification of the port is identified by the name of the port.

302、B设备的端口2＇在收到A设备的端口2的本地系统MIB后，将A设备的端口2的本地系统MIB保存到端口2＇的远端系统MIB。302. After receiving the local system MIB of port 2 of device A, port 2' of device B saves the local system MIB of port 2 of device A to the remote system MIB of port 2'.

在图1中，A设备的端口2的TX连接的是B设备的端口2＇的RX，所以A设备发送的第一LLDP报文由B设备的端口2＇接收到，B设备的端口2＇就将接收到的A设备的端口2的本地系统MIB添加到端口2＇的远端系统MIB。In Figure 1, TX on port 2 of device A is connected to RX on port 2' of device B, so the first LLDP packet sent by device A is received by port 2' of device B, and port 2' of device B Add the received local system MIB of port 2 of A device to the remote system MIB of port 2'.

303、B设备的端口2＇通过第二LLDP报文向A设备发送端口2的本地系统MIB。303. Port 2' of device B sends the local system MIB of port 2 to device A through the second LLDP packet.

B设备的端口2＇在保存了从A设备接收到的端口2的本地系统MIB后，B设备从B设备的端口2＇的远端系统MIB中再获取A设备的端口2的本地系统MIB，并发送至A设备。其中，B设备获取的A设备的端口2的本地系统MIB可以包括A设备的端口2的设备的标识和端口的标识。After port 2' of device B saves the local system MIB of port 2 received from device A, device B obtains the local system MIB of port 2 of device A from the remote system MIB of port 2' of device B. And send to A device. Wherein, the local system MIB of the port 2 of the A device acquired by the B device may include the device identifier and the port identifier of the port 2 of the A device.

B设备在发送A设备的端口2的本地系统MIB的同时，为了标识出是从B设备的端口2＇的远端系统MIB中获取的，需要同时发送一标识信息。具体方式为：第二LLDP报文中包括第一TLV和第二TLV，第一TLV和第二TLV为扩展后的TLV，第一TLV可以为扩展的ChassisIDTLV，第二TLV可以为扩展的PortIDTLV，标识信息可以包括扩展的ChassisIDTLV中的类型字段的值以及扩展的PortIDTLV中的类型字段的值，例如，扩展的ChassisIDTLV中的类型字段的值可以为9，扩展的PortIDTLV中的类型字段的值可以为10。While sending the local system MIB of port 2 of the A device, the B device needs to send identification information at the same time in order to identify that it is obtained from the remote system MIB of the port 2' of the B device. The specific method is: the second LLDP message includes the first TLV and the second TLV, the first TLV and the second TLV are extended TLVs, the first TLV may be an extended ChassisIDTLV, and the second TLV may be an extended PortIDTLV, The identification information may include the value of the Type field in the extended ChassisIDTLV and the value of the Type field in the extended PortIDTLV, for example, the value of the Type field in the extended ChassisIDTLV may be 9, and the value of the Type field in the extended PortIDTLV may be 10.

其中，扩展的ChassisIDTLV中的TLVtype＝9，可以指示该扩展的ChassisIDTLV中的信息串字段携带的是设备的标识，用于标识B设备发送的A设备的标识是B设备的端口的远端系统MIB中的A设备的标识，扩展的PortIDTLV中的TLVtype＝10，可以指示该扩展的PortIDTLV中的信息串字段携带的是端口的标识，用于标识B设备发送的端口2的标识是B设备的端口的远端系统MIB中的端口2的标识。Among them, TLVtype=9 in the extended ChassisIDTLV can indicate that the information string field in the extended ChassisIDTLV carries the identifier of the device, which is used to identify that the identifier of the A device sent by the B device is the remote system MIB of the port of the B device The identifier of the A device in the extended PortIDTLV, the TLVtype=10 in the extended PortIDTLV can indicate that the information string field in the extended PortIDTLV carries the identifier of the port, and is used to identify the identifier of the port 2 sent by the B device is the port of the B device The ID of port 2 in the remote system MIB.

这样一来，一个扩展的LLDP报文中至少包含以下4种：扩展的ChassisIDTLV、扩展的PortIDTLV、TimetoliveTLV和EndofLLDPDUTLV。其中TimetoliveTLV和EndofLLDPDUTLV和步骤301中的相同。In this way, an extended LLDP message contains at least the following four types: extended ChassisIDTLV, extended PortIDTLV, TimetoliveTLV and EndofLLDPDUTLV. The TimetoliveTLV and EndofLLDPDUTLV are the same as those in step 301.

扩展的ChassisIDTLV的格式和内容可以如下表4所示：The format and content of the extended ChassisIDTLV may be as shown in Table 4 below:

表4Table 4

扩展的PortIDTLV的格式和内容可以如下表5所示：The format and content of the extended PortIDTLV may be shown in Table 5 below:

表5table 5

304、A设备的端口3收到B设备的端口2＇发送的第二LLDP报文后，根据标识信息识别出第二LLDP报文携带的为B设备的端口的远端系统MIB。304. After receiving the second LLDP packet sent by port 2' of device B, port 3 of device A identifies the remote system MIB of the port of device B carried in the second LLDP packet according to the identification information.

由于B设备的端口2＇的TX错误连接到了A设备端口3的RX上，因此，B设备端口2＇向A设备返回第二LLDP报文时就发送到了A设备的端口3上。A设备的端口3根据第二LLDP报文中扩展的TLV，发现其中一TLV的类型值为9，得知该TLV携带的是B设备的端口的远端系统MIB中的ChassisID，并通过另一TLV的类型值为10，得知该TLV携带的是B设备的端口的远端系统MIB中的PortID，于是，A设备的端口3根据扩展后的TLV获知A设备接收到的第二LLDP报文是用来确认端口连接是否正确的，而不是B设备的端口的本地系统MIB，不需要对接收到的MIB信息进行存储。Since the TX of the port 2' of the B device is incorrectly connected to the RX of the port 3 of the A device, when the port 2' of the B device returns the second LLDP message to the A device, it is sent to the port 3 of the A device. According to the extended TLV in the second LLDP packet, port 3 of device A finds that the type value of one of the TLVs is 9, and learns that this TLV carries the ChassisID in the remote system MIB of the port of device B, and passes another The type value of the TLV is 10. It is known that the TLV carries the PortID in the remote system MIB of the port of the device B. Therefore, the port 3 of the device A obtains the second LLDP packet received by the device A according to the extended TLV. It is used to confirm whether the port connection is correct, not the local system MIB of the port of the B device, and does not need to store the received MIB information.

305、A设备端口3提取通过第二LLDP报文携带的远端系统MIB中A设备的端口2的本地系统MIB中的ChassisID和PortID，与端口3的本地系统MIB中的ChassisID和PortID进行比对，若两者不同，则端口3确定端口的物理连接发生错误，并向网络管理设备发送告警。305. Port 3 of device A extracts the ChassisID and PortID in the local system MIB of port 2 of device A in the remote system MIB carried by the second LLDP message, and compares it with the ChassisID and PortID in the local system MIB of port 3 , if the two are different, port 3 determines that an error occurs in the physical connection of the port, and sends an alarm to the network management device.

由于B设备返回的第二LLDP报文携带来自B设备的端口的远端系统MIB，该远端系统MIB包括A设备的端口2发给端口2＇的端口2的本地系统MIB。A设备的端口3根据标识信息识别出第二LLDP报文携带的为B设备的端口的远端系统MIB后，提取第二LLDP报文携带的端口的远端系统MIB中的ChassisID和PortID，该远端系统MIB中的ChassisID和PortID是A设备的端口2的本地系统MIB中的ChassisID和PortID，A设备的端口3通过将接收到的A设备的端口2的本地系统MIB中的ChassisID和PortID与端口3的本地系统MIB中的ChassisID和PortID进行比对，发现两者不同，这样，A设备的端口3就确认端口物理连接有误，向网络管理设备发送告警。Since the second LLDP packet returned by the B device carries the remote system MIB from the port of the B device, the remote system MIB includes the local system MIB sent from the port 2 of the A device to the port 2'. After port 3 of device A identifies the remote system MIB of the port of device B carried in the second LLDP packet according to the identification information, it extracts the ChassisID and PortID in the remote system MIB of the port carried in the second LLDP packet, and the The ChassisID and PortID in the remote system MIB are the ChassisID and PortID in the local system MIB of port 2 of device A, and port 3 of device A combines the received ChassisID and PortID in the local system MIB of port 2 of device A with The ChassisID and PortID in the local system MIB of port 3 are compared and found to be different. In this way, port 3 of device A confirms that the physical connection of the port is incorrect and sends an alarm to the network management device.

其中，该错误告警可以携带端口2的标识或端口3的标识，错误告警中的端口2的标识用于标识端口2与B设备的物理连接发生错误，错误告警中的端口3的标识用于标识端口3与B设备的物理连接发生错误。Wherein, the error alarm can carry the identification of port 2 or port 3, the identification of port 2 in the error alarm is used to identify the physical connection error between port 2 and B equipment, and the identification of port 3 in the error alarm is used to identify There is an error in the physical connection of port 3 to the B-device.

由于每个设备的每个端口都是独立的接收、发送信息的，所以每个物理连接错误的端口可以独立地上报一个告警，出现鸳鸯线连接错误所涉及到的四个端口，就可以独立上报告警。Since each port of each device receives and sends information independently, each port with a physical connection error can report an alarm independently, and the four ports involved in the connection error of the mandarin duck line can be reported independently. Report to the police.

这种通过本端接收到对端的本地系统MIB信息，本端将对端的本地系统MIB信息添加到本端的端口的远端系统MIB后，再将远端系统MIB通过扩展的TLV发送给对端，让对端确认端口连接是否错误的过程，可以及时准确地确定端口物理连接错误的位置。After the local end receives the local system MIB information of the peer end, the local end adds the local system MIB information of the peer end to the remote system MIB of the port of the local end, and then sends the remote system MIB to the peer end through the extended TLV. The process of allowing the peer to confirm whether the port connection is wrong can promptly and accurately determine the location of the wrong physical connection of the port.

本发明实施例提供一种用于定位端口连接错误的方法，A设备的端口2通过第一LLDP报文向B设备的端口2＇发送A设备的端口2的本地系统MIB，B设备的端口2＇将A设备的端口2的本地系统MIB保存到端口2＇的远端系统MIB，B设备的端口2＇通过第二LLDP报文向A设备发送端口2的本地系统MIB，A设备的端口3收到B设备的端口2＇发送的第二LLDP报文后，根据标识信息识别出第二LLDP报文携带的为B设备的端口的远端系统MIB，A设备端口3提取通过第二LLDP报文携带的远端系统MIB中A设备的端口2的本地系统MIB中的ChassisID和PortID，与端口3的本地系统MIB中的ChassisID和PortID进行比对，若两者不同，则端口3确定端口的物理连接发生错误，并向网络管理设备发送告警，有助于高效定位端口的物理连接发生错误。The embodiment of the present invention provides a method for locating port connection errors. Port 2 of A device sends the local system MIB of port 2 of A device to port 2' of B device through the first LLDP message, and port 2 of B device 'Save the local system MIB of port 2 of device A to the remote system MIB of port 2', port 2 of device B' sends the local system MIB of port 2 to device A through the second LLDP message, and port 3 of device A After receiving the second LLDP packet sent by port 2' of device B, it identifies the remote system MIB carried by the second LLDP packet as the port of device B according to the identification information, and port 3 of device A extracts the MIB of the port through the second LLDP packet. Compare the ChassisID and PortID in the local system MIB of port 2 of A device in the remote system MIB carried in the document with the ChassisID and PortID in the local system MIB of port 3. If the two are different, port 3 determines the port ID. An error occurs in the physical connection, and an alarm is sent to the network management device, which helps to efficiently locate the error in the physical connection of the port.
