Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to an interface configuration method and apparatus. Background Technology

[0002] A communication device may include physical interfaces, which can be configured in either Ethernet (Eth) mode or Flexible Ethernet (FlexE) mode. When two neighboring physical interfaces communicate, both interfaces can be configured in either Eth or FlexE mode. However, if one physical interface is configured in FlexE mode and the other in Eth mode, the two interfaces will not be able to communicate properly.

[0003] Currently, when two physical interfaces that are neighbors are configured, one in FlexE mode and the other in Eth mode, users, such as operations and maintenance personnel, need to manually configure one of the physical interfaces so that the two physical interfaces can communicate normally. However, this method is relatively inefficient. Summary of the Invention

[0004] This application provides an interface configuration method that can improve the configuration efficiency of physical interfaces.

[0005] Firstly, embodiments of this application provide an interface configuration method, which can be executed by a first communication device. The first communication device includes a first port, which can be used to communicate with a second port of a second communication device. In one example, the first communication device can determine the chip operating mode of the second port. When the chip operating mode of the second port is determined to be Eth mode, the first communication device can switch the chip operating mode of the first port from FlexE mode to Eth mode. In this way, the chip operating modes of the first port and the second port are both Eth mode, and therefore, the first port and the second port can communicate normally. Thus, using this solution, there is no need for the user to manually configure the chip operating mode of the first port; the first communication device can switch the chip operating mode of the first port according to the chip operating mode of the second port, improving the efficiency of configuring the first port.

[0006] In one implementation, considering that if FlexE communication is established between the first communication device and the second communication device, the first communication device can receive the FlexE overhead frame from the second communication device. Therefore, in one implementation, if the first communication device does not receive the FlexE overhead frame sent by the second communication device within a preset time, it indicates that FlexE communication has not been established between the first communication device and the second communication device. In this case, the first communication device can determine that the chip operating mode of the second port is Eth mode.

[0007] In one implementation, after the first communication device configures the chip operating mode of the first port to Eth mode, the first communication device can also receive first indication information sent by the second communication device. This first indication information instructs the first communication device to configure the chip operating mode of the first port to FlexE mode. Thus, in one example, the first communication device can configure the chip operating mode of the first port to FlexE mode, causing the first port to operate in FlexE mode. If the second port also operates in FlexE mode, FlexE communication can be established between the first and second communication devices.

[0008] In one implementation, the first indication information is a remote fault RF indication information. In one example, when the first communication device receives RF indication information from the second communication device, the first communication device can configure the chip operating mode of the first port to FlexE mode.

[0009] In one implementation, the first indication information includes the 00 code block of the first Ethernet frame sent by the second communication device. In one example, when the first communication device receives the first Ethernet frame from the second communication device, it can extract the value of the 00 code block of the first Ethernet frame, and when the value of the 00 code block of the first Ethernet frame is a preset value, such as 0x05, configure the chip operating mode of the first port to FlexE mode.

[0010] In one implementation, the first indication information may be carried in the extended TLV field of the first Ethernet frame sent by the second communication device. In one example, when the first communication device receives the first Ethernet frame from the second communication device, it can configure the chip operating mode of the first port to FlexE mode according to the extended TLV field in the first Ethernet frame.

[0011] In one implementation, the first communication device may further instruct the second communication device to configure the chip operating mode of the second port to FlexE mode. For example, in one example, the first communication device may instruct the second communication device to configure the chip operating mode of the second port to FlexE mode before configuring the chip operating mode of the first port to FlexE mode. Then, the first communication device configures the chip operating mode of the first port to FlexE mode. The second communication device may also configure the chip operating mode of the second port to FlexE mode based on the instruction from the first communication device. In this way, FlexE communication can be established between the first port and the second port.

[0012] In one implementation, the first communication device can instruct the second communication device to configure the chip operating mode of the second port to FlexE mode by periodically sending a second indication message to the second communication device within a predetermined time period. The second indication message is used to instruct the second communication device to configure the chip operating mode of the second port to FlexE mode. Periodically sending the second indication message to the second communication device within the predetermined time period ensures that the second communication device can receive the second indication message, thereby guaranteeing that the second communication device configures the chip operating mode of the second port to FlexE mode, and further enabling FlexE communication to be established between the first port and the second port.

[0013] In one implementation, the second indication information is a remote fault RF indication information. In one example, when the second communication device receives RF indication information from the first communication device, if the port configuration mode of the second port is FlexE mode and the chip operating mode of the second port is Eth mode, then the second communication device can configure the chip operating mode of the second port to FlexE mode.

[0014] In one implementation, the second indication information is the 00 code block of the fourth Ethernet frame sent by the first communication device. In one example, the value of the 00 code block of the fourth Ethernet frame sent by the first communication device to the second communication device can be 0x05.

[0015] In one implementation, the second indication information may be carried in the extended TLV field of the fourth Ethernet frame sent by the first communication device. In one example, when the second communication device receives the fourth Ethernet frame from the first communication device, it can configure the chip operating mode of the second port to FlexE mode according to the extended TLV field in the first Ethernet frame.

[0016] In one implementation, after the first communication device switches the chip operating mode of the first port from Eth mode to FlexE mode, it can also periodically detect the chip operating mode of the second port. If the chip operating mode of the second port differs from that of the first port, the chip operating mode of the first port is reconfigured to ensure consistency between the chip operating modes of the first and second ports. For example, in one instance, when the first communication device determines that the chip operating mode of the second port is Eth mode, it can switch the chip operating mode of the first port from FlexE mode to Eth mode.

[0017] In one implementation, after the first communication device switches the chip operating mode of the first port from FlexE mode to Eth mode, if the first communication device determines that the chip operating mode of the second port is FlexE mode, then the first communication device can switch the chip operating mode of the first port from Eth mode to FlexE mode.

[0018] In one implementation, when the chip operating mode of the first port is Eth mode, if the chip operating mode of the second port is also Eth mode, then the first port can receive a block lock signal from the second port. Therefore, if the first communication device does not receive a block lock signal sent by the second communication device within a preset time period, the first communication device can determine that the chip operating mode of the second port is FlexE mode.

[0019] In one implementation, when the chip operating mode of the first port is Eth mode, if the chip operating mode of the second port is also Eth mode, then the first port can receive an alignment marker lock signal from the second port. Therefore, if the first communication device does not receive the alignment marker lock signal sent by the second communication device within a preset time period, the first communication device can determine that the chip operating mode of the second port is FlexE mode.

[0020] In one implementation, the first communication device can determine the chip operating mode of the second port based on the value of the O0 code block sent by the second communication device. Specifically, when the value of the O0 code block sent by the second communication device is 0x05, the first communication device can determine that the chip operating mode of the second port is FlexE mode.

[0021] In one implementation, when the chip operating mode of the first port is Eth mode, the first communication device can determine the chip operating mode of the second port by sending a second Ethernet frame to the second communication device, wherein the second Ethernet frame is used to determine the chip operating mode of the second port. If the first communication device does not receive a response from the second communication device for the second Ethernet frame, the first communication device can determine that the chip operating mode of the second port is FlexE mode.

[0022] In one implementation, the second Ethernet frame includes an Extended Type Length Value (TLV) field, the extended TLV field including third indication information used to determine the chip operating mode of the second port.

[0023] In one implementation, the first port is configured in FlexE mode. This is because when the first port is configured in FlexE mode, it means that the first port can function as either an Eth interface or a FlexE interface. In other words, the chip operating mode of the first port can be configured in either FlexE mode or Eth mode. If the first port is configured in Eth mode, it may only be able to function as an Eth interface; in this case, the chip operating mode of the first port cannot be configured in FlexE mode.

[0024] Secondly, embodiments of this application provide an interface configuration method, which can be executed by a first communication device. The first communication device includes a first port, which can be used to communicate with a second port of a second communication device. In one example, the first communication device can receive first indication information sent by the second communication device, the first indication information being used to instruct the first communication device to configure the chip operating mode of the first port to FlexE mode. After receiving the first indication information, the first communication device can switch the chip operating mode of the first port from Eth mode to FlexE mode. Therefore, using this solution, there is no need for the user to manually configure the chip operating mode of the first port; the first communication device can configure the chip operating mode of the first port according to the first indication information sent by the second communication device, thus improving the efficiency of configuring the first port.

[0025] In one implementation, the first indication information is a remote fault RF indication information. In one example, when the first communication device receives RF indication information from the second communication device, the first communication device can configure the chip operating mode of the first port to FlexE mode.

[0026] In one implementation, the first indication information includes the 00 code block of the first Ethernet frame sent by the second communication device. In one example, when the first communication device receives the first Ethernet frame from the second communication device, it can extract the value of the 00 code block of the first Ethernet frame, and when the value of the 00 code block of the first Ethernet frame is a preset value, such as 0x05, configure the chip operating mode of the first port to FlexE mode.

[0027] In one implementation, the first indication information may be carried in the extended TLV field of the first Ethernet frame sent by the second communication device. In one example, when the first communication device receives the first Ethernet frame from the second communication device, it can configure the chip operating mode of the first port to FlexE mode according to the extended TLV field in the first Ethernet frame.

[0028] In one implementation, the first communication device may further instruct the second communication device to configure the chip operating mode of the second port to FlexE mode. For example, in one example, the first communication device may instruct the second communication device to configure the chip operating mode of the second port to FlexE mode before configuring the chip operating mode of the first port to FlexE mode. Then, the first communication device configures the chip operating mode of the first port to FlexE mode. The second communication device may also configure the chip operating mode of the second port to FlexE mode based on the instruction from the first communication device. In this way, FlexE communication can be established between the first port and the second port.

[0029] In one implementation, the first communication device can instruct the second communication device to configure the chip operating mode of the second port to FlexE mode by periodically sending a second indication message to the second communication device within a predetermined time period. The second indication message is used to instruct the second communication device to configure the chip operating mode of the second port to FlexE mode. Periodically sending the second indication message to the second communication device within the predetermined time period ensures that the second communication device can receive the second indication message, thereby guaranteeing that the second communication device configures the chip operating mode of the second port to FlexE mode, and further enabling FlexE communication to be established between the first port and the second port.

[0030] In one implementation, when the chip operating mode of the first port is FlexE mode, the first communication device can determine the chip operating mode of the second port. When the chip operating mode of the second port is determined to be Eth mode, the first communication device can switch the chip operating mode of the first port from FlexE mode to Eth mode. In this way, both the chip operating modes of the first and second ports are Eth mode, thus allowing normal communication between the first and second ports. Therefore, using this solution, there is no need for the user to manually configure the chip operating mode of the first port; the first communication device can switch the chip operating mode of the first port based on the chip operating mode of the second port, improving the efficiency of configuring the first port.

[0031] In one implementation, considering that if FlexE communication is established between the first communication device and the second communication device, the first communication device can receive the FlexE overhead frame from the second communication device. Therefore, in one implementation, if the first communication device does not receive the FlexE overhead frame sent by the second communication device within a preset time, it indicates that FlexE communication has not been established between the first communication device and the second communication device. In this case, the first communication device can determine that the chip operating mode of the second port is Eth mode.

[0032] In one implementation, after the first communication device switches the chip operating mode of the first port from Eth mode to FlexE mode, it can also periodically detect the chip operating mode of the second port. If the chip operating mode of the second port differs from that of the first port, the chip operating mode of the first port is reconfigured to ensure consistency between the chip operating modes of the first and second ports. For example, in one instance, when the first communication device determines that the chip operating mode of the second port is Eth mode, it can switch the chip operating mode of the first port from FlexE mode to Eth mode.

[0033] In one implementation, after the first communication device switches the chip operating mode of the first port from FlexE mode to Eth mode, if the first communication device determines that the chip operating mode of the second port is FlexE mode, then the first communication device can switch the chip operating mode of the first port from Eth mode to FlexE mode.

[0034] In one implementation, when the chip operating mode of the first port is Eth mode, if the chip operating mode of the second port is also Eth mode, then the first port can receive a block lock signal from the second port. Therefore, if the first communication device does not receive a block lock signal sent by the second communication device within a preset time period, the first communication device can determine that the chip operating mode of the second port is FlexE mode.

[0035] In one implementation, when the chip operating mode of the first port is Eth mode, if the chip operating mode of the second port is also Eth mode, then the first port can receive an alignment marker lock signal from the second port. Therefore, if the first communication device does not receive the alignment marker lock signal sent by the second communication device within a preset time period, the first communication device can determine that the chip operating mode of the second port is FlexE mode.

[0036] In one implementation, the first communication device can determine the chip operating mode of the second port based on the value of the O0 code block sent by the second communication device. Specifically, when the value of the O0 code block sent by the second communication device is 0x05, the first communication device can determine that the chip operating mode of the second port is FlexE mode.

[0037] In one implementation, when the chip operating mode of the first port is Eth mode, the first communication device can determine the chip operating mode of the second port by sending a second Ethernet frame to the second communication device, wherein the second Ethernet frame is used to determine the chip operating mode of the second port. If the first communication device does not receive a response from the second communication device for the second Ethernet frame, the first communication device can determine that the chip operating mode of the second port is FlexE mode.

[0038] In one implementation, the second Ethernet frame includes an Extended Type Length Value (TLV) field, the extended TLV field including third indication information used to determine the chip operating mode of the second port.

[0039] In one implementation, the first port is configured in FlexE mode. This is because when the first port is configured in FlexE mode, it means that the first port can function as either an Eth interface or a FlexE interface. In other words, the chip operating mode of the first port can be configured in either FlexE mode or Eth mode. If the first port is configured in Eth mode, it may only be able to function as an Eth interface; in this case, the chip operating mode of the first port cannot be configured in FlexE mode.

[0040] Thirdly, embodiments of this application provide an interface configuration method, which can be executed by a first communication device. The first communication device includes a first port, which can be used to communicate with a second port of a second communication device. In one example, the first communication device can determine the chip operating mode of the second port, and when the chip operating mode of the second port is different from the chip operating mode of the first port, adjust the chip operating mode of the first port to be the same as the chip operating mode of the second port. In other words, the first communication device can adjust the chip operating mode of the first port when the chip operating mode of the second port is different from the chip operating mode of the first port, so that the adjusted chip operating mode of the first port is the same as the chip operating mode of the second port, thereby enabling the first port and the second port to communicate normally. Therefore, using this solution, there is no need for the user to manually configure the chip operating mode of the first port; the first communication device can switch the chip operating mode of the first port according to the chip operating mode of the second port, improving the efficiency of configuring the first port.

[0041] In one implementation, when the chip operating mode of the first port is Eth mode and the chip operating mode of the second port is FlexE mode, the first communication device can adjust the chip operating mode of the first port from Eth mode to FlexE mode.

[0042] In one implementation, when the chip operating mode of the second port is Eth mode and the chip operating mode of the first port is FlexE mode, the first communication device can adjust the chip operating mode of the first port from FlexE mode to Eth mode.

[0043] In one implementation, considering that if FlexE communication is established between the first communication device and the second communication device, the first communication device can receive the FlexE overhead frame from the second communication device. Therefore, in one implementation, when the chip operating mode of the first port is FlexE mode, if the first communication device does not receive the FlexE overhead frame sent by the second communication device within a preset time, it indicates that FlexE communication has not been established between the first communication device and the second communication device. In this case, the first communication device can determine that the chip operating mode of the second port is Eth mode.

[0044] In one implementation, after the first communication device configures the chip operating mode of the first port to Eth mode, the first communication device can also receive first indication information sent by the second communication device. This first indication information instructs the first communication device to configure the chip operating mode of the first port to FlexE mode. Thus, in one example, the first communication device can configure the chip operating mode of the first port to FlexE mode according to the first indication information, thereby enabling the first port to operate in FlexE mode. If the second port also operates in FlexE mode, FlexE communication can be established between the first and second communication devices.

[0045] In one implementation, the first indication information is a remote fault (RF) indication information.

[0046] In one implementation, the first indication information includes an O0 code block in a first Ethernet frame sent by the second communication device.

[0047] In one implementation, receiving first indication information sent by the second communication device includes: receiving a first Ethernet frame sent by the second communication device, the first Ethernet frame including an Extended Type Length Value (TLV) field, the extended TLV field including the first indication information.

[0048] In one implementation, the first communication device may further instruct the second communication device to configure the chip operating mode of the second port to FlexE mode. For example, in one example, the first communication device may instruct the second communication device to configure the chip operating mode of the second port to FlexE mode before configuring the chip operating mode of the first port to FlexE mode. Then, the first communication device configures the chip operating mode of the first port to FlexE mode. The second communication device may also configure the chip operating mode of the second port to FlexE mode based on the instruction from the first communication device. In this way, FlexE communication can be established between the first port and the second port.

[0049] In one implementation, instructing the second communication device to configure the chip operating mode of the second port to FlexE mode includes: periodically sending a second indication message to the second communication device within a predetermined time period, the second indication message being used to instruct the second communication device to configure the chip operating mode of the second port to FlexE mode.

[0050] In one implementation, the first communication device can instruct the second communication device to configure the chip operating mode of the second port to FlexE mode by periodically sending a second indication message to the second communication device within a predetermined time period. The second indication message is used to instruct the second communication device to configure the chip operating mode of the second port to FlexE mode. Periodically sending the second indication message to the second communication device within the predetermined time period ensures that the second communication device can receive the second indication message, thereby guaranteeing that the second communication device configures the chip operating mode of the second port to FlexE mode, and further enabling FlexE communication to be established between the first port and the second port.

[0051] In one implementation, the second indication information is a remote fault RF indication information. In one example, when the second communication device receives RF indication information from the first communication device, if the port configuration mode of the second port is FlexE mode and the chip operating mode of the second port is Eth mode, then the second communication device can configure the chip operating mode of the second port to FlexE mode.

[0052] In one implementation, the second indication information is the 00 code block of the fourth Ethernet frame sent by the first communication device. In one example, the value of the 00 code block of the fourth Ethernet frame sent by the first communication device to the second communication device can be 0x05.

[0053] In one implementation, the second indication information may be carried in the extended TLV field of the fourth Ethernet frame sent by the first communication device. In one example, when the second communication device receives the fourth Ethernet frame from the first communication device, it can configure the chip operating mode of the second port to FlexE mode according to the extended TLV field in the first Ethernet frame.

[0054] In one implementation, when the chip operating mode of the first port is Eth mode, the first communication device can determine that the chip operating mode of the second port is FlexE mode if it does not detect the alignment marker lock signal sent by the second communication device within a preset time.

[0055] In one implementation, when the chip operating mode of the first port is Eth mode, the first communication device can determine that the chip operating mode of the second port is FlexE mode based on the value of the O0 code block sent by the second communication device. For example, when the value of the O0 code block sent by the second communication device is 0x05, the first communication device can determine that the chip operating mode of the second port is FlexE mode.

[0056] In one implementation, when the chip operating mode of the first port is Eth mode, the first communication device can determine the chip operating mode of the second port by sending a second Ethernet frame to the second communication device. The second Ethernet frame is used to determine the chip operating mode of the second port. In this case, if the first communication device does not receive a response from the second communication device for the second Ethernet frame, the first communication device can determine that the chip operating mode of the second port is FlexE mode.

[0057] In one implementation, the second Ethernet frame includes an Extended Type Length Value (TLV) field, the extended TLV field including third indication information used to determine the chip operating mode of the second port.

[0058] In one implementation, the first port is configured in FlexE mode. This is because when the first port is configured in FlexE mode, it means that the first port can function as either an Eth interface or a FlexE interface. In other words, the chip operating mode of the first port can be configured in either FlexE mode or Eth mode. If the first port is configured in Eth mode, it may only be able to function as an Eth interface; in this case, the chip operating mode of the first port cannot be configured in FlexE mode.

[0059] Fourthly, embodiments of this application provide an interface configuration method, which can be executed by a second communication device. The second communication device includes a second port for communicating with a first port of a first communication device. In one example, the second communication device can obtain first indication information, which instructs the first communication device to configure the chip operating mode of the first port to FlexE mode. After obtaining the first indication information, the second communication device can send it to the first communication device. Therefore, using this solution, the user does not need to manually configure the chip operating mode of the first port; instead, the second communication device sends the first indication information, instructing the first communication device to configure the chip operating mode of the first port to FlexE mode, thereby instructing the first communication device to configure the chip operating mode of the first port, improving the efficiency of configuring the first port.

[0060] In one implementation, after receiving a configuration instruction from the control and management entity, the second communication device can obtain the first indication information, wherein the configuration instruction instructs the second communication device to configure the second port to FlexE mode. In one example, the second communication device can configure both the port configuration mode and the chip operating mode of the second port to FlexE mode based on the configuration instruction. The first communication device can then configure the chip operating mode of the first port to FlexE mode based on the first indication information. In this way, FlexE communication can be established between the first and second communication devices.

[0094] This application provides an interface configuration method to improve the configuration efficiency of physical interfaces.

[0095] To make it easier to understand, we will first introduce the relevant content of Eth and FlexE.

[0096] For a given physical interface, it can be configured in either Eth mode or FlexE mode. For ease of description, in the following description of this application, a physical interface operating in FlexE mode will be referred to as a "FlexE interface," and a physical interface operating in Eth mode will be referred to as an "Eth interface." See also Figure 1a and Figure 1b , Figure 1a This is a schematic diagram of the structure of an Eth interface provided in an embodiment of this application. Figure 1b This is a schematic diagram of the structure of a FlexE interface provided in an embodiment of this application.

[0097] like Figure 1a As shown, the Eth interface includes a Media Access Control (MAC) layer, a Reconciliation Sublayer (RS), a Physical Coding Sublayer (PCS), a Physical Medium Attachment (PMA) sublayer, and a Physical Medium Dependent (PMD) sublayer. Figure 1b As shown, in addition to the MAC layer, RS, PCS, PMA sublayer and PMD sublayer, the FlexE interface has an additional FlexE shim layer between the MAC layer and PCS.

[0098] It should be noted that, Figure 1a and Figure 1b The structural differences between the Eth interface and the FlexE interface are illustrated merely for ease of understanding and do not constitute a limitation on the embodiments of this application. In some embodiments, the structure of the Eth interface and the FlexE interface is not limited to... Figure 1a and Figure 1b As shown.

[0099] For example, the Eth interface processes messages as follows: the PCS receives data and directly transmits it to the MAC layer, which then assembles the data into an Eth message.

[0100] For example, the FlexE interface has two message processing methods. The first method is: the PCS receives data and passes it to the FlexE shim, which then passes it to the MAC, and the MAC assembles the data into an Eth message. The second method is: the PCS of FlexE interface 1 receives data and sends it to the FlexE shim of FlexE interface 1, which then sends the data to the FlexE shim of FlexE interface 2, and the FlexE shim of FlexE interface 2 sends the data from its PCS to the link. FlexE interface 1 and FlexE interface 2 are neighbors and can communicate with each other. The FlexE interface can determine which of the two methods to use for message processing based on its configuration.

[0101] When two neighboring physical interfaces communicate, if one physical interface is configured in FlexE mode and the other in Eth mode, they will be unable to communicate properly. This is because the Eth interface processes packets from other devices, such as user equipment, differently than the FlexE interface. In one example:

[0102] When sending messages, the Eth interface, for a message from a user equipment, segments the message into 64-bit data, adds a 2-bit synchronization header before the data, forming a 66-bit information block, and then sends these 66-bit blocks sequentially onto the link. For example, if the Eth interface obtains four blocks after processing the message, it first sends block 1 onto the link, then block 2, and then blocks 3 and 4 in sequence. In this case, the data sent onto the link by the Eth interface is: block1|block2|block3|block4. Here, "A|B" indicates that two bit streams A and B are concatenated sequentially.

[0103] When the FlexE interface sends a message, the FlexE shim of that interface segments the message into 64-bit data, adds a 2-bit synchronization header to the beginning of the data, forming 66-bit blocks, and inserts these blocks into specific slots. For example, if the FlexE interface has four time slots, where time slots 1 and 3 are used to forward messages from user equipment 1, and time slots 2 and 3 are not yet allocated, then after processing the message from user equipment 1, the FlexE interface obtains two blocks, block 5 and block 6. The FlexE interface schedules block 5 to be forwarded on time slot 1, an empty block to be forwarded on time slot 2, block 6 to be forwarded on time slot 3, and an empty block to be forwarded on time slot 4. An empty block is one where all 66 bits of data are 0. In this case, the data sent to the link by the FlexE interface is: block 5 | empty block | block 6 | empty block.

[0104] Therefore, if the Eth interface and the FlexE interface interact, and the Eth interface sends a message to the FlexE interface, the FlexEshim cannot parse the correct data because the Eth interface sends data bit by bit, while FlexE receives data in specific time slots (according to user configuration). Consequently, when the FlexE interface sends a message to the Eth interface, the Eth interface also cannot parse the correct data.

[0105] As mentioned above Figure 1a and Figure 1b As described, if a physical interface supports being configured in FlexE mode, it can be configured in either Eth or FlexE mode. When the physical interface is configured in Eth mode, its FlexE shim does not process data. Whether the FlexE shim processes data can be determined by the chip's operating mode. In one example, when the chip's operating mode is configured in Eth mode, the FlexE shim does not process data; in this case, the physical interface is an Eth interface. When the chip's operating mode is configured in FlexE mode, the FlexE shim processes data; in this case, the physical interface is actually operating in FlexE mode, i.e., it is a FlexE interface.

[0106] It should be noted that the "physical interface supports being configured in FlexE mode" mentioned earlier refers to the fact that the port configuration mode of the physical port can be configured to FlexE mode. In other words, when configuring a physical port, in addition to configuring the chip operating mode of the physical interface, it is also necessary to configure the port configuration mode of the physical interface. Generally, for a physical interface, its port configuration mode and chip operating mode are consistent. For example, if the port configuration mode is FlexE mode, then the chip operating mode is also FlexE mode; similarly, if the port configuration mode is Eth mode, then the chip operating mode is also Eth mode. In one example, if the control management entity issues configuration command 1 to the communication device, instructing the communication device to configure physical port 1 to FlexE mode, then the communication device can configure both the port configuration mode and the chip operating mode of physical port 1 to FlexE mode based on configuration command 1. In another example, if the control management entity issues configuration instruction 2 to the communication device, instructing the communication device to configure physical port 1 to Eth mode, then the communication device can configure both the port configuration mode and the chip operating mode of physical port 1 to Eth mode based on configuration instruction 2.

[0107] The control and management entity mentioned in the embodiments of this application can be, for example, a device running network management system (NMS), or a controller. The control and management entity can be a functional module that implements control and / or management functions, or a physical entity running relevant functional modules. Such a physical entity can be, for example, a server with relevant software installed, which is used to implement the functions of the control and management entity. The embodiments of this application do not impose specific limitations.

[0108] Unless otherwise specified, the port mentioned in the embodiments of this application refers to the physical port of the communication device.

[0109] Next, we will introduce the possible application scenarios of this application.

[0110] See Figure 2a This figure is a schematic diagram of an exemplary application scenario provided by an embodiment of this application.

[0111] like Figure 2aAs shown, the control and management entity is connected to communication device A, which in turn is connected to communication device B. Communication device A communicates via port a and port b of communication device B. Both ports a and b operate in Eth mode. That is, both the port configuration mode and chip operating mode of port a and port b are in Eth mode. In this configuration, the control and management entity can manage communication device A and, through communication device A, manage communication device B (instructions issued by the control and management entity to communication device B are forwarded by communication device A).

[0112] If both ports a and b need to be switched from Eth mode to FlexE mode, the switching times of ports a and b cannot be strictly synchronized, which may cause communication failures between communication device A and communication device B. In one example: if port a is switched to FlexE mode first, both the configuration mode and chip operating mode of port a change to FlexE mode. At this time, port b remains in Eth mode, therefore, communication device A and communication device B cannot communicate normally. Furthermore, the control management entity can no longer manage communication device B (referred to as communication device B being disconnected), because the instructions issued by the control management entity to communication device B cannot be forwarded to communication device B through communication device A.

[0113] See Figure 2b This figure is a schematic diagram of an exemplary application scenario provided by an embodiment of this application.

[0114] like Figure 2b As shown, the control and management entity is connected to communication device A, which in turn is connected to communication device B. Communication device A communicates via port a and port b of communication device B. Both ports a and b operate in Eth mode. That is, both the port configuration mode and chip operating mode of port a and port b are in Eth mode. In this configuration, the control and management entity can manage communication device A and, through communication device A, manage communication device B.

[0115] If a communication device C is inserted between communication device A and communication device B, where port c of communication device C is used to communicate with port a, and port d of communication device C is used to communicate with port b, and both ports c and d operate in FlexE mode (i.e., both port c's port configuration mode and chip operating mode are FlexE mode, and both port d's port configuration mode and chip operating mode are FlexE mode), then because port a operates in Eth mode while port c operates in FlexE mode, communication device A and communication device C cannot communicate normally, thus causing communication device C to become disconnected from communication device B. Furthermore, because port b operates in Eth mode while port d operates in FlexE mode, communication device B and communication device C also cannot communicate normally.

[0116] See Figure 2c This figure is a schematic diagram of an exemplary application scenario provided by an embodiment of this application.

[0117] like Figure 2c As shown, the control and management entity is connected to communication device A, and communication device A is connected to communication device B. Communication device A communicates using port a and port b of communication device B. Both ports a and b operate in FlexE mode. That is, both the port configuration mode and chip operating mode of port a are FlexE mode; both the port configuration mode and chip operating mode of port b are FlexE mode. In this state, the control and management entity can manage communication device A and, through communication device A, manage communication device B.

[0118] If a communication device C is inserted between communication device A and communication device B, where port c of communication device C is used to communicate with port a, and port d of communication device C is used to communicate with port b, and both ports c and d operate in Eth mode (i.e., both port c's port configuration mode and chip operating mode are Eth mode, and both port d's port configuration mode and chip operating mode are Eth mode), then because port a operates in FlexE mode while port c operates in Eth mode, communication device A and communication device C cannot communicate normally, thus causing communication device C to become disconnected from communication device B. Furthermore, because port d operates in Eth mode while port b operates in FlexE mode, communication device B and communication device C also cannot communicate normally.

[0119] Based on the above Figure 2a , Figure 2b as well as Figure 2c As can be seen from the description, in the above scenarios, there is a phenomenon where two communication devices cannot communicate normally, and further, it can lead to some communication devices becoming disconnected.

[0120] In view of this, embodiments of this application provide an interface configuration method that can efficiently configure ports, thereby enabling normal communication between communication devices.

[0121] Next, the interface configuration method provided in the embodiments of this application will be briefly introduced with reference to the accompanying drawings.

[0122] See Figure 3 This figure is a signaling interaction diagram of the interface configuration method provided in the embodiment of this application. Figure 3 The interface configuration method 100 shown includes a communication device 1 with port 1 and a communication device 2 with port 2, wherein port 1 is used to communicate with port 2. Method 100 may include, for example, the following steps S101-S106.

[0123] S101: Communication device 1 determines that the chip operating mode of port 2 is Eth mode.

[0124] In one example, before executing S101, both the port configuration mode and the chip operating mode of port 1 are FlexE mode.

[0125] In some embodiments, if FlexE communication is established between communication device 1 and communication device 2, communication device 1 can receive FlexE overhead frames from communication device 2. Therefore, in one implementation, if communication device 1 does not receive a FlexE overhead frame sent by communication device 2 within a preset time, communication device 1 can determine that the chip operating mode of port 2 is Eth mode. Regarding FlexE overhead frames, please refer to section 7.3.1 of the Optical Internetworking Forum (OIF) Flex Ethernet 2.0 standard; it will not be described in detail here.

[0126] S102: Communication device 1 switches the chip operating mode of port 1 to Eth mode.

[0127] Since the chip operating mode of port 1 is FlexE mode and the chip operating mode of port 2 is Eth mode, ports 1 and 2 cannot communicate normally, meaning communication device 1 and communication device 2 cannot communicate normally. To enable normal communication between communication device 1 and communication device 2, in this embodiment, communication device 1 can switch the chip operating mode of port 1 to Eth mode. In this way, both the chip operating modes of port 1 and port 2 are in Eth mode, thus allowing communication device 1 and communication device 2 to communicate normally.

[0128] S103: Communication device 2 receives configuration instruction 1 sent by the control and management entity. Configuration instruction 1 is used to instruct communication device 2 to configure port 2 in FlexE mode.

[0129] In one example, before executing S103, both the port configuration mode and chip configuration mode of port 2 are in Eth mode.

[0130] In this embodiment, if the communication device 2 is directly connected to the control management entity, the control management entity can directly send the configuration instruction 1 to the communication device 2. If the communication device 2 and the control management entity also include a communication device 1, then after executing S102, the communication device 1 and the communication device 2 can communicate. Therefore, the control management entity can send the configuration instruction 1 to the communication device 2 through the communication device 1.

[0131] S104: Instruction information 1 sent by communication device 2 to communication device 1, the instruction information 1 being used to instruct communication device 1 to configure the chip operating mode of port 1 to FlexE mode.

[0132] S105: Communication device 2 configures both port configuration mode and chip operating mode of port 2 to FlexE mode.

[0133] After receiving the configuration instruction 1, in order to ensure that communication device 1 and communication device 2 can still communicate normally after configuring port 2 based on the configuration instruction 1, communication device 2 can send instruction information 1 to communication device 1 before configuring port 2 based on the configuration instruction 1. Instruction information 1 is used to instruct communication device 1 to configure the chip working mode of port 1 to FlexE mode.

[0134] Regarding S105, it should be noted that in one implementation, after receiving configuration instruction 1, communication device 2 can immediately configure the port configuration mode of port 2 to FlexE mode, then send instruction information 1 to communication device 1, and after sending instruction information 1 to communication device 1, configure the chip operating mode of port 2 to FlexE mode. In another implementation, communication device 2 can, after sending instruction information 1 to communication device 1, configure both the port configuration mode and the chip operating mode of port 2 to FlexE mode.

[0135] This application does not specifically limit the indication information 1. In one example, the indication information 1 can be a remote fault (RF) indication. The RF indication is the PCS layer RF interrupt signal in the Institute of Electrical and Electronics Engineers (IEEE) 802.3Eth standard. For details on RF indication, please refer to the relevant descriptions in the IEEE 802.3Eth standard; they will not be elaborated upon here.

[0136] In another example, the indication information 1 can be a 00 code block in Ethernet frame 1. When the received 00 code block value is 0x00, it indicates that the chip operating mode of the transmitting port is Eth mode; when the received 00 code block value is 0x05, it indicates that the chip operating mode of the transmitting port is FlexE mode. For related explanations of the 00 code block, please refer to the relevant description in section 82.2.3.3 of IEEE 802.3-2015, which will not be detailed here. In this embodiment, if the indication information 1 is a 00 code block in Ethernet frame 1, then the value of the 00 code block can be 0x05.

[0137] In yet another example, the aforementioned indication information 1 can be carried in Ethernet frame 1 sent by communication device 2 to communication device 1. This Ethernet frame 1 may include an extended type length value (TLV) field used to carry the indication information 1. In one implementation, a new type of Ethernet frame can be defined to carry the indication information 1. See also... Figure 4 , Figure 4 This is a schematic diagram of the structure of an Ethernet frame 1 provided in an embodiment of this application.

[0138] like Figure 4 As shown, the Ethernet frame 1 includes a destination address field, a source address field, a type field, a chip operating mode switching notification field, and a frame check sequence (FCS) field. The definitions of the destination address field, source address field, and type field can be found in section 3.1.1 of IEEE 802.3-2015 for Eth frames, and will not be detailed here. In this embodiment, the chip operating mode switching notification field can be an extended TLV field, which carries the aforementioned indication information 1. In one example, as... Figure 4As shown, the chip operating mode switching notification field may include a message version field, a message type field, a message length field, and a message TLV field. The message TLV field may include a TLV type field, a TLV length field, and a TLV value field.

[0139] for Figure 4 In the Ethernet frame 1 shown, the indication information 1 can be carried by the message type field, or it can be carried by both the message type field and the message TLV field. This application embodiment does not make specific limitations.

[0140] Regarding Ethernet frame 1 shown in Figure 1, in one example, the value of the type field can be 0x9100, the value of the messagevesion field can be 0, the value of the message type can be 1, the value of the message length is the length of Ethernet frame 1, the value of the TLV type field can be 1, the content of the TLV length field is the string "HUAWEI ETH SWITCHFLEXE", and the value carried by the TLV value is the length of the string "HUAWEI ETH SWITCH FLEXE".

[0141] In one implementation of this application, to ensure that communication device 1 can receive the indication information 1, communication device 2 can periodically send the indication information 1 to communication device 1 within a predetermined time period. Taking the indication information 1 as an RF indication as an example, in this application embodiment, communication device 2 can periodically send the RF indication to communication device 1 within 20 milliseconds, for example. This application embodiment does not specifically limit the predetermined time period; the duration of the predetermined time period can be, for example, less than 1 second. The reason for this is that if communication device 1 receives the RF indication for more than 1 second, communication device 1 will trigger an alarm.

[0142] S106: Communication device 1 configures the chip operating mode of port 1 to FlexE mode according to instruction information 1.

[0143] In one example, after receiving instruction information 1, communication device 1 can configure the chip operating mode of port 1 to FlexE mode based on instruction information 1. In this way, both the port configuration mode and the chip operating mode of port 1 are FlexE mode, and both the port configuration mode and the chip operating mode of port 2 are FlexE mode. Therefore, FlexE communication can be performed normally between port 1 and port 2.

[0144] In one implementation of this application embodiment, after executing S106, the communication device 1 can periodically detect the chip operating mode of port 2, and when the chip operating mode of port 2 is different from the chip operating mode of port 1, configure the chip operating mode of port 1 so that the chip operating mode of port 1 is consistent with the chip operating mode of port 2.

[0145] As an example: After executing S106, the chip operating mode of port 1 is FlexE mode. If communication device 1 determines that the chip operating mode of port 2 is Eth mode, then communication device 1 can configure the chip operating mode of port 1 to Eth mode, thereby making the chip operating mode of port 1 the same as that of port 2, thus enabling communication between port 1 and port 2. The specific implementation of communication device 1 determining that the chip operating mode of port 2 is Eth mode can be found in the description of S101 above, and will not be detailed here.

[0146] As another example: After communication device 1 can configure the chip operating mode of port 1 to Eth mode, if communication device 1 determines that the chip operating mode of port 2 is FlexE mode, then communication device 1 can configure the chip operating mode of port 1 to FlexE mode, so that the chip operating mode of port 1 is the same as the chip operating mode of port 2, thereby enabling communication between port 1 and port 2.

[0147] In this embodiment of the application, the communication device 1 determines that the chip working mode of port 2 is FlexE mode. In specific implementation, there are multiple implementation methods. Several possible implementation methods are introduced below.

[0148] In one implementation: considering that if the chip operating mode of port 2 is Eth mode, then port 1 can receive a block lock signal from port 2. Therefore, if communication device 1 does not receive a block lock signal from communication device 2 within a preset time period, it can be determined that the chip operating mode of port 2 is FlexE mode. For details regarding the block lock signal, please refer to the relevant description in section 82.2.19.3 of IEEE 802.3-2015; it will not be elaborated upon here.

[0149] In one implementation: considering that if the chip operating mode of port 2 is Eth mode, then port 1 can receive the alignment marker lock signal from port 2. Therefore, if communication device 1 does not receive the alignment marker lock signal sent by communication device 2 within a preset time period, it can be determined that the chip operating mode of port 2 is FlexE mode. Regarding the alignment marker lock signal, please refer to the relevant description in section 82.2.19.3 of IEEE 802.3-2015; it will not be detailed here.

[0150] In one implementation: communication device 1 can determine the chip operating mode of port 2 based on the value of the O0 code block sent by communication device 2. Specifically: when the value of the O0 code block sent by communication device 2 is 0x05, communication device 1 can determine that the chip operating mode of port 2 is FlexE mode; when the value of the O0 code block sent by communication device 2 is 0x00, communication device 1 can determine that the chip operating mode of port 2 is Eth mode.

[0151] In one implementation: Communication device 1 can send an Ethernet frame 2 to communication device 2. The Ethernet frame 2 may include indication information 2, which is used to determine whether the chip operating mode of port 2 is Eth mode. If the chip operating mode of port 2 is Eth mode, then communication device 2 can send a response to the Ethernet frame 2 to communication device 1. If the chip operating mode of port 2 is FlexE mode, then communication device 2 cannot correctly parse the Ethernet frame 2, and therefore communication device 2 will not send a response to the Ethernet frame 2 to communication device 1. Therefore, in this case, if communication device 1 does not receive a response to the Ethernet frame 2 from communication device 2 after sending the Ethernet frame 2, then communication device 1 can determine that the chip operating mode of port 2 is Eth mode.

[0152] Regarding EtherFrame 2, it should be noted that the structure of EtherFrame 2 can be found in [reference needed]. Figure 4 In one example, the indication information 2 can be carried by the message type field of Ethernet frame 2, or it can be carried by both the message type field and the message TLV field of Ethernet frame 2. This application embodiment does not make specific limitations.

[0153] For example, indication information 2 can be carried by the message type field of Ethernet frame 2, and the value of the message type field of Ethernet frame 2 can be 2. Alternatively, indication information 2 can be carried by both the message type field and the message TLV field of Ethernet frame 2. In this case, the value of the message type field of Ethernet frame 2 can be 1, and the value of the TLV type field of Ethernet frame 2 can be 2. Furthermore, the TLV value field of Ethernet frame 2 can also be used, for example, to indicate that the chip operating mode of port 1 is Eth mode; this embodiment of the application does not impose specific limitations.

[0154] In this embodiment of the application, the response sent by the communication device 2 to the communication device 1 in response to the Ethernet frame 2 may be, for example, an Ethernet frame 3. The Ethernet frame 3 includes indication information 3, which is used to indicate the response.

[0155] Regarding EtherFrame 3, it should be noted that the structure of EtherFrame 3 can be found in [reference needed]. Figure 4 In one example, the indication information 3 can be carried by the message type field of Ethernet frame 3, or it can be carried by both the message type field and the message TLV field of Ethernet frame 3. This application embodiment does not make specific limitations.

[0156] For example, indication information 3 can be carried by the message type field of Ethernet frame 3, and the value of the message type field of Ethernet frame 3 can be 3. Alternatively, indication information 3 can be carried by both the message type field and the message TLV field of Ethernet frame 3. In this case, the value of the message type field of Ethernet frame 3 can be 1, and the value of the TLV type field of Ethernet frame 3 can be 3. Furthermore, the TLV value field of Ethernet frame 3 can also be used, for example, to indicate that the chip operating mode of port 2 is Eth mode; this embodiment of the application does not impose specific limitations.

[0157] In one implementation of this application, when the port configuration mode of port 1 is FlexE mode and the chip operating mode is Eth mode, communication device 1 can send indication information 4 to communication device 2. Indication information 4 instructs communication device 2 to configure the chip operating mode of port 2 to FlexE mode. After receiving indication information 4, if the chip operating mode of port 2 is FlexE mode, communication device 2 can ignore indication information 4. If the chip operating mode of port 2 is FlexE mode, communication device 2 can configure the chip operating mode of port 2 to FlexE mode based on indication information 4.

[0158] Correspondingly, if port 2's port configuration mode is FlexE mode and its chip operating mode is Eth mode, communication device 2 can also send instruction information 5 to communication device 1. Instruction information 5 instructs communication device 1 to configure port 1's chip operating mode to FlexE mode. In this case, after receiving instruction information 5, communication device 1 can configure port 1's chip operating mode to FlexE mode. And after receiving instruction information 4, communication device 2 can configure port 2's chip operating mode to FlexE mode. In this way, communication device 1 and communication device 2 can perform FlexE communication.

[0159] The above has introduced method 100. The following section describes how to apply some or all of the steps in method 100 to… Figure 2a , Figure 2b as well as Figure 2c The specific implementation method in the scenario shown.

[0160] for Figure 2a Application scenarios shown:

[0161] First, the control management entity sends configuration command a to communication device A, instructing communication device A to configure port a to FlexE mode. Based on configuration command a, communication device A configures both the port configuration mode and chip operating mode of port a to FlexE mode. Then, communication device A determines that the chip operating mode of port b is Eth mode, and therefore configures the chip operating mode of port a to Eth mode. The control management entity then sends configuration command b to communication device B through communication device A, instructing communication device B to configure port b to FlexE mode. Upon receiving configuration command b, communication device B sends instruction information 1 to communication device A, instructing communication device A to configure the chip operating mode of port a to FlexE mode. Upon receiving instruction information 1, communication device A switches the chip operating mode of port a to FlexE mode. After receiving configuration command b, communication device B configures the port configuration mode of port b to FlexE mode, and after sending instruction information 1 to communication device A, configures the chip operating mode of port b to FlexE mode. Thus, both port a and port b enable the switching from Eth mode to FlexE mode, allowing FlexE communication between communication device A and communication device B, and communication device B will not become unmanaged.

[0162] for Figure 2b Application scenarios shown:

[0163] First, communication device C determines that the chip operating mode of port a is Eth mode, therefore, communication device C configures the chip operating mode of port c to Eth mode. Communication device C determines that the chip operating mode of port b is Eth mode, therefore, communication device C configures the chip operating mode of port d to Eth mode. Then, the control management entity sends a configuration command c to communication device C through communication device A. Configuration command c instructs communication device C to configure ports c and d to Eth mode. After receiving configuration command c, communication device C configures the port configuration mode of both ports c and d to Eth mode. Thus, both ports c and d have achieved a switch from FlexE mode to Eth mode, enabling Eth communication between communication devices A and C, as well as between communication devices B and C, without disconnecting from communication device C.

[0164] for Figure 2c Application scenarios shown:

[0165] Communication device A determines that the chip operating mode of port c is Eth mode, therefore communication device A configures the chip operating mode of port a to Eth mode. The control management entity sends a configuration command d to communication device C through communication device A. Configuration command d instructs communication device C to configure both ports c and d to FlexE mode. After receiving configuration command d, communication device C sends instruction information 1 to communication device A, instructing communication device A to configure the chip operating mode of port a to FlexE mode.
