Description

TECHNICAL FIELD

[0002] Network devices in an Ethernet cannot exist in a loop connection. For example, the network devices can be core devices, aggregation devices or access devices, etc.

[0003] At present, an anti-loop protocol can be configured in the network devices to avoid the network devices from appearing in a loop through the anti-loop protocol. For example, the anti-loop protocol can be a multi-service transport platform (MSTP) protocol. However, the principle of the anti-loop protocol is relatively complex, and especially in the case of a complex network topology, the administrator needs to perform a relatively complex configuration on the network devices, otherwise the network devices can block the non-expected ports through the anti-loop protocol. The above method leads to a high anti-loop complexity of the network devices. SUMMARY

[0077] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0078] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0079] To facilitate understanding, let's first combine Figure 1 The application scenarios of the embodiments of this application will be described.

[0080] Figure 1 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. Please refer to [link / reference]. Figure 1 Ethernet can be a three-layer network. Layer 1 can include core device A, Layer 2 can include aggregation device A and aggregation device B, and Layer 3 can include access device A and access device B. Core device A can be connected to both aggregation device A and aggregation device B. Aggregation device A can also be connected to access device A, and aggregation device B can also be connected to access device B.

[0081] The core device can also connect to a control device (not shown in the figure) to obtain configuration information from the control device. For example, the control device can be a Software Defined Network (SDN) controller.

[0082] It should be noted that an Ethernet network may include fewer or more layers than shown in the diagram, and each layer may include one or more network devices (in this application, core devices, aggregation devices, and access devices are collectively referred to as network devices). Figure 1 Ethernet is described by way of example only and does not constitute a limitation on the technical solutions provided in the embodiments of this application.

[0083] In the network architecture described above, no network device can be connected in a loop. For example, a loop connection can be a dual uplink, dual homing, stacked interconnect, or Virtual Router Redundancy Protocol (VRRP) connection.

[0084] Below, in conjunction with Figure 2 This section explains the situation where loops exist in network devices.

[0085] Figure 2 This is a schematic diagram illustrating the connection of a network device according to an embodiment of this application. Please refer to... Figure 2 Core device A can be connected to aggregation device A and aggregation device B respectively. Core device B can be connected to aggregation device B and aggregation device C respectively. Access device A can be connected to aggregation device A. Access device B can be connected to aggregation device B and aggregation device C respectively.

[0086] Depend on Figure 2 It can be seen that aggregation device B is connected to both core device A and core device B, and access device B is connected to both aggregation device B and aggregation device C. Therefore, there is a loop connection between aggregation device B and access device B.

[0087] It should be noted that before powering on network equipment, technicians typically connect the network equipment to other network devices. However, the network topology in Ethernet is quite complex, and properly connected cables can often lead to loop connections within the network equipment.

[0088] Currently, loop prevention protocols can be used to disrupt loop connections in network devices, thus preventing loop connections from occurring. For example, the MSTP protocol can be used for loop prevention.

[0089] Specifically, loop prevention protocols can be pre-configured in network devices before they leave the factory. During power-up, the network device can use these protocols to break its own loop connections. However, loop prevention protocols are generally only applicable to Layer 2 networks. In complex network topologies, if a network device breaks its own loop connection using the loop prevention protocol, administrators need to perform complex configurations on the network device; otherwise, the network device may block unexpected ports using the loop prevention protocol. This method results in high complexity for loop prevention in network devices. Therefore, some network devices are not pre-configured with loop prevention protocols before leaving the factory.

[0090] In view of this, embodiments of this application provide a port setting method. In this method, a network device can receive its own tier number in the Ethernet network, and / or the tier numbers of its neighboring devices in the Ethernet network. Based on the received tier number, the network device can determine the target port causing the loop connection among its multiple ports and set the target port to an unavailable state. This avoids loop connections in the network device without requiring a loop prevention protocol to break the loop connection, thus reducing the complexity of loop prevention for the network device.

[0091] Furthermore, the method provided in this application does not limit the number of Ethernet network layers; the Ethernet network can have two or more layers. In other words, the above method can be applied to network devices in multi-layer networks, resulting in better loop prevention flexibility.

[0092] Furthermore, the port configuration method provided in this application embodiment eliminates the need for administrators to perform complex configurations of network devices, simplifying network device configuration. If a network device malfunctions, the simplified configuration allows administrators to quickly locate the fault, resulting in high fault handling efficiency.

[0093] Furthermore, when a network device breaks a loop using the method provided in this application embodiment, no configuration is required before the network device leaves the factory. For example, no anti-loop protocol needs to be configured for the network device before it leaves the factory. In other words, the port setting method provided in this application embodiment is applicable to network devices in zero-configuration scenarios.

[0094] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0095] Figure 3This is a flowchart illustrating a port setting method provided in an embodiment of this application. The executing entity of this method can be a network device or a port setting device installed in the network device. The port setting device can be implemented by software or by a combination of software and hardware. For ease of understanding, the following explanation uses a network device as the executing entity. Please refer to... Figure 3 The method may include:

[0096] S301, Receive at least one existing level number.

[0097] At least one existing tier number includes the tier number of the network device in the Ethernet, and / or the tier number of the network device's neighboring devices in the Ethernet.

[0098] For any existing tier number, when a network device receives an existing tier number, it can receive tier configuration information. The tier configuration information includes the existing tier number and a target field. The target field is used to indicate that the existing tier number is the tier number of the network device in the Ethernet, or to indicate that the existing tier number is the tier number of the network device's neighboring device in the Ethernet.

[0099] In this embodiment, the network device can receive hierarchical configuration information through the port based on the communication protocol.

[0100] The port can be a port configured on the network device to connect to neighboring devices or to control devices. For example, neighboring devices can be core devices, aggregation devices, or access devices, while the control device can be an SDN controller.

[0101] The communication protocol can be the Link Layer Discovery Protocol (LLDP), or it can be the Network Configuration (NETCONF) protocol based on the Extensible Markup Language (XML) protocol.

[0102] Network devices can communicate with their neighbors via the LLDP protocol. The existing tier number sent by a neighbor to the network device can be its tier number within the Ethernet network. In other words, the existing tier number included in the tier configuration information received by the network device via the LLDP protocol can be the tier number of its neighbor within the Ethernet network.

[0103] Network devices can communicate with control devices via the NETCONF protocol. The existing layer number sent by the control device to the network device can be the network device's layer number within the Ethernet network. In other words, the existing layer number included in the layer configuration information received by the network device via the NETCONF protocol can be the network device's layer number within the Ethernet network.

[0104] For any given hierarchical configuration information, the target field included in the hierarchical configuration information can be used to indicate the communication protocol receiving the hierarchical configuration information. For example, the target field can be an identifier of the communication protocol. In other words, the target field can be used to indicate that the existing hierarchical number included in the hierarchical configuration information is the hierarchical number of the network device in the Ethernet, or to indicate that the existing hierarchical number is the hierarchical number of the network device's neighboring device in the Ethernet.

[0105] In this embodiment, at least one existing hierarchical number includes at least the following three cases:

[0106] Case 1: At least one existing tier number is the tier number of the network device in the Ethernet.

[0107] In this scenario, the network device is not connected to other network devices, but only to the control device. The network device can be a core device.

[0108] Case 2: At least one existing tier number is the tier number of the network device's neighboring device in the Ethernet.

[0109] In this scenario, the network device does not communicate with the control device but only connects to other network devices. These network devices can be aggregation devices or access devices, etc.

[0110] Case 3: At least one existing tier number includes the tier number of the network device in the Ethernet and the tier number of the network device's neighboring devices in the Ethernet.

[0111] In this scenario, the network device connects to both other network devices and control equipment. The network device can be a core device.

[0112] S302. Determine the target port from among multiple ports of the network device based on at least one existing hierarchical number.

[0113] The target port can be one of the multiple ports on the network device that needs to be set to an unavailable state.

[0114] In this embodiment, if at least one existing hierarchical number is the hierarchical number of the network device in the Ethernet, or if at least one existing hierarchical number includes the hierarchical number of the network device in the Ethernet and the hierarchical numbers of the network device's neighboring devices in the Ethernet, then the network device can be a core device. The network device can identify the target port from among its multiple ports, excluding the port communicating with the control device.

[0115] If at least one existing tier number is the tier number of a neighboring device in the Ethernet network, then the network device can be an aggregation device or an access device. The network device can determine any one of its multiple ports to connect to a higher-level device, and can designate any port other than the one connected to the higher-level device as the target port. The higher-level device can be a neighboring device with a tier number lower than that of the network device.

[0116] S303, Set the target port to an unavailable state, and / or set the remaining ports to an available state.

[0117] The remaining ports are those other than the target port among multiple ports.

[0118] When the target port is set to unavailable, the network device can determine whether there is a connection port in the target port. The connection port is the port connected to the network device's neighboring device. If there is a connection port in the target port, the status of the connection port is set to unavailable in the port configuration information to achieve the purpose of setting the target port to unavailable.

[0119] Port configuration information can be used to set the port status. It's important to note that if the port status is set to unavailable in the port configuration information for any given port, the network device will be unable to communicate with neighboring devices through that port.

[0120] Specifically, when setting the target port to an unavailable state, you can set the status of the connection ports within the target port to an unavailable state. It should be noted that the ports in the target port other than the connection ports can be ports that are not connected to other network devices; therefore, it is not necessary to set the status of the ports in the target port other than the connection ports.

[0121] When setting other ports to an available state, you can do so in the port configuration information. It's important to note that for any given port, if its status is set to available in the port configuration information, the network device can communicate with neighboring devices through that port.

[0122] In the port setting method provided in this embodiment, the network device can receive at least one existing hierarchical number and determine the target port from among multiple ports of the network device based on the at least one existing hierarchical number; the target port can be set to an unavailable state, and / or the remaining ports can be set to an available state, wherein the remaining ports are the ports other than the target port among the multiple ports. Through the above method, loop connections in Ethernet network devices can be avoided, and loop prevention protocols are not required to break loop connections, thus reducing the complexity of loop prevention for network devices.

[0123] Based on any of the above embodiments, the following is combined with Figure 4 The port setting method provided in the embodiments of this application will be further explained.

[0124] Figure 4 This is a flowchart illustrating another port setting method provided in an embodiment of this application. The executing entity of this method can be a network device or a port setting device installed in the network device. The port setting device can be implemented by software or by a combination of software and hardware. For ease of understanding, the following explanation uses a network device as the executing entity. Please refer to... Figure 4 The method may include:

[0125] S401, Receive at least one existing level number.

[0126] It should be noted that the specific implementation of S401 can be found in S301, and will not be repeated here.

[0127] S402. Determine whether a first-level number exists in at least one existing level number.

[0128] If at least one of the existing level numbers contains a first level number, execute S403;

[0129] If at least one of the existing level numbers does not contain a first level number, execute S404.

[0130] The first-level number is the tier number of the network device in the Ethernet. In other words, the first-level number can be an existing tier number that the network device obtains from the control device.

[0131] The first-level number can be the layer number set by the control device for the network device, or the layer number of the network device in the Ethernet.

[0132] S403. Determine the target port from among the multiple ports, excluding the port that receives the first-level number.

[0133] In this embodiment, if at least one existing hierarchical number contains a first-level number, the network device can be a core device. The network device can designate all ports except those receiving the first-level number as target ports. In other words, the network device can designate all ports except those connected to the control device as target ports.

[0134] S404. Determine the first level number based on at least one existing level number.

[0135] In this embodiment, if at least one existing tier number does not contain a first-tier number, the network device is either an aggregation device or an access device. At least one existing tier number can be the tier number of the network device's neighboring devices within the Ethernet network. The neighboring devices of the network device can be either its parent device or its sibling device. For example, if the network device is a Layer 2 network, its parent device can be a Layer 1 network device, and its sibling device can be a Layer 2 network device.

[0136] It should be noted that the hierarchical number of the superior device of a network device is smaller than the hierarchical number of the network device itself, while the hierarchical number of the peer device of a network device is the same as the hierarchical number of the network device.

[0137] In this embodiment, if the first level number is not present in at least one existing level number, the network device can determine the first level number based on at least one existing level number. In other words, the network device can determine its own level number based on at least one existing level number.

[0138] On the one hand, once a network device determines its first-level identifier, it can send that identifier to its neighboring devices. On the other hand, determining the first-level identifier makes it easier to identify the target port.

[0139] In this embodiment, when determining the first level number, the network device can determine the minimum value among at least one existing level number; the sum of the minimum value and a preset value is determined as the first level number.

[0140] It should be understood that the minimum value among at least one existing hierarchical number can be the hierarchical number of the network device's parent device. It should be noted that if at least one existing hierarchical number is the same, the network device can determine any one of the existing hierarchical numbers as the minimum value among at least one existing hierarchical number.

[0141] In this embodiment, the hierarchical number of the network device (i.e., the first hierarchical number) is 1 greater than the hierarchical number of the network device's parent device, so the preset value can be 1.

[0142] The hierarchical number of the network device's parent device is the minimum value among at least one existing hierarchical number. In practice, the first hierarchical number can be determined by adding the minimum value among at least one existing hierarchical number to 1.

[0143] For example, assuming that at least one existing level number includes 1, 1, 2, 2 and 2, then the minimum value among the at least one existing level number can be 1, and the first level number can be 2.

[0144] It should be noted that in other embodiments, if the difference between the hierarchical number of the network device and the hierarchical number of the network device's parent device is a different value, the preset value can also be a different value.

[0145] S405. Determine the target port from among multiple ports based on at least one existing level number and the first level number.

[0146] In this embodiment, the network device can determine a first port and a second port among multiple ports. The first port is a port that receives at least one existing hierarchical number, and the second port is a port other than the first port among the multiple ports. The second port is determined as the first target port. Based on at least one existing hierarchical number and the first hierarchical number, the second target port is determined among the first ports. The target port includes the first target port and the second target port.

[0147] When determining the second target port from the first port based on at least one existing hierarchical number and the first hierarchical number, the network device can determine a second hierarchical number and a third hierarchical number from at least one existing hierarchical number, wherein the second hierarchical number is equal to the first hierarchical number, the number of second hierarchical numbers is greater than or equal to zero, the third hierarchical number is less than the first hierarchical number, and the number of third hierarchical numbers is greater than or equal to 1; the port in the first port that receives the second hierarchical number is determined as the first candidate port; the port in the first port that receives the third hierarchical number is determined as the second candidate port, and a third candidate port is determined from the second candidate ports according to a preset rule; the first candidate port and / or the third candidate port are determined as the second target port.

[0148] The second-level number is equal to the first-level number. In other words, the second-level number can be an existing level number sent by a peer device to the network device.

[0149] The third-level number is less than the first-level number. In other words, the third-level number can be an existing level number sent from the network device's parent device to the network device.

[0150] The preset rules can be set according to the actual rules, but this embodiment does not limit this.

[0151] In one possible implementation, the preset rule can be: sort the second candidate ports in descending order of port number, and determine the other ports in the second candidate ports, except for the port with the smallest port number, as the third candidate ports.

[0152] In another possible implementation, the preset rule can be: sort the second candidate ports in descending order of port number, and determine the other ports in the second candidate ports, except for the port with the largest port number, as the third candidate ports.

[0153] S406. Set the target port to an unavailable state, and / or set the remaining ports to an available state.

[0154] It should be noted that the specific implementation of S406 can be found in S303, and will not be repeated here.

[0155] S407. Power off the connection port first, then power it on.

[0156] The connection port can be one of the ports that is connected to a neighboring device.

[0157] In this embodiment, after setting the target port to an unavailable state and setting the remaining ports to an available state, the connection ports can be powered down and then powered on. It should be understood that the connection ports include the target port and / or the remaining ports.

[0158] It should be noted that powering down and then powering on the connection port can clear any incorrect Media Access Control Addresses (MACs) that the network device has learned.

[0159] Below, in conjunction with Figure 5 This explains the incorrect MAC addresses learned by the network device.

[0160] Figure 5 This is a connection diagram of another network device provided in an embodiment of this application. Please refer to... Figure 5 The core equipment is connected to the aggregation equipment, and the aggregation equipment is connected to the access equipment through port A and port B.

[0161] Suppose that after the aggregation device receives a message from the core device, it sends a message to the access device through port A, and then retrieves a message from the access device through port B. This message propagation process results in the aggregation device learning the MAC address of the core device on port B. In other words, the aggregation device has learned an incorrect MAC address. Waiting for the aggregation device to automatically clear this incorrect MAC address would take a considerable amount of time.

[0162] In this embodiment, by powering down first and then powering on, incorrect MAC addresses learned by the network device can be quickly cleared.

[0163] The port setting method provided in this embodiment allows the network device to receive at least one existing hierarchical number and determine whether a first hierarchical number exists among the at least one existing hierarchical number. If a first hierarchical number exists among the at least one existing hierarchical number, the port other than the port receiving the first hierarchical number can be designated as the target port. If a first hierarchical number does not exist among the at least one existing hierarchical number, a first hierarchical number can be determined based on the at least one existing hierarchical number, and the target port can be determined among the multiple ports based on the at least one existing hierarchical number and the first hierarchical number. After determining the target port, the network device can set the target port to an unavailable state and / or set the remaining ports to an available state. This method avoids loop connections in Ethernet networks without requiring loop prevention protocols to break loop connections, thus reducing the complexity of loop prevention for network devices.

[0164] Below, in conjunction with Figure 6 The port setting method provided in the embodiments of this application will be explained through specific examples.

[0165] Figure 6 This is a connection diagram of another network device provided in an embodiment of this application. Please refer to... Figure 6 Core device 1 can connect to port 31 of aggregation device 3 via port 11, to port 41 of aggregation device 4 via port 12, and to port 51 of aggregation device 5 via port 13. Core device 2 can connect to port 32 of aggregation device 3 via port 21, to port 42 of aggregation device 4 via port 22, and to port 52 of aggregation device 5 via port 23. Aggregation device 3 can also connect to port 43 of aggregation device 4 via port 33, and to port 44 of aggregation device 4 via port 34. Access device 6 can connect to port 35 of aggregation device 3 via port 61, and to port 45 of aggregation device 4 via port 62. Access device 7 can connect to port 36 of aggregation device 3 via port 71, and to port 46 of aggregation device 4 via port 72. Access device 8 can connect to port 53 of aggregation device 5 via port 81, and to port 54 of aggregation device 5 via port 82.

[0166] In this embodiment, it is assumed that the preset rule is: sort the second candidate ports (i.e., the ports connected to the upper-level device) in descending order of port number, and determine the other ports in the second candidate ports, except for the port with the smallest port number, as the third candidate ports.

[0167] Taking aggregation device 3 as an example Figure 4 Taking the network device shown in the embodiment as an example, aggregation device 3 has ports 31, 32, 33, 34, 35, and 36. When aggregation device 3 is powered on, access devices (e.g., access device 6 or access device 7) are not powered on, while core devices (e.g., core device 1 and core device 2) and aggregation devices (e.g., aggregation device 4) can be in a powered-on state. Therefore, aggregation device 3 can receive at least one existing tier number sent by core device 1, core device 2, and aggregation device 4 through ports 31, 32, 33, and 34. Aggregation device 3 can designate ports 31, 32, 33, and 34 as first ports, and ports 35 and 36 as second ports. The existing tier number received by aggregation device 3 through ports 33 and 34 can be a second tier number, and the existing tier number received through ports 31 and 32 can be a third tier number. Aggregation device 3 can designate ports 33 and 34 as first candidate ports, and ports 31 and 32 as second candidate ports. Aggregator 3 can determine port 32 as the third candidate port according to preset rules. In summary, aggregation device 3 can determine the second port (ports 35 and 36), the first candidate port (ports 33 and 34), and the third candidate port (port 32) as the target port. Figure 6 (In the diagram, B can represent the target port). It should be noted that when aggregation device 3 is powered on, the access devices (such as access device 6 or access device 7) are not powered on. Aggregation device 3 can identify the port on aggregation device 3 connected to the access device as the target port. If the access device powers on and sets the port on the access device connected to aggregation device 3 to an available state, the corresponding port on aggregation device 3 can automatically become available.

[0168] Using aggregation device 4 as Figure 4Taking the network device shown in the embodiment as an example, aggregation device 4 has ports 41, 42, 43, 44, 45, and 46. When aggregation device 4 is powered on, access devices (e.g., access device 6 or access device 7) are not powered on, while core devices (e.g., core device 1 and core device 2) and aggregation devices (e.g., aggregation device 3) can be in a powered-on state. Therefore, aggregation device 4 can receive at least one existing tier number sent by core device 1, core device 2, and aggregation device 3 through ports 41, 42, 43, and 44. Aggregation device 4 can designate ports 41, 42, 43, and 44 as first ports and ports 45 and 46 as second ports. The existing tier number received by aggregation device 4 through ports 43 and 44 can be a second tier number, and the existing tier number received through ports 41 and 42 can be a third tier number. Aggregation device 4 can designate ports 43 and 44 as first candidate ports and ports 41 and 42 as second candidate ports. Aggregator 4 can determine port 42 as the third candidate port according to preset rules. In summary, aggregation device 4 can determine the second port (ports 45 and 46), the first candidate port (ports 43 and 44), and the third candidate port (port 42) as the target port. Figure 6 (In the diagram, B can represent the target port). It should be noted that when aggregation device 4 is powered on, the access devices (such as access device 6 or access device 7) are not powered on. Aggregation device 4 can identify the port on aggregation device 4 connected to the access device as the target port. If the access device powers on and sets the port on the access device connected to aggregation device 4 to an available state, the corresponding port on aggregation device 4 can automatically become available.

[0169] Using aggregation device 5 as Figure 4 Taking the network device shown in the embodiment as an example, the aggregation device 5 has ports 51, 52, 53, and 54. When the aggregation device 5 is powered on, the access devices (e.g., access device 8) are not powered on, while the core devices (e.g., core device 1 and core device 2) are powered on. Therefore, the aggregation device 5 can receive at least one existing tier number sent by core device 1 and core device 2 through ports 51 and 52. The aggregation device 5 can determine ports 51 and 52 as the first port and ports 53 and 54 as the second port. The existing tier number received by the aggregation device 5 through ports 51 and 52 can be a third tier number. The aggregation device 5 can determine ports 51 and 52 as the second candidate port. The aggregation device 5 can determine port 52 as the third candidate port according to preset rules. In summary, the aggregation device 5 can determine the second port (ports 53 and 54) and the third candidate port (port 52) ​​as the target port. Figure 6(In the diagram, B can represent the target port). It should be noted that when aggregation device 5 is powered on, access device 8 is not powered on. Aggregation device 5 can identify the port on aggregation device 5 connected to access device 8 as the target port. If access device 8 is powered on and sets the port on access device 8 connected to aggregation device 5 to an available state, then the corresponding port on aggregation device 5 can automatically become available.

[0170] Taking access device 6 as an example Figure 4 Taking the network device shown in the embodiment as an example, access device 6 has ports 61 and 62. When access device 6 is powered on, the aggregation devices (e.g., aggregation devices 3 and 4) are also powered on. Therefore, access device 6 can receive at least one existing tier number sent by aggregation devices 3 and 4 through ports 61 and 62. Access device 6 can determine ports 61 and 62 as the first port. The existing tier number received by access device 6 through ports 61 and 62 can be the third tier number. Access device 6 can determine ports 61 and 62 as the second candidate port. Access device 6 can determine port 62 as the third candidate port according to preset rules. In summary, access device 6 can determine the third candidate port (port 62) as the target port. Figure 6 (B in the diagram can represent the target port). After access device 6 sets port 61 to an available state, port 35 on aggregation device 3 can automatically be switched to an available state.

[0171] Taking access device 7 as an example Figure 4 Taking the network device shown in the embodiment as an example, access device 7 has ports 71 and 72. When access device 7 is powered on, the aggregation devices (e.g., aggregation devices 3 and 4) are also powered on. Therefore, access device 7 can receive at least one existing tier number sent by aggregation devices 3 and 4 through ports 71 and 72. Access device 7 can determine ports 71 and 72 as the first port. The existing tier number received by access device 7 through ports 71 and 72 can be the third tier number. Access device 7 can determine ports 71 and 72 as the second candidate port. Access device 7 can determine port 72 as the third candidate port according to preset rules. In summary, access device 7 can determine the third candidate port (port 72) as the target port. Figure 6 (B in the diagram can represent the target port). After access device 7 sets port 71 to an available state, port 36 on aggregation device 3 can automatically be switched to an available state.

[0172] Taking access device 8 as an example Figure 4Taking the network device shown in the embodiment as an example, access device 8 has ports 81 and 82. When access device 8 is powered on, the aggregation device (e.g., aggregation device 5) is also powered on. Therefore, access device 8 can receive at least one existing tier number sent by aggregation device 5 through ports 81 and 82. Access device 8 can determine ports 81 and 82 as the first port. The existing tier number received by access device 8 through ports 81 and 82 can be the third tier number. Access device 8 can determine ports 81 and 82 as the second candidate port. Access device 8 can determine port 82 as the third candidate port according to preset rules. In summary, access device 8 can determine the third candidate port (port 82) as the target port. Figure 6 (B in the diagram can represent the target port). After access device 8 sets port 81 to an available state, port 53 on aggregation device 5 can automatically be switched to an available state.
