Illustratively, in conjunction with fig. 1, the network cluster may include: a core network and two switches (switch 1 and switch 2) respectively connected with the core network. The switch 1 is connected with a client resource pool A, and the switch 2 is connected with a client resource pool B.

Referring to fig. 2, a schematic flow chart of an alternative method for detecting network configuration according to an embodiment of the present invention will be described with reference to the steps shown in fig. 2.

S101, obtaining configuration information of the virtual local area network, and forming a plurality of first detection messages of the nodes to be detected, wherein the nodes to be detected respectively correspond to the virtual local area networks to which the nodes belong, based on the configuration information of the virtual local area network.

In the embodiment of the invention, a main control node acquires Virtual Local Area Network (VLAN) configuration information, and forms a plurality of first detection messages of nodes to be detected, which respectively correspond to the respective VLAN to which the nodes belong, based on the VLAN configuration information.

In the embodiment of the invention, after the master control node is started, the master control node detects that the local equipment is the master control node, and then the master control node obtains the configuration information of the virtual local area network from local scanning. The master control node forms a plurality of first detection messages of the to-be-detected nodes corresponding to the virtual local area networks of the to-be-detected nodes respectively based on the configuration information of the virtual local area networks. The master control node can scan locally at preset time intervals to acquire the configuration information of the virtual local area network. At least one virtual local area network to which each node to be tested belongs can be provided.

In the embodiment of the present invention, the master control node and the node to be tested may be any switch or server in the network cluster. After each node in the network cluster is started, the information of the main control node is acquired from the local and matched with the information of the local equipment. And determining the attribute of each node through matching by each node, if the local equipment information of one node is matched with the main control node information, determining that the node is the main control node, and if the local equipment information of another node is not matched with the main control node information, determining that the other node is the node to be tested. The network cluster comprises a main control node and a plurality of nodes to be tested.

For example, the virtual local area network to which any node to be tested belongs may include: VLAN1 and VLAN2. The main control node can construct a first detection message of the VLAN1 corresponding to the node to be detected according to the configuration information of the virtual local area network, and simultaneously construct a first detection message of the VLAN2 corresponding to the node to be detected according to the configuration information of the virtual local area network.

In the embodiment of the present invention, the virtual local area network configuration information includes: the system comprises local tunnel network address information, VLAN lists put through by all virtual local area networks, tunnel port names of master control nodes and tunnel network address information of a plurality of nodes to be tested. Each virtual local area network can correspondingly put through at least one node to be tested, and the nodes to be tested corresponding to the virtual local area networks can be overlapped. The master control node may form, based on the virtual local area network configuration information, first detection packets of the virtual local area networks to which the plurality of nodes to be detected respectively belong, and the master control node may form, based on the virtual local area network configuration information, second detection packets of the virtual local area networks to which the plurality of nodes to be detected respectively belong. The first detection message does not include identification information of a virtual local area network to which the corresponding node to be detected belongs, and the second detection message includes identification information of a virtual local area network to which the corresponding node to be detected belongs.

Both the first detection Message and the second detection Message may be Loop Back Message (LBM).

In the embodiment of the invention, the main control node obtains the main control node information from the local after being started, and the local equipment information and the main control node information are detected to obtain the detection result matched with each other, so that the local equipment is determined to be the main control node.

S102, sending the first detection messages to a plurality of nodes to be detected at intervals of a certain length, and corresponding to the first detection messages of the virtual local area networks to which the nodes to be detected belong.

In the embodiment of the invention, the master control node respectively sends the first detection messages corresponding to the virtual local area networks to which the master control node respectively belongs to a plurality of nodes to be detected at intervals of a fixed time length.

In the embodiment of the invention, the master control node respectively sends the first detection messages corresponding to the virtual local area networks to which the master control node respectively belongs to a plurality of nodes to be detected at intervals of a fixed time length. And each node to be detected forms a corresponding first response message after receiving the first detection message and feeds the first response message back to the main control node. And the main control node matches the information in the first detection message and the first response message. And if the corresponding information is completely matched, the main control node determines that the link of the node to be detected corresponding to the first detection message is normal, and the main control node constructs and sends a second detection message of the node to be detected. And if any information is not correspondingly matched, the main control node determines the detection result of the link abnormity of the node to be detected corresponding to the first detection message, and the main control node cannot send a second detection message of the node to be detected.

In the embodiment of the invention, the main control node sends the corresponding first detection message to each node to be detected, and if any node to be detected does not feed back the corresponding response message, the main control node does not send a subsequent second detection message to the node to be detected. And the main control node determines the detection result of the link fault of the node to be detected.

S103, determining a middle node to be tested which is communicated with a physical link in the nodes to be tested based on the received response messages fed back by the nodes to be tested.

In the embodiment of the invention, the master control node determines the middle node to be tested which is communicated with the physical link in the nodes to be tested based on receiving the response messages fed back by the nodes to be tested.

In the embodiment of the invention, after each node to be detected receives the first detection message which is sent by the main control node and corresponds to the virtual local area network, a response message corresponding to the first detection message is formed. Each node to be detected can feed back a response message corresponding to the received first detection message to the master control node. And the main control node matches the information in the first detection message and the first response message. If all the corresponding information is matched, the main control node determines that the link of the node to be detected corresponding to the first detection message is normal, and further determines that the node to be detected corresponding to the first response message is the middle node to be detected.

For example, the virtual local area network to which any node to be tested belongs may include: VLAN1 and VLAN2. The main control node may send first detection packets corresponding to VLAN1 and VLAN2, respectively, to the node to be detected. The node to be detected forms response messages respectively corresponding to the first detection messages of the VLAN1 and the VLAN2, and the response messages are fed back to the main control node.

The response message may include: loop Back detection Reply (LBR).

Illustratively, in conjunction with fig. 3, the network cluster includes: nodes PE1, PE2, PE3 and PE4. After each node is started, each node judges through the acquired master control node information, and determines that PE1 is a master control node and PE2, PE3 and PE4 are nodes to be detected. The main control node PE1 constructs first detection messages corresponding to the nodes to be detected respectively. The main control node PE1 sends corresponding first detection messages to the PE2, the PE3 and the PE4 respectively. The nodes PE2 and PE3 to be tested feed back the corresponding response messages to the main control node PE1, and PE4 does not feed back the corresponding response messages to the main control node PE1, then the main control node PE1 will continue to send the second message to be tested to the nodes PE2 and PE3 to be tested, and the main control node PE1 will not send the corresponding second message to be tested to the node PE4 to be tested.

S104, constructing a second detection message based on the middle first detection message corresponding to the middle node to be detected; the second detection message is different from the middle first detection message in that the second detection message contains identification information of a virtual local area network to which the middle node to be detected belongs.

In the embodiment of the invention, the main control node matches the first detection message of each node to be detected with the source and destination tunnel network address information and the corresponding random serial number in the corresponding response message, and if all the information are matched, the main control node determines the normal detection result of the link of the node to be detected. The main control node adds the identification information of the virtual local area network to the first detection message of the middle to-be-detected contact point with a normal link to form a corresponding second detection message.

And S105, determining a configuration detection result of the virtual local area network to which the intermediate node to be detected belongs based on the second detection message.

In the embodiment of the invention, the main control node determines the configuration detection result of the virtual local area network to which the middle node to be detected belongs based on the second detection message.

And the main control node matches the second detection message with the source and destination tunnel network address information, the local area network identification information and the corresponding random serial number in the corresponding second response message, and if all the information are matched, the main control node determines that the virtual local area network to which the node to be detected belongs is configured with a normal detection result. And if any information is not correspondingly matched, the main control node determines the detection result of the configuration error of the virtual local area network to which the node to be detected belongs.

According to the scheme, the main control node sends the first detection message to the node to be detected at regular intervals, and when the link of the middle node to be detected is communicated, the second detection message corresponding to the virtual local area network to which the middle node to be detected belongs can be sent in time, so that the network configuration problem of the node to be detected can be detected quickly, and the timeliness of network link configuration detection is improved.

VLANs in a network cluster may include traffic VLANs and leased line VLANs. The server HCI201 may serve as a master node, and the server HCI201 sends an OAM (Operation, administration, and Management) LBM message to other nodes to be tested. The server HCI202 and the server HCI203 are used as nodes to be tested to start service monitoring OAM LBM messages.
