Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a stacking system detection system, a method, a device and a computer readable storage medium, which are used for simplifying the deployment of a detection link.
Referring to fig. 1, a stacking system detection system provided in an embodiment of the present invention includes at least two stacking switches, and specifically includes:
and the switch controller 101 is in communication connection with each stack switch 102, and is configured to receive a detection message sent by a main stack switch in the stack system 103, and determine whether a plurality of main stack switches appear in the stack system according to the detection message.
The switch Controller 101 is also a Wireless Access Point Controller (Wireless Access Point Controller), and the Controller is used for centrally controlling the switches in the networking structure of the stacking system, and is responsible for managing all switches in the network, such as issuing configuration to the switches, modifying related configuration parameters, accessing security control, and displaying the states of the switch devices. In the scheme, other devices do not need to be added to change the networking structure, but the exchange controller 101 in the original networking structure is used for detecting the multiple master devices in the stacking system.
The stack system 103 includes at least two stack switches 102, and the stack switches 102 are connected by a dedicated stack interface to form a stack link. In this scenario, the detection links do not need to be formed between the stack switches 102, i.e., in this scenario, the detection links do not need to be connected between the stack switches 102 and the stack switches 102, but all the stack switches 102 are connected to the switch controller 101 in the current networking architecture.
Each stack switch 102 is configured in advance, and when the stack switch becomes a master stack switch, a detection message is sent to the switch controller, and the switch controller 103 can determine whether a plurality of master stack switches sending the detection message are present in the current stack system according to the detection message.
In one embodiment, the detection message includes a unique identifier of the primary stack switch and a unique identifier of the stack system.
The unique identifier of the master stack switch may be a Media Access Control Address (MAC Address) of the master stack switch, and the unique identifier of the stack system 103 may be a unique ID previously allocated to the stack system. Even if stack splitting occurs, the original stacking system is split into a plurality of stacking systems, and the unique ID of the original stacking system still retains the unique ID of the original stacking system, so that the switch controller 101 can determine whether a plurality of primary stack switches are present in the stacking system 103 according to the unique identifier of the stacking system 101 and the unique identifier of the primary stack switch, that is, when the unique identifier of the same stacking system corresponds to a plurality of different primary stack switches, it indicates that a plurality of primary stack switches are present in the stacking system.
For example, the unique identifier of the stack system 103 is stack identifier 1, and there are originally 2 stack switches under the system, and the identifiers are sw1 and sw2, respectively, where sw1 is the master switch. The detection message sent by the sw1 to the switch controller 101 includes "stack identifier 1, sw 1"; the stack system 103 is subjected to stack splitting, the two stack switches are split into independent systems respectively and become main stack switches in the independent systems, and each split system retains the configuration of the original system due to the principle of stack splitting, so the stack identifiers of the two split systems are still the stack identifier 1, at this time, the sw2 also becomes the main stack switch of the split stack system, so the sw2 also sends a detection message "stack identifier 1, sw 2" to the switch controller 101, the switch controller 101 receives two detection messages at this time, and the two detection messages both correspond to the same stack system but are not the same stack switch, and the switch controller 101 can determine that two main stack switches appear in the stack system corresponding to the stack identifier 1.
In a specific embodiment, the detection message includes a unique identifier of the primary stack switch and a unique identifier of the stack system;
the switch controller 101 determines the unique identifier of the primary stack switch and the unique identifier of the stack system 103 by using the detection packet, and determines whether the number of the unique identifiers of the primary stack switch currently corresponding to the unique identifier of the stack system 103 is greater than 1.
The unique identifier of the master stack switch may be a Media Access Control Address (MAC Address) of the master stack switch, and the unique identifier of the stack system 103 may be a unique ID previously allocated to the stack system 103. Even if stack splitting occurs, the original stacking system is split into a plurality of stacking systems, and the unique ID of the original stacking system still retains the unique ID of the original stacking system, so that the switch controller 101 can determine whether a plurality of master stacking switches are present in the stacking system 103 according to the unique identifier of the stacking system 103 and the unique identifier of the master stacking switch, that is, when the unique identifier of the same stacking system 103 corresponds to more than or equal to 2 different master stacking switches, it indicates that there are a plurality of master stacking switches in the stacking system 103.
For example, the unique identifier of the stack system 103 is stack identifier 1, and there are originally 2 stack switches under the system, and the identifiers are sw1 and sw2, respectively, where sw1 is the master switch. The detection message sent by the sw1 to the switch controller 101 includes "stack identifier 1, sw 1"; the stack system 103 is subjected to stack splitting, the two stack switches 102 are respectively split into independent systems, and due to the principle of stack splitting, each split system retains the configuration of the original system, so the stack identifiers of the two split systems are still stack identifiers 1, at this time, the sw2 also becomes the master stack switch of the split stack system, so the sw2 also sends detection messages "stack identifier 1, sw 2" to the switch controller 101, the switch controller 101 receives the two detection messages at this time, and the two detection messages both correspond to the same stack system but are not the same stack switch, and the switch controller 101 can determine that two master stack switches appear in the stack system corresponding to the stack identifier 1.
Therefore, in the stacking system detection system provided in the embodiment of the present application, each stack switch 102 in the stacking system 103 is connected to an existing switch controller 101 in an original networking structure, and when the stack switch 102 becomes a master stack switch, a detection message is sent to the switch controller 101, and the switch controller 101 may determine whether a plurality of master switches exist in the stacking system 103 according to the number of the master stack switches that send the detection message. Therefore, in the scheme, the original networking structure does not need to be changed, new equipment does not need to be added, a detection link does not need to be established between every two stacking switches, detection can be completed only by using the switch controller 101 in the original networking structure, and the deployment of the detection link is simplified.
A stacking system detection method provided in the embodiments of the present application is introduced below, and the following description of a stacking system detection method and any of the embodiments described above may be referred to with each other.
Referring to fig. 2, a method for detecting a stacking system provided in the embodiment of the present application specifically includes:
s201, receiving a detection message sent by a main stack switch in the stack system.
The switch controller is connected to each stack switch in the stack system, and a specific networking structure is described in detail in the above embodiment, and specific contents may refer to the above embodiment, which is not described in detail in this embodiment.
The switch controller receives a detection message sent by a main stack switch in the stack system. The detection message can be sent only by the main stack switch, and the specific rule for sending may be that when the stack switch detects that it becomes the main stack switch, the detection message is sent to the switch controller immediately, or all the devices that have become the main stack switch send the detection message once at every preset time interval as the switch controller.
If the second scheme is adopted, in order to save the storage space of the switch controller, when a detection message sent by a main stack switch is received, whether a history detection message sent by the main stack switch is stored or not is judged, and if the history detection message is stored, the history detection message is deleted.
S202, determining whether a plurality of main stack switches appear in the stack system by using the detection message.
Specifically, the switch controller may determine whether a plurality of primary stack switches sending the detection messages are present in the current stack system according to the detection messages, that is, when the detection messages sent by the plurality of stack switches are received, it may determine that a plurality of primary stack switches are present in the current stack system.
In a specific embodiment, the switch controller and the stacking system belong to the same two-layer network; or, the switch controller with the stack system belongs to the same three-layer network, every the stack switch with pass through between the switch controller router communication connection.
Referring to fig. 3, the switch controller and the stacking system belong to the same two-layer network, the two-layer network only has a core layer and an access layer, and the network structure mode is simple and convenient to operate. When the switch controller and the stacking system belong to a two-layer network, each stacking switch can be directly connected with the switch controller, a router is not required to be used for forwarding, and the networking structure is simple.
It should be noted that, because the stack switches are also switches and have a data forwarding function, the stack switches can also forward the detection messages of other stack switches to the switch controller, and it is not necessary that each stack switch is directly connected to the switch controller.
Referring to fig. 4, the switch controller belongs to the same three-layer network as the stacking system. Unlike a two-tier network, a three-tier network structure can be populated with large networks. Generally, when the networking structure of the switch controller 101 and the stack system 103 cannot be implemented by a two-layer network structure, for example, if the switch controller 101 is too far away from the stack system 103, a three-layer network is adopted, and at this time, there are routers in the networking structure, and the routers forward data transmitted between the switch controller 101 and switches controlled by the router. In this embodiment, if the network structure of the stack system detection system is a three-layer network, that is, each stack switch 102 is communicatively connected to the switch controller 101 through the router 104, the detection packet may also be transmitted through the router at this time.
In the three-layer network architecture, each stack switch 102 is connected to the switch controller 101 using its own IP address, thereby enabling communication between the stack switch 102 and the switch controller 101.
In a specific embodiment, the determining whether a plurality of primary stack switches are present in the stack system using the detection message includes:
determining the unique identifier of the main stack switch and the unique identifier of the stack system by using the detection message;
and judging whether the number of the unique identifiers of the main stacking switch currently corresponding to the unique identifier of the stacking system is more than 1.
The unique identifier of the master stack switch may be a MAC address of the master stack switch, and the unique identifier of the stack system may be a unique ID previously assigned to the stack system. Even if stack splitting occurs, the original stacking system is split into a plurality of stacking systems, and the unique ID of the original stacking system still retains the unique ID of the original stacking system, so that the switch controller can determine whether a plurality of master stacking switches are present in the stacking system according to the unique identifier of the stacking system and the unique identifier of the master stacking switch, that is, when the unique identifier of the same stacking system corresponds to more than or equal to 2 different master stacking switches, it indicates that a plurality of master stacking switches are present in the stacking system.
For example, the unique identifier of the stack system is stack identifier 1, and there are originally 2 stack switches under the system, and the identifiers are sw1 and sw2, respectively, where sw1 is the master switch. The detection message sent by the sw1 to the switch controller includes "stack identifier 1, sw 1"; the stacking system is subjected to stacking splitting, two stacking switches are split into independent systems respectively, and each split system retains the configuration of the original system due to the principle of stacking splitting, so that the stacking identifiers of the two split systems are still stacking identifiers 1, at this time, the sw2 also becomes the main stacking switch of the split stacking system, so that the sw2 also sends detection messages 'stacking identifier 1, sw 2' to the switch controller, the switch controller receives the two detection messages at this time, the two detection messages correspond to the same stacking system, but not the same stacking switch, and the switch controller can determine that the two main stacking switches appear in the stacking system corresponding to the stacking identifier 1.
Therefore, according to the detection method for the stacking system provided by the embodiment of the application, each stacking switch in the stacking system is connected with the switch controller, and the switch controller receives the detection message sent by the device serving as the main stacking switch in the stacking system, that is, whether a plurality of main switches exist in the stacking system can be determined according to the number of the main stacking switches sending the detection message. Because the switch controller is arranged in the original networking structure, the original networking structure does not need to be changed, new equipment does not need to be added, and meanwhile, the detection link can be established only by connecting the stacking switches with the switch controller, so that the detection link does not need to be established between every two stacking switches, the detection can be completed only by using the stacking switches in the original networking structure, and the arrangement of the detection link is simplified.
A specific method for detecting a stacking system provided in the embodiments of the present application is described below, and a specific method for detecting a stacking system described below may be mutually referred to any of the embodiments described above.
Referring to fig. 5, a specific stacking system detection method provided in the embodiment of the present application specifically includes:
s301, receiving a detection message sent by a main stack switch in the stack system.
S302, determining whether a plurality of main stack switches appear in the stack system by using the detection message.
S303, when a plurality of main stack switches appear in the stack system, determining a target main stack switch in the plurality of main stack switches by using a preset strategy, and sending a command of suspending a control function to a non-target main stack switch in the plurality of main stack switches.
It should be noted that, in order to cause a network failure due to a plurality of stack systems with the same configuration in a network, when two primary stack switches corresponding to one stack system are detected, the network state of one primary stack switch of one stack system needs to be restored in time.
The conventional means for solving the above problems is to configure the same configuration policy in each stack switch, and all stack switches execute their own stored configuration policies, and the configuration policy can implement that one master stack switch is still in a working state with a control function, and other master stack switches suspend the control function, so that only one master switch corresponding to one stack system is provided in the entire network, thereby ensuring that there is no stack system with the same configuration in the network environment.
However, this method requires configuring each stack switch, so that each stack switch has the same configuration policy, which is very inconvenient.
In this scheme, the preset policy is stored and executed by the switch controller. The switch controller determines a target master stack switch capable of continuing to operate from all current master stack switches by using a preset strategy, and sends a command of a pause control function to other non-target master stack switches, so that only one master stack switch of the stack system is available in the current network.
In one specific embodiment, the determining a target primary stack switch among the plurality of primary stack switches using a predetermined policy includes:
determining a target primary stack switch with the highest priority by using the preset priority of each primary stack switch; wherein the priority is a priority determined based on performance data of each of the primary stack switches.
In the scheme, the priority is set for each stack switch according to the performance data of each stack switch in the stack system, and the higher the priority is, the better the performance is. In the switch controller, the preset policy is set according to the priority, and the target primary stacking system is the highest priority of all the primary stacking systems, that is, the target primary stacking system has the best performance of all the primary stacking systems.
The switch controller is used for managing the working strategies of all the stacking switches in a centralized manner, so that the configuration in each stacking switch can be avoided, manpower and material resources are saved, meanwhile, only one preset strategy in the switch controller needs to be modified for modifying the strategy, and each stacking switch does not need to be modified, so that the strategy can be modified conveniently.

S402, determining whether a plurality of main stack switches appear in the stack system by using the detection message.
S403, when a plurality of main stack switches appear in the stack system, receiving the information of the target main stack switch, and sending a command of suspending the control function to a non-target main stack switch in the plurality of main stack switches.
In this scheme, the switch controller may directly receive the target master stack switch information sent by the user, and determine the target master stack switch to continue as the master stack switch and the master stack switch that needs to suspend the control function according to the target master stack switch information sent by the user. Therefore, the user setting can be realized immediately, and the target main stack exchanger is determined according to the user setting.
