Abstract
Description
Technical Field
[0001] This application relates to the field of switch port status, and in particular to a port status processing method, device and medium for avoiding link sway. Background Technology
[0002] Based on Errdisable (false dead state) link oscillation detection technology, the industry primarily uses Errdisable to protect systems by disabling abnormal interfaces. Normally, if a switch is operating normally, its port entry will show as enabled. However, if the switch software detects errors on a port, the port will be randomly shut down. In other words, when the switch's operating system detects an error event on a port, the switch will automatically shut it down. When a port is in the Errdisable state, no traffic will be forwarded from that port, and no inbound traffic will be received. This can be seen using commands like `show interfaces`. The two functions of Errdisable are: 1. Informing the administrator of port status errors. 2. Preventing irreversible damage to the entire system due to a single port's error.
[0003] With the existing Errdisable module for detecting link sway, for example, if an interface is configured to detect 5 link sway events within 10 seconds, the Errdisable module will set the interface to the Errdisable state to prevent frequent up / down events and protect the network. However, if a fiber is slowly inserted under this configuration, the interface will also receive a large number of up / down events in a short period of time, causing the port to be set to the Errdisable state, resulting in unnecessary interface protection and making it difficult to achieve the expected interface state. Summary of the Invention
[0004] This application provides a port status processing method, device, and medium for avoiding link sway, which solves the following technical problem: In the case of existing link sway detection and Errdisable, configuring the interface when slowly inserting optical fiber can easily cause unnecessary interface protection, making it difficult to achieve the expected interface status and hindering the normal connectivity of the network.
[0005] The embodiments of this application adopt the following technical solutions:
[0006] On one hand, embodiments of this application provide a port state processing method for avoiding link oscillation, including: identifying the line transmission state of the network interface of a switch to obtain a link oscillation state based on the network interface; continuously detecting port events corresponding to the link oscillation state to obtain network link determination result information; wherein the network link determination result information includes: normal transmission link oscillation and abnormal transmission link oscillation; if the network link determination result information is abnormal link oscillation, then performing a timing judgment on the port events based on a counting mechanism to obtain timing result information; based on the timing result information, performing a module judgment on the port events for a "fake dead" state to obtain network fault information, so as to determine whether the switch is connected; wherein the network fault information includes: necessary network faults and unnecessary network faults.
[0007] This application embodiment classifies and identifies Errdisable (false dead state) link oscillations on the network interfaces of the switch, effectively handling the state of ports in error states. This ensures that when a large number of port up / down events are triggered during the slow insertion of optical fibers, the configured interface will no longer be set to the Errdisable state, thus saving users the effort to resolve error states. Furthermore, before the Errdisable module processes port events, a functional module for judging abnormal port event states is added. When unnecessary link oscillation information is received, the normal network communication ports are guaranteed, maintaining the stability and robustness of the network topology, eliminating unnecessary interface protection, and more efficiently protecting the normal network connectivity.
[0008] In one feasible implementation, the network interface of the switch is subjected to line transmission status identification to obtain the link oscillation status based on the network interface. Specifically, this includes: using the switch's link-flap detection technology to perform continuous transmission detection on the line transmission status of the data flow in the network interface to obtain continuous data transmission information; wherein, the continuous data transmission information includes: irregular intermittent transmission information, regular intermittent transmission information, and continuous transmission information; based on the continuous data transmission information, the link oscillation status of the network interface is determined.
[0009] In one feasible implementation, before continuously detecting the port events corresponding to the link oscillation state to obtain network link determination result information, the method further includes: identifying and extracting irregular intermittent transmission information and regular intermittent transmission information in the link oscillation state; performing event reporting processing on the port events corresponding to the irregular intermittent transmission information and the port events corresponding to the regular intermittent transmission information to obtain reported port events; wherein, the port events are port up / down events.
[0010] In one feasible implementation, continuous detection of port events corresponding to the link oscillation state is performed to obtain network link determination result information. Specifically, this includes: based on the triggered reported port events, identifying the relevant settings of the link oscillation in the port events corresponding to the link oscillation state, and determining the port up / down events that can be restored; based on the repeated continuity of the determined port up / down events, detecting and judging the existence of link oscillation fault in the reported port events, and obtaining the network link determination result information.
[0011] In one feasible implementation, if the network link determination result information is abnormal link oscillation, then the port events are subject to a timing judgment based on a counting mechanism to obtain timing result information. Specifically, this includes: judging the continuity of time points and event response counts for the port events corresponding to the abnormal link oscillation according to a preset timer and a counting mechanism; if the time point is greater than a first preset time point and each time point has a corresponding event response, then the port events corresponding to the abnormal link oscillation are determined as timing passed information; if the time point is less than or equal to the first preset time point or each time point has a non-one-to-one event response, then the port events corresponding to the abnormal link oscillation are determined as timing failed information; wherein, the timing result information consists of the timing passed information and the timing failed information.
[0012] In one feasible implementation, after determining the port event corresponding to the abnormal link oscillation as timing failure information, the specific steps include: if the port event corresponding to the abnormal link oscillation is determined to be timing failure information, then determining whether there is a corresponding event response at each time point; if there is a one-to-one corresponding time response at each time point, then the time point is incremented, and the continuity of the time point and the number of event responses is determined for the port event after the time point is incremented, and this process is repeated until the time point is greater than a first preset time point and each time point has a one-to-one corresponding event response, thus obtaining the timing success information.
[0013] In one feasible implementation, based on the timing result information, a module for determining the "dead state" of the port event is used to obtain network fault information, thereby determining whether the network is connected to the switch. Specifically, this includes: based on the timing pass information in the timing result information and according to the Errdisable module, a module triggering determination for the "dead state" of the port event is performed; wherein, the "dead state" is a mechanism for closing abnormal network interfaces based on the Errdisable module; if the port event has triggered the port setting corresponding to the "dead state," then the network port of the port event is determined to be in an Errdisable "dead state," thereby denying the corresponding network connection in the switch; if the port event has not triggered the port setting corresponding to the "dead state," then the network port of the port event is not subject to Errdisable "dead state" control, thereby allowing the corresponding network connection in the switch to be maintained.
[0014] In one feasible implementation, the port event has triggered the port setting corresponding to the dead state, specifically including: if the port event based on the timed information triggers a corresponding number of port up / down events within a preset time period, then the port event is processed to set the port.
[0015] Secondly, embodiments of this application also provide a port state processing device for avoiding link sway, the device comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor to enable the at least one processor to execute a port state processing method for avoiding link sway as described in any of the above embodiments.
[0016] Thirdly, embodiments of this application also provide a non-volatile computer storage medium, characterized in that the storage medium is a non-volatile computer-readable storage medium, the non-volatile computer-readable storage medium stores at least one program, each program including instructions, and when the instructions are executed by a terminal, the terminal executes a port state processing method for avoiding link sway as described in any of the above embodiments.
[0017] This application provides a port status processing method, device, and medium for avoiding link oscillations. By classifying and identifying Errdisable (false dead state) link oscillations on the network interfaces of the switch, it can effectively process the status of ports in error states. This ensures that when a configuration interface is slowly inserted into the fiber optic cable, triggering a large number of port up / down events, it will no longer be set to the Errdisable state, thus saving users the effort to resolve error states. Furthermore, before the Errdisable module processes port events, a functional module for judging abnormal port event states is added. When unnecessary link oscillation information is received, it ensures normal network communication ports, maintains the stability and robustness of the network topology, eliminates unnecessary interface protection, and more efficiently protects the normal network connectivity.

[0022] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.
[0023] This application provides a port state handling method to avoid link sway, such as... Figure 1 As shown, the port state handling method to avoid link sway specifically includes steps S101-S104:
[0024] It's important to note that, under normal circumstances, the existing link-flap detection in the switch is sufficient to handle ports in error states. This involves changing the state of previously up ports to Errdisable to prevent a large number of up / down events from affecting other functional modules and causing system failures. However, when fiber optic modules are slowly inserted into the interface, glitches may be generated, resulting in intermittent up / down signals. Without intervention, these signals cannot recover automatically, causing the port to repeatedly receive a large number of up / down events. This puts the desired port into an Errdisable state, creating a false dead state. In this case, we need to manually handle the Errdisable state, leading to unnecessary state changes and increased workload.
[0025] S101. Identify the line transmission status of the network interface of the switch to obtain the link oscillation status based on the network interface.
[0026] Specifically, the link-flap detection technology of the switch is used to detect the continuous transmission status of data flow in the network interface, obtaining continuous data transmission information. This continuous data transmission information includes: irregular intermittent transmission information, regularly intermittent transmission information, and continuous transmission information. Then, based on this continuous data transmission information, the link oscillation state of the relevant network interface is determined.
[0027] In one embodiment, Figure 2 This application provides a schematic diagram of the workflow of a port status-based judgment module, as shown in the embodiments below. Figure 2 As shown, before the port up / down event is reported, the network interface in the switch used for network data transmission is tested for whether the data is transmitted continuously, and the irregular intermittent transmission information, the regular intermittent transmission information, and the continuous transmission information are determined.
[0028] S102. Continuously detect the port events corresponding to the link oscillation state to obtain network link determination result information. This network link determination result information includes: normal transmission link oscillation and abnormal transmission link oscillation.
[0029] Specifically, the system identifies and extracts both irregular and regular intermittent transmission information from the link oscillation state. The port events corresponding to the irregular and regular intermittent transmission information are then processed for event reporting to obtain reported port events. These port events are port up / down events.
[0030] Furthermore, based on the triggered reported port events, the port events corresponding to the link oscillation state are identified to determine the port up / down events that can be restored.
[0031] Furthermore, based on the determined recurrence of port up / down events, the existence of link oscillation faults is detected and judged for the reported port events, and network link determination results are obtained.
[0032] As a possible implementation method, such as Figure 2 As shown, by identifying and extracting irregular and regular intermittent transmission information in the link oscillation state, port events corresponding to the link oscillation state that may have necessary or unnecessary faults are reported, which is beneficial for subsequent network fault determination related to the Errdisable state.
[0033] S103. If the network link determination result is abnormal link oscillation, then the port event is judged at regular intervals by the relevant counting mechanism to obtain the timing result information.
[0034] Specifically, based on a preset timer and a counting mechanism, the continuity of the port events corresponding to abnormal link oscillations is determined by the relevant time points and the number of event responses.
[0035] Furthermore, if the time point is greater than the first preset time point and there is a one-to-one corresponding event response for each time point, then the port event corresponding to the abnormal link oscillation is determined as timing pass information. If the time point is less than or equal to the first preset time point or there is a non-one-to-one corresponding event response for each time point, then the port event corresponding to the abnormal link oscillation is determined as timing fail information. The timing result information consists of timing pass information and timing fail information.
[0036] Specifically, after identifying the port event corresponding to abnormal link oscillation as a timing failure message, the process includes: if the port event corresponding to abnormal link oscillation is identified as a timing failure message, then it is determined whether there is a corresponding event response at each time point. If there is a one-to-one corresponding time response at each time point, the time point is incremented, and the continuity of the time point and the number of event responses is judged for the port event after the incremented time point. This process is repeated until the time point is greater than a first preset time point and each time point has a one-to-one corresponding event response, thus obtaining a timing success message.
[0037] In one embodiment, such as Figure 2As shown, a three-second timer and a counting mechanism are used to check for up / down events on the port every second within those three seconds. If up / down events occur for three consecutive seconds, we can consider that the network line has failed and allow it to proceed to the normal Errdisable module for processing, setting the corresponding port to the Errdisable state. For up / down events where the count is less than or equal to 3 seconds, the count is incremented for each matching up / down event, and this process is repeated until the time interval exceeds 3 seconds and each time interval has a corresponding event response, thus obtaining the timing pass information.
[0038] S104. Based on the timing results, the module judges the port event in a "fake dead" state to obtain network fault information, thereby determining whether the switch is connected. The network fault information includes both necessary and unnecessary network faults.
[0039] Specifically, based on the timing pass information in the timing result information, and according to the Errdisable module, the module triggers a judgment on the port event in a "fake dead" state. The "fake dead" state is a mechanism for closing abnormal network interfaces based on the Errdisable module.
[0040] Furthermore, if a port event has triggered the port setting corresponding to the suspended state—that is, if a port event based on timed information triggers the corresponding number of port up / down events within a preset time period—then the port event will be set, and the network port of the port event will be determined to be in an Errdisable suspended state, so that the network in the switch will be denied the corresponding connection. If a port event has not triggered the port setting corresponding to the suspended state, then the network port of the port event will not be controlled to be in an Errdisable suspended state, so that the network in the switch will be allowed to connect accordingly.
[0041] In one embodiment, such as Figure 2 As shown, if a port event has triggered the port setting corresponding to the dead state, that is, if an up / down event occurs within 1 to 2 seconds based on the port event under the timed pass information, it will be considered an unnecessary network failure, and thus the Errdisable module will not be triggered to set the port to the Errdisable dead state, thereby ensuring normal network connectivity. Otherwise, the network port of the port event will be determined to be in the Errdisable dead state, so as to refuse the corresponding network connectivity processing in the switch.
[0042] In addition, embodiments of this application also provide a port state processing device to avoid link sway, such as... Figure 3 As shown, the port status processing device 300 for avoiding link sway specifically includes:
[0043] At least one processor 301. And a memory 302 communicatively connected to the at least one processor 301; wherein the memory 302 stores instructions executable by the at least one processor 301, enabling the at least one processor 301 to execute:
[0044] The network interface of the switch is used to identify the line transmission status, and the link oscillation status based on the network interface is obtained.
[0045] The port events corresponding to the link oscillation state are continuously detected to obtain network link determination results; the network link determination results include: normal transmission link oscillation and abnormal transmission link oscillation.
[0046] If the network link determination result is abnormal link oscillation, then the port event is timed and judged according to the relevant counting mechanism to obtain the timing result information;
[0047] Based on the timing results, the module judges the port event in a dead state to obtain network fault information, so as to determine whether the network is connected to the switch; the network fault information includes necessary network faults and unnecessary network faults.
[0048] This application provides a port status handling method, device, and medium to avoid link oscillations. By classifying and identifying Errdisable (false dead state) link oscillations on the network interfaces of the switch, it can effectively handle the status of ports in error states. This ensures that when a configuration interface is slowly inserted into the fiber optic cable, triggering a large number of port up / down events, it will no longer be placed in the Errdisable state, thus saving users the effort to resolve error states. Furthermore, before the Errdisable module processes port events, a functional module for judging abnormal port event states is added. When unnecessary link oscillation information is received, it ensures normal network communication ports, maintains the stability and robustness of the network topology, eliminates unnecessary interface protection, and more efficiently protects the normal network connectivity.
