Description

Method and device for managing port configuration mode

This article claims the priority of the Chinese patent application CN201910440079.2 named "A method and device for managing port configuration mode" filed on May 24, 2019, the entire content of which is incorporated herein by reference.

Technical field

The embodiments herein relate to, but are not limited to, Ethernet technology, and in particular to a method and device for managing port configuration modes.

Background technique

In the process of interconnecting Ethernet devices, in addition to ensuring the normal physical connection, it is generally required that the port configuration modes of the two interconnected parties must be consistent, otherwise a malfunction may occur.

In practical applications, it often happens that after a docking device restarts due to some reasons (such as device power failure or active operation, etc.), the physical status of the device docking port is DOWN (hereinafter the device is referred to as the local device). This situation will cause the service and management carried on the port to be interrupted. After processing, it is often found that the cause of the failure is the inconsistent configuration modes of the two pairs. Therefore, in some cases, it is necessary to modify the port configuration modes of the two parties to keep the ports connected to the device consistent. However, the local device cannot modify the port configuration mode remotely due to the disconnection, which makes modification difficult.

In the network construction, because the docking equipment may belong to different operation and maintenance parties and cannot be monitored through a unified operation and maintenance platform, it is impossible to ensure that the port configuration mode of the docking equipment remains consistent, and it also leads to increased maintenance costs. During the long-term operation and maintenance of network equipment, situations such as device replacement and configuration modification may also cause the docking port configuration mode to be modified, which may result in inconsistent docking port configuration modes. In one embodiment, although a link may be established when the docking port configuration mode is inconsistent, when the network device has operations that change the behavior of the device such as software update, the docking port may not be able to establish a link.

Summary of the invention

In view of this, the embodiment of this document provides a method for managing port configuration mode, including: comparing the consistency of the local port configuration mode with the predicted counterpart port configuration mode; according to the physical state of the local port and the Consistency, set the local port configuration mode.

The embodiment of this document also provides an apparatus for managing port configuration mode, including: a comparing unit, configured to compare the consistency of the local port configuration mode with the predicted counterpart port configuration mode; and a setting unit, configured according to the local end The physical state of the port is consistent with the consistency, and the local port configuration mode is set.

Detailed ways

In order to make the purpose, technical solutions and advantages of this document clearer, the embodiments of this document will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments herein and the features in the embodiments can be combined with each other arbitrarily.

The steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than here.

In some cases, when network devices are connected, port negotiation is performed according to their respective port configuration modes. When the port mode negotiation at both ends depends on the respective port configuration. When the port mode (adaptive/mandatory) configuration on both ends is inconsistent, the port may not work normally (even if the port works normally, there are hidden dangers).

In addition, since the network docking device may be independently managed and maintained in terms of physical location and logical relationship, there are difficulties in the unified management and query of the above-mentioned port configuration at both ends, that is, it is difficult to handle problems when problems occur.

To this end, the embodiments herein propose the following technical solutions to address the above-mentioned problems.

The port configuration mode is inconsistent.

In one embodiment, when the physical state of the local port is DOWN and the consistency is consistent, after keeping the local port configuration mode unchanged, the method further includes: starting a counter N, and initializing N If it is 0, restart the local port and start the timer T4 to detect the physical status of the local port; if the physical status of the local port is UP, stop the operation on the local port; if The physical status of the local port is DOWN. After T4 expires, the local port is restarted again, and the physical status of the local port is detected, and N=N+1; when N reaches the threshold, stop the Operation of the local port.

In an embodiment, before comparing the consistency of the local port configuration mode with the predicted counterpart port configuration mode, the method further includes: detecting the feature code stream sent by the opposite port received by the local port; When the feature code stream value is /C/frame, predict that the opposite port configuration mode is adaptive; when the feature code stream value is /I/frame, predict that the opposite port configuration mode is mandatory ; When the detection is invalid, predict that the opposite port configuration mode is unknown.

In an embodiment, before detecting the feature code stream sent by the opposite port and received by the local port, the method further includes: starting a timer T2; before the timer T2 expires, the feature code stream When the value remains stable, predict the configuration mode of the opposite port according to the characteristic code stream value; when the characteristic code stream value is unstable, it indicates that the detection is invalid; after the timer T2 expires, restart the timer T2, Re-detect the feature code stream.

In one embodiment, in the T2, the number of times of detecting the feature code stream is greater than or equal to 3.

In an embodiment, before setting the local port configuration mode according to the physical state of the local port and the consistency, the method further includes: detecting the effective state of the local port; The effective state of the local port determines the physical state of the local port, including: when the effective state of the local port is UP, then determining that the physical state of the local port is UP, and when the local port’s physical state is UP, If the effective state is DOWN, it is determined that the physical state of the local port is DOWN.

In one embodiment, before detecting the effective state of the local port, the method further includes: starting a timer T1; before the timer T1 expires, when the effective state of the local port remains stable, then The effective state of the local port determines the physical state of the local port; when the effective state of the local port is unstable, the detection is invalid.

In an embodiment, in the T1, the number of times of detecting the valid state of the local port is greater than or equal to 3.

In an embodiment, the notification message or the alarm message carries the geographic location of the local port and/or the geographic location of the opposite port.

Fig. 2 is a schematic flow chart of a method for managing port configuration mode according to another embodiment of this document. As shown in Fig. 2, the method includes: step 201, detecting the physical state of the local port in real time; in an embodiment, The physical state of the local port can be determined by detecting the effective state of the local port. For example, the effective status of the port is UP or DOWN. When it is detected that the effective state of the local port is UP, the physical state of the port is determined to be UP, and when the effective state of the local port is detected to be DOWN, the physical state of the port is determined to be DOWN.

In an embodiment, the timer T1 can be started to detect the physical state of the local port at a certain frequency. Through the timer T1, it can also detect whether the physical state of the port is stable, so as to avoid misjudgment caused by the unstable physical state of the port due to certain factors. Before the timer T1 expires, if the physical state of the monitoring port remains stable, the judgment result is valid, otherwise the result in this cycle is invalid. For example, in T1, if the physical status of the detected port is always DOWN or UP, it means that the status remains stable. If the physical status of the detected port is DOWN once, and UP the other time, it means the status is unstable. After the T1 timer expires, restart the T1 timer to recheck the physical status of the port.

In an embodiment, the detection frequency value in T1, that is, the number of sampling detections, can be selected according to a certain strategy to ensure that the number of sampling detections is at least ≥3 in the T1 period.

Step 202: Detect in real time the feature code stream sent by the opposite port received by the local port, and predict the configuration mode of the opposite port based on the value of the feature code stream; in one embodiment, the local port can be detected by The feature code stream received by the Rx port is received, whether it is /C/ or /I/ frame, to predict the configuration mode of the opposite port. For example, the predicted effective state of the peer port configuration mode is adaptive or mandatory. When the detected feature code stream value is /C/frame, it is judged as adaptive; when the detected feature code stream is /I/frame and there is no /C/frame, it is judged that the port mode of the opposite end is mandatory.

In an embodiment, the timer T2 can be started to directly detect the feature code stream received by the Rx port at the physical layer. The timer T2 is used to detect whether the port receiving feature code stream is stable, so as to avoid misjudgment caused by the instability of the receiving feature due to certain factors. Before the timer T2 expires, monitor that the status of the characteristic value of the received code stream on the local port remains stable, and then predict the configuration mode of the opposite port according to the characteristic value of the code stream; otherwise, the detection in this period is invalid, and it is judged that the mode of the opposite port is unknown. For example, in T2, the detected code stream feature value is always /C/, it means that the code stream feature value remains stable, and the peer port configuration mode is judged to be adaptive; for example, if the detected code stream feature value once is / C/, the other time is /I/frame, etc., it means that the characteristic value of the code stream is unstable, the detection is invalid, and the prediction of the peer port mode is unknown. After the T2 timer expires, restart the T2 timer to recheck the physical status of the port.

In one embodiment, the value of the detection frequency within T2, that is, the number of sampling inspections, can be selected according to a certain strategy to ensure that the number of sampling inspections is at least ≥3 in the T2 period.

Step 203: Compare the consistency of the local port configuration mode with the predicted counterpart port configuration mode; and set the local port configuration mode according to the physical state of the local port and the consistency.

In an embodiment, the local physical port status is: UP or DOWN; the predicted peer port configuration mode is: unknown, adaptive, and mandatory; the local port configuration mode is: adaptive, mandatory.

When the physical status of the local port is UP or DOWN, the following contents are included.

1.1. When the physical status of the local port is UP, compare the consistency between the local port configuration mode and the predicted peer port configuration mode: 1) When the predicted peer port configuration mode is consistent with the local port configuration mode, keep this The current configuration mode of the end port remains unchanged; 2) When the predicted peer port configuration mode is unknown, keep the current configuration mode of the local port unchanged; 3) When the predicted peer port configuration mode is inconsistent with the local port configuration mode , Keep the current configuration mode of the local port unchanged, and turn to 2.1 for processing.

In one embodiment, both the predicted peer port configuration mode and the local port configuration mode can be displayed through the operation and maintenance interface.

1.2. When the physical status of the local port is DOWN, compare the consistency between the local port configuration mode and the predicted peer port configuration mode: 1) When the predicted peer port configuration mode is unknown, reverse modify the local port configuration Mode, and transfer to 2.2 processing; in one embodiment, the local port mode is reversed according to the current value (adaptive or mandatory) of the local port configuration mode. For example, if the local port configuration mode is currently adaptive, it is changed to mandatory , If it is currently mandatory, modify it to adaptive.

2) When the predicted peer port configuration mode is clear (adaptive or mandatory) and is inconsistent with the local port configuration mode, modify the local port configuration mode to the peer port configuration mode, and transfer to 2.2 processing; In the implementation manner, the local port configuration mode is modified according to the current value (adaptive or mandatory) of the predicted peer port configuration mode. For example, if the peer port configuration mode is currently adaptive, the local port configuration mode is modified to adaptive. The remote port configuration mode is currently mandatory, so modify the local port configuration mode to mandatory.

3) When the predicted peer port configuration mode is clear (adaptive or mandatory) and consistent with the local port configuration mode, keep the current local port configuration mode unchanged, and proceed to 2.3.

2.1. Start timer T3 to monitor the physical status of the local port, and provide notification or alarm messages based on the detection result: the physical status of the local port is: UP or DOWN; 1) If T3 expires, the physical status of the local port The status remains UP, and a notification message is generated (Notification 1: Used to notify that the configuration mode of the opposite port is inconsistent with the configuration mode of the local port); 2) If the physical state of the port jitters before T3 times out, an alarm message is generated (Alarm 1: Used to notify that the physical status of the local port is unstable and that the configuration mode of the opposite port is inconsistent with the configuration mode of the local port); 3) If the physical status of the local port changes to DOWN before T3 times out, then go to 1.2.

In one embodiment, when a notification or alarm message is provided, a log is also recorded. The log content includes the current configuration mode of the local port, whether the configuration mode is modified, if it is modified, the modification record and reason, etc.

2.2. Start timer T3, monitor the physical status of the local port, and provide notification or alarm messages based on the detection result: the physical status of the local port is: UP or DOWN; 1) If T3 expires, the physical status of the local port If the status remains DOWN, the local port mode will be reversed again, that is, the original configuration mode will be restored; and an alarm message will be generated (Alarm 2: Used to notify that the physical status of the local port is abnormal, as well as the configuration mode of the peer port and the local port The port configuration mode is inconsistent); 2) If the physical state of the local port is jittered before T3 times out, the local port mode will be reversed again to restore the original configuration mode; and an alarm message (alarm 1: used to notify the local The physical state of the end port is unstable, and the configuration mode of the peer port is inconsistent with the configuration mode of the local port); 3) If T3 times out and the physical state of the local port becomes UP, the current port configuration mode is not modified and a notification message is generated (Notice 2: Used to notify that the local port configuration mode has been modified, and the opposite port configuration mode is inconsistent with the local port configuration mode).

2.3. Start the counter N (N is initialized to 0), restart the local port, and start the timer T4 to detect the physical state of the port: 1) If the physical state of the port is UP, it ends, that is, the operation of the port is stopped; 2 ) If the physical status of the port is DOWN, after T4 expires, the port is restarted again, and the physical status of the port is detected, and N=N+1; when N reaches the threshold, the operation of the port is stopped.

In an embodiment, the threshold may be artificially set according to certain rules.

In one embodiment, a log is also recorded, and the log content includes but is not limited to port configuration/status, restart reason/number of times, etc.

In one embodiment, the notification messages or alarm messages in 2.1 and 2.2 above may be reported to the network management or other operation and maintenance platforms. The notification message or the alarm message may also carry information such as the physical location of the local/opposite port, which is convenient for operation and maintenance personnel to perform on-site operations.

The technical solution provided in this embodiment directly receives the code stream by detecting the port, judges the port configuration mode of the peer device according to the port mode characteristic code stream, and then according to the physical state of the local port, and the local port configuration mode and the opposite port configuration mode Compare and adjust the configuration mode of the local port; in this way, on the basis of the existing equipment negotiation standards, there is no need to make any changes to the docking device, which has good compatibility; in addition, for the port of the docking device in the prior art The configuration method relies on the negotiation between the two parties, and the local and opposite device ports need to be managed and maintained separately, which leads to problems such as the port mode negotiation relying on the configuration of the docking parties and low positioning efficiency. The solution of this embodiment uses timer detection and counter processing methods for port status and related fault processing to smoothly handle possible jitter in port docking negotiation. The configuration mode of the peer port is judged based on the port protocol interaction, and the judgment and processing are combined with the state of the local port and the configuration method. The solution is simple and flexible, and it is easy to deploy applications on a large scale.

FIG. 3 is a schematic flowchart of a method for managing port configuration modes according to another embodiment of this document.

In this embodiment, the local device is provided with n ports, and automatic detection and recovery of the port configuration mode need to be implemented for these n ports.

As shown in Figure 3, the method includes: step 301, the network device maintains a port status table; the format of the port status table is as follows: {port serial number 1, physical location 1, local port configuration mode 1, local port physical status 1. Predicted peer port configuration mode 1; port number 2, physical location 2, local port configuration mode 2, local port physical state 2, predicted peer port configuration mode 2;......; port number n , Physical location n, local port configuration mode n, local port physical state n, predicted peer port configuration mode n;} Or, it can be as shown in Table 1:

Among them, in the device startup process, the port status table can be initialized according to the port configuration mode, physical location and other information, and the port status table can be updated in real time according to a certain strategy.

In this embodiment, when the port state table is initialized, the physical location n and mode configuration n of the state table are initialized according to the physical port and configuration of the network device.

Triggering real-time updates includes, but is not limited to, changes in the physical status of the local port, detection or change of the port physical status/port mode triggered by man-machine commands or other operation and maintenance systems, and alarms that may cause the physical status of the port to change.

Among them, the port configuration mode has two modes: self-adaptive and mandatory (half-duplex, full-duplex).

1. Adaptive mode: The docking parties negotiate the docking parameters after the port is connected to match the best state. In the adaptive mode, as long as the hardware is connected, the sending port tx direction continuously sends /C/frames, that is, configuration (configuration) code stream, if the receiving port rx direction continuously receives /C/frames, it will return to the opposite end with ack response /C/frame, the port establishes a link after the opposite end receives it; 2. Mandatory mode, the port uses the parameters specified by the configuration for docking, divided into half-duplex and full-duplex. In forced mode, as long as the hardware is connected, the sending port tx direction will send /C/frames (ie idle frames) at a certain frequency. If the receiving port rx direction can receive /C/frames related to its own frequency, it is considered correct If the end attribute is consistent with the local end, the local port will establish a link.

Adaptive mode and mandatory mode can be used in different scenarios. When interconnecting Ethernet devices (including electrical ports and optical ports of different speeds), the basic principle is that the port configuration modes of the connected devices must be consistent. When the port configurations of the devices on both sides of the interconnection are inconsistent (mandatory at one end and adaptive at the other end), the port of the interconnected device may fail to establish a link.

Step 302: Detect the physical status of each port at the local end; in one embodiment, a timer T1 can be started to detect the actual link establishment status of each port at the local end at a certain frequency, and update the port state table according to the detection result. After the timer T1 expires, restart T1 to re-check the physical state of the port; use the timer T1 to detect whether the physical state of the port is stable, so as to avoid misjudgments caused by the unstable port physical state due to certain factors. Before the timer T1 expires, if the physical state of the monitored port remains stable, the judgment result is valid, and the physical state n of the local port in the state table is updated; otherwise the result in this period is invalid, and the physical state n of the local port in the state table is maintained constant.

The effective status of the port is UP or DOWN. When the effective state of the local port is detected as UP, the physical state of the port is judged to be UP, and when the effective state of the local port is detected as DOWN, the physical state of the port is judged to be DOWN; the detection frequency value is the number of sampling inspections according to a certain strategy , Ensure that the number of sampling inspections is at least ≥3 in the T1 period.

In one embodiment, the specific detection process includes: 1) Before T1 times out, the physical state n of the local port always remains UP (DOWN is not detected before T1 times out), then the physical state of the port is judged to be UP, and the state table is updated The physical state of the local port is n. And restart the T1 timer to re-check the physical state of the port; 2) Before T1 times out, the physical state n of the local port always remains DOWN (up is not detected before T1 times out), then the physical state of the port is judged to be DOWN and the state is updated Physical state n of the local port of the table. And restart the T1 timer to recheck the port physical state n; 3) Before T1 times out, the local port physical state n changes between UP and DOWN (up and DOWN are detected at the same time before T1 times out), then the state table is maintained The physical state n of the local port remains unchanged in the previous cycle. And restart the T1 timer to recheck the physical state of the port n.

Step 303, predict the configuration mode of each port of the opposite end; in one embodiment, the timer T2 can be started to directly detect at the physical layer whether the characteristic code stream received by the receiving Rx port of each port of the local end is /C/ Or /I/frame, and judge the peer port mode according to the detection result and update the predicted peer port configuration mode n in the port state table. After the T2 timer expires, restart the T2 timer to re-check the port receiving the Rx code stream; use the timer T2 to check whether the port receiving feature code stream is stable, so as to avoid misjudgment caused by the instability of the receiving feature due to certain factors. . Before the timer T2 expires, monitor that the status of the characteristic value of the received code stream at the local port n remains stable, and then judge the opposite port mode according to the valid characteristic value; otherwise, the detection in this cycle is invalid and the opposite port mode is judged to be unknown. Use the port mode judged in this cycle to update the predicted peer port configuration mode n in the state table.

It is predicted that the effective state of the configuration mode of the peer port is adaptive or mandatory. When the effective detection feature value is /C/frame, it is judged as adaptive; when the effective detection value is /I/frame and there is no /C/frame, it is judged that the port mode of the opposite end is mandatory.

The detection frequency value is the number of sampling tests according to a certain strategy to ensure that the number of sampling tests is at least ≥3 within the T2 period.

In one embodiment, the specific prediction process includes: 1) Before T2 times out, port n continuously detects /C/frames, then judges that the peer port configuration mode n is adaptive, and updates the predicted peer port configuration in the state table Mode n. And restart the T2 timer to re-check that the port receives the Rx code stream; 2) Before T2 times out, port n continues to detect /I/frames, and /C/frames are not detected, then it is judged that the configuration mode of the opposite port is mandatory, and Update the predicted peer port configuration mode n in the status table. And restart the T2 timer to re-check the Rx code stream of the receiving port; 3) When the detection condition of port n is different from the above two conditions before T2 times out, it is judged that the configuration mode of the opposite port is unknown, and the prediction pair in the status table is updated. End port configuration mode n. And restart the T2 timer, restart to detect the Rx code stream of the receiving port. Step 304: Compare the consistency between the local port configuration mode n in the port state table and the predicted counterpart port configuration mode n, and perform a configuration operation on the local port configuration mode n according to the physical state n of the local port. In an embodiment, the physical state of the local port is: UP or DOWN; the predicted configuration mode of the opposite port is: unknown, adaptive, mandatory; the local port configuration mode is: adaptive, mandatory.

When the physical status of the local port n is UP or DOWN, the following contents are included.

When the physical status of the local port is judged to be UP, compare the predicted peer port configuration mode n with the local port configuration mode n: 1) When the predicted peer port configuration mode n is consistent with the local port configuration mode n, Keep the current configuration mode n of the local port unchanged; 2) When the predicted configuration mode of the opposite port n is unknown, keep the current configuration mode n of the local port unchanged; 3) When the predicted configuration mode n of the opposite port is the same as the local When the configuration mode n of the end port is inconsistent, keep the current configuration mode n of the local port unchanged, and proceed to 4.1.

In one embodiment, both the predicted peer port configuration mode and the local port configuration mode can be displayed in real time through the operation and maintenance interface.

3.2. When the physical status of the local port is DOWN, compare the consistency between the local port configuration mode n and the predicted peer port configuration mode n: 1) When the predicted peer port configuration mode n is unknown, modify the local End port configuration mode n, and transfer to 4.2 processing; in one embodiment, according to the current value of the local port configuration mode n (adaptive or mandatory), modify the local port mode n in the reverse direction, for example, the local port configuration mode n is current If it is self-adaptive, change it to mandatory, and if it is currently mandatory, change it to adaptive.

2) When the predicted peer port configuration mode n is clear (adaptive or mandatory) and is inconsistent with the local port configuration mode n, modify the local port configuration mode n to the peer port configuration mode n, and go to 4.2 Processing; In one embodiment, the local port configuration mode n is modified according to the current value (adaptive or mandatory) of the predicted peer port configuration mode n. For example, if the peer port configuration mode n is currently adaptive, the local port The configuration mode n is changed to adaptive, and the peer port configuration mode n is currently mandatory, then the local port configuration mode n is changed to mandatory.

3) When the predicted peer port configuration mode n is clear (adaptive or mandatory) and consistent with the local port configuration mode n, keep the current local port configuration mode n unchanged, and proceed to 4.3.
