Description
Technical Field
The present invention relates to, but not limited to, ethernet technology, and more particularly, to a method and apparatus for managing port configuration modes.
Background
In the process of interfacing ethernet devices, except for ensuring normal physical connection during general interfacing, it is generally required that the port configuration modes of both interfacing sides must be kept consistent, otherwise, a fault may occur.
In practical applications, it often happens that after a docking device is restarted for some reason (such as device power failure or active operation), the physical state of a device docking port is a DOWN fault (hereinafter, the device is referred to as a home device). This situation can cause traffic and management interrupts to be carried on the port. The reason for the failure is often found to be that the port configuration modes of the two docking devices are inconsistent, and in the prior art, the port configuration modes of the two docking devices need to be modified by the two docking parties so as to keep the two docking devices consistent. And the local terminal equipment cannot remotely modify the port configuration mode due to the off-pipe, so that the modification is difficult.
In network construction, the docking equipment may belong to different operation and maintenance parties, and cannot be monitored through a unified operation and maintenance platform, so that it cannot be ensured that the port configuration modes of the docking equipment are kept consistent, and further maintenance cost is increased. In the long-term operation and maintenance process of the network device, situations such as device replacement, configuration modification and the like also exist, and the configuration mode of the docking port may be modified, so that the configuration mode of the docking port may be inconsistent. Further, although a link may be established when the configuration modes of the docking ports are not consistent, when the behavior operation of the network device is changed due to software update or the like, the link cannot be established for the docking ports.
Disclosure of Invention
In view of this, an embodiment of the present invention provides a method for managing a port configuration mode, including:
comparing the consistency of the local terminal port configuration mode and the predicted opposite terminal port configuration mode;
and setting the configuration mode of the local port according to the physical state and the consistency of the local port.
The embodiment of the invention also provides a device for managing the port configuration mode, which comprises the following components:
the comparison unit is used for comparing the consistency of the local terminal port configuration mode and the predicted opposite terminal port configuration mode;
and the setting unit is used for setting the configuration mode of the local port according to the physical state and the consistency of the local port.
An embodiment of the present invention further provides a computer-readable storage medium, where an information processing program is stored, and when the information processing program is executed by a processor, the information processing program implements the steps of the method for managing a port configuration mode.
Compared with the prior art, the technical scheme provided by the embodiment of the invention can automatically set the port configuration mode of the home terminal, and ensures the stability of the service of the network equipment.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
In the prior art, when network devices are connected, port negotiation is performed according to respective port configuration modes. When the two-port mode negotiation depends on the respective port configuration. When the two-port mode (adaptive/mandatory) configuration is inconsistent, it may cause the port not to work normally (even if the port works normally, there is a hidden danger).
In addition, since the network docking device may perform management and maintenance separately in terms of physical location and logical relationship, it is difficult to perform unified management and query on the above two-port configuration, that is, it is difficult to perform processing when a problem occurs.

if the physical state of the local port is DOWN, restarting the local port again after T4 exceeds the time limit, detecting the physical state of the local port, and N = N +1;
and stopping the operation of the local port when the N reaches a threshold value.
Before comparing the consistency of the local port configuration mode and the predicted opposite port configuration mode, the method further comprises the following steps:

and when the detection is invalid, predicting that the opposite end port configuration mode is unknown.
Before detecting the feature code stream sent by the opposite end port received by the local end port, the method further includes: starting a timer T2;

And the notification message or the alarm message carries the geographic position of the local port and/or the geographic position of the opposite port.
Fig. 2 is a flowchart illustrating a method for managing a port configuration mode according to another embodiment of the present invention, as shown in fig. 2, the method includes:
and judging the physical state of the local port by detecting the effective state of the local port. For example, the port active state is UP or DOWN. When the effective state of the port of the local end is detected to be UP, the physical state of the port is judged to be UP, and when the effective state of the port of the local end is detected to be DOWN, the physical state of the port is judged to be DOWN.
Specifically, the timer T1 may be started to detect the physical state of the local port at a certain frequency. Through the timer T1, whether the physical state of the port is stable or not can be detected, so that misjudgment caused by instability of the physical state of the port due to certain factors can be avoided. Before the timer T1 is overtime, the physical state of the monitoring port is kept stable, the judgment result is valid, otherwise, the result in the period is invalid. For example, in T1, if the detected port physical state is DOWN or UP all the time, the state is stable, and if the detected port physical state is DOWN once and UP once, the state is unstable. And after the T1 timer is overtime, restarting the T1 timer and re-detecting the physical state of the port.
The detection frequency value in T1, namely the sampling detection frequency, can be selected according to a certain strategy, so that the sampling detection frequency is at least more than or equal to 3 in the T1 period.
the configuration mode of the opposite port can be predicted by detecting whether the characteristic code stream received by the Rx receiving port of the local port is/C/I/frame. For example, the predicted peer port configuration mode valid state is adaptive or mandatory. When the detected characteristic code stream value is/C/frame, the self-adaption is judged; and when the detected characteristic code stream is/I/frame and no/C/frame, judging that the opposite terminal port mode is mandatory.
Specifically, the timer T2 may be started, and the feature code stream received by the Rx port may be directly detected in the physical layer. And detecting whether the characteristic code stream received by the port is stable or not through the timer T2 so as to avoid misjudgment caused by instability of the characteristic code stream received by certain factors. Before the timer T2 is overtime, monitoring that the state of the code stream characteristic value received by the local terminal port is stable, and predicting the configuration mode of the opposite terminal port according to the code stream characteristic value; otherwise, the detection in the period is invalid, and the opposite terminal port mode is judged to be unknown. For example, in T2, if the detected code stream characteristic value is always/C/, it indicates that the code stream characteristic value remains stable, and it is determined that the opposite-end port configuration mode is adaptive; for example, if the detected code stream characteristic value is/C/, and the other is/I/frame, etc., it indicates that the code stream characteristic value is unstable, the detection is invalid, and the opposite-end port mode is predicted to be unknown. And after the T2 timer is overtime, restarting the T2 timer and re-detecting the physical state of the port.
The detection frequency value in T2, namely the sampling detection frequency, can be valued according to a certain strategy, so that the sampling detection frequency is at least more than or equal to 3 in the T2 period.
Wherein, the physical port state of the home terminal is: UP or DOWN; the predicted opposite port configuration mode is as follows: unknown, adaptive, mandatory; the port configuration mode of the home terminal is as follows: self-adapting and forcing.
Under two scenes that the physical state of a local terminal port is UP or DOWN respectively, the method comprises the following steps:

1) When the predicted opposite end port configuration mode is unknown, the local end port configuration mode is reversely modified and processed by 2.2;
specifically, the home port mode is reversely modified according to the current value (adaptive or mandatory) of the home port configuration mode, for example, the current value of the home port configuration mode is modified into mandatory when the current value is adaptive, and modified into adaptive when the current value is mandatory.
2) When the predicted opposite end port configuration mode is definite (self-adaptive or forced) and is inconsistent with the local end port configuration mode, the local end port configuration mode is modified into the opposite end port configuration mode, and 2.2 processing is carried out;
specifically, the home port configuration mode is modified according to the current value (adaptive or mandatory) of the predicted opposite port configuration mode, for example, if the opposite port configuration mode is currently adaptive, the home port configuration mode is modified to be adaptive, and if the opposite port configuration mode is currently mandatory, the home port configuration mode is modified to be mandatory.
3) And when the predicted opposite end port configuration mode is definite (self-adaptive or mandatory) and is consistent with the local end port configuration mode, keeping the current local end port configuration mode unchanged, and performing 2.3 processing.
2.1, starting a timer T3, monitoring the physical state of the local port, and providing a notification or alarm message according to the detection result:
the physical state of the port of the home terminal is as follows: UP or DOWN;
1) And if the physical state of the local port is kept to be UP before T3 is overtime, generating a notification message (notification 1: used for informing the opposite terminal port configuration mode not consistent with the local terminal port configuration mode);
2) And if the T3 is overtime, the physical state of the port shakes, and an alarm message is generated (alarm 1: used for informing that the physical state of the local terminal port is unstable and that the opposite terminal port configuration mode is inconsistent with the local terminal port configuration mode);
3) And if the physical state of the port of the home terminal is changed into DOWN before T3 is overtime, the processing is switched to 1.2.
The method comprises the steps of providing notification or alarm information, recording a log, wherein the log content comprises a current configuration mode of a local port, whether the configuration mode is modified, if so, the record and the reason of modification and the like.
2.2, starting a timer T3, monitoring the physical state of the local port, and providing a notification or alarm message according to the detection result:
the physical state of the port of the home terminal is as follows: UP or DOWN;
1) If the physical state of the port of the local end is kept to be DOWN before T3 is overtime, the mode of the port of the local end is reversely modified again, namely the original configuration mode is recovered; and generates an alarm message (alarm 2: used to inform the local port of the physical state abnormity and the configuration mode of the opposite port is inconsistent with that of the local port);
2) If the physical state of the local port is jittered before T3 is overtime, the local port mode is reversely modified again, namely the original configuration mode is recovered; and generates an alarm message (alarm 1: used to inform the physical state of the port of the local terminal to be unstable and the configuration mode of the port of the opposite terminal to be inconsistent with the configuration mode of the port of the local terminal);
3) If T3 is overtime and the physical state of the local port is changed into UP, the current port configuration mode is not modified, and a notification message is generated (notification 2: for notifying that the home port configuration mode has been modified, and that the peer port configuration mode is inconsistent with the home port configuration mode).
The log content includes the current configuration mode of the local port, whether the configuration mode is modified, if so, the modified record and reason, and the like.

And when the N reaches the threshold value, stopping the operation on the port.
Wherein, the threshold value can be artificially set according to a certain rule.
In which, a log is also recorded, and the log content includes, but is not limited to, port configuration/status, restart reason/number, etc.
The notification message or the alarm message in 2.1 or 2.2 may be reported to a network manager or other operation and maintenance platforms. The notification message or the alarm message can also carry information such as the physical position of the port of the home terminal/the opposite terminal, and operation and maintenance personnel can conveniently operate on site.
According to the technical scheme provided by the embodiment, a code stream is directly received through a detection port, the port configuration mode of opposite-end equipment is judged according to the port mode characteristic code stream, and then the port configuration mode of the local end is adjusted and set according to the physical state of the port of the local end and the comparison between the port configuration mode of the local end and the port configuration mode of the opposite end; therefore, on the basis of the conventional equipment negotiation standard, any change on the butt joint equipment is not required, and the equipment has good compatibility;
in addition, the method and the device aim at the problems that in the prior art, the port configuration mode of the docking equipment depends on the negotiation between the two parties, and the ports of the equipment at the home terminal and the opposite terminal need to be managed and maintained respectively, so that the port mode negotiation depends on the configuration between the two parties for docking, the positioning efficiency is low, and the like. The scheme of the embodiment smoothly processes possible jitter in the port docking negotiation by adopting a method of timer detection and counter processing for the port state and the related fault processing. And the configuration mode of the opposite terminal port is judged according to the port protocol interaction, and judgment and processing are carried out by combining the state, the configuration mode and the like of the local terminal port, so that the scheme is simple and flexible, and large-scale deployment and application are easy.
Fig. 3 is a flowchart illustrating a method for managing a port configuration mode according to another embodiment of the present invention.
In this embodiment, the home device is provided with n ports, and automatic detection and recovery of the port configuration mode need to be implemented for the n ports.
As shown in fig. 3, the method includes:
the format of the port status table is as follows: { port number 1, physical location 1, home port configuration mode 1, home port physical state 1, and predicted opposite port configuration mode 1; port number 2, physical position 2, home port configuration mode 2, home port physical state 2, and predicted opposite port configuration mode 2; the electric power supply unit is connected with the power supply unit; port serial number n, physical position n, home port configuration mode n, home port physical state n, and predicted opposite port configuration mode n; }
It can also be as shown in table 1:
the initialization of the port state table can be completed according to information such as port configuration mode, physical position and the like in the starting process of the equipment, and the real-time updating of the port state table is completed according to a certain strategy.
In this embodiment, when initializing the port state table, the physical location n and the mode configuration n of the state table are initialized according to the physical port and configuration of the network device.
Triggering real-time update includes but is not limited to the occurrence of a change in the physical state of the local port, detection or change of the physical state/port mode of the port triggered by a man-machine command or other operation and maintenance system, an alarm that may cause a change in the physical state of the port, and the like.
The port configuration mode comprises the following steps: adaptive and forced (half duplex and full duplex).
1. An adaptive mode: after the connection of the ports, the two docking parties negotiate the docking parameters to match the best state. In the self-adaptive mode, as long as after hardware connection, a transmitting port tx direction continuously transmits/C/frames, namely configuration (configuration) code streams, if the receiving port rx direction continuously receives/C/frames, the receiving port rx direction returns/C/frames with ack response at the opposite end, and the opposite end receives the back port and establishes a link;
2. in the forced mode, the ports adopt parameters specified by configuration for butt joint, and the parameters are divided into half duplex and full duplex. In the mandatory mode, as long as the hardware is connected, the tx direction of the transmitting port will transmit/C/frame (i.e. idle frame) at a certain frequency, and if the rx direction of the receiving port can receive/C/frame related to its own frequency, the peer end attribute is considered to be consistent with the peer end, and the peer end port will establish a link.
The adaptive mode and the mandatory mode can be used in different scenes, and when the Ethernet equipment (including electric ports and optical ports with different rates) is docked, the basic principle is that the port configuration modes of the equipment of the two docked parties must be kept consistent. When the configurations of the device ports of the two docking parties are inconsistent (one-end forcing and one-end self-adapting), the docking device ports cannot build a link.
specifically, the timer T1 may be started, the actual link establishment state of each port of the local terminal may be detected at a certain frequency, and the port state table may be updated according to the detection result. Restarting the T1 after the timer T1 is overtime, and detecting the physical state of the port again;
whether the physical state of the port is stable or not is detected through the timer T1, so that misjudgment caused by instability of the physical state of the port due to certain factors is avoided. Before the timer T1 is overtime, the physical state of the monitoring port is kept 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 the period is invalid, and the physical state n of the local port in the state table is maintained unchanged.
The port active state is UP or DOWN. When detecting that the effective state of the port of the local terminal is UP, judging that the physical state of the port is UP, and when detecting that the effective state of the port of the local terminal is DOWN, judging that the physical state of the port is DOWN;
the detection frequency value, namely the sampling detection frequency, is selected according to a certain strategy, and the sampling detection frequency is ensured to be at least more than or equal to 3 in a T1 period.
Wherein, the concrete detection process includes:
1) And before T1 overtime, the physical state n of the port of the local end is kept to be UP all the time (DOWN is not detected before T1 overtime), the physical state of the port is judged to be UP, and the physical state n of the port of the local end in the state table is updated. Restarting the T1 timer, and detecting the physical state of the port again;
2) And before T1 overtime, the physical state n of the port of the local end is always kept as DOWN (UP is not detected before T1 overtime), the physical state of the port is judged to be DOWN, and the physical state n of the port of the local end in the state table is updated. Restarting the T1 timer, and detecting the physical state n of the port again;
3) And before T1 overtime, the physical state n of the local port changes between UP and DOWN (UP and DOWN are detected simultaneously before T1 overtime), and the physical state n of the local port in the state table is kept unchanged in the last period. And restarting the T1 timer and detecting the physical state n of the port again.
specifically, the timer T2 may be started, and the physical layer directly detects whether the characteristic code stream received by the Rx receiving port of each port of the local terminal is/C/or/I/frame, and determines the peer port mode according to the detection result and updates the predicted peer port configuration mode n of the port state table. Restarting the T2 timer after the T2 timer is overtime, and re-detecting the Rx code stream received by the port;
and detecting whether the characteristic code stream received by the port is stable or not through the timer T2 so as to avoid misjudgment caused by instability of the characteristic code stream received by certain factors. Before the timer T2 is overtime, monitoring the state of the code stream characteristic value received by the port n of the local terminal to be stable, and judging the mode of the port of the opposite terminal according to the effective characteristic value; otherwise, the detection in the period is invalid, and the opposite terminal port mode is judged to be unknown. And updating the predicted opposite terminal port configuration mode n in the state table by using the port mode judged in the period.
And predicting the valid state of the opposite terminal port configuration mode to be self-adaptive or mandatory. When the detected effective characteristic value is/C/frame, the self-adaption is judged; when the effective value is detected to be/I/frame and no/C/frame exists, the opposite terminal port mode is judged to be mandatory.
The detection frequency value, namely the sampling detection frequency is valued according to a certain strategy, so that the sampling detection frequency is at least more than or equal to 3 in a T2 period.
The specific prediction process comprises the following steps:
1) And before T2 is overtime, the port n continuously detects/C/frame, the opposite terminal port configuration mode n is judged to be self-adaptive, and the predicted opposite terminal port configuration mode n in the state table is updated. Restarting the T2 timer, and re-detecting the Rx code stream received by the port;
2) And before T2 is overtime, the port n continuously detects the I/frame, and if the I/frame is not detected, the port n judges that the opposite port configuration mode is mandatory, and updates the predicted opposite port configuration mode n in the state table. Restarting the T2 timer, and re-detecting the Rx code stream of the receiving port;
3) And before T2 is overtime and the detection condition of the port n is different from the two conditions, judging that the opposite terminal port configuration mode is unknown, and updating the predicted opposite terminal port configuration mode n in the state table. And restarting the T2 timer, and restarting the Rx code stream of the detection receiving port.
