Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It is to be noted that, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
At present, all kinds of switches on the market have all possessed POE power supply function mostly, and the POE power supply of each net gape of the switch of different grade type all has certain power limitation, in the switch course of operation, when instantaneous power exceedes the restriction or long-time power exceedes the restriction appears in arbitrary net gape, also when instantaneous or long-time overload appears in the power supply, all can trigger the hardware self-protection function of switch, also the power supply of the net gape that transships is directly turn-off to the main control chip of switch, or when there is the network management system in the system, the power supply of the net gape that is overloaded is turned off by network management system control, in order to maintain the stability of other power supply ports. However, in the practical application process, the inventor finds that in the above-mentioned traditional POE power supply stability maintaining method for the switch, after the network port of the switch is overloaded and powered off, the switch does not have a corresponding self-healing function, and usually needs a maintainer to manually recover from the network port going to the station, and the network port offline rate is high and the number of times of maintenance for going to the station is large, thereby greatly increasing the maintenance cost in the practical application.
In view of the above-mentioned drawbacks of the conventional manner for maintaining the stability of the power over POE power of the switch, referring to fig. 1, in an embodiment, a method for recovering an abnormal power over POE power of the switch is provided, which includes the following steps S12 to S18:
and S12, acquiring the power supply state information of each network port and determining the current protection state of each network port.
It can be understood that the power supply state information refers to record information of power supply states corresponding to each network port of the switch, and is used for marking whether each network port triggers a self-protection function of the switch currently. The power supply state information may be a power supply state obtained by recording the state of each network port in real time or periodically by the switch itself, a power supply state obtained by monitoring the state of each network port in real time or periodically by an external network port monitoring device, or a power supply state of each network port obtained by the switch requesting to obtain from an external database or obtained from other monitoring terminals, and the specific power supply state information may be obtained in a manner determined according to the function of the switch itself and the network system where the switch is located in the practical application, as long as the required power supply state information of each network port can be reliably obtained.
The protection state refers to a hardware protection state or a non-hardware protection state of each network port of the switch. The hardware protection state is a power-off state which is automatically triggered by the switch when each network port is instantaneously overloaded or overloaded for a long time, otherwise, the non-hardware protection state is a power-on state which is continuously powered on when each network port is not instantaneously overloaded or the switch is automatically triggered by not being overloaded for a long time.
Specifically, after the switch acquires the power supply state information of each network port, it may directly determine, from the power supply state information, whether each network port is currently in a hardware protection state or a non-hardware protection state, so as to perform corresponding subsequent control processing for two different protection states, respectively.
And S14, respectively detecting the current and the voltage of each network port currently in the non-hardware protection state, and determining the detection power of each network port currently in the non-hardware protection state.
It can be understood that, during the operation of the switch, the switch performs current and voltage detection on all the network ports currently in the non-hardware protection state to obtain the current value and the voltage value of each network port. Therefore, the switch calculates the current actually detected power supply power of each network port according to the current value and the voltage value of each network port, namely the current detected power of each network port in the non-hardware protection state.
S16, determining a power supply abnormal network port and closing the power supply of the power supply abnormal network port according to the comparison result of each detection power and a preset software power threshold value; and the power supply abnormal network port is a network port with detection power larger than the software power threshold value.
The preset software power threshold is a power threshold for triggering a software protection function, which is determined according to a hardware protection power threshold of the network port, which is determined by the switch itself. The software power threshold needs to be smaller than the hardware protection power threshold, so that when each network port is overloaded instantaneously or for a long time, the power supply abnormal port is effectively determined, and the POE power supply abnormal recovery is carried out through other processing steps.
Specifically, after obtaining the detection power of each network port currently in the non-hardware protection state, the switch respectively compares the detection power of each network port with a preset software power threshold to obtain each comparison result. And if the detection power of the network port in the comparison result is greater than the software power threshold, determining the network port as the abnormal power supply network port, and further closing the power supply of the abnormal power supply network port by the switch so as to maintain the stable power supply of other normal network ports of the switch and prevent the device damage of the abnormal power supply network port caused by long-time overload. The number of the power supply abnormal network ports can be one or more, and is determined by a comparison result of the detected power in the actual working process of the switch.
And S18, restoring the power supply of the power supply abnormal network port after the set time length.
It can be understood that the set time duration is a time interval, such as but not limited to 30s or 60s, for restarting the power supply of the network interface, which is set for the switch in advance according to the maintenance record, experience and the like of the switch in practical application, as long as the service processing of the switch can be effectively prevented from being influenced by long-time power failure of the network interface with abnormal power supply, and the network interface can be prevented from being damaged due to too short interval time for restarting the power supply.
Specifically, the switch will wait for the power supply of the power supply abnormal network interface to be restarted after the set time is long after the power supply of the power supply abnormal network interface is closed, so as to recover the power supply of the power supply abnormal network interface, thereby realizing the self-recovery of the network interface POE of the switch after the power supply abnormality and avoiding the restart of the maintenance personnel when the maintenance personnel go to the station.
According to the method for recovering POE power supply abnormality of the switch, whether the protection state of each network port is in the non-hardware protection state or not is determined according to the power supply state of each network port, then the current voltage of each network port in the non-hardware protection state is detected respectively, the detection power of each network port in the non-hardware protection state is determined, the detection power is compared with a software power threshold value, the power supply of the network port with abnormal power supply is determined, the power supply of the network port with abnormal power supply is closed, the power supply of the network port with abnormal power supply is recovered after a set time length, protection and self-recovery when POE power supply of the switch is abnormal are achieved, the network port offline rate and the number of on-site maintenance times when POE power supply of the network port is abnormal are greatly reduced, and the purpose of greatly reducing maintenance cost is achieved.
In one embodiment, the software power threshold is less than a hardware protection power threshold of the switch fabric. It can be understood that, in this embodiment, the software power threshold of the switch port is set to be smaller than the hardware protection power threshold of the switch port, and under the condition that any port of the switch is instantaneously overloaded or overloaded for a long time, a software protection and recovery mechanism is preferentially triggered, that is, the power supply recovery of the power supply abnormal port is preferentially realized by the switch POE power supply abnormal recovery method, so that the offline rate of the port caused by the power supply abnormality is reduced to the maximum extent, the time consumed for recovering the power supply abnormal port of the switch POE is reduced, and the recovery processing efficiency is improved.
Referring to fig. 2, in an embodiment, the method for recovering power failure of POE switch may further include the following processing step S13:
and S13, if any network port is in the hardware protection state, restarting the power supply of the network port in the hardware protection state.
It can be understood that, after the switch acquires the power supply state information of each network port, it determines that any network port is currently in the hardware protection state, and then the switch software self-healing process is reopened to recover the power supply of the network port currently in the hardware protection state, so that the network port exits the hardware protection state, which is convenient for the switch to detect the current and voltage of the network port subsequently, and thus determine whether the network port belongs to the self-protection caused by the instantaneous overload or the long-time overload, so as to perform the corresponding power supply abnormal recovery.
Through the step S13, when any network port is currently in the hardware protection state, the switch may automatically reopen the power supply of the network port, so that the switch may perform corresponding network port current and voltage detection after the network port recovers power supply, and determine whether the network port still belongs to the abnormal power supply network port, if not, the network port may directly maintain the online state of normal power supply, and if so, the power supply abnormal recovery processing may be completed through the subsequent processing steps, so that the network port recovers the online state of normal power supply, thereby further reducing the network port offline rate of the switch.
Referring to fig. 3, in an embodiment, the step S12 may specifically include the following processing steps S122 and S124:
s122, respectively reading the value of the power supply state register of each network port in a set period;
and S124, determining the current protection state of each network port according to the value of each power supply state register.
It can be understood that the set period is a state reading period set according to the failure probability, test experience, or other maintenance experience of the switch in practical application, for example, but not limited to, 1min, 3min, or other periods, as long as the switch can effectively read the value of the power supply state register of each network port to ensure the effectiveness and accuracy of the subsequent processing step. The value of the power supply state register refers to each state register which records the POE power supply state of each network port in the switch, and the switch can directly read the value of each power supply state register to directly know the current protection state of each corresponding network port.
Specifically, in this embodiment, the switch directly reads the value of each power supply status register, so as to directly determine whether each corresponding network port is currently in the hardware protection state or the non-hardware protection state according to the value of each power supply status register. Through the steps S122 and S124, the switch can efficiently determine the protection state of each corresponding portal, thereby saving the processing flow of state judgment and further improving the efficiency of recovery processing.
Referring to fig. 4, in an embodiment, the step S16 may specifically include the following processing steps S162 to S166:
s162, comparing each detection power with a software power threshold value;
s164, if any detection power is larger than the software power threshold, accumulating the overload times of the corresponding network port;
and S166, if the overload times exceed the set times, determining that the corresponding network port is the abnormal power supply network port.
The set times refers to an overload time threshold determined according to test experience of the switch in practical application, and can be used for ensuring the accuracy of judging the power supply abnormal network port by the switch and avoiding long-time overload damage of the network port or increase of network port detection burden of the switch caused by excessive judgment times. The set number of times may be, for example, 3 times, 2 times, 4 times, or other times, and accordingly, when the overload number continuously (i.e., detected up to now) exceeds 3 times or 4 times, it may be determined that the network port corresponding to the overload number is the power supply abnormal network port.
Specifically, when the switch determines whether any network port subjected to instantaneous overload or long-time overload is an abnormal power supply network port, the switch may first compare the detection power of the network port with a determined software power threshold value to determine whether the current detection power of the network port exceeds the software power threshold value. When the switch determines that the detected power of any network port is greater than the software power threshold, the network port is not directly determined as a power supply abnormal network port, but the overload times of the network port are accumulated once, for example, the current overload times of the network port is added by 1. And then, the exchanger compares the overload frequency after the network port is refreshed with the set frequency, and if the overload frequency after the network port is refreshed exceeds the set frequency, the network port is determined to be the abnormal power supply network port, so that the subsequent abnormal power supply outage and recovery processing are carried out.
Through the processing steps from S162 to S166, the switch can effectively avoid misjudgment of the power supply abnormal network port, so that the self-recovery efficiency of the switch when the POE power supply is abnormal is further improved.
Referring to fig. 5, in an embodiment, the method for recovering a POE power supply abnormality of a switch may further include the following processing steps:
if the overload count does not exceed the set count, the process returns to step S12.
It can be understood that, in the foregoing embodiments, the POE power supply abnormality recovery processing performed by the switch on each network port may be one-time recovery processing, or may be continuous online POE power supply abnormality detection and recovery processing that is remotely controlled by a maintenance person. Specifically, in this embodiment, the switch may set the corresponding overload times limit for each network port of the switch, so that when some network port or some network ports are overloaded in the current detection and recovery process, the switch counts the overload times of the corresponding network ports. Therefore, when the switch detects each network port, for any network port, the current overload frequency of the network port does not exceed the set frequency, the switch does not immediately determine the network port as a power supply abnormal port, but can judge the protection state of the network port again, and if the switch determines that the network port is a non-power supply abnormal port in the subsequent process, the switch does not need to perform outage and self-recovery processing, so that the misjudgment rate of the overload of the network port is reduced. The loop judgment processing for other network ports can be understood by referring to the same principle of the foregoing example.
Through foretell circulation processing, can reduce the erroneous judgement rate to each net gape overload, realize the online circulation detection of the power supply anomaly, the net gape POE power supply anomaly self-healing ability of reinforcing switch simultaneously, can also save the system resource of switch and reduce the energy consumption.
In an embodiment, as shown in fig. 5, the method for recovering POE power supply abnormality of a switch may specifically include the following processing steps:
if any of the detected powers is smaller than the software power threshold, the process returns to step S12.
Specifically, when the switch performs overload detection comparison on each network port, for any network port, when the detection power of the network port is smaller than the software power threshold, it indicates that the network port is not overloaded again. Then, the switch can reacquire the power supply state information and judge the protection state of the network port, so as to realize real-time online cycle detection of the network port and improve the power supply abnormality detection efficiency of the network port.
In an embodiment, as shown in fig. 5, after the step S18, the method may further include the following steps:
the above step S12 is executed again.
Specifically, after the switch completes the current round of power supply abnormity recovery for each network port, the switch can judge the protection state of each network port again, and start a new round of POE power supply abnormity detection and self-recovery processing. It can be understood that, in all different network ports of different switches, the POE power supply abnormality detection and self-recovery processing cycle times of different network ports may be the same or different, and the actual progress of POE power supply abnormality detection and self-recovery processing can be determined by the switch respectively for each network port.
Through the above-mentioned circulation processing steps, the switch can automatically and quickly complete the self-recovery processing of the power supply abnormal network port when POE power supply abnormality occurs at any network port. Afterwards, the switch can also continue the abnormal state of this net gape after recovering of on-line measuring to realize the unusual automated inspection of net gape POE power supply and the self-recovery of switch in whole course of the work, reduce the off-line rate of each net gape of switch more effectively, further promote the self-healing ability of switch, reduce the maintenance cost.
It should be understood that, although the steps in the flowcharts of fig. 1 to 5 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1-5 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performing the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.
