When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.

Referring to fig. 1, fig. 1 is a schematic diagram of an indicator light control scheme of a network device shown in the present application;

as shown in fig. 1, the network device includes a chip, a logic device, at least one network port, and an indicator light corresponding to the network port.

The indicator light may indicate the status of the network port based on a received signal, which is commonly referred to as a lighting signal.

For example, the lighting signal may be represented by bit, and if 0 indicates off and 1 indicates on, the lighting signal indicating that the indicator is off is 000 … …, and the lighting signal indicating that the indicator is normally on is 111 … ….

The network device usually has a plurality of network ports, and in order to clearly indicate the status of the network ports, a plurality of indicator lights are usually provided corresponding to the network ports. When receiving the lighting signal, in order to enable each indicator lamp to simultaneously display the state of the corresponding network port, it is necessary to simultaneously receive each lighting signal, that is, to perform parallel processing on the lighting signal.

Continuing with the example, assuming that there are 6 network interfaces and 6 corresponding indicator lights in the network device, if the indicator lights 1, 5, and 6 are turned off and the indicator lights 2, 3, and 4 are normally on, the parallel lighting signal of the indicator lights can be represented as 011100 by bit, as shown in the following table 1:

indicator light	1	2	3	4	5	6
							Lighting signal	0	1	1	1	0	0

TABLE 1

Usually, a chip in the network device may send a lighting signal to the indicator lamp according to the detected status of the network port. The chip may be a PHY (Physical layer) chip or a switch chip.

When the PHY chip sends the lighting signal, the PHY chip is positioned at the physical layer of the port, and can directly output the parallel lighting signal to the connected indicator lamps; the lighting signal issued by the switching chip is a serial lighting signal, and the serial lighting signal needs to be converted into a parallel lighting signal by a serial-to-parallel conversion chip or a CPLD (Complex Programmable Logic Device) chip, and then the parallel lighting signal is output to the indicator light.

The above two ways of sending down the lighting signal to control the indicator light may be referred to as hardware lighting.

In the related art, the indicator lamp switches different display modes based on the received lighting signal, and can indicate the basic state of the network port to the user.

For example, the base state includes, but is not limited to, the following states: a connection state of a network port, a half/full duplex mode, a data transceiving state, and the like.

However, whether the PHY chip or the switch chip is used, the network port status information that can be indicated by the issued lighting signal is limited. When the network port has an abnormal event, the chip can detect the abnormal state of the network port but cannot control the indicator lamp to indicate through the lighting signal.

Especially, when a CRC packet loss event occurs at a network port, there may be a risk that a network device may not work normally or even crash, which requires a related person to timely determine whether a CRC packet loss occurs at the network port.

Therefore, in order to avoid a fault caused by a CRC packet loss event occurring at a network port, the state of the network port needs to be monitored, and whether the CRC packet loss event occurs at the network port is timely discovered.

In view of this, the present application provides a technical solution, where when the processor determines that a CRC packet loss event occurs at a network port, the processor issues an indicator light control signal corresponding to the CRC packet loss event.

When the CRC packet loss event occurs to the network port, a control signal corresponding to the CRC packet loss event is issued to the logic device of the control indicator lamp so that the logic device controls the indicator lamp to switch to a display mode corresponding to the CRC packet loss event.

The indicating lamps correspond to the network ports one to one, and related personnel can simply and visually acquire the states of the network ports by observing the display modes of the indicating lamps.

In the technical scheme, the CRC packet loss event occurring at the network port is displayed through the indicator lamp, and related personnel can simply and intuitively rapidly judge whether the CRC packet loss event occurs at the network port corresponding to the indicator lamp by observing the display mode of the indicator lamp.

Next, examples of the present application will be described in detail.

Referring to fig. 2, fig. 2 is a flowchart illustrating an indicator light control method according to an exemplary embodiment of the present application, applied to a network device, where the network device includes a processor, at least one network port, and a logic device for controlling the indicator light; the indicator lamps correspond to the network ports one by one; the method comprises the following steps:

step 201, the processor determines whether a CRC packet loss event occurs at the network port;

step 202: if the CRC packet loss event occurs at the network port, the processor issues a control signal corresponding to the CRC packet loss event to the logic device;

step 203: and the logic device controls the indicator light to be switched to a display mode corresponding to the CRC packet loss event based on the control signal.

In this embodiment, the processor of the network device first needs to determine whether a CRC packet loss event occurs on the network port.

The processor can judge whether a CRC (cyclic redundancy check) packet loss event occurs to the network port by acquiring the state of the network port; and whether the CRC packet loss event occurs to the network port can be judged by receiving information reported by a chip for detecting the state of the network port.

In an illustrated embodiment, the processor may query the state information of the network port based on a preset period, and determine that a CRC packet loss event occurs in the network port when it is queried that a CRC packet loss abnormal state occurs in the network port.

For example, the CPU of the network device may periodically query the traffic condition of the network port at regular intervals, and if the CRC packet loss of the network port is found, the CPU determines that the CRC packet loss event occurs in the network port.

A person skilled in the art may set the query period as needed, or adjust the query period according to the frequency of the CRC packet loss event of the network port, which is not limited in the present application.

In this embodiment, when the processor determines that a CRC packet loss event occurs at the network port, the processor generates a control signal corresponding to the CRC packet loss event and issues the control signal to the logic device.

For example, when the CPU determines that a CRC packet loss event occurs at a certain network port, in order to enable the indicator light corresponding to the network port to be switched to the display mode corresponding to the CRC packet loss event, the CPU generates a control signal for controlling the indicator light and issues the control signal to the logic device.

It is worth noting that since a network device typically has a plurality of network ports, and a plurality of indicator lights corresponding to the network ports. When CRC packet loss occurs in a plurality of network ports, in order to enable each indicator light to indicate simultaneously, it is necessary to receive control signals simultaneously, that is, to process the control signals in parallel.

For example, assume that there are 6 network interfaces for a network device, and correspondingly 6 indicator lights. If CRC packet loss events occur at the network ports 2 and 4, and a control signal sent by the processor is represented by a bit; wherein, each bit defaults to 0, and 1 represents that CRC packet loss event occurs at the network port; the control signal of the indicator light can be expressed as 010100 as shown in table 2 below:

indicator light	1	2	3	4	5	6
							Control signal	0	1	0	1	0	0

TABLE 2

In this embodiment, the logic device controls the indicator light to switch to the display mode corresponding to the CRC packet loss event based on the control signal issued by the processor.

Continuing to take table 2 as an example, when the control signal received by the logic device and sent by the processor is 010100, the logic device controls the indicator lights corresponding to the network ports 2 and 4 to switch to the display mode corresponding to the CRC packet loss event according to the control signal, and the other indicator lights remain unchanged.

In one embodiment shown, the network device further includes a chip that can detect the status of a network port.

Specifically, the processor may receive an abnormal event reported when the chip detects an abnormal state of the network port, and determine whether the received abnormal event is an abnormal event corresponding to the abnormal state in which the CRC packet loss occurs at the network port; if yes, determining that the CRC packet loss event occurs on the network port.

For example, when the chip detects that a network port is abnormal, the chip reports the abnormal event to the CPU, and the CPU determines whether the abnormal event is a CRC packet loss abnormal event; if yes, determining that the CRC packet loss event occurs on the network port.

In addition, when the chip detects the state of the network port, the chip can directly judge whether the CRC packet loss event occurs to the network port. At this time, the processor determines that the network port has a CRC packet loss event according to the CRC packet loss event of the network port reported by the chip. Those skilled in the art can flexibly select a mode for determining whether the CRC packet loss event occurs on the network port according to needs, which is not limited in the present application.

It should be noted that the chip may include a PHY chip or a switch chip, and those skilled in the art may select the PHY chip or the switch chip according to needs, which is not limited in this application.

Further, when the processor determines that the abnormal event reported by the chip is a CRC packet loss event occurring at the network port, the control signal issued by the processor to the logic device may include an alarm signal corresponding to the CRC packet loss event occurring at the network port.

In addition, the chip can send lighting signals to the logic device based on the network port state. Therefore, when the logic device receives the warning signal and the lighting signal, the logic device needs to combine the warning signal and the lighting signal to generate a composite lighting signal for finally controlling the indicator lamp.

In one embodiment shown, the logic device receives a lighting signal sent by the chip based on the state of the network port; the logic device is combined with the lighting signal based on the warning signal corresponding to the CRC packet loss event to generate a composite lighting signal; and controlling the indicator lamp to switch to a display mode corresponding to the CRC packet loss event according to the composite lighting signal.

Referring to fig. 3, fig. 3 is a schematic diagram of an indicator light control scheme according to an exemplary embodiment of the present application.

As shown in fig. 3, the PHY chip or the switch chip may detect a state of the network port, and may transmit a lighting signal to the logic device based on the state of the network port; meanwhile, the PHY chip or the switch chip may report the detected abnormal event of the network port to the processor, and when the processor determines that the abnormal event is a CRC packet loss event, the processor issues an alarm signal corresponding to the CRC packet loss event to the logic device.

After receiving a lighting signal sent by the chip based on the state of the network port and an alarm signal issued by the processor based on a CRC (cyclic redundancy check) packet loss event, the logic device compounds the alarm signal with the lighting signal to generate a lighting compound signal, and controls the indicator lamp to switch to a display mode corresponding to the CRC packet loss event according to the compound lighting signal.

In one embodiment shown, the composite lighting signal is a parallel lighting signal.

It should be noted that, in order to be compatible with the PHY chip and the switch chip, the processor may issue the type of the lighting signal while issuing the alarm signal, so that the logic device determines whether the lighting signal source is the parallel lighting signal sent by the PHY chip or the serial lighting signal sent by the switch chip.

Specifically, when the logic device receives a parallel lighting signal sent by the PHY chip, the logic device directly outputs the parallel lighting signal without performing serial-to-parallel conversion processing; when the logic device receives the serial lighting signal transmitted by the switching chip, the serial lighting signal cannot simultaneously light a plurality of indicator lamps, and therefore, the serial lighting signal needs to be decoded and the parallel lighting signal needs to be generated through serial-to-parallel conversion.

For example, the lighting signal type may be represented by one bit, assuming that 0 represents the parallel lighting signal transmitted by the PHY chip and 1 represents the serial lighting signal transmitted by the switch chip. When the logic device determines that the lighting signal is a parallel lighting signal sent by the PHY chip, compounding the parallel lighting signal with the alarm signal; when the logic device determines that the lighting signal is the serial lighting signal sent by the exchange chip, the serial lighting signal is decoded, and then the parallel lighting signal obtained after decoding is combined with the alarm signal.

In one embodiment shown, the alert signal and the lighting signal include several fields; wherein, the fields respectively correspond to different network ports.

For example, the alarm signal and the lighting signal may be multi-bit data, and the number of bits corresponds to the number of the network ports, that is, the corresponding indicator lamps of the network ports are controlled by each bit of data. In this case, 0 is turned off and 1 is turned on.

Continuing with the example of tables 1 and 2, the alarm and lighting signals received by the logic device are as shown in table 3 below:

indicator light	1	2	3	4	5	6
							Alarm signal	0	1	0	1	0	0
Lighting signal	0	1	1	1	0	0

TABLE 3

As shown in table 3, there are 6 network interfaces for the network device, and 6 corresponding indicator lights. The indicator lights 1, 5, and 6 are turned off, the indicator lights 2, 3, and 4 are always on, and the CRC packet loss event occurs at the network ports 2 and 4.

The indication lamp is assumed to be a red and green double-color indication lamp, the indication lamp displays green according to the lighting signal, and displays red according to the warning signal. At this time, the indicator lamps 2 and 4 need to be switched to display red corresponding to the CRC packet loss event, and the chip still sends a lighting signal that the indicator lamps 2 and 4 display green to the logic device, but the indicator lamps can only display one color at the same time, and the display red is in conflict with the display green.

Therefore, the logic device needs to compound the alarm signal and the lighting signal to generate a compound lighting signal; and controlling the indicator lamp to switch to a display mode corresponding to the CRC packet loss event based on the composite lighting signal.

In one embodiment shown, the alarm signal may be inverted bitwise to generate an inverted code of the alarm signal; then, the inverse code of the alarm signal and the lighting signal are bitwise AND-ed to generate a composite lighting signal.

Through the above composite processing, the composite lighting signal finally obtained from the alarm signal and the lighting signal in table 3 is as shown in table 4 below:

indicator light	1	2	3	4	5	6
							Alarm signal	0	1	0	1	0	0
Anticode of alarm signal	1	0	1	0	1	1
							Lighting signal	0	1	1	1	0	0
Composite lighting signal	0	0	1	0	0	0

TABLE 4

At the moment, the alarm signal is inverted according to the bit to generate an inverted code of the alarm signal, and then the inverted code and the lighting signal are subjected to bit-to-bit combination, so that the control of the lighting signal on an indicator lamp corresponding to a network port with a CRC (cyclic redundancy check) packet loss event can be shielded.

For example, as shown in table 4, the lighting signals of the indicator lamps 2 and 4 are bitwise and-ed by the inverse code of the alarm signal of the indicator lamps 2 and 4, and finally the composite lighting signal is 0, which corresponds to the lighting signals of the indicator lamps 2 and 4 being masked, and the indicator lamp corresponding to the network port where the CRC packet loss event occurs cannot display green any more.

Continuing to take the red and green double-color indicator light as an example, the indicator light needs to be switched to red display corresponding to the CRC packet loss event, and the logic device can directly control the indicator light according to the alarm signal.

For example, as shown in table 4, when a CRC packet loss event occurs at the network ports 2 and 4, the corresponding indicator lamps 2 and 4 need to be switched to a red display corresponding to the CRC packet loss event, and then the indicator lamps 2 and 4 may display a red color according to the alarm signal.

The display modes of the red and green double-color indicator light shown above include a green mode and a red mode, wherein the green mode indicates that the network port is in a normal working state, the red mode indicates that the network port has CRC packet loss, and the indicator light is turned off to indicate that the network port is not in a working state.

The network port usually has a plurality of states, so that related personnel can know the current situation of the network port in more detail, and the display mode of the indicator light can be flexibly configured.

In one embodiment shown, the display modes include at least one or a combination of more of the following:

different colors displayed by the indicator lights;

different flashing frequencies displayed by the indicator light;

the lighting time displayed by the indicator lamp.

For example, if the indicator light can display two colors of red and green, two flashing frequencies of fast flashing and slow flashing, and two lighting durations of short lighting and long lighting, the indicator light can satisfy the indication of multiple states of the network port by combining the state types in the above 3.

In addition, for the convenience of distinction, a person skilled in the art may select a display mode in which a distinct distinction exists as a display mode to be switched by the indicator light, as needed, which is not limited in the present application.

When frequent CRC packet loss occurs on a network port, the network device may not work normally or even crash. Therefore, before the device is shipped out, the network port with a problem needs to be checked as soon as possible during testing, and when the device is actually used by a user, the CRC packet loss which occurs occasionally is within an acceptable range.

In order to meet both the testing requirement before the network equipment leaves the factory and the actual use requirement of a user, when the processor determines that a CRC (cyclic redundancy check) packet loss event occurs in the network port and sends an alarm signal to the logic device, an alarm mode can be sent. The logic device can control the indicator light to switch to different display modes according to different use scenes, so that CRC (cyclic redundancy check) packet loss events of the network ports can be indicated more flexibly.

In one embodiment shown, the processor may issue an alert mode to the logic device; the alarm mode comprises a test mode and a working mode.

When the network equipment is in the test mode, related personnel can know whether a CRC (cyclic redundancy check) packet loss event occurs to a network port according to the indicator lamp, and before the CRC packet loss event is not solved, the indicator lamp keeps the display mode of the CRC packet loss event unchanged;

for example, the test mode may be turned on when the network device is tested internally or ex-factory. At this time, once a CRC packet loss event occurs at the network port, the indicator light corresponding to the network port may be switched to a mode in which the red light is normally on, and the indicator light is always red unless the tester solves the packet loss problem or restarts the device.

In the test mode, the indicator lamp can remind a tester to solve the CRC packet loss event occurring at the corresponding network port as soon as possible by continuously displaying the alarm mode.

When the network equipment is in a working mode, although the indicator lamp still indicates the CRC packet loss state of the network port, in order to avoid causing panic of a user, when a CRC packet loss event occurs, the indicator lamp keeps the display mode of the CRC packet loss event unchanged only when the CRC packet loss event continuously exceeds a preset time length;

for example, the operational mode may be turned on when the network device is actually operating. At this time, once a CRC packet loss event occurs at the network port, the indicator light corresponding to the network port may be switched to the red display mode; meanwhile, the processor can judge whether the CRC packet loss event exists within a preset time threshold value all the time;

if the CRC packet loss event still exists, the indicator lamp continues to display red, and the indicator lamp continuously displays red, so that a user can be reminded that the CRC packet loss event occurring at the network port needs to be solved as soon as possible; and if the CRC packet loss event does not occur any more, the indicator light is switched from the display red color to the normal display mode.

By configuring different alarm modes, the network equipment can flexibly adapt to the requirements of different scenes.

Corresponding to the above method embodiments, the present specification also provides an embodiment of an indicator light control apparatus.
