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

The ports of the network device are usually provided with corresponding indicator lights for displaying the status of the respective ports. The indicator lights are usually arranged around the ports of the network equipment, so that a user can conveniently determine the state of the corresponding port by observing the indicator lights on the panel of the network equipment. For example, a corresponding indicator light is usually set around a port of the switch to indicate whether the corresponding port is in a normal connection state. The user can confirm the operating condition of each port through observing the pilot lamp of corresponding port to carry out equipment maintenance to the switch.
In some special use environments, the user cannot be in direct proximity to the network device. For example, in an environment such as an unmanned area, deep water, and strong radiation, a user is not easy to approach the network device to acquire status information of each port of the network device. One solution is that the network device sends the status information of each port to the network management terminal through the network, and the user remotely checks the status information of each port of the network device by using the network management terminal. For example, in a network device set in an unmanned area, status information of each port on the device is sent to a PC terminal through a network, and a user views the status of each port on the network device by using the PC. However, this method depends on the port status information of the network transmission device, and once the network fails, the status information of each port on the network device cannot be obtained, which is not favorable for the user to maintain and monitor the device.

Within the indicator light control device, a programmable logic device 101 is connected to a relay module 102. The relay module 102 is connected to the indicator lights via a remote cable. The relay module 102 may control the on-off state of the ac circuit, for example, control the on-off state of an indicator light in the ac circuit, through the general input/output pin of the dc low voltage. In addition, the relay module 102 in this embodiment can control the remote indicator light through a long-distance cable. The remote display mode of the indicator lamp does not rely on a network, but controls the indicator lamp by a long-distance cable, and the circuit formed by the cable is more reliable to control the indicator lamp.
In this embodiment, the programmable logic device 101 is specifically configured to: receiving a lighting waveform sent by the network equipment; analyzing the lighting waveform to obtain port state information of a target port on the network equipment; and outputting corresponding level according to the port state information.
The network device can generate the corresponding lighting waveform from the state information of each port in the device according to the preset waveform definition, and send the lighting waveform to the programmable logic device 101 in the indicator light control device through the general input/output pin. The waveform definition includes a correspondence between port state information of each port in the network device and a waveform, and detailed description is given later. The network device may generate a corresponding waveform from the port state information of the port according to the correspondence, as the lighting waveform.
The programmable logic device 101 receives the lighting waveform sent by the network device through the general input/output pin, and converts the lighting waveform into port state information of a target port on the network device according to a corresponding relationship in the waveform definition.
In one example, the programmable logic device 101, when configured to receive a lighting waveform sent by the network device, includes: if the lighting waveform is judged to be the starting waveform, receiving the lighting waveform; the start waveform is a waveform defined in a preset waveform definition.
Taking the example of two general purpose input/output pins provided on the programmable logic device 101 in fig. 1 as an example, fig. 2 shows a lighting waveform including a clock waveform C L K and a DATA waveform data.a Start waveform may be defined in advance in the waveform definition, for example, the Start waveform is composed of a high C L K waveform and a low DATA waveform, and the Start waveform is a Start waveform since the Start waveform is a high C L K waveform and a low DATA waveform, the programmable logic device 101 receives the Start waveform and determines that it is the Start waveform, and then receives the lighting waveform.
In another example, the programmable logic device 101, when configured to receive a lighting waveform transmitted by the network device, includes: if the lighting waveform is judged to be the ending waveform, stopping receiving the lighting waveform; the end waveform is a waveform defined in a preset waveform definition.
In the above example, the End waveform is also defined in advance in the waveform definition, and the programmable logic device 101 recognizes the waveform as a condition for stopping reception of the lighting waveform, and the lighting waveform shown in fig. 2 is described as follows.
In another example, the port state information includes at least any one of a negotiation state, a rate state and a data transceiving state, wherein the negotiation state is used for indicating that the port of the target port negotiates L ink state, the rate state indicates that the rate of the target port, such as the rate values including 10Mbit/s, 100Mbit/s, 1000Mbit/s and 10Gbit/s, and the data transceiving state indicates that the data transceiving Active state of the target port, that is, whether the port is currently transceiving data traffic or not.
Fig. 3 illustrates a schematic diagram of an indicator, where each port corresponds to one relay submodule for controlling the indicator corresponding to the port to display, and the programmable logic device specifically selects CP L d, where each port corresponds to multiple indicators, including an indicator corresponding to a negotiation state of the port, i.e., a link indicator, an indicator corresponding to a rate state of the port, i.e., a 10Mbit/s indicator, a 100Mbit/s indicator, a 1000Mbit/s indicator, and a 10Gbit/s indicator, and an indicator corresponding to a data transceiving state of the port, i.e., an Active indicator.
The programmable logic device 101 analyzes the lighting waveform to obtain port state information of a target port on the network device, and then outputs a corresponding level to the relay module 102 according to the port state information. And the relay module 102 receives the level sent by the programmable logic device 101, and controls an indicator lamp corresponding to a target port on the network equipment to perform remote display through a circuit formed by long-distance cables. The cable is more reliable in the long-distance transmission process compared with the network long-distance transmission, so the indicator lamp device provided by the embodiment can more reliably remotely display the port state of the target port on the network equipment.
The port 1 is taken as an example in conjunction with the connection relationship between the relay module 102 and the indicator light shown in fig. 3. If the programmable logic device 101 analyzes the lighting waveform, the port state information of the port 1 is obtained: the negotiation state is a link state, the rate state is 100Mbit/s, and the data transceiving state is an Active state. The programmable logic device 101 generates corresponding levels according to the Port state information and outputs the levels to the Port-1 relay submodule, and the Port-1 relay submodule lights a link indicator light, a 100Mbit/s indicator light and an Active indicator light according to the corresponding levels. In this embodiment, the relay module 102 includes a plurality of relay sub-modules, and in other realizable manners, the control of all the indicator lights may be realized by one complete relay module, and the specific form of the relay module is not limited in this embodiment.
In this embodiment, the programmable logic device 101 in the indicator control apparatus may receive a lighting waveform sent by the network device through the extended general input/output pin, and output a corresponding level according to the analyzed port state information, so that the relay module 102 utilizes the remote cable to remotely display the indicator corresponding to the target port on the network device according to the corresponding level. The port state information of the network equipment is not transmitted by the network any longer, the indicator lamp of the corresponding target port is directly controlled by the remote cable to carry out remote display, the acquisition of the port state information of the target port on the network equipment cannot be influenced by network faults, and the cable connection is more reliable than the network connection.
This specification also provides a network device, the device comprising: at least one network port, a processor, and a general purpose input output pin. Illustratively, fig. 4 shows a network device, wherein the chip of the network device includes n ports: port-1, Port-2. Port-n; two general input and output pins are arranged in a CPU of the network equipment: pin 3 and pin 4.
The processor is specifically configured to: acquiring port state information of a network port; generating a lighting waveform corresponding to the port state information according to a preset waveform definition; the waveform definition includes a correspondence between port state information of the network port and the waveform.
Specifically, the processor in the network device may traverse each network port on the query chip, obtain state information of each network port, and generate corresponding lighting waveforms from the port state information of the network port according to a correspondence between the port state information of the network port and the waveforms in the preset waveform definition. The time when the processor of the network device traverses the query network port may be a preset trigger condition, for example, the processor queries the port state information of the target port at regular time intervals, or at a preset fixed time, the processor queries the port state information of the target port. The present specification does not limit the specific trigger conditions.
In one example, the waveform definition in the network device is preset in the form of software, and the correspondence between the port state information of the network port and the waveform is determined. When the indicator light control device provided in this specification is used to perform remote indicator light display on a network port of a network device, a waveform definition needs to be preset in the network device, that is, a correspondence between port state information of the network port in the network device and a waveform is determined. In this way, the processor of the network device can convert the port state information of each port into a corresponding lighting waveform by using the correspondence relationship in the waveform definition. Correspondingly, the programmable logic device can convert the lighting waveform into the port state information of each corresponding port according to the corresponding relation in the waveform definition, and then the relay module is used for remotely controlling the display of the corresponding indicator lamp.
In the related art, the waveform definition of the chip is already determined before the chip leaves the factory, and the port status indicator lamp display method can only depend on the fixed waveform definition. The network device provided by the specification can use software to define waveform definition, does not depend on the implementation of network hardware or network chips, and can be fully compatible with various network product hardware, so that unified standard is achieved.
The lighting waveform shown in fig. 2 corresponds to the indicator light shown in fig. 3, and respectively shows a start waveform, a waveform corresponding to port state information in each network port and an end waveform, and a processor in the network device can respectively output a C L K waveform and a DATA waveform through two general input and output pins, such as two GPIO pins, and a C L K waveform and a DATA waveform are respectively received by the GPIO pin corresponding to the programmable logic device.
In this embodiment, the waveform definition may be set in advance for the network device by software, where a high C L K waveform and a low DATA waveform are defined as Start waveforms, such as the Start waveform shown in fig. 2, and a low C L K waveform and a low DATA waveform are defined as End waveforms, such as the End waveform shown in fig. 2.
For example, in the lighting waveform corresponding to port 1, waveform 1(C L K waveform 1+ DATA waveform 1) corresponds to the first indicator light of port 1, i.e., to the link indicator light, waveform 2(C L K waveform 2+ DATA waveform 2) corresponds to the second indicator light of port 1, i.e., to the 10Mbit/s indicator light, and so on, in this embodiment, the switching state of the corresponding indicator light is also defined using the waveform 1, i.e., waveform 1 is high level, i.e., it means that the waveform corresponding to DATA 1 is low level, i.e., it corresponds to the DATA 2.
After the lighting waveform is customized by software, the corresponding relation between the port state information of the network port in the network equipment and the waveform is obtained. And, the corresponding relation between each indicator lamp and the lighting waveform in each network port is determined.
The lighting waveform illustrated in fig. 2 can be interpreted as follows according to the set waveform definition: the port state information of network port 1 is: the link state is successfully negotiated, the rate size is 100Mbit/s, and data is being transmitted and received; the port state information of network port 2 is: the link state is successfully negotiated, the rate size is 1000Mbit/s and data is being transmitted and received; the port state information for network port n is: negotiation link status fails, the rate size is 0Mbit/s and no data is transmitted or received.
And the processor of the network equipment generates corresponding lighting waveforms according to the waveform definitions from the port state information of each network port, and sends the lighting waveforms to the programmable logic device in the indicator light control device through the universal input/output pins. In the embodiment, only the universal input and output pins need to be extended on the network equipment, no redundant bus and circuit are needed, plug and play can be achieved, and any software configuration or hardware debugging is not needed.
The programmable logic device in the indicating lamp control device reads the port state information of the corresponding network port according to the waveform definition, and the corresponding indicating lamp is lightened by using the relay module. Taking the lighting waveform shown in fig. 2 as an example, the relay module lights a remote indicator lamp through a circuit composed of a long-distance cable. In the pilot lamp that port 1 corresponds, light respectively: link indicator light, 100Mbit/s indicator light and Active indicator light; in the pilot lamp that port 2 corresponds, light respectively: link indicator light, 1000Mbit/s indicator light and Active indicator light; the indicator lights corresponding to the port n are all lighted.
