Embodiment
PSE is a hardware component, does not contain operating software, and the initialization operation of PSE is that software is initiatively to its operation.The network equipment that is built-in with PSE behind software restarting, just can't know restart before PSE whether power-up initializing accomplish.Can only realize through alternate manner.Such as, before restarting with the operation note of PSE in non-volatile memory medium, remove to obtain the work at present state of PSE after restarting again.But the problem of bringing is: as long as the network equipment power-up initializing that is built-in with PSE once; The power down once more of this network equipment, electrifying startup; Its built-in PSE is according to the operation note in the non-volatile memory medium, and PSE can not reinitialize, also just can't operate as normal.It is thus clear that; Should handle the network equipment that is built-in with PSE when software reset or software anomaly are restarted; Its built-in PSE can not repeat initialization; Can guarantee that again this network equipment its built-in PSE when powering on carries out initialization, the operation note of the PSE before only restarting by storage is not enough.
In order to solve the problems referred to above that prior art exists, the embodiment of the invention provides a kind of controlling schemes of restarting to the network equipment that is built-in with PSE, and this scheme is mainly restarted type through PSE is set; And restart type when being the cold restart type as PSE, just PSE is carried out initial configuration, and as PSE when to restart type be non-cold restart type; PSE is not carried out initial configuration; Thereby guaranteed that when network equipment cold restart, PSE also carries out initial configuration, and when the non-cold restart of the network equipment; PSE does not carry out initial configuration, with the power receiving equipment power down of avoiding hanging under this network equipment.Said PSE is restarted type and can be dynamically arranged according to the current type of restarting of the network equipment.
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
In the embodiment of the invention; When the network equipment that is built-in with PSE is restarted; Whether needs carry out initial configuration can to judge its built-in PSE according to two signs, are being judged as need not carry out initial configuration the time, then do not carry out the initial configuration process of PSE; Thereby avoid power down, the power up of PSE, and then avoid power down, the power up of power receiving equipment.
Wherein, two related signs, one can be described as equipment and restarts type identification, and another can be described as PSE and restarts type identification.Wherein:
Equipment is restarted type identification, is used to identify the type of restarting of the network equipment that is built-in with PSE.This sign can be when this network equipment is restarted be restarted type setting by device hardware according to current.Can be implemented at present the type of restarting that writes down this network equipment in the non-volatile memory medium, correlation technique is a lot, gives an example no longer one by one at this.Wherein, how restarting type identification by device hardware according to recording equipment, is not the emphasis that the embodiment of the invention is paid close attention to, and does not receive restriction of the present invention yet.Usually, equipment is restarted type and can be comprised following 3 kinds:
(1) cold restart starts again after promptly being built-in with the network appliance power-down of PSE;
(2) software reset is restarted, and promptly restarts according to software reboot command execution.The user can control the network equipment that is built-in with PSE through order line restarts, and in the restarting process of this type, network equipment run duration does not cut off the power supply;
(3) software anomaly is restarted, and is owing to the running software mistake causes restarting automatically, and in the restarting process of this type, the network equipment run duration that is built-in with PSE does not cut off the power supply.
Wherein, the software reset is restarted to restart with software anomaly and is belonged to non-cold restart.
PSE is restarted type identification, and this sign can perhaps be upgraded behind network equipment cold restart according to the type setting of restarting of this network equipment when the network equipment that is built-in with PSE is restarted.PSE is restarted type can comprise following two kinds:
(1) PSE hot restart, expression PSE moves, and does not need to carry out initial configuration again;
(2) PSE cold restart, expression PSE have just powered on and operation for the first time, need carry out initial configuration.
For the purpose of data security, more than two kinds of signs can be kept on the non-volatile memory medium, like FLASH (flash memory).
Be built-in with the network equipment of PSE, its software startup can divide two stages to carry out: boot stage and application program stage.Accomplish the basic initialization of this network equipment veneer in the boot stage, can load, upgrade applications etc.; Carry out the configuration of all functions of this network equipment in the application program stage, as for switch device, realizing all functions of Ethernet switch.
Fig. 2 shows the restarting process of the network equipment that is built-in with PSE that the embodiment of the invention provides; In this process; The parts (like program) that are used to control restarting process can be restarted type identification and PSE according to equipment and restarted type identification and determine whether that needs carry out initial configuration to PSE; And only when needs carry out initial configuration, just PSE is carried out the corresponding configuration operation, thereby minimizing equipment is restarted the influence to power receiving equipment.
As shown in Figure 2, in step 201, before the network equipment that is built-in with PSE was restarted, its hardware can be according to restarting type, and equipment is restarted type identification and is set to corresponding ident value in non-volatile memory medium.As, if restarting type is power-down rebooting, then equipment is restarted the ident value that type identification is set to the cold restart type; If to restart type is that the software reset is restarted, then equipment is restarted type identification and is set to the ident value that the software reset is restarted type; If to restart type is that software anomaly is restarted, then equipment is restarted type identification and is set to the ident value that software anomaly is restarted type.
The network equipment is restarted the back and is got into the software startup stage, and the software startup stage is divided into boot stage (step 202) and application program stage (step 203).
In boot stage (step 202), readout equipment is restarted type identification from non-volatile memory medium, the PSE in this non-volatile memory medium is restarted type identification carry out relative set, comprising:
If it is the cold restart type identification that equipment is restarted type identification, then show the network equipment current be cold restart, and cold restart process need PSE carries out initial configuration, at this moment, PSE is restarted type identification forces to be set to PSE cold restart type identification value;
If it is not cold restart type identification (software reset restart type identification or software anomaly is restarted type identification) in this way that equipment is restarted type identification; Then show the network equipment current be not cold restart; But not the cold restart process does not need PSE to carry out initial configuration; At this moment, keep PSE to restart type identification value constant (current PSE is restarted the ident value that the type identification value is the hot restart type).
In the application program stage (step 203); Restart type identification according to PSE and judge whether that needs carry out the PSE initial configuration; Then carry out the PSE initial configuration if desired; Can cause PSE power down, power up this moment, corresponding, and the PD equipment that this network equipment descended to hang also will experience power down, power up; If need not carry out the PSE initial configuration, then can not cause PSE power down, power up, corresponding, this network equipment institute down extension PD equipment also not can so and power down.In addition; In that the network equipment is current when being cold restart; After carrying out PSE initialization setting, also will be forced the PSE that is set to the cold restart type restarts type identification and is set to the hot restart type; So that when non-cold restart (restarting or software anomaly is restarted like the software reset) takes place in subsequent network device; Can the PSE in the non-volatile memory medium not restarted type and be revised as cold restart, be the hot restart type identification but restart type identification according to this PSE in the non-volatile memory medium, PSE do not carried out initial configuration.
Concrete, the application program stage can comprise: PSE configuration phase (step 2031) and PSE are restarted type identification the stage (step 2032) are set.
At PSE configuration phase (step 2031), from non-volatile memory medium, read PSE and restart type identification, if this is designated PSE cold restart type identification, then PSE is carried out initial configuration; If the PSE type identification is a PSE hot restart type identification, then PSE is not carried out initial configuration, but as required, can carry out other operation, as read PSE information, or further carry out relative set etc. according to the PSE information that reads.
Restart type identification at PSE the stage (step 2032) is set, PSE is restarted type identification and is set to the hot restart type identification.Certainly, if restart for the software reset or software anomaly is restarted by type for current the restarting of the network equipment, then to restart type identification be the hot restart type identification just to PSE, and can not carry out this setting operation this moment.
Need to prove that flow process shown in Figure 2 only shows with whether and need carry out initial configuration and carry out the step of handled according to judged result PSE, the required step of other in the restarting process can realize according to current mechanism.
Three kinds of basic operational modes below in conjunction with the network equipment that is built-in with PSE are described in detail above-mentioned flow process.
Operational mode scene one: described the network equipment and started from power on, to the start-up course in experience boot stage, application program stage.
Before being built-in with the network equipment electrifying startup of PSE, the equipment that writes down in the non-volatile memory medium is restarted type identification and is set to the cold restart type identification.Get into boot after the stage, force to be provided with PSE according to the cold restart type identification of the network equipment and restart and be designated the cold restart type identification.Get into application program after the stage; Because it is PSE cold restart type identification that current PSE is restarted type identification; Therefore PSE is carried out initial configuration; Begin power devices, and PSE restarts type identification and be set to the hot restart type identification, reset in order to subsequent software and restart or software anomaly uses when restarting PD.
Operational mode scene two: described when this network equipment that is built-in with PSE is restarted because of software reset or software anomaly, the network equipment does not get into the boot stage and directly gets into the restarting process in application program stage.
In the process of the normal operation of equipment, when restarting or restarting, directly get into the application program stage because of software anomaly according to order line.At the PSE in application program stage configuration phase since PSE to restart type be hot restart (with reference to the description of operational mode one), so PSE can not carried out initial configuration, therefore the process that power down powers on can not take place in the power receiving equipment that this network equipment is hung down.
Operational mode scene three: described when this network equipment that is built-in with PSE is restarted because of software reset or software anomaly the restarting process in network equipment experience boot stage and application program stage.
Similar with the scene of above-mentioned operational mode two; In the network equipment normal course of operation; When restarting or restarting because of software anomaly according to order line, the network equipment at first gets into the boot stage (as forcing the network equipment to get into the boot stage through the shortcut of ctrl+B).Get into boot after the stage; Because it is non-cold restart type identification (restarting or software anomaly is restarted like the software reset) that the equipment that writes down in the non-volatile memory medium is restarted type identification, then keeps the PSE in this non-volatile memory medium to restart type identification constant (it is the hot restart type identification that this PSE is restarted type identification).After getting into the PSE configuration phase in application program stage, because PSE restarts type and remain the hot restart type, so PSE can not carried out initial configuration, and the power receiving equipment that this network equipment is hung down also therefore the process that power down powers on can not take place.
Can find out that through above description the network equipment that is built-in with PSE powers on when restarting for the first time, PSE powers on for the first time, can carry out initial configuration first, and after the PSE operate as normal, following extension power receiving equipment begins the operation that normally powers on.Afterwards, if the network equipment does not have power down, no matter be that the reboot order is restarted, or software anomaly restart, PSE will no longer repeat initial configuration, and power receiving equipment also will work on power always.
Based on identical technical conceive, the embodiment of the invention also provides a kind of POE equipment to restart control device, and this device can be arranged at the network equipment that is built-in with PSE, and this device can be realized through software mode, and can be applicable to above-mentioned flow process.
As shown in Figure 3, this POE equipment is restarted control device and can be comprised: first processing module 301, second processing module 302, and memory module 303, wherein:
In the said apparatus, first processing module 301, that also can work as the network equipment that the vectoring phase in said network equipment restarting process reads restarts type when being non-cold restart, and keeping the type of restarting of the PSE of record in the memory module 303 is non-cold restart; Second processing module 302, also can work as PSE that the application program stage in restarting process reads to restart type be non-cold restart the time, built-in said PSE is not carried out initial configuration.
In the said apparatus; Second processing module 302; Also can when the said network equipment is restarted, directly get into application program during the stage at restarting process, reading and keeping the type of restarting of the PSE of record in the memory module 303 is non-cold restart type; And be non-cold restart type according to the type of restarting of said PSE, built-in said PSE is not carried out the initialization setting.
In sum; Use the operation information of non-volatile memory medium recording equipment in the embodiment of the invention; Simultaneously carry out handled, thereby guaranteed the initialization first that PSE powers on, the repetition initialization when having avoided software restarting again in the different phase of the network equipment.
Through the description of above execution mode, those skilled in the art can be well understood to the present invention and can realize by the mode that software adds essential general hardware platform, can certainly pass through hardware, but the former is better execution mode under a lot of situation.Based on such understanding; The part that technical scheme of the present invention contributes to prior art in essence in other words can be come out with the embodied of software product; This computer software product is stored in the storage medium; Comprise some instructions with so that computer equipment (can be personal computer, server, perhaps core net node equipment etc.) carry out the described method of each embodiment of the present invention.
More than disclosedly be merely several specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
