Fig. 1 is a flowchart of a control method of an LLDP enabled state, which is provided in an embodiment of the application, and the method is applied to an LLDP enabled state monitoring thread created by a BMC, as shown in fig. 1, and the method includes:
s10: when the LLDP enabling state modification request is determined to be received and the network card is determined to meet the LLDP enabling state modification condition, a target interface is called to acquire modification request related information;
it should be noted that, the technical solution provided in the present application is applied to an LLDP enabled state monitoring thread created by a BMC, where the thread is configured to monitor whether to obtain an LLDP enabled state modification request of a user, and modify the LLDP enabled state according to the request of the user.
In an embodiment, when the user needs to modify the LLDP enabled state and the system does not install the LLDP client under the operating system, the LLDP enabled state modification request may be sent to the Web module in the BMC or to the Redfish through the browser, where the Redfish is a management standard based on HTTPs services. After the LLDP enabling state monitoring thread is established and the Web module or the Redfish receives the LLDP enabling state modification request of the user, judging whether the network card meets the modification condition of the LLDP enabling state, and if the network card meets the condition, calling a target interface to acquire the related information of the modification request.
When judging whether the network card meets the modification condition of the LLDP enabling state, the LLDP enabling state monitoring thread firstly acquires prestored network card related information from the EEPROM, wherein the network card related information at least comprises a network card manufacturer, a network card model and whether LLDP enabling state modification mark information is supported. And then establishing communication with the network card to acquire the current network card related information, judging whether the current network card related information is consistent with the prestored network card related information, and if so, determining that the network card meets the modification condition of the LLDP enabling state.
It is noted that the modification request related information is a result obtained by analyzing the LLDP enabling state modification request after the Web module or the Redfish obtains the LLDP enabling state modification request of the user, and the result is stored in the temporary file after the modification request related information is obtained by analyzing. The modification request related information comprises an LLDP enabled state modification instruction and a target network port MAC address.
It can be appreciated that the LLDP enabled state monitoring thread can directly obtain the modification request related information from the temporary file after determining that the LLDP enabled state modification request is received.
S11: determining a target network port according to the related information of the modification request;
further, after the LLDP enabled state monitoring thread obtains the information related to the modification request from the temporary file, the network port MAC address modified at this time can be determined, that is, the target network port MAC address can be determined. In the implementation, each network port on the network card is traversed in sequence, whether the network port traversed each time is a target network port MAC address is judged, the network port with the same MAC address as the target network port MAC address is used as a target network port, and the target network port is the network port needing LLDP enabling state modification.
S12: after the modification data packet is packaged, the modification data packet is sent to the network card, so that the network card sets the corresponding LLDP enabling state for the target network port.
After determining the target portal, the modified data packet is encapsulated, where the modified data packet may be an MCTP data packet or other types of data packets, which is not limited in this application. And sending the encapsulated modified data packet to the network card. After receiving the modification data packet, the network card analyzes the modification data packet to determine a target network port and an LLDP enabling state modification instruction, and then modifies the LLDP enabling state of the target network port based on the LLDP enabling state modification instruction.
The control method of the LLDP enabled state, provided by the embodiment of the application, is applied to an LLDP enabled state monitoring thread created by a BMC, and comprises the following steps: and when the LLDP enabling state modification request is determined to be received and the network card is determined to meet the LLDP enabling state modification condition, calling the target interface to acquire modification request related information, determining the target network port according to the modification request related information, and after the modification data packet is packaged, sending the modification data packet to the network card so that the network card sets the corresponding LLDP enabling state for the target network port. Therefore, according to the technical scheme provided by the application, the LLDP enabling state of the network port is modified in an out-of-band mode through the LLDP enabling state monitoring thread created by the BMC, an LLDP client is not required to be installed to operate under an operating system, the LLDP enabling state can be modified under a bare machine state, the LLDP function control diversity is increased, different requirements of users are met, and user experience is further improved.
In a specific embodiment, when a user needs to modify an LLDP enabled state, sending an LLDP enabled state modification instruction to a Web module or a Redfish in a BMC through a browser, and analyzing the received LLDP enabled state modification instruction by the Web module or the Redfish to obtain modification request related information, namely, obtaining the LLDP enabled state modification instruction and a target portal MAC address, and storing the modification request related information in a temporary file. Wherein, the LLDP enabled state modification instruction is used for modifying the LLDP enabled state of the network port, for example, the instruction is used for modifying the LLDP enabled state of the network port into open. And the target portal MAC address is used for determining the target portal which needs to be modified by the user from the portals.
It should be noted that, after performing the LLDP enable state modification once, the temporary file storing the information related to the modification request is deleted. Therefore, when determining whether the LLDP enabled state modification request is received, the LLDP enabled state monitoring thread determines that the LLDP enabled state modification request of the user is accepted by judging whether a temporary file for storing modification request related information exists.
According to the LLDP enabling state control method provided by the embodiment of the application, when the LLDP enabling state modification request is received, whether the LLDP enabling state modification request of a user is received is determined according to whether a temporary file for storing modification request related information exists. Therefore, the LLDP enabling state monitoring thread can determine whether a modification request to the LLDP enabling state of a user is received currently according to whether a temporary file exists or not, modify the LLDP enabling state according to a monitoring result, and further modify the LLDP enabling state by a bare metal machine, so that user experience is improved.
On the basis of the above embodiment, after the LLDP enabled state monitoring thread determines that the LLDP enabled state modification request of the user is received through whether the temporary file exists, it is required to determine whether the network card meets the LLDP enabled state modification condition. Therefore, as a preferred embodiment, determining that the network card satisfies the LLDP-enabled state modification condition includes:
acquiring prestored network card related information from the EEPROM; the network card related information at least comprises a network card manufacturer, a network card model and whether LLDP enabling state modification mark information is supported;
after establishing communication with the network card, acquiring current network card related information;
judging whether the prestored network card related information is consistent with the current network card related information;
if yes, determining whether the network card supports LLDP enabling state modification, if yes, determining that the network card meets LLDP enabling state modification conditions, and if not, recording log information that the network card does not support LLDP enabling state modification;
if the current network card related information is inconsistent with the prestored network card related information, recording the log information of the inconsistent current network card related information.
It can be understood that, when the network card leaves the factory, the network card related information such as the network card manufacturer and the network card model is stored in the EEPROM, so when judging whether the current network card meets the LLDP enabling state modification condition, the pre-stored network card related information is acquired from the EEPPROM through the I2C link, communication is established with the current network card, and then the current network card related information is acquired.
It should be noted that, the network card related information at least includes a network card manufacturer, a network card model, and whether to support LLDP enabled status modification flag information, where whether to support LLDP enabled status flag information may be a number, may also be english, or may also be other symbols, which is not limited in this application.
And comparing whether the prestored network card related information is consistent with the current network card related information, if so, further determining whether the network card supports LLDP enabling state modification according to the network card related information, and if so, determining that the network card meets the LLDP enabling state modification condition.
If the prestored network card related information is inconsistent with the current network card related information or the network card does not support LLDP enabling state modification according to the network card related information, determining that the network card does not meet the LLDP enabling state modification condition, and storing the related information of the unsatisfied condition in a log mode at the moment.
According to the LLDP enabling state control method, when the network card is determined to meet the LLDP enabling state modification condition, whether the pre-stored network card related information in the EEPROM is consistent with the current network card related information is determined, after the LLDP enabling state modification condition is determined to be met, the LLDP enabling state is modified, modification reliability is improved, and user experience is further improved.
It can be understood that the network cards of different manufacturers have different corresponding calling interfaces, so when the target interface is called to obtain the relevant information of the modification request on the basis of the embodiment, the target interface needs to be determined according to the vendor information of the network card in the relevant information of the network card, and then the relevant information of the modification request is obtained from the temporary file through the target interface.
According to the LLDP enabling state control method, when the target interface is called to acquire the modification request related information, the target interface is determined according to a network card manufacturer, the modification request related information is acquired from the temporary file through the target interface, the modification request related information in the temporary file is accurately and rapidly acquired according to the interface corresponding to the network card manufacturer, and LLDP enabling state modification efficiency and accuracy are improved.
In a specific embodiment, the network card includes a plurality of ports, when performing the LLDP enabling state modification of a certain port, it is necessary to determine a target port according to the modification request related information, and modify the LLDP enabling state of the target network card, so as a preferred embodiment, determining the target port according to the modification request related information includes:
traversing MAC addresses of all network ports of the network card in sequence;
judging whether the network port MAC address is the same as the target network port MAC address in the temporary file or not by traversing one network port MAC address every time;
if the network ports are the same, determining that the network ports with the same MAC address are target network ports.
In the implementation, each network port of the network card is traversed in turn to acquire the MAC address of each network port, and each time one network port MAC address is acquired, the MAC address is compared with the target network port MAC address acquired in the temporary file, and the network port with the same MAC address as the target network port MAC address is used as the target network port, namely the network port of which the LLDP enabling state is to be modified.
Of course, if the acquired MAC address is different from the MAC address of the target port, the next MAC address is acquired and compared until the target port identical to the MAC address of the target port is found. If all the network ports are found, transmitting a prompt signal to the client.
According to the LLDP enabling state control method provided by the embodiment of the application, whether the MAC address of each network port of the network card is the same as the target MAC address in the temporary file is compared to determine the target network port, so that the LLDP enabling state of the target network port is accurately modified.
It can be understood that if it is determined that the network card does not support the LLDP enabled state modification according to the network card related information, the corresponding log information needs to be stored, however, in order to avoid repeatedly recording multiple pieces of identical log information, excessive resources are occupied, and as a preferred embodiment, the technical scheme provided by the present application further includes:
judging whether the recorded log information quantity of the network card which does not support LLDP enabling state modification exceeds a preset value or not;
if the stored time exceeds the preset value, the log information with the earlier time is cleared according to the stored time.
The LLDP enabling state monitoring thread monitors the stored log information in real time, judges whether the recorded quantity of the log information which does not support LLDP enabling state modification exceeds a preset value, and deletes the log information stored earlier according to the stored time if the quantity of the log information exceeds the preset value, so that the quantity of the log information is prevented from exceeding the preset value. For example, if the preset value is 3, when the number of log information recorded in the network card that does not support LLDP enabled state modification is 4, then deleting one log information recorded earlier.
According to the LLDP enabling state control method, when the recorded network card is determined that the quantity of log information which does not support LLDP enabling state modification exceeds a preset value, log information with earlier storage time is cleared according to the storage time. Therefore, based on the log anti-collision strategy, resources are saved, and the reliability of LLDP enabled state control is improved.
In implementation, after the network card receives the modification data packet sent by the LLDP enabled state monitoring thread, the modification data packet is parsed to determine an LLDP enabled state modification instruction, and the LLDP enabled state of the target portal is set according to the LLDP enabled state modification instruction. For example, when the LLDP enable state modification command is to turn on the LLDP, the network card turns on the LLDP enable state of the target network card after parsing the modification data packet.
According to the LLDP enabling state control method, based on the monitoring of the LLDP enabling state monitoring thread on the user request, the corresponding modification data packet is sent to the network card based on the LLDP enabling state modification request, and therefore the LLDP enabling state of the network card is modified. Therefore, the LLDP enabling state of the network port is modified in an out-of-band mode, an LLDP client is not required to be installed under an operating system to operate, LLDP function control diversity is increased, different requirements of users are met, and user experience is further improved.
In the above embodiments, the control method of the LLDP enabled state is described in detail, and the present application further provides a corresponding embodiment of the control device of the LLDP enabled state. It should be noted that the present application describes an embodiment of the device portion from two angles, one based on the angle of the functional module and the other based on the angle of the hardware structure.
