Technical Field
The present application relates to the field of computer technologies, and in particular, to an information updating method, apparatus, device, and readable storage medium.
Background
Currently, for each terminal under a three-layer switch, the MAC address of the network-accessing terminal can be obtained from a DHCP broadcast message or from an ARP table of the switch. The method for acquiring the MAC address from the DHCP broadcast message has the technical problem of inaccuracy, namely, when a plurality of DHCP servers exist in a network, the MAC address is acquired through the DHCP broadcast message. The MAC address is obtained from the ARP table, and the ARP table needs to be requested from the switch in time, which may cause the switch to have a large pressure and affect the normal transmission of the network data by the switch.
Therefore, how to improve the accuracy of acquiring IP and MAC information while avoiding the switch stress is a problem to be solved by those skilled in the art.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, the MAC address is acquired from the DHCP broadcast message, the DHCP request message needs to be analyzed, the data packet needs to be disassembled according to the DHCP protocol format for analyzing the DHCP broadcast message, the unpacking process is complex, mirror image flow operation is needed, and the overall efficiency is low. And when a plurality of DHCP servers exist in the network, the technical problem of inaccuracy exists in obtaining the MAC address through the DHCP broadcast message. The MAC address is obtained from the ARP table, and the ARP table needs to be requested from the switch in time, which may cause the switch to have a large pressure and affect the normal transmission of the network data by the switch. Therefore, the information updating scheme is provided, and the obtaining efficiency and accuracy of the IP and MAC information can be improved.
Referring to fig. 1, an embodiment of the present application discloses an information updating method, which is applied to a DHCP server, and the method includes:
s101, communication connection is established with a server.
Wherein, the server may be: the server side can count the latest corresponding relation between the IP and the MAC so as to inquire and call other functions or services. The server may be a three-layer network switching device.
S102, when the preset condition is met, based on the current working log in the DHCP server, the log related content is sent to the server, so that the server updates the corresponding relation between the IP and the MAC based on the log related content.
The log related content sent by the DHCP server to the server may be: the total content of the current working log in the DHCP server may also be a log change content generated between the current time and the previous sending time, or a content obtained after analyzing the current working log and representing the latest correspondence between the IP and the MAC. Similarly, the content of the correspondence between IP and MAC may be the content of the latest correspondence between IP and MAC in the whole amount, or the content of the correspondence between IP and MAC changed from the last time. The specific information in the work log recorded by the DHCP server may include: the identification information of the network access device and the MAC address of the network access device may also include: IP addresses are assigned time stamps, etc. To facilitate subsequent utilization of the IP-MAC correspondence, the present embodiment collects the latest IP-MAC correspondence using the server (any computer device).
It should be noted that, the DHCP server is connected to the three-layer network switch device, and after the DHCP server allocates an IP address to the network access device, the DHCP server records the IP allocation information of the network access device, and then obtains a working log of the DHCP server. When a DHCP server allocates an IP address to a network access device, the DHCP server records IP allocation information corresponding to the device. That is, the DHCP server is responsible for allocating IP addresses to the respective network-accessing devices connected to the three-layer network switching device. Specifically, fig. 2 is a schematic diagram of a DHCP server, a three-layer network switch device, and connections among network access devices. In fig. 2, a three-layer switch is a three-layer network switching device.
The IP allocation information recorded for one network access device may specifically include: the identifier of the network access device, the device name of the network access device, the IP address assigned to the network access device, the MAC address of the network access device, the IP address assignment timestamp, and the like. The identification information of the network access device may be: an identifier of the network-accessing device, a device name of the network-accessing device, or an IP address assigned to the network-accessing device. In a specific embodiment, the IP allocation information of the network access device may be stored in a preset storage path. That is, the work log of the DHCP server is fixedly stored in the preset storage path of the DHCP server.
It should be noted that, the process of allocating an IP address to a network access device by the DHCP server may refer to the related art. In a specific embodiment, allocating an IP address to a network access device includes: receiving a DHCP request packet sent by the network access equipment, and returning an allocable target IP address to the network access equipment based on the DHCP request packet; and receiving an IP address use request sent by the network access equipment, and returning a confirmation message to the network access equipment based on the IP address use request so as to distribute the target IP address to the network access equipment. The network access device can use the target IP address to carry out networking.
In one embodiment, the preset conditions are: the working log in the DHCP server changes. When the working log in the DHCP server changes, the preset condition is considered to be met, and therefore log related content is sent to the server based on the current working log in the DHCP server, so that the server updates the corresponding relation between the IP and the MAC based on the log related content. On the contrary, if the working log in the DHCP server is not changed, the preset condition is considered not to be met, so that no step is executed, and the working log in the DHCP server is continuously waited for changing. The mode that once the working log changes can lead the service end to update the corresponding relation between the IP and the MAC in time, and further improve the accuracy of the corresponding relation between the stored IP and the MAC.
In addition, specifically, whether the work log in the DHCP server changes or not is determined, and there are two ways, one is to actively monitor the change of the work log in the DHCP server; and the other is to passively receive the notification information sent by the DHCP server for indicating the change of the work log. How to implement the method can be determined according to actual scenes.
In particular, the embodiment may be implemented by deploying relevant components (such as the log collection component in fig. 2) in the DHCP server. In a specific implementation manner, the embodiment is implemented by a component with a log collection function deployed in a DHCP server. The components with the log collection function can be realized through logstack, nxlog, filebeat and the like. Accordingly, the component deployed in the DHCP server may actively monitor changes of the working log in the DHCP server to determine whether the preset condition is met, and may also passively receive notification information sent by the DHCP server to indicate the change of the working log to determine whether the preset condition is met.
It can be seen that, in this embodiment, the latest correspondence between the IP and the MAC can be obtained from the working log in the DHCP server. Since the DHCP server generally performs only DHCP-related services as an IP resource allocation and management master, it has sufficient resources to transmit its own work log to the server. Meanwhile, the DHCP server is a recording source of the corresponding relation between the IP and the MAC, so that when meeting the preset condition, the DHCP server sends the log related content of the current working log of the DHCP server to the server, and the server can acquire one hand of data of the corresponding relation between the IP and the MAC in time, so that the accuracy of the corresponding relation between the IP and the MAC determined by the server is guaranteed. Therefore, the proposal does not need to request the ARP table from the switch and disassemble the message, and can improve the information updating accuracy of the corresponding relation between the IP and the MAC without increasing the pressure of the switch.
Referring to fig. 3, an embodiment of the present application discloses another information updating method, which is applied to a server, and the method includes:
s301, communication connection is established with the DHCP server.
S302, the log related content sent by the DHCP server is obtained.
S303, updating the corresponding relation between the IP and the MAC based on the log related content.
In a specific embodiment, updating the correspondence between the IP and the MAC based on the log-related content includes: acquiring log information recorded with the corresponding relation between the IP and the MAC from the log related content; determining the latest corresponding relation between the IP and the MAC based on the log information; and updating the corresponding relation between the IP and the MAC recorded by the self based on the latest corresponding relation. The log related content records a MAC field, a MAC address, an IP field and an IP address. The MAC field is as follows: hardware Ethernet, the information behind this field is the MAC address. For example, the MAC address of a certain network access device can be recorded as: hardware southern 00:0c 29:51: b3: d 9.
In order to save computer resources of the DHCP server and not increase the pressure of the DHCP server, in this embodiment, a function is not added to the DHCP server, but only log-related contents that are originally recorded in the DHCP server are obtained, and then the server obtains the latest IP and MAC correspondence from the log-related contents to update information.
In a specific embodiment, the server may monitor a storage path in the DHCP server for storing the log-related content, so as to obtain the log-related content and ensure the obtaining accuracy. Meanwhile, the scheme does not need to request an ARP table to the switch and disassemble the message, and can improve the information updating accuracy rate on the premise of not increasing the pressure of the switch.
The following embodiments are described in detail with respect to the schemes provided in the present application in conjunction with specific scenarios. As shown in fig. 2, in a scenario of dynamic IP allocation, each network access device carries its own MAC address and applies for an IP address from a DHCP server through a DHCP protocol, so that the DHCP server can sense and record the MAC address of the network access device in the current network and the used IP address at the first time, and the DHCP server collects IP allocation information as its own work log, thereby obtaining the work log in the DHCP server to determine the correspondence between IP and MAC, and being capable of timely and accurately obtaining the MAC address of the network access device in a three-layer network environment.
For this reason, the embodiment deploys a log collection component in the DHCP server to obtain the working log in the DHCP server. Meanwhile, the DHCP server is in communication connection with the server side, so that the server side can timely obtain a working log of the DHCP server, and the server side can obtain information such as an MAC address, an IP and MAC corresponding relation and the like of the network access equipment from the log.
Referring to fig. 4, the process of the network access device applying for the IP address from the DHCP server includes: the network access equipment sends a DHCP request message to search a DHCP server existing in the current network environment, the DHCP server receives the DHCP request message and then puts an IP address available for use in a repackage and sends the repackage to the network access equipment, the network access equipment requests to use the IP address, and after receiving the request of the network access equipment requesting to use the IP address, the DHCP server replies an ack confirmation message to the network access equipment to indicate that the DHCP server agrees to the network access equipment to use the IP address. Then, the network access device can use the IP address to access the network, and the IP address allocated by the DHCP server to the network access device, the MAC address of the network access device, and other information are recorded in its working log by the DHCP server, so that once the log collection component in the DHCP server detects a log change, the working log of the DHCP server can be sent to other functional components in the server, and the server can obtain IP-MAC data from the logs. The server side can actively establish communication connection with the DHCP server and then wait for a log collection component in the DHCP server to send IP-MAC data, so that the acquisition of the MAC address of the network access equipment in a cross-three-layer environment is completed.
Wherein, the working log of the DHCP server is stored under the appointed path in the DHCP server. In this embodiment, taking the RHEL 5 system as an example, the log storage path is set as follows: the paths can store the following information: various timestamps of IP assignment, device MAC addresses (00:0c:29:51: b3: d9), device identifiers (\001\000\014) Q \263\331), device names (linux-5jlv), etc., which are embodied in the log as:

}
specifically, the log collection component may be configured individually, such as: configuring storage path, sending path, event management, regular matching, log filtering, rewriting, alarming and other functions.
The storage path is configured as follows:
Figure BDA0003662695990000061
the transmission path configuration is as follows:
Figure BDA0003662695990000062
therefore, the embodiment can acquire the equipment MAC address from the log recorded by the DHCP server, and can realize quick and accurate acquisition. The DHCP server is generally good in performance, performance pressure cannot exist, log collection is carried out on the DHCP server to obtain the MAC address, and obtaining timeliness and accuracy can be improved.
