DETAILED DESCRIPTION

[0021] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0022] The following describes the technical terms "switch", "port", "SSH", "TELNET", "MAC address table", "ARP" and "JSON" that appear in the present invention.

[0023] switch A switch is a network device that is mainly used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. Switches play a vital role in computer networks. Whether in enterprise networks, campus networks or home networks, switches are indispensable equipment for building a stable and efficient communication environment.

[0024] Port (also called interface) A switch port is an interface in a network device used to connect network devices and transmit data. These ports have different types and functions to meet various network needs. In a logical sense, ports can be divided into several types, including: Access port: belongs to only one VLAN and is used to connect terminal devices such as computers.

[0025] Trunk port: allows multiple VLANs to pass through, is used as the interface between switches, and supports the reception and transmission of multiple VLAN messages.

[0026] Hybrid port: allows multiple VLANs to pass through, is used as an interface for switches or computers, and supports the reception and transmission of multiple VLAN messages.

[0027] SSH SSH is the abbreviation of Secure Shell, which was developed by the Network Working Group of IETF. SSH is a security protocol based on the application layer. SSH is a more reliable protocol designed to provide security for remote login sessions and other network services.

[0028] TELNET TELNET is a remote login protocol, a network protocol based on TCP / IP protocol, used to establish remote connections between computers.

[0029] MAC address table The MAC address table of a switch, also known as a forwarding table, is an important data structure used by the switch to forward frames. It records the correspondence between MAC addresses and ports, as well as information such as the VLAN to which the port belongs.

[0030] ARP The ARP protocol, or Address Resolution Protocol, is a network layer protocol that runs on each network node and is responsible for completing the mapping of the host IP address to the MAC address. It maintains the ARP table and caches the mapping relationship between the host's IP address (network address) and MAC address (physical address).

[0031] JSON JSON (JavaScript Object Notation) is an open standard, lightweight file format and data exchange format that is easy to read and write. Its concise and clear hierarchical structure can effectively improve network transmission efficiency.

[0032] There are several problems in the existing network device information collection method: 1. The software system function needs to periodically collect switch information. Therefore, due to different switch manufacturers or types in different projects, it is necessary to add or modify codes one by one to adapt and implement the information collection process, which results in high personnel investment costs; 2. The more types of switches that are compatible with the software system, the more types of management there are, and the code will be too redundant and bloated, so the cost of code maintenance is high.

[0033] 3. The collection process matches different collection processing programs according to the manufacturer and type. If the switches of the same manufacturer and the same type have inconsistent versions, sometimes there will be differences in the information collection process. Currently, there is a strong correlation and poor compatibility.

[0034] In view of this, the purpose of the embodiments of the present invention is to provide a network device information collection method, a network device information collection device, an electronic device, a machine-readable storage medium and a computer program product, so as to solve the defects of the existing methods in network device information collection, such as long adaptation cycle, cumbersome operation, high labor cost and low operation and maintenance efficiency.

[0035] Method Embodiment Please refer to Figure 1 , an embodiment of the present invention provides a network device information collection method, comprising: Step 100: Obtain a device identification of a network device.

[0036] The electronic device obtains a device identification of a network device. The network device may be a router, a switch, etc. The network device in the embodiment of the present invention is described by taking a switch as an example. The device identification may be various identifications that uniquely characterize the switch. For example, the device identification may be an IP address of the switch, a device ID, etc. In the embodiment of the present invention, the device identification may be an IP address of the switch.

[0037] Step 200: Determine a target data rule template associated with the device identification based on a set mapping rule.

[0038] Wherein, the set mapping rule includes data rule templates associated with different device identifiers. For example, in the embodiment of the present invention, the technician can set up the interface in the electronic device in advance to determine the data rule templates corresponding to the IP addresses of different switches. For example, the IP address 0.0.0.1 of switch 1 corresponds to data rule template 1, and the IP address 0.0.0.2 of switch 2 corresponds to data rule template 2. The embodiment of the present invention determines the target data rule template associated with the device identifier based on the set mapping rule. The target data rule template includes a data acquisition rule for the network device corresponding to the device identifier. The device information of the network device acquired by the data acquisition rule includes at least one of the port table, MAC address table and ARP table of the switch. In one embodiment, the device information of the network device acquired by the data acquisition rule includes the port table, MAC address table and ARP table of the switch. The port table needs to collect the switch port name, port description, port VLAN, port type, port attributes, etc.; the MAC table needs to collect the switch port name, port VLAN, MAC address; the ARP table is generally general information, mainly IP address information and MAC address information.

[0039] In one embodiment, when the device information of the network device acquired by the data acquisition rule includes the port table, MAC address table and ARP table of the switch, the data rule template can be defined in JSON format, and the rule description is mainly based on three nodes: int_table (port information), mac_table (MAC address forwarding table), arp_table (ARP information). In one embodiment, the data rule template is as follows Figure 2 As shown. Figure 2 For the description of the port table node rules, see Table 1.

[0040] Table 1

[0041] Among them, Figure 2 For a description of the MAC address table node rules, see Table 2.

[0042] Table 2

[0043] Among them, Figure 2 For the description of the ARP table node rules, see Table 3.

[0044] Table 3

[0045] Step 300: Collect device information of the network device based on the target data rule template.

[0046] The electronic device collects the device information of the network device based on the target data rule template. In one embodiment, the specific processing process is to log in to the switch through the data collection service according to the pre-defined target data rule template, send commands to obtain information (port table, MAC table, ARP table) one by one, match the data rules according to the command execution results, and extract the values ​​of the corresponding nodes, thereby completing the entire information collection process. The data collection service is a parsing engine service based on the data rule template of the switch. Its main functions are to log in to the switch, issue commands and receive the returned result information, and to match and extract data based on the returned information, and to realize the information acquisition process according to the defined rules.

[0047] The embodiment of the present invention determines the target data rule template associated with the device identifier based on the set mapping rule, and then collects the device information of the network device based on the target data rule template. The embodiment of the present invention realizes the information collection of network devices (such as switches) based on the data rule template, which can quickly complete the adaptation of network devices and avoid the process of obtaining switch information collection by adding or modifying codes, thereby improving operation and maintenance efficiency and reducing labor costs. In addition, the data rule template of the embodiment of the present invention is independent of the switch manufacturer, type, and model, which greatly improves convenience and flexibility.

[0048] In other aspects of the embodiments of the present invention, step 300, collecting device information of the network device based on the target data rule template, includes: Step 310: parse the target data rule template and log in to the network device.

[0049] Step 320: Send an information acquisition command to the network device based on the target data rule template.

[0050] Step 330: Receive a command execution result of executing the information acquisition command sent by the network device.

[0051] Step 340: extract information from the command execution result based on the set data extraction command to obtain device information of the network device.

[0052] Please refer to Figure 3, the electronic device performs the step of parsing the target data rule template when acquiring the target data rule template. When the electronic device has a parsing error, the switch information acquisition is terminated; when the parsing is correct, the step of logging into the switch is performed. The data acquisition rule in the target data rule template includes the information acquisition command and the setting data extraction command. The electronic device sends the information acquisition command in the data acquisition rule to the switch, that is, the electronic device sends the information acquisition command to the switch, and the switch performs switch information acquisition based on the information acquisition command and returns the switch information to the electronic device. The switch information may include at least one of a port table, a MAC table, and an ARP table. In one embodiment, the switch information includes a port table, a MAC table, and an ARP table. The electronic device parses the switch information to obtain the port table, the MAC table, and the ARP table. The electronic device then extracts information from the command execution result based on the setting data extraction command to obtain the port table, the MAC table, and the ARP table of the switch. Subsequently, the port table, the MAC table, and the ARP table of the switch are written into a data storage device.

[0053] The data acquisition rules of the target data rule template in the embodiment of the present invention include the information acquisition command and the setting data extraction command. The target data rule template in the embodiment of the present invention can support multiple command configurations. For example Figure 2 The "cmds" of "int_table" includes multiple commands, the "cmds" of "mac_table" includes multiple commands, and the "cmds" of "arp_table" includes multiple commands. For example, the port information acquisition process usually requires multiple commands (usually 2) to obtain the complete information of a switch port, so the acquisition process will send command information in sequence according to the content defined by the current port rule, associate them through the port name, and summarize the execution results of multiple commands into a complete information and write it into the data storage.

[0054] In addition, the data acquisition rules of the embodiment of the present invention are constructed based on regular expressions. The data rule template of the embodiment of the present invention is suitable for obtaining the port table, MAC address table, and ARP table information of the switch, and the data rule template is defined in JSON format. Each rule in the data rule template can support regular expression parsing data, which is simple and clear, flexible in configuration, and supports extensibility. Other information can be obtained according to needs, as long as the implementation can support this custom field information parsing, so as to meet more functional needs of the software system.

[0055] In other aspects of the embodiment of the present invention, step 340, extracting information from the command execution result based on the setting data extraction command to obtain device information of the network device, includes: When the command execution result is in the form of a string, the command execution result is extracted based on a set regular expression to obtain the device information of the network device; when the command execution result is in the form of a data list with blank values, the command execution result is extracted based on the column header method to obtain the device information of the network device; and when the command execution result is in the form of a data list without blank values, the command execution result is extracted based on the column index method to obtain at least one of the device information of the network device.

[0056] The data extraction process of the embodiment of the present invention can support matching of character strings in a regular manner, and can also obtain the value of the column according to the display format of the data list, thereby realizing the entire information collection process.

[0057] For example, see Figure 4 , when the returned data is in the form of a string of data. The string data has an obvious start mark or end mark (such as the acquisition of switch port information, the start mark is interface and the end mark is !). For this data format, "cmd_type" can be configured as "by_str" (see Figure 2 The rule configuration of show running-config in the data rule template). That is, by setting a regular expression to extract the command execution result, the switch port information of the network device is obtained. For example, in one embodiment, the following regular expression can be used to realize the collection of switch port information: \b(?:GigabitEthernet|FastEthernet)([0-9]\ / [0-9]+)\b.

[0058] Among them, \b: indicates a word boundary, ensuring that we match the complete port name and not part of other text. (?:GigabitEthernet|FastEthernet): is a non-capturing group used to match GigabitEthernet or FastEthernet strings. ([0-9]\ / [0-9]+): is a capturing group used to match the port number. Here it is assumed that the port number consists of two numbers separated by a slash ( / ). The first number may be one or more digits, but the second number is at least one digit. \b: again indicates a word boundary.

[0059] For another example, please refer to Figure 5 , when the returned data is in the form of a data list with blank values, this method uses the column header field (such as Figure 5The header fields are Port, Name, Status, Vlan, Duplex, Speed, and Type. The start and end positions are calculated, and the actual data and the list headers are aligned to avoid data confusion caused by empty strings during the line-by-line reading process (such as Figure 5 The value corresponding to Name is an empty string). This data format can configure "cmd_type" to "by_list_title" (see Figure 2 The rule configuration of show int status in the data rule template). That is, the command execution result is extracted by column heading to obtain the port information of the switch.

[0060] For another example, see Figure 6 , when the returned data is in the form of a data list without blank values, this method corresponds to the case where the target value does not have a blank value. The target value can be directly extracted according to the column index method. This data format can configure "cmd_type" to "by_list_index" (see Figure 2 The rule configuration of show mac address-table in the data rule template). That is, the command execution result is extracted by column index to obtain the MAC address table information of the switch.

[0061] Therefore, the embodiment of the present invention can parse the value returned by the switch in paragraph string or list mode (by column title, by column index), which is highly flexible.

[0062] In summary, please refer to Figure 7In the embodiment of the present invention, the technician configures and sets mapping rules in the interface of the electronic device in advance, obtains data rule templates associated with different device identifiers and writes them into the data storage device for data storage. After the storage is successful, the target data rule template associated with the device identifier of the switch is determined from the data storage device based on the set mapping rules. When the target data rule template is obtained, the electronic device performs the step of parsing the target data rule template. When the electronic device has a parsing error, the switch information collection ends; when the parsing is correct, the step of logging into the switch is performed. The data acquisition rule in the target data rule template includes the information acquisition command and the set data extraction command. The electronic device sends the information acquisition command in the data acquisition rule to the switch, that is, the electronic device sends the information acquisition command to the switch, and the switch performs switch information acquisition based on the information acquisition command and returns the switch information to the electronic device. In one embodiment, the switch information includes a port table, a MAC table and an ARP table. The electronic device parses the switch information to obtain the port table, the MAC table and the ARP table. The electronic device then extracts information from the command execution result based on the set data extraction command to obtain the port table, the MAC table and the ARP table of the switch. Subsequently, the port table, the MAC table and the ARP table of the switch are written into the data storage device. Finally, the switch's port table, MAC table and ARP table are read from the data storage device for interface display.

[0063] The data rule templates of the embodiment of the present invention are described below through several example templates.

[0064] Template 1: { "int_table": { "cmds": [ { "cmd": "display current-configuration", "cmd_end": "]", "cmd_type": "by_str", "reg_port": "interface (.+)", "reg_vlan": "port access vlan (.+)", "reg_trunk": "port link-type (.+)|port (.+) permit vlan|port (.+)vlan", "reg_trunkflag": "trunk" }, { "cmd": "display interface brief", "cmd_end": "]", "cmd_type": "by_list_index", "reg_port": "1", "reg_up": "2", "reg_desc": "7" } }, "mac_table": { "cmds": { "cmd": "display mac-address", "cmd_end": "]", "cmd_type": "by_list_index", "reg_mac": "1", "reg_vlan": "2", "reg_port": "4" } }, "arp_table": { "cmds": { "cmd": "display arp", "cmd_end": "]", "cmd_type": "by_list_index", "reg_ip": "1", "reg_mac": "2" } } } Template 2: { "int_table": { "cmds": { "cmd": "show running-config", "cmd_end": "#", ​​​"cmd_type": "by_str", "reg_port": "interface (.+)", "reg_portvalid": "Fa.+ / |Gi.+ / ", "reg_desc": "description (.+)", "reg_vlan": "switchport access vlan (.+)", "reg_trunk": "switchport mode (.+)", "reg_trunkflag": "trunk", "reg_nextnode": "!|end" }, { "cmd": "show int status", "cmd_end": "#", "cmd_type": "by_list_title", "reg_port": "Port", "reg_portvalid": "Fa.+ / |Gi.+ / ", "reg_up": "Status", "reg_upflag": "connected" } ] }, "mac_table": { "cmds": [ { "cmd": "show mac address-table", "cmd_end": "#", "cmd_type": "by_list_index", "reg_mac": "2", "reg_vlan": "1", "reg_port": "4" } ] }, "arp_table": { "cmds": { "cmd": "show arp", "cmd_end": "#", "cmd_type": "by_list_index", "reg_ip": "2", "reg_mac": "4" } } } Template 3: { "int_table": { "cmds": { "cmd": "display current-configuration", "cmd_end": "]", "cmd_type": "by_str", "reg_port": "interface (.+)", "reg_vlan": "port access vlan (.+)", "reg_trunk": "port link-type (.+)|port (.+) permit vlan|port (.+)vlan", "reg_trunkflag": "trunk" }, { "cmd": "display interface brief", "cmd_end": "]", "cmd_type": "by_list_index", "reg_port": "1", "reg_up": "2", "reg_desc": "7" } }, "mac_table": { "cmds": { ​​"cmd": "display mac-address", "cmd_end": "]", "cmd_type": "by_list_index", "reg_mac": "1", "reg_vlan": "2", "reg_port": "4" } ] }, "arp_table": { "cmds": [ { "cmd": "display arp", "cmd_end": "]", "cmd_type": "by_list_index", "reg_ip": "1", "reg_mac": "2" } ] } } The embodiment of the present invention can realize switch information collection based on a universal data rule template. Under the same rule parsing engine, there is no need to add or modify code. It only needs to redefine the configuration data rule template in the electronic device interface and associate it with the switch through the device identifier (IP address, etc.), so as to quickly complete the adaptation collection of switch information. If there is a difference from the expected result, the result output can be reviewed by adjusting the data rule template. The operation is simple, convenient and flexible.

[0065] In other words, the main technical idea of ​​the embodiment of the present invention is to achieve the purpose of obtaining switch information by defining a data rule template based on switch information collection and implementing a matching parsing engine (i.e., data collection service) therewith, thereby reducing the adaptation cost and maintenance cost of R&D in the process of participation. The commands and return results corresponding to different switches for obtaining information may be different. The adaptation process can be quickly completed by referring to the data rule template for modification or minor adjustments. This idea or method can be extended to other information acquisition (except port table, MAC address table, ARP table), and can also be applied to other network devices (such as routers), so as to meet more functional requirements of the software system.
