At present, a network manager needs to comprehensively analyze a drawn network topology structure according to an ARP table and an MAC table of a switch and an actual situation, so as to correspond a device type, a device IP, and a device MAC of a device and generate a connection relationship between the devices. In the prior art, a switch needs to be frequently and manually connected, an MAC table and an ARP table are obtained, and the IP and MAC of equipment, the equipment type of the equipment and the equipment type of the equipment are manually analyzed, and a topological structure is drawn.

Therefore, the network topology generation scheme is provided, the generation efficiency of the network topology can be improved, and the workload of network management personnel is reduced.
Referring to fig. 1, an embodiment of the present application discloses a method for generating a network topology, including:
step S11: an IP address field and SNMP (simple network management protocol) parameters are configured.

In a specific implementation manner, this embodiment may resolve the IP address field into a corresponding IP address; SNMP connection is carried out on the analyzed IP address; and acquiring the MAC address and the device type of the connected target device to obtain the device information. That is, in this embodiment, through the configured IP address field and SNMP parameter, the device matched in the network environment is discovered and the type, IP, and MAC address of the device are determined and obtained. Specifically, the IP address field is first analyzed into an IP set composed of individual IPs, and an SNMP object creation method of SNMP4j. SNMP connections are then made for each IP in the IP set. The devices are primarily classified into servers and switches according to three switch-specific OIDs (object identifiers) of 1.3.6.1.2.1.17.1.2.6.0, 1.3.6.1.1.2.1.17.2.7.0. Obtaining the value of ipIndex by using 1.3.6.1.2.1.2.2.1.6+ IP, obtaining the MAC address of the equipment by using 1.3.6.1.2.1.4.20.1.2+ ipIndex, and encapsulating the obtained MAC address, equipment type, IP address and SNMP connection parameter information together. Finally, a device object (the device object contains IP, MAC, device type, SNMP connection parameter) set is obtained.
In addition, in a specific implementation manner, this embodiment may correct the device type, and remove devices that do not need to participate in the topology generation from the target device.
It should be noted that with the development of the computer industry, a plurality of equipment manufacturers are in the process of being transported, and all the manufacturers are in the same place. This also leads to problems, such as the server hardware devices being of substantially the same type but acting differently because of different software installations, etc. For these problems, the present embodiment may correct the device type, and remove the device that does not need to participate in the generation of the topology structure from the target device, specifically, may implement a function of manually modifying the device type, and provide a screening function, that is, remove the device that does not want to participate in the generation of the topology relationship.
For example, referring to fig. 2, fig. 2 is a flowchart of a network topology generation method disclosed in the embodiment of the present application.
Step S13: acquiring first switch information corresponding to switch equipment in the target equipment; the first switch information comprises an MAC address set and a switch port corresponding to each MAC address in the MAC address set; the MAC address set includes MAC addresses of devices that can be connected with the corresponding switch device.

Step S14: and determining a seed IP from the IP address.
In a specific implementation manner, in this embodiment, an IP is selected from all device IPs participating in the generation of the topological relation, and the IP is used as an uplink direction of the network, so that the upper layer relation of the devices in the network environment is analyzed according to the port number of the switch device where the IP is located, so as to determine the connection relation between the devices.
Step S15: and determining the connection relation of the target equipment by using the target port number corresponding to the seed IP and the first switch information.
In a specific implementation manner, in this embodiment, the MAC address corresponding to the target port number is deleted in the first switch information; establishing a first topological data set; the first topology data set comprises the MAC address set corresponding to the first switch device; the first switch device is all switch devices except the device corresponding to the seed IP in the target device; traversing the first topology data set, and determining first direct connection equipment connected with the seed IP; the first direct connection equipment corresponds to a target MAC address set; the target MAC address set is the MAC address set with the maximum number of MAC addresses in the first topological data set; traversing the target MAC address set to obtain the equipment type corresponding to each MAC address in the target MAC address set; establishing a second topological data set; the second topology data set comprises the MAC address set corresponding to second switch equipment, and the second switch equipment is equipment of which the equipment type corresponding to the MAC address in the target MAC address set is the switch equipment; traversing the second topology data set, and determining second direct-connection equipment connected with the first direct-connection equipment; if the device types corresponding to the MAC addresses in the target MAC address set are not switch devices, judging that the devices corresponding to the MAC addresses in the target MAC address set are directly connected with the first direct connection device; and continuously iterating until the connection relation of all the target devices is determined.
It should be noted that, because of the characteristics of the switch MAC table, after deleting all MAC addresses of the port where the seed IP is located, the closer the device MAC table connected to the seed IP, i.e., the MAC addresses in the corresponding MAC address set, the more distant the device MAC table, the fewer MAC addresses in the MAC table. For example, as shown in fig. 3, fig. 3 is a schematic diagram of a specific network topology disclosed in an embodiment of the present application, where a seed IP is located on port 1 of a switch C, a MAC of port 1 is removed, a MAC table of a device C includes a, B, and D, the seed IP is located on port 1 of the device a while port 1 includes a MAC of the device C, a MAC address of port 1 of the device a is deleted, a MAC table of the device a includes B and D, and so on, the farther a switch device from the seed node E, the fewer MAC addresses included in the MAC table of the switch device are. From which the network topology is derived.
Step S16: and binding the connection relation and the equipment information to generate a corresponding network topology structure.
That is, in the embodiment of the present application, a simple network protocol of SNMP may be used to search for a device within a specified IP range, and the device type, the MAC address, and the IP address are obtained for the matched device through the OID in the MIB, and the MAC table of the found switch device is obtained. And taking an appointed seed IP (IP which can be reached arbitrarily in a network environment) as an uplink direction in the network, deeply traversing the MAC table acquired by the SNMP by using a tree traversal idea, thereby integrating the connection relation among the MAC addresses, and finally binding the connection relation among the MAC addresses with the IP addresses and the equipment types to acquire the network topology structure.
Therefore, the embodiment of the application firstly configures an IP address field and SNMP parameters; acquiring equipment information of target equipment in the current network by using the IP address field and the SNMP parameter; the device information comprises a device type, an IP address and an MAC address; acquiring first switch information corresponding to switch equipment in the target equipment; the first switch information comprises an MAC address set and a switch port corresponding to each MAC address in the MAC address set; the MAC address set includes MAC addresses of devices connectable with the corresponding switch device; determining a seed IP from the IP address; determining the connection relation of the target equipment by using the target port number corresponding to the seed IP and the first switch information; and binding the connection relation and the equipment information to generate a corresponding network topology structure. Therefore, the IP address field and the SNMP parameters are configured firstly, then the equipment information of the target equipment and the first switch information are obtained, finally the connection relation of the target equipment is determined through the first switch information and the target port number of the seed IP, a corresponding network topology structure is generated, the generation efficiency of the network topology structure can be improved, and the workload of network managers is reduced.
Referring to fig. 4, an embodiment of the present application discloses a method for generating a network topology, including:
step S21: and configuring an IP address field and SNMP parameters.
Step S22: acquiring equipment information of target equipment in the current network by using the IP address field and the SNMP parameter; the device information includes a device type, an IP address, and a MAC address.
Step S23: acquiring first switch information corresponding to switch equipment in the target equipment; the first switch information comprises an MAC address set and a switch port corresponding to each MAC address in the MAC address set; the MAC address set includes MAC addresses of devices that can be connected with the corresponding switch device.
In a specific embodiment, SNMP may be used to send a request to the switch via the oid1.3.6.1.2.1.17.7.1.2.2.1.2, and the returned value is processed as follows: and removing the character string 1.3.6.1.2.1.17.7.1.2.2.1.2 from the key, then converting the hexadecimal system to obtain the MAC address, wherein the value is the port number of the MAC address, and generating a Map set macaddresportTable with the MAC address as the key and the port number as the value.
Step S24: acquiring second switch information of switch equipment in the target equipment; the second switch information includes switch ports and corresponding port types.
In a specific embodiment, SNMP is used to send a request to the switch over the oid1.3.6.1.2.1.2.2.1.3, and the returned value is processed as follows: and removing the character string 1.3.6.1.2.1.2.2.2.1.3 from the key, then obtaining the port number, taking the value as the port type of the port, and generating a Map set switchPortTypeTable with the port number as the key and the port type as the value.
Step S25: and eliminating the VLAN port in the first switch information and the MAC address corresponding to the VLAN port by using the second switch information.
This embodiment may combine switchportTypeTable and macaddrespsPortTable to remove a port (VLAN port) with a port type value of 136 from the macaddrespsPortTable.
It can be understood that, filtering the VLAN ports can avoid the situation that the same network device generates multiple nodes, thereby greatly improving the reliability of the network topology.
Step S26: and determining a seed IP from the IP address.
This embodiment finds the port number where the seed IP is located from the macaddresporttable table, and deletes all MAC addresses belonging to the port from the macaddresporttable.
Step S27: and determining the connection relation of the target equipment by using the target port number corresponding to the seed IP and the first switch information.
In a specific implementation manner, the switch device IP may be used as a key, and all MAC addresses in the macaddresporttable are extracted to form a Set < String > as a value, and the Set < String > is placed in the topology Set topoxymap. For example, referring to fig. 5, fig. 5 is a flowchart for preparing specific switch topology data disclosed in an embodiment of the present application. Generating a topological relation by using a topological set topotaxyMap, wherein the topological relation comprises the following steps: step one, traversing all switch MAC address macSet sets in the topotaxyMap, finding out the macSet set with the largest size, and determining the macSet as a parentmatset. And in the second step, the device corresponding to the parenTMacSet is a direct-connection device of the seed IP. Traversing the parentmast, judging the device type of each device corresponding to each MAC, if the device type is a switch, acquiring macSet of the device from topotaxyMap, and putting the macSet into a new nextMap set, wherein the device IP is key, and the macSet is value. And thirdly, deleting the equipment data in the nextMap from the topoxyMap, and performing the operations of the first step and the second step on the nextMap, and continuously iterating. When a macSet does not contain a switch device and the MAC of the macSet is not in the hasnoductutermac, the MAC in the switch is considered that the server MAC is directly connected with the switch, and the MAC is stored in the set hasnoductutermac set.
Taking the topology of fig. 3 as an example, the macSet of C is found to be the largest in the first operation, and it is determined that C is directly connected to E. The macSet set of C comprises MAC addresses of the devices A, B and D, the devices A and B are found to be switch devices after traversal, the macSet of the devices A and B is deleted from the topotaxyMap, a new nextMap is formed, and iteration is carried out. And (3) determining that A is directly connected with C because the size of the macSet of A in the nextMap is maximum, so that the macSet of A is obtained and traversed, B contained in the macSet is found to be a switch, the macSet of B is deleted from the nextMap to form a new set, the connection between B and A is determined, and iteration is executed again. And B does not contain the switch MAC, D in the MAC table is judged to be directly connected with the switch MAC, and the iteration of B is finished. And if the iteration returned to A finds that the macSet of A does not have the MAC address meeting the condition of the direct connection server, the iteration of A is finished, and the iteration returned to C has the same C as A. The topology iteration is completed. Thus, the analysis of the connection relationship of the devices in the entire network environment is completed.
Step S28: and binding the connection relation and the equipment information to generate a corresponding network topology structure.
That is, according to the embodiment of the present application, the IP address range and the SNMP parameter are configured, and the IP and MAC addresses of the individual devices can be obtained through the SNMP without obtaining the device information from the switch MAC table and the ARP table, so that the topology structure of the network is obtained, and manpower, material resources, and time consumed by network maintenance are greatly reduced.
