Description
Technical Field

Background
Currently, there are many small and medium-sized enterprises using traditional switches of the Huashi, Huasan and Cisco brands, while large enterprises such as Google, Amazon and Facebook have started to take the lead to use white-brand switches. The former is programmable and the latter is not programmable, as compared to conventional switches. The biggest bright spot of the white-card switch is strong openness, that is, the operating system, software and other aspects of the white-card switch have more choices for users.
The switches are classified according to seven layers of ISO and can be divided into two-layer switches and three-layer switches, the two-layer switches belong to data link layer equipment, can identify MAC address information in a data packet, forward according to MAC addresses, and record the MAC addresses and corresponding ports in an internal address table. Three-layer switching (also called multi-layer switching technology, or IP switching technology) is proposed with respect to the traditional switching concept. As is well known, the conventional switching technique operates at the data link layer, which is the second layer in the OSI network standard model, and the three-layer switching technique achieves high-speed forwarding of data packets at the third layer in the network model. Briefly, the three-layer switching technique is: two-layer switching technology + three-layer forwarding technology.
Various problems exist today because the network operating systems (e.g., sonic, etc.) used by data center switches are themselves open source software and have a short development history. The current SONIC version has no IP address adding and deleting verification mechanism, so that different ports can be configured with the same IP address segment, the whole network data is not communicated, and meanwhile, the chaos of a switch database can be caused.

s600, prompting relevant command failure information in response to the fact that IP address data do not exist in the database file table in a query mode, and deleting the IP address data in response to the fact that the IP address data are queried in the database file table.
In some embodiments of the present invention, the method automatically queries the IP address status of the switch port to form a db (database file) table corresponding to the port and the IP address, and fig. 2 is a flowchart illustrating an IP address adding process according to an embodiment of the IP address adding and deleting verification method for the switch port according to the present invention, as shown in fig. 2, if the IP address exists in the port, the IP address is added to the db table, and the port does not exist but exists in the db table, and the corresponding entry in the table is directly deleted. When the switch port is used as a three-layer port for data forwarding, an IP address field needs to be configured for each port, and the IP address field needs to be paid attention to when adding the port and cannot be the same as the IP addresses of other ports, so that a port IP address adding and checking mechanism is designed. And during adding, inquiring the db table, checking whether the IP address exists, and if so, indicating an error if the adding is unsuccessful. In the using process, a networking mode can be changed according to the actual using condition of a current user, the IP address of a port is changed, the IP address needs to be deleted firstly in the changing process, an IP address error written when an operator operates the network operating system can occur in the deleting process, but the network operating system of the current data center white board switch does not have an IP address deletion checking method, so the error can not be reported, the completed port IP address deletion checking mechanism is designed through the whole logic analysis, and the function stability of the switch is ensured. Fig. 3 is a flowchart illustrating an IP address deletion process according to an embodiment of the method for checking addition and deletion of an IP address of a switch port of the present invention, as shown in fig. 3, when deleting, querying a db table, and determining whether a matching port and an IP address exist, if so, directly deleting the table entry in the table, and not directly reporting an error.
According to some embodiments of the method for verifying addition and deletion of an IP address of a switch port, in response to determining that data of an added IP address is not duplicated with data of an IP address already recorded in a database file table, adding an IP address to a port where no IP address exists and recording the data of the added IP address in the database file table further includes:
responding to the situation that the added IP address and the data of the recorded IP address in the database file table are not repeated, and verifying whether the added IP address meets the IP address classification standard or not;
and in response to the added IP address meeting the IP address classification standard, adding the IP address to the port without the IP address and recording the data of the IP address into a database file table.
In some embodiments of the present invention, it is verified whether the added IP address meets the IP address classification standard, and when the added IP address does not meet the IP address classification standard, information that the format of the IP address is incorrect is prompted, and the added IP address is not added to the port. The operator can check the IP address according to the prompt. If all the ports are inquired to have no IP address, the IP address can be directly added, whether the added IP address meets the IP address classification standard needs to be verified, and the added IP address can be added to the ports and recorded in the database file table only if the added IP address meets the classification standard.
According to some embodiments of the method for verifying the addition and deletion of the IP address of the switch port, the database file table includes port data and data of the IP address corresponding to the port, and the database file table is configured to perform a data update operation at preset time intervals.
In some embodiments of the present invention, the update operation cycles every 5 seconds, automatically updating the db table containing port data and IP address data corresponding to the ports.
According to some embodiments of the method for checking addition and deletion of an IP address of a switch port of the present invention, the method further comprises:
responding to the end of each data updating operation, and detecting whether an IP address exists in a port of the switch or not within preset time; and responding to the existence of the IP address, and recording the data of the IP address and the data of the port corresponding to the IP address into a database file table.
