It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.

In view of the above-mentioned objects, a first aspect of the embodiments of the present invention provides an embodiment of a method for configuring a virtual local area network of a white box switch. Fig. 1 is a schematic diagram illustrating an embodiment of a method for configuring a virtual local area network of a white box switch according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:

s1, inquiring the configured virtual local area network ID of the white box switch, and forming a VLAN (virtual local area network) ID table;

s2, responding to the command of receiving the configuration virtual local area network, creating a new virtual local area network ID, and judging whether the new virtual local area network ID exists in the VLANID table;

s3, responding to the VLAN ID table without the new virtual local area network ID, setting the IP address of the new virtual local area network ID, and judging whether the IP address and the existing IP address in the VLAN ID table belong to the same network segment; and

and S4, configuring the mask of the IP address in response to the fact that the IP address and the IP address already existing in the VLAN ID table do not belong to the same network segment.

The white box switch is a switch with thoroughly separated hardware and software, and when the hardware switch leaves a factory, except BootLoader (software), no software exists, and a customer can additionally purchase software or write software according to own requirements. The existing white box switch added and deleted VLANIP function is imperfect, and has no functions of VLAN ID verification, IP address verification and mask setting, so that error configuration can be issued, the whole network data is not passed, and simultaneously, the database of the switch can be disordered.

And inquiring the configured virtual local area network ID of the white box switch, and forming a VLAN ID table. The configured virtual local area network ID of the white box switch can be inquired in real time, or can be inquired at preset time intervals, and the white box switch can be inquired before a new virtual local area network ID is configured. The queried virtual local area network IDs can be arranged according to a certain sequence to form a VLAN ID table, so that the query of a user is facilitated.

And in response to receiving a command for configuring the virtual local area network, creating a new virtual local area network ID and judging whether the new virtual local area network ID exists in the VLAN ID table. The command to configure the virtual local area network typically includes a VLAN ID, an IP address, and a mask. When a command for configuring the virtual local area network is received, a new virtual local area network ID may be created, but the new virtual local area network ID may already exist in the VLAN ID table, so it is necessary to determine whether the new virtual local area network ID exists in the VLAN ID table, and if the new virtual local area network ID already exists in the VLAN ID table, it may be suggested that the new virtual local area network ID exists.

And responding to the situation that the new virtual local area network ID does not exist in the VLAN ID table, setting the IP address of the new virtual local area network ID, and judging whether the IP address and the IP address which already exists in the VLAN ID table belong to the same network segment. If the new vlan ID does not exist in the vlan ID table, the new vlan ID may be set, and an IP address of the new vlan ID may be set, and the IP address may be referred to as a first IP address in order to be distinguished from other IP addresses. When the first IP address is added, whether the IP address exists under the VLAN interface or not is judged firstly, if the IP address does not exist, the first IP address can be directly added, if the IP address exists, whether the first IP address and the existing IP address belong to the same network segment or not is verified, if the first IP address and the existing IP address do not belong to the same network segment, whether the first IP address is in compliance or not can be verified, and if the compliance rule is configurable, the configuration of the non-compliance rule fails.

And configuring a mask of the IP address in response to the fact that the IP address and the IP address which already exists in the VLAN ID table do not belong to the same network segment. When the IP address does not belong to the same network segment as the IP address already existing in the VLAN ID table, a mask of the IP address can be configured. In some embodiments, said configuring the mask of the IP address comprises: judging whether mask setting exists in the command or not; and in response to the mask setting being present in the command, determining whether the mask setting is a correct number of bits and performing the setting based on the determination. If the specific mask configuration does not exist in the command, the command is issued according to 32 bits, and if the specific mask configuration exists in the command, whether the mask configuration is in compliance is verified, for example, whether the mask configuration is a number within 1-32 can be verified, and if the mask configuration is exceeded, the configuration is failed.

In some embodiments, further comprising: in response to receiving a command to delete an IP address corresponding to an ID, the corresponding IP address is deleted from the vlan ID table. In some embodiments, said removing said corresponding IP address from the VLAN ID table comprises: judging whether the ID corresponding to the ID exists in the VLAN ID table or not; and in response to the presence of an ID corresponding to the ID in the VLAN ID table, determining whether the corresponding IP address is present and performing deletion based on the determination result. In some embodiments, the determining whether the corresponding IP address exists comprises: and judging whether the corresponding IP address has a mask or not.

Fig. 2 is a flowchart illustrating an embodiment of a method for configuring a virtual local area network of a white box switch according to the present invention. As shown in fig. 2, starting at block 101 and proceeding to block 102, the box switch is queried for the virtual local area network ID that it has configured and forms a VLAN ID table; continuing to block 103, in response to receiving a command to configure a virtual local area network, a new virtual local area network ID is created; proceeding to block 104, determining whether the new VLAN ID exists in the VLAN ID table, if yes, ending directly, if no, proceeding to block 105, and setting the IP address of the new VLAN ID; then, the process proceeds to block 106, where it is determined whether the IP address and the existing IP address in the VLAN ID table belong to the same network segment, and if yes, the process ends directly, otherwise, the process proceeds to block 107, where a mask of the IP address is configured, and then the process proceeds to block 108, where the process ends.

It should be particularly noted that, the steps in the embodiments of the method for configuring a whitebox switch vlan described above can be mutually intersected, replaced, added, and deleted, so that these methods for configuring a whitebox switch vlan are also intended to fall within the scope of the present invention, and should not limit the scope of the present invention to the embodiments.
