In order to facilitate understanding and explanation of the technical solution provided by the embodiments of the present application, the background technology related to the embodiments of the present application is first described.
Network devices such as firewalls, switches, and intrusion detection systems typically require a large number of network adapter interfaces (abbreviated network interfaces) to meet the many-sided demands of the network devices in terms of performance and functionality. When more network interfaces are used in the same network device, renaming is required for each network interface used to distinguish between different network interfaces.
At present, each network interface of the same network device is renamed in a manual mode, and the mode has the problems of low efficiency and high randomness, so that the subsequent use of the network interface is inconvenient. In addition, the manner of manual renaming may also cause a conflict between the naming of the network interface and the naming of other types of interfaces of the network device, or may cause a situation in which the naming of the network interface is inconsistent with the interface order of the actual physical interfaces of the network adapter.
Based on this, the embodiment of the application provides a method, a device and equipment for renaming a network adapter interface, which firstly acquire slot information of a network adapter card slot of a network device and interface sequences of at least two network interfaces corresponding to the slot information.

And then, acquiring interface identification information of at least two network interfaces, and changing original names corresponding to the interface identification information of the target network interfaces into standard names of the target network interfaces, wherein the target network interfaces are respectively used for each network interface. In this way, the embodiment of the application provides a more standard renaming mode of the network interface, namely, the new standard naming of each network interface corresponding to the slot position information is determined according to the slot position information of the network adapter card slot and the interface sequence of at least two network interfaces corresponding to the slot position information, thereby improving the renaming efficiency of the network interface and being convenient for the use of the network interface.
In addition, in the embodiment of the application, the interface renaming is performed according to the slot position information and the interface sequence of at least two network interfaces corresponding to the slot position information, so that the new standard naming of each network interface is related to the card slot corresponding to the network interface. The card slots corresponding to the network adapter interfaces are different from the card slots corresponding to other interfaces of the network equipment, so that the situation that conflicts exist between the naming of the network adapter interfaces and the naming of other interfaces of the network equipment can be reduced. When the embodiment of the application renames the interfaces, the interface sequence of the network interfaces is considered, so that the condition that the naming of the network adapter interfaces is inconsistent with the interface sequence of the actual physical interfaces of the network adapter can be reduced.

Those skilled in the art will appreciate that the frame diagram shown in fig. 1 is but one example in which embodiments of the present application may be implemented. The scope of applicability of the embodiments of the application is not limited in any way by the framework.
In order to facilitate understanding of the present application, a method for renaming a network adapter interface according to an embodiment of the present application is described below with reference to the accompanying drawings.
Referring to fig. 2, the flowchart of a method for renaming a network adapter interface according to an embodiment of the present application is shown in fig. 2, where the method may include S201-S205:
S201: and obtaining slot position information of a network adapter card slot of the network equipment.
Network devices and components are physical entities connected to a network, and there are many kinds of network devices, such as firewalls, switches, intrusion detection systems, and the like. The network adapter, i.e., a network card, generally includes an on-board network adapter (on-board card) and an extension network adapter (extension card) according to the installation manner of the network card on the network device. The board-mounted card is a network card embedded in the network equipment, and the expansion card is a pluggable network card. For firewalls, switches, and intrusion detection systems, network interfaces are in great demand, so a combination of on-board and expansion cards is often used. Typically, a network adapter is provided with a plurality of metal contact pads on one side and a network interface on the other side.
The network equipment is provided with a network adapter clamping groove, and the network adapter is inserted into the network adapter clamping groove, so that the network equipment is connected with the network equipment through the metal contact piece on the network adapter. The network interface on the network adapter is used to connect to a network, such as a LAN network. Thus, the network card acts as a connection intermediary to enable the network device to communicate with an external network. The on-board network adapter is fixedly connected with a network adapter clamping groove in the network equipment, and the expansion network adapter can be inserted into the network adapter clamping groove or pulled out from the network adapter clamping groove.
Alternatively, a peripheral component interconnect standard (PERIPHERAL COMPONENT INTERCONNECT, PCI) bus may be used as a local bus for network devices, primarily for the purpose of connecting external devices. The PCI bus has an independent address space, i.e., a PCI bus address space (PCI address or bus address for short). The network device may assign an independent PCI address to each network adapter card slot.
As an alternative example, the slot information of the network adapter card slot is the PCI address of the network adapter card slot. When a certain network adapter card slot is connected with a network adapter, the slot position information of the network adapter card slot can be acquired, and when the certain network adapter card slot is not connected with the network adapter, the slot position information of the network adapter card slot cannot be acquired. That is, in the embodiment of the present application, the slot information of each network adapter card slot of the network device is obtained, and the obtained slot information is the slot information of the network adapter card slot connected with the network adapter. There may be multiple network adapter card slots of one network device, and the acquired slot position information of the network adapter card slots may also be multiple.
In the embodiment of the application, the slot information of the network adapter card slot can be represented by slot_index, the slot represents the slot, the index represents the sequence number, and the whole slot_index represents the slot information. The slot position information of the network adapter card slot can also obtain the slot position number of the network adapter card slot, for example, the slot position number of the on-board card slot is represented by 0, and the slot position number of the expansion card slot is represented by other numbers. The corresponding relation between the slot information and the slot number of each type of network equipment is pre-bound, for example, PCI address 1 and PCI address 2 are bound with slot number 0, PCI address 3 is bound with slot number 1, PCI address 4 is bound with slot number 2, namely, PCI address 1 and PCI address 2 correspond to the card slot of the board, PCI address 3 corresponds to expansion card slot 1, and PCI address 4 corresponds to expansion card slot 2.
In one possible implementation manner, the embodiment of the present application provides a specific implementation manner for obtaining slot information of a network adapter card slot of a network device in S201, specifically please see A1-A3 below.
S202: and acquiring the interface sequence of at least two network interfaces corresponding to the slot position information.
The number of network interfaces corresponding to the slot information is usually a plurality of, and can be determined according to actual situations. For example, the number of network interfaces in an expansion network adapter (expansion card) is typically 2,4, or 8, i.e., a 2-port expansion card, a 4-port expansion card, or an 8-port expansion card. The number of network interfaces in an on-board network adapter (on-board card) is also typically 2,4, 6, 8 or 10. In practical applications, the number of network interfaces of the network adapter is generally even. In addition, the number of the network adapter card slots can be 1,2, 4 or 8.
In order to rename at least two network interfaces corresponding to the slot information, an interface sequence of at least two network interfaces corresponding to the slot information needs to be obtained.
According to the wiring standard, each network interface in the network adapter has a corresponding interface serial number. Each network interface has a corresponding interface serial number, and because the number of the network interfaces is a plurality of, the number of the interfaces is a plurality of. The plurality of interface serial numbers may form an interface sequence of the plurality of network interfaces corresponding to the slot information. The interface sequence of the plurality of network interfaces corresponding to the slot information is used to represent the sequence of the plurality of network interfaces, and the interface sequence number corresponding to each network interface is used to represent the ranking of the network interface in the plurality of network interfaces. The interface order of the plurality of network interfaces may be exemplarily understood as a network interface linear relationship.
In the embodiment of the application, the interface serial number of a network interface in the interface sequence can be represented by port_index, the port represents the interface, the index represents the serial number, and the port_index integrally represents the interface serial number in the interface sequence. For example, when the interface number of one network interface is 1, the network interface may be denoted as network interface 1.
And obtaining the interface sequence of at least two network interfaces corresponding to the slot information, wherein the corresponding relation between the interface sequence of the network adapter corresponding to the slot information in the network equipment and the interface sequence of the actual physical interface is required to be referred to.
The interface sequence of the network adapter corresponding to the slot information in the network device may be understood as the arrangement sequence of the network interfaces of the network adapter corresponding to the slot information in the operating system of the network device. For example, the network adapter A has 4 network interfaces, which are arranged in the operating system of the network device in the order of 1-2-3-4.
The interface order of the actual physical interfaces is the order of arrangement of the individual network interfaces of the network adapter on the physical host of the network device. For example, the 4 network interfaces of network adapter A are arranged in the order of 2-1-4-3 on the physical host. I.e. the network interface ordered 1 in the operating system of the network device is the 2 nd network interface on the physical host, and the network interface ordered 2 in the operating system of the network device is the 1 st network interface on the physical host.
At this time, the interface sequence of at least two network interfaces corresponding to the slot information may be determined according to the interface sequence of the actual physical interface.
In one possible implementation manner, the embodiment of the present application provides a specific implementation manner of the interface sequence of the network interface corresponding to the slot position information, and specific please refer to B1-B2 below.
S203: and determining the standard naming corresponding to each network interface in at least two network interfaces according to the slot position information and the interface sequence.
After the slot information and the interface order of at least two network interfaces corresponding to the slot information are obtained, standard naming of the network interfaces may be determined. In the implementation, the slot number can be determined according to the slot information, and the interface serial number of each network interface can be determined according to the interface sequence of at least two network interfaces corresponding to the slot information. Further, the standard naming of the network interface is determined by the slot number and the interface serial number corresponding to the network interface.
In practical applications, the corresponding interface naming may be determined according to the type of the network adapter. Based on this, as an optional example, when the network adapter is an on-board adapter, the interface naming of the network interface in the on-board adapter is determined according to the interface serial number corresponding to the network interface in the on-board adapter. For example, ethx is used, where "x" is the interface number, such as eth0, eth1, eth2, etc.
As another alternative example, when the network adapter is an extended network adapter, the interface naming of the network interface is determined by the slot number and the interface serial number corresponding to the network interface. For example, using the nomenclature of eth-szpx, where "s" represents the slot number designation, "z" is the specific slot number, "p" is the interface number designation, "x" is the specific interface number, such as eth-s1p1, eth-s1p2, eth-s1p3, and eth-s1p4. Taking eth-s1p1 as an example, this represents the network interface 1 in the expansion card slot 1.
It can be known that, because the card slot corresponding to the network adapter interface is different from the card slots corresponding to other interfaces of the network device, the standard naming of the network interface in the embodiment of the application can be bound with the slot number of the card slot corresponding to the network adapter. In this way, the situation that there is a conflict between the naming of the network adapter interface and the naming of the other interfaces of the network device can be reduced. Further, since the interface order of the network interfaces is considered when the interface renaming is performed, it is possible to reduce the case where the naming of the network adapter interfaces does not coincide with the interface order of the actual physical interfaces of the network adapter.
Meanwhile, based on the above, when a new expansion network adapter is connected with the network device, only the network card type of the new expansion network adapter, the slot position information of the network adapter slot corresponding to the new expansion network adapter, and the interface sequence of the network interfaces in the new expansion network adapter need to be determined, so that the new naming of each network interface in the new expansion network adapter can be determined, and the renaming of the network interfaces can be realized. Thus, when a new extended network adapter is connected to the network device, the expandability of the renaming of the network interface can be improved.
S204: interface identification information of at least two network interfaces is obtained.
Each network interface in the network adapter connected to the network adapter card slot corresponds to its own interface identification information.
As an alternative example, the interface identification information is a PCI address of network interfaces, each of which is bound with a pre-assigned PCI address. In an embodiment of the application, the interface identification information of the network interface may be represented by [ < bus > ] [ < slot > ] [ < func > ]. bus, slot, func is a PCI address identifier, where bus represents a bus number, slot represents a device number, and func represents a function block order. The interface identification information through the network interface can uniquely identify a physical network interface. For example, interface identification information of 4 network interfaces in a network adapter connected to a network adapter card slot is 02:00.0, 02:00.1, 02:00.2, and 02:00.3, respectively. In one possible implementation manner, the embodiment of the present application provides a specific implementation manner of acquiring interface identification information of a network interface corresponding to slot position information, which is specifically described below.
S205: and changing the original name corresponding to the interface identification information of the target network interface into the standard name of the target network interface. Wherein the target network interface is each of the at least two network interfaces.
After the standard naming of the target network interface is obtained, changing the original naming corresponding to the interface identification information of the target network interface into the standard naming of the target network interface. And the standard name corresponding to the interface identification information of the target network interface is the new name of the target network interface.
The contents of S201-S202, S204 can be understood that the slot information of the network adapter slot, the interface identification information of at least two network interfaces corresponding to the slot information and the interface sequence are obtained, and then [ < slot_index > ] [ < port_index > ] [ < bus > ] [ < slot > ] [ < func > ]. The [ < slot > ] [ < port_index > ] [ < bus > ] [ < slot > ] [ < func > ] may be described as a network interface relationship five-tuple.
It can be known that after the [ < slot_index > ] < port_index > ] in the network interface relation five-tuple is determined, each network interface corresponding to the slot information can be uniquely determined. Interface identification information [ < bus > ] [ < slot > ] [ < func > ] of each network interface corresponding to the same slot information can also be determined.
For example, determining the slot information to be 00:01.0 is an extended network adapter card slot 1, the corresponding extended network adapter has 4 network interfaces, and the acquired 4 interfaces of the network interfaces are in the order of 2-1-4-3. The standard designations for these 4 interface sequences are eth-s1p2, eth-s1p1, eth-s1p4, and eth-s1p3.
Then, it can be determined that the interface identification information corresponding to the 4 network interfaces is 02:00.0, 02:00.1, 02:00.2 and 02:00.3, respectively, and then the network interface corresponding to 02:00.0 is named as eth-s1p2, the network interface corresponding to 02:00.1 is named as eth-s1p1, the network interface corresponding to 02:00.2 is named as eth-s1p4, and the network interface corresponding to 02:00.3 is named as eth-s1p3.
In some possible implementations, the embodiments of the present application provide two specific implementations of changing the original naming corresponding to the interface identification information of the target network interface to the standard naming of the target network interface, specifically please see below.
Based on the above-mentioned content of S201-S205, the embodiment of the present application provides a method for renaming a network adapter interface, which includes obtaining slot information of a network adapter card slot of a network device and an interface sequence of at least two network interfaces corresponding to the slot information. Further, a standard naming of each of the at least two network interfaces is determined based on the slot information and the interface order. And then, acquiring interface identification information of at least two network interfaces, and changing original names corresponding to the interface identification information of the target network interfaces into standard names of the target network interfaces, wherein the target network interfaces are respectively used for each network interface. In this way, the embodiment of the application provides a more standard renaming mode of the network interface, namely, the new standard naming of each network interface corresponding to the slot position information is determined according to the slot position information of the network adapter card slot and the interface sequence of at least two network interfaces corresponding to the slot position information, thereby improving the renaming efficiency of the network interface and being convenient for the use of the network interface.
In a possible implementation manner, the embodiment of the present application provides a specific implementation manner for obtaining slot information of a network adapter card slot of a network device in S201, including:
a1: and acquiring the device identification corresponding to each bus address of the network device.
The network device may connect to some other device, assign a bus address to each device, and record the device identification of each device. The device identification of each of the network devices corresponds to the bus address of the device. A device identification may correspond to one or more bus addresses.
In this step, the device identifier corresponding to each bus address of the network device is acquired first. In the embodiment of the application, the bus address is a PCI address.
It will be appreciated that when the device identifier is available, it indicates that the device to which the device identifier belongs is connected in the network device.
A2: and identifying the equipment identifier of the network adapter from the equipment identifiers, and acquiring the bus address corresponding to the equipment identifier of the network adapter.
The network adapter is one of the devices to which the network device is connected. After the device identifiers corresponding to the bus addresses are acquired, the device identifier of the network adapter is identified from the device identifiers. Further, a bus address corresponding to the device identifier of the network adapter is acquired. For example, the device identifier that identifies the network adapter is 8088, and the bus address corresponding to the device identifier 8088 is acquired.
In practical application, as an alternative example, the PCI bus structure may be obtained through lspci-tv commands in the network device, and the bus address corresponding to the device identifier of the network adapter may be obtained. The expression form of the command is usually the form of command name+space+parameter, that is lspci is command name, -tv is parameter, and the command name and parameter are separated by space.
A3: and determining the bus address corresponding to the equipment identifier of the network adapter as slot position information of a network adapter card slot of the network equipment.
After the bus address corresponding to the device identifier of the network adapter is obtained, the bus address corresponding to the device identifier of the network adapter is determined to be the slot information of the network adapter slot of the network device, namely slot_index information in the network interface relation five-tuple. This facilitates the subsequent correspondence of the interface identification information of each network interface with the slot information of the card slot to which the network interface corresponds.
Based on the content of A1-A3, a specific implementation manner of determining slot information of a network adapter card slot of a network device is provided, namely, firstly, acquiring a device identifier of the network adapter, further acquiring a bus address corresponding to the device identifier of the network adapter, and determining the bus address as the slot information of the network adapter card slot of the network device.
Based on A1-A3, in a possible implementation manner, a type identifier corresponding to the device identifier of the network adapter may also be obtained, and it is determined that the network adapter belongs to an on-board network adapter or an extended network adapter according to the type identifier.
The network adapter comprises an on-board network adapter and an extension network adapter, and the on-board network adapter and the extension network adapter respectively correspond to respective type identifiers. For example, the type identifier corresponding to the on-board network adapter is 0101 or 0104, and the type identifier corresponding to the extension network adapter is 0103. After determining the type of the network adapter, the determination of the slot number of the network adapter card slot in the above embodiment can be facilitated.
Based on this, it may be determined that the network adapter belongs to an on-board network adapter or an extended network adapter according to the type identification. For example, when the type identifier 0104 is acquired, it is known that the network adapter belongs to the on-board network adapter.
In addition, the bus address corresponding to the device identifier of the network adapter can be determined to belong to the bus address of the on-board network adapter or the bus address of the extended network adapter according to the device identifier of the network adapter. For example, when the bus address corresponding to the type identifier 0104 is 00:05.0, it may be determined that the bus address is the bus address of the on-board network adapter; when the bus address corresponding to the type identifier 0101 is 00:03.0, determining that the bus address is the bus address of the on-board network adapter; when the bus address corresponding to the type identifier 0103 is 00:01.0, the bus address can be determined to be the bus address of the extended network adapter.

And acquiring an interface linear relation mapping function of the network adapter corresponding to the slot position information in advance. In an embodiment of the present application, the mapping function is written asWherein, x= { X 1,x2,x3......xn } is an interface sequence of the network adapter corresponding to the slot information in the network device, X i is each interface sequence number in the interface sequence, i=1, 2,3. Y= { Y 1,y2,y3......yn } is the interface order of the actual physical interface, and Y i is each interface sequence number in the interface order.

It can be appreciated that the interface linear relation mapping function provided aboveSo that the functionThis is true. Therefore, after knowing the interface sequence of the network adapter corresponding to the slot position information in the network equipment, the interface sequence of the actual physical interface of the network adapter can be determined through the interface linear relation mapping function. Further, the interface order of the actual physical interfaces of the network adapter is used as the interface order of the network interfaces corresponding to the slot information.
For example, an 8-port expansion card of model IG8011A, which corresponds to a first linear relationship sequence in an interface linear relationship mapping functionSecond linear relationship sequence/>When the interface sequence X＝{x1＝1,x2＝2,x3＝3,x4＝4,x5＝5,x6＝6,x7＝7,x8＝8} of the network adapter corresponding to the slot information in the network device, according to the provided first linear relation sequence and second linear relation sequence, the interface sequence of the actual physical interfaces of the network adapter can be Y＝{y1＝2,y2＝1,y3＝4,y4＝3,y5＝6,y6＝5,y7＝8,y8＝7}., that is, the first interface displayed in the network device is actually the second interface in the actual physical interfaces, the second interface displayed in the network device is actually the first interface in the actual physical interfaces, the third interface displayed in the network device is actually the fourth interface in the actual physical interfaces, and so on.
Based on the above content of B1-B2, it can be known that when the interface sequence of the network adapter corresponding to the slot information in the network device is different from the interface sequence of the actual physical interfaces, the interface sequence of the actual physical interfaces is obtained according to the interface linear relation mapping function, and the interface sequence of the actual physical interfaces is used as the interface sequence of at least two network interfaces corresponding to the slot information.

After the bus address corresponding to the device identifier of the network adapter is obtained and the bus address corresponding to the device identifier of the network adapter is determined to be the slot information of the network adapter slot of the network device, the file directory corresponding to the slot information can be determined through the obtained slot information of the network adapter slot. The file catalogue corresponding to the slot position information comprises interface identification information of the network interface corresponding to the slot position information. Therefore, the interface identification information of the network interface corresponding to the slot information can be directly obtained from the file catalog corresponding to the slot information.
For example, when the slot information of the network adapter card slot is determined to be 00:01.0, finding 00:01.0 under the/sys/bus/pc/devices/catalogue, and entering a folder corresponding to 00:01.0, wherein the file catalogue is listed in the folder. Interface identification information of each network interface corresponding to 00:01.0 is obtained from the file catalog, for example, 4 network interfaces, and the interface identification information is 02:00.0, 02:00.1, 02:00.2 and 02:00.3 respectively.
As an alternative example, the interface identification information of each network interface corresponding to the slot information may be obtained by commanding find/sys/bus/pcb/devices/slot information/-NAME DRIVER. That is, [ < bus > ] [ < slot > ] [ < func > ] of each network interface corresponding to the slot information is determined.

Wherein ls is the command name,/sys/bus/pcb/devices/0000: $ { bus }: $ { slot }, $ { func }/net is the address space, belongs to one of the parameters, and is spaced from the address space by spaces.
For example, if eth5 is obtained through ls/sys/bus/pcb/devices/0000:02:00.1/net, the original name of the network interface corresponding to the interface information identifier 02:00.1 of the network interface is named eth5, and the original name can be changed, for example, to be changed to eth-s1p1 through a command.
In addition, the Linux system issues a command to the operating system kernel in a system call mode, and after the operating system kernel receives the command, each PCI address in the network device is obtained, and whether the device corresponding to the PCI address is a network adapter or not is judged, and whether the conditions of the PCI address, the device corresponding to the PCI address does not exist, and the like are judged. When the device corresponding to the PCI address is not the network adapter and the PCI address exists but the device corresponding to the PCI address does not exist, the error is determined to occur. At this time, an error message is returned. And if no error occurs, acquiring the original name corresponding to the interface identification information of the target network interface.
C2: and closing the target network interface.
And after the original naming corresponding to the interface identification information of the target network interface is obtained, closing the target network interface to rename the target network interface.
As an alternative example, when the network device uses the Linux operating system, the ifconfig $old_name down command may be used to close the network interface. The old_name is the original name corresponding to the interface identification information of the target network interface.
And C3: and responding to a renaming request, namely changing the original name corresponding to the interface identification information of the target network interface into the standard name of the target network interface, wherein the renaming request comprises the original name corresponding to the interface identification information of the target network interface and the standard name of the target network interface.
After the target network interface is closed, the target network interface may be renamed. And triggering a renaming request by a user through a command, and responding to the renaming request, and changing the original naming corresponding to the interface identification information of the target network interface into the standard naming of the target network interface.
As an alternative example, when the network device uses the Linux operating system, the name of the network interface may be modified using the IP LINK SET $old_name name$new_name command. The $ new_name is the standard name of the target network interface.
And C4: and opening the target network interface.
After renaming the target network interface, opening the target network interface to complete renaming of the target network interface.
As an alternative example, when the network device uses the Linux operating system, the ifconfig $new_name up command may be used to enable the network interface.
It can be understood that when the Linux operating system is used by the network device, the original naming of the target network interface needs to be obtained first, and then the original naming of the target network interface is changed based on the original naming of the target network interface.

When the network device uses Dpdk user mode, the user can trigger renaming request through inter-process communication, and respond to the request to directly change the original naming corresponding to the interface identification information of the target network interface into the standard naming of the target network interface.
The Dpdk user state issues a command to the Dpdk program in an inter-process communication mode, and after the Dpdk program receives the command, each PCI address in the network device is acquired first, and whether the device corresponding to the PCI address is a network adapter or not is judged, and whether the situation that the PCI address exists but the device corresponding to the PCI address does not exist or not is judged. When the device corresponding to the PCI address is not the network adapter and the PCI address exists but the device corresponding to the PCI address does not exist, the error is determined to occur. At this time, an error message is returned. When no error occurs, the driver/dev/pegasus may be opened through the Open interface in Dpdk programs and a rename request may be issued through ioctl to rename the target network interface.
It can be understood that when the network device uses Dpdk user mode, the original name of the target network interface is not required to be obtained, and the corresponding original name of the target network interface can be directly changed into the standard name of the target network interface according to the interface identification information of the target network interface.
