Stacking is to logically change a plurality of switches supporting stacking characteristics into one device by connecting a plurality of switches together through a stacking line, and the core idea of the stacking is to connect a plurality of devices together through stacking ports, virtualize the devices into one 'distributed device' after necessary configuration. The virtual switching technology can be used for integrating hardware resources and software processing capacity of a plurality of devices, and realizing cooperative work, unified management and uninterrupted maintenance of the plurality of devices.
The vlan isolation technology divides a physically formed Local Area Network (LAN) into different logical subnets according to a specific strategy, isolates data link layer broadcast messages within the logical subnets to form respective broadcast domains, and each logical subnet is a Virtual Local Area Network (Virtual LAN). Each terminal device of the switch accessing and supporting the vlan belongs to a specific vlan, and the terminal devices in different vlans cannot directly communicate through a data link layer.
As shown in fig. 1, it exemplarily shows a structural diagram of an existing scheme stacking group, the stacking group includes two stacking member devices, which are a stacking member device 1 and a stacking member device 2, and a switch LSW (local area network switch) with a two-layer network in the middle, there are 4 stacking links between the stacking member device 1 and the stacking member device 2, the stacking member device 1 has four stacking ports, port1, port2, port3 and port4, the stacking member device 2 has four stacking ports, port1 'port 2', port3 'and port 4', and the LSW has four relay ports, port1 ", port 2", port3 ", port 4", port5 ", port 6", port7 "and port 8. As shown in fig. 1, port1, port1 ', port 5' and port1 'belong to the same link, port2, port 2', port6 'and port 2' belong to the same link, and other links are not described one by one.
In order to simplify the forwarding flow of the message, in the existing scheme, after receiving the stack message encapsulated with the mac address and the vlan sent by the stack member device 1, the LSW forwards the stack message to the stack port corresponding to the second device according to the mac address and the vlan, after receiving the stack message, the stack port of the second device determines whether the stack message needs to be processed by itself by determining the mac address and the vlan, where in the existing scheme, the mac address encapsulated by each stack member device is fixed, the mac address of each stack port of the stack member device 1 is mac1, the mac address of each stack port of the stack member device 2 is mac2, that is, the source mac addresses of the stack messages sent from the four stack ports of the stack member device 1 are mac1, the destination mac addresses are mac2, and similarly, the source mac addresses of the stack messages sent from the four stack ports of the stack member device 2 are mac2, the destination mac addresses are mac1, so as to simplify the process of forwarding the stack packet, but because there are multiple stack links, in order to avoid forwarding errors, the existing scheme sets different vlans for each link to perform vlan isolation, and sets different vlans for each trunk port of a switch in the two-layer network, so that the switch can accurately forward the stack packet to the stack port of the same vlan of another stack member device, that is, the port1, port1 ", port 5" and port1 'belong to the same link and the same vlan, and the stack packet sent through the port1 can be received by the switch only through the port1 ", and forwarded to the port 1' of the stack member device 2 through the port 5".
However, in a real environment, setting a vlan to a port of each stack member device actually sets a vlan to each link, setting a vlan to each link actually sets a vlan to each trunk port of the switch, and setting a vlan to each trunk port of the switch, the trunk port does not allow the vlan to pass stack messages for other vlans, and flexibility of intermediate two-layer network deployment is limited to a large extent.

It should be noted that the following embodiments may be referred to, referred to or combined with each other, and the description of the same terms, similar features, similar implementation steps and the like in different embodiments is not repeated.

In the embodiment of the application, the relay port is a port on a switch, and each reference mac address in the mac forwarding table and the relay port corresponding to the reference mac address are determined in the following manner:
after receiving a certain stack message, searching whether a reference mac address identical to a source mac address of the stack message exists in a mac forwarding table, if the reference mac address identical to the source mac address does not exist, indicating that the stack message is received for the first time, learning the stack message is required, recording the source mac address of the stack message as a new reference mac address, acquiring a relay port for receiving the stack message, determining that the relay port for receiving the stack message is a relay port corresponding to the new reference mac address, and recording the new reference mac address and the relay port corresponding to the new reference mac address in the mac forwarding table.
In the mac forwarding table of the embodiment of the present application, a relay port corresponding to each reference mac address may represent two layers: one layer means: the mac address of the stack port connected with the relay port is the reference mac address; the other layer means: if the destination mac address of a received stack packet is the same as the reference mac address, the stack packet can be forwarded to the stack port corresponding to the destination mac address through the relay port.
In the embodiment of the application, after receiving the stack message sent by the first device, the destination mac address is searched in a pre-established mac forwarding table, and if the mac forwarding table includes the reference mac address with the same destination mac address, the relay port corresponding to the reference mac address is determined to be the forwarding port.
In addition, it is to be noted that, in the embodiments of the present application, each stack port and each relay port belong to the same vlan, and vlan isolation is not set for the stack port and the relay port.
Step S203, the stack packet is forwarded to the stack port corresponding to the destination mac address in the second device through the forwarding port.
And the stack port of the first device, the stack port of the second device and the relay port are all in the same vlan.
After the forwarding port is determined, the embodiment of the application forwards the stack packet to the stack port corresponding to the destination mac address in the second device through the forwarding port, and after the second device receives the stack packet, the second device strips the encapsulated ethernet frame and sends the ethernet frame to the next module.
According to the embodiment of the application, the relay port corresponding to the reference mac address which is the same as the mac address can be inquired in the mac forwarding table, and the relay port is determined to be the forwarding port, so that the two-layer network can be effectively passed through, instead of implementing vlan isolation on each port on a stacking link, and the flexibility of deployment of the intermediate two-layer network is improved.

The length of the mac address is 48 bits (6 bytes), a plurality of stacking links exist between the first device and the second device in the embodiment of the present application, the fixed bits and the variable bits of the mac information of each stacking port of the first device and the second device can be determined according to the number of the stacking links, and the mac address is divided into the fixed bits and the variable bits.
In this embodiment, the fixed bits refer to the same bits of the mac addresses of different stack ports of the same device, and the changed bits refer to bits of the mac addresses of different stack ports of the same device that are changed.
Specifically, assume the maximum link number of bits64, i.e. the number of links between the first device and the second device is at most 64, due to 26>=64, and thus it can be determined that the number of bits that need to be changed is 6, that is, the last 6 bits of the mac address are changed bits, and since the length of the mac address is 48 bits, it can be determined that the fixed bits of the mac address are 48-6=42, that is, the first 42 bits of the mac address are fixed bits.
It should be noted that the fixed bit in the embodiment of the present application may be used as an identification mark of the mac addresses of the first device and the second device, that is, the stack ports of the first device have the same fixed bit, the stack ports of the second device have the same fixed bit, and the first device or the second device may be determined by identifying the fixed bit of the mac address.
The fixed bit in the embodiment of the application can be used as the identifier of the mac address of the first device and the second device, and the specific numerical values of the fixed bit of the first device and the second device are different.
The change bit can be used as the unique identifier of each stack port, the stack ports of the same device can be distinguished by setting different change bits for each stack port, so that the mac address formed by the fixed bit and the change bit can be distinguished from each stack port, the mac address of each stack port in network transmission is different, and normal forwarding of stack messages can be guaranteed in the same vlan.
After the fixed bit and the change bit of the mac address of each stack port of the first device are determined, the mac address is configured for each stack port of the first device.
Specifically, the mac address is usually expressed by 12 16 bits, and assuming that the maximum number of links between the first device and the second device is 16, the change bit is determined to be 4 bits, and the 4 binary bits are 1 16 bits, so that it can be determined that only the last 16 bits are required to be changed, i.e., the fixed bit is the last 16 bits, and the fixed bit is changed from 0 of 16 bits to f of 16 bits, and if the fixed bit of the mac address of the first device is 00-01-00-02-10-0, the mac addresses that can be configured for the 16 stack ports of the first device are respectively 00-01-00-02-10-01, 00-01-00-02-10-02, …, 00-01-00-02-10-0f, and each stack port has the same fixed bit and different change bits, the mac address composed of the fixed bit and the variable bit is unique, and the mac address of each stack port can be distinguished.

and determining fixed bits of the mac addresses of the stack ports of the first device and the second device according to the changed bits of the mac addresses of the stack ports of the first device and the second device.
After the number of links between the first device and the second device is obtained, the number of mac addresses required to be allocated to the stacking ports of the first device and the second device is determined according to the number of links.
Specifically, assuming that the number of links between the first device and the second device is 16, it can be determined that the first device and the second device have 16 stack ports, respectively, that is, 16 mac addresses need to be allocated to the stack ports of the first device, and 16 mac addresses need to be allocated to the stack ports of the second device.
After determining the number of mac addresses, the changed bits of the mac addresses of the respective stack ports of the first device and the second device are determined according to the number of mac addresses. Specifically, continuing with the above example, the number of mac addresses allocated to the first device is determined to be 16, and if the mac addresses are expressed in 16-ary bits, only the last bit is required to be changed, i.e., the fixed bit is the last 16-ary number.
The mac address comprises 12 16-ary numbers in 16-ary expression, the last 16-ary number is a change bit, and the first 11 16-ary numbers of the fixed bit can be determined.
Similarly, the mac address is expressed as a 48-bit binary number, and the last 4-bit 2-ary number is a change bit, which determines that the first 44 bits of the fixed bit are binary numbers.

Specifically, if the mac address is expressed in a 16-system, the change bit is the last 16-system number, the fixed bit is the first 11-bit binary number, the fixed bit of each stack port of the first device is set to be 00-01-00-02-10-0 according to a preset rule, the fixed bit of each stack port of the second device is set to be 00-01-00-03-10-0, the fixed bits of the two are changed from 0 in the 16-system to f in the 16-system, the mac address of each stack port of the first device can be determined to be 00-01-00-02-10-01, 00-01-00-02-10-02, …, 00-01-00-02-10-0f by combining the fixed bits and the change bits, and the mac address of each stack port of the second device is 00-01-00-03-10-01, 00-01-00-03-10-02, …, 00-01-00-03-10-0 f.
