Problems solved by technology

[0002] In some complex network devices that include multiple switching chips connected to each other (or in a network that includes multiple switches connected to each other), if a port of a switching chip (or switch) is finally connected to the same switch through a non-gateway device Another port of the chip (or switch), and the switch chip (or switch) has no STP (Spanning Tree Protocol, Spanning Tree Protocol) protocol, the broadcast packet will be infinitely broadcast in the switch chip (or switch), forming a network storm , so that the performance of the switching chip (or switch) is completely consumed, and it can no longer work normally

Embodiment 1

[0129] See Figure 4A , is a schematic diagram of the architecture of a specific application scenario provided by the embodiment of the present invention, such as Figure 4A As shown, in this embodiment, the target switching device includes switch 2 and switch 3, switch 2 is connected to ports P0 and P1 of switch 1 through ports P4 and P5 respectively, and is connected to port P12 of switch 4 through ports P6 and P7 respectively connected to P13; switch 3 is connected to ports P2 and P3 of switch 1 through ports P8 and P9 respectively, and is connected to ports P14 and P15 of switch 4 through ports P10 and P11 respectively. Switches 1 to 4 all support port aggregation configuration.

[0130] In this embodiment, a user (such as a network administrator) can issue an equalization mode setting command to Switch 2 and Switch 3, and configure port aggregation on ports P0-P3 of Switch 1 and ports P12-P15 of Switch 4 respectively.

[0131] When switch 2 (or switch 3) receives the ba...

Embodiment 2

[0139] See Figure 4B , is a schematic diagram of the architecture of another specific application scenario provided by the embodiment of the present invention, such as Figure 4B As shown, in this embodiment, the target switching device includes switch 2 and switch 3, switch 2 is connected to ports P0 and P1 of switch 1 through ports P4 and P5 respectively, and is connected to port P12 of switch 4 through ports P6 and P7 respectively It is connected to P13; switch 3 is connected to ports P2 and P3 of switch 1 through ports P8 and P9 respectively, and is connected to ports P14 and P15 of switch 4 through ports P10 and P11 respectively. Switch 1 supports port aggregation configuration, and switch 4 does not support port aggregation configuration.

[0140] In this embodiment, the user (such as a network administrator) can set the hot standby mode to switch 2 and switch 3, and configure ports P0 and P1, P2 and P3 of switch 1, ports P4 and P5 of switch 2 and Ports P8 and P9 of s...

Embodiment 3

[0151] See Figure 4C , is a schematic diagram of the architecture of another specific application scenario provided by the embodiment of the present invention, such as Figure 4C As shown, in this embodiment, the target switching device includes switch 2 and switch 3, switch 2 is connected to the hot-swap device through ports P4 and P5 respectively, and switch 3 is connected to ports P2 and P3 of switch 1 through ports P7 and P8 respectively , the switch 2 is connected to the port P9 of the switch 3 through the port P6. Switches 1 to 3 all support port aggregation configuration; switches 2 and 3 reserve a mechanism for obtaining access device type selection; devices 1 and 2 are non-switches.

[0152] In this embodiment, a user (such as a network administrator) can issue an independent mode setting instruction to the switch 2 and the switch 3 .

[0153] When the switch 2 and the switch 3 receive the independent mode setting instruction, respectively obtain the device type of...

Abstract

The present application provides a broadcast packet forwarding method, device, electronic device, and readable storage medium. The method includes: performing a cascading operation according to the cascading configuration information; The ports connected to non-cascading member devices all join the same aggregation group; when a broadcast packet is received from a member port of the aggregation group, it is refused to forward the broadcast packet through other member ports of the aggregation group. This method can improve networking reliability.

Description

technical field [0001] The present application relates to communication technology, and in particular to a broadcast packet forwarding method, device, electronic equipment and readable storage medium. Background technique [0002] In some complex network devices that include multiple switching chips connected to each other (or in a network that includes multiple switches connected to each other), if a port of a switching chip (or switch) is finally connected to the same switch through a non-gateway device Another port of the chip (or switch), and the switch chip (or switch) has no STP (Spanning Tree Protocol, Spanning Tree Protocol) protocol, the broadcast packet will be infinitely broadcast in the switch chip (or switch), forming a network storm , so that the performance of the switching chip (or switch) is completely consumed, and it can no longer work normally. Contents of the invention [0003] In view of this, the present application provides a broadcast packet forwa...
