Problems solved by technology

[0006] 1. It must be based on the hardware circuit in the network device, resulting in low versatility in restoring the default configuration and additional implementation costs;
[0007] 2. The buttons are easily damaged, so it is easy for the network equipment to fail to restore the default configuration;
[0008] 3. Need to occupy the GPIO pins that are already very scarce, which will easily lead to insufficient GPIO pin resources of the CPU

Embodiment Construction

[0066] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0067] figure 2 It is a schematic diagram of using a port to form a loop to trigger a network device to restore a default configuration in an embodiment of the present invention. like figure 2 As shown, there are two ports ( figure 2 Take UNI1 and UNI2 as examples) are selected as designated ports.

[0068] When it is necessary to trigger the network device to restore the default configuration, UNI1 and UNI2 can be connected to form a loop;

[0069] Afterwards, when the network device is powered on and started, the CPU can cooperate with the switching chip to perform the following processing:

[0070] 1. The CPU instructs the switch chip to isolate the ports UNI1~n from each other, and knows that it needs to report all the received packets whose ...

Abstract

The invention provides a method for triggering network equipment to recover default configuration and a device. According to the invention, two specified ports form a loop as a triggering condition for the network equipment to recovery default configuration, so that various defects caused by adopting a button as the triggering condition can be overcome. Furthermore, the two specified ports are allowed to be used according to the method of the default configuration only after the loop which is formed by the two specified ports is detected to be released, so that a network storm caused by the error reservation of the loop after the default configuration is recovered.

Description

technical field [0001] The invention relates to configuration technology of network equipment, in particular to a method for triggering network equipment to restore default configuration and a device for triggering network equipment to restore default configuration. Background technique [0002] Configurations in network devices (including system configurations and service configurations) play a vital role in the normal operation of network devices and services. In practical applications, the configuration of the network device can be changed according to different operating environments and business environments. In some cases, it is necessary to restore the changed current configuration to the default configuration of the network device. [0003] The so-called default configuration refers to the configuration provided by the manufacturer for the network device. Network devices usually have non-volatile random access memory (Non-Volatile Random Access Memory, NVRAM) such as...
