Embodiment Construction

[0053] Aiming at the problem in the prior art that the normal service of the network device is interrupted and the reliability of the network device is affected by the whole machine reset when the whole machine reset is not required, the embodiment of the present invention provides a method for resetting the network device. structured as figure 2 shown. The inventor found through research that whether the network device needs to reset the whole machine or reset the CPU can be determined according to whether the software and hardware are abnormal, and the abnormality of the hardware is usually the abnormality of the power supply clock. Therefore, compared to such figure 1 The network equipment shown is equipped with a power clock monitoring device to monitor whether the power clock is abnormal. In the network equipment, the CPU and the business module share the power clock. If the reset signal is received, the CPU and the business module share the power clock When the power s...

Abstract

The invention discloses a network equipment reset method and device. The method comprises the steps that a CPLD receives a reset signal sent by a reset signal generator; whether the reset signal is a thermal reset signal or not is determined; if it is determined that the reset signal is a thermal reset signal, whether complete machine reset is carried out on network equipment or a CPU is reset is determined according to whether a complete machine reset mark is stored in a software reset register and / or a power supply clock monitoring reset register or not. According to the technical scheme, it can be ensured that when only CPU reset is needed and complete machine reset is not needed, the network equipment can continue normal services, and the reliability of the network equipment can be ensured.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for resetting network equipment. Background technique [0002] With the rapid development of network technology, network devices are becoming more and more popular, commonly used are routers, switches, etc., network devices usually have a reset function, as follows figure 1 The switch shown is described as an example. There are two kinds of switch resets: cold reset and warm reset: cold reset is the reset of the switch from the power-off state to the power-on state, and is used to reset the whole machine, that is, to reset each device in the switch (for example, the central processing unit (Central Processing Unit) , CPU), Complex Programmable Logic Device (Complex Programmable Logic Device, CPLD), business module, etc.) to reset; hot reset means that the switch resets the whole machine or resets the CPU through the reset command or the reset button wh...
