Method and device for detecting abnormal restart cause of AP equipment

Abstract

The invention discloses an abnormal restart reason detecting method and device of AP equipment. The method comprises that before that the AP equipment is restarted, a restart reason sign and a restart log corresponding to a restart reason in this time are written in a reserved memory; when the AP equipment is restarted, a virtual address of the reserved memory is obtained by mapping; restart log information in the reserved memory is backed up, and present serial-port printing information is recorded in real time; and the restart reason sign and the restart log in the reserved memory are read and stored. According to the method and device, concrete reasons for restart of the AP equipment can be determined, the fault positioning efficiency and accuracy of the AP equipment are improved greatly, and the stability of subsequent version iteration is guaranteed.

Description

technical field [0001] The invention relates to the field of wireless networks, in particular to a method and device for detecting abnormal restart causes of AP equipment. Background technique [0002] WLAN (Wireless Local Area Networks, wireless local area network) provides a wireless connection service of local area network, which can provide high-speed wireless data access in a small range, and is currently one of the more popular technologies in the IT (Information Technology, information technology) industry. First, it is also a popular wireless access method. [0003] Compared with the wired access method of the drive, the wireless LAN makes the use of the network more free, completely getting rid of the constraints of cables and port positions, and the wireless LAN has the advantages of being portable and easy to move, eliminating or reducing the complicated Network cabling, only need to place one or more AP (Access Point, access point) devices to establish a local a...

AI Technical Summary

Problems solved by technology

[0005] The AP device sometimes restarts during use. However, there is still no clear positioning solution for the reason for the restart.

Although some AP devices currently have functional modules for recording logs, for example, when the device kernel restarts abnormally, it will record logs, but the existing AP devices have a single function of recording system crash logs, and it is impossible to distinguish restarts in detail based on the logs recorded. , which affects the stability test and release of the version, thus affecting the iteration and stability of the later version
