Compatibility judging method, device and network equipment for switching between active and standby main control boards

Abstract

The invention discloses compatibility judging network equipment, a compatibility judging method and a compatibility judging device for switching between active and standby main control boards and aims to solve the problem that service interruption time is prolonged in an active and standby main control board switching process because the judgment of the conventional software compatibility is incorrect. The method comprises the following steps of: judging whether a corresponding hot backup basic module is compatible or not; when the corresponding hot backup basic module is compatible, judging whether a corresponding hot backup entity mode is compatible or not according to the software edition number information of each corresponding hot backup entity module; and when the corresponding hot backup entity mode is compatible, determining to adopt a hot backup switching mode during the switching between active and standby main control boards. Hot backup switching cannot be performed on the hot backup basic module until a module which provides a hot backup mechanism is compatible and the hot backup entity module can be switched in a hot backup switching mode when the software edition numbers of the module are accordant. Therefore, a compatibility judging process in the embodiment of the invention is more correct and the service interruption time of the network equipment in the active and standby main control board switching process can be shortened effectively.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a compatibility judging method, device and network equipment for the switchover of main and standby main control boards. Background technique [0002] For network devices with important locations, in order to prevent single point failures, two main control boards need to be configured on such network devices, namely the active main control board (Master) and the standby main control board (Slave). Among them, the active main control board realizes the business communication with the external and service boards, and completes the normal functions of each module in the network equipment, and the standby main control board is the backup of the main main control board, and the main main control board runs normally. , the standby main control board does not communicate with the external and service boards. However, when the active main control board fails, in or...
