Abstract
A stacking system that includes multiple computer network devices (such as a switch or a router) is described. This stacking system may include: an active computer network device that implements software for control protocols and user configuration of the stacking system, and a standby computer network device that provides switchover backup for the active computer network device. During operation of the stacking system, when a switchover from the active computer network device to the standby computer network device occurs, at least the standby computer network device performs an action based at least in part on differences between system control tables for the active computer network device and the standby computer network device, wherein the action comprises: reprograming at least part of the system control tables; reprogramming at least part of hardware in the stacking system; or downloading at least the part of the system control tables to the hardware.
