ABSTRACT:
The present invention discloses a method for processing multiple active devices in a stacking system. In the method, each active device in a stacking system exchanges unique identity information with any another active device through a preconfigured Bidirectional Forwarding Detection (BFD) session when a stacking link in the stacking system is in failure, determines an active priority of its own by comparing unique identity information of its own with the unique identity information received; and the active device stops providing services as an active device when determining that the active priority of its own is not the highest priority. The present invention also discloses a member device in the stacking system. The present invention can solve the collision of multiple Active devices, and is applicable to both a stacking system including two member devices and a stacking system including more than two member devices.
