Abstract

The present invention provides a method and a switch for handling stack splitting, wherein the method includes: when the stack splits, the first switch sends its own first configuration information to the second switch through the third switch outside the stack , the first configuration information includes at least a first domain identifier of the first switch and a first stack identifier of the first switch; the first switch receives the second switch through the third switch second configuration information, the second configuration information includes at least a second domain identifier of the second switch and a second stack identifier of the second switch; when the first domain identifier and the first When the identifiers of the two domains are the same, and the first stack identifier and the second stack identifier meet a preset condition, the service port on the first switch is closed. The invention can solve the chaotic problem of route calculation after the stack split.

Description

technical field [0001] The invention relates to a stack split processing technology, in particular to a stack split processing method and a switch. Background technique [0002] Stacking is a software virtualization technology. Its core idea is to connect multiple devices together, perform necessary configurations, and virtualize them into one device. Using this virtualization technology can integrate the hardware resources and software processing capabilities of multiple devices to achieve collaborative work, unified management and uninterrupted maintenance of multiple devices. [0003] A link failure between stacked devices will cause one stack to become multiple new stacks. In order to improve the availability of the system, a protection mechanism is needed when a stack splits, which can detect multiple stacks that exist simultaneously in the network and perform corresponding processing to minimize the impact of stack splits on services. [0004] At present, through LAC...
