Abstract

The invention provides a stack splitting processing method and a switch. The method comprises steps: when splitting happens to stack, a first switch sends first configuration information of the first switch to a second switch via a third switch outside the stack, wherein the first configuration information at least comprises a first field identifier of the first switch and a first stack identifier of the first switch; the first switch receives second configuration information of a second switch via the second switch, wherein the second configuration information at least comprises a second field identifier of the second switch and a second stack identifier of the second switch; and when the first field identifier and the second field identifier are the same, and the first stack identifier and the second stack identifier meet preset conditions, service ports on the first switch are closed. A routing calculation chaos problem after stack splitting can be solved.

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, Ethernet pr...
