Abstract

The present invention discloses a cross-device aggregation group rapid convergence method, and a cross-device aggregation group rapid convergence device which are applied to a vertical stack system. The vertical stack system comprises an internal link and a plurality of nodes connected with the internal link, and is configured with a cross-device aggregation group. When a member port of the cross-device aggregation group goes wrong (Down), the node at the member port constructs an interruption message notification message, and the interruption message notification message is sent to the other nodes in the vertical stack system via the internal link to update the software / hardware tables of the member ports of the aggregation group. According to the present invention, the problem in the prior art that the speeds of the nodes of the vertical stack system of perceiving the link events at the ports of the cross-device aggregation group are slower is solved, and the convergence of the cross-device aggregation group is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for fast convergence across equipment aggregation groups when a node port in a vertical stacking system fails (Down). Background technique [0002] In the communication field, vertical stacking technology has the advantages of improving transmission performance and reliability. In the actual application process, the vertical stacking system further supports cross-device link aggregation, but for the cross-device link aggregation of the vertical stacking system, each node in the system is required to sense the link event of the port of the corresponding aggregation group. When it is detected that a port is Down, it is necessary to update the software and hardware table of the aggregation group member port, that is, the global aggregation group entry maintained by the software and the aggregation group member port entry on the MAC chip, so as not to affect subs...
