Embodiment Construction

[0022] In the following description, for purposes of illustration rather than limitation, specific details such as specific system architectures, interfaces, and techniques are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0023] figure 1 It is a schematic diagram of an application scenario of a method for handling a link aggregation port failure provided by an embodiment of the present invention. The method for processing link aggregation port failures provided by the embodiments of the present invention can be used as a new method for processing link aggregation port failures in a networking system with port aggr...

Abstract

The invention relates to a method and a device for processing a fault of a link aggregation port. A transferring chip of a line clamp to which a faulted physical port belongs receives a fault report message when the faulted physical port in a link aggregation group is faulted, wherein the fault report message carries port information of the faulted physical port; an inform message is sent to a transferring chip of a line clamp to which other physical ports except for the faulted physical port belong in the link aggregation group, wherein the inform message carries the port information of the faulted physical port; and the transferring chip of the line clamp to which other physical ports belong can update the stored state of the faulted physical port according to the port information. According to the embodiment of the invention, when a certain physical port in the link aggregation group is faulted, the transferring chip can broadcast the fault message of the port, so that the fault processing time is shortened, and an aim of preventing packet loss caused by fault of the port is fulfilled.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for processing link aggregation port failures. Background technique [0002] Link aggregation (Link Aggregation) is a method of bundling a group of physical ports together as a logical interface to increase bandwidth, also known as multi-port load balancing group (Load Sharing Group) or port aggregation (Trunk). By establishing a link aggregation group (Link Aggregation Group) between two devices (such as device A and device B), it can provide higher communication bandwidth and higher reliability. This improvement does not require hardware upgrades, and Redundant protection is also provided for the communication between the two devices. [0003] When using a link aggregation group, if a physical port fails, you need to delete the failed physical port from the trunk, that is, you need to update the trunk member information. The following takes the failure of ...
