Method for processing port failures based on LACP and LACP terminal

Abstract

The embodiment of the invention discloses a method for processing port failures based on a link aggregation control protocol LACP and an LACP terminal. The method comprises the following steps: a first terminal obtains the failure information of the first port in a first port aggregation group; the first terminal adopts the second port in the first port aggregation group as a failure information transmission port; and the first terminal adopts the second port to transit a failure transfer message to a fourth port which is corresponding to the second port in a second port aggregation group of the second terminal so that the second terminal stops to transfer the message of a third port which is corresponding to the first port in the second port aggregation group, wherein the failure transfer message is an LACP message, and the reserved field in Terminator information field of the LACP message carries the failure information. The scheme of the embodiment of the invention improves the failure transfer performance through the optimization of the LACP, does not need depending on other protocols or technologies, and cannot be limited by the network.

Description

technical field [0001] The invention relates to the technical field of communication. Specifically, it relates to a link aggregation control protocol (Link Aggregation Control Protocol, LACP)-based port fault handling method and LACP terminal. Background technique [0002] Link aggregation refers to a method of bundling a group of physical ports together as a logical interface to increase bandwidth. The bundled physical ports are also called multi-port load balancing groups. LACP based on the IEEE802.3ad standard is a protocol for realizing link dynamic aggregation and de-aggregation. LACP exchanges information with the peer end through Link Aggregation Control Protocol Data Unit (Link Aggregation Control Protocol Data Unit, LACPDU). [0003] In LACP, the port at both ends of the link that sends the message is called the local end (Actor), and the port that receives the message is called the peer end (Partner). The two parties notify the peer end of their system by exchang...

Problems solved by technology

However, some operators' devices (such as H3C S8500 / 7800 / 6500 switches) do not support BFD, and there are few devices that support the linkage between BFD and interface management. Therefore, the application scenarios of this method are limited, and the device hardware configuration, CPU The processing power requirements are also higher

[0007] Another solution in the existing technology is to add WDM devices between switching devices, and use the fault transmission technology of WDM devices to speed up link switching. However, the implementation of WDM devices is not standardized at present, and the networking environment of the intermediate network also restricted

For WDM equipment, Link-state Pass Through (LPT) or Automatic Laser Shutdown (ALS) technology is currently mainly used. However, LPT is a proprietary protocol that cannot be connected to third-party equipment, and Other network devices do not necessarily support this protocol, and for the ALS standard, each manufacturer may have different support for the standard
