Embodiment Construction

[0056]In order to perform effective loopback detection on aggregated links, the technical solution provided by the embodiment of the present invention will provide a more comprehensive solution than ordinary loopback detection. In the scheme, when the loopback detection of the aggregated link starts, a loopback detection message uniquely representing the aggregated link will be generated, and sent out from each member port of the aggregated link in turn, and will be included in the message when sending Insert the PORT ID (port identification) of the corresponding port. If the message is received at any member port, it means that the aggregation link has a loop. According to the PORT ID of the port in the message content and the port PORT ID of the receiving message In this way, the specific member ports and ring formation types of the aggregated link that form the loop can be determined. Specific embodiments of the present invention will be described below in conjunction with ...

Abstract

The invention discloses a method and equipment for detection processing of loopback of an aggregation link. The method comprises the following steps: sending a identifier carrying the aggregation link from each member port in the aggregation link and a first loopback detection message of the identifier of the member port for sending the first loopback detection message; receiving the identifier carrying the aggregation link at the each member port in the aggregation link and a second loopback detection message of the identifier of the member port for sending the second loopback detection message; and determining whether to form a loop or not according to the identifiers of the aggregation links in the first loopback detection message and the second loopback detection message. The method and the equipment can timely process the loopback detection processing problem in the data communication equipment.

Description

technical field [0001] The invention relates to data communication technology, in particular to a method and equipment for loopback detection and processing of aggregated links. Background technique [0002] With the growth of data traffic, high availability has increasingly become one of the most important features of high-performance networks. Currently, link aggregation is widely used in link-level high-availability technologies. It aggregates multiple physical ports together to form a logical port to realize the load sharing of outbound / incoming traffic among member ports. The switch decides which member port to send the message from according to the port load sharing policy, thereby increasing the chain road bandwidth. When the switch detects a link failure on one of the member ports, it will recalculate the port to send the message on the remaining member links according to the load sharing policy, and recalculate the port to send the message after the faulty port re...
