Embodiment Construction

[0059] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0060] figure 2 It shows the location of the LACP entity in the switching system. After the link aggregation is successful, the LACP entities at both ends will save the protocol information of each member port in real time to the memory such as the high-end memory under normal operation conditions (this section of data is saved after the device is restarted). can be read and remain unchanged), when the underlying operating system notifies the LACP entity that the system needs to prepare for a hot start, the LACP entity saves the current protocol information of each port to t...

Abstract

The invention provides a link aggregation abnormity recovery method, an LACP (Link Aggregation Control Protocol) message processing method and exchange equipment. The link aggregation abnormity recovery method comprises the steps that the home-end exchange equipment receives an LACP message that is sent by the opposite-end exchange equipment and carries a request link protection event, and the home-end exchange equipment shuts down a receiving timer of the LACP message. According to the link aggregation abnormity recovery method and the exchange equipment, the receiving timer of the LACP message is shut down after the LACP message carrying the request link protection event is received, so that the equipment cannot detect a port of an opposite end to be unavailable due to the fact that the opposite-end equipment conducts abnormal events such as warm start and cannot send a data packet, normal forwarding of data cannot be influenced, and key network service can be influenced less.

Description

technical field [0001] The present invention relates to the field of data communication, in particular to a link aggregation abnormal recovery method, an LACP message processing method and switching equipment Background technique [0002] With the rapid development of network data transmission technology, users have higher and higher requirements for network reliability. Non-stop forwarding (NSF, None Stop Forwarding) is an important technology to improve the reliability of data transmission equipment. [0003] Link Aggregation Control Protocol (LACP, Link Aggregation Control Protocol) (IEEE Std802.3ad-2000) is an indispensable and important Layer 2 protocol in switching equipment. To achieve high reliability of NSF on switching equipment, two The guarantee of layer forwarding is essential. The LACP protocol bundles multiple physical links together to form a logical link, thereby achieving the purpose of doubling the link bandwidth. At the same time, these bundled links ca...
