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 present invention provides a link aggregation abnormality recovery method, an LACP packet processing method, and a switching device, wherein the link aggregation abnormality recovery method includes: the local switching device receives the request link sent by the peer switching device A Link Aggregation Control Protocol (LACP) packet of a path protection event; the local switching device closes a receiving timer of the LACP packet. The abnormality recovery method and the switching device of the above link aggregation close the receiving timer of the LACP message after receiving the LACP message carrying the request link protection event, so that the device will not be restarted due to the hot start of the peer device. It detects that the peer port is unavailable due to abnormal events such as failure to send data packets, which will not affect the normal forwarding of data, thereby ensuring that key services on the network are less affected.

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) (IEEEStd802.3ad-2000) is an indispensable and important Layer 2 protocol in switching equipment. To achieve high reliability of NSF on switching equipment, Layer 2 The guarantee of 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 can a...
