Problems solved by technology

However, there are two problems in the method of using the transmission device for relaying: one problem is that when a link between the transmission device and the peer stacking device fails, the local stacking device cannot perceive the link between the transmission device and the peer stacking device. The state of the link, at the local end, the link still participates in the forwarding route selec

Embodiment approach

[0094] The present invention has two implementation modes, one is to use the maximum number of retries to detect the links corresponding to the first detection port and the second detection port of the stacking device multiple times within the maximum number of retries, and according to the detection results Set the corresponding working state of the port, Figure 8 , 10 It is a flow chart of detecting the first detection port and the second detection port respectively by using this implementation method; the other is to use the maximum waiting time to test the first detection port and the second detection port of the stacking device multiple times within the maximum waiting time The corresponding links are detected separately, and the corresponding working status of the port is set according to the detection results. Figure 9 , 11 It is a flow chart of detecting the first detection port and the second detection port respectively by using the implementation method. next to...

Abstract

The invention provides a stacked link aggregation fault detection method and stacked devices, wherein the method comprises the following steps: periodically sending a KeepAlive message from a first detection port, if an ACK message which aims at the KeepAlive message and is sent by an adjacent stacked device is not received within the maximum retry time or the maximum retry time, determining thata link passing through the first detection port has a fault, then setting the first detection port into the state of not participating in message forwarding; and periodically waiting for receiving the KeepAlive message at a second detection port, if the KeepAlive message sent by the adjacent stacked device is received within the maximum retry time or the maximum retry time, determining that a link passing through the second detection port has a fault, then setting the second detection port into the state of not participating in message forwarding. Through the application of the method and device provided by the invention, stacked devices can span over transmission facilities, so that the stacked devices can be respectively placed at the positions which are far enough.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a stacking link aggregation fault detection method and a stacking device. Background technique [0002] Data Center is an integrated IT application environment formed by the concentration of data, and it is the center for providing various services, data processing, data storage and data exchange. Data centralization puts forward higher requirements for data security. In order to deal with the impact of natural disasters such as fires, floods, earthquakes and man-made disasters such as misoperations and viruses on enterprises, data center disaster recovery (Disaster Recovery) is applied to realize data security. Remote disaster backup has become the development trend of data protection. [0003] At present, in the networking of the data center, Layer 2 network interconnection has become a future development trend. The scope of the Layer 2 network is usually limited...
