Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] The stacking link fault handling method provided by the present invention is as follows: image 3 Shown:

[0039] see image 3 , image 3 It is a flow chart of a stacking link fault handling method provided by the present invention. This method is applied to member devices in a ring stack system, such as image 3 As shown, the process may include the following steps:

[0040]Step 301, when it is detected that the stack link connected to the device fails, enable the stack link failure delay (Link Down Delay) function for the faulty stack link, set the device to enter the fast forwarding state of Link Down Delay protection, and construct the The first broadcast message describing the faulty stack link is broadcast in the ring stack syste...

Abstract

This application provides a stacking link fault handling method and device. In the present invention, the member devices in the stacking system enable the Link Down Delay function when detecting that the stacking link connected to the device fails, and construct the first broadcast message to broadcast in the ring stacking system, so that other member devices will receive The faulty stack link described in the first broadcast message is regarded as an open circuit, and the forwarding data is recalculated for packet forwarding. At the same time, when receiving the first broadcast message sent by the peer connected to the faulty stack link The recorded forwarding data for message forwarding is used as backup forwarding data, and the forwarding data is recalculated for message forwarding on the premise that the faulty stack link described in the received first broadcast message is open, which can eliminate the When the Link Down Delay function is enabled, the packet is forwarded correctly to avoid the problem of unreachable packets.

Description

technical field [0001] The present application relates to network communication technologies, and in particular to a stacking link fault handling method and equipment. Background technique [0002] Multiple switching devices that support stacking can be connected to each other through stacking links to form a "joint device". This "joint device" is called a stacking system (Stacking), and each switching device that makes up the stacking system is called a member Device (Slot). After multiple member devices form a stack system, the stack system becomes a whole in terms of management and use. In other words, users can manage and use the stack system as a single device. Such as figure 1 In the ring stacking system shown, member devices Slot1, Slot2...Slot6 are connected through stacking links to form the ring stacking system, and the ring stacking system is managed and used as a whole. [0003] In a stack system, the stack link connection relationship between member devices ...
