Embodiment Construction

[0036] Aiming at the problems in the prior art that link faults are not found in time and the confirmation process is cumbersome, the VSF-based link fault detection method provided by the embodiment of the present invention sets the timeout duration of the port to zero after receiving the heartbeat message, and passes Compare the judgment of the timeout duration with the preset duration threshold to determine whether the link is faulty. The flow process of the inventive method is as figure 2 As shown, the method is applied to the network device in the VSF, and the execution steps of the method are as follows: including:

[0037] Step 201, receiving a heartbeat message sent by the opposite end from the port on which the link negotiation of the network device is successful;

[0038] Here, the network device enables the port to be UP, and the network device performs VSF link negotiation through the port. After the negotiation is successful, the VSF link is established, and the ...

Abstract

The invention discloses a VSF-based link fault detection method and a device. The method comprises the steps of receiving a heartbeat message sent by an opposite terminal from a port where link negotiation of a network device succeeds; acquiring destination port information of the heartbeat message, and setting the timeout duration of a port corresponding to the destination port information to bezero; traversing ports of the network equipment according to a first preset period, and determining whether the timeout duration of the ports exceeds a preset duration threshold; and if the timeout duration of the first port exceeds the preset duration threshold, determining a link fault corresponding to the first port. According to the method of the invention, rapid detection of the fault link can be realized without depending on an acknowledgement message, the process is simple, and the message interaction amount is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a link detection method and device based on a virtual switching fabric (Virtual Switching Fabric, VSF). Background technique [0002] VSF is a device-level vertical virtualization technology. By connecting multiple low-cost box devices as remote line cards to the main device, it achieves the purpose of expanding interface density and centralized control and management. [0003] For VSF system topology, please refer to figure 1 , the VSF system includes a main control device (Fabric Control, FC) and multiple port expansion devices (Fabric Extender, FE). The FC may be a single device, or may be performed by a virtual switching unit (Virtual Switch Unit, VSU) composed of multiple devices. The FC is responsible for the calculation of the protocol, the generation and delivery of table items, and the FE device is only responsible for data forwarding. FCs and FEs are...
