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 ...
