if the first bad packet rate is larger than a first preset bad packet rate, judging a line with a fault in the network fault prevention system according to the network equipment corresponding to the first bad packet rate, and sending an alarm;
and if the second bad packet rate is greater than a second preset bad packet rate, judging that the port corresponding to the second bad packet rate has a fault and sending an alarm.
8. The network management method according to claim 3, wherein after the step of determining the failure of the network failure prevention system based on the second parameter data and issuing an alarm, further comprising:
determining the fault duration according to the fault of the network fault prevention system;
and if the duration is greater than the preset duration value, sending an alarm to be linked to a preset mailbox.
9. A vehicle comprising a network failure prevention system as claimed in claim 1 or 2, a memory, a processor, and a computer program stored on the memory and executable on the processor, the computer program, when executed by the processor, implementing the steps of the network management method as claimed in any one of claims 3 to 8.
10. A storage medium, characterized in that the storage medium has stored thereon a computer program which, when being executed by a processor, carries out the steps of the network management method according to any one of claims 3 to 8.
