the second alert action includes: the host judges whether the feedback condition has the first address or the second address, if so, the host judges that the core server corresponding to the first address or the core switch corresponding to the second address is abnormal equipment and reports the first address or the second address; if not, the host judges that the core server corresponding to the first address and the core switch corresponding to the second address are both the abnormal equipment, and reports the first address and the second address.
9. The utility model provides a network detects and switching system based on net gape is bound, be applied to core server and with the host computer that core server connects, core server with dispose the switch link between the host computer, core server with dispose the core switch between the switch link, the host computer with dispose the net gape between the switch link, the net gape the switch link with the core switch connects gradually, the net gape all disposes the net gape address, the host computer disposes the host computer address, a serial communication port, the net gape address all binds on the host computer address, the system includes:
the device comprises an initialization module, a network detection module and a processing module;
the initialization module is used for selecting a network port corresponding to any one network port address as a main network port and setting a detection item;
the network detection module is used for acquiring a target address and configuration information and controlling the host to execute a detection action on the target address according to the detection item to obtain a detection result;
the processing module is used for controlling the host to execute a switching action and an alarming action according to the detection result and the configuration information;
the switching action comprises: the host detects whether a network port connected with the switch link corresponding to the detection result is the main network port, and if so, the host switches the main network port;
the alert action includes: and the host reports the target address and the configuration information corresponding to the detection result.
10. A computer-readable storage medium, wherein a computer program is stored on the computer-readable storage medium, and when being executed by a processor, the computer program implements the steps of the network interface binding-based network detection and handover method according to any one of claims 1 to 8.
