In GS/SURE linkage mode, the ping command is issued against the IP address of the actual interface of the remote system at regular interval. If a transfer path failure is detected or a failure notification is received from the remote system, the route is switched and a reporting message will be output. Then, communication is continued using other transfer path.
This function is used exclusively for GS/SURE linkage mode. In Fast switching mode, when the virtual interface activates, the process will be executed automatically. NIC switching mode is not capable of using this function.
