The switching time (error detection time) is about 10 seconds.
However, the switching time is occasionally affected by the ATM switch.
The online NIC is monitored in 5 seconds intervals by the transmission path monitoring daemon, and the standby NIC is monitored in 300 seconds intervals. The connection state monitoring of the transmission path will judge that the transmission path is abnormal, if Link down is detected twice consecutively. If abnormalities are detected by the online NIC, the standby NIC will change to online, and to be in the state where it cannot be used if abnormalities are detected by the standby NIC. As for the error rate monitoring of the communication packet, the switching is done upon the error rate of the input and output packet reaching 50%.
