| Auto failback | Indicates that the failover unit hands back control to the master automatically when the master starts to respond after a hardware failure, turns off its configuration and services and return to standby status. |
| Keep-alive internal | The interval after which the master and failover unit communicate to make sure that the master is still working. The default is 1 second. In non-congested networks, we recommend a very short interval. It is undetectable in terms of system performance. |
