| Dormant DHCP Reservation | It is used to delete reserved IP addresses that are inactive for specific days. The inactive means that a reserved IP address is not assigned because the host that has the MAC address of the reserved IP address did not request it. We called it "Dormant DHCP Reservation". |
| DHCP Failover Deadtime | It is the time in seconds to provide DHCP service for specific DHCP pools in a DHCP passive system.
If the passive system does not receive any response from an active system for this time, the passive system begins DHCP service for DHCP pools that was served by the active system. |
| Random Assignment | If it is enabled, a DHCP service assigns IP addresses in random order. If not, a DHCP service sequentially assigns. |
