Specifies the name of the update configuration that determines
which forward zones to include in updates.
forward-zone-name dname
Designates an optional forward zone for DNS updates.
giaddr-as-server-id bool default = false
Enables the DHCP server to set the server-id option on a DHCPOFFER
and a DHCPACK to the giaddr of the incoming packet, instead of the
IP address of the server (the default action).
This causes all unicast renews to be sent to the relay agent instead
of directly to the DHCP server, and so renews arrive at the DHCP
server with option-82 information appended to the packet.
Some relay agents may not support this capability and, in some
complex configurations, the giaddr might not actually be an address
to which the DHCP client can send A unicast packet. In these cases,
the DHCP client cannot renew a lease, and must always perform a
rebind operation (where the DHCP client broadcasts a request instead
of sending a unicast to what it believes is the DHCP server).
grace-period time default = 5m
Defines the length of time between the expiration of a lease
and the time it is made available for reassignment.
inhibit-all-renews bool default = false
Causes the server to reject all renewal requests, forcing the client
to obtain a different address any time it contacts the DHCP server.
inhibit-renews-at-reboot bool default = false
Permits clients to renew their leases, but the server forces
them to obtain new addresses each time they reboot.
limitation-count int
Specifies the maximum number of clients with the same limitation-id
that are allowed to have currently active and valid leases.
offer-timeout time default = 2m
Instructs the server to wait a specified amount of time when it
has offered a lease to a client, but the offer is not yet accepted.
At the end of the specified time interval, the server makes the
lease available again.
packet-file-name string
Identifies the boot-file to use in the boot process of a client.
The server returns this file name in the 'file' field of its replies.
The packet-file-name cannot be longer than 128 characters.
packet-server-name string
Identifies the host-name of the server to use in a client's boot
process. The server returns this file name in the 'sname' field
of its replies. The packet-server-name field cannot be longer
than 64 characters.
packet-siaddr ipaddr
