Tells DHCP how many bytes in a lease IP address to use when forming
in-addr.arpa names. The server forms names in the in-addr zone by
prepending dns-host-bytes of IP address (in reverse order) to the
reverse zone name. If unset, the server synthesizes an appropriate
value based on the scope's subnet size.
dynamic-bootp bool default = disabled
Controls whether the server will accept dynamic BOOTP
requests for this scope. Dynamic BOOTP requests are BOOTP requests
that do not match a reservation, but could be satisfied from the
available lease pool. To use this feature you must also enable
bootp.
embedded-policy obj(0)
Displays the embedded policy for a scope.
failover-backup-allocation-boundary ipaddr
Sets the IP address allocation boundary for a backup server in a
failover relationship.
If the allocate-first-available attribute is set, the backup
server allocates IP addresses in descending order from this
boundary.
If the allocate-first available attribute is unset or set to 0,
the boundary used for allocating addresses is half the
distance between the first and last IP address configured in the
ranges for this scope. If no IP addresses are available
below this boundary, the first IP address available above this
boundary is used.
free-address-config nameref(AddrTrapConfig)
Identifies which trap captures unexpected free address events
on this scope.
ignore-declines bool default = false
Determines whether the server reacts to server DHCPDECLINE
messages that refer to one of the scope's IP addresses.
If enabled (true), the DHCP server ignores all declines that
refer to an IP address in this scope. If disabled, the DHCP server
sets to UNAVAILABLE every IP address referred to in this scope.
Default is false (disabled).
ping-clients bool
If this attribute is not set, or is unset, then the DHCP server
attribute ping-clients controls whether the server should attempt
to ping an address before offering a lease. If enabled (true),
this attribute also indicates a ping timeout.
if ping-clients is set and ping-clients for the scope is unset,
then the server pings an address as if it was set in the scope.
If ping-clients is enabled or disabled for a scope, then
for that scope the setting of ping-clients at the server level has
no meaning.
If not specified for the scope, the DHCP server's 'ping-clients'
is used as the default.
