Assigns an order to scopes for allocating IP addresses. Acceptable
scopes, with the highest allocation priority, grant IP addresses
until the addresses are exhausted.
You can mix scopes with an allocation-priority along with those
without a priority in the same network. In this case, scopes with
allocation priorities are examined for acceptability before those
scopes with no allocation-priority. Lower numeric values have
higher priorities, but an allocation-priority of 0 (the default) has
no priority.
If this attribute is not set, or is unset or 0, then the
DHCP priority-address-allocation attribute controls the priority
of the scope. If the DHCP priority-address-allocation attribute is
set, and allocation-priority for the scope is unset, then the
allocation-priority for the scope is the network number of the
scope.
If you explicitly set allocation-priority, then, for that scope,
the DHCP setting of priority-address-allocation has no meaning.
backup-pct percent
Determines the percentage of available addresses that the main server
sends to the backup server. If you define this value using the
scope command, make sure you define it on the main server. If you
define it on a backup server, it is ignored.
Used with the scope command, the backup-pct attribute overrides
the defined values on the failover pair for backup-pct and
dynamic-bootp-backup-pct. The attribute value defined with the scope
command becomes the value used for this scope, whether or not this
scope supports dynamic-bootp.
If you set the value to zero (0), the backup server receives no
addresses. Since 0 is a significant value, once you set this value,
you must unset it for the scope to use the failover pair's values for
backup-pct or dynamic-bootp-backup-pct.
Note: If the failover pair is configured to use load balancing, the
backup-pct is ignored and 50% is used.
bootp bool default = disabled
Controls whether the server accepts BOOTP requests. If you want
clients to always receive the same addresses, you must reserve
IP addresses for all your BOOTP clients.
deactivated bool
Controls whether a scope extends leases to any clients. A deactivated
scope does not extend leases to any clients. It treats all addresses
in its ranges as if they were individually deactivated.
description string
Describes the scope.
dhcp bool default = enabled
Controls whether the DHCP server accepts DHCP requests for this
scope. Disable DHCP if you want a scope to use BOOTP exclusively
or you want to deactivate the scope temporarily.
