This read-only value reports the type of a DHCP global pool, and any operation on it is tied to the related network address and mask objects or the related host address objects, meaning setting this object alone is treated as invalid; the only currently defined value, network(1), indicates a pool using automatic address allocation. An admin needs to configure the paired network/mask or host address objects together with this one, since the device rejects a change to this object made in isolation. For example, provisioning a new automatic-allocation pool requires setting this object to network(1) alongside the pool's network address and mask in the same operation.
