By default, no DHCP address
pool is created.
Specifying IP address ranges for a DHCP address pool
You can configure both static and dynamic address allocation mechanisms in a DHCP address pool. For
dynamic address allocation, you can specify either a primary subnet with multiple address ranges or a
primary subnet with multiple secondary subnets for a DHCP address pool. You cannot configure both.
Specifying a primary subnet and multiple address ranges for a DHCP address pool
Some scenarios need to classify DHCP clients in the same subnet into different address groups. To meet
this need, you can configure DHCP user classes and specify different address ranges for the classes. The
clients matching a user class can then get the IP addresses of a specific address range. In addition, you
can specify a common address range for the clients that do not match any user class. If no common
address range is specified, such clients fail to obtain IP addresses.
If there is no need to classify clients, you do not need to configure DHCP user classes or their address
ranges.
Follow these guidelines when you specify a primary subnet and multiple address ranges for a DHCP
address pool:
