In DHCP Pool Configuration mode, the administrator can configure the
address space and other parameters to be supplied to DHCP clients. By
default, the DHCP server assumes that all addresses specified are available for
assignment to clients. Use the ip dhcp excluded-address command in Global
Configuration mode to specify addresses that should never be assigned to
DHCP clients.
To configure a dynamic DHCP address pool, configure the following pool
properties using the listed DHCP pool commands:
• Address pool subnet and mask – network
• Client domain name – domain-name
• Client DNS server – dns-server
• NetBIOS WINS Server – netbios-name-server
• NetBIOS Node Type – netbios-node-type
• Client default router – default-router
• Client address lease time – lease
Administrators may also configure manual bindings for clients using the host
command in DHCP Pool Configuration mode. This is the most often used
for DHCP clients for which the administrator wishes to reserve an ip address,
for example a computer server or a printer. A DHCP pool can contain
automatic or dynamic address assignments or a single static address
assignment.
To configure a manual address binding, configure the pool properties using
the DHCP pool commands listed below. It is only necessary to configure a
DHCP client identifier or a BOOTP client MAC address for a manual
binding. To configure a manual binding, the client identifier or hardware
address must be specified before specifying the host address.
• DHCP client identifier – client-identifier
• BOOTP client MAC address – hardware-address
• Host address – host
• Client name (optional) – client-name
