35 EKI-9500 Series User Manual
Pool Configuration
Use the DHCP Server Pool Configuration page to edit pool settings or to configure
additional settings for existing manual and dynamic pools. The additional settings on
this page are considered advanced parameters because they are not typically used
or configured. The fields that can be configured depend on the Type of Binding that is
selected. The fields that do not apply to the selected binding type are disabled.
Network Base
Address The network portion of the IP address. A DHCP client can be offered
any available IP address within the defined network as long as it has
not been configured as an excluded address (for dynamic pools only).
Network Mask The subnet mask associated with the Network Base Address that sep-
arates the network bits from the host bits (for dynamic pools only).
Client Name The system name of the client. The Client Name should not include
the domain name. The function is only available for Manual pools.
Hardware Address
Type The protocol type (Ethernet or IEEE 802) used by the client's hard-
ware platform. This value is used in response to requests from
BOOTP clients. The function is only available for Manual pools.
Hardware Address The MAC address of the client. The function is only available for Man-
ual pools.
Client ID The value some DHCP clients send in the Client Identifier field of
DHCP messages. This value is typically identical to the Hardware
Address value. In some systems, such as Microsoft DHCP clients, the
client identifier is required instead of the hardware address. If the cli-
ent's DHCP request includes the client identifier, the Client ID field on
the DHCP server must contain the same value, and the Hardware
Address Type field must be set to the appropriate value. Otherwise,
the DHCP server will not respond to the client's request. The function
is only available for Manual pools.
Host IP Address The IP address to offer the client. The function is only available for
Manual pools.
Host Mask The subnet mask to offer the client. The function is only available for
Manual pools.
Lease Expiration
Mode Indicates whether the information the server provides to the client
should expire.

Enable: Allows the lease to expire. If you select this option, you
can specify the amount of time the lease is valid in the Lease
Duration field.

Disable: Sets an infinite lease time. For Dynamic bindings, an
infinite lease time implies a lease period of 60 days. For a Man-
ual binding, an infinite lease period never expires.
Lease Duration The number of Days, Hours, and Minutes the lease is valid. This field
cannot be configured if the Lease Expiration Mode is disabled.
Default Router
Address The IP address of the router to which the client should send traffic.
The default router should be in the same subnet as the client. To add
additional default routers, use the DHCP Server Pool Configuration
page.
DNS Server Address The IP addresses of up to two DNS servers the client should use to
resolve host names into IP addresses. To add additional DNS servers,
use the DHCP Server Pool Configuration page.
