DHCP Server Pool Options

Use the DHCP Server Pool Options page to configure additional DHCP pool options, including vendor-defined
options. DHCP options are collections of data with type codes that indicate how the options should be used.
When a client broadcasts a request for information, the request includes the option codes that correspond to
the information the client wants the DHCP server to supply.
To access the page, click System > Advanced Configuration > DHCP Server > Pool Options in the
navigation menu. The page displays the fields shown below only if DHCP pools are configured on the system.

DHCP Server Pool Configuration Fields (Continued)
Description
Manual pools only – The system name of the client. The Client Name should not include the domain
name. This field is optional.
Manual pools only – The protocol type (Ethernet [default] or IEEE802) used by the client's hardware
platform. This value is used in response to requests from BOOTP clients.
Manual pools only – The MAC address of the DHCP client.
Manual pools only – 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 client'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.
Manual pools only – The IP address to offer the client.
Manual pools only – This field specifies the subnet mask to be statically assigned to a DHCP client.
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 Manual binding, an infinite lease period never expires.
The number of Days, Hours, and Minutes the lease is valid. This field cannot be configured if the Lease
Expiration is disabled.
The IP address of the next server the client should contact in the boot process. For example, the client
might be required to contact a TFTP server to download a new image file. Use the buttons as follows:
Click this button to configure the Next Server Address field.
Click this button to reset the field to the default value.
Lists the IP address of each router to which the client(s) in the pool should send traffic. The default
router should be in the same subnet as the client.
Lists the IP address of each DNS server the client(s) in the pool can contact to perform address resolution.
Lists the IP address of each NetBIOS Windows Internet Naming Service (WINS) name server that is
available for the selected pool.
