Pool Summary

Use the DHCP Pool Summary page to view the currently configured DHCP (Dynamic Host Configuration Protocol) server pools and to add and remove pools. A DHCP server pool is a set of network configuration information available to DHCP clients that request the information..

To access this page, click System > Advanced Configuration > DHCP Server > Pool Summary in the navigation menu.

Use the buttons to perform the following tasks:

To add a pool, click Add and configure the pool information in the available fields. Then click Submit.
To remove one or more pools, select each entry to remove and click Remove. You must confirm the action before the pools are removed.

DHCP Pool Summary Fields

Field	Description
Name	The name that identifies the DHCP server pool.
Type of Binding	The type of binding for the pool. The options are: Manual : The DHCP server assigns a specific IP address to the client based on the client's MAC address. This type is also known as Static. Dynamic: The DHCP server can assign the client any available IP address within the pool. This type is also known as Automatic. Undefined: The pool has been created by using the CLI ( command-line interface), but the pool information has not been configured.
Network	For a Manual pool, the host IP address to assign the client. For a Dynamic pool, the network base address.
Lease Time	The amount of time the information the DHCP server allocates is valid.
When you click Add, the Add DHCP Server Pool page opens and allows you to configure the following DHCP pool settings:
Name	The name that identifies the DHCP server pool.
Type of Binding	The type of binding for the pool. The options are: Manual: The DHCP server assigns a specific IP address to the client based on the client's MAC address. Dynamic: The DHCP server can assign the client any available IP address within the pool. The binding type you select determines the fields that are available to configure.
Network Base Address	(Dynamic pools only) 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.
Network Mask	(Dynamic pools only) The subnet mask associated with the Network Base Address that separates the network bits from the host bits.
Client Name (optional)	(Manual pools only) The system name of the client. The Client Name should not include the domain name.
Hardware Address Type	(Manual pools only) The protocol type (Ethernet or IEEE 802) used by the client's hardware platform. This value is used in response to requests from BOOTP clients.
Hardware Address	(Manual pools only) The MAC address of the client.
Client ID	(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.
Host IP Address	(Manual pools only) The IP address to offer the client.
Host Mask	(Manual pools only) The subnet mask to offer the client.
Lease Expiration Mode	Whether the information the server provides to the client should expire. The options are: 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.
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 (optional)	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 (optional)	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.

If you change any of the parameters, click Submit to apply the changes to the system. If you want the switch to retain the new values across a power cycle, you must save the configuration.
