8. Click the Add button to create a new DHCP pool. For more information, see
Adding a New DHCP Pool on page 5-7.

functionality. The values associated to options are local to the pool with which they are associated.
For more information, see Configuring DHCP Global Options on page 5-9.
10. Click the DDNS button to configure a DDNS domain and server address used with the list of available
pools. For more information, see Configuring DHCP Server DDNS Values on page 5-10.

(by clicking the Options button) only after the options are defined.
12. Click Apply to save changes to the screen. Navigating away from the screen without clicking Apply

5.2.1.1 Editing the Properties of an Existing DHCP Pool
The properties of an existing pool can be modified to suit changing network requirements.
To modify the properties of an existing pool:
1. Select Services > DHCP Server from the main menu tree.
2. Select an existing pool from those displayed (within the Network Pool field) and click the Edit button.
3. Modify the name of the IP pool from which IP addresses can be issued to client requests on this
interface.
4. Modify the Domain name as appropriate for the interface using the pool.
5. Modify the NetBios Node used with this particular pool. The NetBios Node could have one of the
following types:
•A b-broadcast (broadcast node) broadcasts to query network nodes for the owner of a NetBIOS
name.
•A p-peer (peer-to-peer node) uses directed calls to communicate with a known NetBIOS name
server, such as a Windows Internet Name Service (WINS) server, for the IP address of a NetBIOS
machine.
•A m-mixed is a mixed node that uses broadcasted queries to find a node and queries a known
p-node name server for the address.
•A h-hybrid is a combination of two or all of the nodes mentioned above.
6. Change the name of the boot file used for this pool within the Boot File parameter.
7. From the Network field, use the Associated Interface drop-down menu to modify (if necessary)
the switch interface used for the newly created DHCP configuration. Use VLAN1 as a default interface
if no others have been defined.
8. Additionally, define the network IP Address and Subnet Mask used for DHCP discovery and
requests between the DHCP Server and DHCP clients.
9. Within the Lease Time field, define one of the two kinds of leases the DHCP Server assigns to its
clients:
NOTE The network IP address and subnet mask of the pool are required to match the
addresses of the layer 3 interface for addresses to be supported on that interface.
