5.2.1.1 Editing the Properties of an Existing DHCP Pool
The properties of an existing pool can be modified to suit the changing needs of your network.
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.
Lease Time
(dd:hh:mm)
When a DHCP server allocates an address for a DHCP client, the client is assigned
a lease (which expires after a designated interval defined by the administrator). The
lease time is the time an IP address is reserved for re-connection after its last use.
Using very short leases, DHCP can dynamically reconfigure networks in which there
are more computers than there are available IP addresses. This is useful, for
example, in education and customer environments where MU users change
frequently. Use longer leases if there are fewer users.
Domain
Displays the domain name for the current interface.
