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.
Pool Name
Displays the name of the IP pool from which IP addresses can be issued to DHCP
client requests on the current interface. The pool is the range of IP addresses
available.
Network
Displays the network address for the clients.
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.
