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:
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.
