7.6 Configuring DHCP/BOOTP IP Addressing
7.6.1 Static IP Addressing for BOOTP Clients
To define static IP addressing, specify a specific IP address for a specific MAC
address as follows:
1. Start the GUI by entering the following command:
$ DHCPGUI
2. Click the Nodes tab.
3. Choose [New Record].
4. Enter the host name (Name).
5. Enter the MAC/hardware address. For example, 08:00:20:3f:12:4b.
6. Choose Hardware Type from Key Parameters. Enter the type of network on
which the node resides. Enter the hardware type using the symbol or the
type number as shown in Table 7–6.
7. Choose [Host IP Address].
8. Enter the Host IP address of the host computer for this node.
9. As appropriate, enter information for Network, Lease, Time, BOOTP,
NetBIOS, X Window, TCP, IP, and Link parameters. For more information
about these parameters, refer to Section 7.5.3.4.
10. Choose Update from the File menu to update the server with the new
configuration.
7.6.2 Static IP Addressing for DHCP Clients
Select static addressing if you want to assign a specific IP address with a
permanent lease time to a DHCP client, and you do not want the client to be able
to release this IP address. Also, select static addressing if you need to select an
IP address that is not part of any IP address pool.
Selecting an IP address from outside an IP address pool allows the server to
specify a permanent mapping between a DHCP client’s MAC address and the
desired IP address. A client can reuse and release any address within an IP pool.
To configure a specific, permanent address for a DHCP client, do the following:
1. Start the GUI by entering the following command:
$ DHCPGUI
2. Click the Server/Security tab.
3. Choose Active IP Snapshot, then choose [New Record].
4. Enter the MAC address.
5. Enter the MAC type.
6. Enter the MAC address length.
7. Enter an IP address that does not belong to any IP address pools.
8. Enter -1 (infinite lease) for the lease expiration.
9. Enter the server IP address.
10. If you want a name associated with the client, specify the client’s host name
and domain name.
