Configuring the DHCP Server
7.5 Using DHCP GUI to Configure DHCP
7.5.3.1.1 Configuring a subnet You do not have to change every value for the
parameters in the Subnets tab.
To configure a subnet group using the Subnets tab, use the following procedure.
For a description of the subnet parameters, see Section 7.5.3.4.
1. Click the Subnets tab.
2. Choose [New Record].
3. Choose the Name parameter from the Name/ID Parameters menu.
4. Enter the name of the subnet configuration in the Value field. This name is
a tag for internal use of the DHCP server only. For more information, see
Section 7.5.3.4.1.
5. Choose Member of Group (optional). Enter the name of the include group that
the subnet group is joining. Any client that matches this entry will pull in
the parameters from the specified include group.
6. Set up key information:
a. Choose the net or subnet IP address.
Enter the net or subnet IP address that identifies the subnet portion of
the network.
b. Choose the vendor class (optional).
Enter the vendor class (for example, TCPVMS or JOIN) that identifies the
DHCP client vendor class to which this entry should apply. Note that you
can have multiple subnet entries for the same Net or Subnet IP Address
if they have different Vendor Class key values. If the entry should apply
to any vendor class or you are not using vendor classes leave the Vendor
Class field blank.
7. Choose from the lists of DHCP parameters on the drop-down list.
Different lists of DHCP parameters are available on the drop down list.
Choose either BASIC DHCP Parameters or DHCP Parameters.
8. 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.
9. Choose Update from the File menu to update the server with the new
configuration.
The new configuration takes effect immediately.
7.5.3.1.2 Removing a Subnet Record To remove a subnet record:
1. Click the Subnets tab.
2. Choose DHCP Parameters from the drop-down list.
3. Choose the subnet record you want to delete.
4. Click Delete.
Changes to the database take effect immediately.
