The DHCP Server Manager interface

You can start the DHCP Server Manager in the following ways:

• Double-click on the DHCP Server Manager icon in the System Administration window on the Desktop.

• Start SCOadmin by entering scoadmin on the command line, and then select Networking → DHCP Server Manager.

• Enter scoadmin DHCP Server Manager on the command line (or an abbreviation of this such as scoadmin DHCP).

Depending upon the selection made in the View menu, the main screen of the DHCP Server Manager shows global entries, subnet entries, client entries, user classes, vendor classes, or user-defined options that you have configured. Use View → Expand to examine the complete details for a selected entry in the list, and View → Collapse to display just its name and description. You can also expand and collapse individual entries by double-clicking on them. You can expand and collapse all entries using View → Expand All and View → Collapse All.

With the DHCP Server Manager, you can perform the following tasks:

• 
  Add user-defined DHCP options which can be configured for any subnet, client, class or globally.

• 
  Establish global DHCP options that apply to all clients. Identical options configured specifically for subnets, individual clients or classes override global options.

• 
  Configure the subnets on your network for DHCP service by assigning address pools to the subnets, establishing lease parameters and assigning DHCP configuration options that are specific to particular subnets.

• 
  
  Establish sets of DHCP options known as user classes and vendor classes which are supplied to DHCP clients requesting them.

• 
  Configure individual DHCP clients with a static IP address and unique configuration options.

• 
  Configure DHCP server parameters such as the location of the Address Allocation Server (AAS), initial lease reservation time, and option overloading.
