Configuring LAN Adapter Interfaces

This task describes how to configure up to eight LAN adapter interfaces. To do this task, use the Configure Network Interface Parameters--Basic Options page on the Network tab.

Before you start, ask your network administrator if the computer being configured has access to a DHCP server. DHCP, or Dynamic Host Configuration Protocol, automatically assigns an IP address and configures TCP/IP every time you start the computer. DHCP is especially useful for "mobile" computing.

Note: You can configure no more than one DHCP LAN interface. If you opt to configure a DHCP interface, you may switch the "dynamic" aspect of this TCP/IP configuration on and off as desired by checking or unchecking the Mobile box on the Basic subtab of the Network tab.

Also ask your administrator if you are in a dynamically updatable zone. If so, DDNS, the Dynamic Domain Name Server, enables the client computer to dynamically and directly register its name and address mappings in the DDNS tables. This eliminates the need for network administrators to manually perform the updates.

Once you know the configuration options available to you, configure your LAN adapter interfaces as follows:

  1. Select the Network tab.

  2. Select the Basic subtab.

  3. Select a LAN adapter from the Interface to Configure list box.

  4. Under Configuration Options, check the Enable Interface box. This runs TCP/IP on the selected LAN adapter the next time you restart your computer.

  5. Do one of the following:

  6. Repeat these steps to configure additional LAN interfaces.

  7. Click OK to exit and save your entries.

Any information specified on this tab is saved in the SETUP.CMD file.
