Managing the Domain Name System (DNS) Server

A Domain Name System (DNS) server is required for the IBM® WebSphere® DataPower® XC10 Appliance as DNS lookup services are used for communication. You are required to specify the DNS server during the appliance initialization.

Before you begin

You must be assigned the Appliance administration permission to perform these steps.

About this task

A DNS server is required for the appliance to function correctly. Your DNS servers must have forward and reverse DNS entries for the range of IP addresses being managed by WebSphere DataPower XC10 Appliance. WebSphere DataPower XC10 Appliance uses the derived host name from the reverse lookup during deployment of a virtual system. If a reverse lookup fails because no host name is defined, then the deployment fails because it requires a host name rather than just an IP address.

Procedure

  1. Navigate to the Settings panel.
    • From the menu bar at the top of the WebSphere DataPower XC10 Appliance user interface, navigate to Appliance > Settings.
    • From the Home panel, click the Customize settings link in the Step 1: Set up the appliance section.
  2. Expand Domain Name Servers.
  3. Optional: Click the <ip address> to modify an existing DNS server.
  4. Select Click to add to add a new DNS server. A DNS server is configured during the initialization of the appliance.
  5. Optional: Click the remove icon (the remove icon) to remove a DNS server.

Results

After successfully completing these steps, you have defined a DNS server to be used for lookups during communication.

What to do next

You can also set DNS servers with the command line interface. See Using the command line interface to run operations on your appliance for more information.
