To configure DNS server settings for a data center

1. Prerequisites

   You must have the following information:

   • The IP address of the DNS server

   • The name of the domain, and associated credentials.

     Linux Bind: For TSIG authentication, you need the TSIG key and TSIG private files.

     Windows DNS: For GSSAPI authentication, you need the user name and keytab file.

   • A test host name and IP address for performing a test operation. The test operation validates the specified DNS configuration.

2. Navigate

   	Settings (menu bar) > Infrastructure > Details View
   	Expand the data center > Access Profile
   	Click the Windows DNS or Bind tab. DNS servers already added for the data center are listed in the table. You can remove or add a new DNS server.

3. To add a new DNS server for the data center click + Add New DNS.

4. Specify the IP address for the DNS server and select the purpose, either Rehearsal or Production.

5. Add one or more domains for the DNS server:

   • Fill in the domain name and the authentication type. For TSIG, browse to the key and private files. For GSSAPI, enter the user name and browse to the keytab file.

   • Enter a test host name and IP address and select Test. If the test is successful, that is the DNS configuration is validated, the Add button is enabled.

   • Select Add.
