Create a DNS Group Object

Use the following procedure to create a new DNS group object in CDO:

Procedure

Step 1

In the CDO navigation bar on the left, click Objects > FDM Objects.

Step 2

Click the blue plus button to create an object.

Step 3

Click FTD > DNS Group.

Step 4

Enter an Object Name.

Step 5

(Optional) Add a description.

Step 6

Enter the IP address of a DNS server. You can add up to six DNS servers; click the Add DNS Server. If you want to remove a server address, click the delete icon.

Note	The list is in priority order: the first server in the list is always used, and subsequent servers are used only if a response is not received from the servers above it. Although you can add up to six servers, only the first 3 servers listed will be used for the management interface.

Step 7

Enter the Domain Search Name. This domain is added to hostnames that are not fully-qualified, for example, serverA instead of serverA.example.com.

Step 8

Enter the amount of Retries. The number of times, from 0 to 10, to retry the list of DNS servers when the system does not receive a response. The default is 2. This setting applies to DNS groups used on the data interfaces only.

Step 9

Enter the Timeout value. The number of seconds, from 1 to 30, to wait before trying the next DNS server. The default is 2 seconds. Each time the system retries the list of servers, this timeout doubles. This setting applies to DNS groups used on the data interfaces only.

Step 10

Click Add.
