Configuring DNS Servers

Configuring DNS Servers

This chapter includes the following sections:

DNS Policies

Cisco UCS Central supports global DNS policies defining the DNS server. Registered Cisco UCS domains choosing to define DNS management globally within that domain's policy resolution control will defer DNS management to its registration with Cisco UCS Central.

Configuring a DNS Policy

Before You Begin

Before configuring a DNS policy in a domain group under the Domain Group root, this policy must first be created. Policies under the Domain Groups root were already created by the system and ready to configure.

Procedure
    Step 1   On the menu bar, click Operations Management.
    Step 2   In the Navigation pane, expand Domain Groups > Domain Group root.
    Step 3   Under the Domain Groups root node, do one of the following choices:
    • To configure the policy in the domain group root, click Operational Policies.
    • To configure the policy in a specific domain group, expand the node for that domain group and click Operational Policies.
    Step 4   In the Navigation pane, click Operational Policies.
    Step 5   In the Work pane, click DNS.
    Step 6   In the Actions area, click Create and complete all applicable fields.

    For Operational Policies under the Domain Group root node, it is not necessary to click Create to complete all applicable fields.

    Name Description

    Create button

    Creates an instance of the policy that will be used by all Cisco UCS domains included in the selected domain group.

    Import button

    Allows you to import the policy from one of the Cisco UCS domains registered with Cisco UCS Central.

    Delete button

    Deletes the instance of the policy defined for the selected domain group.

    After you delete the policy, it remains greyed-out until you click Save. When you do so, Cisco UCS Central deletes the policy and any configuration data you may have specified. While you can create a new instance of the policy later, you cannot restore the configuration data from a deleted instance.

    To cancel the delete request, click Reset.

    Domain field

    The domain name associated with the Domain Name Server (DNS) server.

    Filter button

    Allows you to filter the data in the table. When you apply a filter, this button name changes to Filter (on).

    Add DNS Server button

    Allows you to add a DNS to the selected domain group.

    Properties button

    Displays detailed properties for the object selected in the table.

    Delete button

    Deletes the object selected in the table.

    DNS IP column

    The IP address of the DNS server.

    Step 7   Click Save.

    Deleting a DNS Policy

    Deleting a DNS policy will remove all DNS server settings within that policy.

    Procedure
      Step 1   On the menu bar, click Operations Management.
      Step 2   In the Navigation pane, expand Domain Groups > Domain Group root.
      Step 3   Under the Domain Groups root node, do one of the following choices:
      • To configure the policy in the domain group root, click Operational Policies.
      • To configure the policy in a specific domain group, expand the node for that domain group and click Operational Policies.
      Step 4   In the Navigation pane, click Operational Policies.
      Step 5   In the Work pane, click DNS.
      Step 6   In the Actions area, click Delete.

      A policy that is deleted will inherit its settings from its domain group's parent until it is reconfigured.

      Step 7   Click Save.

          Step 3   Under the Domain Groups root node, do one of the following choices:
          • To configure the policy in the domain group root, click Operational Policies.
          • To configure the policy in a specific domain group, expand the node for that domain group and click Operational Policies.

          Step 7   Click Save.
