Manually clear the DNS cache of LTM or BIG-IP DNS Servers.

DNS deployment to managed DNS/DHCP Servers in your F5 pool will automatically clear the DNS cache on LTM and BIG-IP DNS Servers. However, if you need to clear the DNS cache manually, you can do so from the F5 Service Configuration page of the Address Manager user interface.

To manually clear the DNS cache of an LTM or BIG-IP DNS Server:

  1. From the configuration drop-down menu, select a configuration.
  2. Select the Servers tab. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Configuration information page.
  3. Under Servers, click an LTM or BIG-IP DNS Server name. The Details tab for the server opens.
  4. Click the server name menu button and select F5 Service Configuration. The Configure Remote Services page opens.
  5. From the Service Type drop-down menu, select Clear DNS Cache. Address Manager queries the LTM or BIG-IP DNS Server and returns the current values for the service settings.
  6. Under General Settings, set the following parameters:
    • Virtual Servers—(LTM only) from the drop-down menu, select a Virtual Server associated with your LTM server.
      Note: The values of Cache Partition, Cache Type, and Cache Name will change depending on the selected Virtual Server.
    • Listeners—(BIG-IP DNS Servers only) from the drop-down menu, select the listener configured on your BIG-IP DNS Server.
      Note: The values of Cache Partition, Cache Type, and Cache Name will change depending on the selected listener.
    • Clear DNS Cache—select the Clear DNS Cache check box to ensure the DNS cache will be cleared on the associated LTM or BIG-IP DNS Server.
  7. Click Update.

Address Manager clears the DNS cache of the selected LTM or BIG-IP DNS Server.
