Changing the advanced downstream DNS configuration settings for a network

If advanced downstream DNS configuration mode is enabled and you have the service role, you can use the Networks Network View page to directly access the UNIX IP address management for any forward facing network you created, including [hcp_system].

Changes made in advanced downstream DNS configuration mode need to be manually applied to all nodes added to the system. HCP generates a system log message that alerts you if you need to add new nodes to the zone file. If your changes are compatible with new system versions, all modifications carry over through future system upgrades.

Procedure

  1. On the Networks Network View page, click the network for which you want to change the advanced downstream DNS configuration settings.

  2. In the Zone Entry field, make all of your necessary changes.

  3. In the Forward Zone field, make all of the your necessary changes.

  4. Perform one of the following actions:

    • If you want to discard your changes, click Reset Zone Entry and File. This resets the network to its default downstream DNS configuration settings.

    • If you want to keep your changes, click Update Settings.

    After you click Update, HCP performs a syntax validation check and administers your changes to the HCP system. Before they can take effect however, a system reboot is required.

    During the reboot, if the HCP system finds any issues with your DNS configuration, it reverts all forward facing networks to their default downstream DNS configuration value. If this occurs, advanced downstream DNS configuration mode remains enabled but your changes are not saved.

Next steps

After your HCP system reboots, it’s recommended that you test your DNS access to HCP. If you do not want to keep your changes, click Reset Zone Entry and File in the Advanced DNS Downstream Configuration panel.
