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.
To change the advanced downstream DNS configuration settings for a network:
1.On the Networks►Network View page, click on 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. For more information on the Zone Entry field see, Configuring DNS for HCP.
3.In the Forward Zone field, make all of the your necessary changes. For more information on the Forward Zone field, see Configuring DNS for HCP.
4.Perform one of the following actions:
oIf you want to discard your changes, click on the Reset Zone Entry and File button. This resets the network to its default downstream DNS configuration settings. For more information on the downstream DNS configuration default settings, see Changing the default downstream DNS configuration settings for a network.
oIf you want to keep your changes, click on the Update Settings button.
Once you click on the Update button, 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.
Once 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 on the Reset Zone Entry and File button in the Advanced DNS Downstream Configuration panel.
