Saving your configuration
As you apply page settings, the system applies the values to the running configuration. Most Management Console configuration pages include an Apply button for you to commit your changes. When you click Apply, the Management Console updates the running configuration. Your changes are only written to disk when you save your configuration.
To save your changes, click Save to Disk to save the changes to disk.
A red outline around a control indicates that the field is required. You must specify a valid entry for all of the required controls on a page before submitting the changes to the system.
