Note: You cannot use set and enable on the same command line.
Attribute Flags
Command are described as:
● Required--The attribute is required for the object, and usually syntactically positional on
the create command line. You must set the attribute or accept its default, and you can
modify the value. You cannot use the unset keyword to set a required attribute to
undefined. Trying to do so returns the error message 386 - Required attribute cannot be
deleted.
● Optional--The attribute is optional and does not require a value. You can set and reset the
attribute, and you can use the unset keyword to make it undefined.
● Read-only--The attribute is immutable and read-only. You can use the gett keyword with
the attribute, but you cannot set or unset it. Trying to set or unset a read-only attribute
returns the error message 385 - Read-only attribute cannot be modified.
Saving Your Changes
With new commands introduced in Network Registrar 6.2, nrcmd applies the changes you make
immediately. (Commands introduced in Network Registrar 6.2 are listed in Release Notes). With
the commands from prior releases, the CLI waits for one of these events to occur before it saves
your changes to the database:
● Invoking the save command
● Exiting from nrcmd
● Reloading a server
● Adding a resource record or host to a zone
Refreshing and Clearing the CLI Cache
The CLI caches many configuration objects that it reads. If multiple users are making changes
simultaneously, one CLI instance might have cached an out of date version of an object. The
session cache refresh command causes the CLI to clear its local cache of all unmodified objects,
forcing it to reread objects from the configuration database. The session cache clear command
forces the CLI to clear all cached data, whether or not unsaved changes were made.
Navigation Keys
Table 1-2 lists keyboard navigation key combinations that are useful when entering nrcmd
commands.
