Each namespace has a set of commands associated with them that will be described later in this section.
Each command is either a variable or a function:
• Variables
Sets or gets a variable value. Variables are often, but not always, stored in the profiles that can be
saved (see section on profiles).
The following attributes are defined for all Variables:
o Read Permission
Defines permissions required to see the current state of the variable.
o Write Permission
Defines permissions required to modify the state of the variable.
o Default
Defines the initial state of the variable as well as the state set when resetting to factory
defaults. If this value is NULL, it means the variable does not have a default and will not get
reset when going to factory defaults.
o Priority
The priority determines the order that a variable gets restored during profile or factory
default restoration. The higher the priority number, the earlier the variable will get
restored in the restore sequence. If this value is “-1”, it means the variable does not get
restored.
