Understanding the CLI Level Hierarchy
The CLI hierarchy is a series of levels. Arranging commands in a hierarchy of levels provides a way to organize and group similar commands, provide different levels of security, and reduce the complexity and number commands and options presented to a user at one time.
When you start a command line session, you begin at the root level. This level can be password protected and provides access to high level status, a few diagnostic commands, and the file system level. Further device information and configuration are accessed via the enable level.
The enable level can also be password protected and is the gateway to full configuration and management of the xPico Wi-Fi embedded device server. There are commands for gathering and effecting all elements of device status and configuration, as well as commands that take you to additional levels. For instance, tunnel specific status and configuration is found under the "tunnel" level, and network specific status and configuration commands are found under the "configuration" level.
Commands at the root level (see Figure A-2 Root Level Commands below) do not affect current configuration settings and are not displayed initially. If you type ?, you will see the login sub- commands. These commands provide diagnostic and status information only.

Configuration Using XML
The xPico Wi-Fi embedded device server provides an Extensible Markup Language (XML) interface that you can use to configure xPico Wi-Fi embedded device servers. Every configuration setting, excluding XML import and export, that can be issued from the xPico Wi-Fi Web Manager and CLI can be specified using XML.
The XPico Wi-Fi embedded device server can import and export configuration settings as an XML document known as an XML Configuration Record (XCR). An XCR can be imported or exported via the CLI or the xPico Wi-Fi embedded device server filesystem. An XCR can contain many configuration settings or just a few. For example, it might change all of the configurable
