[. . . ] When you click Restore, the access point will reboot. A reboot confirmation dialogue and follow-on rebooting status message will be displayed. Wait a minute or two for the reboot process to complete. Then try to access the Web User Interface as described in the next step; the Web User Interface will not be accessible until the access point has rebooted. Note 3. When the access point has rebooted, access the Web User Interface either by clicking again on one of the tabs (if the Web User Interface is still displayed) or by typing the IP address the Professional Access Point as a URL in the address field of the Web browser. Enter the URL for the access point as http://IPAddressOfAccessPoint. The Web User Interface displays the configuration settings restored from the backup file that you selected. Backup/Restore - 176 Professional Access Point Administrator Guide Command Line Interface In addition to the Web-based user interface, the Professional Access Point includes a command line interface (CLI) for administering the access point. The CLI lets you view and modify status and configuration information. From the client station perspective, even a single deployed Professional Access Point broadcasting its "network name" to clients constitutes a wireless network. Keep in mind that CLI configuration commands, like Web User Interface settings, can affect a single access point running in stand-alone mode or automatically propagate to a network of clustered access points that share the same settings. (For more information on clustering, see "Access Points" on page 43. For information on how to set an access point to stand-alone or cluster mode from the CLI, see "Set Configuration Policy for New Access Points" on page 39) This part of the Professional Access Point Administrator Guide introduces the interface and provides a complete description of classes and their associated fields: · · Class Structure, Commands, and Examples Class and Field Reference Class Structure, Commands, and Examples The following topics in this appendix provide an introduction to the class structure upon which the CLI is based, CLI commands, and examples of using the CLI to get or set configuration information on an access point or cluster of APs: · · Comparison of Settings Configurable with the CLI and Web User Interface How to Access the CLI for an Access Point · · · · Telnet Connection to the Access Point SSH2 Connection to the Access Point Quick View of Commands and How to Get Help Command Usage and Configuration Examples · · · Understanding Interfaces as Presented in the CLI Saving Configuration Changes Basic Settings Class Structure, Commands, and Examples - 177 Professional Access Point Administrator Guide · · · · · · · · · · · · · · · · · · Access Point and Cluster Settings User Accounts Status Ethernet (Wired) Interface Wireless Interface Security Enable/Configure Guest Login Welcome Page Configuring Multiple BSSIDs on Virtual Wireless Networks Radio Settings MAC Filtering Load Balancing Quality of Service Wireless Distribution System Time Protocol Reboot the Access Point Reset the Access Point to Factory Defaults Keyboard Shortcuts and Tab Completion Help CLI Class and Field Overview Comparison of Settings Configurable with the CLI and Web User Interface The command line interface (CLI) and the Web User Interface to the Professional Access Point are designed to suit the preferences and requirements for different types of users or scenarios. Most administrators will probably use both interfaces in different contexts. Some features (such as Clustering) can only be configured from the Web User Interface, and some details and more complex configurations are only available through the CLI. The CLI is particularly useful in that it provides an interface to which you can write programmatic scripts for access point configurations. Also, the CLI may be less resource-intensive than a Web interface. The following table shows a feature-by-feature comparison of which settings can be configured through the CLI or the Web User Interface, and which are configurable with either. Class Structure, Commands, and Examples - 178 Professional Access Point Administrator Guide Feature or Setting Configurable from CLI Configurable from Web User Interface yes Basic Settings · Getting/changing Administrator Password · Getting/changing access point name and location · Viewing information like MAC, IP address, and Firmware version Access Point and Cluster Settings yes Get existing settings only. You cannot set configuration policy or other cluster features from the CLI. Use for clustering settings. yes User Accounts User Database Backup and Restore yes You cannot backup or restore a user database from the CLI. To restore a user database, use the Web User Interface as described in "Backing Up and Restoring a User Database" on page 56. yes yes Sessions The CLI does not provide session monitoring information. To view client sessions, use the Web User Interface. yes Channel Management You cannot configure Channel Management from the CLI. To configure channel management, use the Web User Interface as described in "Channel Management" on page 63. yes Wireless Neighborhood You cannot view the cluster-based "Wireless Neighborhood" from the CLI. [. . . ] It can also be connected through leased lines or satellites. The Internet is essentially a very large WAN. WDS A Wireless Distribution System (WDS) allows the creation of a completely wireless infrastructure. Typically, an Access Point is connected to a wired LAN. WDS allows access points to be connected wirelessly. [. . . ]
