B CLI for AP Configuration Table 33. Interface Naming Convention Interface wlan0bssvapx wlan1bssvapx Description The basic service set interface for the x VAP on radio 1 - 802.11a radio. The value for x ranges from 0-7. The DWL-3500AP does not have this interface. The basic service set interface for the x VAP on radio 2 - 802.11b/g radio. The value for x ranges from 0-7. NOTE: The commands and examples in this appendix use radio 1. To configure and view information about the second radio, replace the "wlan0" portion of the interface name with wlan1. Use the command get radio all to view information about the radios on the Unified Access Point. Saving Configuration Changes The Unified Access Point maintains three different configurations. • Factory Default Configuration - This configuration consists of the default settings shipped with the access point (as specified in "Default Settings for the Unified Access Points" on page 19). You can always return the AP to the factory defaults by using the factory-reset command. • Startup Configuration - The startup configuration contains the settings with which the AP will use the next time it starts up (for example, upon reboot). To save configuration updates made from the CLI to the startup configuration, you must execute the save-running or set config startup running command from the CLI after making changes. • Running Configuration - The running configuration contains the settings with which the AP is currently running. When you view or update configuration settings through the command line interface (CLI) using get, set, add, and remove commands, you are viewing and changing values on the running configuration only. If you do not save the configuration (by executing the saverunning or "set config startup running" command at the CLI), you will lose any changes you submitted via the CLI upon reboot. The save-running command saves the running configuration as the startup configuration. (The save-running command is a shortcut command for set config startup running, which accomplishes the same thing) Settings updated from the CLI (with get, set, add, remove commands) will not be saved to the startup configuration unless you explicitly save them via the save-running command. This gives you the option of maintaining the startup configuration and trying out values on the running configuration that you can discard (by not saving). By contrast, configuration changes updated from the Web UI are automatically saved to both the running and startup configurations. If you make changes from the Web UI that you do not want to keep, your only option is to reset to factory defaults. The previous startup configuration will be lost. Saving Configuration Changes 133

CLI for AP Configuration

NOTE:

The commands and examples in this appendix use radio 1. To configure and

view information about the second radio, replace the “wlan0” portion of the

interface name with wlan1. Use the command

get radio all

to view

information about the radios on the Unified Access Point.

Saving Configuration Changes

The Unified Access Point maintains three different configurations.

•

Factory Default Configuration

- This configuration consists of the default settings

shipped with the access point (as specified in

“Default Settings for the Unified Access

Points”

on page 19).

You can always return the AP to the factory defaults by using the

factory-reset

command.

•

Startup Configuration

- The startup configuration contains the settings with which the

AP will use the next time it starts up (for example, upon reboot).

To save configuration updates made from the CLI to the

startup

configuration, you must

execute the

save-running

set config startup running

command from the CLI

after making changes.

•

Running Configuration

- The running configuration contains the settings with which the

AP is currently running.

When you view or update configuration settings through the command line interface (CLI)

using

get

set

add

, and

remove

commands, you are viewing and changing values on the

running

configuration only. If you do not save the configuration (by executing the

save-

running

or “

set config startup running

” command at the CLI), you will lose any

changes you submitted via the CLI upon reboot.

The

save-running

command saves the

running

configuration as the startup configuration.

(The

save-running

command is a shortcut command for

set config startup running

which accomplishes the same thing)

Settings updated from the CLI (with

get

set

add

remove

commands) will not be saved to

the startup configuration unless you explicitly save them via the

save-running

command.

This gives you the option of maintaining the

startup

configuration and trying out values on the

running

configuration that you can discard (by not saving).

By contrast, configuration changes updated from the Web UI are automatically saved to both

the

running

and

startup

configurations. If you make changes from the Web UI that you do not

want to keep, your only option is to reset to factory defaults. The previous startup

configuration will be lost.
