Before using this guide,you should have experience working with Cisco IOS commands and access point and bridge softwarefeatures.You also need to be familiar with the concepts and terminology of Ethernet and local areanetworking.PurposeThis guide provides information about new and revised Cisco IOS commands. For information about thestandard Cisco IOS commands, refer to the IOS documentation set available from the Cisco.com home tsd products support series home.htmlThis guide does not provide procedures for configuring your access point or bridge. For detailedconfiguration procedures, refer to the Cisco IOS Software Configuration Guide for Cisco Aironet AccessPoints, the Cisco Aironet 1300 Series Outdoor Access Point/Bridge Software Configuration Guide, orthe Cisco Aironet 1400 Series Bridge Software Configuration Guide for this release.OrganizationThis guide is organized into these sections:Chapter 1, “Using the Command-Line Interface,” describes how to access the command modes and usethe command-line interface (CLI) to configure software features.Chapter 2, “Cisco IOS Commands for Access Points and Bridges,” describes in alphabetical order theCisco IOS commands that you use to configure and monitor your access point or bridge.Appendix A, “List of Supported Cisco IOS Commands,” lists the Cisco IOS commands that accesspoints and bridges support. Cisco IOS commands that are not in this list have not been tested on accesspoints and bridges and might not be supported.Cisco IOS Command Reference for Cisco Aironet Access Points and Bridges0L-24115-01v

C H A P T E R1Using the Command-Line InterfaceThis chapter describes how to use the Cisco IOS command-line interface (CLI) for configuring softwarefeatures on your access point or bridge.For a complete description of the new and revised Cisco IOS commands supported by access points andbridges, see Appendix A, “List of Supported Cisco IOS Commands.”For more information on Cisco IOS commands, refer to the Cisco IOS Release 12.3 Command Summary.For task-oriented configuration steps, refer to the Cisco IOS Software Configuration Guide for CiscoAironet Access Points or the Cisco Aironet 1400 Series Wireless Bridge Software Configuration Guide.Type of MemoryThe access point and bridge Flash memory stores the Cisco IOS software image, the startupconfiguration file, and helper files.CLI Command ModesThis section describes the CLI command mode structure. Command modes support specific Cisco IOScommands. For example, the interface interface-id command works only when entered in globalconfiguration mode.These are the main command modes for access points and bridges: User EXEC Privileged EXEC Global configuration Interface configurationTable 1-1 lists the main command modes, how to access each mode, the prompt you see in that mode,and how to exit that mode. The prompts listed use the default name ap.Cisco IOS Command Reference for Cisco Aironet Access Points and Bridges0L-24115-011-1
Chapter 1Using the Command-Line InterfaceCLI Command ModesTable 1-1Command Modes SummaryCommand ModeAccess MethodPromptExitUser EXECThis is the first level of access.AP Enter the logout command.Change terminal settings,perform basic tasks, and listsystem information.Privileged EXECFrom user EXEC mode, enter the AP#enable command.To exit to user EXEC mode, enter thedisable command.GlobalconfigurationFrom privileged EXEC mode,enter the configure command.To exit to privileged EXEC mode,enter the exit or end command, orpress Ctrl-Z.InterfaceconfigurationFrom global configuration mode, AP(config-if)#specify terminal then specify aninterface by entering theinterface command followed bythe interface type and number.AP(config)#To exit to privileged EXEC mode,enter the end command, or pressCtrl-Z.To exit to global configuration mode,enter the exit command.User EXEC ModeAfter you access the device, you are automatically in user EXEC command mode. The EXEC commandsavailable at the user level are a subset of those available at the privileged level. In general, use the EXECcommands to temporarily change terminal settings, perform basic tests, and list system information.The supported commands can vary depending on the version of Cisco IOS software in use. To view acomprehensive list of commands, enter a question mark (?) at the prompt.AP ?Privileged EXEC ModeBecause many of the privileged commands configure operating parameters, privileged access should bepassword-protected to prevent unauthorized use. The privileged command set includes those commandscontained in user EXEC mode, as well as the configure privileged EXEC command through which youaccess the remaining command modes.If your system administrator has set a password, you are prompted to enter it before being granted accessto privileged EXEC mode. The password does not appear on the screen and is case sensitive.The privileged EXEC mode prompt is the device name followed by the pound sign (#):AP#Enter the enable command to access privileged EXEC mode:AP enableAP#Cisco IOS Command Reference for Cisco Aironet Access Points and Bridges1-20L-24115-01
Chapter 1Using the Command-Line InterfaceCLI Command ModesThe supported commands can vary depending on the version of Cisco IOS software in use. To view acomprehensive list of commands, enter a question mark (?) at the prompt.AP# ?To return to user EXEC mode, enter the disable privileged EXEC command.Global Configuration ModeGlobal configuration commands apply to features that affect the device as a whole. Use the configureprivileged EXEC command to enter global configuration mode. The default is to enter commands fromthe management console.When you enter the configure command, a message prompts you for the source of the configurationcommands:AP# configureConfiguring from terminal, memory, or network [terminal]?You can specify the terminal or memory as the source of configuration commands.This example shows you how to access global configuration mode:AP# configure terminalEnter configuration commands, one per line. End with CNTL/Z.AP(config)#The supported commands can vary depending on the version of Cisco IOS software in use. To view acomprehensive list of commands, enter a question mark (?) at the prompt:AP(config)# ?To exit global configuration command mode and to return to privileged EXEC mode, enter the end orexit command, or press Ctrl-Z.Interface Configuration ModeInterface configuration commands modify the operation of the interface. Interface configurationcommands always follow a global configuration command, which defines the interface type.Use the interface interface-id command to access interface configuration mode. The new prompt meansinterface configuration mode:AP(config-if)#The supported commands can vary depending on the version of Cisco IOS software in use. To view acomprehensive list of commands, enter a question mark (?) at the prompt:AP(config-if)# ?To exit interface configuration mode and to return to global configuration mode, enter the exitcommand. To exit interface configuration mode and to return to privileged EXEC mode, enter the endcommand, or press Ctrl-Z.Cisco IOS Command Reference for Cisco Aironet Access Points and Bridges0L-24115-011-3
