Audience

This guide is for the networking professional who installs and manages Cisco Aironet Access Points. To use this guide, you should have experience working with the Cisco IOS and be familiar with the concepts and terminology of wireless local area networks.

Purpose

This guide provides the information you need to install and configure your access point. This guide provides procedures for using the IOS commands that have been created or changed for use with the access point. It does not provide detailed information about these commands. For detailed information about these commands, refer to the Cisco Aironet Command Reference for Access Points Running Cisco IOS for this release. For information about the standard IOS Release 12.2 commands, refer to the IOS documentation set available from the Cisco.com home page at Service and Support > TechnicalDocuments. On the Cisco Product Documentation home page, select Release 12.2 from the Cisco IOS Software drop-down list.

This guide also includes an overview of the access point web-based interface (APWI), which contains all the funtionality of the command-line interface (CLI). This guide does not provide field-level descriptions of the APWI windows nor does it provide the procedures for configuring the access point from from the APWI. For all APWI window descriptions and procedures, refer to the access point online help, which is available from the Help buttons on the APWI pages.

Organization

This guide is organized into these chapters:

"Overview," lists the software and hardware features of the access point and describes the access point's role in your network.

"Configuring the Access Point for the First Time," describes how to configure basic settings on a new access point.

"Using the Web-Browser Interface," describes how to use the web-browser interface to configure the access point.

"Using the Command-Line Interface," describes how to use the command-line interface (CLI) to configure the access point.

"Administering the Access Point," describes how to perform one-time operations to administer your access point, such as preventing unauthorized access to the access point, setting the system date and time, and setting the system name and prompt.

"Configuring Radio Settings," describes how to configure settings for the access point radio such as the role in the radio network, data rates, transmit power, channel settings, and others.

"Configuring Multiple SSIDs," describes how to configure and manage multiple service set identifiers (SSIDs) on your access point. You can configure up to 16 SSIDs on your access point and assign different configuration settings to each SSID.

"Configuring an Access Point as a Local Authenticator," describes how to configure the access point to act as a local RADIUS server for your wireless LAN. If the WAN connection to your main RADIUS server fails, the access point acts as a backup server to authenticate wireless devices.

"Configuring Cipher Suites and WEP," describes how to configure the cipher suites required to use authenticated key management, Wired Equivalent Privacy (WEP), and WEP features including MIC, CMIC, TKIP, CKIP, and broadcast key rotation.

"Configuring Authentication Types," describes how to configure authentication types on the access point. Client devices use these authentication methods to join your network.

"Configuring Fast Reassociation," describes how to configure the access point to allow fast reassociation of roaming client devices. Using Cisco Centralized Key Management (CCKM) and an access point configured as a subnet context manager, client devices can roam from one access point to another without causing a delay in timing-sensitive applications, such as Voice over IP.

"Configuring RADIUS and TACACS+ Servers," describes how to enable and configure the Remote Authentication Dial-In User Service (RADIUS) and Terminal Access Controller Access Control System Plus (TACACS+), which provide detailed accounting information and flexible administrative control over authentication and authorization processes.

"Configuring VLANs," describes how to configure your access point to interoperate with the VLANs set up on your wired LAN.

"Configuring QoS," describes how to configure quality of service (QoS) on your access point. With this feature, you can provide preferential treatment to certain traffic at the expense of others.

"Configuring Proxy Mobile IP," describes how to configure your access point's proxy mobile IP feature. When you enable proxy mobile IP on your access point and on your wired network, the access point helps client devices from other networks remain connected to their home networks.

"Configuring Filters," describes how to configure and manage MAC address, IP, and Ethertype filters on the access point using the web-browser interface.

"Configuring CDP," describes how to configure Cisco Discovery Protocol (CDP) on your access point. CDP is a device-discovery protocol that runs on all Cisco network equipment.

"Configuring SNMP," describes how to configure the Simple Network Management Protocol (SNMP) on your access point.

"Configuring Repeater and Standby Access Points," descibes how to configure your access point as a hot standby unit or as a repeater unit.

"Managing Firmware and Configurations," describes how to manipulate the Flash file system, how to copy configuration files, and how to archive (upload and download) software images.

"Configuring System Message Logging," describes how to configure system message logging on your access point.

"Troubleshooting," provides troubleshooting procedures for basic problems with the access point.

"Channels and Antenna Settings," lists the access point radio channels and the maximum power levels supported by the world's regulatory domains.

"Protocol Filters," lists some of the protocols that you can filter on the access point.

"Supported MIBs," lists the Simple Network Management Protocol (SNMP) Management Information Bases (MIBs) that the access point supports for this software release.

"Error and Event Messages," lists the CLI error and event messages and provides an explanation and recommended action for each message.

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The avenue of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.

We categorize Cisco TAC inquiries according to urgency:

•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

Cisco TAC Website

You can use the Cisco TAC website to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC website, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website require a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:
