Cisco Aironet 1100 Series Access Point Installation and Configuration Guide
OL-2851-01
Preface
Audience
This guide is for the networking professional who installs and manages the Cisco Aironet 1100 Series
Access Point, hereafter referred to as the access point. 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 1100 Series Access Point Command Reference 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:
Chapter 1, “Overview,”lists the software and hardware features of the access point and describes the
access point’s role in your network.
Chapter 2, “Installing the Access Point,”describes installing your access point on a desktop, wall, or
ceiling, and provides safety warnings and general guidelines.
Chapter 3, “Configuring the Access Point for the First Time,”describes how to configure basic settings
on a new access point.

Preface
Organization
Chapter 4, “Using the Web-Browser Interface,”describes how to use the web-browser interface to
configure the access point.
Chapter 5, “Using the Command-Line Interface,”describes how to use the command-line interface
(CLI) to configure the access point.
Chapter 6, “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.
Chapter 7, “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.
Chapter 8, “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.
Chapter 9, “Configuring WEP and WEP Features,”describes how to configure Wired Equivalent Privacy
(WEP), Message Integrity Check (MIC), Temporal Key Integrity Protocol (TKIP), and broadcast key
rotation to protect your wireless LAN.
Chapter 10, “Configuring Authentication Types,”describes how to configure authentication types on the
access point. Client devices use these authentication methods to join your network.
Chapter 11, “Configuring RADIUS Servers,”describes how to enable and configure the Remote
Authentication Dial-In User Service (RADIUS), which provides detailed accounting information and
flexible administrative control over authentication and authorization processes.
Chapter 12, “Configuring VLANs,”describes how to configure your access point to interoperate with
the VLANs set up on your wired LAN.
Chapter 13, “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.
Chapter 14, “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.
Chapter 15, “Configuring Filters,”describes how to configure and manage MAC address, IP, and
Ethertype filters on the access point using the web-browser interface.
Chapter 16, “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.
Chapter 17, “Configuring SNMP,”describes how to configure the Simple Network Management
Protocol (SNMP) on your access point.
Chapter 18, “Configuring Repeater and Standby Access Points,”descibes how to configure your access
point as a hot standby unit or as a repeater unit.
Chapter 19, “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.
Chapter 20, “Configuring System Message Logging,”describes how to configure system message
logging on your access point.
Chapter 21, “Troubleshooting,”provides troubleshooting procedures for basic problems with the access
point.
Appendix A, “Translated Safety Warnings,”provides translations of the safety warnings that appear in
this publication.
Appendix B, “Declarations of Conformity and Regulatory Information,”provides declarations of
conformity and regulatory information for the access point.
