Release Notes for Cisco Aironet 802.11a/b/g (CB21AG and PI21AG) Client Administration Utility (ACAU) Version 2.0
May 3, 2005
These release notes describe caveats for the Aironet Client Adapters Administration Utility (ACAU)
ACAU is a utility used by administrators to configure administrative overrides and create profiles for users who install CB21AG and PI21AG wireless client adapters in PCs running Windows 2000 or Windows XP operating systems. The overrides and profiles are stored in configuration files that are loaded into the Aironet Desktop Utility (ADU) Install Wizard. After a user installs the drivers and ADU for their client adapter, the Install Wizard uses the instructions in the configuration file to preconfigure ADU user settings and load one or more user profiles.
Using ACAU, an administrator can perform the following operations:
•Determine and configure the setup options for the ADU software
•Set ADU user functions
•Create preconfigured user profiles for a user or group of users
Generally, the system requirements for ACAU are the same as the client adapter:
•A computer running the Windows 2000 or XP operating system
Note Cisco recommends a 300-MHz (or greater) processor.
•Service Pack 2 for Windows XP
•20 MB of free hard disk space (minimum)
•128 MB of RAM or greater (recommended)
•If the wireless network uses EAP-TLS or PEAP authentication, the following must be on the user's PC:
–Certificate of Authority (CA) and user certificates for EAP-TLS authentication or CA certificate for PEAP authentication
•If the wireless network uses PEAP (EAP-GTC) authentication with a One-Time Password (OTP) user database, the following must be on the user's PC:
–A hardware token device from OTP vendors or Secure Computing SoftToken program (release 2.1 or later)
–Your hardware or software token password
•The Microsoft 802.1X supplicant, if your client adapter is installed on a Windows 2000 device and uses PEAP (EAP-MSCHAPV2) with machine authentication.
•All necessary devices (such as access points, servers, gateways, user databases, etc.) must be properly configured for any authentication type you plan to enable on a client.
The following new features have been incorporated in version 2.0:
•Support for EAP-FAST Authentication
•Support for Domain Logon with EAP-TLS
•Support for WiFi Protected Access 2 (WPA2)
•CCKM Fast Secure Roaming Supported with All EAP Types
•Support for Wi-Fi Multimedia
New Site Survey Utility
A site survey utility is now available for the CB21AG and PI21AG client adapters. The utility, which is designed to be used by people responsible for conducting a site survey, is useful in determining the best placement of infrastructure devices within a wireless network. The utility is a stand-alone application, separate from ADU, that runs from an executable file. If you check the Install Cisco Aironet Site Survey Utility check box during installation of Install Wizard 2.0, the site survey executable file is installed in the C:\Program Files\Cisco Aironet directory (unless you specify a different directory).
During a site survey, the current status of the network is read from the client adapter, and the status display is updated four times per second so you can accurately gauge network performance. The feedback that you receive can help you to eliminate areas of low RF signal levels that can result in a loss of connection between the client adapter and its associated access point (or other infrastructure device).
To open the site survey utility, choose Start > Programs > Cisco Aironet > Aironet Site Survey Utility. (If you specify a different program folder during installation, you must access the site survey utility from that folder.)
Note The site survey utility is supported for use with only CB21AG and PI21AG client adapters.
Note Refer to Appendix F of the Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration Guide (part number OL-4211-03) for more information on the site survey utility.

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
