Release Notes for Cisco Aironet 802.11a/b/g (CB21AG and PI21AG) Client Administration Utility (ACAU) 1.1
This document describes system requirements, important notes, installation and upgrade procedures, and caveats for CB21AG and PI21AG client adapter ACAU release 1.1.
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 the Windows 2000 or Windows XP operating system. The overrides and profiles are stored in a configuration file that is loaded by the Install Wizard. After the user installs the driver and Aironet Desktop Utility (ADU) for the 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 for the client adapter:
•A computer running the Windows 2000 or XP operating system
Note Cisco recommends a 300-MHz (or greater) processor.
•Service Pack 1 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 SofToken program (release 2.1 or later)
Administrators can always modify, create, remove, import, and export profiles, even if ACAU's global user settings are set to prevent users from performing these functions.
Compatibility with Client Adapters
ACAU is compatible with the Cisco Aironet CB21AG and PI21AG client adapters. The ACAU software is incompatible with other Cisco Aironet client adapter software.
The Aironet Desktop Utility (ADU) must be used with CB21AG and PI21AG client adapters, and the Aironet Client Utility (ACU) must be used with all other Cisco Aironet client adapters.

This section describes open and resolved caveats for ACAU 1.1.
The following caveat is not resolved in ACAU 1.1.
•CSCee81762—ACAU-created profiles not reflected in ADU
ACAU-created profiles do not appear in ADU following a software upgrade. To work around this problem, uninstall the previous installation and then perform a fresh install. The ACAU-created profiles should now appear in ADU.
The following caveats are resolved in ACAU 1.1.
•CSCed01662—Profile created in ACAU does not append to existing profile in ciscoadminconfig.dat file
The problem occurs when an ACAU-generated configuration file is used to install the driver and ADU on a client's system after a user has created profiles using ADU. When the user reinstalls the driver and ADU using the modified configuration file and selecting the Update the previous installation option, the profile generated by the ACAU profile does not appear in ADU's profile list. To work around this problem, select the Uninstall the previous installation option and reinstall the driver and ADU.
•CSCec87582—Reboot at end of silent install should be configurable
ACAU 1.0 does not provide an option to not reboot when a silent installation is selected in the Global Settings section. ACAU 1.1 provides three reboot options for a silent installation:
–Prompt for reboot
–Reboot without prompting
–Do not reboot

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.
