Introduction

This document describes system requirements, important notes, new and changed information, installation and upgrade procedures, and caveats for Cisco Aironet Client Administration Utility (ACAU) version 3.0.

ACAU is a utility used by administrators to set software installation options and create profiles (saved configurations) for users who install Cisco Aironet CB21AG and PI21AG Wireless LAN Client Adapters in computers running the Windows 2000 or Windows XP operating system. Administrators save the installation settings and profiles to a configuration file. Then when the user installs the client adapter software (driver and client utilities), the Install Wizard uses the instructions in the configuration file to govern the installation and setup of the client utilities and load one or more preconfigured user profiles. Administrators can create configuration files to control the installation and configuration of client adapters for one user or groups of users.


Note To ensure proper operation, use ACAU 3.0 only with client adapter Install Wizard 3.0.


System Requirements

You need the following items in order to install and use ACAU 3.0:

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 (Professional, Home); Service Pack 4 for Windows 2000

20 MB of free hard disk space (minimum)

128 MB of RAM or greater (recommended)

Important Notes

Incompatibility between PACs Created by ACS Version 3.x.xx and ACS Version 4.0.xx

PACs that are created by ACS version 3.x.xx are not compatible with ACS version 4.0.xx. Client stations must import new PACs. If you select auto-provisioning, new PACs will automatically be generated and used. However, if you select manual provisioning, you must manually export new PACs to the client stations.

If a user wants to authenticate to ACS version 4.0.xx and version 3.x.xx at different times, both PACs must remain on the client station. The ADU is capable of automatically selecting the appropriate PAC.

However, if you experiences authentication failures after upgrading the software, delete all the PACs provisioned from the 3.x.xx server.

Conflict with Third-Party Supplicants

When using release 3.0, you might encounter a conflict with third-party supplicants (such as the Meetinghouse Aegis or the Juniper Odyssey) that causes the Cisco client adapter to lose connection. If you encounter such a conflict, disable third-party supplicants.

Software Compatibility

ACAU 3.0 is compatible with only the Cisco Aironet CB21AG and PI21AG client adapters.

Name and Location of Configuration File

You can change the name of the ACAU configuration file; however, the name must be changed back to CiscoAdminConfig.dat before the user runs the Install Wizard. Otherwise, the Install Wizard does not load the configuration file.

You must also save the configuration file to the drive and directory in which the Install Wizard resides. If you save the file to any other location, it is not processed by the Install Wizard.

Installing the Novell Client

To ensure proper operation, the Novell Client (if used) must be installed on the user's computer prior to the client adapter software.

Host Based EAP Profiles Created with Earlier ACAU Versions

If you created a Host Based EAP profile using ACAU 1.2 or 1.3 and import it for use with ACAU 2.5, it is designated as an EAP-FAST profile in ACAU 2.5. To change it, you must manually reconfigure the profile for Host Based EAP.

New and Changed Information

This section describes the new and modified features in version 3.0 of ACAU.

EAP-FAST Enhancements

The following is a list of EAP-FAST enhancements, which are accessible through the ACAU user interface:

Support of additional EAP authentication methods

Version 3.0 of ACAU supports three EAP methods in both the PAC auto provisioning phase and the EAP-FAST authentication phase. These methods are:

EAP-MSCHAPv2

EAP-GTC

EAP-TLS

PAC configuration and management screens

Version 3.0 of ACAU has updated PAC configuration screens.

For more information about the new updates, refer to the Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Administration Utility Administrator Guide (OL-7086-03).

PAC Export

In the previous version, when an EAP-FAST profile is exported or imported, the PAC data linked with the profile was getting ignored. To solve this problem, version 3.0 of ACAU supports the exporting of PAC data using .PAC files.

Caveats

This section lists open and resolved software issues in ACAU 3.0.

Open Caveats

The following caveats are not resolved in ACAU 3.0:

CSCsb74191—The error message displayed when using the 5GHz Ad Hoc mode in a European-country domain is not clear

If, when creating a new profile for an Ad Hoc network, you select 5GHz 54Mbps from the Wireless Mode pop-up menu, the following error message might appear:

"An Ad Hoc Wireless mode must be selected for starting Ad Hoc network."

This error message is displayed if the user does not select the correct wireless mode. However, this message is also displayed if the current wireless regulatory domain, country setting, or the card SKU do not allow creation of an Ad Hoc network in that wireless mode.

When creating a new profile, the ADU software does not take into account the SKU of the client adapter inserted into the computer or the current country code and regulatory domain. By not recording the SKU, the country code, and the regulatory domain, the profiles can be easily exported and imported into other computers that use different client adapters and country codes.

One side-effect of making profiles easy to import to other systems is that the client software's underlying driver will dynamically apply the appropriate limitations based on the current network settings while activating a profile. However, these limitations will be visible only in the Diagnostics and Advanced Status pages, but not under Profile Management.

CSCsd80097—The CB21AG client adapter with versions 2.6 or 3.0 drivers installed on a Compaq NX 6110 computer exhibits roaming inconsistencies with the G channels. This issue has not been verified by Cisco.

The reason for the flakiness is that the cardbus controller driver was not getting installed and the generic driver was used instead. To fix the problem, download the sp30219.exe file from the HP support website onto your system and run it to install the media card reader driver to fix the roaming inconsistencies.

CSCsd02837—The CB21AG client adapter does no send re-association requests in mobility

The CB21AG client adapter does no send re-association requests with the CCKM keys when moved from controller to another. The adapter sends re-association request with CCKM keys only when it roams back to the controller to which it was first attached. This issue occurs when the access point is configured to use WPA2 for key management.

This issue can be solved by using WPA key management with TKIP and CCKM.

Resolved Caveats

The following caveat has been resolved in ACAU 3.0.

CSCei67249—WEP key setting in ACAU profile fails to transfer to ADU profile

If you create a profile with a 128-bit static WEP key and choose the Install & Run option under Global Settings > Setup Settings > Profile Migration Tool in ACAU and save these settings to the CiscoAdminConfig.dat file, this profile is no longer configured for 128-bit static WEP after it is loaded into ADU.
