Release Notes for Cisco Aironet Configuration Administration Tool (ACAT) 1.2
These release notes describe features and caveats for the Cisco Aironet Configuration Administration Tool (ACAT) version 1.2.
ACAT is a tool used by administrators to specify software installation options for client adapters located in PCs running a Windows operating system. The specified options are placed in a configuration file used by the Cisco Aironet Wireless LAN Client Adapter Installation Wizard (Install Wizard) to install the software components and a client adapter's configuration profiles. ACAT supports the Windows 98, ME, NT, 2000, and XP operating systems.
Using ACAT, an administrator can specify the following installation options:
–Client adapter radio firmware
–Driver for a client adapter
–Cisco Aironet Client Utility (ACU)
–Cisco Aironet Client Monitor (ACM)
–Security Modules (LEAP, EAP-SIM, and PEAP)
•Administrator global over-ride settings
•Client adapter configuration profiles
•Client adapter type
–PCMCIA4800—Aironet 4800 series PCMCIA card
–PCI4800—Aironet 4800 series PCI card
–ISA4800—Aironet 4800 series ISA card
–PCM-34x—Cisco Aironet 340 series PCMCIA card
–PCI-34x—Cisco Aironet 340 series PCI client adapter
–PCM-35x—Cisco Aironet 350 series PCMCIA card
–MPI-35x—Cisco Aironet 350 series Mini-PCI card
–PCI-35x—Cisco Aironet 350 series PCI card
–CB20A—Cisco Aironet 5-GHz PC-Cardbus card
Note An LMC-340 or LMC-350 card must be configured as a PCM adapter type (PCM-34x or PCM-35x).
WPA Migration Mode Not Supported by Clients
Although the software components included in client adapter Install Wizard version 1.2 support Wi-Fi Protected Access (WPA) authenticated key management for 350 series and CB20A cards on computers running Windows 2000 or XP (see the "WPA Support" section for more information), they do not include support for WPA migration mode.
In order to use Cisco Aironet client adapters with WPA, the access point must be configured only for the WPA TKIP cipher. The use of the following migration-mode-supporting ciphers is not supported by Cisco WPA clients:
•TKIP + WEP128
•TKIP + WEP40
To support the coexistence of Cisco Aironet WPA clients and non-WPA clients, it is necessary to configure separate VLANs and encryption policies. Specifically, a VLAN with TKIP encryption mode and a VLAN with a compatible WEP encryption mode specified would be required. For additional information refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points.
Cisco Aironet Software Requires Completion of Encryption Authorization Form
In order to access Cisco Aironet software from the Software Center on Cisco.com, you must now fill out a form to receive authorization to download encrypted software. Registered Cisco.com users are required to fill out the form only once, while public users must do so once each session, each time software is downloaded.

Silent Setup Options
Three new options are available when Silent Setup is selected on the Global Override screen:
•Prompt for reboot— the installation process displays a message indicating a reboot is necessary and asks if you wants to reboot now.
•Reboot silently—the installation process automatically reboots the PC.
•Do not reboot—the installation process does not display a prompt message and waits for you to reboot the PC.
Note For PCs running the Windows 98 operating system, the installation process automatically reboots
Wi-Fi Protected Access (WPA) is a standards-based, interoperable security enhancement that strongly increases the level of data protection and access control for existing and future wireless LAN systems. It is derived from and will be compatible with the upcoming IEEE 802.11i standard. WPA leverages Temporal Key Integrity Protocol (TKIP) and Michael message integrity check (MIC) for data protection and 802.1X for authenticated key management.
WPA supports two mutually exclusive key management types: WPA and WPA-Pre-shared key (WPA-PSK). Using WPA key management, clients and the authentication server authenticate to each other using an EAP authentication method, and the client and server generate a pairwise master key (PMK). The server generates the PMK dynamically and passes it to the access point. Using WPA-PSK key management, however, you configure a pre-shared key on both the client and the access point, and that pre-shared key is used as the PMK.
Only 350 series and CB20A cards that are installed on computers running Windows 2000 or XP and running LEAP or host-based EAP authentication can be used with WPA. Support for WPA is available in the software components included in Install Wizard version 1.2 or greater. However, if you want to use host-based EAP authentication with WPA, you must also install a host supplicant with WPA support. The following host supplicants are recommended for use with Cisco Aironet client adapters:
•Funk Odyssey Client supplicant version 2.2 (for Windows 2000)
•Windows XP Service Pack 1 and Microsoft supplicant Q815485 (for Windows XP)
Note Refer to the 340, 350, and CB20A Wireless LAN Client Adapters Installation and Configuration Guide for Windows (version OL-1394-07) for instructions on enabling WPA on your client adapter.
WPA must also be enabled on the access point. Access points must use Cisco IOS Release 12.2(11)JA or greater to enable WPA. Refer to the documentation for your access point for instructions on enabling this feature.
Fast Roaming (CCKM)
Some applications that run on a client device may require fast roaming between access points. Voice applications, for example, require seamless roaming to prevent delays and gaps in conversation. Support for fast roaming is available for LEAP-enabled clients in Install Wizard version 1.1 or later.
During normal operation, LEAP-enabled clients mutually authenticate with a new access point by performing a complete LEAP authentication, including communication with the main RADIUS server. However, when you configure your wireless LAN for fast roaming, LEAP-enabled clients securely roam from one access point to another without the need to reauthenticate with the RADIUS server. Using Cisco Centralized Key Management (CCKM), an access point that is configured for wireless domain services (WDS) uses a fast rekeying technique that enables client devices to roam from one access point to another in under 150 milliseconds (ms). Fast roaming ensures that there is no perceptible delay in time-sensitive applications such as wireless Voice over IP (VoIP), enterprise resource planning (ERP), or Citrix-based solutions.
This feature is enabled on the client adapter in two different ways, depending on the software installed:
•If you are using client adapter firmware version 5.30.xx (which is included in Install Wizard version 1.2), you need to enable fast roaming in ACAT or the Aironet Client Utility (ACU) version 6.2.
•If you are using client adapter firmware version 5.20.17 (which is included in Install Wizard version 1.1), fast roaming is supported automatically.
Regardless of how fast roaming is enabled on the client adapter, it must also be enabled on the access point.
Note Access points must use Cisco IOS Release 12.2(11)JA or greater to enable fast roaming. Refer to the documentation for your access point for instructions on enabling this feature.
Note If the Microsoft 802.1X supplicant is installed on your computer, you must disable one or two Windows parameters in order for this feature to operate correctly.
Scan For a Better Access Point
Selecting this feature causes the client adapter to look for a better access point if the signal strength of its associated access point is less than the specified value after the specified time and to switch associations if it finds one.
Example: If the default values of 20 seconds and 50% are used, the client adapter begins monitoring the strength of the signal received from its associated access point 20 seconds after becoming associated. The monitoring continues once per second. If the client detects a signal strength reading below 50%, it scans for a better access point.
Getting Bug Information on Cisco.com
If you are a registered Cisco user, you can use the Cisco TAC Software Bug Toolkit, which consists of three tools (Bug Navigator, Bug Watcher, and Search by Bug ID Number) that help you identify existing bugs (or caveats) in Cisco software products.
Access the TAC Software Bug Toolkit at the following URL:
The following caveats have not been resolve:
•CSCin53301—Some contents are partially seen on the RF Settings and Security pages.
The Defaults button does not uncheck the Allow association to both WPA and non-WPA Authentications option.
Workaround: Uncheck the Allow association to both WPA and non-WPA Authentications option.
•CSCin58186—ACAT reboot silently installation option.
The Reboot Silently option in the Silent Setup menu on the Global Override Settings tab requires user intervention to respond to a reboot message.
Workaround: You must click Yes on the message asking if you want to reboot now.
•CSCin58727—Settings in ACAT and ACU are not the same.
When configuring LEAP, ACAT allows LEAP Authentication Timeout values between 45 and 300 seconds. The Aironet Client Utility (ACU) allows LEAP Authentication Timeout values between 10 and 300 seconds.
Workaround: To set a LEAP Authentication Timeout value of less than 45 seconds, you must use the ACU after the installation completes.
The following caveat has been resolved:
•CSCea38113—Non-writable destination drive causes Install Wizard to fail
If you designate a non-writable drive (such as your computer's CD-ROM drive) as the destination folder for the ACU, the Install Wizard stops and does not complete. No error message or warning is displayed.
This problem has been resolved.
