Release Notes for Cisco Aironet 802.11a/b/g (CB21AG and PI21AG) Client Administration Utility (ACAU) 2.5
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 2.5.
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 2.5 only with client adapter Install Wizard 2.5.
You need the following items in order to install and use ACAU 2.5:
•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)
ACAU 2.5 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
New Setup Settings Parameters
These two Setup Settings parameters are now available in ACAU:
•Installation type—Specifies whether user input is required when the client adapter software is upgraded or uninstalled.
Options: Normal, Silent upgrade, or Silent uninstall
•Profile Migration Tool—Determines whether the profile migration tool is installed and run on the user's computer. The tool is designed to migrate Cisco Aironet 350 series and CB20A wireless LAN client adapter profiles to profiles that can be used with Cisco Aironet CB21AG and PI21AG client adapters.
Options: Don't Install, Install, or Install & Run
Default: Don't Install
Note See Appendix D of the Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Administration Utility Administrator Guide (OL-7086-02) for the list of available command line options and more information on the profile migration tool.
Ability to Lock Profiles
As an added security measure, ACAU gives you the option of locking individual profiles, which prevents users from being able to modify or remove these profiles. To lock a profile, simply check the Locked Profile check box on the Profile Editor (Security) window.
This feature ensures a high level of security and consistent configurations. It is especially useful if you want to create a standard profile for the corporate network, distribute it to each user, and ensure that it cannot be modified or removed.
The following rules apply to locked profiles:
•Locked profiles can be created only by an administrator using ACAU.
•A profile can be individually locked or unlocked; however, a user's ability to modify profiles (through ACAU's Global Settings - User Settings parameters) takes precedence. For example, if a user is not permitted to modify a profile, he or she is also unable to modify an unlocked profile.
•A locked profile cannot be overwritten, either by import or from the conversion of a 350 or CB20A profile through the profile migration tool.
•When a locked profile is exported and then imported onto another machine, the profile remains locked.
•All fields in a locked profile are read-only except password fields, which can be edited.
Secure Session Resume
An Always Resume the Secure Session check box has been added to the LEAP Settings, EAP-FAST Settings, and Define PEAP (EAP-GTC) Configuration windows.
•Checking this check box causes the LEAP, EAP-FAST, or PEAP (EAP-GTC) supplicant to always attempt to resume the previous session without prompting the user to re-enter his or her credentials whenever the client adapter becomes disassociated. The session resumes after the client temporarily loses connection to the access point, such as by roaming in and out of range [LEAP, EAP-FAST, and PEAP (EAP-GTC)], or wakes up from suspend or hibernate mode (LEAP and EAP-FAST). This is the default setting.
•Unchecking this check box causes the user to be prompted to re-enter his or her LEAP, EAP-FAST, or PEAP (EAP-GTC) username and password whenever the client adapter temporarily loses association by roaming out of range [LEAP, EAP-FAST, and PEAP (EAP-GTC)] or wakes up from suspend or hibernate mode (LEAP and EAP-FAST).
Note This check box is available for LEAP and EAP-FAST only if you selected the Automatically Prompt for User Name and Password or Manually Prompt for User Name and Password option. It is available for PEAP (EAP-GTC) only if you selected the Token option.
Enhanced Site Survey Utility
The site survey utility, which is useful in determining the best placement of infrastructure devices within a wireless network, has been modified to include the following enhancements:
•Fit Columns button—This button enables you to resize the columns on the AP scan list so that you can view the text in each column without it being truncated.
•Time of Day field—This field in the AP scan list shows the date and time when the signal strength of each access point was at its maximum.
•Other Information field—This field in the AP scan list contains some new values, such as WMM, WPA, and WPA2.
•Enable Expert Mode for AP Detailed Information parameter—This check box on the Options window causes the AP Detailed Information window to display debugging information, including a hexadecimal debug-style dump of raw access point scan data, under the "Expert Mode (Debug Dump" heading.
•Accumulate button—This button changes the behavior of the AP scan list. Instead of displaying only the current AP scan list, the list includes all of the access points (based on MAC address) that have appeared in the scan list since the Accumulate button was last clicked. After a scan line is added to the list, it is never removed nor updated with new scan information unless the signal strength (RSSI) of the latest scan is greater than or equal to any seen previously from that access point.
•Proximity beeper—This beeper can be used to identify areas where wireless coverage is good or weak based on the client adapter's proximity to access points within a particular area. The beeper can be set to sound as the client adapter approaches or moves farther away from an access point.
•Thresholds—You can now perform the following threshold-related tasks:
–Configure threshold values that trigger audible alerts, entries in the threshold log file, or both
–Enable audible threshold alerts and the logging of text messages to the threshold log file when a threshold condition occurs
–Enter a comment in the threshold log file
–View or delete the threshold log file
•AP scanning—You can now perform the following tasks related to AP scanning:
–Configure the site survey utility to automatically copy the contents of the AP scan list to a log file
–Enable AP scan logging
–View or delete the AP scan log
–Save or open the AP scan list
•Status bar indicators—Four indicators on the site survey utility's status bar indicate when certain features are enabled:
–PRX—The proximity beeper is enabled.
–ALR—Threshold alerts are enabled.
–LOG—Threshold logging is enabled.
–APS—Automatic AP scan list logging is enabled.
The site survey 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 2.5, the site survey executable file is installed in the C:\Program Files\Cisco Aironet directory (unless you specify a different directory).
Note The site survey utility can be used only with 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 (OL-4211-04) for more information on the site survey utility.
Profile Migration Tool
A profile migration tool is now available for the CB21AG and PI21AG client adapters. This tool is designed to migrate Cisco Aironet 350 series and CB20A wireless LAN client adapter profiles to profiles that can be used with Cisco Aironet CB21AG and PI21AG client adapters. The tool is meant to migrate profiles with minimal modification, but its behavior can be altered by command line options. The legacy 350 and CB20A profiles are not deleted or modified in any way.
Cisco expects the profile migration tool to be executed once, most likely immediately after installing or updating the CB21AG/PI21AG client adapter software. Upon completion, the profile migration tool may be removed from the user's system.
When the CB21AG/PI21AG client adapter software is installed, the Install Wizard also automatically installs the profile migration tool, unless the Don't Install option was chosen in ACAU. It is saved in the same directory as ADU.
Note If the Install Wizard is run without using an ACAU-generated configuration file, the profile migration tool is still installed automatically and saved in the same directory as ADU.
Note Profile migration tool 1.0 can be used only with ACAU and Install Wizard 2.5.
Note Refer to Appendix G of the Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration Guide (OL-4211-04) for more information on the profile migration tool.
These additional changes are available in ACAU 2.5:
•Certificate-based PEAP (EAP-MSCHAP V2) authentication is now available for the CB21AG and PI21AG client adapters.
•An Always Do User Authentication check box has been added to the Define Certificate window for EAP-TLS authentication. Checking this check box causes the client to switch from using machine authentication to using user authentication after the user logs on using his or her username and password. This is the default setting. Unchecking this check box causes the client to continue to use machine authentication after the user's computer logs into the domain.
•EAP-FAST PAC files are tied to the machine, so they cannot be used if copied to another machine.
