Using the Aironet System Tray Utility (ASTU)
Overview of ASTU
Overview of ASTU
ASTU is an optional application that provides a small subset of the features available through ADU.
Specifically, it enables you to access status information about your client adapter and perform basic
tasks. ASTU is accessible from an icon in the Windows system tray, making it easily accessible and
convenient to use. The ASTU icon appears only if a client adapter is installed into your computer and
you did not disable ASTU during installation.
ASTU provides information and options in the following ways:
•
In the appearance of the icon itself
•
Through a tool tip window that appears when you hover the cursor over the icon
•
Through a pop-up menu that appears when you right-click the icon
•
Through a Connection Status window that appears when you double-click the icon
The ASTU Icon
The appearance of the ASTU icon indicates the connection status of your client adapter. ASTU reads the
client adapter status and updates the icon every 1 to 5 seconds, depending on the value entered for the
Refresh Interval on the Display Settings window. Table 8-1 interprets the different appearances of the
ASTU icon.
Note
Windows 2000 and XP may display their own wireless network connection status icon in the system tray.
Cisco recommends that you turn off the Windows icon and use the ASTU icon to monitor your wireless
connection.
Table 8-1
Icon
Interpreting the ASTU Icon
Description
A white icon indicates that the client adapter’s radio is disabled.
A dark gray icon indicates that the client adapter is not associated to an access point (in
infrastructure mode) or another client (in ad hoc mode).
A light gray icon indicates that the client adapter is associated to an access point (in
infrastructure mode) or another client (in ad hoc mode) but the user is not EAP
authenticated.
A green icon indicates that the client adapter is associated to an access point (in
infrastructure mode) or another client (in ad hoc mode), the user is authenticated if the
client adapter is configured for EAP authentication, and the signal strength is excellent
or good.

You are not transmitting data and want to conserve battery power.
•
You are using a laptop on an airplane, hospital, or any other location where radio transmission is not
allowed and want to prevent the adapter’s transmissions from potentially interfering with the
operation of certain devices.
When the radio is enabled, it periodically sends out probes even if it is not associated to an access point
(in infrastructure mode) or another client (in ad hoc mode), as required by the 802.11 specification.
Therefore, it is important to disable it around devices that are susceptible to RF interference.
Note
If the client adapter’s radio is disabled, your client adapter is not associated, and a message appears when
you hover the cursor over the ASTU icon to inform you that the wireless network interface is disabled.

From this menu, you can choose between the following options:
•
Use Auto Profile Selection—Causes the client adapter’s driver to automatically select a profile
from the list of profiles that were set up in ADU to be included in auto profile selection.
If the client adapter loses association for more than 10 seconds (or for more than the time specified
by the LEAP/EAP-FAST authentication timeout value on the LEAP/EAP-FAST Settings window if
LEAP/EAP-FAST is enabled), the driver switches automatically to another profile that is included
in auto profile selection. The adapter will not switch profiles as long as it remains associated or
reassociates within 10 seconds (or within the time specified by the LEAP/EAP-FAST authentication
timeout value). To force the client adapter to associate to a different access point (in infrastructure
mode) or another client (in ad hoc mode), you must select a new profile.
Note
This option is available only if two or more profiles are included in auto profile selection.

Removing a Client Adapter
Removing a Client Adapter
Follow the instructions in this section to remove a PC-Cardbus card or PCI card from a computing
device, when necessary.
Caution
These procedures and the physical connections they describe apply generally to conventional Cardbus
slots and PCI expansion slots. In cases of custom or nonconventional equipment, be alert to possible
differences in Cardbus slot and PCI expansion slot configurations.
Removing a PC-Cardbus Card
To remove a PC-Cardbus card after it is successfully installed and configured (such as when your laptop
is to be transported), completely shut down your computer and pull the card directly out of the Cardbus
slot. When the card is reinserted and the computer is rebooted, your connection to the network should
be re-established.
Note
If you need to remove your PC-Cardbus card but do not want to shut down your computer, double-click
the Safely Remove Hardware icon in the Windows system tray, choose the Cisco Aironet client adapter
you want to remove under Hardware devices, click Stop, and click OK to close each open window. Then
pull the card directly out of the card slot.
Removing a PCI Card
Because PCI client adapters are installed inside desktop computers, which are not designed for portable
use, you should have little reason to remove the adapter. However, instructions are provided below in
case you need to remove your PCI card.
Step 1
Completely shut down your computer.
Step 2
Remove the computer cover.
Step 3
Remove the screw from the top of the CPU back panel above the PCI expansion slot that holds your client
adapter.
Step 4
Disassemble the antenna from the base.
Step 5
Pull up firmly on the client adapter to release it from the slot and carefully tilt the adapter to slip its
antenna through the opening near the slot.
Step 6
Reinstall the screw on the CPU back panel and replace the computer cover.

Resolving Resource Conflicts
If you encounter problems while installing your client adapter on a computer running a Windows
operating system, you may need to specify a different interrupt request (IRQ) or I/O range for the
adapter.
The default IRQ for the client adapter is IRQ 10, which may not work for all systems. Follow the steps
for your specific operating system to obtain an available IRQ.
During installation the adapter’s driver installation script scans for an unused I/O range. The installation
can fail if the I/O range found by the driver installation script is occupied by another device but not
reported by Windows. An I/O range might not be reported if a device is physically present in the system
but not enabled under Windows. Follow the steps for your specific operating system to obtain an
available I/O range.

Configuring the Client Adapter through the Windows XP Operating System
Overview
Overview
This appendix provides instructions for minimally configuring the client adapter through the Microsoft
Wireless Configuration Manager in Windows XP (instead of through ADU) as well as for enabling the
security options that are available for use with this operating system. The “Overview of Security
Features” section below describes each of these options so that you can make an informed decision
before you begin the configuration process.
In addition, this appendix also provides basic information on using Windows XP to specify the networks
to which the client adapter associates and to view the current status of your client adapter.
Note
If you require more information about configuring or using your client adapter with Windows XP, refer
to Microsoft’s documentation for Windows XP.
Overview of Security Features
When you use your client adapter with Windows XP, you can protect your data as it is transmitted
through your wireless network by encrypting it through the use of wired equivalent privacy (WEP)
encryption keys. With WEP encryption, the transmitting device encrypts each packet with a WEP key,
and the receiving device uses that same key to decrypt each packet.
The WEP keys used to encrypt and decrypt transmitted data can be statically associated with your
adapter or dynamically created as part of the EAP authentication process. The information in the “Static
WEP Keys” and “EAP (with Dynamic WEP Keys)” sections below can help you to decide which type
of WEP keys you want to use. Dynamic WEP keys with EAP offer a higher degree of security than static
WEP keys.
WEP keys, whether static or dynamic, are either 40 or 128 bits in length. 128-bit WEP keys offer a greater
level of security than 40-bit WEP keys.
Static WEP Keys
Each device within your wireless network can be assigned up to four static WEP keys. If a device
receives a packet that is not encrypted with the appropriate key (as the WEP keys of all devices that are
to communicate with each other must match), the device discards the packet and never delivers it to the
intended receiver.
You do not need to re-enter static WEP keys each time the client adapter is inserted or the Windows
device is rebooted because the keys are stored (in an encrypted format for security reasons) in the
registry of the Windows device. When the driver loads and reads the client adapter’s registry parameters,
it also finds the static WEP keys, unencrypts them, and stores them in volatile memory on the adapter.

Configuring the Client Adapter through the Windows XP Operating System
Overview
EAP (with Dynamic WEP Keys)
The standard for wireless LAN security, as defined by IEEE, is called 802.1X for 802.11, or simply
802.1X. An access point that supports 802.1X and its protocol, Extensible Authentication Protocol
(EAP), acts as the interface between a wireless client and an authentication server, such as a RADIUS
server, to which the access point communicates over the wired network.
Two 802.1X authentication types are available when configuring your client adapter through
Windows XP:
•
EAP-TLS—This authentication type uses a dynamic session-based WEP key derived from the
client adapter and RADIUS server to encrypt data. It uses a client certificate for authentication.
RADIUS servers that support EAP-TLS include Cisco Secure ACS release 3.0 or later and Cisco
Access Registrar release 1.8 or later.
•
Protected EAP (or PEAP)—One of the following PEAP authentication types are available,
depending on the software that is installed on your computer:
– PEAP (EAP-MSCHAP V2)—This PEAP authentication type is available if Cisco’s PEAP
security module (included in the Install Wizard file for Cisco Aironet 340, 350, and CB20A
client adapters) was not previously installed on your computer or was installed prior to Service
Pack 1 for Windows XP.
PEAP (EAP-MSCHAP V2) authentication is based on EAP-TLS authentication but uses a
password instead of a client certificate for authentication. PEAP (EAP-MSCHAP V2) uses a
dynamic session-based WEP key derived from the client adapter and RADIUS server to encrypt
data.
RADIUS servers that support PEAP (EAP-MSCHAP V2) authentication include Cisco Secure
ACS release 3.2 or later.
– PEAP (EAP-GTC)—Although this authentication type is not officially supported for CB21AG
and PI21AG client adapters, you may be able to use it successfully if Cisco’s PEAP security
module (included in the Install Wizard file for Cisco Aironet 340, 350, and CB20A client
adapters) was previously installed on your computer and installed after Service Pack 1 for
Windows XP.
PEAP (EAP-GTC) authentication is designed to support One-Time Password (OTP), Windows
NT or 2000 domain, and LDAP user databases over a wireless LAN. It is based on EAP-TLS
authentication but uses a password or PIN instead of a client certificate for authentication.
PEAP (EAP-GTC) uses a dynamic session-based WEP key derived from the client adapter and
RADIUS server to encrypt data. If your network uses an OTP user database, PEAP (EAP-GTC)
requires you to enter either a hardware token password or a software token PIN to start the EAP
authentication process and gain access to the network. If your network uses a Windows NT or
2000 domain user database or an LDAP user database (such as NDS), PEAP (EAP-GTC)
requires you to enter your username, password, and domain name in order to start the
authentication process.
RADIUS servers that support PEAP (EAP-GTC) authentication include Cisco Secure ACS
release 3.1 or later and Cisco Access Registrar release 3.5 or later.

Appendix E
Configuring the Client Adapter through the Windows XP Operating System
Overview
When you enable EAP on your access point and configure your client adapter for EAP-TLS or PEAP
using Windows XP, authentication to the network occurs in the following sequence:
1.
The client adapter associates to an access point and begins the authentication process.
Note
Note
The client does not gain full access to the network until authentication between the client
and the RADIUS server is successful.
2.
Communicating through the access point, the client and RADIUS server complete the authentication
process, with the password (PEAP) or certificate (EAP-TLS) being the shared secret for
authentication. The password is never transmitted during the process.
3.
If authentication is successful, the client and RADIUS server derive a dynamic, session-based WEP
key that is unique to the client.
4.
The RADIUS server transmits the key to the access point using a secure channel on the wired LAN.
5.
For the length of a session, or time period, the access point and the client use this key to encrypt or
decrypt all unicast packets (and broadcast packets if the access point is set up to do so) that travel
between them.
Refer to the IEEE 802.11 Standard for more information on 802.1X authentication and to the following
URL for additional information on RADIUS servers:

6a00800ca7ab.html
WPA
Wi-Fi Protected Access (WPA) is a standards-based security solution from the Wi-Fi Alliance that
provides data protection and access control for wireless LAN systems. It is compatible with the IEEE
802.11i standard but was implemented prior to the standard’s ratification. WPA uses Temporal Key
Integrity Protocol (TKIP) and 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 passphrase (also known
as WPA pre-shared key or WPA-PSK). Using WPA, 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
passphrase, however, you configure a passphrase (or pre-shared key) on both the client and the access
point, and that passphrase is used as the PMK.
In order to use WPA, your computer must be running Windows XP Service Pack 2.
Note
WPA must also be enabled on the access point. Access points must use Cisco IOS Release 12.2(11)JA
or later to enable WPA. Refer to the documentation for your access point for instructions on enabling
this feature.

Follow the steps below to configure your client adapter using Windows XP.
Note
These instructions assume you are using the Windows XP classic view rather than the category view.
Otherwise, the windows you see will look different than those shown in this section.
Note
The appropriate certificates must be installed on your computer if you are planning to enable EAP-TLS
or PEAP authentication. EAP-TLS requires both a Certificate Authority (CA) certificate and a user
certificate while PEAP requires only a CA certificate. Contact your system administrator if you need
help obtaining and importing the necessary certificates.
Step 1
Make sure the client adapter’s driver has been installed and the client adapter is inserted in the Windows
XP device.
Step 2
Double-click My Computer, Control Panel, and Network Connections.
Step 3
Right-click Wireless Network Connection.
Step 4
Click Properties. The Wireless Network Connection Properties window appears.

Configuring the Client Adapter
Step 10
Step 11
Choose one of the following options from the Network Authentication drop-down list:
•
Open—Enables your client adapter, regardless of its WEP settings, to authenticate and attempt to
communicate with an access point. However, communication can occur only if the adapter’s WEP
key matches that of the access point. If your adapter is not using WEP, it will not attempt to
authenticate to an access point that is using WEP and vice versa. This option is recommended if you
want to use static WEP or EAP authentication without WPA.
•
Shared—Enables your client adapter to authenticate and communicate only with access points that
have the same WEP key. Cisco recommends that shared key authentication not be used because it
presents a security risk.
Note
Your client adapter’s network authentication setting must match that of the access points
with which it is to communicate. Otherwise, your client adapter may not be able to
authenticate to them.
Note
EAP-TLS does not work with shared key authentication because shared key authentication
requires the use of a WEP key, and a WEP key is not set for EAP-TLS until after the
completion of EAP authentication.
•
WPA—Enables WPA, which enables your client adapter to associate to access points using WPA.
•
WPA-PSK—Enables WPA pre-shared key (WPA-PSK), which enables your client adapter to
associate to access points using WPA-PSK.
Note
The WPA-None option is not supported for use with the CB21AG or PI21AG client adapter.
Note
Refer to the “WPA” section on page E-56 for more information on WPA and WPA-PSK.
Choose one of the following options from the Data encryption drop-down list:
•
Disabled—Disables data encryption for your client adapter. This option is available only when
Open or Shared has been selected for Network Authentication.
•
WEP—Enables static or dynamic WEP for your client adapter. This option is recommended for use
with open authentication.
•
TKIP—Enables Temporal Key Integrity Protocol (TKIP) for your client adapter. This option is
recommended for use with WPA and WPA-PSK unless the access point to which your client adapter
will associate supports AES.
•
AES—Enables the Advanced Encryption Standard (AES) encryption algorithm for your client
adapter. This option provides a stronger encryption mechanism than TKIP and is therefore
recommended for use with WPA and WPA-PSK, provided the access point to which your client
adapter will associate supports AES.

Step 12
Follow the steps below to enter a static WEP key if you are planning to use static WEP.
If you are planning to use EAP-TLS or PEAP authentication, which uses dynamic WEP, go to
Step 13.
Note
a.
Make sure the The key is provided for me automatically check box is unchecked.
b.
Obtain the WEP key for the access point (in an infrastructure network) or other clients (in an ad hoc
network) from your system administrator and enter it in both the Network key and Confirm network
key fields. Follow the guidelines below to enter a new static WEP key:
WEP keys must contain the following number of characters:
•
–10 hexadecimal characters or 5 ASCII text characters for 40-bit keys
Example: 5A5A313859 (hexadecimal) or ZZ18Y (ASCII)
–26 hexadecimal characters or 13 ASCII text characters for 128-bit keys
Example: 5A583135333554595549333534 (hexadecimal) or ZX1535TYUI354 (ASCII)
Note
Your client adapter’s WEP key must match the WEP key used by the access point (in
infrastructure mode) or clients (in ad hoc mode) with which you are planning to communicate.
•
c.
In the Key index (advanced) field, choose the number of the WEP key you are creating (1, 2, 3, or 4).
Note
d.
Step 13
Step 14
ASCII text WEP keys are not supported on Cisco Aironet 1200 Series Access Points, so
you must enter hexadecimal characters if your client adapter will be used with these
access points.
The WEP key must be assigned to the same number on both the client adapter and the access
point (in an infrastructure network) or other clients (in an ad hoc network).
Click OK to save your settings and to add this SSID to the list of preferred networks (see
Figure E-1). The configuration is complete for static WEP. The client adapter automatically attempts
to associate to the network(s) in the order in which they are listed.
If you enabled WPA-PSK, obtain the pre-shared key for the access point from your system administrator
and enter it in both the Network key and Confirm network key fields. Follow the guidelines below to
enter a pre-shared key:
•
Pre-shared keys must contain 8 to 63 ASCII text characters or 64 hexadecimal characters.
•
Your client adapter’s pre-shared key must match the pre-shared key used by the access point with
which you are planning to communicate.
Check the The key is provided for me automatically check box if you are planning to use EAP-TLS
or PEAP, which uses dynamic WEP keys.
Note
This parameter is not available if you enabled WPA or WPA-PSK.

Performing a Site Survey
Overview
Overview
Note
This appendix applies only to people who are responsible for conducting a site survey to determine the
best placement of infrastructure devices within a wireless network.
The site survey utility can assist you in conducting a site survey. The utility operates at the RF level and
is used to determine the best placement and coverage (overlap) for your network’s infrastructure devices.
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).
The site survey utility operates in a passive mode. That is, it does not initiate any RF network traffic; it
simply listens to the traffic that the client adapter hears and displays the results.
Guidelines
Keep the following guidelines in mind when preparing to perform a site survey:
•
Perform the site survey when the RF link is functioning with all other systems and noise sources
operational.
•
Execute the site survey entirely from the mobile station.
Additional Information
Also consider the following operating and environmental conditions when performing a site survey:
Note
•
Data rates—Sensitivity and range are inversely proportional to data bit rates. Therefore, the
maximum radio range is achieved at the lowest workable data rate, and a decrease in receiver
threshold sensitivity occurs as the radio data increases.
•
Antenna type and placement—Proper antenna configuration is a critical factor in maximizing
radio range. As a general rule, range increases in proportion to antenna height.
•
Physical environment—Clear or open areas provide better radio range than closed or filled areas.
Also, the less cluttered the work environment, the greater the range.
•
Obstructions—A physical obstruction such as metal shelving or a steel pillar can hinder the
performance of wireless devices. Avoid placing these devices in a location where a metal barrier is
between the sending and receiving antennas.
•
Building materials—Radio penetration is greatly influenced by the building material used in
construction. For example, drywall construction allows greater range than concrete blocks, and
metal or steel construction is a barrier to radio signals.
Refer to the hardware installation guide for your infrastructure device for additional information on
factors affecting placement.

Opening the Site Survey Utility
Opening the Site Survey Utility
To open the site survey utility, choose Start > Programs > Cisco Aironet > Aironet Site Survey Utility.
Note
If you specified a different program folder during installation, you must access the site survey utility
from that folder.
Note
The site survey utility is installed on your computer only if you checked the Install Site Survey Utility
check box during the installation of the client adapter software. If you did not check this check box and
want to use the site survey utility, uninstall the client adapter software and reinstall it, making sure to
check the site survey check box.
Selecting the Client Adapter
Note
The site survey utility can be used only with CB21AG and PI21AG client adapters.
When the site survey utility starts, it scans for client adapters. If only one adapter is detected, it is
selected automatically. However, if the utility detects multiple adapters or no adapters, the Select
Adapter window appears (see Figure F-1).
Note
You can manually open this window at any time to select a different client adapter. Simply choose Select
Adapter from the site survey utility’s Action drop-down menu.

The log entries are time-stamped and appear in ASCII text. Each line typically represents a different
access point.
Note
If the Accumulate button is depressed when you click Log Snapshot, two timestamps appear on each
line. The timestamp in column one of the log file is the time when the log entry is made. The second
timestamp, which appears only when the Accumulate button is depressed, is the Time of Day. This value
indicates the date and time when the signal strength of each access point was at its maximum. Both
timestamps appear in this format: 2005-07-20 16:13:09. The time is based on a 24-hour clock. For
example, the first two lines in Figure F-7 show only one timestamp while the remaining lines show both
timestamps.
Note
As an alternative to using the Log Snapshot button, you can configure the site survey utility to
automatically copy the contents of the AP scan list to a log file using the AP Scanning drop-down menu
options. See the “Using AP Scanning” section on page F-96 for more information.

Performing a Site Survey
Using the Proximity Beeper
Viewing an Accumulation of Access Points
Clicking the Accumulate 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 detected previously from that
access point. The Time of Day field, which appears only in Accumulate mode, indicates the date and
time when the signal strength of each access point was at its maximum.
The Accumulate mode provides a convenient way to list all access points within a facility, not just those
that may be visible at one time from a particular location. By using the information in the Time of Day
field with a site map and a wristwatch, you may be able to determine the approximate location of each
access point in the list.
Note
Clicking the Accumulate button again deactivates the Accumulate mode and returns the current AP scan
list.
Note
You can use the Save AP Scan List and Open AP Scan List options in the AP Scanning drop-down menu
to save and reload accumulated scan lists back into the application at a later time.
Using the Proximity Beeper
You can use the site survey utility’s proximity beeper 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.
Configuring the Proximity Beeper
Follow these steps to configure the proximity beeper.
Step 1
Choose Options from the site survey utility’s Action drop-down menu. The Options window appears
(see Figure F-8).

Site Survey Utility - Options Window
Choose one of these options on which the proximity beeper will be based:
Proximity Beeper Option
Description
Signal Strength
The beeper sounds as an access point’s signal becomes stronger.
Note
Step 3
This is the default value.
Noise Level/Signal Quality
The beeper sounds as the level of background radio frequency energy
decreases or the signal quality of the most recently received packets
improves.
Signal-to-Noise Ratio/
Overall Link Quality
The beeper sounds as the client adapter’s ability to communicate with
an access point improves.
Link Speed
The beeper sounds as the transmit rate of data packets between the
client adapter and an access point becomes faster.
Perform one of the following to set the tone of the proximity beeper:
•
Uncheck the Invert Tone of Proximity Beeper check box if you want the beeper’s rate and pitch to
increase in response to the option selected in Step 2. The beeps become more alarming as the client
adapter moves closer to an access point, enabling you to identify areas of good coverage. This is the
default setting.
•
Check the Invert Tone of Proximity Beeper check box if you want the beeper’s rate and pitch to
decrease in response to the option selected in Step 2. The beeps become more alarming as the client
adapter approaches areas of weaker coverage.
Step 4
Click OK to save your changes.

Step 2
Check the check box and select a numerical value for each condition below that you want to cause the
contents of the AP scan list to be automatically copied to a log file. You can check one or both.
Condition
Description
Every XXX seconds
Causes the contents of the AP scan list to be copied to a log file after a
specified amount of time elapses. For example, if you set the value to
60, the AP scan list is logged to a file every 60 seconds.
Default: Unchecked; 10 seconds
When the number of APs in
the scan list crosses this
threshold
Causes the contents of the AP scan list to be copied to a log file
whenever the number of access points in the scan list reaches or crosses
over the specified threshold value. For example, if you set the value to
5, the AP scan list is logged to a file each time the number of access
points in the scan list rises to or above 5 or falls to or below 5. However,
if the number of access points in the scan list stays at 5, continuous
triggers are not generated.
Default: Unchecked; 3

Using the Profile Migration Tool
Overview of the Profile Migration Tool
Overview of the Profile Migration Tool
The profile migration 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 your computer.
Note
Profile migration tool 1.0 can be used only with Install Wizard 2.5. To find the current version number
of the profile migration tool, find the PMT.exe file in the directory where ADU is installed, right-click
the file, and click Properties and the Version tab.
Rules Governing Profile Migration
These rules govern the operation of the profile migration tool:
•
Legacy profiles that are configured for host-based EAP are not migrated.
•
Passwords that are stored in LEAP and EAP-FAST profiles may or may not be migrated, depending
on the encryption method used for those passwords. Passwords that are not migrated must be
re-entered after the migration.
•
The PAC files for EAP-FAST profiles are not migrated. They must be reprovisioned after the
migration.
•
A profile’s auto profile selection properties are migrated only if auto profile selection is enabled.
•
Legacy profiles that were created using older versions of ACU may experience problems during
migration. In such cases, the profile migration tool migrates the information that it can and ignores
any additional information.
•
If multiple instances of the same profile name exist, the names are mangled unless overridden by
command line options. The default name-mangling scheme causes subsequent profiles with the
same name to have an _a or _b appended to the end of the name, indicating whether the profile
migrated from an 802.11a (CB20A) or 802.11b (350) radio. A third instance would have an _aa or
_bb appended and so on (for example, Office, Office_a, Office_aa).
Note
If the original name is too long to be appended, it is shortened by truncating as necessary.

can be migrated is 16 minus the number of existing CB21AG and PI21AG profiles. If the number of
profiles to migrate is greater than the number of profiles that can be migrated, some legacy profiles
are not migrated. In this case, the client adapter priority is as follows, unless overridden by command
line options:
1. 350 PCMCIA
2. 350 PCI
3. 350 mini PCI
4. CB20A
For each client adapter, profiles are migrated in this order:
1. Default profiles
2. Auto-selectable profiles
3. Any current profiles for inserted legacy client adapters that have not already been migrated
4. Any remaining profiles
•
Profile names that existed before the migration are preserved unless the -replace command is
executed.
Installing the Profile Migration Tool
When you install the client adapter software, the Install Wizard automatically installs the profile
migration tool, unless your system administrator used an administrative tool to prevent its installation.
It is saved in the same directory as ADU.
Note
The name of the PMT installation log is migrate.log. It is saved at the root level of your hard drive (C:\).

Using the Profile Migration Tool
Running the Profile Migration Tool
Running the Profile Migration Tool
Follow these steps to run the profile migration tool to migrate your 350 and CB20A profiles to
CB21AG/PI21AG profiles.
Note
The best time to run the profile migration tool is immediately after the Install Wizard has installed the
client adapter software.
Note
The following conditions must be true before the profile migration tool can be run successfully:
- Your computer must contain the 350 and CB20A profiles that you want to migrate.
- ADU must be installed on the same computer but must not be running during the profile migration.
- A CB21AG or PI21AG client adapter must be inserted into your computer.
Step 1
Perform one of the following:
•
If the profile migration tool runs automatically after the Install Wizard installs the client adapter
software, go to Step 4.
•
If you want to manually activate the profile migration tool, open the Windows Command Prompt
from Start > Programs > Accessories. Go to Step 2.
Step 2
Use MS-DOS commands to access the directory where the profile migration tool (PMT.exe) is located
on your computer.
Step 3
Type PMT and press Enter. The profile migration tool runs and displays the results.
Note
See the “Command Line Options” section below if you want to alter the behavior of the profile
migration tool before running it.
Step 4
Restart your computer.
Step 5
Open ADU. Your migrated 350 and CB20A profiles now appear as CB21AG/PI21AG profiles on the
Profile Management window and are ready for use.
Step 6
Re-enter the WEP keys in ADU.
Step 7
If desired, you can view the log file generated by the profile migration tool. This file shows the profiles
that were processed, their status, and the reason why any profiles were not migrated.
Note
Step 8
Unless you changed the default name and location of the log file using the -logfile command,
you can find the log file at C:\migrate.log.
If desired, you can remove the profile migration tool from your computer.

Using the Profile Migration Tool
Command Line Options
Command Line Options
These command line options can be used to alter the behavior of the profile migration tool. The correct
format is PMT -command.
Note
Leave a space between multiple commands (such as -command -command).
•
-AllowReRun—Enables the profile migration tool to be run multiple times. When you rerun the
tool, it migrates all the existing profiles, even the ones that were already migrated. If you have
modified any of the previously migrated profiles, the modifications are lost.
Example:
Note
•
If you do not use this command, you can run the profile migration tool only once. If you
attempt to run it again, a message appears indicating that the profiles have already been
migrated and that the tool does not need to be run again.
-CardOrder  ...—Specifies the order in which profiles are migrated when
multiple client adapters are selected.
Example:
•
PMT -AllowReRun
PMT -CardOrder -pci350 -pcmcia350
-CB20A—Selects only CB20A profiles for migration. This command can be used alone or in
conjunction with the -CardOrder  ... command to specify the order in
which client adapter profiles are migrated.
Examples: PMT -CB20A
PMT -CardOrder -CB20A -pcmcia350
•
-ConfigFile  ...—Enables you to run the profile migration tool using
multiple command lines that are specified within one or more configuration files. You can create the
configuration file(s) using a text editor such as Notepad. To do so, simply type the desired
commands (such as -miniPCI -replace) in the text editor and save the file. (Do not include PMT
when typing the commands in the text editor.) After you have created the configuration file(s), use
the -ConfigFile command with the file(s) you created.
Examples: PMT -ConfigFile filename1.txt
PMT -ConfigFile filename1.txt filename2.txt
Note
If more than one file is specified, the profile migration tool performs all its functions for each
file. It ignores all other command line options and executes only the options in the file(s) in
order to prevent confusion regarding command priority.

Using the Profile Migration Tool
Command Line Options
•
-logfile —Enables you to change the name and location of the log file, which
identifies the migrated and unmigrated profiles after you run the profile migration tool. The default
name is migrate.log, and its default location is the system drive root (for example, C:).
Examples: PMT -logfile logfile.log
PMT -logfile C:\Cisco Aironet\migrate.log
•
Note
If you specify a new location for the log file, that location must already exist. Otherwise, the
file is saved to the system drive root (for example, C:).
Note
If the -logfile command is used without the  parameter, a log file is not
generated.
-miniPCI—Selects only 350 mini PCI profiles for migration. This command can be used alone or
in conjunction with the -CardOrder  ... command to specify the order in
which client adapter profiles are migrated.
Examples: PMT -miniPCI
PMT -CardOrder -CB20A -miniPCI -pci350
•
-pci350—Selects only 350 PCI profiles for migration. This command can be used alone or in
conjunction with the -CardOrder  ... command to specify the order in
which client adapter profiles are migrated.
Examples: PMT -pci350
PMT -CardOrder -miniPCI -pci350
•
-pcmcia350—Selects only 350 PCMCIA profiles for migration. This command can be used alone
or in conjunction with the -CardOrder  ... command to specify the order
in which client adapter profiles are migrated.
Examples: PMT -pcmcia350
PMT -CardOrder -pcmcia350 -pci350
•
-replace—Causes legacy profiles with the same name as existing CB21AG/PI21AG profiles to
replace the existing profiles. This command is intended to minimize the number of similarly named
profiles on your system.
For example, if both a 350 PCI legacy profile and a CB21AG profile have the same name (such as
Office), the legacy profile replaces the CB21AG profile, resulting in only one Office profile. If this
command is not used, you have two profiles after migration: Office and Office_b.
Example:
Note
PMT -replace
If you have multiple legacy profiles with the same name (such as Home), only one Home
profile is available after migration.

VLAN
A switched network that is logically segmented, by functions, project teams, or applications rather than
on a physical or geographical basis. For example, all workstations and servers used by a particular
workgroup team can be connected to the same VLAN regardless of their physical connections to the
network or the fact that they might be intermingled with other teams. You use VLANs to reconfigure
the network through software rather than physically unplugging and moving devices or wires.
A VLAN consists of a number of end systems, either hosts or network equipment (such as bridges and
routers), connected by a single bridging domain. The bridging domain is supported on various pieces
of network equipment such as LAN switches that operate bridging protocols between them with a
separate group for each VLAN.
