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 iconThe ASTU IconThe 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 Interpreting the ASTU IconIcon DescriptionA 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.

When you choose this option, the Enter Wireless Network Password window appears. Enter your LEAP or EAP-FAST credentials and click OK. The LEAP or EAP-FAST Authentication Status window appears, and the authentication process begins.Note Refer to Chapter 5 for information on setting a manual LEAP or EAP-FAST profile and Chapter 6 for details on the authentication process.ReauthenticateThis option forces your client adapter to try to reauthenticate using the username and password of the current profile. It is available for all EAP-enabled profiles. When you choose this option, the authentication process begins.If your client adapter is unable to authenticate using the specified username and password, you may be prompted to re-enter them. If you click Cancel, a message appears indicating that the current profile will be disabled until you choose the Reauthenticate option, reboot your computer, or eject and reinsert the client adapter.Select ProfileThis option enables you to select the active profile for your client adapter. When you choose this option, a profiles submenu appears (see Figure 8-4).Figure 8-4 Profiles SubmenuFrom 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.

E-54Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration GuideOL-4211-05Appendix E Configuring the Client Adapter through the Windows XP Operating SystemOverviewOverviewThis 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 FeaturesWhen 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 KeysEach 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.
E-55Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration GuideOL-4211-05Appendix E Configuring the Client Adapter through the Windows XP Operating SystemOverviewEAP (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 throughWindows 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.
E-56Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration GuideOL-4211-05Appendix E Configuring the Client Adapter through the Windows XP Operating SystemOverviewWhen 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 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.Note 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:http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_configuration_guide_chapter09186a00800ca7ab.htmlWPAWi-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.

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.Step 11 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.

In the Key index (advanced) field, choose the number of the WEP key you are creating (1,2,3, or 4).Note 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).d. 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.Step 13 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.Step 14 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.

F-72Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration GuideOL-4211-05Appendix F Performing a Site SurveyOverviewOverviewNote 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.GuidelinesKeep 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 InformationAlso consider the following operating and environmental conditions when performing a site survey:•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.Note Refer to the hardware installation guide for your infrastructure device for additional information on factors affecting placement.

It is shown only if the access point was configured with a name, Aironet Extensions are enabled (on access points running Cisco IOS Release 12.2(4)JA or later), and the access point transmits this information.Note This field shows up to 15 characters although the name of the access point may be longer.Device Type The access point’s model number.Radio Type The type of radio used in the access point.Hops The number of hops that the packets must take to get to the root. For example, if there is a repeater between your client adapter and the access point to which it is associated, the number of hops is 1.Load The access point’s channel utilization in terms of traffic and throughput.Note This parameter is shown only if the access point is using QoS Basis Service Set (QBSS) or call admission control (CAC). If neither is used, this field is left blank. If both are used, the value comes from the QBSS.CWmin The minimum value used by the access point to calculate a contention window (CW).Note Contention occurs when two or more radios in the same area try to transmit at the same time. When this occurs, the radios wait for a certain amount of time before trying again. Because contention can occur more than once, the radios use a series of progressively longer wait periods, or “windows,” each time they encounter contention for a given packet.CWmax The maximum value used by the access point to calculate a contention window (CW).Note Contention occurs when two or more radios in the same area try to transmit at the same time. When this occurs, the radios wait for a certain amount of time before trying again. Because contention can occur more than once, the radios use a series of progressively longer wait periods, or “windows,” each time they encounter contention for a given packet.Associations The number of associations currently being maintained by the access point.CCX Version The version of Cisco Compatible Extensions (CCX) supported by the access point.Table F-3 Site Survey Utility - AP Detailed Information (continued)Detailed Information Parameter Description

The “Logged current AP Scan List” message appears below the scan list, and the log file is saved. The default filename is SST_APScanLog.txt, and the default location is the directory where the site survey utility is installed. Note If desired, you can change the filename and its location using the AP Scan List Logging Configuration window. See the “Configuring AP Scan Logging” section on page F-96 for more information.If the AP scan list is paused when you click Log Snapshot, the currently displayed data (not the latest available data) is added to the log. Each time you click Log Snapshot, the new scan list is written at the end of the existing log file.To view the log file, choose View AP Scan Log from the AP Scanning drop-down menu. The log file opens in the configured viewer (see Figure F-7).Note The log file can be viewed in Notepad or any other viewer. However, because it is written in a comma-separated values (CSV) format, it can also be opened by a spreadsheet or database program (such as Microsoft Excel). If the file is renamed with a .csv extension, Microsoft Excel would automatically place the values in separate columns.Power Limit The power limit that the access point has set for the client adapter. It is shown in milliwatts (mW).RM-Normal RM-APScan RM-CliWlkIndicates that the access point is using radio management. RM-Normal indicates normal status, RM-APScan indicates AP radio scan, and RM-CliWlk indicates client walkabout.

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.

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 BeeperYou 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 BeeperFollow 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).

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 5 Follow the instructions in the “Enabling the Proximity Beeper” section below to enable the proximity beeper.Proximity Beeper Option DescriptionSignal Strength The beeper sounds as an access point’s signal becomes stronger.Note 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 QualityThe 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.

G-106Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration GuideOL-4211-05Appendix G Using the Profile Migration ToolOverview of the Profile Migration ToolOverview of the Profile Migration ToolThe 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 Versi on tab.Rules Governing Profile MigrationThese 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.
G-107Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration GuideOL-4211-05Appendix G Using the Profile Migration ToolInstalling the Profile Migration Tool•CB21AG and PI21AG client adapters have a limit of 16 profiles, so the total number of profiles that 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 PCMCIA2. 350 PCI3. 350 mini PCI4. CB20AFor each client adapter, profiles are migrated in this order:1. Default profiles2. Auto-selectable profiles3. Any current profiles for inserted legacy client adapters that have not already been migrated4. Any remaining profiles•Profile names that existed before the migration are preserved unless the -replace command is executed.Installing the Profile Migration ToolWhen 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:\).
G-108Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration GuideOL-4211-05Appendix G Using the Profile Migration ToolRunning the Profile Migration ToolRunning the Profile Migration ToolFollow 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 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.Step 8 If desired, you can remove the profile migration tool from your computer.

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: PMT -AllowReRunNote 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 <cardtype> <cardtype>...—Specifies the order in which profiles are migrated when multiple client adapters are selected.Example: PMT -CardOrder -pci350 -pcmcia350•-CB20A—Selects only CB20A profiles for migration. This command can be used alone or in conjunction with the -CardOrder <cardtype> <cardtype>... command to specify the order in which client adapter profiles are migrated.Examples: PMT -CB20APMT -CardOrder -CB20A -pcmcia350•-ConfigFile <filename> <filename>...—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 PMTwhen 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.txtPMT -ConfigFile filename1.txt filename2.txtNote 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.
G-110Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration GuideOL-4211-05Appendix G Using the Profile Migration ToolCommand Line Options•-logfile <logfile name>—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.logPMT -logfile C:\Cisco Aironet\migrate.logNote 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 <logfile name> 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 <cardtype> <cardtype>... command to specify the order in which client adapter profiles are migrated.Examples: PMT -miniPCIPMT -CardOrder -CB20A -miniPCI -pci350•-pci350—Selects only 350 PCI profiles for migration. This command can be used alone or in conjunction with the -CardOrder <cardtype> <cardtype>... command to specify the order in which client adapter profiles are migrated.Examples: PMT -pci350PMT -CardOrder -miniPCI -pci350•-pcmcia350—Selects only 350 PCMCIA profiles for migration. This command can be used alone or in conjunction with the -CardOrder <cardtype> <cardtype>... command to specify the order in which client adapter profiles are migrated.Examples: PMT -pcmcia350PMT -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: PMT -replaceNote If you have multiple legacy profiles with the same name (such as Home), only one Homeprofile is available after migration.
