Introduction to the Client Adap ter s

Introduction to the Client Adapters

The Cisco Aironet 340, 350, and CB20A Wireless LAN Client Adapters are radio modules that provide transparent wireless data communications between fixed, portable, or mobile devices and other wireless devices or a wi red netw ork in frastru cture. The clie nt adap ters a re fully c ompatib le when used in de vic es supporting Plug-and- Play (PnP ) techno logy.

The primary function of the client adapters is to transfer data pack ets transparen tly through the wirele ss infrastructure through an access point connected to a wired LAN. The adapters operate similarly to a standard network product except that th e cable is replace d with a radi o connec tion and an ac cess poin t is required to make the c onn ect ion to t h e wi re. No spe cia l w ire les s ne twor king fu nctio ns are r equi red, and all existing applications that operate over a network can operate using the adapters.

This document c overs the five client a dapt ers de scr ibed in Table 1-1.

Note In the first three product model numbers, the f irs t x represents the client adapter series (340 or 350), and

the second x indicates the wired equivalent privacy (WEP) level of the card, where 0 = no WEP capability , 1 = 40-bit WEP, and 2 = 128-bit WEP. If the last two product model numbers contain K9, the card is 128-bit W EP ca pabl e.

Terminology

The following terms a re u sed thr ough out t his d oc ume nt:

• client adapter—Refers to all five types of adapters.

• PC card, LM card, PC I ca rd , mini PCI card, or PC-Cardbus card—Refers to a specific adapter.

• workstati on (or station )—Refers to a computing device with an installed client adapter.

• infrastructure device—Refers to a device that connects client adapters to a wired LAN, such as an

access point, bridge, or ba se station . Throughou t this doc ument, access point is used to represent infrastructure d evices in ge nera l.

Hardware Components

The client adapte r has three m ajor ha rdware compon en ts: a radio , a radio an tenna, and two LED s.

Radio

Different radios are used for the 2 .4-GHz an d 5-GHz cl ient ada pters:

• The Cisco Aironet 340 and 350 series PC, LM, PCI, and mini PCI cards are IEEE 802.11b-compliant

client adapters. They contain a direct-sequence spread spectrum (DSSS) radio that operates in the

2.4-GHz Industrial Scientific Medical (ISM) license-free band. The 340 series 30-milliwatt (mW) radio and the 350 se r ies 1 00- mW ra dio tran smi t da ta over a half- dup lex radi o cha nn el o pera ting a t up to 11 Mbps. These cards operate with other IEEE 802.11b-compliant client devices in ad hoc (or peer-to-peer) mode or w ith Cisco Air onet 340, 350, 11 00, and 12 00 Series Acc ess Points (wi th a

2.4-GHz radio) a nd oth er I EE E 802 .11 b-c ompl ia nt i nfra struc tur e devices in inf ra struc ture mod e. They are approved for indoor and outdoor use.

DSSS technology distributes a radio signal over a wide range o f fre quen cies and then return s the signal to the original fr eq ue ncy range at th e rec eiver. The benefit of this technology is its a bilit y to protect the dat a t r an smission fr om int e rfer en ce . For exam ple, if a part ic ula r f requ ency en co unte rs noise or interference or both, enough redundancy is built into the signal on other frequencies that the client adapter usually will still be successful in its transmission.

• The Cisco Airone t A IR-CB2 0A PC- Cardbus ca r d is an I EEE 802 .11a- co mplia nt c li ent ada pter. It

contains an orthogonal frequ ency division multiplexing (OFDM) radio t hat opera tes in the Unlicensed National Information Infrastructure (UNII) 1 and UNII 2 license-free bands located in the lower 5-GHz port ion of the rad io fre quency sp ec tru m. The 20 -m W rad io t rans mi ts data over a half-duplex radio c ha nn el opera tin g at up to 5 4 M bp s. Th is c ard in tero pe rat es w ith oth er IEE E

Chapter 1 Product Overview

Hardware Components

Radio Antenna

The type of antenna use d depends on you r clie nt adapte r:

• PC cards have an integrated, permanently attached diversity antenna. The benefit of the diversity

antenna system is improved coverage. The system works b y allowing the card to switch and sample between its two antenna ports in order to select the optimum port for receiving data packets. As a result, the card has a better chance of maintaining the radio frequency (RF) connection in areas of interference. The anten n a is ho u sed with in the sec tion of the card th at h angs o ut of the PC car d slot when the card is installed.

• LM cards are shipped with out an antenn a; ho w e v er, an antenna can be connected through the car d’s

external connec tor.

• PCI cards are shipped with a 2-dB i dipole an tenna t hat atta ches to th e card ’s antenna connector.

However, other types of antennas may be used. PCI cards can be operated through only the primary (or right) anten na port .

• Mini PCI cards are designed to be used with either one or two antennas, which connect to the card’s

two antenna connectors. If two antennas are used, the radio automatically selects the antenna that presents the best RF si gnal . If on ly o ne a nte nna i s used, the r adio finds and uses it r egardless of which connector it is plugged into.

• PC-Cardbus card s hav e an inte grate d, perman ently attach ed non-di v ersity an tenna that co ntains t wo

antenna ports, one for tra nsm it tin g and on e fo r re ceiving. T he ca rd cann ot sw it ch a nd sa mple between the ports. The antenna is housed within the section of the card that hangs out of the Cardbus slot when the card is installed.

Note Refer to the Antenna Mode (Transmit and Receive) parameters in Table 5-4 a nd Table 5-5 for

information on setting the client adapter’s ant enna mod e.

Note External antennas used in c ombination with a po wer setting r esulting in a radia ted power lev el abov e 100

mW equivalent isotropic radiated power (EIRP) are not allowed for use within the European community and other countries th at ha ve adop ted the Euro pean R&TTE d irecti v e or the CEPT recommenda tion Rec

70.03 or both. For more details on legal comb ination s of power levels and antennas in those coun tries, refer to the “De cla rat ion of Con formi ty w ith Regar d t o the R&TT E Di rect ive 1999/5 /EC” section on

page C-4 and the “Maximum Power Levels and Antenna Gains” section on page D-4.

LEDs

The client adapters have two LEDs that glow or blink to indicate the status of the adapter or to convey error messages. Refer to Chapte r 10 for an interpretation of the LED codes.

Note Mini PCI cards do not have LEDs.

Software Components

The client adapter has three major software components: radio firmware, a driver, and client utilities. These components are installed together by running a single Install Wizard file that is available from Cisco.com. This file can be run on Windows 98, 98 SE, NT, 2000, Me, or XP and can be used with any of the following client adapter types:

• 340 and 350 series PC, LM, and PCI car ds

• 350 series mini PCI ca rds

• PC-Cardbus (CB20A) card s

Chapter 3 provides instructions on using the Install Wizard to install or upgrade these software

components.

Note Prior to the release of the Install Wizard file, each software component had to be installed separately.

This version of the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows pertains specifically to versions of the software that are available through the Install

Wizard. If you are using, installing, or upgrading to versions of client adapter software that do not use the Install Wizard, refer to version OL- 139 4-0 4 o f th is m an ua l fo r in for mat ion an d ins tr uct ions.

Radio Firmware

The firmware controls the client adapter ’s radio. The c lient adapter is shipped with the firmware installed in Flash memory. However, Cisco recommends that you always use the latest version. You can upgrade the client adapter’s firmware in three ways:

• Through the Install Wizard—The Install Wizard automatically upgrades the client adapter’s

firmware to the version included in the Install Wizard file.

• Through the dr iv er—The drive r included in the Install Wiz ard file is also bundled with clien t adapter

firmware. Each time you insert a c lient adapt er or rebo ot your compute r, the driver loads and may install the firmware with which it is bu ndled (if that firmware is newer than the firmware that is currently installed in the adapter). You can use the Install Wizard’s Disable Firmware Checking parameter or ACU’s Automatically Load New Firmware When NDIS Driver Is Updated parameter to specify whethe r the driver upgrades the firmware . Refer to page 3-6 and page 9 -10 fo r mor e information.

• Through ACU—The Load Firmware icon or Load New Firmware menu option in ACU enables you

to upgrade the c l ient ad ap te r’s firmware from an image (*.img) file that contains only firmware. Refer to the “Upgrading the Firmware” section on page 9-8 for more information.

Driver

The driv er pr ovi des an interfa ce be tween a c omputer runnin g a W i ndo ws op erating s ystem and the client adapter, thereby enabling Windows and the applications it runs to communicate with the adapter. The driver must be installed before the adapter can be used.

Client Utilities

T wo client utilities are av ailable for use with Cisco Airo net client adapters: Aironet Clien t Utility (A CU) and Aironet Client Monitor (ACM). These utilities are optional applications that interact with the radio firmware to adjust client adapter settings and display information about the adapter.

ACU enables you to create configuratio n profiles for your clien t adapter and perform user-level diagnostics. Because ACU performs a variety of functions, it is documented by function throughout this manual. However, an overview of the utility is provided below to familiarize you with its interface.

ACM, which is accessible from an icon in the Windows system tray, provides a small subset of the features available through ACU. Specifically, it enables you to access status information about your client adapter and perform basic tasks. Chapter 8 pro vides detailed informati on and instructions on using ACM.

Note If your computer is runni ng Windows XP, you can c onfigure your cli ent adapt er throu gh the Windows

operating system instead of through ACU. Refer to Appendix E for information. However, ACU is recommended f or configu ring t he c lie nt ad ap ter.

Wireless Infrastructure with Workstations Accessing a Wired LAN

A microcellular network ca n be create d by placing two or mo re access po ints on a LAN . Figure 1-3 shows a microcellular networ k with workstations accessing a wired LAN through several access points.

This configuration is useful with portable or mobile stations because it allows them to be directly connected to the wired network even while moving from one microcell domain to another. This process is transparent, and the connection to the f ile serv er or host is maintained witho ut disruption . The mobile station stays connected to an access point as long as it can. However, once the transfer of data packets needs to be retried or beacon s are missed, the stati on automatically sear ches for and associates to another access point. This process is referred to as seamless roaming.

Site Requirements

This section discusses the site re quiremen ts for both infr astruc ture and cl ient devices.

For Infrastructure Devices

Because of differen ces i n comp one nt co nfigurat ion, p lac em ent , an d p hysi cal environmen t, every network application is a unique installation. Therefore, before you install any wireless infrastructure devices (such as access points, bridges, and base stations, which connect your client adapters to a wired LAN), a site survey must be performe d to determi ne the opti mum pla cement of t hese devices to maximize range, coverage, an d network pe rform ance. Appendix F, which is provided for people who are responsi ble f or condu ct ing a si te sur vey, explains how ACU’s site survey tool can be used to determine the best placement for infrastructure devices within a wireless network.

Note Infrastructure devices are installed and initially configured prior to client dev ices.

For Client Devices

Because the client adapter is a radio device, it is susceptible to RF obstructi ons and common sources of interference that can reduce throughput and range. Follow these guidelines to ensure the best possible performance:

• Install the client adapter in an area where large steel structures such as shelving units, bookcases,

and filing cabinets will not obstruct radio signals to and from the client adapter.

• Install the client adapter away from microwave ovens. Microwave ovens operate on the same

frequency as the client adapter and can cause signal interference.

Chapter 4 Using the Profile Manager

Overview of Profile Manager

ACU’s profile manager fea ture al lows you to c re at e an d m a nage up to 16 profiles (or saved configurations) fo r your client adapter. These profiles enable you to use your client adapter in different locations, each of which requires different configuration settings. For example, you may want to set up profiles for using your client adapter at the office, at home, and in public areas such as airports. Once the profiles are cr e ated, yo u c an e a sily swi tch b etwee n the m witho ut h aving to r e con figure your c li ent adapter each time you enter a new location.

Profiles are sto red in the pa rt of th e re gistr y reser v ed for th e cli ent adap ter driver and, therefore, are tied to radio type. C onsequ en tly, if you set up p rofiles fo r a 340 seri es PC c ard a nd lat er up gra de t o a 3 50 series PC card, all of the profiles will be lost. Similarly, all profiles are lost if you uninstall the client adapter’s software component s. To prevent your profiles from becoming lost, Cisco recommend s that you back up your profiles using the pro file manager’s import/export feature. See the “Importing and

Exporting Profiles” se ct ion o n page 4-9 for details.

Opening Profile Manager

To op en ACU’s profile manager, double-click t he Aironet Client Utility (ACU) icon o n y our d esk top or double-click My Computer > Control Panel > Aironet Client Utility to open ACU. Then click the Profile Manager icon or select Profile Manager from the Commands dro p-d own menu. T he Profile Manager screen appears (se e Figure 4-1).

Step 3 All the prof iles that you created are listed in the Available Profiles box. Highlight e ach one that you want

to include in auto profile selection and click the Add button. The profiles move to the Auto Selected Profiles box.

The following rules apply to auto profile selection:

• You must include at least two profiles in the Auto Selected Profiles Box.

• The profiles must specify an SSID; otherwise, they cannot be selected in the Available Profiles

box.

• Profiles cannot specify multiple SSIDs; otherwise, they cannot be selected in the Available

Profiles box.

• Each profile that is included in auto profile selection must have a unique SSID. For example,

if Profile A and Profile B both have “ABCD” as their SSID, only Profile A or Profile B can be included in auto profile selection.

Note If you ev er w ant to remo v e a prof ile f rom auto profile selection, highlight the profile in th e Auto

Selected Profiles box and click the Remove button. The profile moves to the Available Profiles box.

Selecting the Active Profile

Step 4 The first profile in the Auto Selec ted Profiles box has t h e hi gh est prior ity whil e t he l ast profile has t he

lowest priority. To c hange the order (and priority) of y our auto-selectable profiles, highlight the profile that you want to move and click the High Pri ority or Low Prior ity arrow to move the profile up or down, respectively.

When auto profile selection is enabled , the client adapter scans for an a vailable network. The profile with the highest priority and the same SSID as one of the found networks is the one that is used to connect to the network. If the co nnec tio n f ai ls, the client adapter tries th e next highest priority prof ile th at m at ches the SSID and so on.

Step 5 Click OK to save your changes.

Selecting the Active Profile

Follow the steps below to specify the profile that the client adapter is to use.

Note Because EAP-TLS, PEAP, and EAP-SIM authentication are enabled in the operating system and not in

ACU, you cannot switch between these authentication types simply by switching profiles in ACU. You can create a profile in ACU that uses host-based EAP, but you must enable the specific authentication type in Windows (provided Windows is using the Mi cr osoft 80 2.1X sup pli cant ). I n ad ditio n, Windows can be set for only one aut hentication typ e at a time; therefore, if you hav e more than one pro file in ACU that uses host-based EAP and you wan t to use another authenticat ion type, yo u must chang e authentication types in Windows after switching profiles in ACU.

Note You can u se ACM instea d of ACU’s Profile Manager to select the active profile. Refer to Chapter 8 for

instructions.

Step 1 Open ACU; click the Select Profile icon or select Select Profile from the Commands drop-down menu.

The Select Profile screen appears (see Figure 4-2).

Step 2 Select one of the following options:

• Use Selected Profile—This option enables you to select one profile for the client adapter to use. If

you choose this option, y ou also must sel ect t h e de sire d p rofile fr om t he d rop -down box. If the client adapter ca nnot as socia te to an access po int or lo ses ass ociatio n while us ing th e sele cted

profile, th e adapter does no t attempt to asso ciate usin g anoth er prof ile. To associate, you must selec t a different profile or select Use Auto Profile Selection.

Note If no profiles have been set for your client adapter, the Use Selected Profile drop-down box

is disabled but displays “Driver Advanced Tab Settings.”

Chapter 4 Using the Profile Manager

Modifying a Profile

• Use Auto Profile Selection—This option causes the client adapter’s driver to automatically select

a profile from the list of profiles that wer e set up to be inc luded in auto profile selecti on. If the client adapter loses association for more than 10 seconds (or for more than the time specified

by the LEAP authentication timeout value on the LEAP Settings screen if LEAP is enabled), the driver sw itches automatically to anothe r profile that is incl uded in auto prof ile selection. The adapte r will not switch prof ile s as long as it remains ass ociat ed or reas soci ates w ithin 10 seconds ( or wit hin the time specifi ed by the LEAP aut hentication timeo ut value). To force the client adapter to associate to a different access point, you must select a new profile using the Use Selected Profile option.

Note This option is available only if two or more profiles are included in auto profile selection.

Note Login scripts are n ot r elia ble i f you use auto pr ofile sele c tion w it h LEAP. If you LEAP

authenticate and achie v e full netwo rk connecti vity before or at the same time as y ou log into the computer , the login scrip ts will run. Ho we ver, if you LEAP authenticate and achiev e full network connectivity after you log into the computer, the login scripts will not run.

• Use Another Application to Conf igure My W ireless Set tings—This option enables an a pplication

other than ACU to conf igure the client adapter. Examples of such applications include Wi ndo ws XP and Boingo.

Note You must s el ect this option if you are configuring your card through Windows XP but want

to use ACU’s diagnostic tools. Refer to Appendix E for information on configuring your client adapter throu gh Windows XP.

Step 3 Click OK or Apply to save your selection. The client adapte r sta rts u sin g a p rofile ba sed on t he opt ion

Setting System Parameters

Power Save Mode Sets your client adapter to its optimum power consumpt ion settin g.

Options: CAM, Max PSP, or Fast PSP Default: CAM (Constantly Awake Mode)

Power Save Mode Description

CAM (Constantly Awake Mode)

Keeps the client adapter powered up continuously so there is little lag in message response time.

Consumes the most power but offers the highest throughput. Is r ecom me nded f or desktop computers a nd devices t hat use AC p o we r.

Max PSP (Max Power Savings)

Causes the access point to buffer incoming messages for the client adapter, which wakes up periodically and polls the access point to see if any buffered messages are waiting for it. The adapter can request each message an d t h en go bac k t o s le ep .

Conserves the most power but offers the lowest throughput. Is recomm ended for devices for which power consumption is the ultimate concern (such as small battery-powered devices).

Note When you set Max PSP mode and

close ACU, th e follo wing message appears the next tim e yo u o pe n ACU: “Maximum Power Save Mode will be temporarily disabl ed while you are running this application.” While ACU is open, Fast PSP mode is active. When you close ACU, the card returns to Max PSP mode.

Fast PSP (Power Save Mode)

Switches between PSP mode and CAM mode, depending on ne twork tra ffic. This mode switches to CAM when retrieving a large number of packets and switches back to PSP after the packets have been retrieved.

Is recommended when power consumption is a concern but you need greater throughput than tha t all owed by Max PSP.

Use Short Radio Hea ders Checking this check box sets you r c li ent a da pter t o use s hor t ra dio

headers. However, the adapter can use short radio headers only if the access point is also configured to support them and is using them. If any clients associated to an access point are using long headers, then all clients in that cell must also use long headers, even if both this client and the access point have short radio head ers enable d.

Short radio headers improve throu ghput per formanc e; long radio headers ensure compatibility with clients and access points that do not support short radio headers.

Default: Checked

Note This para me ter is available on ly fo r 2. 4-G Hz cl ient ad ap ters . Note This pa rameter is referr ed to as Preambles on th e ac cess po int

This parameter is available only in infrastructure mo de a nd is desi gn ed f or use rs w ho travel betw een countries and want their client adapte rs to associ ate to acc ess points in different regulatory domains.

Default: Unchecked

Note This para me ter is available on ly fo r 2. 4-G Hz cl ient ad ap ters . Note When World Mode is enabled, the client adapter is limited to

the maximum transmit power level allowed by the country of operation’s regulatory agency.

Scan For A Better Access Point

Checking this check box causes the client 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 5 0% are used, the

client begins monitoring the strength of the signal received from its associated acc es s p oint 2 0 se co nd s af ter be co ming associated. The m on ito ring c ontinue s once pe r se co nd. I f the client detects a signal strength reading below 50%, it scans for a better access point.

Range: 5 to 255 seconds; 0 to 7 5% si gnal streng th Defaults:Checked, 20 seconds, 50% signa l strength

Note The ability to specify the time and signal strength is available

Setting Network Security Parameters

This screen is d ifferen t from the other Proper ties screens in that it p resents se ver al security f eatures, ea ch of which involves a number of steps. In addition, the security features themselves are complex and need to be understood before they are implemented. Therefore, this section provides an overview of the security features as well as procedures for using them.

However , before you determine the appropriate security settings for your client adapter, you must decide how to set the Allow Asso ciation to Mixed Cells parameter , which ap pears at the bottom of the Network Security screen and is not associated to any of the security features. See the “Setting the Allow

Association to Mixed Cells Param eter” section below.

Setting the Allow Association to Mixed Cells Parameter

The Allow Association to Mixed Cells parameter indicates whether the client adapter can associate to an access point that allows both WEP and non-WEP associations. Follow the steps below to set this parameter.

Note This parameter is unavailable if the Wi-Fi Protected Acc ess (WPA) check box is checked.

Step 1 Perform one of the following:

• Check the Allow Association to Mixed Cells check box if the access point with which the client

adapter is to associate has WEP set to Optional and WEP is enabled on the client adapter. Otherwise, the client is unable to establish a connection with the access point.

• Uncheck the Allow A ssoci atio n to Mixed C ells c he ck b ox if the a cce ss poin t wi th w hi ch th e cl ien t

adapter is to associate does not have WEP set to Optional. This is the default setting.

Note For security reasons, Cisco recommends that WEP-enabled and WEP-disabled clients not be

allowed in the same cell because broadcast packets are sent unencrypted, even to clients running WEP.

Step 2 Perform one of the following:

• If you do not want to change any other paramete rs on the Network Se curit y screen, cl ick OK to

return to the Profile Manager screen; then click OK or Apply to save your changes

• If you want to change some of the othe r para me ters on the Networ k Secur ity scree n, g o to the next

section.

Overview of Security Featu res

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.

Chapter 5 Configuri ng the Client Adapter

Setting Network Security Parameters

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 authentica tion process. The informat ion in the “Static

WEP Keys” and “EAP (with Dynamic WEP Keys)” sections be low 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 dyna mic , are e ith er 40 o r 1 28 bits in len gth. 12 8-b it WE P keys offer a greater level of security than 40-bit WEP keys.

Note Refer to the “Additional WEP Key Security Features” section on page 5-28 for information on three

security features that ca n make your WEP keys even more secure.

Static WEP Keys

Each device (or profile) w ith in yo ur wi reless ne twork can be assign ed u p to fo ur stat ic WE P keys. If a device receives a packet that is not encrypted with the a ppropr iate 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.

Static WEP keys are write-only and temporary; therefore, they cannot be read back from the client adapter, and they are lost when power to the adapter is removed or the Windows device is rebooted. Although the keys are temporary, you do not need to re-enter them each time the client adapter is inserted or the Windows device is rebooted. Th is i s beca use th e keys are st ored (in an e ncry pt ed f orm at for security reasons) in the registry of the Windows device. When the driver loads and reads the client adapter’s registry parame ters, it also find s the s tat ic WE P keys, une ncryp ts t hem, a nd stor es them i n volatile memory on the adapter.

The Network Security screen enab les you to view the curre nt WEP key settings for the cl ient adapter and then to assign new WEP ke ys or ov erwr ite e xisting WEP ke ys as well as to enabl e or disab le static WEP. Refer to the “Using Static WEP” section on page 5-32 for instructions.

EAP (with Dynamic WEP Keys)

The new standard for wireless LAN secu rity, as defined by the Institute of Electri cal and E lectronic s Engineers (IEEE), is called 802.1X for 802.11, or simply 802.1X. An access point that supports 802.1X and its protocol, Extensi ble Auth entica tion Protoc ol (EAP) , acts as th e interfac e betwee n a wireless client and an authentication server, such as a Remote Authentication Dial-In User Service (RADIUS) server, to which the access point communicates over the wired network.

Two 802.1X authenticat ion typ es c an be se le cted in ACU for use w it h Windows operating system s:

• EAP-Cisco Wireless (or LEAP)—This authentication type is av ailable for W indo ws 98, 98 SE, NT,

2000, Me, and XP, as well as non-Windows systems. Support f or LEA P is provi ded n ot in the Windows operating system but in your client adapter’s firmware and the Cisco software that supports it. RADIUS servers that support LEAP include Cisco Secure ACS version 2.6 and greater, Cisco Access Registrar version 1.7 and greater, and Funk Software’s Steel-Belted RADIUS version

3.0 and greater. LEAP is enabled or disab led for a specif ic profi le through A CU, pro vided the LEAP security module

was selected during inst al lati on. A fte r LEA P i s enabl ed, a variety of c onfigurat ion op tio ns are available, including how and when a username and password are entered to begin the authentication process.

OL-1394-07

Chapter 5 Configuring the Client Adapter

Setting Network Security Parameters

The username and password are used by the client adapter to perform mutual authentication with the RADIUS server through the access point. The username and password are stored in the client adapter’s volatile memory; therefore, they are temporary and need to be re-entered whenever power is removed from the adapter, typically due to the client adapter being ejected or the system powering down.

Note If the LEAP security module was not selected during installation, the LEAP option is

unavailable in ACU. If you want to be able to enable and disable LEAP, you must run the installation program again and select LEAP.

• Host Based EAP—Selecting this option enables you to use any 802.1X authentication type for

which your operating system has support. For example, if your operating system uses the Microsoft

802.1X supplicant, it provides n ative support for EAP-TLS authe nticat ion and gener al suppor t for PEAP and EAP-SIM authentication.

Note T o use EAP-TLS, PEAP, or EAP-SIM authentication, you must install the Microsoft 802.1X

supplicant, A CU, and the PEAP or EA P-SIM secur ity module; conf igur e your cli ent adapter using ACU; enable the authentication type in Windows; and enable Network-EAP on the access point.

–

EAP-TLS—EAP-TLS is enabled or disabled through the operating system and uses a dynamic session-based WEP key, which is derived from the client adapter and RADIUS server, to encrypt data. Once enabled, a few configuration parameters must be set within the operating system.

RADIUS servers that su pport EA P-TLS auth en ticati on incl ude Cisco Se cure ACS version 3.0 or greater and Cisc o Acc ess Regi strar version 1. 8 o r gre ater.

Note EAP-TLS requires the use of a certificate. Refer to Microsoft’s documentation for

information on downloading and installing the certificate.

–

Protected EAP (or PEAP)—PEAP authentication is designed to support One-Time Password (OTP), Windo ws NT or 2000 domain, and LDAP user databases over a wireless LAN. It is based on EAP-TLS authenticati on but uses a password or PIN instea d of a client certificate for authentication. PEAP i s ena bl ed o r disab led t hrough t he ope rat ing syste m and u ses a dy nami c session-based WEP key, which is derived from the client adapter and RADIUS server, to encrypt data. If your network uses an OTP user database, PEAP 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 requires you to enter your username, password, and domain name in order to start the authentication process.

RADIUS servers that support PEA P aut henti cation inc lude Ci sco Secur e ACS version 3.1 or greater and Cisco A cc ess Registra r versio n 3.5 or g reater.

Note Windows XP Service Pack 1 and the Microsoft 802.1X supplic ant for Windows 2000

include Microsoft’s PEAP supplicant, which supports a Windows username and password only and does not interop er ate with Cisco’s PEAP supplicant. To use Cisco’s PEAP supplicant, install the I nstall W iza rd file after Windows XP Service P ack 1 or the Microsoft 802.1X suppl icant for Windows 2000. Otherwi se, Cisco ’s PEAP supplicant is overwritten by Microsoft’s PEAP supplicant.

EAP-SIM—EAP-SIM authentication is designed for use in public wireless LANs and requires clients equipped with PCSC-compliant smartcard readers. The EAP-SIM supplicant included in the Install Wizard file supports only Gemplus SIM+ cards; however, an updated supplicant is available that supports standard GSM-SIM cards as well as more recent versions of the EAP-SIM protocol. T he new suppl icant i s available for downloa d f rom t he ftpe ng FTP se rver at the following URL:

ftp://ftpeng.cisco.com/ftp/pwlan/eapsim/CiscoEapSim.dll

Please note that the abo v e req uire me nts are necess ary b ut not suf ficient to successfully perf orm EAP-SIM authentication. Typically, you are also required to enter into a service contract with a WLAN service provider, who must support EAP-SIM authentication in its network. Also, while your PCSC smartcard reader may be able to read standard GSM-SIM cards or chips, EAP-SIM authentication usu ally requir es your GSM ce ll phone ac count to be provisio ned for WLAN service by your service provider.

EAP-SIM is enabled or disabled through the operating system and uses a dynamic session-based WEP key, which is derived from the client adapter and RADIUS server, to encrypt data. EAP-SIM requires y ou to e nte r a use r veri fication c ode, or PIN, for communication with the SIM card. You can choose to have the PIN stored in you r compu ter or to be prom pted t o ent er it after a reboot or prior to every authent icatio n attempt .

RADIUS servers that suppor t E AP-SIM includ e Cisc o Ac cess Registrar vers ion 3 .0 or g reate r.

Note Because EAP-TLS, PEAP, and EAP-SIM au thenticatio n are en abled in the operatin g system

and not in A CU, y ou cann ot switc h be twee n these a ut henti cat ion types simply by switching profiles in ACU. You c an c rea te a pr ofile in ACU that uses host - bas ed E AP, but you must enable the spe cific a uthe nti cat ion type in Windows (provided Windows uses the Mi crosof t

802.1X supplicant). In additio n, Windows can be set for only one aut henti cation type at a time; therefore, if you have more than one profile in ACU that uses host-based EAP and you want to use another authe ntic at ion ty pe, yo u must chan ge authe nti cat ion typ es in Windows after switching profiles in ACU.

When you enable Network-EAP or EAP on you r acc ess point and co nfigure your clien t adapter for LEAP, EAP-TLS, PEAP, or EAP-SIM, authentication to the network occurs in the following sequence:

1. The client 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 RA DI US se rver is su cc e ssfu l.

2. Communicating through the access point, the client and RADIUS server complete the authentication

process, with the password (LEAP and PEAP), certificate (EAP-TLS), or internal key stored on the SIM card and in the servi ce provid er’s Authenticatio n Center (EAP- SIM) being the shared secr et for authentication. The password or internal key is never transmitted during the process.

3. If authentication is succ essful , the clie nt an d RADI US serv er der i v e a dyn amic, sessio n-base d WEP

key that is unique to the client.

4. The RADIUS server transmits the key to the acc ess poin t u sing a sec ure c hannel on the wir ed LAN.

5. For the length o f a session, or time per iod, the access point and the client use this key to encrypt or

decrypt all unicast packet s (and broa dcast packet s if the acc ess point is set up to do so) that travel between them.

Wi-Fi Protected Access (WPA)

Wi-Fi Protected Access (WPA) is a standards-based, int erope r able s ecu rity e nhanc eme nt t hat gre atly 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 aut hent ic ate d key m anage men t.

WPA supports t wo mutually exclusive key management types: WPA and WPA-Pr e-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 ar e installed on c omputer s running Windows 2000 or XP and running LEAP or h ost -base d EAP au then tic atio n c an b e used wit h WPA. Support for WPA is available in the software c ompon en t s inc lude d in I nst all Wizard version 1. 2 or gr ea ter. However, if you want to use host-based EAP authentication with WPA, you must install additional software with WPA support. The following WPA software is recommended for use with Cisco Aironet client adapters:

• Funk Odyssey Client supplica nt version 2. 2 ( for Windows 2000)

• Windows XP Service Pack 1 and Microsoft support patch 815485 (for Windows XP)

Note Meetinghouse AEGIS Client supplicant version 2.1 is also supported for use with Windows 2000

and XP; however, it was not tested with this client adapter software release.

Refer to the “Enabling LEAP” section on pa ge 5-35 for instructions on enabling LEAP with WPA or to the “Enabling Host-Based EAP” sect io n on page 5-39 for instructions on enabling EAP-TLS, PEAP, or EAP-SIM with WPA.

Note WPA must also be en abled on the access point. Acc ess points must use Cisco IOS Release 12.2(11)JA

or greater to enable WPA. Refer to the documentation fo r yo ur a cce ss point f or in str uctio n s on en a bli ng 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 greater.

Chapter 5 Configuri ng the Client Adapter

Setting Network Security Parameters

During normal operation, LEAP-enabled clients mutually authenticate with a new access point by performing a comp let e LE AP auth en tic ation , i ncl udin g c omm unic atio n w ith the m a in RA DIU S ser ver. 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 ways, depending on the software installed:

• If you are using ACU version 6.2 and client adapter firmware version 5.30.15 (which is included in

Install Wizard version 1.2), you need to enabl e fast roami ng in ACU. Refer to Step 10 in the

“Enabling LEAP” section for details.

• 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 i s enabl ed on the cl ient ad ap ter, it must al so be e nabl ed o n th e ac cess point.

Note Access points must use Cisco IOS Release 12.2(11)JA or greater to enable fast roaming. Refer to the

documentation for you r access point for instr uctions on en ablin g this fea ture.

Note If the Microsoft 802.1X supplicant is installed on your computer, you must disable one or two Windows

parameters in order for this f eature to operate co rrectly . Refer to St ep 13 in the “Enabling LEAP” section for details.

Reporting Access Points that Fail LEAP Authentication

Client adapter firmware version 5.02.20 or greater and the following acc ess point firmware versions support a feature that is designed to detect access points that fail LEAP authentication:

• 12.00T or great er ( 340, 3 50, a nd 12 00 se ries a cce ss p oint s)

• Cisco IOS Release 12.2(4)JA or greater (1100 series access points)

An access point running one of t hese firmware versio ns records a message in the system log whe n a client running firmware version 5.02.2 0 or greater di scovers and reports an other acc ess point in th e wireless network that has failed LEAP authentication.

The process takes place as follows:

1. A client with a LEAP profile attempts to associate to access point A.

2. Access point A does not ha ndle LE AP authentic ation suc cessfully, perhaps because the a ccess po int

does not understand LEAP or ca nnot com muni cate to a trust ed LEAP a uthent icati on server.

3. The client rec ords the M AC address for access point A and th e reason w hy the associa tion failed.

4. The client associates successfully to access point B.

5. The client sends the MAC address of access point A and the reason code for the failure to access

point B.

6. Access point B logs the failure in the system log.

Additional WEP Key Security Features

The three security features discussed in this section (MIC, TKIP, and broadcast key rotation) are designed to prevent sophistic ated a ttac ks o n you r w ire le ss networ k’s WEP keys. These features do not need to be enabled on the client adapter; they are supported automatically in the firmware and driver versions included in the Install Wizard file. However, they must be enabled on the access point.

Note Access point firmware version 11.10T or greater is required to enable these security features. Refer to

the documentation for your access point for instructions on enabling these security features.

Message Integrity Check (MIC)

MIC prevents bit-flip attacks on encrypted packets. During a bit-flip attack, an intruder intercepts an encrypted message, alters it slightly, and retransmits it, and the receiver accepts the retransmitted message as legitimate. The MIC adds a few bytes to each packet to make the packets tamper-proof.

The Status scre en ind icat es if MI C is be ing use d, and th e St atist ics sc reen provides MIC sta tis tics .

Note If you enable M IC o n the acc ess poi n t, y our cl ient ad ap ter ’s driver must support these features;

otherwise, the client cannot associate.

Temporal Key Integrity Pr otocol (TKIP)

This feature, also referred to as WEP key hashing, defends against an attack on WEP in which the intruder uses the init ialization vect or (IV) in en crypted p acket s to calculate the WEP ke y. TKIP removes the predictability that an intrud er relies o n to de termi ne th e WEP key by exp loitin g IVs. It pro tec ts both unicast and broadcast WEP keys.

Note If you enable TKIP on the access point, your client adapter’s firmware must support these features;

otherwise, the client cannot associate.

Note TKIP is automatically enabled whenever WPA is enabled, and it is disabled whenever WPA is disabled.

Broadcast Key Rotation

EAP authentication provides dynamic unicast WEP keys for client devices but uses static broadcast, or multicast, keys. When you enable broadcast WEP key rotation, the access point provides a dynamic broadcast WEP key and changes it at the interval you select. When you enable this feature, only wireless client devices using LEAP, EAP-TLS, PEAP, or EAP-SIM authentication can associate to the access point. Client devices u si ng st ati c WE P ( with op en or sh ar ed key aut hent ica tion) c annot assoc ia te.
