4-73SecurityHTTP Server: Shows if management access via HTTP is enabled.HTTP Server Port: Shows the TCP port used by the HTTP interface.Version: Shows the software version number.802.1X: Shows if IEEE 802.1X access control for wireless clients is enabled.AP Wireless Configuration – The AP Wireless Configuration tables display the radio and VAP interface settings listed below. Note that Interface Wireless A refers to the 802.11a radio and Interface Wireless G refers the 802.11b/g radio.VAP: Displays the VAP number.Radio Status: Displays if the radio is enabled or disabled for this VAP.SSID: The service set identifier for the VAP interface.Radio Channel: The radio channel through which the access point communicates with wireless clients.Radio Encryption: The key size used for data encryption.Radio Auth. Type: Shows the type of authentication used.Output Antenna: Displays which antenna/e are in use by the VAP.MAC: The physical layer address of the radio interface.Station StatusThe Station Status window shows the wireless clients currently associated with the access point.Figure 37 Station StatusThe Station Configuration page displays basic connection information for all associated stations as described below. Note that this page is automatically refreshed every five seconds. Station Address: The MAC address of the wireless client.Authenticated: Shows if the station has been authenticated. The two basic methods of authentication supported for 802.11 wireless networks are “open
4-74CHAPTER 4: SYSTEM CONFIGURATIONsystem” and “shared key.” Open-system authentication accepts any client attempting to connect to the access point without verifying its identity. The shared-key approach uses Wired Equivalent Privacy (WEP) to verify client identity by distributing a shared key to stations before attempting authentication.Associated: Shows if the station has been successfully associated with the access point. Once authentication is completed, stations can associate with the current access point, or reassociate with a new access point. The association procedure allows the wireless system to track the location of each mobile client, and ensure that frames destined for each client are forwarded to the appropriate access point.Forwarding Allowed: Shows if the station has passed 802.1X authentication and is now allowed to forward traffic to the access point.Key Type – Displays one of the following:• WEP Disabled – The client is not using Wired Equivalent Privacy (WEP) encryption keys.• Dynamic – The client is using Wi-Fi Protected Access (802.1X or pre-shared key mode) or using 802.1X authentication with dynamic keying.• Static – The client is using static WEP keys for encryption.Event LogsThe Event Logs window shows the log messages generated by the access point and stored in memory.Figure 38 Event LogsThe Event Logs table displays the following information:Log Time: The time the log message was generated.Event Level: The logging level associated with this message. For a description of the various levels, see “logging level” on page 4-46.Event Message: The content of the log message.Error Messages – An example of a logged error message is: “Station Failed to authenticate (unsupported algorithm).”This message may be caused by any of the following conditions:
4-75SecurityAccess point was set to “Open Authentication”, but a client sent an authentication request frame with a “Shared key.”Access point was set to “Shared Key Authentication,” but a client sent an authentication frame for “Open System.”WEP keys do not match: When the access point uses “Shared Key Authentication,” but the key used by client and access point are not the same, the frame will be decrypted incorrectly, using the wrong algorithm and sequence number.

5-775COMMAND LINE INTERFACEUSING THE COMMAND LINE INTERFACEACCESSING THE CLIWhen accessing the management interface for the over a direct connection to the console port, or via a Telnet connection, the access point can be managed by entering command keywords and parameters at the prompt. Using the access point’s command-line interface (CLI) is very similar to entering commands on a UNIX system.CONSOLE CONNECTIONTo access the access point through the console port, perform these steps:1. At the console prompt, enter the user name and password. (The default user name is “admin” and the default password is “password”) When the user name is entered, the CLI displays the “Enterprise AP#” prompt. 2. Enter the necessary commands to complete your desired tasks. 3. When finished, exit the session with the “exit” command.After connecting to the system through the console port, the login screen displays:Username: adminPassword: Enterprise AP#NOTE: Command examples shown later in this chapter abbreviate the console prompt to “AP” for simplicity.
5-78CHAPTER 5: COMMAND LINE INTERFACETelnet ConnectionTelnet operates over the IP transport protocol. In this environment, your management station and any network device you want to manage over the network must have a valid IP address. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. Each address consists of a network portion and host portion. For example, if the access point cannot acquire an IP address from a DHCP server, the default IP address used by the access point, 168.254.2.1, consists of a network portion (168.254.2) and a host portion (1).To access the access point through a Telnet session, you must first set the IP address for the access point, and set the default gateway if you are managing the access point from a different IP subnet. For example:If your corporate network is connected to another network outside your office or to the Internet, you need to apply for a registered IP address. However, if you are attached to an isolated network, then you can use any IP address that matches the network segment to which you are attached.After you configure the access point with an IP address, you can open a Telnet session by performing these steps.1. From the remote host, enter the Telnet command and the IP address of the device you want to access. 2. At the prompt, enter the user name and system password. The CLI will display the “Enterprise AP#” prompt to show that you are using executive access mode (i.e., Exec). 3. Enter the necessary commands to complete your desired tasks. 4. When finished, exit the session with the “quit” or “exit” command. After entering the Telnet command, the login screen displays:Enterprise AP#configureEnterprise AP(config)#interface ethernetEnterprise AP(if-ethernet)#ip address 10.1.0.1 255.255.255.0 10.1.0.254Enterprise AP(if-ethernet)#Username: adminPassword: Enterprise AP#NOTE: You can open up to four sessions to the device via Telnet.
5-79Using the Command Line InterfaceENTERING COMMANDSThis section describes how to enter CLI commands.Keywords and ArgumentsA CLI command is a series of keywords and arguments. Keywords identify a command, and arguments specify configuration parameters. For example, in the command “show interfaces ethernet,” show and interfaces are keywords, and ethernet is an argument that specifies the interface type.You can enter commands as follows:• To enter a simple command, enter the command keyword. • To enter commands that require parameters, enter the required parameters after the command keyword. For example, to set a password for the administrator, enter:Enterprise AP(config)#username smithMinimum AbbreviationThe CLI will accept a minimum number of characters that uniquely identify a command. For example, the command “configure” can be entered as con. If an entry is ambiguous, the system will prompt for further input.Command CompletionIf you terminate input with a Tab key, the CLI will print the remaining characters of a partial keyword up to the point of ambiguity. In the “configure” example, typing con followed by a tab will result in printing the command up to “configure.”Getting Help on CommandsYou can display a brief description of the help system by entering the help command. You can also display command syntax by following a command with the “?” character to list keywords or parameters.
5-80CHAPTER 5: COMMAND LINE INTERFACEShowing CommandsIf you enter a “?” at the command prompt, the system will display the first level of keywords for the current configuration mode (Exec, Global Configuration, or Interface). You can also display a list of valid keywords for a specific command. For example, the command “show ?” displays a list of possible show commands:The command “show interface ?” will display the following information:Partial Keyword LookupIf you terminate a partial keyword with a question mark, alternatives that match the initial letters are provided. (Remember not to leave a space between the command and question mark.) For example “s?” shows all the keywords starting with “s.”Enterprise AP#show ?

5-81Using the Command Line InterfaceNegating the Effect of CommandsFor many configuration commands you can enter the prefix keyword “no” to cancel the effect of a command or reset the configuration to the default value. For example, the logging command will log system messages to a host server. To disable logging, specify the no logging command. This guide describes the negation effect for all applicable commands.Using Command HistoryThe CLI maintains a history of commands that have been entered. You can scroll back through the history of commands by pressing the up arrow key. Any command displayed in the history list can be executed again, or first modified and then executed. Using the show history command displays a longer list of recently executed commands. Understanding Command ModesThe command set is divided into Exec and Configuration classes. Exec commands generally display information on system status or clear statistical counters. Configuration commands, on the other hand, modify interface parameters or enable certain functions. These classes are further divided into different modes. Available commands depend on the selected mode. You can always enter a question mark “?” at the prompt to display a list of the commands available for the current mode. The command classes and associated modes are displayed in the following table:Table 7 Command ModesExec CommandsWhen you open a new console session on an access point, the system enters Exec command mode. Only a limited number of the commands are available in this mode. You can access all other commands only from the configuration mode. To access Exec mode, open a new console session with the user name “admin.” The command prompt displays as “Enterprise AP#” for Exec mode. Class ModeExec PrivilegedConfiguration GlobalInterface-ethernetInterface-wirelessInterface-wireless-vapUsername: adminPassword: [system login password]Enterprise AP#
5-82CHAPTER 5: COMMAND LINE INTERFACEConfiguration CommandsConfiguration commands are used to modify access point settings. These commands modify the running configuration and are saved in memory. The configuration commands are organized into four different modes:• Global Configuration (GC) - These commands modify the system level configuration, and include commands such as username and password. • Interface-Ethernet Configuration (IC-E) - These commands modify the Ethernet port configuration, and include command such as dns and ip.• Interface-Wireless Configuration (IC-W) - These commands modify the wireless port configuration of global parameters for the radio, and include commands such as channel and transmit-power.• Interface-Wireless Virtual Access Point Configuration (IC-W-VAP) - These commands modify the wireless port configuration for each VAP, and include commands such as ssid and authentication.To enter the Global Configuration mode, enter the command configure in Exec mode. The system prompt will change to “Enterprise AP(config)#” which gives you access privilege to all Global Configuration commands.To enter Interface mode, you must enter the “interface ethernet,” or “interface wireless a,” or “interface wireless g” command while in Global Configuration mode. The system prompt will change to “Enterprise AP(if-ethernet)#,” or Enterprise AP(if-wireless)” indicating that you have access privileges to the associated commands. You can use the end command to return to the Exec mode.Command Line ProcessingCommands are not case sensitive. You can abbreviate commands and parameters as long as they contain enough letters to differentiate them from any other currently available commands or parameters. You can use the Tab key to complete partial commands, or enter a partial command followed by the “?” character to display a list of possible matches. You can also use the following editing keystrokes for command-line processing:Enterprise AP#configureEnterprise AP(config)#Enterprise AP(config)#interface ethernetEnterprise AP(if-ethernet)#

Use the no form to disable this function.Syntax [no] web-redirectDefault Setting DisabledCommand Mode Global ConfigurationCommand Usage • The web redirect feature is used to support billing for a public access wireless network. After successful association to an access point, a client is “redirected” to an access point login web page as soon as Internet access is attempted. The client is then authenticated by entering a user name and password on the web page. This process allows controlled access for clients without requiring 802.1X or MAC authentication.• Web redirect requires a RADIUS server on the wired network with configured user names and passwords for authentication. The RADIUS server details must also be configured on the access point. (See “show bootfile” on page 140.)•Use the show system command to display the current web redirect status.Example Enterprise AP(config)#web-redirectEnterprise AP(config)#
5-99Using the Command Line InterfaceAPmgmtIPThis command specifies the client IP addresses that are allowed management access to the access point through various protocols.SyntaxAPmgmtIP <multiple IP_address subnet_mask | single IP_address | any> •multiple - Adds IP addresses within a specifiable range to the SNMP, web and Telnet groups.•single - Adds an IP address to the SNMP, web and Telnet groups.•any - Allows any IP address access through SNMP, web and Telnet groups.•IP_address - Adds IP addresses to the SNMP, web and Telnet groups.•subnet_mask - Specifies a range of IP addresses allowed management access.Default SettingAll addressesCommand ModeGlobal ConfigurationCommand Usage• If anyone tries to access a management interface on the access point from an invalid address, the unit will reject the connection, enter an event message in the system log, and send a trap message to the trap manager.• IP address can be configured for SNMP, web and Telnet access respectively. Each of these groups can include up to five different sets of addresses, either individual addresses or address ranges.• When entering addresses for the same group (i.e., SNMP, web or Telnet), the access point will not accept overlapping address ranges. When entering addresses for different groups, the access point will accept overlapping address ranges.• You cannot delete an individual address from a specified range. You must delete the entire range, and reenter the addresses.• You can delete an address range just by specifying the start address, or by specifying both the start address and end address.NOTE: Secure Web (HTTPS) connections are not affected by the UI Management or IP Management settings.

5-118CHAPTER 5: COMMAND LINE INTERFACEDHCP Relay CommandsDynamic Host Configuration Protocol (DHCP) can dynamically allocate an IP address and other configuration information to network clients that broadcast a request. To receive the broadcast request, the DHCP server would normally have to be on the same subnet as the client. However, when the access point’s DHCP relay agent is enabled, received client requests can be forwarded directly by the access point to a known DHCP server on another subnet. Responses from the DHCP server are returned to the access point, which then broadcasts them back to clients.Tabl e 15 DHCP Relay Commandsdhcp-relay enableThis command enables the access point’s DHCP relay agent. Use the no form to disable the agent.Syntax[no] dhcp-relay enableDefault Setting DisabledCommand Mode Global ConfigurationCommand Usage • For the DHCP relay agent to function, the primary DHCP server must be configured using the dhcp-relay primary command. A secondary DHCP server does not need to be configured, but it is recommended.• If there is no response from the primary DHCP server, and a secondary server has been configured, the agent will then attempt to send DHCP requests to the secondary server.Example Command Function Mode Pagedhcp-relay enable Enables the DHCP relay agent GC 5-118dhcp-relay Sets the primary and secondary DHCP server addressGC 5-119show dhcp-relay Shows current DHCP relay configuration settingsExec 5-119Enterprise AP(config)#dhcp-relay enableEnterprise AP(config)#

You should therefore configure the engine ID with the snmp-server engine-id command before using this configuration command.• The access point enables SNMP v3 users to be assigned to three pre-defined groups. Other groups cannot be defined. The available groups are:- RO - A read-only group using no authentication and no data encryption. Users in this group use no security, either authentication or encryption, in SNMP messages they send to the agent. This is the same as SNMP v1 or SNMP v2c.- RWAuth - A read/write group using authentication, but no data encryption. Users in this group send SNMP messages that use an MD5 key/password for authentication, but not a DES key/password for encryption.- RWPriv - A read/write group using authentication and data encryption. Users in this group send SNMP messages that use an MD5 key/password for authentication and a DES key/password for encryption. Both the MD5 and DES key/passwords must be defined.• The command prompts for the following information to configure an SNMP v3 user:-user-name - A user-defined string for the SNMP user. (32 characters maximum)

5-161Using the Command Line Interfacebridge role (WDS)This command selects the bridge operation mode for the radio interface.Syntaxbridge role <ap | repeater | bridge | root-bridge >•ap - Operates only as an access point for wireless clients.•repeater - Operates as a wireless repeater, extending the range for remote wireless clients and connecting them to the root bridge. The “Parent” link to the root bridge must be configured. In this mode, traffic is not forwarded to the Ethernet port from the radio interface.•bridge - Operates as a bridge to other access points also in bridge mode.•root-bridge - Operates as the root bridge in the wireless bridge network.Default Setting APCommand Mode Interface Configuration (Wireless)Command Usage • When the bridge role is set to “repeater,” the “Parent” link to the root bridge must be configured (see “bridge-link parent” on page 162). When the access point is operating in this mode, traffic is not forwarded to the Ethernet port from the radio interface.• Up to four WDS bridge links (MAC addresses) per radio interface can be specified for each unit in the wireless bridge network. One unit only must be configured as the “root bridge” in the wireless network. The root bridge is the unit connected to the main core of the wired LAN. Other bridges need to specify one “Parent” link to the root bridge or to a bridge connected to the root bridge. The other seven WDS links are available as “Child” links to other bridges.• The bridge link on the radio interface always uses the default VAP interface. In any bridge mode, VAP interfaces 1 to 7 are not available for use.Example Enterprise AP(if-wireless a)#bridge role root-bridgeEnterprise AP(if-wireless a)#

5-169Using the Command Line InterfaceDefault Setting 15 secondsCommand Mode Global ConfigurationCommand Usage This command sets the maximum time (in seconds) the root device will wait before changing states (i.e., discarding to learning to forwarding). This delay is required because every device must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to the discarding state; otherwise, temporary data loops might result.Example bridge stp hello-timeUse this command to configure the spanning tree bridge hello time globally for the wireless bridge. Use the no form to restore the default.Syntax bridge stp hello-time <time>no bridge stp hello-timetime - Time in seconds. (Range: 1-10 seconds). The maximum value is the lower of 10 or [(max-age / 2) -1].

All device ports (except for designated ports) should receive configuration messages at regular intervals. Any port that ages out STP information (provided in the last configuration message) becomes the designated port for the attached LAN. If it is a root port, a new root port is selected from among the device ports attached to the network.Example bridge stp priorityUse this command to configure the spanning tree priority globally for the wireless bridge. Use the no form to restore the default.Syntax bridge stp priority<priority>no bridge stp prioritypriority - Priority of the bridge.

5-171Using the Command Line InterfaceDefault Setting 32768Command Mode Global ConfigurationCommand Usage Bridge priority is used in selecting the root device, root port, and designated port. The device with the highest priority becomes the STP root device. However, if all devices have the same priority, the device with the lowest MAC address will then become the root device. Example bridge-link path-costUse this command to configure the spanning tree path cost for the specified port.Syntax bridge-link path-cost <index> <cost> •index - Specifies the bridge link number on the wireless bridge. (Range: 1-6 required on wireless interface only)•cost - The path cost for the port. (Range: 1-65535)Default Setting 19Command Mode Interface ConfigurationCommand Usage • This command is used by the Spanning Tree Protocol to determine the best path between devices. Therefore, lower values should be assigned to ports attached to faster media, and higher values assigned to ports with slower media. • Path cost takes precedence over port priority.Example Enterprise AP(config)#bridge stp-bridge priority 40000Enterprise AP(config)#Enterprise AP(if-wireless a)#bridge-link path-cost 1 50Enterprise AP(if-wireless a)#

(Range: 1-6 required on wireless interface only)•priority - The priority for a port. (Range: 1-255)Default Setting 128Command Mode Interface ConfigurationCommand Usage • This command defines the priority for the use of a port in the Spanning Tree Protocol. If the path cost for all ports on a wireless bridge are the same, the port with the highest priority (that is, lowest value) will be configured as an active link in the spanning tree. • Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be enabled.Example Related Commandsbridge-link path-cost (5-171)show bridge stpThis command displays aging time and spanning tree settings for the Ethernet and wireless interfaces.Syntaxshow bridge stpCommand ModeExecEnterprise AP(if-wireless a)#bridge-link port-priority 1 64Enterprise AP(if-wireless a)#

But to support the maximum number of users in an area, you must keep the power as low as possible. Power selection is not just a trade off between coverage area and maximum supported clients. You also have to ensure that high strength signals do not interfere with the operation of other radio devices in your area.Example radio-modeThis command forces the operating mode for the 802.11g wireless interface.Syntaxradio-mode <b | g | b+g>•b - b-only mode: Both 802.11b and 802.11g clients can communicate with the access point, but 802.11g clients can only transfer data at 802.11b standard rates (up to 11 Mbps).•g - g-only mode: Only 802.11g clients can communicate with the access point (up to 54 Mbps).•b+g - b & g mixed mode: Both 802.11b and 802.11g clients can communicate with the access point (up to 54 Mbps).Enterprise AP(if-wireless g)#transmit-power halfEnterprise AP(if-wireless g)#

Select this method when the Antenna ID is set to “Default Antenna” to use the access point's integrated antennas. The access point does not support external diversity antennas.•left - The radio only uses the antenna on the left side (the side farthest from the access point LEDs). The access point does not support an external antenna connection on its left antenna. Therefore, this method is not valid for the access point.•right - The radio only uses the antenna on the right side (the side closest to the access point LEDs).

5-190CHAPTER 5: COMMAND LINE INTERFACEdtim-period This command configures the rate at which stations in sleep mode must wake up to receive broadcast/multicast transmissions. Syntaxdtim-period <interval>interval - Interval between the beacon frames that transmit broadcast or multicast traffic. (Range: 1-255 beacon frames)Default Setting 1Command Mode Interface Configuration (Wireless)Command Usage • The Delivery Traffic Indication Map (DTIM) packet interval value indicates how often the MAC layer forwards broadcast/multicast traffic. This parameter is necessary to wake up stations that are using Power Save mode.• The DTIM is the interval between two synchronous frames with broadcast/multicast information. The default value of 2 indicates that the access point will save all broadcast/multicast frames for the Basic Service Set (BSS) and forward them after every second beacon.• Using smaller DTIM intervals delivers broadcast/multicast frames in a more timely manner, causing stations in Power Save mode to wake up more often and drain power faster. Using higher DTIM values reduces the power used by stations in Power Save mode, but delays the transmission of broadcast/multicast frames.ExampleEnterprise AP(if-wireless g)#dtim-period 100Enterprise AP(if-wireless g)#
5-191Using the Command Line Interfacefragmentation-length This command configures the minimum packet size that can be fragmented when passing through the access point. Syntaxfragmentation-length <length>length - Minimum packet size for which fragmentation is allowed. (Range: 256-2346 bytes)Default Setting 2346Command Mode Interface Configuration (Wireless)Command Usage • If the packet size is smaller than the preset Fragment size, the packet will not be segmented.• Fragmentation of the PDUs (Package Data Unit) can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size. If there is significant interference present, or collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will speed up the retransmission of smaller frames. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames.Examplerts-thresholdThis command sets the packet size threshold at which a Request to Send (RTS) signal must be sent to the receiving station prior to the sending station starting communications.Syntaxrts-threshold <threshold>threshold - Threshold packet size for which to send an RTS. (Range: 0-2347 bytes)Enterprise AP(if-wireless g)#fragmentation-length 512Enterprise AP(if-wireless g)#
5-192CHAPTER 5: COMMAND LINE INTERFACEDefault Setting 2347Command Mode Interface Configuration (Wireless)Command Usage • If the threshold is set to 0, the access point always sends RTS signals. If set to 2347, the access point never sends RTS signals. If set to any other value, and the packet size equals or exceeds the RTS threshold, the RTS/CTS (Request to Send / Clear to Send) mechanism will be enabled.• The access point sends RTS frames to a receiving station to negotiate the sending of a data frame. After receiving an RTS frame, the station sends a CTS frame to notify the sending station that it can start sending data. • Access points contending for the wireless medium may not be aware of each other. The RTS/CTS mechanism can solve this “Hidden Node” problem.Examplesuper-a This command enables Atheros proprietary Super A performance enhancements.

Therefore, avoid frequent scanning or scans of a long duration unless there is a reason to believe that more intensive scanning is required to find a rogue AP.• A “rogue AP” is either an access point that is not authorized to participate in the wireless network, or an access point that does not have the correct security configuration. Rogue access points can be identified by unknown BSSID (MAC address) or SSID configuration. A database of nearby access points should therefore be maintained on a RADIUS server, allowing any rogue APs to be identified (see “rogue-ap authenticate” on page 203).

With authentication enabled and a configure RADIUS server, the access point checks the MAC address/Basic Service Set Identifier (BSSID) of each access point that it finds against a RADIUS server to determine whether the access point is allowed. With authentication disabled, the access point can identify its neighboring access points only; it cannot identify whether the access points are allowed or are rogues. If you enable authentication, you should also configure a RADIUS server for this access point (see “RADIUS” on page 20).Example Enterprise AP(if-wireless g)#rogue-ap enableconfigure either syslog or trap or both to receive the rogue APs detected.Enterprise AP(if-wireless g)#Enterprise AP(if-wireless g)#rogue-ap authenticateEnterprise AP(if-wireless g)#

5-208CHAPTER 5: COMMAND LINE INTERFACE• To use WEP shared-key authentication, set the authentication type to “shared-key” and define at least one static WEP key with the key command. Encryption is automatically enabled by the command.• To use WEP encryption only (no authentication), set the authentication type to “open-system.” Then enable WEP with the encryption command, and define at least one static WEP key with the key command.• When any WPA or WPA2 option is selected, clients are authenticated using 802.1X via a RADIUS server. Each client must be WPA-enabled or support 802.1X client software. The 802.1X settings (see “802.1X Authentication” on page 146) and RADIUS server details (see “RADIUS Client” on page 140) must be configured on the access point. A RADIUS server must also be configured and be available in the wired network.• If a WPA/WPA2 mode that operates over 802.1X is selected (WPA, WPA2, WPA-WPA2-mixed, or WPA-WPA2-PSK-mixed), the 802.1X settings (see “802.1X Authentication” on page 146) and RADIUS server details (see “RADIUS Client” on page 140) must be configured. Be sure you have also configured a RADIUS server on the network before enabling authentication. Also, note that each client has to be WPA-enabled or support 802.1X client software. A RADIUS server must also be configured and be available in the wired network.• If a WPA/WPA2 Pre-shared Key mode is selected (WPA-PSK, WPA2-PSK or WPA-WPA2-PSK-mixed), the key must first be generated and distributed to all wireless clients before they can successfully associate with the access point. Use the wpa-preshared-key command to configure the key (see “key” on page 210 and “transmit-key” on page 211). • WPA2 defines a transitional mode of operation for networks moving from WPA security to WPA2. WPA2 Mixed Mode allows both WPA and WPA2 clients to associate to a common VAP interface. When the encryption cipher suite is set to TKIP, the unicast encryption cipher (TKIP or AES-CCMP) is negotiated for each client. The access point advertises it’s supported encryption ciphers in beacon frames and probe responses. WPA and WPA2 clients select the cipher they support and return the choice in the association request to the access point. For mixed-mode operation, the cipher used for broadcast frames is always TKIP. WEP encryption is not allowed.• The “required” option places the VAP into TKIP only mode. The “supported” option places the VAP into TKIP+AES+WEP mode. The “required” mode is used in WPA-only environments. • The “supported” mode can be used for mixed environments with legacy WPA products, specifically WEP. (For example, WPA+WEP. The WPA2+WEP environment is not available because WPA2 does not support

Other keys can be used for decryption of data from clients.• When using IEEE 802.1X, the access point uses a dynamic key to encrypt unicast and broadcast messages to 802.1X-enabled clients. However, because the access point sends the keys during the 802.1X authentication process, these keys do not have to appear in the client’s key list.• In a mixed-mode environment with clients using static and dynamic keys, select transmit key index 2, 3, or 4. The access point uses transmit key index 1 for the generation of dynamic keys.Example Enterprise AP(if-wireless g)#key 1 64 hex 1234512345Enterprise AP(if-wireless g)#key 2 128 ascii asdeipadjsipdEnterprise AP(if-wireless g)#key 3 64 hex 12345123451234512345123456Enterprise AP(if-wireless g)#Enterprise AP(if-wireless g: VAP[0])#transmit-key 2Enterprise AP(if-wireless g)#
5-212CHAPTER 5: COMMAND LINE INTERFACEcipher-suite This command defines the cipher algorithm used to encrypt the global key for broadcast and multicast traffic when using Wi-Fi Protected Access (WPA) security. Syntaxcipher-suite <aes-ccmp | tkip | wep>•aes-ccmp - Use AES-CCMP encryption for the unicast and multicast cipher.•tkip - Use TKIP encryption for the multicast cipher. TKIP or AES-CCMP can be used for the unicast cipher depending on the capability of the client. •wep - Use WEP encryption for the multicast cipher. TKIP or AES-CCMP can be used for the unicast cipher depending on the capability of the client. Default Setting wepCommand Mode Interface Configuration (Wireless-VAP)Command Usage • WPA enables the access point to support different unicast encryption keys for each client. However, the global encryption key for multicast and broadcast traffic must be the same for all clients.• If any clients supported by the access point are not WPA enabled, the cipher-suite algorithm must be set to WEP.• WEP is the first generation security protocol used to encrypt data crossing the wireless medium using a fairly short key. Communicating devices must use the same WEP key to encrypt and decrypt radio signals. WEP has many security flaws, and is not recommended for transmitting highly sensitive data.• TKIP provides data encryption enhancements including per-packet key hashing (i.e., changing the encryption key on each packet), a message integrity check, an extended initialization vector with sequencing rules, and a re-keying mechanism. Select TKIP if there are clients in the network that are not WPA2 compliant.• TKIP defends against attacks on WEP in which the unencrypted initialization vector in encrypted packets is used to calculate the WEP key. TKIP changes the encryption key on each packet, and rotates not just the unicast keys, but the broadcast keys as well. TKIP is a replacement for WEP that removes the predictability that intruders relied on to determine the WEP key.
5-213Using the Command Line Interface• AES-CCMP (Advanced Encryption Standard Counter-Mode/CBCMAC Protocol): WPA2 is backward compatible with WPA, including the same 802.1X and PSK modes of operation and support for TKIP encryption. The main enhancement is its use of AES Counter-Mode encryption with Cipher Block Chaining Message Authentication Code (CBC-MAC) for message integrity. The AES Counter-Mode/CBCMAC Protocol (AES-CCMP) provides extremely robust data confidentiality using a 128-bit key. The AES-CCMP encryption cipher is specified as a standard requirement for WPA2. However, the computational intensive operations of AES-CCMP requires hardware support on client devices. Therefore to implement WPA2 in the network, wireless clients must be upgraded to WPA2-compliant hardware.Example mic_mode This command specifies how to calculate the Message Integrity Check (MIC). Syntaxmic_mode <hardware | software>•hardware - Uses hardware to calculate the MIC.•software - Uses software to calculate the MIC.Default Setting softwareCommand Mode Interface Configuration (Wireless)Command Usage • The Michael Integrity Check (MIC) is part of the Temporal Key Integrity Protocol (TKIP) encryption used in Wi-Fi Protected Access (WPA) security. The MIC calculation is performed in the access point for each transmitted packet and this can impact throughput and performance. The access point supports a choice of hardware or software for MIC calculation. The performance of the access point can be improved by selecting the best method for the specific deployment. • Using the “hardware” option provides best performance when the number of supported clients is less than 27. Enterprise AP(if-wireless g: VAP[0])#cipher-suite TKIPEnterprise AP(if-wireless g)#
5-214CHAPTER 5: COMMAND LINE INTERFACE• Using the “software” option provides the best performance for a large number of clients on one radio interface. Throughput may be reduced when both 802.11a and 802.11g interfaces are supporting a high number of clients simultaneously.Example wpa-pre-shared-key This command defines a Wi-Fi Protected Access (WPA/WPA2) Pre-shared-key.Syntaxwpa-pre-shared-key <hex | passphrase-key> <value>•hex - Specifies hexadecimal digits as the key input format.•passphrase-key - Specifies an ASCII pass-phrase string as the key input format.•value - The key string. For ASCII input, specify a string between 8 and 63 characters. For HEX input, specify exactly 64 digits.Command Mode Interface Configuration (Wireless-VAP)Command Usage • To support WPA or WPA2 for client authentication, use the auth command to specify the authentication type, and use the wpa-preshared-key command to specify one static key.• If WPA or WPA2 is used with pre-shared-key mode, all wireless clients must be configured with the same pre-shared key to communicate with the access point’s VAP interface.Example Related Commandsauth (5-207)Enterprise AP(if-wireless a)#mic_mode hardwareEnterprise AP(if-wireless g)#Enterprise AP(if-wireless g: VAP[0])#wpa-pre-shared-key ASCII agoodsecretEnterprise AP(if-wireless g)#
5-215Using the Command Line Interfacepmksa-lifetime This command sets the time for aging out cached WPA2 Pairwise Master Key Security Association (PMKSA) information for fast roaming.Syntaxpmksa-lifetime <minutes>minutes - The time for aging out PMKSA information. (Range: 0 - 14400 minutes)Default Setting 720 minutesCommand Mode Interface Configuration (Wireless-VAP)Command Usage • WPA2 provides fast roaming for authenticated clients by retaining keys and other security information in a cache, so that if a client roams away from an access point and then returns reauthentication is not required. • When a WPA2 client is first authenticated, it receives a Pairwise Master Key (PMK) that is used to generate other keys for unicast data encryption. This key and other client information form a Security Association that the access point names and holds in a cache. The lifetime of this security association can be configured with this command. When the lifetime expires, the client security association and keys are deleted from the cache. If the client returns to the access point, it requires full reauthentication.• The access point can store up to 256 entries in the PMKSA cache. Example pre-authentication This command enables WPA2 pre-authentication for fast secure roaming.Syntaxpre-authentication <enable | disable>•enable - Enables pre-authentication for the VAP interface. •disable - Disables pre-authentication for the VAP interface.Enterprise AP(if-wireless g: VAP[0])#wpa-pre-shared-key ASCII agoodsecretEnterprise AP(if-wireless g: VAP[0])#
5-216CHAPTER 5: COMMAND LINE INTERFACEDefault Setting DisabledCommand Mode Interface Configuration (Wireless-VAP)Command Usage • Each time a client roams to another access point it has to be fully re-authenticated. This authentication process is time consuming and can disrupt applications running over the network. WPA2 includes a mechanism, known as pre-authentication, that allows clients to roam to a new access point and be quickly associated. The first time a client is authenticated to a wireless network it has to be fully authenticated. When the client is about to roam to another access point in the network, the access point sends pre-authentication messages to the new access point that include the client’s security association information. Then when the client sends an association request to the new access point the client is known to be already authenticated, so it proceeds directly to key exchange and association.• To support pre-authentication, both clients and access points in the network must be WPA2 enabled.• Pre-authentication requires all access points in the network to be on the same IP subnet.Example Enterprise AP(if-wireless g: VAP[0])#wpa-pre-shared-key ASCII agoodsecretEnterprise AP(if-wireless g: VAP[0])#
5-217Using the Command Line InterfaceLink Integrity CommandsThe access point provides a link integrity feature that can be used to ensure that wireless clients are connected to resources on the wired network. The access point does this by periodically sending Ping messages to a host device in the wired Ethernet network. If the access point detects that the connection to the host has failed, it disables the radio interfaces, forcing clients to find and associate with another access point. When the connection to the host is restored, the access point re-enables the radio interfaces.Tabl e 28 Link Integrity Commandslink-integrity ping-detectThis command enables link integrity detection.

This command is used to enable or disable 802.11f handover signaling between different access points, especially in a multi-vendor environment.ExampleVLAN CommandsThe access point can enable the support of VLAN-tagged traffic passing between wireless clients and the wired network. Up to 64 VLAN IDs can be mapped to specific wireless clients, allowing users to remain within the same VLAN as they move around a campus site.When VLAN is enabled on the access point, a VLAN ID (a number between 1 and 4094) can be assigned to each client after successful authentication using IEEE 802.1X and a central RADIUS server. The user VLAN IDs must be configured on the RADIUS server for each user authorized to access the network. If a user does not have a configured VLAN ID, the access point assigns the user to its own configured native VLAN ID.The VLAN commands supported by the access point are listed below.Tabl e 29 VLAN CommandsEnterprise AP(config)#iappEnterprise AP(config)#NOTE: When VLANs are enabled, the access point’s Ethernet port drops all received traffic that does not include a VLAN tag.

Using WMM, the access point is able to prioritize traffic and optimize performance when multiple applications compete for wireless network bandwidth at the same time. WMM employs techniques that are a subset of the developing IEEE 802.11e QoS standard and it enables the access point to inter-operate with both WMM- enabled clients and other devices that may lack any WMM functionality.The WMM commands supported by the access point are listed below.Tabl e 30 WMM Commands wmmThis command sets the WMM operational mode on the access point. Use the no form to disable WMM.Syntax[no] wmm <supported | required> •supported - WMM will be used for any associated device that supports this feature.

DefaultackCommand ModeInterface Configuration (Wireless)Command Usage • WMM defines four access categories (ACs) – voice, video, best effort, and background. These categories correspond to traffic priority levels and are mapped to IEEE 802.1D priority tags (see Table ). The direct mapping of the four ACs to 802.1D priorities is specifically intended to facilitate interpretability with other wired network QoS policies. While the four ACs are specified for specific types of traffic, WMM allows the priority levels to be configured to match any network-wide QoS policy. WMM also specifies a protocol that access points can use to communicate the configured traffic priority levels to QoS-enabled wireless clients.• Although turning off the requirement for the sender to wait for an acknowledgement can increases data throughput, it can also result in a high number of errors when traffic levels are heavy.Enterprise AP(if-wireless a)#wmm requiredEnterprise AP(if-wireless a)#
