Chapter 2: Hardware Installation 1. Select a Site – Choose a proper place for the access point. In general, the best location is at the center of your wireless coverage area, within line of sight of all wireless devices. Try to place the access point in a position that can best cover its Basic Service Set (refer to “Infrastructure Wireless LAN” on page 4-3). For optimum performance, consider these points: • Mount the access point as high as possible above any obstructions in the coverage area.
2 Hardware Installation 4. Observe the Self Test – When you power on the access point, verify that the PWR indicator stops flashing and remains on, and that the other indicators start functioning as described under “LED Indicators” on page 1-3. If the PWR LED does not stop flashing, the self test has not completed correctly. Refer to “Troubleshooting” on page A-1. 5. Connect the Ethernet Cable – The access point can be wired to a 10/100 Mbps Ethernet through a network device such as a hub or a switch.
Chapter 3: External Antennas The SMC WA6102X-2AG provides a variety of external antenna options for extending the radio range and shaping the coverge area. These antennas offer a number of different mounting locations, including indoor or outdoor, wall, ceiling, or radio mast. This chapter shows you how to install an external antenna for your WA6102X-2AG. Only the SMC antennas listed in this guide are permitted to be connected to the WA6102X-2AG.
3 External Antennas Consider these points: • Use the antenna’s mounting bracket or other hardware, if included. • For optimum performance, mount antennas as high as possible above any obstructions, and away from any signal absorbing or reflecting structures (such as those containing metal) • Be sure there are no other radio antennas mounted within 2 m (6 ft). • Consider the antenna’s radio coverage pattern so that it can properly cover the intended service area.
3 Instalation Procedures 3. Connect Pigtail Cables to the Access Point Use the pigtail cables that are attached to the antenna, or are included in the antenna package. If an extension cable is required, please contact a professional installer who is trained in RF installation and knowledgeable in the local regulations. Note that diversity antennas have two pigtail cables. A diversity antenna includes two internal antenna elements that are identical.
3 External Antennas Screw onto access point’s 5. Antenna pigtail cable Reconnect power to the access point. Note: Before enabling the radio with an external antenna attached, be sure to first configure the access point’s antenna mode and transmit power settings.
Chapter 4: Network Configuration Wireless networks support a stand-alone configuration as well as an integrated configuration with 10/100 Mbps Ethernet LANs. The 2.4 GHz/5 GHz Wireless Access Point also provides repeater and bridging services that can be configured independently on either the 5 GHz or 2.4 GHz radio interfaces.
4 Network Configuration Network Topologies Ad Hoc Wireless LAN (no Access Point) An ad hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter, connected via radio signals as an independent wireless LAN. Computers in a specific ad hoc wireless LAN must therefore be configured to the same radio channel. An ad hoc wireless LAN can be used for a branch office or SOHO operation.
Network Topologies 4 Infrastructure Wireless LAN The access point also provides access to a wired LAN for wireless workstations. An integrated wired/wireless LAN is called an Infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless PC users, and an access point that is directly connected to the wired LAN.
4 Network Configuration Infrastructure Wireless LAN for Roaming Wireless PCs The Basic Service Set (BSS) defines the communications domain for each access point and its associated wireless clients. The BSS ID is a 48-bit binary number based on the access point’s wireless MAC address, and is set automatically and transparently as clients associate with the access point. The BSS ID is used in frames sent between the access point and its clients to identify traffic in the service area.
4 Network Topologies Infrastructure Wireless Bridge The IEEE 802.11 standard defines a WIreless Distribution System (WDS) for bridge connections between BSS areas (access points). The access point uses WDS to forward traffic on links between units. The access point supports WDS bridge links on either the 5 GHz (802.11a) or 2.4 GHz (802.11b/g) bands and can be used with various external antennas to offer flexible deployment options.
4 Network Configuration Infrastructure Wireless Repeater The access point can also operate in a bridge “repeater” mode to extend the range of links to wireless clients. The access point uses WDS to forward traffic between the repeater bridge and the root bridge. The access point supports up to six WDS repeater links. In repeater mode, the access point does not support an Ethernet link to a wired LAN. Note that when the access point operates in this mode only half the normal throughput is possible.
Chapter 5: Initial Configuration The 2.4 GHz/5 GHz Wireless Access Point offers a variety of management options, including a web-based interface, a direct connection to the console port, Telnet, Secure Shell (SSH), or using SNMP software. The initial configuration steps can be made through the web browser interface or CLI. The access point requests an IP address via DHCP by default. If no response is received from the DHCP server, then the access point uses the default address 192.168.1.1.
5 Initial Configuration Note: When using HyperTerminal with Microsoft® Windows® 2000, make sure that you have Windows 2000 Service Pack 2 or later installed. Windows 2000 Service Pack 2 fixes the problem of arrow keys not functioning in HyperTerminal’s VT100 emulation. See www.microsoft.com for information on Windows 2000 service packs. 4. Once you have set up the terminal correctly, press the [Enter] key to initiate the console connection. The console login screen will be displayed.
5 Logging In After configuring the access point’s IP parameters, you can access the management interface from anywhere within the attached network. The command line interface can also be accessed using Telnet from any computer attached to the network. Setting the Country Code – Units sold in the United States are configured by default to use only radio channels 1-11 in 802.11b or 802.11g mode as defined by FCC regulations. Units sold in other countries are configured by default without a country code (i.
5 Initial Configuration The home page displays the Main Menu.
Chapter 6: System Configuration Before continuing with advanced configuration, first complete the initial configuration steps described in Chapter 4 to set up an IP address for the access point. The access point can be managed by any computer using a web browser (Internet Explorer 5.0 or above, or Netscape Navigator 6.2 or above). Enter the configured IP address of the access point, or use the default address: http://192.168.1.
6 System Configuration Advanced Configuration The Advanced Configuration pages include the following options. Table 6-2.
Advanced Configuration 6 Table 6-2.
6 System Configuration CLI Commands for System Identification – Enter the global configuration mode, and use the system name command to specify a new system name. Then return to the Exec mode, and use the show system command to display the changes to the system identification settings. Enterprise Enterprise Enterprise Enterprise AP#config AP(config)#system name R&D AP(config)#end AP#show system Enterprise AP#config Enter configuration commands, one per line.
6 Advanced Configuration TCP / IP Settings Configuring the access point with an IP address expands your ability to manage the access point. A number of access point features depend on IP addressing to operate. Note: You can use the web browser interface to access IP addressing only if the access point already has an IP address that is reachable through your network. By default, the access point will be automatically configured with IP settings from a Dynamic Host Configuration Protocol (DHCP) server.
6 System Configuration • Subnet Mask: The mask that identifies the host address bits used for routing to specific subnets. • Default Gateway: The default gateway is the IP address of the router for the access point, which is used if the requested destination address is not on the local subnet. If you have management stations, DNS, RADIUS, or other network servers located on another subnet, type the IP address of the default gateway router in the text field provided.
6 Advanced Configuration RADIUS Remote Authentication Dial-in User Service (RADIUS) is an authentication protocol that uses software running on a central server to control access to RADIUS-aware devices on the network. An authentication server contains a database of user credentials for each user that requires access to the network. A primary RADIUS server must be specified for the access point to implement IEEE 802.1X network access control and Wi-Fi Protected Access (WPA) wireless security.
6 6-8 System Configuration
6 Advanced Configuration Primary Radius Server Setup – Configure the following settings to use RADIUS authentication on the access point. • IP Address: Specifies the IP address or host name of the RADIUS server. • Port: The UDP port number used by the RADIUS server for authentication messages. (Range: 1024-65535; Default: 1812) • Key: A shared text string used to encrypt messages between the access point and the RADIUS server. Be sure that the same text string is specified on the RADIUS server.
6 System Configuration CLI Commands for RADIUS – From the global configuration mode, use the radius-server address command to specify the address of the primary or secondary RADIUS servers. (The following example configures the settings for the primary RADIUS server.) Configure the other parameters for the RADIUS server. Then use the show show radius command from the Exec mode to display the current settings for the primary and secondary RADIUS servers.
Advanced Configuration 6 SSH Settings Telnet is a remote management tool that can be used to configure the access point from anywhere in the network. However, Telnet is not secure from hostile attacks. The Secure Shell (SSH) can act as a secure replacement for Telnet. The SSH protocol uses generated public keys to encrypt all data transfers passing between the access point and SSH-enabled management station clients and ensures that data traveling over the network arrives unaltered.
6 System Configuration Authentication Wireless clients can be authenticated for network access by checking their MAC address against the local database configured on the access point, or by using a database configured on a central RADIUS server. Alternatively, authentication can be implemented using the IEEE 802.1X network access control protocol.
Advanced Configuration 6 MAC Authentication – You can configure a list of the MAC addresses for wireless clients that are authorized to access the network. This provides a basic level of authentication for wireless clients attempting to gain access to the network. A database of authorized MAC addresses can be stored locally on the access point or remotely on a central RADIUS server. (Default: Disabled) • Disabled: No checks are performed on an associating station’s MAC address.
6 System Configuration MAC Authentication Session Timeout – Sets the interval at which associated clients will be re-authenticated with the RADIUS server. (Range: 0-1440 minutes; Default: 0, that is, disabled) WEB Redirect – Enables web-based authentication of wireless clients. This feature supports billing for a public access wireless network without requiring 802.1X or MAC authentication.
Advanced Configuration 6 CLI Commands for Local MAC Authentication – Use the mac-authentication server command from the global configuration mode to enable local MAC authentication. Use the mac-authentication session-timeout command to set the authentication interval, and web-redirect command to enable web-based authentication for service billing.
6 System Configuration CLI Commands for RADIUS MAC Authentication – Use the mac-authentication server command from the global configuration mode to enable remote MAC authentication. Set the timeout value for re-authentication using the macauthentication session-timeout command. Be sure to also configure connection settings for the RADIUS server (not shown in the following example). To display the current settings, use the show authentication command from the Exec mode.
Advanced Configuration 6 Filter Control The access point can employ network traffic frame filtering to control access to network resources and increase security. You can prevent communications between wireless clients and prevent access point management from wireless clients. Also, you can block specific Ethernet traffic from being forwarded by the access point. IAPP – Enables roaming between multi-vendor access points.
6 System Configuration Ethernet Type Filter – Controls checks on the Ethernet type of all incoming and outgoing Ethernet packets against the protocol filtering table. (Default: Disabled) • Disabled: Access point does not filter Ethernet protocol types. • Enabled: Access point filters Ethernet protocol types based on the configuration of protocol types in the filter table. If the status of a protocol is set to “ON,” the protocol is filtered from the access point.
Advanced Configuration 6 VLAN The access point can employ VLAN tagging support to control access to network resources and increase security. VLANs separate traffic passing between the access point, associated clients, and the wired network. There can be a VLAN assigned to each associated client, a default VLAN for each VAP (Virtual Access Point) interface, and a management VLAN for the access point.
6 System Configuration When setting up VLAN IDs for each user on the RADIUS server, be sure to use the RADIUS attributes and values as indicated in the following table. Number RADIUS Attribute Value 64 Tunnel-Type VLAN (13) 65 Tunnel-Medium-Type 802 81 Tunnel-Private-Group-ID VLANID (1 to 4094 as hexadecimal or string) VLAN IDs on the RADIUS server can be entered as hexadecimal digits or a string (see “radius-server vlan-format” on page 7-63).
Advanced Configuration 6 WDS Settings Each access point radio interface can be configured to operate in a bridge or repeater mode, which allows it to forward traffic directly to other access point units. To set up bridge links between access point units, you must configure the WIreless Distribution System (WDS) forwarding table by specifying the wireless MAC address of all units to which you want to forward traffic.
6 System Configuration • Bridge: Operates as a bridge to other access points. The “Parent” link to the root bridge must be configured. Up to five other ”Child” links are available to other bridges. • 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.
Advanced Configuration 6 Spanning Tree Protocol – STP uses a distributed algorithm to select a bridging device (STP-compliant switch, bridge or router) that serves as the root of the spanning tree network. It selects a root port on each bridging device (except for the root device) which incurs the lowest path cost when forwarding a packet from that device to the root device.
6 System Configuration designated ports. After determining the lowest cost spanning tree, it enables all root ports and designated ports, and disables all other ports. Network packets are therefore only forwarded between root ports and designated ports, eliminating any possible network loops. Once a stable network topology has been established, all bridges listen for Hello BPDUs (Bridge Protocol Data Units) transmitted from the root bridge.
Advanced Configuration 6 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.) • Range: 1-65535 • Default: Ethernet interface: 19; Wireless interface: 40 • Link Port Priority – Defines the priority used for this port in the Spanning Tree Protocol. If the path cost for all ports on a switch are the same, the port with the highest priority (i.e.
6 System Configuration CLI Commands for STP Settings – If the role of a radio interface is set to Repeater, Bridge or Root Bridge, STP can be enabled on the access point to maintain a valid network topology. To globally enable STP, use the bridge stp enable command from the CLI configuration mode. Then configure the other global STP parameters for the bridge.
Advanced Configuration 6 AP Management The Web, Telnet, and SNMP management interfaces are enabled and open to all IP addresses by default. To provide more security for management access to the access point, specific interfaces can be disabled and management restricted to a single IP address or a limited range of IP addresses. Once you specify an IP address or range of addresses, access to management interfaces is restricted to the specified addresses.

Advanced Configuration 6 CLI Commands for the Administrator’s User Name and Password – Use the username and password commands from the CLI configuration mode. Enterprise AP(config)#username bob Enterprise AP(config)#password admin Enterprise AP# 7-15 7-15 Upgrading Firmware You can upgrade new access point software from a local file on the management workstation, or from an FTP or TFTP server. New software may be provided periodically from your distributor.
6 System Configuration Before upgrading new software, verify that the access point is connected to the network and has been configured with a compatible IP address and subnet mask. If you need to download from an FTP or TFTP server, take the following additional steps: • Obtain the IP address of the FTP or TFTP server where the access point software is stored. • If upgrading from an FTP server, be sure that you have an account configured on the server with a user name and password.
Advanced Configuration 6 • If VLANs are configured on the access point, determine the VLAN ID with which the FTP or TFTP server is associated, and then configure the management station, or the network port to which it is attached, with the same VLAN ID. If you are managing the access point from a wireless client, the VLAN ID for the wireless client must be configured on a RADIUS server. Current version – Version number of runtime code.
6 System Configuration CLI Commands for Downloading Software from a TFTP Server – Use the copy tftp file command from the Exec mode and then specify the file type, name, and IP address of the TFTP server. When the download is complete, the dir command can be used to check that the new file is present in the access point file system. To run the new software, use the reset board command to reboot the access point. Enterprise AP#copy tftp file 1. Application image 2. Config file 3.
Advanced Configuration 6 System Log The access point can be configured to send event and error messages to a System Log Server. The system clock can also be synchronized with a time server, so that all the messages sent to the Syslog server are stamped with the correct time and date. Enabling System Logging The access point supports a logging process that can control error messages saved to memory or sent to a Syslog server.
6 System Configuration Logging Level – Sets the minimum severity level for event logging. (Default: Informational) The system allows you to limit the messages that are logged by specifying a minimum severity level. The following table lists the error message levels from the most severe (Emergency) to least severe (Debug). The message levels that are logged include the specified minimum level up to the Emergency level.
Advanced Configuration 6 CLI Commands for System Logging – To enable logging on the access point, use the logging on command from the global configuration mode. The logging level command sets the minimum level of message to log. Use the logging console command to enable logging to the console. Use the logging host command to specify up to four Syslog servers. The CLI also allows the logging facility-type command to set the facility-type number to use on the Syslog server.
6 System Configuration Note: The access point also allows you to disable SNTP and set the system clock manually. Set Time Zone – SNTP uses Coordinated Universal Time (or UTC, formerly Greenwich Mean Time, or GMT) based on the time at the Earth’s prime meridian, zero degrees longitude. To display a time corresponding to your local time, you must indicate the number of hours your time zone is located before (east) or after (west) UTC.
SNMP 6 CLI Commands for the System Clock – The following example shows how to manually set the system time when SNTP server support is disabled on the access point. Enterprise AP(config)#no sntp-server enable Enterprise AP(config)#sntp-server date-time Enter Year<1970-2100>: 2003 Enter Month<1-12>: 10 Enter Day<1-31>: 10 Enter Hour<0-23>: 18 Enter Min<0-59>: 35 Enterprise AP(config)# 7-34 7-35 RSSI The RSSI page displays the ambient noise floor for both radios A and G.
6 System Configuration The access point includes an onboard agent that supports SNMP versions 1, 2c, and 3 clients. This agent continuously monitors the status of the access point, as well as the traffic passing to and from wireless clients. A network management station can access this information using SNMP management software that is compliant with MIB II. To implement SNMP management, the access point must first have an IP address and subnet mask, configured either manually or dynamically.
SNMP 6 SNMP – Enables or disables SNMP management access and also enables the access point to send SNMP traps (notifications). (Default: Disable) Location – A text string that describes the system location. (Maximum length: 255 characters) Contact – A text string that describes the system contact. (Maximum length: 255 characters) Community Name (Read Only) – Defines the SNMP community access string that has read-only access. Authorized management stations are only able to retrieve MIB objects.
6 System Configuration Trap Configuration – Allows selection of specific SNMP notifications to send.

Radio Interface 6 Radio Settings A (802.11a) The IEEE 802.11a interface operates within the 5 GHz band, at up to 54 Mbps in normal mode or up to 108 Mbps in Turbo mode. First configure the radio settings that apply to the individual VAPs (Virtual Access Point) and the common radio settings that apply to the overall system. After you have configured the radio settings, go to the Security page under the 802.
6 System Configuration Default VLAN ID – The VLAN ID assigned to wireless clients associated to the VAP interface that are not assigned to a specific VLAN by RADIUS server configuration. (Default: 1) Closed System – When enabled, the VAP interface does not include its SSID in beacon messages. Nor does it respond to probe requests from clients that do not include a fixed SSID.
Radio Interface 6 CLI Commands for the Configuring the VAPs – From the global configuration mode, enter the interface wireless a command to access the 802.11a radio interface. From the 802.11a interface mode, you can access radio settings that apply to all VAP interfaces. To access a specific VAP interface (numbered 0 to 3), use the vap command. You can configure a name for each interface using the description command. You can also use the closed-system command to stop sending the SSID in beacon messages.
6 System Configuration The access point can be configured to periodically scan all radio channels and find other access points within range. A database of nearby access points is maintained where any rogue APs can be identified. During a scan, Syslog messages (see “Enabling System Logging” on page 6-33) are sent for each access point detected. Rogue access points can be identified by unknown BSSID (MAC address) or SSID configuration. • AP Detection – Enables the periodic scanning for other access points.
Radio Interface 6 using the rogue-ap scan command. To view the database of detected access points, use the show rogue-ap command from the Exec level. Enterprise AP(config)#interface wireless g 7-87 Enter Wireless configuration commands, one per line. 7-111 Enterprise AP(if-wireless g)#rogue-ap enable configure either syslog or trap or both to receive the rogue APs detected.
6 System Configuration Configuring Common Radio Settings To configure Rouge AP detection, select the Radio Settings page, and scroll down to the “Rouge AP” section. Turbo Mode – The normal 802.11a wireless operation mode provides connections up to 54 Mbps. Turbo Mode is an enhanced mode (not regulated in IEEE 802.11a) that provides a higher data rate of up to 108 Mbps. Enabling Turbo Mode allows the access point to provide connections up to 108 Mbps.
Radio Interface 6 Radio Channel – The radio channel that the access point uses Normal Mode to communicate with wireless clients. When multiple access points are deployed in the same area, set the channel on neighboring access points at least four channels apart to avoid interference with each other. For example, in the United States you can deploy up to four access points in the same area (e.g., channels 36, 56, 149, 165).
6 System Configuration Antenna Control Method - Selects the use of both fixed antennas operating in diversity mode or a single antenna. (Default: Diversity) • Diversity: The radio uses both antennas in a diversity system. 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. • Right: The radio only uses the antenna on the right side (the side closest to the access point LEDs).
Radio Interface 6 (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.
6 System Configuration CLI Commands for the Common Radio Settings – From the global configuration mode, enter the interface wireless a command to access the 802.11a radio interface. From the 802.11a interface mode, you can access radio settings that apply to all VAP interfaces. Use the turbo command to enable this feature before setting the radio channel with the channel command. Set any other radio setting as required before enabling the VAP interface (with the no shutdown command).
Radio Interface 6 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. Table 6-1.

For information on the these command, refer to the following sections: • • • • “Configuring VAP Radio Settings” on page 6-49 “Configuring Rogue AP Detection” on page 6-51 “Configuring Common Radio Settings” on page 6-54 “Configuring Wi-Fi Multimedia” on page 6-58 Only the radio settings unique to the 802.11g interface are included in this section. To configure the 802.
Radio Interface 6 Radio Channel – The radio channel that the access point uses to communicate with wireless clients. When multiple access points are deployed in the same area, set the channel on neighboring access points at least five channels apart to avoid interference with each other. For example, in the United States you can deploy up to three access points in the same area (e.g., channels 1, 6, 11).
6 System Configuration CLI Commands for the 802.11g Wireless Interface – From the global configuration mode, enter the interface wireless g command to access the 802.11g radio interface. The 802.11g radio can be forced to an 802.11g-only, 802.11b-only, or mixed 802.11b/g operating mode using the radio-mode command. You should set the desired operating mode before configuring channel settings (the default is mixed 802.11b/g operation).
Radio Interface 6 A summary of wireless security considerations is listed in the following table. Table 6-2. Wireless Security Considerations Security Mechanism Client Support Implementation Considerations WEP Built-in support on all 802.11a and 802.11g devices • Provides only weak security • Requires manual key management WEP over 802.1X Requires 802.
6 System Configuration The access point can simultaneously support clients using various different security mechanisms. The configuration for these security combinations are outlined in the following table. Note that MAC address authentication can be configured independently to work with all security mechanisms and is indicated separately in the table. Required RADIUS server support is also listed. Table 6-3. Security Combinations Client Security Combination Configuration Summarya MAC Auth.

Security Combinations Client Security Combination Configuration Summarya MAC Auth.b RADIUS Server Static WEP and WPA Pre-Shared Key 802.1X: Disable Enter 1 to 4 WEP keys Select a WEP transmit key VAP interface settings: Authentication Type: Open System Data Encryption: Enable WPA Clients: Supported WPA Key Mode: WPA Pre-shared Key Enter a WPA Pre-shared key WPA Multicast Cipher: WEP Local only No Dynamic WEP and 802.1X WPA 802.1X: Required Set 802.
6 System Configuration Enabling the VAPs Before enabling the Virtual Access Point (VAP) radio interfaces, first configure all of the relevant raido settings (see “Radio Settings A (802.11a)” on page 6-49 or “Radio Settings G (802.11g)” on page 6-63.) After you have configured the radio settnings, select Security under Radio A or Radio G, set an SSID to identify the wireless network service provided by each VAP you want to use, and then click Apply to save your settings.
Radio Interface 6 Wired Equivalent Privacy (WEP) WEP provides a basic level of security, preventing unauthorized access to the network, and encrypting data transmitted between wireless clients and the access point. WEP uses static shared keys (fixed-length hexadecimal or alphanumeric strings) that are manually distributed to all clients that want to use the network. WEP is the security protocol initially specified in the IEEE 802.11 standard for wireless communications.
6 System Configuration Key Number – Selects the key number to use for encryption for each VAP interface. If the clients have all four keys configured to the same values, you can change the encryption key to any of the four settings without having to update the client keys. (Default: Key 1) Shared Key Setup – Select 64 Bit, 128 Bit, or 152 Bit key length. Note that the same size of encryption key must be supported on all wireless clients.
Radio Interface 6 Data Encryption – Enable or disable the access point to use data encryption (WEP, TKIP, or AES). If this option is selected when using static WEP keys, you must configure at least one key on the access point and all clients. (Default: Disabled) Note: You must enable data encryption through the web or CLI in order to enable all types of encryption (WEP, TKIP, or AES) in the access point. CLI Commands for WEP Shared Key Security – For static WEP shared keys, be sure to first disable 802.

Radio Interface 6 CLI Commands for WEP over 802.1X Security – First set 802.1X to required using the 802.1X command and set the 802.1X key refresh rates. Then, from the 802.11a or 802.11g interface configuration mode, use the vap command to access each VAP interface to configure other security settings. From the VAP interface configuration mode, use the authentication command to select open system authentication and the encryption command to enable data encryption.
6 System Configuration to encrypt each data packet. TKIP provides further data encryption enhancements by including a message integrity check for each packet and a re-keying mechanism, which periodically changes the master key. WPA Pre-Shared Key Mode (WPA-PSK, WPA2-PSK): For enterprise deployment, WPA requires a RADIUS authentication server to be configured on the wired network.
Radio Interface 6 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. • Key Caching: 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, re-authentication is not required.
6 System Configuration To configure WPA, click Security under Radio A or Radio G. Select one of the VAP interfaces by clicking More. Select one of the WPA options in the Authentication Setup table, and then configure the parameters displayed beneath the table. The WPA configuration parameters are described below: Data Encryption Mode – You must enable data encryption in order to enable all types of encryption (WEP, TKIP, or AES) in the access point. Pre-Authentication – When using WPA2 over 802.
Radio Interface 6 • WPA: Clients using WPA over 802.1X are accepted for authentication. • WPA-PSK: Clients using WPA with a Pre-shared Key are accepted for authentication. • WPA2: Clients using WPA2 over 802.1X are accepted for authentication. • WPA2-PSK: Clients using WPA2 with a Pre-shared Key are accepted for authentication. • WPA-WPA2-mixed: Clients using WPA or WPA2 over 802.1X are accepted for authentication.
6 System Configuration The configuration settings for WPA are summarized below: Table 6-4. WPA Configuration Settings WPA and WPA2 pre-shared key only WPA and WPA2 over 802.
Radio Interface 6 CLI Commands for WPA Over 802.1X Security – First set 802.1X to required using the 802.1X command and set the 802.1X key refresh rates. Then, from the 802.11a or 802.11g interface configuration mode, use the vap command to access each VAP interface to configure other security settings. From the VAP interface configuration mode, use the authentication command to select open system authentication and the encryption command to enable data encryption.
6 System Configuration Open the Security page, and click More for one of the VAP interfaces. You can enable 802.1X as optionally supported or as required to enhance the security of the wireless network. (Default: Disable) • Disable: The access point does not support 802.1X authentication for any wireless client. After successful wireless association with the access point, each client is allowed to access the network. • Supported: The access point supports 802.
Radio Interface 6 • 802.1X Reauthentication Refresh Rate: The time period after which a connected client must be re-authenticated. During the re-authentication process of verifying the client’s credentials on the RADIUS server, the client remains connected the network. Only if re-authentication fails is network access blocked. (Range: 0-65535 seconds; Default: 0 means disabled) CLI Commands for 802.1X Authentication – Use the 802.1X supported command from the VAP interface mode to enable 802.

Chapter 7: Command Line Interface Using the Command Line Interface Accessing the CLI When 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 Connection To access the access point through the console port, perform these steps: 1.
7 Command Line Interface 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.
Entering Commands 7 Command Completion If 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 Commands You 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.
7 Command Line Interface Partial Keyword Lookup If 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.
Entering Commands 7 Exec Commands When 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.
7 Command Line Interface Command Line Processing Commands 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: Table 7-1.

7 Command Line Interface • 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 7-112).
Rogue AP Detection Commands 7 rogue-ap duration This command sets the scan duration for detecting access points. Syntax rogue-ap duration milliseconds - The duration of the scan. (Range: 100-1000 milliseconds) Default Setting 350 milliseconds Command Mode Interface Configuration (Wireless) Command Usage • During a scan, client access may be disrupted and new clients may not be able to associate to the access point. If clients experience severe disruption, reduce the scan duration time.
7 Command Line Interface Example Enterprise AP(if-wireless g)#rogue-ap interval 120 Enterprise AP(if-wireless g)# Related Commands rogue-ap duration (7-113) rogue-ap scan This command starts an immediate scan for access points on the radio interface. Default Setting Disabled Command Mode Interface Configuration (Wireless) Command Usage While the access point scans a channel for rogue APs, wireless clients will not be able to connect to the access point.

Syntax transmit-key index - Key index.
Wireless Security Commands 7 cipher-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. Syntax multicast-cipher • 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.
7 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.
Wireless Security Commands 7 Example Enterprise AP(if-wireless a)#mic_mode hardware Enterprise AP(if-wireless g)# wpa-pre-shared-key This command defines a Wi-Fi Protected Access (WPA/WPA2) preshared-key.

Appendix A: Troubleshooting Check the following items before you contact local Technical Support. 1. If wireless clients cannot access the network, check the following: • Be sure the access point and the wireless clients are configured with the same Service Set ID (SSID). • If authentication or encryption are enabled, ensure that the wireless clients are properly configured with the appropriate authentication or encryption keys.
A 3. Troubleshooting If you cannot access the on-board configuration program via a serial port connection: • Be sure you have set the terminal emulator program to VT100 compatible, 8 data bits, 1 stop bit, no parity and 9600 bps. • Check that the null-modem serial cable conforms to the pin-out connections provided on page B-3. 4. If you forgot or lost the password: • Set the access point to its default configuration by pressing the reset button on the back panel for 5 seconds or more.
Appendix B: Cables and Pinouts Twisted-Pair Cable Assignments For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.
