System Clock Commands Command Function Mode Page sntp-server ip Specifies one or more time servers GC 7-34 sntp-server enable Accepts time from the specified time servers GC 7-34 sntp-server date-time Manually sets the system date and time GC 7-35 sntp-server daylight-saving Sets the start and end dates for daylight savings time GC 7-36 sntp-server timezone Sets the time zone for the bridge’s internal clock GC 7-36 show sntp Shows current SNTP configuration settings Exec 7-37 7-33 7 Command Line Interface sntp-server ip This command sets the IP address of the servers to which SNTP time requests are issued. Use the this command with no arguments to clear all time servers from the current list. Syntax sntp-server ip <1 | 2> • 1 - First time server. • 2 - Second time server. • ip - IP address of an time server (NTP or SNTP). Default Setting 137.92.140.80 192.43.244.18 Command Mode Global Configuration Command Usage When SNTP client mode is enabled using the sntp-server enable command, the sntp-server ip command specifies the time servers from which the bridge polls for time updates. The bridge will poll the time servers in the order specified until a response is received. Example Enterprise AP(config)#sntp-server ip 10.1.0.19 Enterprise AP# Related Commands sntp-server enable (7-34) show sntp (7-37) sntp-server enable This command enables SNTP client requests for time synchronization with NTP or SNTP time servers specified by the sntp-server ip command. Use the no form to disable SNTP client requests. Syntax sntp-server enable no sntp-server enable Default Setting Enabled 7-34 System Clock Commands Command Mode Global Configuration Command Usage The time acquired from time servers is used to record accurate dates and times for log events. Without SNTP, the bridge only records the time starting from the factory default set at the last bootup (i.e., 00:14:00, January 1, 1970). Example Enterprise AP(config)#sntp-server enable Enterprise AP(config)# Related Commands sntp-server ip (7-34) show sntp (7-37) sntp-server date-time This command sets the system clock. Default Setting 00:14:00, January 1, 1970 Command Mode Global Configuration Example This example sets the system clock to 17:37 June 19, 2003. Enterprise AP#sntp-server date-time Enter Year<1970-2100>: 2003 Enter Month<1-12>: 6 Enter Day<1-31>: 19 Enter Hour<0-23>: 17 Enter Min<0-59>: 37 Enterprise AP# Related Commands sntp-server enable (7-34) 7-35 7 Command Line Interface sntp-server daylight-saving This command sets the start and end dates for daylight savings time. Use the no form to disable daylight savings time. Syntax sntp-server daylight-saving no sntp-server daylight-saving Default Setting Disabled Command Mode Global Configuration Command Usage The command sets the system clock back one hour during the specified period. Example This sets daylight savings time to be used from July 1st to September 1st. Enterprise AP(config)#sntp-server daylight-saving Enter Daylight saving from which month<1-12>: 6 and which day<1-31>: 1 Enter Daylight saving end to which month<1-12>: 9 and which day<1-31>: 1 Enterprise AP(config)# sntp-server timezone This command sets the time zone for the bridge’s internal clock. Syntax sntp-server timezone hours - Number of hours before/after UTC. (Range: -12 to +12 hours) Default Setting -5 (BOGOTA, EASTERN, INDIANA) Command Mode Global Configuration 7-36 System Clock Commands Command Usage This command sets the local time zone relative to the Coordinated Universal Time (UTC, formerly Greenwich Mean Time or GMT), based on the earth’s prime meridian, zero degrees longitude. To display a time corresponding to your local time, you must indicate the number of hours and minutes your time zone is east (before) or west (after) of UTC. Example Enterprise AP(config)#sntp-server timezone +8 Enterprise AP(config)# show sntp This command displays the current time and configuration settings for the SNTP client. Command Mode Exec Example Enterprise AP#show sntp SNTP Information ========================================================= Service State : Enabled SNTP (server 1) IP : 137.92.140.80 SNTP (server 2) IP : 192.43.244.18 Current Time : 08 : 04, Jun 20th, 2003 Time Zone : +8 (TAIPEI, BEIJING) Daylight Saving : Enabled, from Jun, 1st to Sep, 1st ========================================================= Enterprise AP# 7-37 7 Command Line Interface DHCP Relay Commands Dynamic 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 bridge’s DHCP relay agent is enabled, received client requests can be forwarded directly by the bridge to a known DHCP server on another subnet. Responses from the DHCP server are returned to the bridge, which then broadcasts them back to clients. Table 7-8. DHCP Relay Commands Command Function Mode dhcp-relay enable Enables the DHCP relay agent GC Page 7-38 dhcp-relay Sets the primary and secondary DHCP server address GC 7-39 show dhcp-relay Shows current DHCP relay configuration settings Exec 7-39 dhcp-relay enable This command enables the bridge’s DHCP relay agent. Use the no form to disable the agent. Syntax [no] dhcp-relay enable Default Setting Disabled Command Mode Global Configuration Command 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 Enterprise AP(config)#dhcp-relay enable Enterprise AP(config)# 7-38 DHCP Relay Commands dhcp-relay This command configures the primary and secondary DHCP server addresses. Syntax dhcp-relay • primary - The primary DHCP server. • secondary - The secondary DHCP server. • ip_address - IP address of the server. Default Setting Primary and secondary: 0.0.0.0 Command Mode Global Configuration Example Enterprise AP(config)#dhcp-relay primary 192.168.1.10 Enterprise AP(config)# show dhcp-relay This command displays the current DHCP relay configuration. Command Mode Exec Example Enterprise AP#show dhcp-relay DHCP Relay : ENABLED Primary DHCP Server : 192.168.1.10 Secondary DHCP Server : 0.0.0.0 Enterprise AP# 7-39 7 Command Line Interface SNMP Commands Controls access to this bridge from management stations using the Simple Network Management Protocol (SNMP), as well as the hosts that will receive trap messages.

(Range: 1-63 characters) community-string - Password-like community string sent with the notification operation. Although you can set this string using the snmp-server host command by itself, we recommend that you define this string using the snmp-server community command prior to using the snmp-server host command. (Maximum length: 23 characters) Default Setting Host Address: None Community String: public Command Mode Global Configuration 7-43 7 Command Line Interface Command Usage The snmp-server host command is used in conjunction with the snmp-server enable server command to enable SNMP notifications. Example Enterprise AP(config)#snmp-server host 1 10.1.19.23 batman Enterprise AP(config)# Related Commands snmp-server enable server (7-42) snmp-server trap This command enables the bridge to send specific SNMP traps (i.e., notifications). Use the no form to disable specific trap messages. Syntax snmp-server trap no snmp-server trap • trap - One of the following SNMP trap messages: - dot11InterfaceAGFail - The 802.11a or 802.11g interface has failed. - dot11InterfaceBFail - The 802.11b interface has failed. - dot11StationAssociation - A client station has successfully associated with the bridge. - dot11StationAuthentication - A client station has been successfully authenticated. - dot11StationReAssociation - A client station has successfully re-associated with the bridge. - dot11StationRequestFail - A client station has failed association, re-association, or authentication. - dot1xAuthFail - A 802.1X client station has failed RADIUS authentication. - dot1xAuthNotInitiated - A client station did not initiate 802.1X authentication. - dot1xAuthSuccess - A 802.1X client station has been successfully authenticated by the RADIUS server. - dot1xMacAddrAuthFail - A client station has failed MAC address authentication with the RADIUS server. - dot1xMacAddrAuthSuccess - A client station has successfully authenticated its MAC address with the RADIUS server. - iappContextDataSent - A client station’s Context Data has been sent to another bridge with which the station has associated. - iappStationRoamedFrom - A client station has roamed from another bridge (identified by its IP address). 7-44 SNMP Commands - iappStationRoamedTo - A client station has roamed to another bridge (identified by its IP address). - localMacAddrAuthFail - A client station has failed authentication with the local MAC address database on the bridge. - localMacAddrAuthSuccess - A client station has successfully authenticated its MAC address with the local database on the bridge. - pppLogonFail - The bridge has failed to log onto the PPPoE server using the configured user name and password. - sntpServerFail - The bridge has failed to set the time from the configured SNTP server. - sysConfigFileVersionChanged - The bridge’s configuration file has been changed. - sysRadiusServerChanged - The bridge has changed from the primary RADIUS server to the secondary, or from the secondary to the primary. - sysSystemDown - The bridge is about to shutdown and reboot. - sysSystemUp - The bridge is up and running. Default Setting All traps enabled Command Mode Global Configuration Command Usage This command is used in conjunction with the snmp-server host and snmp-server enable server commands to enable SNMP notifications. Example Enterprise AP(config)#no snmp-server trap dot11StationAssociation Enterprise AP(config)# snmp-server engine-id This command is used for SNMP v3. It is used to uniquely identify the bridge among all bridges in the network. Use the no form to delete the engine ID. Syntax snmp-server engine-id no snmp-server engine-id engine-id - Enter engine-id in hexadecimal (5-32 characters). Default Setting Enabled 7-45 7 Command Line Interface Command Mode Global Configuration Command Usage • This command is used in conjunction with the snmp-server user command. • Entering this command invalidates all engine IDs that have been previously configured. • If the engineID is deleted or changed, all SNMP users will be cleared. You will need to reconfigure all existing users Example Enterprise AP(config)#snmp-server engine-id 1a:2b:3c:4d:00:ff Enterprise AP(config)# snmp-server user This command configures the SNMP v3 users that are allowed to manage the bridge. Use the no form to delete an SNMP v3 user. Syntax snmp-server user user-name - A user-defined string for the SNMP user. (32 characters maximum) Default Setting None Command Mode Global Configuration Command Usage • Up to 10 SNMPv3 users can be configured on the bridge. • The SNMP engine ID is used to compute the authentication/privacy digests from the pass phrase. You should therefore configure the engine ID with the snmp-server engine-id command before using this configuration command. • The bridge 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. 7-46 SNMP Commands • • • • - 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) - group-name - The name of the SNMP group to which the user is assigned (32 characters maximum). There are three pre-defined groups: RO, RWAuth, or RWPriv. - auth-proto - The authentication type used for user authentication: md5 or none. - auth-passphrase - The user password required when authentication is used (8 – 32 characters). - priv-proto - The encryption type used for SNMP data encryption: des or none. - priv-passphrase - The user password required when data encryption is used (8 – 32 characters). Users must be assigned to groups that have the same security levels. If a user who has “AuthPriv” security (uses authentication and encryption) is assigned to a read-only (RO) group, the user will not be able to access the database. An AuthPriv user must be assigned to the RWPriv group with the AuthPriv security level. To configure a user for the RWAuth group, you must include the auth-proto and auth-passphrase keywords. To configure a user for the RWPriv group, you must include the auth-proto, auth-passphrase, priv-proto, and priv-passphrase keywords. Example Enterprise AP(config)#snmp-server user User Name<1-32> :chris Group Name<1-32> :RWPriv Authtype(md5,none):md5 Passphrase<8-32>:a good secret Privacy(des,none) :des Passphrase<8-32>:a very good secret Enterprise AP(config)# 7-47 7 Command Line Interface snmp-server targets This command configures SNMP v3 notification targets. Use the no form to delete an SNMP v3 target. Syntax snmp-server targets [version {3}] [udp-port {port-number}] [notification-type {TRAP}] no snmp-server targets • target-id - A user-defined name that identifies a receiver of SNMP notifications. (Maximum length: 32 characters) • ip-addr - Specifies the IP address of the management station to receive notifications. • sec-name - The defined SNMP v3 user name that is to receive notifications. • version - The SNMP version of notifications. Currently only version 3 is supported in this command. • udp-port - The UDP port that is used on the receiving management station for notifications. • notification-type - The type of notification that is sent. Currently only TRAP is supported. Default Setting None Command Mode Global Configuration Command Usage • The bridge supports up to 10 SNMP v3 target IDs. • The SNMP v3 user name that is specified in the target must first be configured using the snmp-server user command. Example Enterprise AP(config)#snmp-server targets mytraps 192.168.1.33 chris Enterprise AP(config)# 7-48 SNMP Commands snmp-server filter This command configures SNMP v3 notification filters. Use the no form to delete an SNMP v3 filter or remove a subtree from a filter. Syntax snmp-server filter [mask {mask}] no snmp-server filter [subtree] • filter-id - A user-defined name that identifies an SNMP v3 notification filter. (Maximum length: 32 characters) • include - Defines a filter type that includes objects in the MIB subtree. • exclude - Defines a filter type that excludes objects in the MIB subtree. • subtree - The part of the MIB subtree that is to be filtered. • mask - An optional hexadecimal value bit mask to define objects in the MIB subtree. Default Setting None Command Mode Global Configuration Command Usage • The bridge allows up to 10 notification filters to be created. Each filter can be defined by up to 20 MIB subtree ID entries. • Use the command more than once with the same filter ID to build a filter that includes or excludes multiple MIB objects. Note that the filter entries are applied in the sequence that they are defined. • The MIB subtree must be defined in the form “.1.3.6.1” and always start with a “.”. • The mask is a hexadecimal value with each bit masking the corresponding ID in the MIB subtree. A “1” in the mask indicates an exact match and a “0” indicates a “wild card.” For example, a mask value of 0xFFBF provides a bit mask “1111 1111 1011 1111.” If applied to the subtree 1.3.6.1.2.1.2.2.1.1.23, the zero corresponds to the 10th subtree ID. When there are more subtree IDs than bits in the mask, the mask is padded with ones. Example Enterprise AP(config)#snmp-server filter trapfilter include .1 Enterprise AP(config)#snmp-server filter trapfilter exclude .1.3.6.1.2.1.2.2.1.1.23 7-49 7 Command Line Interface snmp-server filter-assignments This command assigns SNMP v3 notification filters to targets. Use the no form to remove an SNMP v3 filter assignment. Syntax snmp-server filter-assignments no snmp-server filter-assignments • target-id - A user-defined name that identifies a receiver of SNMP notifications. (Maximum length: 32 characters) • filter-id - A user-defined name that identifies an SNMP v3 notification filter.

This control feature prevents unauthorized access to the network by requiring an 802.1X client application to submit user credentials for authentication. Client authentication is then verified by a RADIUS server using EAP (Extensible Authentication Protocol) before the bridge grants client access to the network. The 802.1X EAP packets are also used to pass dynamic unicast session keys and static broadcast keys to wireless clients. Table 7-12. 802.1X Authentication Command Function Mode Page 802.1x Configures 802.1X as disabled, supported, or required IC-W-VAP 7-65 802.1x broadcast-keyrefresh-rate Sets the interval at which the primary broadcast keys are IC-W-VAP refreshed for stations using 802.1X dynamic keying 7-66 802.1x session-keyrefresh-rate Sets the interval at which unicast session keys are IC-W-VAP refreshed for associated stations using dynamic keying 7-67 802.1x session-timeout Sets the timeout after which a connected client must be IC-W-VAP re-authenticated 7-67 802.1x-supplicant enable Enables the bridge to operate as a 802.1X supplicant GC 7-68 802.1x-supplicant user Sets the supplicant user name and password for the bridge GC 7-68 show authentication Shows all 802.1X authentication settings, as well as the Exec address filter table 7-68 802.1x This command configures 802.1X as optionally supported or as required for wireless clients. Use the no form to disable 802.1X support. Syntax 802.1x no 802.1x • supported - Authenticates clients that initiate the 802.1X authentication process. Uses standard 802.11 authentication for all others. • required - Requires 802.1X authentication for all clients. Default Setting Disabled 7-65 7 Command Line Interface Command Mode Global Configuration Command Usage • When 802.1X is disabled, the bridge does not support 802.1X authentication for any station. After successful 802.11 association, each client is allowed to access the network. • When 802.1X is supported, the bridge supports 802.1X authentication only for clients initiating the 802.1X authentication process (i.e., the bridge does NOT initiate 802.1X authentication). For stations initiating 802.1X, only those stations successfully authenticated are allowed to access the network. For those stations not initiating 802.1X, access to the network is allowed after successful 802.11 association. • When 802.1X is required, the bridge enforces 802.1X authentication for all 802.11 associated stations. If 802.1X authentication is not initiated by the station, the bridge will initiate authentication. Only those stations successfully authenticated with 802.1X are allowed to access the network. • 802.1X does not apply to the 10/100Base-TX port. Example Enterprise AP(config)#802.1x supported Enterprise AP(config)# 802.1x broadcast-key-refresh-rate This command sets the interval at which the broadcast keys are refreshed for stations using 802.1X dynamic keying. Syntax 802.1x broadcast-key-refresh-rate rate - The interval at which the bridge rotates broadcast keys. (Range: 0 1440 minutes) Default Setting 0 (Disabled) Command Mode Global Configuration Command Usage • The bridge uses Enterprise APOL (Extensible Authentication Protocol Over LANs) packets to pass dynamic unicast session and broadcast keys to wireless clients. The 802.1x broadcast-key-refresh-rate command specifies the interval after which the broadcast keys are changed. The 802.1x session-key-refresh-rate command specifies the interval after which unicast session keys are changed. 7-66 802.1X Authentication • Dynamic broadcast key rotation allows the bridge to generate a random group key and periodically update all key-management capable wireless clients.

Syntax bridge role • ap - Operates only as an bridge 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 bridges also in bridge mode. • root-bridge - Operates as the root bridge in the wireless bridge network. Default Setting AP Command 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 7-78). When the bridge 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-bridge Enterprise AP(if-wireless a)# bridge-link parent This command configures the MAC address of the parent bridge node.

Syntax bridge stp enable no bridge stp enable Default Setting Enabled Command Mode Global Configuration Example This example globally enables the Spanning Tree Protocol. Enterprise AP(config)bridge stp enable Enterprise AP(config) 7-83 7 Command Line Interface bridge stp forwarding-delay Use this command to configure the spanning tree bridge forward time globally for the wireless bridge. Use the no form to restore the default. Syntax bridge stp forwarding-delay no bridge stp forwarding-delay seconds - Time in seconds. (Range: 4 - 30 seconds) The minimum value is the higher of 4 or [(max-age / 2) + 1]. Default Setting 15 seconds Command Mode Global Configuration Command 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 Enterprise AP(config)#bridge stp forwarding-delay 20 Enterprise AP(config)# bridge stp hello-time Use 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 • a - 802.11a radio interface. • g - 802.11g radio interface. 7-94 Wireless Interface Commands Default Setting None Command Mode Global Configuration Example To specify the 802.11a interface, enter the following command: Enterprise AP(config)#interface wireless a Enterprise AP(if-wireless a)# vap This command provides access to the VAP (Virtual bridge) interface configuration mode. Syntax vap vap-id - The number that identifies the VAP interface. (Options: 0-7) Default Setting None Command Mode Interface Configuration (Wireless) Example Enterprise AP(if-wireless g)#vap 0 Enterprise AP(if-wireless g: VAP[0])# speed This command configures the maximum data rate at which the bridge transmits unicast packets. Syntax speed speed - Maximum access speed allowed for wireless clients. (Options for 802.11a: 6, 9, 12, 18, 24, 36, 48, 54 Mbps) (Options for 802.11b/g: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps) 7-95 7 Command Line Interface Default Setting 54 Mbps Command Mode Interface Configuration (Wireless) Command Usage • The maximum transmission distance is affected by the data rate. The lower the data rate, the longer the transmission distance. Please refer to the table for maximum distances on page -6. • When turbo mode is enabled (page 7-107) for 802.11a, the effective maximum speed specified by this command is double the entered value (e.g., setting the speed to 54 Mbps limits the effective maximum speed to 108 Mbps). Example Enterprise AP(if-wireless g)#speed 6 Enterprise AP(if-wireless g)# turbo This command sets the bridge to an enhanced proprietary modulation mode (not regulated in IEEE 802.11a) that provides a higher data rate of up to 108 Mbps. Syntax turbo no turbo static - Always uses turbo mode. dynamic - Will use turbo mode when no other nearby bridges are detected or active. Default Setting Disabled Command Mode Interface Configuration (Wireless - 802.11a) Command Usage • 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 bridge to provide connections up to 108 Mbps. • In normal mode, the bridge provides a channel bandwidth of 20 MHz, and supports the maximum number of channels permitted by local regulations (e.g., 11 channels for the United States). In Turbo Mode, the channel bandwidth is increased to 40 MHz to support the increased data rate. 7-96 Wireless Interface Commands However, this reduces the number of channels supported (e.g., 5 channels for the United States). Example Enterprise AP(if-wireless a)#turbo Enterprise AP(if-wireless a)# multicast-data-rate This command configures the maximum data rate at which the bridge transmits multicast and management packets (excluding beacon packets) on the wireless interface. Syntax multicast-data-rate speed - Maximum transmit speed allowed for multicast data. (Options for 802.11a: 6, 12, 24 Mbps) (Options for 802.11b/g; 1, 2, 5.5, 11 Mbps) Default Setting 1 Mbps for 802.11b/g 6 Mbps for 802.11a Command Mode Interface Configuration (Wireless) Example Enterprise AP(if-wireless g)#multicast-data-rate 5.5 Enterprise AP(if-wireless g)# 7-97 7 Command Line Interface channel This command configures the radio channel through which the bridge communicates with wireless clients. Syntax channel • channel - Manually sets the radio channel used for communications with wireless clients. (Range for 802.11a: 36, 40, 44, 48, 52, 56, 60, 64, 149, 153, 157, 161, 165 for normal mode, and 42, 50, 58, 152, 160 for turbo mode; Range for 802.11b/g: 1 to 14) • auto - Automatically selects an unoccupied channel (if available). Otherwise, the lowest channel is selected. Default Setting Automatic channel selection Command Mode Interface Configuration (Wireless) Command Usage • The available channel settings are limited by local regulations, which determine the number of channels that are available. • When multiple bridges are deployed in the same area, be sure to choose a channel separated by at least two channels for 802.11a to avoid having the channels interfere with each other, and at least five channels for 802.11b/ g. You can deploy up to four bridges in the same area for 802.11a (e.g., channels 36, 56, 149, 165) and three bridges for 802.11b/g (e.g., channels 1, 6, 11). • For most wireless adapters, the channel for wireless clients is automatically set to the same as that used by the bridge to which it is linked. Example Enterprise AP(if-wireless g)#channel 1 Enterprise AP(if-wireless g)# transmit-power This command adjusts the power of the radio signals transmitted from the bridge. Syntax transmit-power signal-strength - Signal strength transmitted from the bridge. (Options: full, half, quarter, eighth, min) 7-98 Wireless Interface Commands Default Setting full Command Mode Interface Configuration (Wireless) Command Usage • The “min” keyword indicates minimum power. • The longer the transmission distance, the higher the transmission power required. 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 Enterprise AP(if-wireless g)#transmit-power half Enterprise AP(if-wireless g)# radio-mode This command forces the operating mode for the 802.11g wireless interface. Syntax radio-mode • b - b-only mode: Both 802.11b and 802.11g clients can communicate with the bridge, 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 bridge (up to 54 Mbps). • b+g - b & g mixed mode: Both 802.11b and 802.11g clients can communicate with the bridge (up to 54 Mbps). Default Setting b+g mode Command Mode Interface Configuration (Wireless - 802.11g) Command Usage • For Japan, only 13 channels are available when set to g or b+g modes. When set to b mode, 14 channels are available. • Both the 802.11g and 802.11b standards operate within the 2.4 GHz band. If you are operating in g mode, any 802.11b devices in the service area will contribute to the radio frequency noise and affect network performance. 7-99 7 Command Line Interface Example Enterprise AP(if-wireless g)#radio-mode g Enterprise AP(if-wireless g)# preamble This command sets the length of the signal preamble that is used at the start of a 802.11b/g data transmission. Syntax preamble [long | short-or-long] • long - Sets the preamble to long (192 microseconds). • short-or-long - Sets the preamble to short if no 802.11b clients are detected (96 microseconds). Default Setting Short-or-Long Command Mode Interface Configuration (Wireless - 802.11b/g) Command Usage • Using a short preamble instead of a long preamble can increase data throughput on the bridge, but requires that all clients can support a short preamble. • Set the preamble to long to ensure the bridge can support all 802.11b and 802.11g clients. Example Enterprise AP(if-wireless g)#preamble short Enterprise AP(if-wireless g)# antenna control This command selects the use of two diversity antennas or a single antenna for the radio interface. Syntax antenna control • 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 bridge's integrated antennas. The bridge does not support external diversity antennas. • left - The radio only uses the antenna on the left side (the side farthest from the bridge LEDs). The bridge does not support an external antenna connection on its left antenna. Therefore, this method is not valid for the bridge. 7-100 Wireless Interface Commands • right - The radio only uses the antenna on the right side (the side closest to the bridge LEDs). Select this method when using an optional external antenna that is connected to the right antenna connector. Default Setting Diversity Command Mode Interface Configuration (Wireless) Command Usage The antenna ID must be selected in conjunction with the antenna control method to configure proper use of any of the antenna options. Example Enterprise AP(if-wireless g)#antenna control right Enterprise AP(if-wireless g)# antenna id This command specifies the antenna type connected to the bridge represented by a four-digit hexadecimal ID number, either the integrated diversity antennas (the "Default Antenna") or an optional external antenna. Syntax antenna id • antenna-id - Specifies the ID number of an approved antenna that is connected to the bridge (Range: 0x0000 - 0xFFFF) Default Setting 0x0000 (built-in antennas) Command Mode Interface Configuration (Wireless) Command Usage • The optional external antennas (if any) that are certified for use with the bridge are listed by typing antenna control id ?. Selecting the correct antenna ID ensures that the bridge's radio transmissions are within regulatory power limits for the country of operation. • The antenna ID must be selected in conjunction with the antenna control method to configure proper use of any of the antenna options. Example Enterprise AP(if-wireless g)#antenna id 0000 Enterprise AP(if-wireless g)# 7-101 7 Command Line Interface antenna location This command selects the antenna mounting location for the radio interface. Syntax antenna location • indoor - The antenna is mounted indoors. • outdoor - The antenna is mounted outdoors. Default Setting Indoor Command Mode Interface Configuration (Wireless) Command Usage • When an external antenna is selected, the antenna control must be set to “right.” • Selecting the correct location ensures that the bridge only uses radio channels that are permitted in the country of operation. Example Enterprise AP(if-wireless g)#antenna location indoor Enterprise AP(if-wireless g)# beacon-interval This command configures the rate at which beacon signals are transmitted from the bridge. Syntax beacon-interval interval - The rate for transmitting beacon signals. (Range: 20-1000 milliseconds) Default Setting 100 Command Mode Interface Configuration (Wireless) Command Usage The beacon signals allow wireless clients to maintain contact with the bridge. They may also carry power-management information. 7-102 Wireless Interface Commands Example Enterprise AP(if-wireless g)#beacon-interval 150 Enterprise AP(if-wireless g)# dtim-period This command configures the rate at which stations in sleep mode must wake up to receive broadcast/multicast transmissions. Syntax dtim-period interval - Interval between the beacon frames that transmit broadcast or multicast traffic. (Range: 1-255 beacon frames) Default Setting Command 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 bridge 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. Example Enterprise AP(if-wireless g)#dtim-period 100 Enterprise AP(if-wireless g)# 7-103 7 Command Line Interface fragmentation-length This command configures the minimum packet size that can be fragmented when passing through the bridge. Syntax fragmentation-length length - Minimum packet size for which fragmentation is allowed. (Range: 256-2346 bytes) Default Setting 2346 Command 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. Example Enterprise AP(if-wireless g)#fragmentation-length 512 Enterprise AP(if-wireless g)# rts-threshold This 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. Syntax rts-threshold threshold - Threshold packet size for which to send an RTS. (Range: 0-2347 bytes) 7-104 Wireless Interface Commands Default Setting 2347 Command Mode Interface Configuration (Wireless) Command Usage • If the threshold is set to 0, the bridge always sends RTS signals. If set to 2347, the bridge 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 bridge 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. • bridges contending for the wireless medium may not be aware of each other. The RTS/CTS mechanism can solve this “Hidden Node” problem. Example Enterprise AP(if-wireless g)#rts-threshold 256 Enterprise AP(if-wireless g)# super-a This command enables Atheros proprietary Super A performance enhancements. Use the no form to disable this function. Syntax [no] super-a Default Setting Disabled Command Mode Interface Configuration (Wireless - 802.11a) Command Usage Super A enhancements include bursting, compression, and fast frames. Maximum throughput ranges between 40 to 60 Mbps for connections to Atheros-compatible clients. Example Enterprise AP(if-wireless a)#super a Enterprise AP(if-wireless a)# 7-105 7 Command Line Interface super-g This command enables Atheros proprietary Super G performance enhancements. Use the no form to disable this function. Syntax [no] super-g Default Setting Disabled Command Mode Interface Configuration (Wireless - 802.11g) Command Usage These enhancements include bursting, compression, fast frames and dynamic turbo. Maximum throughput ranges between 40 to 60 Mbps for connections to Atheros-compatible clients. Example Enterprise AP(if-wireless a)#super g Enterprise AP(if-wireless a)# description This command adds a description to a the wireless interface. Use the no form to remove the description. Syntax description no description string - Comment or a description for this interface. (Range: 1-80 characters) Default Setting None Command Mode Interface Configuration (Wireless-VAP) Example Enterprise AP(if-wireless g: VAP[0])#description RD-AP#3 Enterprise AP(if-wireless g: VAP[0])# 7-106 Wireless Interface Commands ssid This command configures the service set identifier (SSID). Syntax ssid string - The name of a basic service set supported by the bridge. (Range: 1 - 32 characters) Default Setting 802.11a Radio: VAP_TEST_11A (0 to 3) 802.11g Radio: VAP_TEST_11G (0 to 3) Command Mode Interface Configuration (Wireless-VAP) Command Usage Clients that want to connect to the wireless network via an bridge must set their SSIDs to the same as that of the bridge. Example Enterprise AP(if-wireless g: VAP[0])#ssid RD-AP#3 Enterprise AP(if-wireless g)# closed-system This command prohibits access to clients without a pre-configured SSID. Use the no form to disable this feature. Syntax closed-system no closed-system Default Setting Disabled Command Mode Interface Configuration (Wireless-VAP) Command Usage When closed system is enabled, the bridge will not include its SSID in beacon messages. Nor will it respond to probe requests from clients that do not include a fixed SSID. Example Enterprise AP(if-wireless g: VAP[0])#closed-system Enterprise AP(if-wireless g)# 7-107 7 Command Line Interface max-association This command configures the maximum number of clients that can be associated with the bridge at the same time. Syntax max-association count - Maximum number of associated stations. (Range: 0-64) Default Setting 64 Command Mode Interface Configuration (Wireless-VAP) Example Enterprise AP(if-wireless g: VAP[0])#max-association 32 Enterprise AP(if-wireless g)# assoc-timeout-interval This command configures the idle time interval (when no frames are sent) after which the client is disassociated from the VAP interface. Syntax assoc-timeout-interval minutes - The number of minutes of inactivity before disassociation. (Range: 5-60) Default Setting 30 Command Mode Interface Configuration (Wireless-VAP) Example Enterprise AP(if-wireless g: VAP[0])#association-timeout-interval 20 Enterprise AP(if-wireless g: VAP[0])# auth-timeout-value This command configures the time interval within which clients must complete authentication to the VAP interface. Syntax auth-timeout-value minutes - The number of minutes before re-authentication. (Range: 5-60) 7-108 Wireless Interface Commands Default Setting 60 Command Mode Interface Configuration (Wireless-VAP) Example Enterprise AP(if-wireless g: VAP[0])#auth-timeout-value 40 Enterprise AP(if-wireless g: VAP[0])# shutdown This command disables the wireless interface. Use the no form to restart the interface. Syntax shutdown no shutdown Default Setting Interface enabled Command Mode Interface Configuration (Wireless-VAP) Command Usage You must first enable VAP interface 0 before you can enable VAP interfaces 1, 2, 3, 4, 5, 6, or 7. Example Enterprise AP(if-wireless g: VAP[0])#shutdown Enterprise AP(if-wireless g)# 7-109 7 Command Line Interface show interface wireless This command displays the status for the wireless interface. Syntax show interface wireless vap-id • a - 802.11a radio interface. • g - 802.11g radio interface. • vap-id - The number that identifies the VAP interface.

Enterprise AP# 7-112 Rogue AP Detection Commands Rogue AP Detection Commands A “rogue AP” is either an bridge that is not authorized to participate in the wireless network, or an bridge that does not have the correct security configuration. Rogue APs can potentially allow unauthorized users access to the network. Alternatively, client stations may mistakenly associate to a rogue AP and be prevented from accessing network resources. Rogue APs may also cause radio interference and degrade the wireless LAN performance. The bridge can be configured to periodically scan all radio channels and find other bridges within range. A database of nearby bridges is maintained where any rogue APs can be identified. Table 7-18. Rogue AP Detection Commands Command Function Mode Page rogue-ap enable Enables the periodic detection of other nearby bridges GC 7-113 rogue-ap authenticate Enables identification of all bridges GC 7-114 rogue-ap duration Sets the duration that all channels are scanned GC 7-114 rogue-ap interval Sets the time between each scan GC 7-115 rogue-ap scan Forces an immediate scan of all radio channels GC 7-116 show rogue-ap Shows the current database of detected bridges Exec 7-117 rogue-ap enable This command enables the periodic detection of nearby bridges. Use the no form to disable periodic detection. Syntax [no] rogue-ap enable Default Setting Disabled Command Mode Interface Configuration (Wireless) Command Usage • While the bridge scans a channel for rogue APs, wireless clients will not be able to connect to the bridge. 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. 7-113 7 Command Line Interface • A “rogue AP” is either an bridge that is not authorized to participate in the wireless network, or an bridge that does not have the correct security configuration. Rogue bridges can be identified by unknown BSSID (MAC address) or SSID configuration. A database of nearby bridges should therefore be maintained on a RADIUS server, allowing any rogue APs to be identified (see “rogue-ap authenticate” on page 7-114). The rogue AP database can be viewed using the show rogue-ap command. • The bridge sends Syslog messages for each detected bridge during a rogue AP scan. Example Enterprise AP(if-wireless g)#rogue-ap enable configure either syslog or trap or both to receive the rogue APs detected. Enterprise AP(if-wireless g)# rogue-ap authenticate This command forces the unit to authenticate all bridges on the network. Use the no form to disable this function. Syntax [no] rogue-ap authenticate Default Setting Disabled Command Mode Interface Configuration (Wireless) Command Usage Enabling authentication in conjunction with a database of approved bridges stored on a RADIUS server allows the bridge to discover rogue APs. With authentication enabled and a configure RADIUS server, the bridge checks the MAC address/Basic Service Set Identifier (BSSID) of each bridge that it finds against a RADIUS server to determine whether the bridge is allowed. With authentication disabled, the bridge can identify its neighboring bridges only; it cannot identify whether the bridges are allowed or are rogues. If you enable authentication, you should also configure a RADIUS server for this bridge (see “Radius” on page 6-7). Example Enterprise AP(if-wireless g)#rogue-ap authenticate Enterprise AP(if-wireless g)# rogue-ap duration This command sets the scan duration for detecting bridges. 7-114 Rogue AP Detection Commands 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 bridge. If clients experience severe disruption, reduce the scan duration time. • A long scan duration time will detect more bridges in the area, but causes more disruption to client access. Example Enterprise AP(if-wireless g)#rogue-ap duration 200 Enterprise AP(if-wireless g)# Related Commands rogue-ap interval (7-115) rogue-ap interval This command sets the interval at which to scan for bridges. Syntax rogue-ap interval minutes - The interval between consecutive scans. (Range: 30-10080 minutes) Default Setting 720 minutes Command Mode Interface Configuration (Wireless) Command Usage This command sets the interval at which scans occur. Frequent scanning will more readily detect other bridges, but will cause more disruption to client access. 7-115 7 Command Line Interface Example Enterprise AP(if-wireless g)#rogue-ap interval 120 Enterprise AP(if-wireless g)# Related Commands rogue-ap duration (7-114) rogue-ap scan This command starts an immediate scan for bridges on the radio interface. Default Setting Disabled Command Mode Interface Configuration (Wireless) Command Usage While the bridge scans a channel for rogue APs, wireless clients will not be able to connect to the bridge. 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.

Syntax auth • open-system - Accepts the client without verifying its identity using a shared key. “Open” authentication means either there is no encryption (if encryption is disabled) or WEP-only encryption is used (if encryption is enabled). • shared-key - Authentication is based on a shared key that has been distributed to all stations. • wpa - Clients using WPA are accepted for authentication. • wpa-psk - Clients using WPA with a Pre-shared Key are accepted for authentication. • wpa2 - Clients using WPA2 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 are accepted for authentication. • wpa-wpa2-psk-mixed - Clients using WPA or WPA2 with a Pre-shared Key are accepted for authentication • required - Clients are required to use WPA or WPA2. • supported - Clients may use WPA or WPA2, if supported. Default Setting open-system Command Mode Interface Configuration (Wireless-VAP) Command Usage • The auth command automatically configures settings for each authentication type, including encryption, 802.1X, and cipher suite. The command auth open-system disables encryption and 802.1X. 7-118 Wireless Security Commands • 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 7-65) and RADIUS server details (see “RADIUS Client” on page 7-59) must be configured on the bridge. 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 7-65) and RADIUS server details (see “RADIUS Client” on page 7-59) 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 bridge. Use the wpa-preshared-key command to configure the key (see “key” on page 7-121 and “transmit-key” on page 7-122). • 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 bridge 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 bridge. 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 WEP). To place the VAP into AES only mode, use “required” and then select the “cipher-ccmp” option for the cipher-suite command. 7-119 7 Command Line Interface Example Enterprise AP(if-wireless g: VAP[0])#auth shared-key Enterprise AP(if-wireless g)# Related Commands encryption (7-120) key (7-121) encryption This command enables data encryption for wireless communications. Use the no form to disable data encryption. Syntax encryption no encryption Default Setting disabled Command Mode Interface Configuration (Wireless-VAP) Command Usage • Wired Equivalent Privacy (WEP) is implemented in this device to prevent unauthorized access to your wireless network. For more secure data transmissions, enable encryption with this command, and set at least one static WEP key with the key command. • The WEP settings must be the same on each client in your wireless network. • Note that WEP protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet. • You must enable data encryption in order to enable all types of encryption (WEP, TKIP, and AES-CCMP) in the bridge. Example Enterprise AP(if-wireless g: VAP[0])#encryption Enterprise AP(if-wireless g)# Related Commands key (7-121) 7-120 Wireless Security Commands key This command sets the keys used for WEP encryption. Use the no form to delete a configured key. Syntax key no key index • • • • index - Key index. (Range: 1-4) size - Key size. (Options: 64, 128, or 152 bits) type - Input format. (Options: ASCII, HEX) value - The key string. - For 64-bit keys, use 5 alphanumeric characters or 10 hexadecimal digits. - For 128-bit keys, use 13 alphanumeric characters or 26 hexadecimal digits. - For 152-bit keys, use 16 alphanumeric characters or 32 hexadecimal digits. Default Setting None Command Mode Interface Configuration (Wireless) Command Usage • To enable Wired Equivalent Privacy (WEP), use the auth shared-key command to select the “shared key” authentication type, use the key command to configure at least one key, and use the transmit-key command to assign a key to one of the VAP interfaces. • If WEP option is enabled, all wireless clients must be configured with the same shared keys to communicate with the bridge. • The encryption index, length and type configured in the bridge must match those configured in the clients. Example Enterprise Enterprise Enterprise Enterprise AP(if-wireless AP(if-wireless AP(if-wireless AP(if-wireless g)#key 1 64 hex 1234512345 g)#key 2 128 ascii asdeipadjsipd g)#key 3 64 hex 12345123451234512345123456 g)# Related Commands key (7-121) encryption (7-120) transmit-key (7-122) 7-121 7 Command Line Interface transmit-key This command sets the index of the key to be used for encrypting data frames for broadcast or multicast traffic transmitted from the VAP to wireless clients. Syntax transmit-key index - Key index. (Range: 1-4) Default Setting Command Mode Interface Configuration (Wireless-VAP) Command Usage • If you use WEP key encryption option, the bridge uses the transmit key to encrypt multicast and broadcast data signals that it sends to client devices. Other keys can be used for decryption of data from clients. • When using IEEE 802.1X, the bridge uses a dynamic key to encrypt unicast and broadcast messages to 802.1X-enabled clients. However, because the bridge 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 bridge uses transmit key index 1 for the generation of dynamic keys. Example Enterprise AP(if-wireless g: VAP[0])#transmit-key 2 Enterprise AP(if-wireless g)# 7-122 Wireless Security Commands 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. • 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 wep Command Mode Interface Configuration (Wireless-VAP) Command Usage • WPA enables the bridge 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 bridge are not WPA enabled, the multicast-cipher 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. 7-123 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. 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 Enterprise AP(if-wireless g: VAP[0])#multicast-cipher TKIP Enterprise AP(if-wireless g)# mic_mode This command specifies how to calculate the Message Integrity Check (MIC). Syntax mic_mode • hardware - Uses hardware to calculate the MIC. • software - Uses software to calculate the MIC. Default Setting software Command 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 bridge for each transmitted packet and this can impact throughput and performance. The bridge supports a choice of hardware or software for MIC calculation. The performance of the bridge 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. • 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. 7-124 Wireless Security Commands 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) Pre-shared-key. Syntax wpa-pre-shared-key • 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 bridge’s VAP interface. Example Enterprise AP(if-wireless g: VAP[0])#wpa-pre-shared-key ASCII agoodsecret Enterprise AP(if-wireless g)# Related Commands auth (7-118) pmksa-lifetime This command sets the time for aging out cached WPA2 Pairwise Master Key Security Association (PMKSA) information for fast roaming. Syntax pmksa-lifetime minutes - The time for aging out PMKSA information. (Range: 0 - 14400 minutes) Default Setting 720 minutes 7-125 7 Command Line Interface Command 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 bridge 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 bridge 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 bridge, it requires full reauthentication. • The bridge can store up to 256 entries in the PMKSA cache. Example Enterprise AP(if-wireless g: VAP[0])#wpa-pre-shared-key ASCII agoodsecret Enterprise AP(if-wireless g: VAP[0])# pre-authentication This command enables WPA2 pre-authentication for fast secure roaming. Syntax pre-authentication • enable - Enables pre-authentication for the VAP interface. • disable - Disables pre-authentication for the VAP interface. Default Setting Disabled Command Mode Interface Configuration (Wireless-VAP) Command Usage • Each time a client roams to another bridge 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 bridge 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 bridge in the network, the bridge sends pre-authentication messages to the new bridge that include the client’s security association information. Then when the client sends an association request to the new bridge the client is known to be already authenticated, 7-126 Link Integrity Commands so it proceeds directly to key exchange and association. • To support pre-authentication, both clients and bridges in the network must be WPA2 enabled. • Pre-authentication requires all bridges in the network to be on the same IP subnet. Example Enterprise AP(if-wireless g: VAP[0])#wpa-pre-shared-key ASCII agoodsecret Enterprise AP(if-wireless g: VAP[0])# Link Integrity Commands The bridge provides a link integrity feature that can be used to ensure that wireless clients are connected to resources on the wired network. The bridge does this by periodically sending Ping messages to a host device in the wired Ethernet network. If the bridge detects that the connection to the host has failed, it disables the radio interfaces, forcing clients to find and associate with another bridge. When the connection to the host is restored, the bridge re-enables the radio interfaces. Table 7-20. Link Integrity Commands Command Function Mode Page link-integrity ping-detect Enables link integrity detection GC 7-128 link-integrity ping-host Specifies the IP address of a host device in the wired network GC 7-128 link-integrity ping-interval Specifies the time between each Ping sent to the link host GC 7-129 link-integrity ping-fail-retry Specifies the number of consecutive failed Ping counts before the link is determined as lost GC 7-129 link-integrity ethernet-detect Enables integrity check for Ethernet link GC 7-129 show link-integrity Displays the current link integrity configuration Exec 7-130 7-127 7 Command Line Interface link-integrity ping-detect This command enables link integrity detection. Use the no form to disable link integrity detection. Syntax [no] link-integrity ping-detect Default Setting Disabled Command Mode Global Configuration Command Usage • When link integrity is enabled, the IP address of a host device in the wired network must be specified. • The bridge periodically sends an ICMP echo request (Ping) packet to the link host IP address. When the number of failed responses (either the host does not respond or is unreachable) exceeds the limit set by the link-integrity ping-fail-retry command, the link is determined as lost. Example Enterprise AP(config)#link-integrity ping-detect Enterprise AP(config)# link-integrity ping-host This command configures the link host name or IP address. Use the no form to remove the host setting. Syntax link-integrity ping-host no link-integrity ping-host • host_name - Alias of the host. • ip_address - IP address of the host.

In other words, the 802.11f protocol can ensure successful roaming between bridges in a multi-vendor environment. iapp This command enables the protocol signaling required to hand over wireless clients roaming between different 802.11f-compliant bridges. Use the no form to disable 802.11f signaling. Syntax [no] iapp Default Enabled Command Mode Global Configuration Command Usage The current 802.11 standard does not specify the signaling required between bridges in order to support clients roaming from one bridge to another. In particular, this can create a problem for clients roaming between bridges from different vendors. This command is used to enable or disable 802.11f handover signaling between different bridges, especially in a multi-vendor environment. Example Enterprise AP(config)#iapp Enterprise AP(config)# 7-131 7 Command Line Interface VLAN Commands The bridge 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 bridge, 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 bridge assigns the user to its own configured native VLAN ID. Caution: When VLANs are enabled, the bridge’s Ethernet port drops all received traffic that does not include a VLAN tag. To maintain network connectivity to the bridge and wireless clients, be sure that the bridge is connected to a device port on a wired network that supports IEEE 802.1Q VLAN tags. The VLAN commands supported by the bridge are listed below. Table 7-21. VLAN Commands Command Function Mode Page vlan Enables a single VLAN for all traffic GC 7-132 managementvlanid Configures the management VLAN for the bridge GC 7-133 vlan-id Configures the default VLAN for the VAP interface IC-W-VAP 7-133 vlan This command enables VLANs for all traffic. Use the no form to disable VLANs. Syntax [no] vlan enable Default Disabled Command Mode Global Configuration Command Description • When VLANs are enabled, the bridge tags frames received from wireless clients with the VLAN ID configured for each client on the RADIUS server. If the VLAN ID has not been configured for a client on the RADIUS server, then the frames are tagged with the bridge’s native VLAN ID. 7-132 VLAN Commands • Traffic entering the Ethernet port must be tagged with a VLAN ID that matches the bridge’s native VLAN ID, or with a VLAN tag that matches one of the wireless clients currently associated with the bridge. Example Enterprise AP(config)#vlan enable Reboot system now? : y Related Commands management-vlanid (7-133) management-vlanid This command configures the management VLAN ID for the bridge. Syntax management-vlanid vlan-id - Management VLAN ID. (Range: 1-4094) Default Setting Command Mode Global Configuration Command Usage The management VLAN is for managing the bridge. For example, the bridge allows traffic that is tagged with the specified VLAN to manage the bridge via remote management, SSH, SNMP, Telnet, etc. Example Enterprise AP(config)#management-vlanid 3 Enterprise AP(config)# Related Commands vlan (7-132) vlan-id This command configures the default VLAN ID for the VAP interface. Syntax vlan-id vlan-id - Native VLAN ID. (Range: 1-4094) 7-133 7 Command Line Interface Default Setting Command Mode Interface Configuration (Wireless-VAP) Command Usage • To implement the default VLAN ID setting for VAP interface, the bridge must enable VLAN support using the vlan command. • When VLANs are enabled, the bridge tags frames received from wireless clients with the default VLAN ID for the VAP interface. If IEEE 802.1X is being used to authenticate wireless clients, specific VLAN IDs can be configured on the RADIUS server to be assigned to each client. Using IEEE 802.1X and a central RADIUS server, up to 64 VLAN IDs can be mapped to specific wireless clients. • If the VLAN ID has not been configured for a client on the RADIUS server, then the frames are tagged with the default VLAN ID of the VAP interface. Example Enterprise AP(if-wireless g: VAP[0])#vlan-id 3 Enterprise AP(if-wireless g: VAP[0])# WMM Commands The bridge implements QoS using the Wi-Fi Multimedia (WMM) standard. Using WMM, the bridge 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 bridge to inter-operate with both WMM- enabled clients and other devices that may lack any WMM functionality. The WMM commands supported by the bridge are listed below. Table 7-22. WMM Commands Command Function Mode Page wmm Sets the WMM operational mode on the bridge IC-W 7-135 wmm-acknowledgepolicy Allows the acknowledgement wait time to be enabled or IC-W disabled for each Access Category (AC) 7-135 wmmparam Configures detailed WMM parameters that apply to the bridge (AP) or the wireless clients (BSS) 7-136 7-134 IC-W WMM Commands wmm This command sets the WMM operational mode on the bridge. Use the no form to disable WMM. Syntax [no] wmm • supported - WMM will be used for any associated device that supports this feature. Devices that do not support this feature may still associate with the bridge. • required - WMM must be supported on any device trying to associated with the bridge. Devices that do not support this feature will not be allowed to associate with the bridge. Default supported Command Mode Interface Configuration (Wireless) Example Enterprise AP(if-wireless a)#wmm required Enterprise AP(if-wireless a)# wmm-acknowledge-policy This command allows the acknowledgement wait time to be enabled or disabled for each Access Category (AC). Syntax wmm-acknowledge-policy • ac_number - Access categories. (Range: 0-3) • ack - Require the sender to wait for an acknowledgement from the receiver. • noack - Does not require the sender to wait for an acknowledgement from the receiver. Default ack Command Mode Interface 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 6-1). The direct mapping of the four ACs to 802.1D priorities is specifically intended to facilitate 7-135 7 Command Line Interface 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 bridges 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. Example Enterprise AP(if-wireless a)#wmm-acknowledge-policy 0 noack Enterprise AP(if-wireless a)# wmmparam This command configures detailed WMM parameters that apply to the bridge (AP) or the wireless clients (BSS). Syntax wmmparam • AP - Access Point • BSS - Wireless client • ac_number - 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 as shown in Table 6-1. (Range: 0-3) • LogCwMin - Minimum log value of the contention window. This is the initial upper limit of the random backoff wait time before wireless medium access can be attempted. The initial wait time is a random value between zero and the LogCwMin value. Specify the LogCwMin value. Note that the LogCwMin value must be equal or less than the LogCwMax value. (Range: 1-15 microseconds) • LogCwMax - Maximum log value of the contention window. This is the maximum upper limit of the random backoff wait time before wireless medium access can be attempted. The contention window is doubled after each detected collision up to the LogCwMax value. Note that the CWMax value must be greater or equal to the LogCwMin value. (Range: 1-15 microseconds) • AIFS - Arbitrary InterFrame Space specifies the minimum amount of wait time before the next data transmission attempt. (Range: 1-15 microseconds) • TXOPLimit - Transmission Opportunity Limit specifies the maximum time an AC transmit queue has access to the wireless medium. When an AC queue is granted a transmit opportunity, it can transmit data for a time up to the TxOpLimit. This data bursting greatly improves the efficiency for high data-rate traffic. (Range: 0-65535 microseconds) 7-136 WMM Commands • admission_control - The admission control mode for the access category. When enabled, clients are blocked from using the access category. (Options: 0 to disable, 1 to enable) Default AP Parameters WMM Parameters AC0 (Best Effort) AC1 (Background) AC2 (Video) AC3 (Voice) LogCwMin LogCwMax 10 10 AIFS TXOP Limit 94 47 Admission Control Disabled Disabled Disabled Disabled WMM Parameters AC0 (Best Effort) AC1 (Background) AC2 (Video) AC3 (Voice) LogCwMin LogCwMax 10 AIFS TXOP Limit 94 47 Admission Control Disabled Disabled Disabled Disabled BSS Parameters Command Mode Interface Configuration (Wireless) Example Enterprise AP(if-wireless a)#wmmparams ap 0 4 6 3 1 1 Enterprise AP(if-wireless a)# 7-137 7 Command Line Interface 7-138 A TROUBLESHOOTING Check the following items before you contact local Technical Support. 1 If wireless bridge units do not associate with each other, check the following: Check the power injector LED for each bridge unit to be sure that power is being supplied Be sure that antennas in the link are properly aligned. Be sure that channel settings match on all bridges If encryption is enabled, ensure that all bridge links are configured with the same encryption keys. 2 If you experience poor performance (high packet loss rate) over the wireless bridge link: Check that the range of the link is within the limits for the antennas used. Be sure that antennas in the link are properly aligned. Check that there is an unobstructed radio line-of-sight between the antennas. Be sure there is no interference from other radio sources. Try setting the bridge link to another radio channel. Be sure there is no other radio transmitter too close to either antenna. If necessary, move the antennas to another location. 3 If wireless clients cannot access the network, check the following: Be sure the bridge 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. If authentication is being performed through a RADIUS server, ensure that the clients are properly configured on the RADIUS server. If authentication is being performed through IEEE 802.1X, be sure the wireless users have installed and properly configured 802.1X client software. If MAC address filtering is enabled, be sure the client’s address is included in the local filtering database or on the RADIUS server database. If the wireless clients are roaming between bridges, make sure that all the bridges and wireless devices in the Extended Service Set (ESS) are configured to the same SSID, and authentication method. 4 If the bridge cannot be configured using the Telnet, a web browser, or SNMP software: Be sure to have configured the bridge with a valid IP address, subnet mask and default gateway. If VLANs are enabled on the bridge, the management station should be configured to send tagged frames with a VLAN ID that matches the bridge’s management VLAN (default VLAN 1, page 18). However, to manage the bridge from a wireless client, the AP Management Filter should be disabled (page 18).

A-13 A-14 C 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. CAUTION: DO NOT plug a phone jack connector into a power injector RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards. The following figure illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins. C-1 10/100BASE-TX PIN ASSIGNMENTS Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet). The RJ-45 Input port on the power injector is wired with MDI pinouts. This means that you must use crossover cables for connections to PCs or servers, and straight-through cable for connections to switches or hubs. However, when connecting to devices that support automatic MDI/MDI-X pinout configuration, you can use either straight-through or crossover cable. 10/100BASE-TX MDI and MDI-X Port Pinouts Pin MDI-X Signal Name MDI Signal Name Receive Data plus (RD+) Transmit Data plus (TD+) Receive Data minus (RD-) Transmit Data minus (TD-) Transmit Data plus (TD+) Receive Data plus (RD+) Transmit Data minus (TD-) Receive Data minus (RD-) 4,5,7,8 Not used Not used Note: The “+” and “-” signs represent the polarity of the wires that make up each wire pair. C-2 STRAIGHT-THROUGH WIRING Because the 10/100 Mbps Input port on the power injector uses an MDI pin configuration, you must use “straight-through” cable for network connections to hubs or switches that only have MDI-X ports. However, if the device to which you are connecting supports automatic MDI/MDI-X operation, you can use either “straight-through” or “crossover” cable.

However, if the device to which you are connecting supports automatic MDI/MDI-X operation, you can use either “straight-through” or “crossover” cable. EIA/TIA 568B RJ-45 Wiring Standard 10/100BASE-TX Crossover Cable White/Orange Stripe Orange End A White/Green Stripe Blue White/Blue Stripe Green White/Brown Stripe Brown C-4 End B 8-PIN DIN CONNECTOR PINOUT The Ethernet cable from the power injector connects to an 8-pin DIN connector on the wireless bridge. This connector is described in the following figure and table. 8-Pin DIN Ethernet Port Pinout Pin Signal Name Transmit Data plus (TD+) Transmit Data minus (TD-) Receive Data plus (RD+) +48 VDC power +48 VDC power Receive Data minus (RD-) Return power Return power Note: The “+” and “-” signs represent the polarity of the wires that make up each wire pair. C-5 8-PIN DIN TO RJ-45 CABLE WIRING To construct an extended Ethernet cable to connect from the power injector’s RJ-45 Output port to the wireless bridge’s 8-pin DIN connector, follow the wiring diagram below. Use Category 5 or better UTP or STP cable, maximum length 100 m (328 ft), and be sure to connect all four wire pairs. NOTE: To construct a reliable Ethernet cable, always use the proper tools or ask a professional cable supplier to construct the cable.

D-7 D-8 GLOSSARY 10BASE-T IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3 or better UTP cable. 100BASE-TX IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5 or better UTP cable. Access Point An internetworking device that seamlessly connects wired and wireless networks. Access points attached to a wired network, support the creation of multiple radio cells that enable roaming throughout a facility. Ad Hoc A group of computers connected as an independent wireless network, without an access point. Advanced Encryption Standard (AES) An encryption algorithm that implements symmetric key cryptography. AES provides very strong encryption using a completely different ciphering algorithm to TKIP and WEP. Authentication The process to verify the identity of a client requesting network access. IEEE 802.11 specifies two forms of authentication: open system and shared key. Backbone The core infrastructure of a network. The portion of the network that transports information from one central location to another central location where it is unloaded onto a local system. Basic Service Set (BSS) A set of 802.11-compliant stations and an access point that operate as a fully-connected wireless network. Beacon A signal periodically transmitted from the access point that is used to identify the service set, and to maintain contact with wireless clients. Glossary-1 Broadcast Key Broadcast keys are sent to stations using 802.1X dynamic keying. Dynamic broadcast key rotation is often used to allow the access point to generate a random group key and periodically update all key-management capable wireless clients. CSMA/CA Carrier Sense Multiple Access with Collision Avoidance. Dynamic Host Configuration Protocol (DHCP) Provides a framework for passing configuration information to hosts on a TCP/IP network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability of automatic allocation of reusable network addresses and additional configuration options. Encryption Data passing between the access point and clients can use encryption to protect from interception and evesdropping. Extended Service Set (ESS) More than one wireless cell can be configured with the same Service Set Identifier to allow mobile users can roam between different cells with the Extended Service Set. Extensible Authentication Protocol (EAP) An authentication protocol used to authenticate network clients. EAP is combined with IEEE 802.1X port authentication and a RADIUS authentication server to provide “mutual authentication” between a client, the access point, and the a RADIUS server Ethernet A popular local area data communications network, which accepts transmission from computers and terminals. File Transfer Protocol (FTP) A TCP/IP protocol used for file transfer. Hypertext Transfer Protocol (HTTP) HTTP is a standard used to transmit and receive all data over the World Wide Web. IEEE 802.11a A wireless standard that supports high-speed communications in the 5 GHz band using Orthogonal Frequency Division Multiplexing (OFDM). The standard supports data rates of 6, 12, 24, and 54 Mbps. Glossary-2 IEEE 802.11b A wireless standard that supports wireless communications in the 2.4 GHz band using Direct Sequence Spread Spectrum (DSSS). The standard provides for data rates of 1, 2, 5.5, and 11 Mbps. IEEE 802.11g A wireless standard that supports wireless communications in the 2.4 GHz band using using Orthogonal Frequency Division Multiplexing (OFDM). The standard provides for data rates of 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps. IEEE 802.11g is also backward compatible with IEEE 802.11b. IEEE 802.1X Port Authentication controls access to the switch ports by requiring users to first enter a user ID and password for authentication. Infrastructure An integrated wireless and wired LAN is called an infrastructure configuration. Inter Access Point Protocol (IAPP) A protocol that specifies the wireless signaling required to ensure the successful handover of wireless clients roaming between different 802.11f-compliant access points. Local Area Network (LAN) A group of interconnected computer and support devices. MAC Address The physical layer address used to uniquely identify network nodes. Network Time Protocol (NTP) NTP provides the mechanisms to synchronize time across the network. The time servers operate in a hierarchical-master-slave configuration in order to synchronize local clocks within the subnet and to national time standards via wire or radio. Open System A security option which broadcasts a beacon signal including the access point’s configured SSID. Wireless clients can read the SSID from the beacon, and automatically reset their SSID to allow immediate connection to the nearest access point. Orthogonal Frequency Division Multiplexing (ODFM) OFDM/ allows multiple users to transmit in an allocated band by dividing the bandwidth into many narrow bandwidth carriers. Power over Ethernet (PoE) A specification for providing both power and data to low-power network devices using a single Category 5 Ethernet cable. PoE provides greater flexibility in the locating of access point’s and network devices, and significantly decreased installation costs. Glossary-3 RADIUS A logon authentication protocol that uses software running on a central server to control access to the network. Roaming A wireless LAN mobile user moves around an ESS and maintains a continuous connection to the infrastructure network. RTS Threshold Transmitters contending for the medium may not be aware of each other. RTS/CTS mechanism can solve this “Hidden Node Problem.” If the packet size is smaller than the preset RTS Threshold size, the RTS/CTS mechanism will NOT be enabled. Service Set Identifier (SSID) An identifier that is attached to packets sent over the wireless LAN and functions as a password for joining a particular radio cell; i.e., Basic Service Set (BSS). Session Key Session keys are unique to each client, and are used to authenticate a client connection, and correlate traffic passing between a specific client and the access point. Shared Key A shared key can be used to authenticate each client attached to a wireless network. Shared Key authentication must be used along with the 802.11 Wireless Equivalent Privacy algorithm. Simple Network Management Protocol (SNMP) The application protocol in the Internet suite of protocols which offers network management services. Simple Network Time Protocol (SNTP) SNTP allows a device to set its internal clock based on periodic updates from a Network Time Protocol (NTP) server. Updates can be requested from a specific NTP server, or can be received via broadcasts sent by NTP servers. Temporal Key Integrity Protocol (TKIP) A data encryption method designed as a replacement for WEP. TKIP avoids the problems of WEP static keys by dynamically changing data encryption keys. Trivial File Transfer Protocol (TFTP) A TCP/IP protocol commonly used for software downloads. Virtual Access Point (VAP) Virtual AP technology multiplies the number of Access Points present within the RF footprint of a single physical access device. With Virtual AP technology, WLAN users within the device’s footprint can associate with what appears to be different access points and their associated Glossary-4 network services. All the services are delivered using a single radio channel, enabling Virtual AP technology to optimize the use of limited WLAN radio spectrum. Virtual LAN (VLAN) A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. A VLAN serves as a logical workgroup with no physical barriers, and allows users to share information and resources as though located on the same LAN. Wi-Fi Protected Access WPA employs 802.1X as its basic framework for user authentication and dynamic key management to provide an enhanced security solution for 802.11 wireless networks. Wired Equivalent Privacy (WEP) WEP is based on the use of security keys and the popular RC4 encryption algorithm. Wireless devices without a valid WEP key will be excluded from network traffic. WPA Pre-shared Key (PSK) PSK can be used for small office networks that may not have the resources to configure and maintain a RADIUS server, WPA provides a simple operating mode that uses just a pre-shared password for network access.

System Clock Commands Command Function Mode Page sntp-server ip Specifies one or more time servers GC 7-34 sntp-server enable Accepts time from the specified time servers GC 7-34 sntp-server date-time Manually sets the system date and time GC 7-35 sntp-server daylight-saving Sets the start and end dates for daylight savings time GC 7-36 sntp-server timezone Sets the time zone for the bridge’s internal clock GC 7-36 show sntp Shows current SNTP configuration settings Exec 7-37 7-33 7 Command Line Interface sntp-server ip This command sets the IP address of the servers to which SNTP time requests are issued. Use the this command with no arguments to clear all time servers from the current list. Syntax sntp-server ip <1 | 2> • 1 - First time server. • 2 - Second time server. • ip - IP address of an time server (NTP or SNTP). Default Setting 137.92.140.80 192.43.244.18 Command Mode Global Configuration Command Usage When SNTP client mode is enabled using the sntp-server enable command, the sntp-server ip command specifies the time servers from which the bridge polls for time updates. The bridge will poll the time servers in the order specified until a response is received. Example Enterprise AP(config)#sntp-server ip 10.1.0.19 Enterprise AP# Related Commands sntp-server enable (7-34) show sntp (7-37) sntp-server enable This command enables SNTP client requests for time synchronization with NTP or SNTP time servers specified by the sntp-server ip command. Use the no form to disable SNTP client requests. Syntax sntp-server enable no sntp-server enable Default Setting Enabled 7-34 System Clock Commands Command Mode Global Configuration Command Usage The time acquired from time servers is used to record accurate dates and times for log events. Without SNTP, the bridge only records the time starting from the factory default set at the last bootup (i.e., 00:14:00, January 1, 1970). Example Enterprise AP(config)#sntp-server enable Enterprise AP(config)# Related Commands sntp-server ip (7-34) show sntp (7-37) sntp-server date-time This command sets the system clock. Default Setting 00:14:00, January 1, 1970 Command Mode Global Configuration Example This example sets the system clock to 17:37 June 19, 2003. Enterprise AP#sntp-server date-time Enter Year<1970-2100>: 2003 Enter Month<1-12>: 6 Enter Day<1-31>: 19 Enter Hour<0-23>: 17 Enter Min<0-59>: 37 Enterprise AP# Related Commands sntp-server enable (7-34) 7-35 7 Command Line Interface sntp-server daylight-saving This command sets the start and end dates for daylight savings time. Use the no form to disable daylight savings time. Syntax sntp-server daylight-saving no sntp-server daylight-saving Default Setting Disabled Command Mode Global Configuration Command Usage The command sets the system clock back one hour during the specified period. Example This sets daylight savings time to be used from July 1st to September 1st. Enterprise AP(config)#sntp-server daylight-saving Enter Daylight saving from which month<1-12>: 6 and which day<1-31>: 1 Enter Daylight saving end to which month<1-12>: 9 and which day<1-31>: 1 Enterprise AP(config)# sntp-server timezone This command sets the time zone for the bridge’s internal clock. Syntax sntp-server timezone hours - Number of hours before/after UTC. (Range: -12 to +12 hours) Default Setting -5 (BOGOTA, EASTERN, INDIANA) Command Mode Global Configuration 7-36 System Clock Commands Command Usage This command sets the local time zone relative to the Coordinated Universal Time (UTC, formerly Greenwich Mean Time or GMT), based on the earth’s prime meridian, zero degrees longitude. To display a time corresponding to your local time, you must indicate the number of hours and minutes your time zone is east (before) or west (after) of UTC. Example Enterprise AP(config)#sntp-server timezone +8 Enterprise AP(config)# show sntp This command displays the current time and configuration settings for the SNTP client. Command Mode Exec Example Enterprise AP#show sntp SNTP Information ========================================================= Service State : Enabled SNTP (server 1) IP : 137.92.140.80 SNTP (server 2) IP : 192.43.244.18 Current Time : 08 : 04, Jun 20th, 2003 Time Zone : +8 (TAIPEI, BEIJING) Daylight Saving : Enabled, from Jun, 1st to Sep, 1st ========================================================= Enterprise AP# 7-37 7 Command Line Interface DHCP Relay Commands Dynamic 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 bridge’s DHCP relay agent is enabled, received client requests can be forwarded directly by the bridge to a known DHCP server on another subnet. Responses from the DHCP server are returned to the bridge, which then broadcasts them back to clients. Table 7-8. DHCP Relay Commands Command Function Mode dhcp-relay enable Enables the DHCP relay agent GC Page 7-38 dhcp-relay Sets the primary and secondary DHCP server address GC 7-39 show dhcp-relay Shows current DHCP relay configuration settings Exec 7-39 dhcp-relay enable This command enables the bridge’s DHCP relay agent. Use the no form to disable the agent. Syntax [no] dhcp-relay enable Default Setting Disabled Command Mode Global Configuration Command 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 Enterprise AP(config)#dhcp-relay enable Enterprise AP(config)# 7-38 DHCP Relay Commands dhcp-relay This command configures the primary and secondary DHCP server addresses. Syntax dhcp-relay • primary - The primary DHCP server. • secondary - The secondary DHCP server. • ip_address - IP address of the server. Default Setting Primary and secondary: 0.0.0.0 Command Mode Global Configuration Example Enterprise AP(config)#dhcp-relay primary 192.168.1.10 Enterprise AP(config)# show dhcp-relay This command displays the current DHCP relay configuration. Command Mode Exec Example Enterprise AP#show dhcp-relay DHCP Relay : ENABLED Primary DHCP Server : 192.168.1.10 Secondary DHCP Server : 0.0.0.0 Enterprise AP# 7-39 7 Command Line Interface SNMP Commands Controls access to this bridge from management stations using the Simple Network Management Protocol (SNMP), as well as the hosts that will receive trap messages.

(Range: 1-63 characters) community-string - Password-like community string sent with the notification operation. Although you can set this string using the snmp-server host command by itself, we recommend that you define this string using the snmp-server community command prior to using the snmp-server host command. (Maximum length: 23 characters) Default Setting Host Address: None Community String: public Command Mode Global Configuration 7-43 7 Command Line Interface Command Usage The snmp-server host command is used in conjunction with the snmp-server enable server command to enable SNMP notifications. Example Enterprise AP(config)#snmp-server host 1 10.1.19.23 batman Enterprise AP(config)# Related Commands snmp-server enable server (7-42) snmp-server trap This command enables the bridge to send specific SNMP traps (i.e., notifications). Use the no form to disable specific trap messages. Syntax snmp-server trap no snmp-server trap • trap - One of the following SNMP trap messages: - dot11InterfaceAGFail - The 802.11a or 802.11g interface has failed. - dot11InterfaceBFail - The 802.11b interface has failed. - dot11StationAssociation - A client station has successfully associated with the bridge. - dot11StationAuthentication - A client station has been successfully authenticated. - dot11StationReAssociation - A client station has successfully re-associated with the bridge. - dot11StationRequestFail - A client station has failed association, re-association, or authentication. - dot1xAuthFail - A 802.1X client station has failed RADIUS authentication. - dot1xAuthNotInitiated - A client station did not initiate 802.1X authentication. - dot1xAuthSuccess - A 802.1X client station has been successfully authenticated by the RADIUS server. - dot1xMacAddrAuthFail - A client station has failed MAC address authentication with the RADIUS server. - dot1xMacAddrAuthSuccess - A client station has successfully authenticated its MAC address with the RADIUS server. - iappContextDataSent - A client station’s Context Data has been sent to another bridge with which the station has associated. - iappStationRoamedFrom - A client station has roamed from another bridge (identified by its IP address). 7-44 SNMP Commands - iappStationRoamedTo - A client station has roamed to another bridge (identified by its IP address). - localMacAddrAuthFail - A client station has failed authentication with the local MAC address database on the bridge. - localMacAddrAuthSuccess - A client station has successfully authenticated its MAC address with the local database on the bridge. - pppLogonFail - The bridge has failed to log onto the PPPoE server using the configured user name and password. - sntpServerFail - The bridge has failed to set the time from the configured SNTP server. - sysConfigFileVersionChanged - The bridge’s configuration file has been changed. - sysRadiusServerChanged - The bridge has changed from the primary RADIUS server to the secondary, or from the secondary to the primary. - sysSystemDown - The bridge is about to shutdown and reboot. - sysSystemUp - The bridge is up and running. Default Setting All traps enabled Command Mode Global Configuration Command Usage This command is used in conjunction with the snmp-server host and snmp-server enable server commands to enable SNMP notifications. Example Enterprise AP(config)#no snmp-server trap dot11StationAssociation Enterprise AP(config)# snmp-server engine-id This command is used for SNMP v3. It is used to uniquely identify the bridge among all bridges in the network. Use the no form to delete the engine ID. Syntax snmp-server engine-id no snmp-server engine-id engine-id - Enter engine-id in hexadecimal (5-32 characters). Default Setting Enabled 7-45 7 Command Line Interface Command Mode Global Configuration Command Usage • This command is used in conjunction with the snmp-server user command. • Entering this command invalidates all engine IDs that have been previously configured. • If the engineID is deleted or changed, all SNMP users will be cleared. You will need to reconfigure all existing users Example Enterprise AP(config)#snmp-server engine-id 1a:2b:3c:4d:00:ff Enterprise AP(config)# snmp-server user This command configures the SNMP v3 users that are allowed to manage the bridge. Use the no form to delete an SNMP v3 user. Syntax snmp-server user user-name - A user-defined string for the SNMP user. (32 characters maximum) Default Setting None Command Mode Global Configuration Command Usage • Up to 10 SNMPv3 users can be configured on the bridge. • The SNMP engine ID is used to compute the authentication/privacy digests from the pass phrase. You should therefore configure the engine ID with the snmp-server engine-id command before using this configuration command. • The bridge 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. 7-46 SNMP Commands • • • • - 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) - group-name - The name of the SNMP group to which the user is assigned (32 characters maximum). There are three pre-defined groups: RO, RWAuth, or RWPriv. - auth-proto - The authentication type used for user authentication: md5 or none. - auth-passphrase - The user password required when authentication is used (8 – 32 characters). - priv-proto - The encryption type used for SNMP data encryption: des or none. - priv-passphrase - The user password required when data encryption is used (8 – 32 characters). Users must be assigned to groups that have the same security levels. If a user who has “AuthPriv” security (uses authentication and encryption) is assigned to a read-only (RO) group, the user will not be able to access the database. An AuthPriv user must be assigned to the RWPriv group with the AuthPriv security level. To configure a user for the RWAuth group, you must include the auth-proto and auth-passphrase keywords. To configure a user for the RWPriv group, you must include the auth-proto, auth-passphrase, priv-proto, and priv-passphrase keywords. Example Enterprise AP(config)#snmp-server user User Name<1-32> :chris Group Name<1-32> :RWPriv Authtype(md5,none):md5 Passphrase<8-32>:a good secret Privacy(des,none) :des Passphrase<8-32>:a very good secret Enterprise AP(config)# 7-47 7 Command Line Interface snmp-server targets This command configures SNMP v3 notification targets. Use the no form to delete an SNMP v3 target. Syntax snmp-server targets [version {3}] [udp-port {port-number}] [notification-type {TRAP}] no snmp-server targets • target-id - A user-defined name that identifies a receiver of SNMP notifications. (Maximum length: 32 characters) • ip-addr - Specifies the IP address of the management station to receive notifications. • sec-name - The defined SNMP v3 user name that is to receive notifications. • version - The SNMP version of notifications. Currently only version 3 is supported in this command. • udp-port - The UDP port that is used on the receiving management station for notifications. • notification-type - The type of notification that is sent. Currently only TRAP is supported. Default Setting None Command Mode Global Configuration Command Usage • The bridge supports up to 10 SNMP v3 target IDs. • The SNMP v3 user name that is specified in the target must first be configured using the snmp-server user command. Example Enterprise AP(config)#snmp-server targets mytraps 192.168.1.33 chris Enterprise AP(config)# 7-48 SNMP Commands snmp-server filter This command configures SNMP v3 notification filters. Use the no form to delete an SNMP v3 filter or remove a subtree from a filter. Syntax snmp-server filter [mask {mask}] no snmp-server filter [subtree] • filter-id - A user-defined name that identifies an SNMP v3 notification filter. (Maximum length: 32 characters) • include - Defines a filter type that includes objects in the MIB subtree. • exclude - Defines a filter type that excludes objects in the MIB subtree. • subtree - The part of the MIB subtree that is to be filtered. • mask - An optional hexadecimal value bit mask to define objects in the MIB subtree. Default Setting None Command Mode Global Configuration Command Usage • The bridge allows up to 10 notification filters to be created. Each filter can be defined by up to 20 MIB subtree ID entries. • Use the command more than once with the same filter ID to build a filter that includes or excludes multiple MIB objects. Note that the filter entries are applied in the sequence that they are defined. • The MIB subtree must be defined in the form “.1.3.6.1” and always start with a “.”. • The mask is a hexadecimal value with each bit masking the corresponding ID in the MIB subtree. A “1” in the mask indicates an exact match and a “0” indicates a “wild card.” For example, a mask value of 0xFFBF provides a bit mask “1111 1111 1011 1111.” If applied to the subtree 1.3.6.1.2.1.2.2.1.1.23, the zero corresponds to the 10th subtree ID. When there are more subtree IDs than bits in the mask, the mask is padded with ones. Example Enterprise AP(config)#snmp-server filter trapfilter include .1 Enterprise AP(config)#snmp-server filter trapfilter exclude .1.3.6.1.2.1.2.2.1.1.23 7-49 7 Command Line Interface snmp-server filter-assignments This command assigns SNMP v3 notification filters to targets. Use the no form to remove an SNMP v3 filter assignment. Syntax snmp-server filter-assignments no snmp-server filter-assignments • target-id - A user-defined name that identifies a receiver of SNMP notifications. (Maximum length: 32 characters) • filter-id - A user-defined name that identifies an SNMP v3 notification filter. (Maximum length: 32 characters) Default Setting None Command Mode Global Configuration Example Enterprise AP(config)#snmp-server filter-assignments mytraps trapfilter Enterprise AP(config)#exit Enterprise AP#show snmp target Host ID : mytraps User : chris IP Address : 192.168.1.33 UDP Port : 162 ============================= Enterprise AP#show snmp filter-assignments HostID mytraps FilterID trapfilter Enterprise AP(config)# show snmp groups This command displays the SNMP v3 pre-defined groups.

This control feature prevents unauthorized access to the network by requiring an 802.1X client application to submit user credentials for authentication. Client authentication is then verified by a RADIUS server using EAP (Extensible Authentication Protocol) before the bridge grants client access to the network. The 802.1X EAP packets are also used to pass dynamic unicast session keys and static broadcast keys to wireless clients. Table 7-12. 802.1X Authentication Command Function Mode Page 802.1x Configures 802.1X as disabled, supported, or required IC-W-VAP 7-65 802.1x broadcast-keyrefresh-rate Sets the interval at which the primary broadcast keys are IC-W-VAP refreshed for stations using 802.1X dynamic keying 7-66 802.1x session-keyrefresh-rate Sets the interval at which unicast session keys are IC-W-VAP refreshed for associated stations using dynamic keying 7-67 802.1x session-timeout Sets the timeout after which a connected client must be IC-W-VAP re-authenticated 7-67 802.1x-supplicant enable Enables the bridge to operate as a 802.1X supplicant GC 7-68 802.1x-supplicant user Sets the supplicant user name and password for the bridge GC 7-68 show authentication Shows all 802.1X authentication settings, as well as the Exec address filter table 7-68 802.1x This command configures 802.1X as optionally supported or as required for wireless clients. Use the no form to disable 802.1X support. Syntax 802.1x no 802.1x • supported - Authenticates clients that initiate the 802.1X authentication process. Uses standard 802.11 authentication for all others. • required - Requires 802.1X authentication for all clients. Default Setting Disabled 7-65 7 Command Line Interface Command Mode Global Configuration Command Usage • When 802.1X is disabled, the bridge does not support 802.1X authentication for any station. After successful 802.11 association, each client is allowed to access the network. • When 802.1X is supported, the bridge supports 802.1X authentication only for clients initiating the 802.1X authentication process (i.e., the bridge does NOT initiate 802.1X authentication). For stations initiating 802.1X, only those stations successfully authenticated are allowed to access the network. For those stations not initiating 802.1X, access to the network is allowed after successful 802.11 association. • When 802.1X is required, the bridge enforces 802.1X authentication for all 802.11 associated stations. If 802.1X authentication is not initiated by the station, the bridge will initiate authentication. Only those stations successfully authenticated with 802.1X are allowed to access the network. • 802.1X does not apply to the 10/100Base-TX port. Example Enterprise AP(config)#802.1x supported Enterprise AP(config)# 802.1x broadcast-key-refresh-rate This command sets the interval at which the broadcast keys are refreshed for stations using 802.1X dynamic keying. Syntax 802.1x broadcast-key-refresh-rate rate - The interval at which the bridge rotates broadcast keys. (Range: 0 1440 minutes) Default Setting 0 (Disabled) Command Mode Global Configuration Command Usage • The bridge uses Enterprise APOL (Extensible Authentication Protocol Over LANs) packets to pass dynamic unicast session and broadcast keys to wireless clients. The 802.1x broadcast-key-refresh-rate command specifies the interval after which the broadcast keys are changed. The 802.1x session-key-refresh-rate command specifies the interval after which unicast session keys are changed. 7-66 802.1X Authentication • Dynamic broadcast key rotation allows the bridge to generate a random group key and periodically update all key-management capable wireless clients.

Syntax bridge role • ap - Operates only as an bridge 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 bridges also in bridge mode. • root-bridge - Operates as the root bridge in the wireless bridge network. Default Setting AP Command 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 7-78). When the bridge 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-bridge Enterprise AP(if-wireless a)# bridge-link parent This command configures the MAC address of the parent bridge node.

Enterprise AP(config)bridge stp enable Enterprise AP(config) 7-83 7 Command Line Interface bridge stp forwarding-delay Use this command to configure the spanning tree bridge forward time globally for the wireless bridge. Use the no form to restore the default. Syntax bridge stp forwarding-delay no bridge stp forwarding-delay seconds - Time in seconds. (Range: 4 - 30 seconds) The minimum value is the higher of 4 or [(max-age / 2) + 1]. Default Setting 15 seconds Command Mode Global Configuration Command 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 Enterprise AP(config)#bridge stp forwarding-delay 20 Enterprise AP(config)# bridge stp hello-time Use 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 • a - 802.11a radio interface. • g - 802.11g radio interface. 7-94 Wireless Interface Commands Default Setting None Command Mode Global Configuration Example To specify the 802.11a interface, enter the following command: Enterprise AP(config)#interface wireless a Enterprise AP(if-wireless a)# vap This command provides access to the VAP (Virtual bridge) interface configuration mode. Syntax vap vap-id - The number that identifies the VAP interface. (Options: 0-7) Default Setting None Command Mode Interface Configuration (Wireless) Example Enterprise AP(if-wireless g)#vap 0 Enterprise AP(if-wireless g: VAP[0])# speed This command configures the maximum data rate at which the bridge transmits unicast packets. Syntax speed speed - Maximum access speed allowed for wireless clients. (Options for 802.11a: 6, 9, 12, 18, 24, 36, 48, 54 Mbps) (Options for 802.11b/g: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps) 7-95 7 Command Line Interface Default Setting 54 Mbps Command Mode Interface Configuration (Wireless) Command Usage • The maximum transmission distance is affected by the data rate. The lower the data rate, the longer the transmission distance. Please refer to the table for maximum distances on page -6. • When turbo mode is enabled (page 7-107) for 802.11a, the effective maximum speed specified by this command is double the entered value (e.g., setting the speed to 54 Mbps limits the effective maximum speed to 108 Mbps). Example Enterprise AP(if-wireless g)#speed 6 Enterprise AP(if-wireless g)# turbo This command sets the bridge to an enhanced proprietary modulation mode (not regulated in IEEE 802.11a) that provides a higher data rate of up to 108 Mbps. Syntax turbo no turbo static - Always uses turbo mode. dynamic - Will use turbo mode when no other nearby bridges are detected or active. Default Setting Disabled Command Mode Interface Configuration (Wireless - 802.11a) Command Usage • 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 bridge to provide connections up to 108 Mbps. • In normal mode, the bridge provides a channel bandwidth of 20 MHz, and supports the maximum number of channels permitted by local regulations (e.g., 11 channels for the United States). In Turbo Mode, the channel bandwidth is increased to 40 MHz to support the increased data rate. 7-96 Wireless Interface Commands However, this reduces the number of channels supported (e.g., 5 channels for the United States). Example Enterprise AP(if-wireless a)#turbo Enterprise AP(if-wireless a)# multicast-data-rate This command configures the maximum data rate at which the bridge transmits multicast and management packets (excluding beacon packets) on the wireless interface. Syntax multicast-data-rate speed - Maximum transmit speed allowed for multicast data. (Options for 802.11a: 6, 12, 24 Mbps) (Options for 802.11b/g; 1, 2, 5.5, 11 Mbps) Default Setting 1 Mbps for 802.11b/g 6 Mbps for 802.11a Command Mode Interface Configuration (Wireless) Example Enterprise AP(if-wireless g)#multicast-data-rate 5.5 Enterprise AP(if-wireless g)# 7-97 7 Command Line Interface channel This command configures the radio channel through which the bridge communicates with wireless clients. Syntax channel • channel - Manually sets the radio channel used for communications with wireless clients. (Range for 802.11a: 36, 40, 44, 48, 52, 56, 60, 64, 149, 153, 157, 161, 165 for normal mode, and 42, 50, 58, 152, 160 for turbo mode; Range for 802.11b/g: 1 to 14) • auto - Automatically selects an unoccupied channel (if available). Otherwise, the lowest channel is selected. Default Setting Automatic channel selection Command Mode Interface Configuration (Wireless) Command Usage • The available channel settings are limited by local regulations, which determine the number of channels that are available. • When multiple bridges are deployed in the same area, be sure to choose a channel separated by at least two channels for 802.11a to avoid having the channels interfere with each other, and at least five channels for 802.11b/ g. You can deploy up to four bridges in the same area for 802.11a (e.g., channels 36, 56, 149, 165) and three bridges for 802.11b/g (e.g., channels 1, 6, 11). • For most wireless adapters, the channel for wireless clients is automatically set to the same as that used by the bridge to which it is linked. Example Enterprise AP(if-wireless g)#channel 1 Enterprise AP(if-wireless g)# transmit-power This command adjusts the power of the radio signals transmitted from the bridge. Syntax transmit-power signal-strength - Signal strength transmitted from the bridge. (Options: full, half, quarter, eighth, min) 7-98 Wireless Interface Commands Default Setting full Command Mode Interface Configuration (Wireless) Command Usage • The “min” keyword indicates minimum power. • The longer the transmission distance, the higher the transmission power required. 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 Enterprise AP(if-wireless g)#transmit-power half Enterprise AP(if-wireless g)# radio-mode This command forces the operating mode for the 802.11g wireless interface. Syntax radio-mode • b - b-only mode: Both 802.11b and 802.11g clients can communicate with the bridge, 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 bridge (up to 54 Mbps). • b+g - b & g mixed mode: Both 802.11b and 802.11g clients can communicate with the bridge (up to 54 Mbps). Default Setting b+g mode Command Mode Interface Configuration (Wireless - 802.11g) Command Usage • For Japan, only 13 channels are available when set to g or b+g modes. When set to b mode, 14 channels are available. • Both the 802.11g and 802.11b standards operate within the 2.4 GHz band. If you are operating in g mode, any 802.11b devices in the service area will contribute to the radio frequency noise and affect network performance. 7-99 7 Command Line Interface Example Enterprise AP(if-wireless g)#radio-mode g Enterprise AP(if-wireless g)# preamble This command sets the length of the signal preamble that is used at the start of a 802.11b/g data transmission. Syntax preamble [long | short-or-long] • long - Sets the preamble to long (192 microseconds). • short-or-long - Sets the preamble to short if no 802.11b clients are detected (96 microseconds). Default Setting Short-or-Long Command Mode Interface Configuration (Wireless - 802.11b/g) Command Usage • Using a short preamble instead of a long preamble can increase data throughput on the bridge, but requires that all clients can support a short preamble. • Set the preamble to long to ensure the bridge can support all 802.11b and 802.11g clients. Example Enterprise AP(if-wireless g)#preamble short Enterprise AP(if-wireless g)# antenna control This command selects the use of two diversity antennas or a single antenna for the radio interface. Syntax antenna control • 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 bridge's integrated antennas. The bridge does not support external diversity antennas. • left - The radio only uses the antenna on the left side (the side farthest from the bridge LEDs). The bridge does not support an external antenna connection on its left antenna. Therefore, this method is not valid for the bridge. 7-100 Wireless Interface Commands • right - The radio only uses the antenna on the right side (the side closest to the bridge LEDs). Select this method when using an optional external antenna that is connected to the right antenna connector. Default Setting Diversity Command Mode Interface Configuration (Wireless) Command Usage The antenna ID must be selected in conjunction with the antenna control method to configure proper use of any of the antenna options. Example Enterprise AP(if-wireless g)#antenna control right Enterprise AP(if-wireless g)# antenna id This command specifies the antenna type connected to the bridge represented by a four-digit hexadecimal ID number, either the integrated diversity antennas (the "Default Antenna") or an optional external antenna. Syntax antenna id • antenna-id - Specifies the ID number of an approved antenna that is connected to the bridge (Range: 0x0000 - 0xFFFF) Default Setting 0x0000 (built-in antennas) Command Mode Interface Configuration (Wireless) Command Usage • The optional external antennas (if any) that are certified for use with the bridge are listed by typing antenna control id ?. Selecting the correct antenna ID ensures that the bridge's radio transmissions are within regulatory power limits for the country of operation. • The antenna ID must be selected in conjunction with the antenna control method to configure proper use of any of the antenna options. Example Enterprise AP(if-wireless g)#antenna id 0000 Enterprise AP(if-wireless g)# 7-101 7 Command Line Interface antenna location This command selects the antenna mounting location for the radio interface. Syntax antenna location • indoor - The antenna is mounted indoors. • outdoor - The antenna is mounted outdoors. Default Setting Indoor Command Mode Interface Configuration (Wireless) Command Usage • When an external antenna is selected, the antenna control must be set to “right.” • Selecting the correct location ensures that the bridge only uses radio channels that are permitted in the country of operation. Example Enterprise AP(if-wireless g)#antenna location indoor Enterprise AP(if-wireless g)# beacon-interval This command configures the rate at which beacon signals are transmitted from the bridge. Syntax beacon-interval interval - The rate for transmitting beacon signals. (Range: 20-1000 milliseconds) Default Setting 100 Command Mode Interface Configuration (Wireless) Command Usage The beacon signals allow wireless clients to maintain contact with the bridge. They may also carry power-management information. 7-102 Wireless Interface Commands Example Enterprise AP(if-wireless g)#beacon-interval 150 Enterprise AP(if-wireless g)# dtim-period This command configures the rate at which stations in sleep mode must wake up to receive broadcast/multicast transmissions. Syntax dtim-period interval - Interval between the beacon frames that transmit broadcast or multicast traffic. (Range: 1-255 beacon frames) Default Setting Command 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 bridge 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. Example Enterprise AP(if-wireless g)#dtim-period 100 Enterprise AP(if-wireless g)# 7-103 7 Command Line Interface fragmentation-length This command configures the minimum packet size that can be fragmented when passing through the bridge. Syntax fragmentation-length length - Minimum packet size for which fragmentation is allowed. (Range: 256-2346 bytes) Default Setting 2346 Command 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. Example Enterprise AP(if-wireless g)#fragmentation-length 512 Enterprise AP(if-wireless g)# rts-threshold This 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. Syntax rts-threshold threshold - Threshold packet size for which to send an RTS. (Range: 0-2347 bytes) 7-104 Wireless Interface Commands Default Setting 2347 Command Mode Interface Configuration (Wireless) Command Usage • If the threshold is set to 0, the bridge always sends RTS signals. If set to 2347, the bridge 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 bridge 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. • bridges contending for the wireless medium may not be aware of each other. The RTS/CTS mechanism can solve this “Hidden Node” problem. Example Enterprise AP(if-wireless g)#rts-threshold 256 Enterprise AP(if-wireless g)# super-a This command enables Atheros proprietary Super A performance enhancements. Use the no form to disable this function. Syntax [no] super-a Default Setting Disabled Command Mode Interface Configuration (Wireless - 802.11a) Command Usage Super A enhancements include bursting, compression, and fast frames. Maximum throughput ranges between 40 to 60 Mbps for connections to Atheros-compatible clients. Example Enterprise AP(if-wireless a)#super a Enterprise AP(if-wireless a)# 7-105 7 Command Line Interface super-g This command enables Atheros proprietary Super G performance enhancements. Use the no form to disable this function. Syntax [no] super-g Default Setting Disabled Command Mode Interface Configuration (Wireless - 802.11g) Command Usage These enhancements include bursting, compression, fast frames and dynamic turbo. Maximum throughput ranges between 40 to 60 Mbps for connections to Atheros-compatible clients. Example Enterprise AP(if-wireless a)#super g Enterprise AP(if-wireless a)# description This command adds a description to a the wireless interface. Use the no form to remove the description. Syntax description no description string - Comment or a description for this interface. (Range: 1-80 characters) Default Setting None Command Mode Interface Configuration (Wireless-VAP) Example Enterprise AP(if-wireless g: VAP[0])#description RD-AP#3 Enterprise AP(if-wireless g: VAP[0])# 7-106 Wireless Interface Commands ssid This command configures the service set identifier (SSID). Syntax ssid string - The name of a basic service set supported by the bridge. (Range: 1 - 32 characters) Default Setting 802.11a Radio: VAP_TEST_11A (0 to 3) 802.11g Radio: VAP_TEST_11G (0 to 3) Command Mode Interface Configuration (Wireless-VAP) Command Usage Clients that want to connect to the wireless network via an bridge must set their SSIDs to the same as that of the bridge. Example Enterprise AP(if-wireless g: VAP[0])#ssid RD-AP#3 Enterprise AP(if-wireless g)# closed-system This command prohibits access to clients without a pre-configured SSID. Use the no form to disable this feature. Syntax closed-system no closed-system Default Setting Disabled Command Mode Interface Configuration (Wireless-VAP) Command Usage When closed system is enabled, the bridge will not include its SSID in beacon messages. Nor will it respond to probe requests from clients that do not include a fixed SSID. Example Enterprise AP(if-wireless g: VAP[0])#closed-system Enterprise AP(if-wireless g)# 7-107 7 Command Line Interface max-association This command configures the maximum number of clients that can be associated with the bridge at the same time. Syntax max-association count - Maximum number of associated stations. (Range: 0-64) Default Setting 64 Command Mode Interface Configuration (Wireless-VAP) Example Enterprise AP(if-wireless g: VAP[0])#max-association 32 Enterprise AP(if-wireless g)# assoc-timeout-interval This command configures the idle time interval (when no frames are sent) after which the client is disassociated from the VAP interface. Syntax assoc-timeout-interval minutes - The number of minutes of inactivity before disassociation. (Range: 5-60) Default Setting 30 Command Mode Interface Configuration (Wireless-VAP) Example Enterprise AP(if-wireless g: VAP[0])#association-timeout-interval 20 Enterprise AP(if-wireless g: VAP[0])# auth-timeout-value This command configures the time interval within which clients must complete authentication to the VAP interface. Syntax auth-timeout-value minutes - The number of minutes before re-authentication. (Range: 5-60) 7-108 Wireless Interface Commands Default Setting 60 Command Mode Interface Configuration (Wireless-VAP) Example Enterprise AP(if-wireless g: VAP[0])#auth-timeout-value 40 Enterprise AP(if-wireless g: VAP[0])# shutdown This command disables the wireless interface. Use the no form to restart the interface. Syntax shutdown no shutdown Default Setting Interface enabled Command Mode Interface Configuration (Wireless-VAP) Command Usage You must first enable VAP interface 0 before you can enable VAP interfaces 1, 2, 3, 4, 5, 6, or 7. Example Enterprise AP(if-wireless g: VAP[0])#shutdown Enterprise AP(if-wireless g)# 7-109 7 Command Line Interface show interface wireless This command displays the status for the wireless interface.

Enterprise AP# 7-112 Rogue AP Detection Commands Rogue AP Detection Commands A “rogue AP” is either an bridge that is not authorized to participate in the wireless network, or an bridge that does not have the correct security configuration. Rogue APs can potentially allow unauthorized users access to the network. Alternatively, client stations may mistakenly associate to a rogue AP and be prevented from accessing network resources. Rogue APs may also cause radio interference and degrade the wireless LAN performance. The bridge can be configured to periodically scan all radio channels and find other bridges within range. A database of nearby bridges is maintained where any rogue APs can be identified. Table 7-18. Rogue AP Detection Commands Command Function Mode Page rogue-ap enable Enables the periodic detection of other nearby bridges GC 7-113 rogue-ap authenticate Enables identification of all bridges GC 7-114 rogue-ap duration Sets the duration that all channels are scanned GC 7-114 rogue-ap interval Sets the time between each scan GC 7-115 rogue-ap scan Forces an immediate scan of all radio channels GC 7-116 show rogue-ap Shows the current database of detected bridges Exec 7-117 rogue-ap enable This command enables the periodic detection of nearby bridges. Use the no form to disable periodic detection. Syntax [no] rogue-ap enable Default Setting Disabled Command Mode Interface Configuration (Wireless) Command Usage • While the bridge scans a channel for rogue APs, wireless clients will not be able to connect to the bridge. 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. 7-113 7 Command Line Interface • A “rogue AP” is either an bridge that is not authorized to participate in the wireless network, or an bridge that does not have the correct security configuration. Rogue bridges can be identified by unknown BSSID (MAC address) or SSID configuration. A database of nearby bridges should therefore be maintained on a RADIUS server, allowing any rogue APs to be identified (see “rogue-ap authenticate” on page 7-114). The rogue AP database can be viewed using the show rogue-ap command. • The bridge sends Syslog messages for each detected bridge during a rogue AP scan. Example Enterprise AP(if-wireless g)#rogue-ap enable configure either syslog or trap or both to receive the rogue APs detected. Enterprise AP(if-wireless g)# rogue-ap authenticate This command forces the unit to authenticate all bridges on the network. Use the no form to disable this function. Syntax [no] rogue-ap authenticate Default Setting Disabled Command Mode Interface Configuration (Wireless) Command Usage Enabling authentication in conjunction with a database of approved bridges stored on a RADIUS server allows the bridge to discover rogue APs. With authentication enabled and a configure RADIUS server, the bridge checks the MAC address/Basic Service Set Identifier (BSSID) of each bridge that it finds against a RADIUS server to determine whether the bridge is allowed. With authentication disabled, the bridge can identify its neighboring bridges only; it cannot identify whether the bridges are allowed or are rogues. If you enable authentication, you should also configure a RADIUS server for this bridge (see “Radius” on page 6-7). Example Enterprise AP(if-wireless g)#rogue-ap authenticate Enterprise AP(if-wireless g)# rogue-ap duration This command sets the scan duration for detecting bridges. 7-114 Rogue AP Detection Commands 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 bridge. If clients experience severe disruption, reduce the scan duration time. • A long scan duration time will detect more bridges in the area, but causes more disruption to client access. Example Enterprise AP(if-wireless g)#rogue-ap duration 200 Enterprise AP(if-wireless g)# Related Commands rogue-ap interval (7-115) rogue-ap interval This command sets the interval at which to scan for bridges. Syntax rogue-ap interval minutes - The interval between consecutive scans. (Range: 30-10080 minutes) Default Setting 720 minutes Command Mode Interface Configuration (Wireless) Command Usage This command sets the interval at which scans occur. Frequent scanning will more readily detect other bridges, but will cause more disruption to client access. 7-115 7 Command Line Interface Example Enterprise AP(if-wireless g)#rogue-ap interval 120 Enterprise AP(if-wireless g)# Related Commands rogue-ap duration (7-114) rogue-ap scan This command starts an immediate scan for bridges on the radio interface. Default Setting Disabled Command Mode Interface Configuration (Wireless) Command Usage While the bridge scans a channel for rogue APs, wireless clients will not be able to connect to the bridge. 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.

Syntax auth • open-system - Accepts the client without verifying its identity using a shared key. “Open” authentication means either there is no encryption (if encryption is disabled) or WEP-only encryption is used (if encryption is enabled). • shared-key - Authentication is based on a shared key that has been distributed to all stations. • wpa - Clients using WPA are accepted for authentication. • wpa-psk - Clients using WPA with a Pre-shared Key are accepted for authentication. • wpa2 - Clients using WPA2 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 are accepted for authentication. • wpa-wpa2-psk-mixed - Clients using WPA or WPA2 with a Pre-shared Key are accepted for authentication • required - Clients are required to use WPA or WPA2. • supported - Clients may use WPA or WPA2, if supported. Default Setting open-system Command Mode Interface Configuration (Wireless-VAP) Command Usage • The auth command automatically configures settings for each authentication type, including encryption, 802.1X, and cipher suite. The command auth open-system disables encryption and 802.1X. 7-118 Wireless Security Commands • 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 7-65) and RADIUS server details (see “RADIUS Client” on page 7-59) must be configured on the bridge. 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 7-65) and RADIUS server details (see “RADIUS Client” on page 7-59) 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 bridge. Use the wpa-preshared-key command to configure the key (see “key” on page 7-121 and “transmit-key” on page 7-122). • 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 bridge 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 bridge. 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 WEP). To place the VAP into AES only mode, use “required” and then select the “cipher-ccmp” option for the cipher-suite command. 7-119 7 Command Line Interface Example Enterprise AP(if-wireless g: VAP[0])#auth shared-key Enterprise AP(if-wireless g)# Related Commands encryption (7-120) key (7-121) encryption This command enables data encryption for wireless communications. Use the no form to disable data encryption. Syntax encryption no encryption Default Setting disabled Command Mode Interface Configuration (Wireless-VAP) Command Usage • Wired Equivalent Privacy (WEP) is implemented in this device to prevent unauthorized access to your wireless network. For more secure data transmissions, enable encryption with this command, and set at least one static WEP key with the key command. • The WEP settings must be the same on each client in your wireless network. • Note that WEP protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet. • You must enable data encryption in order to enable all types of encryption (WEP, TKIP, and AES-CCMP) in the bridge. Example Enterprise AP(if-wireless g: VAP[0])#encryption Enterprise AP(if-wireless g)# Related Commands key (7-121) 7-120 Wireless Security Commands key This command sets the keys used for WEP encryption. Use the no form to delete a configured key. Syntax key no key index • • • • index - Key index. (Range: 1-4) size - Key size. (Options: 64, 128, or 152 bits) type - Input format.

Default Setting None Command Mode Interface Configuration (Wireless) Command Usage • To enable Wired Equivalent Privacy (WEP), use the auth shared-key command to select the “shared key” authentication type, use the key command to configure at least one key, and use the transmit-key command to assign a key to one of the VAP interfaces. • If WEP option is enabled, all wireless clients must be configured with the same shared keys to communicate with the bridge. • The encryption index, length and type configured in the bridge must match those configured in the clients. Example Enterprise Enterprise Enterprise Enterprise AP(if-wireless AP(if-wireless AP(if-wireless AP(if-wireless g)#key 1 64 hex 1234512345 g)#key 2 128 ascii asdeipadjsipd g)#key 3 64 hex 12345123451234512345123456 g)# Related Commands key (7-121) encryption (7-120) transmit-key (7-122) 7-121 7 Command Line Interface transmit-key This command sets the index of the key to be used for encrypting data frames for broadcast or multicast traffic transmitted from the VAP to wireless clients. Syntax transmit-key index - Key index. (Range: 1-4) Default Setting Command Mode Interface Configuration (Wireless-VAP) Command Usage • If you use WEP key encryption option, the bridge uses the transmit key to encrypt multicast and broadcast data signals that it sends to client devices. Other keys can be used for decryption of data from clients. • When using IEEE 802.1X, the bridge uses a dynamic key to encrypt unicast and broadcast messages to 802.1X-enabled clients. However, because the bridge 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 bridge uses transmit key index 1 for the generation of dynamic keys. Example Enterprise AP(if-wireless g: VAP[0])#transmit-key 2 Enterprise AP(if-wireless g)# 7-122 Wireless Security Commands 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. • 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 wep Command Mode Interface Configuration (Wireless-VAP) Command Usage • WPA enables the bridge 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 bridge are not WPA enabled, the multicast-cipher 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. 7-123 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. 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 Enterprise AP(if-wireless g: VAP[0])#multicast-cipher TKIP Enterprise AP(if-wireless g)# mic_mode This command specifies how to calculate the Message Integrity Check (MIC). Syntax mic_mode • hardware - Uses hardware to calculate the MIC. • software - Uses software to calculate the MIC. Default Setting software Command 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 bridge for each transmitted packet and this can impact throughput and performance. The bridge supports a choice of hardware or software for MIC calculation. The performance of the bridge 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. • 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. 7-124 Wireless Security Commands 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) Pre-shared-key. Syntax wpa-pre-shared-key • 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 bridge’s VAP interface. Example Enterprise AP(if-wireless g: VAP[0])#wpa-pre-shared-key ASCII agoodsecret Enterprise AP(if-wireless g)# Related Commands auth (7-118) pmksa-lifetime This command sets the time for aging out cached WPA2 Pairwise Master Key Security Association (PMKSA) information for fast roaming. Syntax pmksa-lifetime minutes - The time for aging out PMKSA information. (Range: 0 - 14400 minutes) Default Setting 720 minutes 7-125 7 Command Line Interface Command 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 bridge 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 bridge 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 bridge, it requires full reauthentication. • The bridge can store up to 256 entries in the PMKSA cache. Example Enterprise AP(if-wireless g: VAP[0])#wpa-pre-shared-key ASCII agoodsecret Enterprise AP(if-wireless g: VAP[0])# pre-authentication This command enables WPA2 pre-authentication for fast secure roaming. Syntax pre-authentication • enable - Enables pre-authentication for the VAP interface. • disable - Disables pre-authentication for the VAP interface. Default Setting Disabled Command Mode Interface Configuration (Wireless-VAP) Command Usage • Each time a client roams to another bridge 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 bridge 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 bridge in the network, the bridge sends pre-authentication messages to the new bridge that include the client’s security association information. Then when the client sends an association request to the new bridge the client is known to be already authenticated, 7-126 Link Integrity Commands so it proceeds directly to key exchange and association. • To support pre-authentication, both clients and bridges in the network must be WPA2 enabled. • Pre-authentication requires all bridges in the network to be on the same IP subnet. Example Enterprise AP(if-wireless g: VAP[0])#wpa-pre-shared-key ASCII agoodsecret Enterprise AP(if-wireless g: VAP[0])# Link Integrity Commands The bridge provides a link integrity feature that can be used to ensure that wireless clients are connected to resources on the wired network. The bridge does this by periodically sending Ping messages to a host device in the wired Ethernet network. If the bridge detects that the connection to the host has failed, it disables the radio interfaces, forcing clients to find and associate with another bridge. When the connection to the host is restored, the bridge re-enables the radio interfaces. Table 7-20. Link Integrity Commands Command Function Mode Page link-integrity ping-detect Enables link integrity detection GC 7-128 link-integrity ping-host Specifies the IP address of a host device in the wired network GC 7-128 link-integrity ping-interval Specifies the time between each Ping sent to the link host GC 7-129 link-integrity ping-fail-retry Specifies the number of consecutive failed Ping counts before the link is determined as lost GC 7-129 link-integrity ethernet-detect Enables integrity check for Ethernet link GC 7-129 show link-integrity Displays the current link integrity configuration Exec 7-130 7-127 7 Command Line Interface link-integrity ping-detect This command enables link integrity detection. Use the no form to disable link integrity detection. Syntax [no] link-integrity ping-detect Default Setting Disabled Command Mode Global Configuration Command Usage • When link integrity is enabled, the IP address of a host device in the wired network must be specified. • The bridge periodically sends an ICMP echo request (Ping) packet to the link host IP address. When the number of failed responses (either the host does not respond or is unreachable) exceeds the limit set by the link-integrity ping-fail-retry command, the link is determined as lost. Example Enterprise AP(config)#link-integrity ping-detect Enterprise AP(config)# link-integrity ping-host This command configures the link host name or IP address.

In other words, the 802.11f protocol can ensure successful roaming between bridges in a multi-vendor environment. iapp This command enables the protocol signaling required to hand over wireless clients roaming between different 802.11f-compliant bridges. Use the no form to disable 802.11f signaling. Syntax [no] iapp Default Enabled Command Mode Global Configuration Command Usage The current 802.11 standard does not specify the signaling required between bridges in order to support clients roaming from one bridge to another. In particular, this can create a problem for clients roaming between bridges from different vendors. This command is used to enable or disable 802.11f handover signaling between different bridges, especially in a multi-vendor environment. Example Enterprise AP(config)#iapp Enterprise AP(config)# 7-131 7 Command Line Interface VLAN Commands The bridge 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 bridge, 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 bridge assigns the user to its own configured native VLAN ID. Caution: When VLANs are enabled, the bridge’s Ethernet port drops all received traffic that does not include a VLAN tag. To maintain network connectivity to the bridge and wireless clients, be sure that the bridge is connected to a device port on a wired network that supports IEEE 802.1Q VLAN tags. The VLAN commands supported by the bridge are listed below. Table 7-21. VLAN Commands Command Function Mode Page vlan Enables a single VLAN for all traffic GC 7-132 managementvlanid Configures the management VLAN for the bridge GC 7-133 vlan-id Configures the default VLAN for the VAP interface IC-W-VAP 7-133 vlan This command enables VLANs for all traffic. Use the no form to disable VLANs. Syntax [no] vlan enable Default Disabled Command Mode Global Configuration Command Description • When VLANs are enabled, the bridge tags frames received from wireless clients with the VLAN ID configured for each client on the RADIUS server. If the VLAN ID has not been configured for a client on the RADIUS server, then the frames are tagged with the bridge’s native VLAN ID. 7-132 VLAN Commands • Traffic entering the Ethernet port must be tagged with a VLAN ID that matches the bridge’s native VLAN ID, or with a VLAN tag that matches one of the wireless clients currently associated with the bridge. Example Enterprise AP(config)#vlan enable Reboot system now? : y Related Commands management-vlanid (7-133) management-vlanid This command configures the management VLAN ID for the bridge. Syntax management-vlanid vlan-id - Management VLAN ID. (Range: 1-4094) Default Setting Command Mode Global Configuration Command Usage The management VLAN is for managing the bridge. For example, the bridge allows traffic that is tagged with the specified VLAN to manage the bridge via remote management, SSH, SNMP, Telnet, etc. Example Enterprise AP(config)#management-vlanid 3 Enterprise AP(config)# Related Commands vlan (7-132) vlan-id This command configures the default VLAN ID for the VAP interface. Syntax vlan-id vlan-id - Native VLAN ID. (Range: 1-4094) 7-133 7 Command Line Interface Default Setting Command Mode Interface Configuration (Wireless-VAP) Command Usage • To implement the default VLAN ID setting for VAP interface, the bridge must enable VLAN support using the vlan command. • When VLANs are enabled, the bridge tags frames received from wireless clients with the default VLAN ID for the VAP interface. If IEEE 802.1X is being used to authenticate wireless clients, specific VLAN IDs can be configured on the RADIUS server to be assigned to each client. Using IEEE 802.1X and a central RADIUS server, up to 64 VLAN IDs can be mapped to specific wireless clients. • If the VLAN ID has not been configured for a client on the RADIUS server, then the frames are tagged with the default VLAN ID of the VAP interface. Example Enterprise AP(if-wireless g: VAP[0])#vlan-id 3 Enterprise AP(if-wireless g: VAP[0])# WMM Commands The bridge implements QoS using the Wi-Fi Multimedia (WMM) standard. Using WMM, the bridge 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 bridge to inter-operate with both WMM- enabled clients and other devices that may lack any WMM functionality. The WMM commands supported by the bridge are listed below. Table 7-22. WMM Commands Command Function Mode Page wmm Sets the WMM operational mode on the bridge IC-W 7-135 wmm-acknowledgepolicy Allows the acknowledgement wait time to be enabled or IC-W disabled for each Access Category (AC) 7-135 wmmparam Configures detailed WMM parameters that apply to the bridge (AP) or the wireless clients (BSS) 7-136 7-134 IC-W WMM Commands wmm This command sets the WMM operational mode on the bridge. Use the no form to disable WMM. Syntax [no] wmm • supported - WMM will be used for any associated device that supports this feature. Devices that do not support this feature may still associate with the bridge. • required - WMM must be supported on any device trying to associated with the bridge. Devices that do not support this feature will not be allowed to associate with the bridge. Default supported Command Mode Interface Configuration (Wireless) Example Enterprise AP(if-wireless a)#wmm required Enterprise AP(if-wireless a)# wmm-acknowledge-policy This command allows the acknowledgement wait time to be enabled or disabled for each Access Category (AC). Syntax wmm-acknowledge-policy • ac_number - Access categories. (Range: 0-3) • ack - Require the sender to wait for an acknowledgement from the receiver. • noack - Does not require the sender to wait for an acknowledgement from the receiver. Default ack Command Mode Interface 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 6-1). The direct mapping of the four ACs to 802.1D priorities is specifically intended to facilitate 7-135 7 Command Line Interface 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 bridges 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. Example Enterprise AP(if-wireless a)#wmm-acknowledge-policy 0 noack Enterprise AP(if-wireless a)# wmmparam This command configures detailed WMM parameters that apply to the bridge (AP) or the wireless clients (BSS). Syntax wmmparam • AP - Access Point • BSS - Wireless client • ac_number - 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 as shown in Table 6-1. (Range: 0-3) • LogCwMin - Minimum log value of the contention window. This is the initial upper limit of the random backoff wait time before wireless medium access can be attempted. The initial wait time is a random value between zero and the LogCwMin value. Specify the LogCwMin value. Note that the LogCwMin value must be equal or less than the LogCwMax value. (Range: 1-15 microseconds) • LogCwMax - Maximum log value of the contention window. This is the maximum upper limit of the random backoff wait time before wireless medium access can be attempted. The contention window is doubled after each detected collision up to the LogCwMax value. Note that the CWMax value must be greater or equal to the LogCwMin value. (Range: 1-15 microseconds) • AIFS - Arbitrary InterFrame Space specifies the minimum amount of wait time before the next data transmission attempt. (Range: 1-15 microseconds) • TXOPLimit - Transmission Opportunity Limit specifies the maximum time an AC transmit queue has access to the wireless medium. When an AC queue is granted a transmit opportunity, it can transmit data for a time up to the TxOpLimit. This data bursting greatly improves the efficiency for high data-rate traffic. (Range: 0-65535 microseconds) 7-136 WMM Commands • admission_control - The admission control mode for the access category. When enabled, clients are blocked from using the access category. (Options: 0 to disable, 1 to enable) Default AP Parameters WMM Parameters AC0 (Best Effort) AC1 (Background) AC2 (Video) AC3 (Voice) LogCwMin LogCwMax 10 10 AIFS TXOP Limit 94 47 Admission Control Disabled Disabled Disabled Disabled WMM Parameters AC0 (Best Effort) AC1 (Background) AC2 (Video) AC3 (Voice) LogCwMin LogCwMax 10 AIFS TXOP Limit 94 47 Admission Control Disabled Disabled Disabled Disabled BSS Parameters Command Mode Interface Configuration (Wireless) Example Enterprise AP(if-wireless a)#wmmparams ap 0 4 6 3 1 1 Enterprise AP(if-wireless a)# 7-137 7 Command Line Interface 7-138 A TROUBLESHOOTING Check the following items before you contact local Technical Support. 1 If wireless bridge units do not associate with each other, check the following: Check the power injector LED for each bridge unit to be sure that power is being supplied Be sure that antennas in the link are properly aligned. Be sure that channel settings match on all bridges If encryption is enabled, ensure that all bridge links are configured with the same encryption keys. 2 If you experience poor performance (high packet loss rate) over the wireless bridge link: Check that the range of the link is within the limits for the antennas used. Be sure that antennas in the link are properly aligned. Check that there is an unobstructed radio line-of-sight between the antennas. Be sure there is no interference from other radio sources. Try setting the bridge link to another radio channel. Be sure there is no other radio transmitter too close to either antenna. If necessary, move the antennas to another location. 3 If wireless clients cannot access the network, check the following: Be sure the bridge 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. If authentication is being performed through a RADIUS server, ensure that the clients are properly configured on the RADIUS server. If authentication is being performed through IEEE 802.1X, be sure the wireless users have installed and properly configured 802.1X client software. If MAC address filtering is enabled, be sure the client’s address is included in the local filtering database or on the RADIUS server database. If the wireless clients are roaming between bridges, make sure that all the bridges and wireless devices in the Extended Service Set (ESS) are configured to the same SSID, and authentication method. 4 If the bridge cannot be configured using the Telnet, a web browser, or SNMP software: Be sure to have configured the bridge with a valid IP address, subnet mask and default gateway. If VLANs are enabled on the bridge, the management station should be configured to send tagged frames with a VLAN ID that matches the bridge’s management VLAN (default VLAN 1, page 18). However, to manage the bridge from a wireless client, the AP Management Filter should be disabled (page 18). Check that you have a valid network connection to the bridge and that the Ethernet port or the wireless interface that you are using has not been disabled. If you are connecting to the bridge through the wired Ethernet interface, check the network cabling between the management station and the bridge. If you are connecting to bridge from a wireless client, ensure that you have a valid connection to the bridge. If you cannot connect using Telnet, you may have exceeded the maximum number of concurrent Telnet sessions permitted (i.e, four sessions). Try connecting again at a later time. 5 If you cannot access the on-board configuration program via a serial port connection: A-1 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. 6 If you forgot or lost the password: Set the bridge to its default configuration by pressing the reset button on the back panel for 5 seconds or more. Then use the default user name “admin” and a null password to access the management interface. 7 If all other recovery measure fail, and the bridge is still not functioning properly, take any of these steps: Reset the bridge’s hardware using the console interface, web interface, or through a power reset. Reset the bridge to its default configuration by pressing the reset button on the back panel for 5 seconds or more. Then use the default user name “admin” and a null password to access the management interface.

A-13 A-14 C 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. CAUTION: DO NOT plug a phone jack connector into a power injector RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards. The following figure illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins. C-1 10/100BASE-TX PIN ASSIGNMENTS Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet). The RJ-45 Input port on the power injector is wired with MDI pinouts. This means that you must use crossover cables for connections to PCs or servers, and straight-through cable for connections to switches or hubs. However, when connecting to devices that support automatic MDI/MDI-X pinout configuration, you can use either straight-through or crossover cable. 10/100BASE-TX MDI and MDI-X Port Pinouts Pin MDI-X Signal Name MDI Signal Name Receive Data plus (RD+) Transmit Data plus (TD+) Receive Data minus (RD-) Transmit Data minus (TD-) Transmit Data plus (TD+) Receive Data plus (RD+) Transmit Data minus (TD-) Receive Data minus (RD-) 4,5,7,8 Not used Not used Note: The “+” and “-” signs represent the polarity of the wires that make up each wire pair. C-2 STRAIGHT-THROUGH WIRING Because the 10/100 Mbps Input port on the power injector uses an MDI pin configuration, you must use “straight-through” cable for network connections to hubs or switches that only have MDI-X ports. However, if the device to which you are connecting supports automatic MDI/MDI-X operation, you can use either “straight-through” or “crossover” cable. EIA/TIA 568B RJ-45 Wiring Standard 10/100BASE-TX Straight-through Cable White/Orange Stripe Orange End A White/Green Stripe Blue White/Blue Stripe Green White/Brown Stripe Brown C-3 End B CROSSOVER WIRING Because the 10/100 Mbps port on the power injector uses an MDI pin configuration, you must use “crossover” cable for network connections to PCs, servers or other end nodes that only have MDI ports. However, if the device to which you are connecting supports automatic MDI/MDI-X operation, you can use either “straight-through” or “crossover” cable. EIA/TIA 568B RJ-45 Wiring Standard 10/100BASE-TX Crossover Cable White/Orange Stripe Orange End A White/Green Stripe Blue White/Blue Stripe Green White/Brown Stripe Brown C-4 End B 8-PIN DIN CONNECTOR PINOUT The Ethernet cable from the power injector connects to an 8-pin DIN connector on the wireless bridge. This connector is described in the following figure and table. 8-Pin DIN Ethernet Port Pinout Pin Signal Name Transmit Data plus (TD+) Transmit Data minus (TD-) Receive Data plus (RD+) +48 VDC power +48 VDC power Receive Data minus (RD-) Return power Return power Note: The “+” and “-” signs represent the polarity of the wires that make up each wire pair. C-5 8-PIN DIN TO RJ-45 CABLE WIRING To construct an extended Ethernet cable to connect from the power injector’s RJ-45 Output port to the wireless bridge’s 8-pin DIN connector, follow the wiring diagram below.

D-7 D-8 GLOSSARY 10BASE-T IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3 or better UTP cable. 100BASE-TX IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5 or better UTP cable. Access Point An internetworking device that seamlessly connects wired and wireless networks. Access points attached to a wired network, support the creation of multiple radio cells that enable roaming throughout a facility. Ad Hoc A group of computers connected as an independent wireless network, without an access point. Advanced Encryption Standard (AES) An encryption algorithm that implements symmetric key cryptography. AES provides very strong encryption using a completely different ciphering algorithm to TKIP and WEP. Authentication The process to verify the identity of a client requesting network access. IEEE 802.11 specifies two forms of authentication: open system and shared key. Backbone The core infrastructure of a network. The portion of the network that transports information from one central location to another central location where it is unloaded onto a local system. Basic Service Set (BSS) A set of 802.11-compliant stations and an access point that operate as a fully-connected wireless network. Beacon A signal periodically transmitted from the access point that is used to identify the service set, and to maintain contact with wireless clients. Glossary-1 Broadcast Key Broadcast keys are sent to stations using 802.1X dynamic keying. Dynamic broadcast key rotation is often used to allow the access point to generate a random group key and periodically update all key-management capable wireless clients. CSMA/CA Carrier Sense Multiple Access with Collision Avoidance. Dynamic Host Configuration Protocol (DHCP) Provides a framework for passing configuration information to hosts on a TCP/IP network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability of automatic allocation of reusable network addresses and additional configuration options. Encryption Data passing between the access point and clients can use encryption to protect from interception and evesdropping. Extended Service Set (ESS) More than one wireless cell can be configured with the same Service Set Identifier to allow mobile users can roam between different cells with the Extended Service Set. Extensible Authentication Protocol (EAP) An authentication protocol used to authenticate network clients. EAP is combined with IEEE 802.1X port authentication and a RADIUS authentication server to provide “mutual authentication” between a client, the access point, and the a RADIUS server Ethernet A popular local area data communications network, which accepts transmission from computers and terminals. File Transfer Protocol (FTP) A TCP/IP protocol used for file transfer. Hypertext Transfer Protocol (HTTP) HTTP is a standard used to transmit and receive all data over the World Wide Web. IEEE 802.11a A wireless standard that supports high-speed communications in the 5 GHz band using Orthogonal Frequency Division Multiplexing (OFDM). The standard supports data rates of 6, 12, 24, and 54 Mbps. Glossary-2 IEEE 802.11b A wireless standard that supports wireless communications in the 2.4 GHz band using Direct Sequence Spread Spectrum (DSSS). The standard provides for data rates of 1, 2, 5.5, and 11 Mbps. IEEE 802.11g A wireless standard that supports wireless communications in the 2.4 GHz band using using Orthogonal Frequency Division Multiplexing (OFDM). The standard provides for data rates of 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps. IEEE 802.11g is also backward compatible with IEEE 802.11b. IEEE 802.1X Port Authentication controls access to the switch ports by requiring users to first enter a user ID and password for authentication. Infrastructure An integrated wireless and wired LAN is called an infrastructure configuration. Inter Access Point Protocol (IAPP) A protocol that specifies the wireless signaling required to ensure the successful handover of wireless clients roaming between different 802.11f-compliant access points. Local Area Network (LAN) A group of interconnected computer and support devices. MAC Address The physical layer address used to uniquely identify network nodes. Network Time Protocol (NTP) NTP provides the mechanisms to synchronize time across the network. The time servers operate in a hierarchical-master-slave configuration in order to synchronize local clocks within the subnet and to national time standards via wire or radio. Open System A security option which broadcasts a beacon signal including the access point’s configured SSID. Wireless clients can read the SSID from the beacon, and automatically reset their SSID to allow immediate connection to the nearest access point. Orthogonal Frequency Division Multiplexing (ODFM) OFDM/ allows multiple users to transmit in an allocated band by dividing the bandwidth into many narrow bandwidth carriers. Power over Ethernet (PoE) A specification for providing both power and data to low-power network devices using a single Category 5 Ethernet cable. PoE provides greater flexibility in the locating of access point’s and network devices, and significantly decreased installation costs. Glossary-3 RADIUS A logon authentication protocol that uses software running on a central server to control access to the network. Roaming A wireless LAN mobile user moves around an ESS and maintains a continuous connection to the infrastructure network. RTS Threshold Transmitters contending for the medium may not be aware of each other. RTS/CTS mechanism can solve this “Hidden Node Problem.” If the packet size is smaller than the preset RTS Threshold size, the RTS/CTS mechanism will NOT be enabled. Service Set Identifier (SSID) An identifier that is attached to packets sent over the wireless LAN and functions as a password for joining a particular radio cell; i.e., Basic Service Set (BSS). Session Key Session keys are unique to each client, and are used to authenticate a client connection, and correlate traffic passing between a specific client and the access point. Shared Key A shared key can be used to authenticate each client attached to a wireless network. Shared Key authentication must be used along with the 802.11 Wireless Equivalent Privacy algorithm. Simple Network Management Protocol (SNMP) The application protocol in the Internet suite of protocols which offers network management services. Simple Network Time Protocol (SNTP) SNTP allows a device to set its internal clock based on periodic updates from a Network Time Protocol (NTP) server. Updates can be requested from a specific NTP server, or can be received via broadcasts sent by NTP servers. Temporal Key Integrity Protocol (TKIP) A data encryption method designed as a replacement for WEP. TKIP avoids the problems of WEP static keys by dynamically changing data encryption keys. Trivial File Transfer Protocol (TFTP) A TCP/IP protocol commonly used for software downloads. Virtual Access Point (VAP) Virtual AP technology multiplies the number of Access Points present within the RF footprint of a single physical access device. With Virtual AP technology, WLAN users within the device’s footprint can associate with what appears to be different access points and their associated Glossary-4 network services. All the services are delivered using a single radio channel, enabling Virtual AP technology to optimize the use of limited WLAN radio spectrum. Virtual LAN (VLAN) A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. A VLAN serves as a logical workgroup with no physical barriers, and allows users to share information and resources as though located on the same LAN. Wi-Fi Protected Access WPA employs 802.1X as its basic framework for user authentication and dynamic key management to provide an enhanced security solution for 802.11 wireless networks. Wired Equivalent Privacy (WEP) WEP is based on the use of security keys and the popular RC4 encryption algorithm. Wireless devices without a valid WEP key will be excluded from network traffic. WPA Pre-shared Key (PSK) PSK can be used for small office networks that may not have the resources to configure and maintain a RADIUS server, WPA provides a simple operating mode that uses just a pre-shared password for network access.
