–  17  –Section IGetting StartedThis section provides an overview of the access point, and introduces some basic concepts about wireless networking. It also describes the basic settings required to access the management interface.This section includes these chapters:◆“Introduction” on page 18◆“Initial Configuration” on page 24
–  18  –1IntroductionThe access point (AP) runs software that includes a network management agent. The agent offers a variety of management options, including SNMP and a web-based interface. A PC may also be connected directly to the AP’s console port for configuration using a command line interface (CLI).Configuration OptionsThe AP’s HTTP web agent allows you to configure AP parameters, monitor wireless connections, and display statistics using a standard web browser such as Internet Explorer 6.x or above, and Mozilla Firefox 3.6.2/4/5. The AP’s web management interface can be accessed from any computer attached to the network.The CLI program can be accessed by a direct connection to the RS-232 serial console port on the AP, or remotely by a Telnet or Secure Shell (SSH) connection over the network.The AP’s management agent also supports SNMP (Simple Network Management Protocol). This SNMP agent permits the AP to be managed from any computer in the network using network management software.The AP’s web interface, console interface, and SNMP agent allow you to perform management functions such as:◆Set management access user names and passwords◆Configure IP settings◆Configure SNMP parameters ◆Configure 2.4 GHz and 5 GHz radio settings◆Control access through wireless security settings◆Filter packets using Access Control Lists (ACLs)◆Upload and download system firmware or configuration files◆Display system information and statistics
Chapter 1  |  IntroductionConsole Port Connection–  19  –Console Port ConnectionThe AP provides an RS-232 serial console port that enables a connection to a PC or terminal for monitoring and configuring the AP. A null-modem console cable is provided with the AP. Attach a VT100-compatible terminal, or a PC running a terminal emulation program to the AP. You can use the console cable provided with this package, or use a null-modem cable that complies with the wiring assignments shown in the Installation Guide.To connect a terminal to the console port, complete the following steps: 1. Connect the console cable to the serial port on a terminal, or a PC running terminal emulation software, and tighten the captive retaining screws on the DB-9 connector.2. Connect the other end of the cable to the console port on the AP.3. Make sure the terminal emulation software is set as follows:■Select the appropriate serial port (COM port 1 or COM port 2). ■Set the baud rate to 115200 bps.■Set the data format to 8 data bits, 1 stop bit, and no parity. ■Set flow control to none. ■Set the emulation mode to VT100. ■When using HyperTerminal, select Terminal keys, not Windows keys. Note: Once you have set up the terminal correctly, the console login screen will be displayed. For a description of how to use the CLI, see “Using the Command Line Interface” on page 109. For a list of all the CLI commands, refer to “Index of CLI Commands” on page 274.Console Login Access to the CLI is controlled by user names and passwords. The AP has a default user name and password. To log into the CLI using the default user name and password, perform these steps:1. To initiate your console connection, press <Enter>. The “User Access Verification” procedure starts.
Chapter 1  |  IntroductionNetwork Connections–  20  –2. At the login prompt, enter “admin.”3. At the Password prompt, press <Enter>. There is no default password. 4. The session is opened and the CLI displays the “Accton#” prompt indicating you have access to the CLI commands. Example(none) login: adminPassword:Jan  1 11:33:13 login[1918]: root login on 'ttyS0'SMC#Network ConnectionsPrior to accessing the AP’s management agent through a network connection, you must first configure it with a valid IP address, subnet mask, and default gateway using a console connection, or the DHCP protocol.The AP has a static default management IPv4 address of 192.168.1.10 and a subnet mask of 255.255.255.0. Once the AP’s IP settings are configured for the network, you can access the AP’s management agent from anywhere within the attached network. The management agent can be accessed using Telnet from any computer attached to the network. The AP can also be managed by any computer using a web browser, or from a network computer using SNMP network management software.Connecting to the Web InterfaceThe AP offers a user-friendly web-based management interface for the configuration of all the unit’s features. Any PC directly attached to the unit can access the management interface using a web browser, such as Internet Explorer (version 6.x or above) or Firefox (version 2.x or above).You may want to make initial configuration changes by connecting a PC directly to the AP’s LAN port. The AP has a default management IP address of 192.168.1.10 and a subnet mask of 255.255.255.0. You must set your PC IP address to be on the same subnet as the AP (that is, the PC and AP addresses must both start 192.168.1.x).To access the AP’s web management interface, follow these steps:1. Use your web browser to connect to the management interface using the default IP address of 192.168.1.10.
Chapter 1  |  IntroductionConnecting to the Web Interface–  21  –2. Log into the interface by entering the default username “admin” with no password, then click Login.Note: It is strongly recommended to change the default user name and password the first time you access the web interface. For information on changing user names and passwords, See “Administration Settings” on page 34.Figure 1:  Login PageHome Page and MainMenuAfter logging in to the web interface, the home page displays. The home page shows some basic settings for the AP, including Country Code and the management access password.Figure 2:  The Home Page

–  24  –2Initial ConfigurationThe AP’s initial configuration steps can be made through the CLI or web browser interface. If the AP is not configured with an IP address that is compatible with your network. You can first use the command line interface (CLI) as described below to configure a valid IP address. CLI Initial Configuration StepsFirst connect to the AP’s console port and log in to the CLI, as described in “Console Port Connection” on page 19. Then proceed with the required configuration.Setting an IP Address If the default IP address is not compatible with your network or a DHCP server is not available, the AP’s IP address must be configured manually using the CLI. Type “configure” to enter configuration mode, then type “interface ethernet” to access the Ethernet interface-configuration mode.SMC#configureSMC(config)#interface ethernetSMC(config-if)#First type “no ip dhcp” to disable DHCP client mode. Then type “ip address ip-address netmask gateway,” where “ip-address” is the access point’s IP address, “netmask” is the network mask for the network, and “gateway” is the default gateway router. Check with your system administrator to obtain an IP address that is compatible with your network.SMC(if-ethernet)#no ip dhcpSMC(if-ethernet)#ip address 192.168.2.2 255.255.255.0 192.168.2.254SMC(if-ethernet)#After configuring the access point’s IP parameters, you can access the management interface from anywhere within the attached network. The command line interface can also be accessed using Telnet from any computer attached to the network. Note: Command examples shown later in this manual abbreviate the console prompt to “AP” for simplicity.
Chapter 2  |  Initial ConfigurationCLI Initial Configuration Steps–  25  –Setting a Password If you are logging in to the CLI for the fist time, you should define management access passwords for an administrator and guest (used for CLI and web management), record them, and then keep them in a safe place.Note: If you loose your management access passwords, you will need to use the Reset button on the AP to set the configuration back to factory default values.Passwords can consist of 5 to 32 alphanumeric characters and are case sensitive. To prevent unauthorized access to the AP, set the passwords as follows:Open the console interface to access the CLI prompt. Type “configure” and press <Enter>. Type “password admin null password,” w here “null” is the default old password, and “password” is your new password. Press <Enter>. ExampleAP#configureAP(config)#password admin null tpschrisAP(config)#Setting the CountryCodeYou must set the country code of the AP to be sure that the radios operate according to permitted local regulations. That is, setting the country code restricts operation of the AP to the radio channels and transmit power levels permitted for wireless networks in the specified country. Caution: You must set the country code to the country of operation. Setting the country code ensures that the radios operate within the local regulations specified for wireless networks. Note: The country code selection is for non-US models only and is not available to all US models. Per FCC regulation, all Wi-Fi products marketed in the US must be fixed to US operation channels only.From the CLI prompt, type “country ?” to display the list of country codes. Select the code for your country, and enter the command again, following by your country code (for example., “tw” for Taiwan).ExampleAP#country ?  WORD Country code:       AL-ALBANIA, DZ-ALGERIA, AR-ARGENTINA, AM-ARMENIA, AU-AUSTRALIA,       AT-AUSTRIA, AZ-AZERBAIJAN,       BH-BAHRAIN, BY-BELARUS, BE-BELGIUM, BZ-BELIZE, BO-BOLIVIA,

(Default: SMC2890W-AN or SMC2891W-AN)Change Password◆Username/Guest Username — The name of the user is fixed as either “admin” or “guest” and is not configurable.◆Old Password — If the unit has been configured with a password already, enter that password, otherwise enter the default password “null.”◆New Password — The password for management access. (Length: 5-32 characters, case sensitive) ◆Confirm New Password — Enter the password again for verification.Country Code◆Country Code — Configures the access point’s country code from a drop down menu, which identifies the country of operation and sets the authorized radio channels.
Chapter 2  |  Initial ConfigurationWeb Quick Start–  28  –Caution: You must set the country code to the country of operation. Setting the country code restricts operation of the access point to the radio channels and transmit power levels permitted for wireless networks in the specified country.◆Cancel — Cancels the newly entered settings and restores the orignals.◆Next — Proceeds to the next page.Step 2 The Step 2 page of the Quick Start configures IP settings and DHCP client status.Figure 6:  Quick Start - Step 2The following items are displayed on this page:DHCP◆DHCP Status — Enables/disables DHCP on the access point. (Default: Disabled)◆IP Address — Specifies an IP address for the access point. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. (Default: 192.168.2.10.)◆Subnet Mask — Indicates the local subnet mask. Select the desired mask from the drop down menu. (Default: 255.255.255.0)◆Default Gateway — The default gateway is the IP address of the router for the access point, which is used if the requested destination address is not on the local subnet. (Default: 192.168.2.254)If you have DNS, RADIUS, or other network servers located on another subnet, type the IP address of the default gateway router in the text field provided.
Chapter 2  |  Initial ConfigurationWeb Quick Start–  29  –◆Primary and Secondary DNS Address — The IP address of Domain Name Servers on the network. A DNS maps numerical IP addresses to domain names and can be used to identify network hosts by familiar names instead of the IP addresses. (The default Primary and Secondary DNS addresses are null values.)◆Management IP — The IPv4 address of the AP through which you can access management interfaces. ■Management IP Address — Specifies an IPv4 address for management of the access point. (Default: 192.168.1.10.)■Management Subnet Mask — Indicates the local subnet mask. (Default: 255.255.255.0)◆Prev — Returns to the previous screen.◆Cancel — Cancels the newly entered settings and restores the orignals.◆Next — Proceeds to the final step in the Quick Start wizard.Step 3 The Step 3 page of the Quick Start configures basic radio and wireless security settings.Figure 7:  Quick Start - Step 3The following items are displayed on this page:Basic Setting◆SSID — The name of the basic service set provided by the primary VAP interface. Clients that want to connect to the network through the AP must set their SSID to the same as that of a VAP interface. (Default: EAP9112A_11BGN_0; Range: 1-32 characters)
Chapter 2  |  Initial ConfigurationWeb Quick Start–  30  –Security◆Association Mode — Defines the mode with which the VAP will associate with clients. (For more information on security modes, see “Wireless Security Settings” on page 78.)■Open System: The VAP is configured by default as an “open system,” which broadcasts a beacon signal including the configured SSID. Wireless clients with an SSID setting of “any” can read the SSID from the beacon and automatically set their SSID to allow immediate connection. ■WPA: WPA employs a combination of several technologies to provide an enhanced security solution for 802.11 wireless networks.■WPA-PSK: For enterprise deployment, WPA requires a RADIUS authentication server to be configured on the wired network. However, 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. The Pre-Shared Key mode uses a common password for user authentication that is manually entered on the access point and all wireless clients. The PSK mode uses the same TKIP packet encryption and key management as WPA in the enterprise, providing a robust and manageable alternative for small networks.■WPA2: WPA was introduced as an interim solution for the vulnerability of WEP pending the ratification of the IEEE 802.11i wireless security standard. In effect, the WPA security features are a subset of the 802.11i standard. WPA2 includes the now ratified 802.11i standard, but also offers backward compatibility with WPA. Therefore, WPA2 includes the same 802.1X and PSK modes of operation and support for TKIP encryption. ■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.◆Encryption Method — Selects an encryption method for the global key used for multicast and broadcast traffic, which is supported by all wireless clients.■WEP: WEP is used as the multicast encryption cipher. You should select WEP only when both WPA and WEP clients are supported. ■TKIP: TKIP is used as the multicast encryption cipher.■AES-CCMP: AES-CCMP is used as the multicast encryption cipher. AES-CCMP is the standard encryption cipher required for WPA2.
Chapter 2  |  Initial ConfigurationWeb Quick Start–  31  –Authentication◆802.1X — The access point supports 802.1X authentication only for clients initiating the 802.1X authentication process (i.e., the access point does not initiate 802.1X authentication). For clients initiating 802.1X, only those successfully authenticated are allowed to access the network. For those clients not initiating 802.1X, access to the network is allowed after successful wireless association with the access point. The 802.1X mode allows access for clients not using WPA or WPA2 security.◆Pre-Authentication — When using WPA2 over 802.1X, pre-authentication can be enabled, which allows clients to roam to a new access point and be quickly associated without performing full 802.1X authentication. (Default: Disabled)◆802.1x Reauthentication Time — The time period after which a connected client must be re-authenticated. During the re-authentication process of verifying the client’s credentials on the RADIUS server, the client remains connected the network. Only if re-authentication fails is network access blocked. (Range: 0-65535 seconds; Default: 0 means disabled)Note: When 802.1X is enabled, be sure to configure RADIUS server details. For more information, see “RADIUS Settings” on page 37. Step 4 When you have clicked “Set” after Step 3, the AP saves the Quick Start configuration settings. Click “OK” to confirm that the Quick Start is complete.Figure 8:  Quick Start - Step 4

(Default: SMC2890W-AN or SMC2891W-AN; Range: 1-32 characters)◆Username/Guest Username — The name of the user is fixed as either “admin” or “guest” and is not configurable.◆Old Password — Type your current password.◆New Password — The password for management access. (Length: 5-32 characters, case sensitive) ◆Confirm New Password — Enter the password again for verification.◆Country Code — Configures the AP’s country code, which identifies the country of operation and sets the authorized radio channels.
Chapter 3  |  System SettingsIPv4 Address–  35  –Caution: You must set the country code to the country of operation. Setting the country code restricts operation of the AP to the radio channels and transmit power levels permitted for wireless networks in the specified country.IPv4 AddressConfiguring the AP with an IPv4 address expands your ability to manage the AP. A number of the AP’s features depend on IPv4 addressing to operate.You can use the web browser interface to access IPv4 addressing only if the access point already has an IPv4 address that is reachable through your network. By default, the AP will be not be automatically configured with IPv4 settings from a Dynamic Host Configuration Protocol (DHCP) server. The default IPv4 address for management access is 192.168.1.10, with a subnet mask 255.255.255.0. Figure 10:  IPv4 ConfigurationThe following items are displayed on this page:◆DHCP Status — Enables/disables DHCP on the access point.◆IP Address — Specifies an IP address for the access point. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. (Default: 192.168.2.10.)◆Subnet Mask — Indicates the local subnet mask. (Default: 255.255.255.0)◆Default Gateway — The default gateway is the IP address of the router for the access point, which is used if the requested destination address is not on the local subnet.
Chapter 3  |  System SettingsIPv6 Address–  36  –If you have management stations, DNS, RADIUS, or other network servers located on another subnet, type the IP address of the default gateway router in the text field provided. ◆Primary and Secondary DNS Address — The IP address of Domain Name Servers on the network.

If you have one or more DNS servers located on the local network, type the IPv6 addresses in the text fields provided.RADIUS SettingsRemote Authentication Dial-in User Service (RADIUS) is an authentication protocol that uses software running on a central server to control access to RADIUS-aware devices on the network. An authentication server contains a database of user credentials for each user that requires access to the network.Primary andSecondary RADIUSServer SetupA primary RADIUS server must be specified for the access point to implement IEEE 802.1X network access control and Wi-Fi Protected Access (WPA) wireless security. A secondary RADIUS server may also be specified as a backup should the primary server fail or become inaccessible.In addition, you can configure a RADIUS Accounting server to receive user-session accounting information from the access point. RADIUS Accounting can be used to provide valuable information on user activity in the network.This guide assumes that you have already configured RADIUS server(s) to support the access point. Configuration of RADIUS server software is beyond the scope of this guide, refer to the documentation provided with the RADIUS server software.
Chapter 3  |  System SettingsRADIUS Settings–  38  –Figure 12:  RADIUS SettingsThe following items are displayed on the RADIUS Settings page:◆RADIUS Status — Enables/disables the primary RADIUS server.◆IP Address — Specifies the IP address or host name of the RADIUS server.◆Port (1024-65535) — The UDP port number used by the RADIUS server for authentication messages. (Range: 1024-65535; Default: 1812)◆Key — A shared text string used to encrypt messages between the access point and the RADIUS server. Be sure that the same text string is specified on the RADIUS server. Do not use blank spaces in the string. (Maximum length: 255 characters)RADIUS Accounting The following items are displayed on the RADIUS Settings page:◆Account Status — Enables/disables RADIUS accounting.◆IP Address — Specifies the IP address or host name of the RADIUS accounting server.
Chapter 3  |  System SettingsSystem Time–  39  –◆Port (1024-65535) — The UDP port number used by the RADIUS accounting server for authentication messages. (Range: 1024-65535; Default: 1813)◆Key — A shared text string used to encrypt messages between the access point and the RADIUS accounting server. Be sure that the same text string is specified on the RADIUS server. Do not use blank spaces in the string. (Maximum length: 255 characters)◆Interim Update Timeout (60-86400) — The interval between transmitting accounting updates to the RADIUS server. (Range: 60-86400; Default: 300 seconds)System TimeSimple Network Time Protocol (SNTP) allows the access point to set its internal clock based on periodic updates from a time server (SNTP or NTP). Maintaining an accurate time on the access point enables the system log to record meaningful dates and times for event entries. If the clock is not set, the access point will only record the time from the factory default set at the last bootup.The access point acts as an SNTP client, periodically sending time synchronization requests to specific time servers. You can configure up to two time server IP addresses. The access point will attempt to poll each server in the configured sequence.Figure 13:  SNTP Settings
Chapter 3  |  System SettingsVLAN Configuration–  40  –SNTP Server Settings Configures the access point to operate as an SNTP client. When enabled, at least one time server IP address must be specified.◆SNTP Status — Enables/disables SNTP. (Default: enabled)◆Primary Server — The IP address of an SNTP or NTP time server that the access point attempts to poll for a time update. ◆Secondary Server — The IP address of a secondary SNTP or NTP time server. The access point first attempts to update the time from the primary server; if this fails it attempts an update from the secondary server.Time Zone Setting SNTP uses Greenwich Mean Time, or GMT (sometimes referred to as Coordinated Universal Time, or UTC) based on the time at the Earth’s prime meridian, zero degrees longitude. To display a time corresponding to your local time, you must indicate the number of hours your time zone is located before (east) or after (west) GMT.◆Time Zone — Select from the scroll down list the locale you are situated most close to, for example for New York, select ‘(GMT-05) Eastern Time (US & Canada)’.Daylight SavingSettingsThe access point provides a way to automatically adjust the system clock for Daylight Savings Time changes. To use this feature you must define the month and date to begin and to end the change from standard time. During this period the system clock is set back by one hour.◆Daylight Saving Status — Enalbes/disables daylight savings time. (Default: disabled)When enabled, set the month, day, and week to start and stop the daylight savings time.VLAN ConfigurationVLANs (virtual local area networks) are turned off by default when first installing the access point. If turned on they will automatically tag any packets received by the LAN port before sending them on to the relevant VAP (virtual access point).The access point can employ VLAN tagging support to control access to network resources and increase security. VLANs separate traffic passing between the access point, associated clients, and the wired network. There can be a default VLAN for each VAP (Virtual Access Point) interface, and a management VLAN for the access point.
Chapter 3  |  System SettingsVLAN Configuration–  41  –Note the following points about the access point’s VLAN support:◆The management VLAN is for managing the access point through remote management tools, such as the web interface, SSH, SNMP, or Telnet. The access point only accepts management traffic that is tagged with the specified management VLAN ID.◆All wireless clients associated to the access point are assigned to a VLAN. Wireless clients are assigned to the default VLAN for the VAP interface with which they are associated. The access point only allows traffic tagged with default VLAN IDs to access clients associated on each VAP interface.◆When VLAN support is enabled on the access point, traffic passed to the wired network is tagged with the appropriate VLAN ID, either a VAP default VLAN ID, or the management VLAN ID. Traffic received from the wired network must also be tagged with one of these known VLAN IDs. Received traffic that has an unknown VLAN ID or no VLAN tag is dropped.◆When VLAN support is disabled, the access point does not tag traffic passed to the wired network and ignores the VLAN tags on any received frames.Note: Before enabling VLAN tagging on the access point, be sure to configure the attached network switch port to support tagged VLAN frames from the access point’s management VLAN ID and default VLAN IDs. Otherwise, connectivity to the access point will be lost when you enable the VLAN feature.Figure 14:  Setting the VLAN IdentityThe following items are displayed on this page:◆VLAN Classification — Enables VLAN packet tagging. (Default: disabled)◆Management VLAN ID — The VLAN ID that traffic must have to be able to manage the access point. (Range 1-4094; Default: 4093)◆Native VLAN ID —  The VLAN ID assigned to untagged packets received by the LAN port. (Range: 1-4094; Default: 1)
Chapter 3  |  System SettingsSystem Logs–  42  –System LogsThe access point can be configured to send event and error messages to a System Log Server. The system clock can also be synchronized with a time server, so that all the messages sent to the Syslog server are stamped with the correct time and date.Figure 15:  System Log SettingsThe following items are displayed on this page:◆Syslog Status — Enables/disables the logging of error messages. (Default: enabled)◆Server 1~4 — Enables the sending of log messages to a Syslog server host. Up to four Syslog servers are supported on the access point.

Chapter 3  |  System SettingsBridge STP Configuration–  45  –◆Memory Status — Displays detailed information on the current memory utilization.Bridge STP ConfigurationThe Bridge menu enables configuration of the Spanning Tree Protocol (STP) and the address table aging time.Spanning TreeProtocol (STP)The Spanning Tree Protocol (STP) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the wireless bridge to interact with other bridging devices (that is, an STP-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.STP uses a distributed algorithm to select a bridging device (STP-compliant switch, bridge or router) that serves as the root of the spanning tree network. It selects a root port on each bridging device (except for the root device) which incurs the lowest path cost when forwarding a packet from that device to the root device. Then it selects a designated bridging device from each LAN which incurs the lowest path cost when forwarding a packet from that LAN to the root device. All ports connected to designated bridging devices are assigned as designated ports. After determining the lowest cost spanning tree, it enables all root ports and designated ports, and disables all other ports. Network packets are therefore only forwarded between root ports and designated ports, eliminating any possible network loops.Once a stable network topology has been established, all bridges listen for Hello BPDUs (Bridge Protocol Data Units) transmitted from the root bridge. If a bridge does not get a Hello BPDU after a predefined interval (Maximum Age), the bridge assumes that the link to the root bridge is down. This bridge will then initiate negotiations with other bridges to reconfigure the network to reestablish a valid network topology.
Chapter 3  |  System SettingsBridge STP Configuration–  46  –Figure 17:  Spanning Tree ProtocolBridgeSets STP bridge link parameters.The following items are displayed on the STP page:◆Spanning Tree Protcol — Enables/disables STP on the AP. (Default: Disabled)◆Priority — Used in selecting the root device, root port, and designated port. The device with the highest priority becomes the STP root device. However, if all devices have the same priority, the device with the lowest MAC address will then become the root device. (Note that lower numeric values indicate higher priority.)  (Default:32768; Range: 0-65535)◆Max Age — The maximum time (in seconds) a device can wait without receiving a configuration message before attempting to reconfigure. All device ports (except for designated ports) should receive configuration messages at regular intervals. Any port that ages out STP information (provided in the last configuration message) becomes the designated port for the attached LAN. If it is a root port, a new root port is selected from among the device ports attached

(Default: 2 seconds; Range: 1-10 seconds)Minimum: 1Maximum: The lower of 10 or [(Max. Message Age / 2) -1]◆Forwarding Delay — The maximum time (in seconds) this device waits 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 a discarding state; otherwise, temporary data loops might result. (Default: 15 seconds; Range: 1-30 seconds)Minimum: The higher of 1 or [(Max. Message Age / 2) + 1]Maximum: 30Ethernet InterfaceSets STP settings for the Ethernet port.◆Link Path Cost — This parameter is used by the STP to determine the best path between devices. Therefore, lower values should be assigned to ports attached to faster media, and higher values assigned to ports with slower media. (Path cost takes precedence over port priority.) (Default: 4; Range: 1-65535)◆Link Port Priority — Defines the priority used for this port in the Spanning Tree Protocol. If the path cost for all ports on a switch are the same, the port with the highest priority (i.e., lowest value) will be configured as an active link in the spanning tree. This makes a port with higher priority less likely to be blocked if the Spanning Tree Protocol is detecting network loops. Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be enabled.

–  49  –4Management SettingsThis chapter describes management access settings on the access point. It includes the following sections:◆“Remote Management Settings” on page 49◆“Access Limitation” on page 51◆“Simple Network Management Protocol” on page 52Remote Management SettingsThe Web, Telnet, and SNMP management interfaces are enabled and open to all IP addresses by default. To provide more security for management access to the access point, specific interfaces can be disabled and management restricted to a single IP address or a limited range of IP addresses.Once you specify an IP address or range of addresses, access to management interfaces is restricted to the specified addresses. If anyone tries to access a management interface from an unauthorized address, the access point will reject the connection.Telnet is a remote management tool that can be used to configure the access point from anywhere in the network. However, Telnet is not secure from hostile attacks. The Secure Shell (SSH) can act as a secure replacement for Telnet. The SSH protocol uses generated public keys to encrypt all data transfers passing between the access point and SSH-enabled management station clients and ensures that data traveling over the network arrives unaltered. Clients can then securely use the local user name and password for access authentication.Note that SSH client software needs to be installed on the management station to access the access point for management via the SSH protocol.Both HTTP and HTTPS service can be enabled independently. If you enable HTTPS, you must indicate this in the URL: https://device:port_number]When you start HTTPS, the connection is established in this way:◆The client authenticates the server using the server’s digital certificate.◆The client and server negotiate a set of security protocols to use for the connection.

(Default: disabled)Simple Network Management ProtocolSimple Network Management Protocol (SNMP) is a communication protocol designed specifically for managing devices on a network. Equipment commonly managed with SNMP includes switches, routers and host computers. SNMP is typically used to configure these devices for proper operation in a network environment, as well as to monitor them to evaluate performance or detect potential problems.Managed devices supporting SNMP contain software, which runs locally on the device and is referred to as an agent. A defined set of variables, known as managed objects, is maintained by the SNMP agent and used to manage the device. These objects are defined in a Management Information Base (MIB) that provides a standard presentation of the information controlled by the agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the network.The access point includes an onboard agent that supports SNMP versions 1, 2c, and 3 clients. This agent continuously monitors the status of the access point, as well as the traffic passing to and from wireless clients. A network management station can access this information using SNMP management software that is compliant with MIB II. To implement SNMP management, the access point must first have an IP address and subnet mask, configured either manually or dynamically. Access to the onboard agent using SNMP v1 and v2c is controlled by community strings. To communicate with the access point, the management station must first submit a valid community string for authentication.Access to the access point using SNMP v3 provides additional security features that cover message integrity, authentication, and encryption; as well as controlling notifications that are sent to specified user targets.SNMP Basic Settings The access point  SNMP agent must be enabled to function (for versions 1, 2c, and 3 clients). Management access using SNMP v1 and v2c also requires community

Trap notifications can be enabled and sent to up to four management stations.Figure 21:  SNMP Basic SettingsThe following items are displayed on this page:◆SNMP — Enables or disables SNMP management access and also enables the access point to send SNMP traps (notifications). (Default: Disable)◆System Location — A text string that describes the system location. (Maximum length: 255 characters)◆System Contact — A text string that describes the system contact. (Maximum length: 255 characters)◆Read-Only Community — Defines the SNMP community access string that has read-only access. Authorized management stations are only able to retrieve MIB objects. (Maximum length: 23 characters, case sensitive; Default: public)◆Read-Write Community — Defines the SNMP community access string that has read/write access.

When there are more subtree IDs than bits in the mask, the mask is padded with ones.◆View List – Shows the currently configured object identifiers of branches within the MIB tree that define the SNMP view.Creating GroupsAn SNMPv3 group sets the access policy for its assigned users, restricting them to specific read, write, and notify views. You can create new groups to map a set of SNMP users to SNMP views.◆Group Name – The name of the SNMP group. (Range: 1-32 characters)◆Security Level – The security level used for the group:■noAuthNoPriv – There is no authentication or encryption used in SNMP communications.■AuthNoPriv – SNMP communications use authentication, but the data is not encrypted.■AuthPriv – SNMP communications use both authentication and encryption.◆Read View – The configured view for read access. (Range: 1-32 characters)◆Write View – The configured view for write access. (Range: 1-32 characters)SNMPv3 Users The access point allows multiple SNMP v3 users to be configured. Each SNMPv3 user is defined by a unique name. Users must be configured with a specific security level and assigned to a group. The SNMPv3 group restricts users to a specific read, write, or notify view.Figure 24:  Configuring SNMPv3 Users
Chapter 4  |  Management SettingsSimple Network Management Protocol–  57  –The following items are displayed on this page:◆User Name — The SNMPv3 user name. (32 characters maximum)◆Group — The SNMPv3 group name.◆Auth Type — The authentication type used for the SNMP user; either MD5 or none. When MD5 is selected, enter a password in the corresponding Passphrase field.◆Auth Passphrase — The authentication password or key associated with the authentication and privacy settings. A minimum of eight plain text characters is required.◆Priv Type — The data encryption type used for the SNMP user; either DES or none. When DES is selected, enter a key in the corresponding Passphrase field.◆Priv Passphrase — The password or key associated with the authentication and privacy settings. A minimum of eight plain text characters is required.◆Action — Click the Add button to add a new user to the list. Click the edit button to change details of an existing user. Click the Del button to remove a user from the list.Note: Users must be assigned to groups that have the same security levels. For example, a user who has “Auth Type” and “Priv Type” configured to MD5 and DES respectively (that it, uses both authentication and data encryption) must be assigned to the RWPriv group. If this same user were instead assigned to the read-only (RO) group, the user would not be able to access the database.SNMPv3 Targets An SNMP v3 notification Target ID is specified by the SNMP v3 user, IP address, and UDP port. A user-defined filter can also be assigned to specific targets to limit the notifications received to specific MIB objects. (Note that the filter must first be configured. See “SNMPv3 Notification Filters” on page 58.)To configure a new notification receiver target, define the parameters and select a filter, if required. Note that the SNMP v3 user name must first be defined (See “SNMPv3 Users” on page 56.)

(Maximum length: 32 characters)◆Subtree — Specifies MIB subtree to be filtered. The MIB subtree must be defined in the form “.1.3.6.1” and always start with a “.”.◆Type — Indicates if the filter is to “include” or “exclude” the MIB subtree objects from the filter. Note that MIB objects included in the filter are not sent to the receiving target and objects excluded are sent. By default all traps are sent, so you can first use an “include” filter entry for all trap objects. Then use “exclude” entries for the required trap objects to send to the target. Note that the filter entries are applied in the sequence that they are defined.◆Action — Adds the notification filter.

It includes the following sections:◆“Local Bridge Filter” on page 60◆“Link Layer Discovery Protocol” on page 61◆“Access Control Lists” on page 63◆“Link Integrity” on page 66Local Bridge FilterThe access point can employ network traffic frame filtering to control access to network resources and increase security. You can prevent communications between wireless clients and prevent access point management from wireless clients. Also, you can block specific Ethernet traffic from being forwarded by the access point.The Local Bridge Filter sets the global mode for wireless-to-wireless communications between clients associated to Virtual AP (VAP) interfaces on the access point. (Default: Disabled)Figure 27:  Local Bridge FilterThe following items are displayed on this page:◆Disabled — All clients can communicate with each other through the access point.
Chapter 5  |  Advanced SettingsLink Layer Discovery Protocol–  61  –◆Prevent Intra VAP client communication — When enabled, clients associated with a specific VAP interface cannot establish wireless communications with each other. Clients can communicate with clients associated to other VAP interfaces.◆Prevent Inter and Intra VAP client communication — When enabled, clients cannot establish wireless communications with any other client, either those associated to the same VAP interface or any other VAP interface.Link Layer Discovery ProtocolThis page allows you to configure the Link Layer Discovery Protocol (LLDP). LLDP allows devices in the local broadcast domain to share information about themselves. LLDP-capable devices periodically transmit information in messages called Type Length Value (TLV) fields to neighbor devices. Advertised information is represented in Type Length Value (TLV) format according to the IEEE 802.1ab standard, and can include details such as device identification, capabilities and configuration settings.This information can be used by SNMP applications to simplify troubleshooting, enhance network management, and maintain an accurate network topology.Figure 28:  LLDP SettingsThe following items are displayed on this page:◆Disable/Enable — Disables/Enables LLDP on the access point.◆Message Transmission Hold Time — Configures the time-to-live (TTL) value sent in LLDP advertisements as shown in the formula below. (Range: 2-10; Default: 4)
Chapter 5  |  Advanced SettingsLink Layer Discovery Protocol–  62  –The time-to-live tells the receiving LLDP agent how long to retain all information pertaining to the sending LLDP agent if it does not transmit updates in a timely manner. TTL in seconds is based on the following rule: (Transmission Interval * Hold time) ≤ 65536. Therefore, the default TTL is 4*30 = 120 seconds.◆Message Transmission Interval (seconds) — Configures the periodic transmit interval for LLDP advertisements. (Range: 5-32768 seconds; Default: 30 seconds)This attribute must comply with the following rule: (Transmission Interval * Hold Time) ≤ 65536, and Transmission Interval >= (4 * Delay Interval)◆ReInitial Delay Time (seconds) — Configures the delay before attempting to re-initialize after LLDP ports are disabled or the link goes down. (Range: 1-10 seconds; Default: 2 seconds)When LLDP is re-initialized on a port, all information in the remote systems LLDP MIB associated with this port is deleted.◆Transmission Delay Value (seconds) — Configures a delay between the successive transmission of advertisements initiated by a change in local LLDP MIB variables. (Range: 1-8192 seconds; Default: 4 seconds)The transmit delay is used to prevent a series of successive LLDP transmissions during a short period of rapid changes in local LLDP MIB objects, and to increase the probability that multiple, rather than single changes, are reported in each transmission.This attribute must comply with the rule: (4 * Delay Interval) ≤ Transmission Interval
Chapter 5  |  Advanced SettingsAccess Control Lists–  63  –Access Control ListsAccess Control Lists allow you to configure a list of wireless client MAC addresses that are not authorized to access the network. A database of MAC addresses can be configured locally on the access point.Source AddressSettingsThe ACL Source Address Settings page enables traffic filtering based on the source MAC address in the data frame.Figure 29:  Source ACLsThe following items are displayed on this page:◆SA Status — Enables network traffic with specific source MAC addresses to be filtered (dropped) from the access point.◆MAC Address — Specifies a source MAC address to filter, in the form xx.xx.xx.xx.xx.xx, or xx-xx-xx-xx-xx-xx.◆Action — Selecting “Add” adds a new MAC address to the filter list, selecting delete removes the specified MAC address.◆Number — Specifies the number associated with the MAC address.◆MAC Address — Displays the configured source MAC address.

(Default: Disabled)Figure 31:  Ethernet Type FilterThe following items are displayed on this page:◆Disabled — Access point does not filter Ethernet protocol types.◆Enabled — Access point filters Ethernet protocol types based on the configuration of protocol types in the filter table. If the status of a protocol is set to “ON,” the protocol is filtered from the access point.◆Local Management — Describes the Ethernet filter type.◆ISO Designator — Describes the ISO Designator identifier.◆Filter Status — Turns the filter on or off.
Chapter 5  |  Advanced SettingsLink Integrity–  66  –Link IntegrityThe AP provides a link integrity feature that can be used to ensure that wireless clients are connected to resources on the wired network. The AP does this by periodically sending Ping messages to a host device in the wired Ethernet network. If the AP detects that the connection to the host has failed, it can disable the radio interfaces, forcing clients to find and associate with another AP. When the connection to the host is restored, the AP re-enables the radio interfaces.Figure 32:  Link IntegrityThe following items are displayed on this page:◆Link Integrity — Enables the feature. (Default: Disabled)◆Destination IP — The link host IP address on the wired network to which Ping messages are sent. (Default: 192.168.2.254)◆Detect Interval — The interval time between each Ping sent to the host IP address.(Range: 10-86400 seconds; Default: 60 seconds)◆Response Timeout — The time to wait for a response to a Ping message. (Range: 1-10 seconds; Default: 2 seconds)◆Retry Count if no response — The number of consecutive failed Ping counts before the link is determined as lost. (Range: 1-99; Default: 5)◆Link Fail Action — When a link integrity test fails you can optionally disable either radio interface. Note that the shutdown action does not apply for a VAP interface set to WDS station mode. (Default: Disabled)

Chapter 6  |  Wireless SettingsAuthentication–  68  –AuthenticationWireless clients can be authenticated for network access by checking their MAC address against the local database configured on the access point, or by using a database configured on a central RADIUS server. Alternatively, authentication can be implemented using the IEEE 802.1X network access control protocol.You can configure a list of the MAC addresses for wireless clients that are authorized to access the network. This provides a basic level of authentication for wireless clients attempting to gain access to the network. A database of authorized MAC addresses can be stored locally on the access point or remotely on a central RADIUS server. (Default: Local MAC)Local MACAuthenticationConfigures the local MAC authentication database. The MAC database provides a mechanism to take certain actions based on a wireless client’s MAC address. The MAC list can be configured to allow or deny network access to specific clients.Figure 33:  Local AuthenticationThe following items are displayed on Authentication page:MAC Authentication — Selects between, disabled, Local MAC authentication and RADIUS authentication.
Chapter 6  |  Wireless SettingsAuthentication–  69  –◆Local MAC — The MAC address of the associating station is compared against the local database stored on the access point. The Local MAC Authentication section enables the local database to be set up.◆System Default — Specifies a default action for all unknown MAC addresses (that is, those not listed in the local MAC database).■Deny: Blocks access for all MAC addresses except those listed in the local database as “Allow.” ■Allow: Permits access for all MAC addresses except those listed in the local database as “Deny.”◆MAC Authentication Settings — Enters specified MAC addresses and permissions into the local MAC database.■MAC Address: Physical address of a client. Enter six pairs of hexadecimal digits separated by hyphens; for example, 00-90-D1-12-AB-89.■Permission: Select Allow to permit access or Deny to block access.■Add/Delete: Adds or deletes the specified MAC address and permission setting into or from the local database.◆MAC Authentication Table — Displays current entries in the local MAC database.RADIUS MACAuthenticationThe MAC address of the associating station is sent to a configured RADIUS server for authentication. When using a RADIUS authentication server for MAC address authentication, the server must first be configured on the RADIUS page.Figure 34:  RADIUS AuthenticationThe following items are displayed on Authentication page:MAC Authentication — Selects between, disabled, Local MAC authentication and RADIUS authentication.
Chapter 6  |  Wireless SettingsAuthentication–  70  –◆RADIUS MAC — The MAC address of the associating station is compared against the RADIUS server database. The RADIUS MAC Authentication section enables the RADIUS database to be set up.◆Session Timeout — The time period after which a connected client must be re-authenticated. During the re-authentication process of verifying the client’s credentials on the RADIUS server, the client remains connected the network. Only if re-authentication fails is network access blocked. (Default: 0 means disabled; Range: 30-65535 seconds)
Chapter 6  |  Wireless SettingsRadio Settings–  71  –Radio SettingsThe IEEE 802.11n wireless interfaces include configuration options for radio signal characteristics and wireless security features.The AP can operate in several radio modes, mixed 802.11b/g/n (2.4 GHz), or mixed 802.11a/n (5 GHz). Note that the radios can operate at 2.4 GHz and 5 GHz at the same time. The web interface identifies the radio configuration pages as:◆Radio 0 — the 2.4 GHz 802.11b/g/n radio interface◆Radio 1 — the 5 GHz 802.11a/n radio interfaceEach radio supports 16 virtual access point (VAP) interfaces, referred to as VAP 0 ~ VAP 15. Each VAP functions as a separate access point, and can be configured with its own Service Set Identification (SSID) and security settings. However, most radio signal parameters apply to all VAP interfaces. The configuration options are nearly identical, and are therefore both covered in this section of the manual. Traffic to specific VAPs can be segregated based on user groups or application traffic. The clients associate with each VAP in the same way as they would with separate physical access points. The AP supports up to a total of 127 wireless clients across all VAP interfaces per radio. Figure 35:  Radio Settings
Chapter 6  |  Wireless SettingsRadio Settings–  72  –The following items are displayed on this page:◆High Throughput Mode — The access point provides a channel bandwidth of 20 MHz by default giving an 802.11g connection speed of 54 Mbps and a 802.11n connection speed of up to 108 Mbps, and ensures backward compliance for slower 802.11b devices. Setting the HT Channel Bandwidth to 40 MHz increases connection speed for 802.11n up to 300 Mbps. HT40plus indicates that the secondary channel is above the primary channel. HT40minus indicates that the secondary channel is below the primary channel.(Default: HT20; Range:HT20, HT40PLUS, HT40MINUS)◆Radio Channel — The radio channel that the access point uses to communicate with wireless clients. When multiple access points are deployed in the same area, set the channel on neighboring access points at least five channels apart to avoid interference with each other. For example, for 11g/n HT20 mode you can deploy up to three access points in the same area using channels 1, 6, 11. Note that wireless clients automatically set the channel to the same as that used by the access point to which it is linked. (The available channels are dependent on the Radio Mode, High Throughput Mode, and Country Code settings.)◆Auto Channel — Selecting Auto Select enables the access point to automatically select an unoccupied radio channel.◆Interference Channel Recover — Rescans all channels when interference is detected on the current channel, and then changes to a clear channel. (Default: Disabled)◆Antenna — Sets the antenna options for this AP to “system default.”◆Transmit Power — Adjusts the power of the radio signals transmitted from the access point. The higher the transmission power, the farther the transmission range. Power selection is not just a trade off between coverage area and maximum supported clients. You also have to ensure that high-power signals do not interfere with the operation of other radio devices in the service area. (Range - Percentage mode: min, 12.5%, 25%, 50%, 100%; Default: 100%)(Range - dBm mode: 3-20 dBm; Default: 18 dBm)◆Maximum Association Clients — The total maximum number of clients that may associate with the radio. (Range: 1-127; Default: 127)◆Radio Mode — Defines the radio operation mode. ■Radio 0 (2.4 GHz Radio) — Default: 11n (g compatible); Options: 11n (b&g compatible), 11n (g compatible).■Radio 1 (5 GHz Radio) — Default: 11n; Options: 11n (a compatible), 11n.
Chapter 6  |  Wireless SettingsRadio Settings–  73  –Note: Enabling the AP to communicate with 802.11b/g clients in both 802.11b/g/n Mixed and 802.11n modes also requires that HT Operation be set to HT20.◆Preamble Length — The radio preamble (sometimes called a header) is a section of data at the head of a packet that contains information that the wireless device and client devices need when sending and receiving packets. You can set the radio preamble to long or short. A short preamble improves throughput performance, whereas a long preamble is required when legacy wireless devices are part of your network.◆Beacon Interval — The rate at which beacon signals are transmitted from the access point. The beacon signals allow wireless clients to maintain contact with the access point. They may also carry power-management information. (Range: 40-3500 TUs; Default: 100 TUs)◆Data Beacon Rate (DTIM) — The rate at which stations in sleep mode must wake up to receive broadcast/multicast transmissions. Known also as the Delivery Traffic Indication Map (DTIM) interval, it indicates how often the MAC layer forwards broadcast/multicast traffic, which is necessary to wake up stations that are using Power Save mode. The default value of 2 indicates that the access point will save all broadcast/multicast frames for the Basic Service Set (BSS) and forward them after every second beacon. Using smaller DTIM intervals delivers broadcast/multicast frames in a more timely manner, causing stations in Power Save mode to wake up more often and drain power faster. Using higher DTIM values reduces the power used by stations in Power Save mode, but delays the transmission of broadcast/multicast frames. (Range: 1-255 beacons; Default: 1 beacon)◆RTS Threshold — Sets the packet size threshold at which a Request to Send (RTS) signal must be sent to a receiving station prior to the sending station starting communications. The access point sends RTS frames to a receiving station to negotiate the sending of a data frame. After receiving an RTS frame, the station sends a CTS (clear to send) frame to notify the sending station that it can start sending data.If the RTS threshold is set to 1, the access point always sends RTS signals. If set to 2346, the access point never sends RTS signals. If set to any other value, and the packet size equals or exceeds the RTS threshold, the RTS/CTS (Request to Send / Clear to Send) mechanism will be enabled.The access points contending for the medium may not be aware of each other. The RTS/CTS mechanism can solve this “Hidden Node Problem.” (Range: 1-2346 bytes: Default: 2346 bytes)◆Short Guard Interval — The 802.11n draft specifies two guard intervals: 400ns (short) and 800ns (long).  Support of the 400ns GI is optional for transmit and receive. The purpose of a guard interval is to introduce immunity to
Chapter 6  |  Wireless SettingsRadio Settings–  74  –propagation delays, echoes, and reflections to which digital data is normally very sensitive. Enabling the Short Guard Interval sets it to 400ns. (Default: Disabled)◆Aggregate MAC Protocol Data Unit (A-MPDU) — Enables / disables the sending of this four frame packet header for statistical purposes. (Default: Enabled)◆A-MPDU Length Limit (1024-65535) — Defines the A-MPDU length. (Default: 65535 bytes; Range: 1024-65535 bytes)◆Aggregate MAC Service Data Unit (A-MSDU) — Enables / disables the sending of this four frame packet header for statistical purposes. (Default: Enabled)◆Disable HT20/HT40 Coexistance — Prevents 802.11n 20 MHz and 40 MHz channel bandwidths from operating together in the same network. (Default: Disabled)◆Antenna Selection — Sets the radio to use one or both antennas. (Options: Left, Right, Right+Left; Default: Right+Left)◆Minimum CCK Rate — (2.4 GHz radio only) The minimum CCK data rate at which the AP transmits packets on the wireless interface. (Options: 1, 2, 5.5, 11 Mbps; Default 1 Mbps)◆Minimum OFDM Rate — The minimum OFDM data rate at which the AP transmits packets on the wireless interface. (Range: 6, 9, 12, 18, 24, 36, 48, 54 Mbps; Default 6 Mbps)◆Minimum Single Stream Rate — The minimum 802.11n single stream data rate at which the AP transmits packets on the wireless interface. (Range: MCS0-MCS7; Default MCS0)◆Minimum Double Stream Rate — The minimum 802.11n double stream data rate at which the AP transmits packets on the wireless interface. (Range: MCS8-MCS15; Default MCS8)◆Long Distance Setting — When you have long-distance links in the wireless network, some timing parameters require an adjustment to maintain communications.Enter the approximate distance (in meters) of the client from the AP. Click on the “Show Reference Data” button to compute a set of recommended values for SlotTime, ACKTimeOut and CTSTimeOut. You can use the recommended values or enter your own values that work for your specific environment.◆Set Radio — Sets all entered parameters.
Chapter 6  |  Wireless SettingsVirtual Access Points (VAPs)–  75  –Virtual Access Points (VAPs)The AP supports up to 16 virtual access point (VAP) interfaces per radio, numbered 0 to 15. Each VAP functions as a separate access point, and can be configured with its own Service Set Identification (SSID) and security settings. However, most radio signal parameters apply to all VAP interfaces. The VAPs function similar to a VLAN, with each VAP mapped to its own default VLAN ID. Traffic to specific VAPs can be segregated based on user groups or application traffic. All VAPs can support up to a total of 127 wireless clients, whereby the clients associate with each VAP the same way as they would with separate physical access points. Note: The radio channel settings for the access point are limited by local regulations, which determine the number of channels that are available. See “Operating Channels” on page 46 for additional information on the maximum number channels available.Figure 36:  VAP SettingsThe following items are displayed on this page:◆VAP Number — The number associated with the VAP, 0-15.◆SSID — The name of the basic service set provided by a VAP interface. Clients that want to connect to the network through the access point must set their SSID to the same as that of an access point VAP interface. (Default: EAP9112A_11BGN_# (0 to 15); Range: 1-32 characters)
Chapter 6  |  Wireless SettingsVirtual Access Points (VAPs)–  76  –◆Enable — Enables the specified VAP. (Default: Disabled)◆Status — Displays the mode of the VAP. The default is set to "AP," for normal access point services. ◆Edit Setting — Click to open the page to configure basic and security settings for the selected VAP.◆QoS Setting — Click to open the page to configure QoS settings for the selected VAP.◆Bandwidth Setting — Click to open the page to configure bandwidth control for the selected VAP.VAP Basic Settings Sets the basic operating mode and other settings for the VAP. Each VAP can operate in one of three modes; normal AP mode, WDS-AP bridge AP mode, or WDS-STA bridge station mode. The default mode is AP for the VAP to support normal access point services.Note: For more information and examples for setting up WDS networks, see “WDS Setup Examples” on page 45.Note that the Basic Settings are the same for both AP and WDS-AP modes.Figure 37:  VAP Basic SettingsThe following items are displayed on this page:◆Closed System — When enabled, the VAP does not include its SSID in beacon messages. Nor does it respond to probe requests from clients that do not include a fixed SSID. (Default: Disable)
Chapter 6  |  Wireless SettingsVirtual Access Points (VAPs)–  77  –◆Mode — Selects the mode in which the VAP will function.■AP Mode: The VAP provides services to clients as a normal access point.■WDS-AP Mode: The VAP operates as an access point in WDS mode, which accepts connections from APs in WDS-STA mode.■WDS-STA Mode: The VAP operates as a client station in WDS mode, which connects to an access point VAP in WDS-AP mode. The user needs to specify the MAC address of the access point in WDS-AP mode to which it intends to connect.◆Maximum Association Clients — The total maximum number of clients that may associate with this VAP. The maximum is 127, which is the total associated clients for all VAP interfaces. (Range: 1 to 127; Default 64)◆WLAN Client Association Preemption — When enabled, the AP applies a priority order for associating clients when the maximum clients for the VAP has been reached. The priority order is 11n clients, 11a/g clients, then 11b clients. When the association pool for the VAP is full and the AP receives an association request from a high-priority (11n) client, the AP sends a disassociation to a lower priority client (11a/g or 11b) in order to be able to associate the high-priority client. If there are no lower-priority clients to disassociate, the AP will reject the association request. (Default: Disabled)◆Association Timeout Interval — The idle time interval (when no frames are sent) after which a client is disassociated from the VAP interface. (Range: 5-60 minutes; Default: 30 minutes)◆Authentication Timeout Interval — The time within which the client should finish authentication before authentication times out. (Range: 5-60 minutes; Default: 60 minutes)◆Default VLAN ID — The VLAN ID assigned to wireless clients associated to the VAP interface that are not assigned to a specific VLAN by RADIUS server configuration. (Default: 1)◆DHCP Relay Server — The IP address of the DHCP relay server. 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 access point’s DHCP relay agent is enabled, received client requests can be forwarded directly by the access point to a known DHCP server on another subnet. Responses from the DHCP server are returned to the access point, which then broadcasts them back to clients. (Default: 0.0.0.0 (disabled))◆SSID — The service set identifier for the VAP.
Chapter 6  |  Wireless SettingsVirtual Access Points (VAPs)–  78  –◆Multicast Enhancement — When a wireless client joins a multicast group, this feature converts multicast packets to unicast packets to improve multicast video quality. WDS-STA Mode Describes additional basic VAP settings when functioning in WDS-STA mode.Figure 38:  WDS-STA ModeThe following items are displayed in the VAP Basic Settings when WDS-AP mode is selected:◆WDS-AP (Parent) SSID — The SSID of the VAP on the connecting access point that is set to WDS-AP mode.◆WDS-AP (Parent) MAC — The MAC address of the VAP on the connecting access point that is set to WDS-AP mode.Wireless SecuritySettingsDescribes the wireless security settings for each VAP, including association mode, encryption, and authentication.Note: For VAPs set to WDS-AP or WDS-STA mode, the security options are limited to WPA-PSK and WPA2-PSK only.Figure 39:  Configuring VAPs - Security Settings
Chapter 6  |  Wireless SettingsVirtual Access Points (VAPs)–  79  –The following items are available for VAP security:◆Association Mode — Defines the mode with which the VAP will associate with clients.■Open System: The VAP is configured by default as an “open system,” which broadcasts a beacon signal including the configured SSID. Wireless clients with an SSID setting of “any” can read the SSID from the beacon and automatically set their SSID to allow immediate connection. ■WPA: WPA employs a combination of several technologies to provide an enhanced security solution for 802.11 wireless networks.■WPA-PSK: For enterprise deployment, WPA requires a RADIUS authentication server to be configured on the wired network. However, 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. The Pre-Shared Key mode uses a common password for user authentication that is manually entered on the access point and all wireless clients. The PSK mode uses the same TKIP packet encryption and key management as WPA in the enterprise, providing a robust and manageable alternative for small networks.■WPA2: WPA was introduced as an interim solution for the vulnerability of WEP pending the ratification of the IEEE 802.11i wireless security standard. In effect, the WPA security features are a subset of the 802.11i standard. WPA2 includes the now ratified 802.11i standard, but also offers backward compatibility with WPA. Therefore, WPA2 includes the same 802.1X and PSK modes of operation and support for TKIP encryption. ■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.◆Encryption Method — Selects an encryption method for the global key used for multicast and broadcast traffic, which is supported by all wireless clients.■WEP: WEP is used as the multicast encryption cipher. You should select WEP only when both WPA and WEP clients are supported. ■TKIP: TKIP is used as the multicast encryption cipher.■AES-CCMP: AES-CCMP is used as the multicast encryption cipher. AES-CCMP is the standard encryption cipher required for WPA2.
Chapter 6  |  Wireless SettingsVirtual Access Points (VAPs)–  80  –◆802.1X — The access point supports 802.1X authentication only for clients initiating the 802.1X authentication process (i.e., the access point does not initiate 802.1X authentication). For clients initiating 802.1X, only those successfully authenticated are allowed to access the network. For those clients not initiating 802.1X, access to the network is allowed after successful wireless association with the access point. The 802.1X mode allows access for clients not using WPA or WPA2 security.◆Pre-Authentication — When using WPA2 over 802.1X, pre-authentication can be enabled, which allows clients to roam to a new access point and be quickly associated without performing full 802.1X authentication. (Default: Disabled)◆802.1x Reauthentication Time — The time period after which a connected client must be re-authenticated. During the re-authentication process of verifying the client’s credentials on the RADIUS server, the client remains connected the network. Only if re-authentication fails is network access blocked. (Range: 0-65535 seconds; Default: 0 means disabled)Wired EquivalentPrivacy (WEP)WEP provides a basic level of security, preventing unauthorized access to the network, and encrypting data transmitted between wireless clients and the VAP. WEP uses static shared keys (fixed-length hexadecimal or alphanumeric strings) that are manually distributed to all clients that want to use the network.WEP is the security protocol initially specified in the IEEE 802.11 standard for wireless communications. Unfortunately, WEP has been found to be seriously flawed and cannot be recommended for a high level of network security. For more robust wireless security, the access point provides Wi-Fi Protected Access (WPA) and WPA2 for improved data encryption and user authentication.Setting up shared keys enables the basic IEEE 802.11 Wired Equivalent Privacy (WEP) on the access point to prevent unauthorized access to the network.If you choose to use WEP shared keys instead of an open system, be sure to define at least one static WEP key for user authentication and data encryption. Also, be sure that the WEP shared keys are the same for each client in the wireless network. All clients share the same keys, which are used for user authentication and data encryption. Up to four keys can be specified.

(Range: 100-12000 Kbytes per second; Default: 100 Kbytes per second)◆Bandwidth Control on Downlink Setting — Enables the rate limiting of traffic from the wired network as it is passed to the VAP interface. You can set a maximum rate in kbytes per second. (Range: 100-12000 Kbytes per second; Default: 100 Kbytes per second)Rogue AP DetectionA “rogue AP” is either an access point that is not authorized to participate in the wireless network, or an access point that does not have the correct security configuration. Rogue APs can allow unauthorized access to the network, or  fool client stations into mistakenly associating with them and thereby blocking access to network resources. The access point can be configured to periodically scan all radio channels and find other access points within range. A database of nearby access points is maintained where any rogue APs can be identified. Rogue access points can be identified by unknown BSSID (MAC address).
Chapter 6  |  Wireless SettingsRogue AP Detection–  85  –Figure 44:  Rogue AP DetectionThe following items are displayed on this page:◆AP Scan Setting — Enables the periodic scanning for other nearby access points. (Default: Disable)◆Scan Interval — Sets the time between each rogue AP scan. (Range: 15 -65535 seconds; Default: 7200 seconds)◆Scan Duration — Sets the length of time for each rogue AP scan. A long scan duration time will detect more access points in the area, but causes more disruption to client access. (Range: 10 -150 milliseconds; Default: 150 milliseconds)◆First Scan Delay — Delays the start of rogue AP scanning after enabling the feature or booting the AP. (Range: 0 -65535 seconds; Default: 65535 seconds)◆Friendly AP — Allows you to enter the MAC address/Basic Service Set Identifier (BSSID) of known APs in the network. These MAC addresses will be filtered out of the list of detected APs during a scan.◆Friendly AP MAC Table — Displays the MAC addresses of known APs in the network.
Chapter 6  |  Wireless SettingsWi-Fi Multimedia (WMM)–  86  –◆Rogue AP Scan Result — Displays information of unknown APs detected within the range of the AP running the scan.◆Friendly Active AP Scan Result — Displays information of known APs detected within the range of the AP running the scan.  ◆Start Instant Scan — Starts an immediate rogue AP scan on the radio interface. (Default: Disable)Note: While the access point scans a channel for rogue APs, wireless clients will not be able to connect to the access point. 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.Wi-Fi Multimedia (WMM)Wireless networks offer an equal opportunity for all devices to transmit data from any type of application. Although this is acceptable for most applications, multimedia applications (with audio and video) are particularly sensitive to the delay and throughput variations that result from this “equal opportunity” wireless access method. For multimedia applications to run well over a wireless network, a Quality of Service (QoS) mechanism is required to prioritize traffic types and provide an “enhanced opportunity” wireless access method.The access point implements QoS using the Wi-Fi Multimedia (WMM) standard. Using WMM, the access point is able to prioritize traffic and optimize performance when multiple applications compete for wireless network bandwidth at the same time. WMM employs techniques that are a subset of the IEEE 802.11e QoS standard and it enables the access point to interoperate with both WMM-enabled clients and other devices that may lack any WMM functionality.Access Categories — 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 “WMM Access Categories” on page 87). The direct mapping of the four ACs to 802.1D priorities is specifically intended to facilitate inter operability with other wired network QoS policies. While the four ACs are specified for specific types of traffic, WMM allows the priority levels to be configured to match any network-wide QoS policy. WMM also specifies a protocol that access points can use to communicate the configured traffic priority levels to QoS-enabled wireless clients.
Chapter 6  |  Wireless SettingsWi-Fi Multimedia (WMM)–  87  –WMM Operation — WMM uses traffic priority based on the four ACs; Voice, Video, Best Effort, and Background. The higher the AC priority, the higher the probability that data is transmitted. When the access point forwards traffic, WMM adds data packets to four independent transmit queues, one for each AC, depending on the 802.1D priority tag of the packet. Data packets without a priority tag are always added to the Best Effort AC queue. From the four queues, an internal “virtual” collision resolution mechanism first selects data with the highest priority to be granted a transmit opportunity. Then the same collision resolution mechanism is used externally to determine which device has access to the wireless medium. For each AC queue, the collision resolution mechanism is dependent on two timing parameters:◆AIFSN (Arbitration Inter-Frame Space Number), a number used to calculate the minimum time between data frames◆CW (Contention Window), a number used to calculate a random backoff timeAfter a collision detection, a backoff wait time is calculated. The total wait time is the sum of a minimum wait time (Arbitration Inter-Frame Space, or AIFS) determined from the AIFSN, and a random backoff time calculated from a value selected from zero to the CW. The CW value varies within a configurable range. It starts at CWMin and doubles after every collision up to a maximum value, CWMax. After a successful transmission, the CW value is reset to its CWMin value.Table 2: WMM Access CategoriesAccess CategoryWMM DesignationDescription 802.1D TagsAC_VO (AC3) Voice Highest priority, minimum delay. Time-sensitive data such as VoIP (Voice over IP) calls. 7, 6AC_VI (AC2) Video High priority, minimum delay. Time-sensitive data such as streaming video. 5, 4AC_BE (AC0) Best Effort Normal priority, medium delay and throughput. Data only affected by long delays.

Chapter 6  |  Wireless SettingsWi-Fi Multimedia (WMM)–  88  –Figure 45:  WMM Backoff Wait TimesFor high-priority traffic, the AIFSN and CW values are smaller. The smaller values equate to less backoff and wait time, and therefore more transmit opportunities.Figure 46:  QoSAIFS Random BackoffAIFS Random BackoffCWMin CWMaxCWMin CWMaxTimeHigh PriorityLow PriorityMinimum Wait Time Random Wait TimeMinimum Wait Time Random Wait Time

When enabled, the parameters for each AC queue will be employed on the access point and QoS capabilities are advertised to WMM-enabled clients. (Default: Disabled)■Disable: WMM is disabled.■Enable: WMM must be supported on any device trying to associated with the access point. Devices that do not support this feature will not be allowed to associate with the access point.◆WMM Acknowledge Policy — By default, all wireless data transmissions require the sender to wait for an acknowledgement from the receiver. WMM allows the acknowledgement wait time to be turned off for each Access Category (AC) 0-3. Although this increases data throughput, it can also result in a high number of errors when traffic levels are heavy.

The initial wait time is a random value between zero and the CWMin value. Specify the CWMin value in the range 0-15 microseconds. Note that the CWMin value must be equal or less than the CWMax value.■logCWMax (Maximum Contention Window): 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 CWMax value. Specify the CWMax value in the range 0-15 microseconds. Note that the CWMax value must be greater or equal to the CWMin value. ■AIFSN (Arbitration Inter-Frame Space): The minimum amount of wait time before the next data transmission attempt. Specify the AIFS value in the range 0-15 microseconds. ■TXOP Limit (Transmit Opportunity Limit): 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. Specify a value in the range 0-65535 microseconds.

–  109  –9Using the Command Line InterfaceWhen accessing the management interface for the over a direct connection to the console port, or via a Telnet connection, the access point can be managed by entering command keywords and parameters at the prompt. Using the access point’s command-line interface (CLI) is very similar to entering commands on a UNIX system.Console ConnectionTo access the AP through the console port, first set up a console connection to the AP. See “Console Port Connection” on page 19 for more information.At the console prompt, enter the user name and password. (The default user name is “admin” with no default password.) After the password is entered, the CLI displays the “SMC#” prompt. Example(none) login: adminPassword:Jan  1 11:33:13 login[1918]: root login on 'ttyS0'SMC#Note: Command examples shown later in this chapter abbreviate the console prompt to “AP” for simplicity.Enter the necessary commands to complete your desired tasks. When finished, exit the session with the “exit” command.
Chapter 9  |  Using the Command Line InterfaceTelnet Connection–  110  –Telnet ConnectionTelnet operates over the IP transport protocol. In this environment, your management station and any network device you want to manage over the network must have a valid IP address. If the access point does not acquire an IP address from a DHCP server, the default IP address used by the access point is 192.168.2.10.To access the AP through a Telnet session, you must first set the IP address for the AP, and set the default gateway if you are managing the AP from a different IP subnet. For example:AP#configureAP(config)#interface ethernetAP(if-ethernet)#ip address 10.1.0.1 255.255.255.0 10.1.0.254AP(if-ethernet)#After you configure the access point with an IP address, you can open a Telnet session by performing these steps.1. From the remote host, enter the Telnet command and the IP address of the device you want to access. 2. At the prompt, enter the user name and system password. The CLI will display the “AP#” prompt to show that you are using executive access mode (that is, Exec). (none) login: adminPassword:AP#3. Enter the necessary commands to complete your desired tasks. 4. When finished, exit the session with the “quit” or “exit” command. Note: You can open up to four sessions to the device through Telnet.
Chapter 9  |  Using the Command Line InterfaceEntering Commands–  111  –Entering CommandsThis section describes how to enter CLI commands.Keywords andArgumentsA CLI command is a series of keywords and arguments. Keywords identify a command, and arguments specify configuration parameters. For example, in the command “show interfaces ethernet,” show and interfaces are keywords, and ethernet is an argument that specifies the interface type.You can enter commands as follows:◆To enter a simple command, enter the command keyword. ◆To enter commands that require parameters, enter the required parameters after the command keyword. For example, to set a password for the administrator, enter:AP(config)#password admin tpschrisMinimumAbbreviationThe CLI will accept a minimum number of characters that uniquely identify a command. For example, the command “configure” can be entered as con. If an entry is ambiguous, the system will prompt for further input.CommandCompletionIf you terminate input with a Tab key, the CLI will print the remaining characters of a partial keyword up to the point of ambiguity. In the “configure” example, typing con followed by a tab will result in printing the command up to “configure.”Getting Help onCommandsYou can display a brief description of the help system by entering the help command. You can also display command syntax by following a command with the “?” character to list keywords or parameters.Showing Commands If you enter a “?” at the command prompt, the system will display the first level of keywords for the current configuration mode (Exec, Global Configuration, or Interface). You can also display a list of valid keywords for a specific command. For example, the command “show ?” displays a list of possible show commands:AP# show ?  APmanagement    Show management AP information.  authentication  Show Authentication parameters.  bridge          Show bridge.  config          Show current configuration.  event-log       Show event log on console.  filters         Show filters.  firmware-image  Show firmware images version.

For example, the logging command will log system messages to a host server. To disable logging, specify the no logging command. This guide describes the negation effect for all applicable commands.Using CommandHistoryThe CLI maintains a history of commands that have been entered. You can scroll back through the history of commands by pressing the up arrow key. Any command displayed in the history list can be executed again, or first modified and then executed. UnderstandingCommand ModesThe command set is divided into Exec and Configuration classes. Exec commands generally display information on system status or clear statistical counters. Configuration commands, on the other hand, modify interface parameters or enable certain functions. These classes are further divided into different modes. Available commands depend on the selected mode. You can always enter a question mark “?” at the prompt to display a list of the commands available for the
Chapter 9  |  Using the Command Line InterfaceEntering Commands–  113  –current mode. The command classes and associated modes are displayed in the following table:Exec CommandsWhen you open a new console session on an access point, the system enters Exec command mode. Only a limited number of the commands are available in this mode. You can access all other commands only from the configuration mode. To access Exec mode, open a new console session with the user name “admin.” The command prompt displays as “AP#” for Exec mode.(none) login: adminPassword: [system login password]AP#Configuration CommandsConfiguration commands are used to modify access point settings. These commands modify the running configuration and are saved in memory. The configuration commands are organized into four different modes:◆Global Configuration (GC) - These commands modify the system level configuration, and include commands such as system name and password. ◆Interface-Ethernet Configuration (IC-E) - These commands modify the Ethernet port configuration, and include command such as dns and ip.◆Interface-Wireless Configuration (IC-W) - These commands modify the wireless port configuration of global parameters for the radio, and include commands such as channel and beacon-interval.◆Interface-Wireless Virtual Access Point Configuration (IC-W-VAP) - These commands modify the wireless port configuration for each VAP, and include commands such as ssid and encryption.To enter the Global Configuration mode, enter the command configure in Exec mode. The system prompt will change to “AP(config)#” which gives you access privilege to all Global Configuration commands.Table 3: Command ModesClass ModeExec PrivilegedConfiguration GlobalInterface-ethernetInterface-wirelessInterface-wireless-vap
Chapter 9  |  Using the Command Line InterfaceEntering Commands–  114  –AP#configureAP(config)#To enter Interface mode, you must enter the “interface ethernet” while in Global Configuration mode. The system prompt will change to  “AP(if-ethernet)#,” or “AP(if-wireless 0)” indicating that you have access privileges to the associated commands. You can use the exit command to return to the Exec mode.AP(config)#interface ethernetAP(if-ethernet)#Command LineProcessingCommands are not case sensitive. You can abbreviate commands and parameters as long as they contain enough letters to differentiate them from any other currently available commands or parameters. You can use the Tab key to complete partial commands, or enter a partial command followed by the “?” character to display a list of possible matches.

–  149  –14 DHCP Relay CommandsDynamic Host Configuration Protocol (DHCP) can dynamically allocate an IP address and other configuration information to network clients that broadcast a request. To receive the broadcast request, the DHCP server would normally have to be on the same subnet as the client. However, when the access point’s DHCP relay agent is enabled, received client requests can be forwarded directly by the access point to a known DHCP server on another subnet. Responses from the DHCP server are returned to the access point, which then broadcasts them back to clients.dhcp-relay server This command configures the DHCP server address and enables the DHCP relay agent.Syntaxdhcp-relay server <ip_address>ip_address - IP address of the DHCP server.Default Setting 0.0.0.0 (disabled)Command Mode Interface Configuration (Wireless-VAP)Command Usage ◆For the DHCP relay agent to function, the DHCP server IP address must be configured.

–  173  –18 802.1X Authentication CommandsThe access point supports IEEE 802.1X access control for wireless clients. 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 access point 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.802.1x enable This command configures 802.1X as enabled for wireless clients.

Chapter 24  |  Wireless Interface Commands–  215  –Default Setting 1Command Mode Interface Configuration (Wireless)Command Usage ◆The Delivery Traffic Indication Map (DTIM) packet interval value indicates how often the MAC layer forwards broadcast/multicast traffic. This parameter is necessary to wake up stations that are using Power Save mode.◆The DTIM is the interval between two synchronous frames with broadcast/multicast information. The default value of 1 indicates that the access point will save all broadcast/multicast frames for the Basic Service Set (BSS) and forward them after every 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.ExampleAP(if-wireless 0)# dtim-period 10This setting has not been effective !If want to take effect, please execute make-RF-setting-effective command !AP(if-wireless 0)#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.Syntaxrts-threshold <threshold>threshold - Threshold packet size for which to send an RTS. (Range: 1-2346 bytes)Default Setting 2346Command Mode Interface Configuration (Wireless)
Chapter 24  |  Wireless Interface Commands–  216  –Command Usage ◆If the threshold is set to 1, the access point always sends RTS signals. If set to 2346, the access point never sends RTS signals. If set to any other value, and the packet size equals or exceeds the RTS threshold, the RTS/CTS (Request to Send / Clear to Send) mechanism will be enabled.◆The access point sends RTS frames to a receiving station to negotiate the sending of a data frame. After receiving an RTS frame, the station sends a CTS frame to notify the sending station that it can start sending data. ◆Access points contending for the wireless medium may not be aware of each other. The RTS/CTS mechanism can solve this “Hidden Node” problem.ExampleAP(if-wireless 0)# rts-threshold 1This setting has not been effective !If want to take effect, please execute make-RF-setting-effective command !AP(if-wireless 0)#ssid This command configures the service set identifier (SSID) of the VAP.Syntaxssid <string>string - The name of a basic service set supported by the access point.

Use the no form to disable the feature.Syntax[no] client-assoc-preemptDefault Setting DisabledCommand Mode Interface Configuration (Wireless-VAP)
Chapter 24  |  Wireless Interface Commands–  219  –Command Usage◆When enabled, the AP applies a priority order for associating clients when the maximum clients for the VAP has been reached. The priority order is 11n clients, 11a/g clients, then 11b clients. ◆When the association pool for the VAP is full and the AP receives an association request from a high-priority (11n) client, the AP sends a disassociation to a lower priority client (11a/g or 11b) in order to be able to associate the high-priority client. If there are no lower-priority clients to disassociate, the AP will reject the association request.

The command auth open-system disables encryption and 802.1X.◆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 Commands” on page 173) and RADIUS server details (see “RADIUS Client Commands” on page 167) must be configured on the access point. A RADIUS server must also be configured and be available in the wired network.◆If a WPA/WPA2 mode that operates over 802.1X is selected (WPA, WPA2, WPA-WPA2-mixed, or WPA-WPA2-PSK-mixed), the 802.1X settings (see “802.1X Authentication Commands” on page 173) and RADIUS server details (see “RADIUS Client Commands” on page 167) must be configured. Be sure you have also configured a RADIUS server on the network before enabling authentication. Also, note that each client has to be WPA-enabled or support 802.1X client software. A RADIUS server must also be configured and be available in the wired network.◆If a WPA/WPA2 Pre-shared Key mode is selected (WPA-PSK, WPA2-PSK or WPA-WPA2-PSK-mixed), the key must first be generated and distributed to all wireless clients before they can successfully associate with the access point. Use the wpa-preshared-key command to configure the key (see “key” on page 235 and “transmit-key” on page 236).
Chapter 25  |  Wireless Security Commands–  234  –◆WPA2 defines a transitional mode of operation for networks moving from WPA security to WPA2. WPA2 Mixed Mode allows both WPA and WPA2 clients to associate to a common VAP interface. When the encryption cipher suite is set to TKIP, the unicast encryption cipher (TKIP or AES-CCMP) is negotiated for each client. The access point advertises it’s supported encryption ciphers in beacon frames and probe responses. WPA and WPA2 clients select the cipher they support and return the choice in the association request to the access point. For mixed-mode operation, the cipher used for broadcast frames is always TKIP. WEP encryption is not allowed.ExampleAP(if-wireless 0: VAP[0])# auth wpa-pskAP(if-wireless 0: VAP[0])#Related Commandsencryptionkeyencryption This command enables data encryption for wireless communications. Use the no form to disable data encryption.Syntax[no] encryptionDefault Setting disabledCommand Mode Interface Configuration (Wireless-VAP)Command Usage ◆Selecting a security method using the auth command, automatically enables data encryption (WEP, TKIP, or AES-CCMP) for the VAP. Only use this command when using WEP encryption with an Open System.◆Encryption is implemented in this device to prevent unauthorized access to your wireless network. For more secure data transmissions, enable encryption by selecting a security method using the auth command, or by using the encryption command when using WEP encryption only.◆The encryption settings must be the same on each client in your wireless network.◆Note that encryption protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet.

Other keys can be used for decryption of data from clients.◆When using dynamic keys with 802.1X, the access point uses a dynamic key to encrypt unicast and broadcast messages to 802.1X-enabled clients. However, because the access point sends the keys during the 802.1X authentication process, these keys do not have to appear in the client’s key list.ExampleAP(if-wireless 0: VAP[0])# transmit-key 1This setting has not been effective !If want to take effect, please execute make-security-effective command !AP(if-wireless 0: VAP[0])#
Chapter 25  |  Wireless Security Commands–  237  –cipher-suite This command defines the cipher algorithm used to encrypt the global key for broadcast and multicast traffic when using WPA or WPA2 security. Syntaxmulticast-cipher <aes-ccmp | tkip >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. Default Setting NoneCommand Mode Interface Configuration (Wireless-VAP)Command Usage ◆WPA and WPA2 enable a VAP 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.◆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. ◆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.

Chapter 25  |  Wireless Security Commands–  239  –pmksa-lifetime This command sets the time for aging out cached WPA2 Pairwise Master Key Security Association (PMKSA) information for fast roaming.Syntaxpmksa-lifetime <minutes>minutes - The time for aging out PMKSA information. (Range: 0 - 14400 minutes)Default Setting 720 minutesCommand Mode Interface Configuration (Wireless-VAP)Command Usage ◆WPA2 provides fast roaming for authenticated clients by retaining keys and other security information in a cache, so that if a client roams away from an access point and then returns reauthentication is not required. ◆When a WPA2 client is first authenticated, it receives a Pairwise Master Key (PMK) that is used to generate other keys for unicast data encryption.

–  241  –26 Rogue AP Detection CommandsA “rogue AP” is either an access point that is not authorized to participate in the wireless network, or an access point that does not have the correct security configuration. Rogue 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 access point can be configured to periodically scan all radio channels and find other access points within range. A database of access points is maintained so that any rogue APs can be identified.rogue-ap enable This command enables the periodic detection of nearby access points.

Therefore, avoid frequent scanning or scans of a long duration unless there is a reason to believe that more intensive scanning is required to find a rogue AP.◆A “rogue AP” is either an access point that is not authorized to participate in the wireless network, or an access point that does not have the correct security configuration. Rogue access points can be identified by unknown BSSID (MAC address). A database of nearby access points should therefore be maintained on the AP, allowing any rogue APs to be identified (see rogue-ap add friendly). The rogue AP database can be viewed using the show rogue-ap command.ExampleAP(if-wireless 0)#rogue-ap enableIf want to take effect, please execute make-RF-setting-effective command !AP(if-wireless 0)# rogue-ap disable This command disables the periodic detection of nearby access points.

–  247  –27 Link Integrity CommandsThe access point provides a link integrity feature that can be used to ensure that wireless clients are connected to resources on the wired network. The access point does this by periodically sending Ping messages to a host device in the wired Ethernet network. If the access point detects that the connection to the host has failed, it disables the radio interfaces, forcing clients to find and associate with another access point. When the connection to the host is restored, the access point re-enables the radio interfaces.link-integrity This command enables link integrity detection and configures the IP address, detect interval, response timeout, and retry count for the link integrity host test. Use the no form to disable link integrity detection.Syntaxlink-integrity [<ip_address> interval <interval> timeout <timeout> retry <retry>]no link-integrityip_address - IP address of the host. interval - The interval time between each Ping sent to the host. (Range: 10-86400 seconds)timeout - The time to wait for a response to a Ping message. (Range: 1-10 seconds)retry - The number of consecutive failed Ping counts before the link is determined as lost.

–  254  –29 VLAN CommandsThe access point can enable the support of VLAN-tagged traffic passing between wireless clients and the wired network. VLAN IDs can be mapped to specific VAP interfaces, allowing users to remain within the same VLAN as they move around a campus site.Caution: When VLANs are enabled, the access point’s Ethernet port drops all received traffic that does not include a VLAN tag. To maintain network connectivity to the access point and wireless clients, be sure that the access point is connected to a device port on a wired network that supports IEEE 802.1Q VLAN tags.The VLAN commands supported by the access point are listed below.vlan This command enables VLANs for all traffic.

–  258  –30 WMM CommandsThe access point implements QoS using the Wi-Fi Multimedia (WMM) standard. Using WMM, the access point is able to prioritize traffic and optimize performance when multiple applications compete for wireless network bandwidth at the same time. WMM employs techniques that are a subset of the IEEE 802.11e QoS standard and it enables the access point to inter-operate with both WMM-enabled clients and other devices that may lack any WMM functionality.wmm This command enables WMM on the access point. Use the no form to disable WMM.Syntaxwmm requiredno wmm required - WMM must be supported on any device trying to associated with the access point.

DefaultackCommand ModeInterface Configuration (Wireless)Command Usage ◆WMM defines four access categories (ACs) – voice, video, best effort, and background. These categories correspond to traffic priority levels and are mapped to IEEE 802.1D priority tags. The direct mapping of the four ACs to 802.1D priorities is specifically intended to facilitate interpretability with other wired network QoS policies. While the four ACs are specified for specific types of traffic, WMM allows the priority levels to be configured to match any network-wide QoS policy. WMM also specifies a protocol that access points can use to communicate the configured traffic priority levels to QoS-enabled wireless clients.◆Although turning off the requirement for the sender to wait for an acknowledgement can increases data throughput, it can also result in a high number of errors when traffic levels are heavy.ExampleAP(if-wireless 0)# wmm-acknowledge-Policy 0 noAckThis setting has not been effective !If want to take effect, please execute make-RF-setting-effective command !AP(if-wireless 0)#wmmparam This command configures detailed WMM parameters that apply to the access point (AP) or the wireless clients (BSS).Syntaxwmmparam <AP | BSS> <ac_number> <LogCwMin> <LogCwMax> <AIFS> <TxOpLimit> <admission_control>

The templates also have user-defined name that can be configured using the qos qos-template qos-template-name command.◆The QoS priority mapping templates can be configured using the qos qos-template qos-template-priority command.ExampleAP(if-wireless 0: VAP[0])# qos 802.1d-802.1p mapping-template 3This setting has not been effective !If want to take effect, please execute make-security-effective command !AP(if-wireless 0: VAP[0])#qos 802.1d-dscp This command enables the mapping of WMM 802.1d priority values to IP DSCP values on a VAP interface.Syntaxqos 802.1d-dscp <enable | disable>enable - Enables the mapping of WMM 802.1d to DSCP priority values. disable - Disables the feature. DefaultDisabledCommand ModeInterface Configuration (Wireless-VAP)Command Usage ◆This QoS feature requires a QoS mapping template to be configured using the qos qos-template qos-template-priority command. The mapping template can then be linked to the 802.1d-to-DSCP priority mapping using the qos 802.1d-dscp mapping-template command.◆Both “802.1d to 802.1p” mapping and “802.1d to DSCP” mapping can be enabled simultaneously when the default VLAN ID for the VAP is any other value than 1. When only 802.1d-to-DSCP mapping is enabled, the default VLAN ID for the VAP must be set to 1.ExampleAP(if-wireless 0: VAP[0])# qos 802.1d-dscp enableThis setting has not been effective !If want to take effect, please execute make-security-effective command !

–  272  –ATroubleshootingProblems Accessing the Management Interface Using System LogsIf a fault does occur, refer to the Installation Guide to ensure that the problem you encountered is actually caused by the AP. If the problem appears to be caused by the AP, follow these steps:1. Enable logging. 2. Set the error messages reported to include all categories. 3. Enable SNMP.4. Enable SNMP traps.Table 30: Troubleshooting ChartSymptom ActionCannot connect using Telnet, web browser, or SNMP software◆Be sure the AP is powered up.◆Check network cabling between the management station and the AP.◆Check that you have a valid network connection to the AP and that intermediate switch ports have not been disabled.◆Be sure you have configured the AP with a valid IP address, subnet mask and default gateway.◆Be sure the management station has an IP address in the same subnet as the AP’s IP.◆If you are trying to connect to the AP using a tagged VLAN group, your management station, and the ports connecting intermediate switches in the network, must be configured with the appropriate tag. ◆If you cannot connect using Telnet, you may have exceeded the maximum number of concurrent Telnet/SSH sessions permitted. Try connecting again at a later time. Cannot access the CLI through a serial port connection◆Be sure you have set the terminal emulator program to VT100 compatible, 8 data bits, 1 stop bit, no parity, and the baud rate set to 115200 bps. ◆Check that the null-modem serial cable conforms to the pin-out connections provided in the Installation Guide. Forgot or lost the password ◆Reset the AP to factory defaults using its Reset button.
Appendix A  |  TroubleshootingUsing System Logs–  273  –5. Designate the SNMP host that is to receive the error messages. 6. Repeat the sequence of commands or other actions that lead up to the error. 7. Make a list of the commands or circumstances that led to the fault. Also make a list of any error messages displayed. 8. Set up your terminal emulation software so that it can capture all console output to a file. Then enter the “show config” command to record all system settings in this file.9. Contact your distributor’s service engineer, and send a detailed description of the problem, along with the file used to record your system settings. For example:AP(config)#logging onAP(config)#logging host 1 10.1.0.3AP(config)#logging level alertAP(config)#snmp-server host 1 10.1.0.23 batman...
