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 – 17 – 1 Introduction The access point (AP) runs software that includes a network management agent. The agent offers a variety of management options, including SNMP and a webbased interface. A PC may also be connected directly to the AP’s console port for configuration using a command line interface (CLI). Configuration Options The 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 – 18 – Chapter 1 | Introduction Console Port Connection Console Port Connection The 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 nullmodem 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. The “User Access Verification” procedure starts. – 19 – Chapter 1 | Introduction Network Connections 2. At the login prompt, enter “admin.” 3. At the Password prompt, press . 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: admin Password: Jan 1 11:33:13 login[1918]: root login on 'ttyS0' SMC# Network Connections Prior 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 Interface The 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. – 20 – Chapter 1 | Introduction Connecting to the Web Interface 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 Page Home Page and Main After logging in to the web interface, the home page displays. The home page Menu shows some basic settings for the AP, including Country Code and the management access password. Figure 2: The Home Page – 21 – Chapter 1 | Introduction Connecting to the Web Interface The web interface Main Menu menu provides access to all the configuration settings available for the AP. To configure settings, click the relevant Main Menu item. Each Main Menu item is sumarized below with links to the relevant section in this guide where configuration parameters are described in detail: ◆ System — Configures Management IP, WAN, LAN and QoS settings.

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 Steps First 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#configure SMC(config)#interface ethernet SMC(config-if)# First type “no ip dhcp” to disable DHCP client mode. Then type “ip address ipaddress 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 dhcp SMC(if-ethernet)#ip address 192.168.2.2 255.255.255.0 192.168.2.254 SMC(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. – 24 – Chapter 2 | Initial Configuration CLI Initial Configuration Steps 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 . Type “password admin null password,” where “null” is the default old password, and “password” is your new password. Press . Example AP#configure AP(config)#password admin null tpschris AP(config)# Setting the Country You must set the country code of the AP to be sure that the radios operate Code 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). Example AP#country ?

Click “System’” followed by “Quick Start’” Step 1 The first page of the Quick Start configures the system identification, access password, and the Country Code. – 26 – Chapter 2 | Initial Configuration Web Quick Start Figure 5: Quick Start - Step 1 The following items are displayed on the first page of the Quick Start wizard: Identification ◆ System Name — The name assigned to the access point. (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. – 27 – Chapter 2 | Initial Configuration Web Quick Start 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 2 The 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. – 28 – Chapter 2 | Initial Configuration Web Quick Start ◆ 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 3 The 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) – 29 – Chapter 2 | Initial Configuration Web Quick Start 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. AESCCMP is the standard encryption cipher required for WPA2. – 30 – Chapter 2 | Initial Configuration Web Quick Start 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 – 31 – Section II Web Configuration This section provides details on configuring the access point using the web browser interface. This section includes these chapters: ◆ “System Settings” on page 33 ◆ “Management Settings” on page 49 ◆ “Advanced Settings” on page 60 ◆ “Wireless Settings” on page 67 ◆ “Maintenance Settings” on page 91 ◆ “Status Information” on page 97 – 32 – 3 System Settings This chapter describes basic system settings on the access point.

Figure 9: Administration The following items are displayed on this page: ◆ System Name — An alias for the AP, enabling the device to be uniquely identified on the network. (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. – 34 – Chapter 3 | System Settings IPv4 Address 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 Address Configuring 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 Configuration The 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. – 35 – Chapter 3 | System Settings IPv6 Address 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. 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. If you have one or more DNS servers located on the local network, type the IP addresses in the text fields provided. ◆ 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) IPv6 Address This section describes how to configure an IPv6 interface for management access over the network. This AP supports both IPv4 and IPv6, and can be managed through either of these address types. By default, the AP will be not be automatically configured with IPv6 settings from a DHCPv6 server. The default IPv6 address is 2001:db8::1, subnet mask 64 and a default gateway of 2001:db8::2. Figure 11: IPv6 Configuration The following items are displayed on this page: – 36 – Chapter 3 | System Settings RADIUS Settings ◆ DHCP Status — Enables/disables DHCPv6 on the access point. ◆ IP Address — Specifies an IPv6 address for management of the access point. (Default: 2001:db8::1) ◆ Subnet Mask — Indicates the local subnet mask. (Default: 64) ◆ Default Gateway — The default gateway is the IPv6 address of the router for the access point, which is used if the requested destination address is not on the local subnet. If you have management stations, DNS, RADIUS, or other network servers located on another subnet, type the IPv6 address of the default gateway router in the text field provided. ◆ Primary and Secondary DNS Address — The IPv6 address of Domain Name Servers on the network. A DNS maps numerical IPv6 addresses to domain names and can be used to identify network hosts by familiar names instead of the IPv6 addresses. If you have one or more DNS servers located on the local network, type the IPv6 addresses in the text fields provided. RADIUS Settings Remote Authentication Dial-in User Service (RADIUS) is an authentication protocol that uses software running on a central server to control access to RADIUS-aware devices on the network. An authentication server contains a database of user credentials for each user that requires access to the network. Primary and A primary RADIUS server must be specified for the access point to implement IEEE Secondary RADIUS 802.1X network access control and Wi-Fi Protected Access (WPA) wireless security. Server Setup 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. – 37 – Chapter 3 | System Settings RADIUS Settings Figure 12: RADIUS Settings The 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. – 38 – Chapter 3 | System Settings System Time ◆ 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 Time Simple 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 – 39 – Chapter 3 | System Settings VLAN Configuration 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 Saving The access point provides a way to automatically adjust the system clock for Settings 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 Configuration VLANs (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. – 40 – Chapter 3 | System Settings VLAN Configuration 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 Identity The 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) – 41 – Chapter 3 | System Settings System Logs System Logs The access point can be configured to send event and error messages to a System Log Server. The system clock can also be synchronized with a time server, so that all the messages sent to the Syslog server are stamped with the correct time and date. Figure 15: System Log Settings The 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. (Default: disabled) ◆ IP — The IP address or name of a Syslog server. (Server 1 Default: 10.7.16.98; Server 2 Default: 10.7.13.48; Server 3 Default: 10.7.123.123; Server 4 Default: 10.7.13.77) ◆ UDP Port — The UDP port used by a Syslog server. (Range: 514 or 1102465535; Server 1~2 Default: 514; Server 3 Default: 6553; Server 4 Default: 5432) ◆ Logging Console — Enables the logging of error messages to the console. (Default: disabled) – 42 – Chapter 3 | System Settings Quick Start Wizard ◆ Logging Level — Sets the minimum severity level for event logging. (Default: Debug) The system allows you to limit the messages that are logged by specifying a minimum severity level. The following table lists the error message levels from the most severe (Emergency) to least severe (Debug). The message levels that are logged include the specified minimum level up to the Emergency level. Table 1: Logging Levels Error Level Description Emergency System unusable Alerts Immediate action needed Critical Critical conditions (e.g., memory allocation, or free memory error resource exhausted) Error Error conditions (e.g., invalid input, default used) Warning Warning conditions (e.g., return false, unexpected return) Notice Normal but significant condition, such as cold start Informational Informational messages only Debug Debugging messages Quick Start Wizard The Quick Start menu item is described in the preceding chapter, see “Web Quick Start” on page 26. – 43 – Chapter 3 | System Settings System Resource System Resource The System Resource page displays information on the AP’s current CPU and memory utilization. This page also allows you to set thresholds for the CPU and memory usage, where an SNMP trap can be sent as an alert. Figure 16: System Resource The following items are displayed on this page: ◆ CPU Rising Threshold — A high CPU utilization percentage above which a “CPU Busy” SNMP trap message is sent (only sent once). (Range: 1-100 percent, 0 is disabled; Default: 0) ◆ CPU Falling Threshold — A low CPU utilization percentage below which a “CPU Free” SNMP trap message is sent once the Rising Threshold has been exceeded. (Range: 0 to less than the Rising Threshold; Default: 20) ◆ Memory Rising Threshold — A high memory utilization threshold in Kbytes above which a “Memory Overload” SNMP trap message is sent (only sent once). (Range: 1-113076 Kbytes, 0 is disabled; Default: 0) ◆ Memory Falling Threshold — A low memory utilization threshold in Kbytes below which a “Memory Free” SNMP trap message is sent once the Rising Threshold has been exceeded. (Range: 0 to less than the Rising Threshold; Default: 16000 Kbytes) ◆ Threshold Interval — The interval in seconds between each CPU utilization check. (Range: 1 to 86400 seconds, 0 is disabled; Default: 0) ◆ CPU Status — Displays detailed information on the current CPU utilization. – 44 – Chapter 3 | System Settings Bridge STP Configuration ◆ Memory Status — Displays detailed information on the current memory utilization. Bridge STP Configuration The Bridge menu enables configuration of the Spanning Tree Protocol (STP) and the address table aging time. Spanning Tree The Spanning Tree Protocol (STP) can be used to detect and disable network loops, Protocol (STP) 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. – 45 – Chapter 3 | System Settings Bridge STP Configuration Figure 17: Spanning Tree Protocol Bridge Sets 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 – 46 – Chapter 3 | System Settings Bridge STP Configuration to the network. (Default: 20 seconds; Range: 6-40 seconds) Minimum: The higher of 6 or [2 x (Hello Time + 1)]. Maximum: The lower of 40 or [2 x (Forward Delay - 1)] ◆ Hello Time — Interval (in seconds) at which the root device transmits a configuration message. (Default: 2 seconds; Range: 1-10 seconds) Minimum: 1 Maximum: 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: 30 Ethernet Interface Sets 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. (Default: 32; Range: 0-63) Wireless Interface Sets STP settings for the radio interface. ◆ Index — Describes the VAP in question. ◆ 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: 19; Range: 1-65535.) – 47 – Chapter 3 | System Settings Bridge STP Configuration ◆ 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. (Default: 32; Range: 0-63) Bridge Configuration Use the Bridge Configuration page to configure the aging time for the MAC address table. The AP stores the MAC addresses for all known devices. All the addresses learned by monitoring traffic are stored in a dynamic address table. This information is used to pass traffic directly between inbound and outbound interfaces. Figure 18: Bridge Configuration The following items are displayed on the STP page: ◆ mac aging time — The time after which a learned MAC address is discarded. (Range: 10-1000000 seconds; Default: 300 seconds) – 48 – 4 Management Settings This 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 52 Remote Management Settings The Web, Telnet, and SNMP management interfaces are enabled and open to all IP addresses by default. To provide more security for management access to the access point, specific interfaces can be disabled and management restricted to a single IP address or a limited range of IP addresses. Once you specify an IP address or range of addresses, access to management interfaces is restricted to the specified addresses. 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. – 49 – Chapter 4 | Management Settings Remote Management Settings ◆ The client and server generate session keys for encrypting and decrypting data. ◆ The client and server establish a secure encrypted connection. ◆ A padlock icon should appear in the status bar for Internet Explorer.

(Default: 80; Range 1024-65535) ◆ HTTPS Server — Enables/disables management access from a HTTPS server. (Default: enabled) ◆ HTTPS Port — Specifies the HTTPS port for secure IP connectivity. (Default: 443; Range 1024-65535) ◆ SNMP Access — Enables management access through SNMP. For more information on SNMP access, see “Simple Network Management Protocol” on page 52. (Default: enabled) Access Limitation The Access Limitation page limits management access to the access point from specified IP addresses or wireless clients. Figure 20: Access Limitation The following items are displayed on the Access Limitation page: IP Management Control ◆ Any IP — Indicates that any IP address is allowed management access. ◆ Single IP — Specifies a single IP address that is allowed management access. ◆ Multiple IP — Specifies an address range as defined by the entered IP address and subnet mask. For example, IP address 192.168.1.6 and subnet mask 255.255.255.0, defines all IP addresses from 192.168.1.1 to 192.168.1.254. – 51 – Chapter 4 | Management Settings Simple Network Management Protocol ◆ IP Address — Specifies the IP address. ◆ Subnet Mask — Specifies the subnet mask in the form 255.255.255.x Restrict Management ◆ Enable/Disable — Enables/disables management of the device by a wireless client. (Default: disabled) DHCP Filter ◆ Enable/Disable — Enables/disables the AP and wireless clients from obtaining an IP address from a DHCP server installed on wireless client. (Default: disabled) Simple Network Management Protocol Simple 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 – 52 – Chapter 4 | Management Settings Simple Network Management Protocol strings to be configured for authentication. Trap notifications can be enabled and sent to up to four management stations. Figure 21: SNMP Basic Settings The 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. Authorized management stations are able to both retrieve and modify MIB objects. (Maximum length: 23 characters, case sensitive; Default: private) – 53 – Chapter 4 | Management Settings Simple Network Management Protocol SNMP Trap Settings Traps indicating status changes are issued by the AP to specified trap managers. You must specify trap managers so that key events are reported by the AP to your management station (using network management platforms). Figure 22: SNMP Trap Settings The following items are displayed on this page: ◆ Trap Destination — Specifies the recipient of SNMP notifications. Enter the IP address or the host name. (Host Name: 1 to 63 characters, case sensitive) ◆ Community — The community string sent with the notification operation. (Maximum length: 23 characters, case sensitive; Default: public) ◆ Action — Adds a new SNMP trap destination to the list. ◆ Trap Destination List — Lists the configured SNMP trap destinations. ◆ Trap Configuration — Enables or disables trap status. ◆ ■ sysSystemUp: The access point is up and running. ■ sysSystemDown: The access point is about to shutdown and reboot. Save Trap Config — Applies the new parameters and saves them to RAM memory. Also prompts a screen to inform you when it has taken affect. Clicking ‘OK’ returns to the home page. Changes will not be saved upon a reboot unless the running configuration file is saved. – 54 – Chapter 4 | Management Settings Simple Network Management Protocol View Access Control To configure SNMPv3 management access to the AP, follow these steps: Model 1. Specify read and write access views for the AP MIB tree. 2. Configure SNMP user groups with the required security model (that is, SNMP v1, v2c, or v3) and security level (authentication and privacy). 3. Assign SNMP users to groups, along with their specific authentication and privacy passwords. Figure 23: SNMP VACM Creating Views SNMPv3 views are used to restrict user access to specified portions of the MIB tree. The are no predefined views by default. The following items are displayed on the VACM page. ◆ View Name – The name of the SNMP view. (Range: 1-32 characters) ◆ Type – Indicates if the object identifier of a branch within the MIB tree is included or excluded from the SNMP view. ◆ OID – Allows you to configure the object identifiers of branches within the MIB tree. Wild cards can be used to mask a specific portion of the OID string. ◆ Mask (option) – A hexadecimal value with each bit masking the corresponding ID in the MIB subtree. A “1” in the mask indicates an exact match and a “0” indicates a “wild card.” For example, a mask value of 0xFFBF provides a bit mask – 55 – Chapter 4 | Management Settings Simple Network Management Protocol “1111 1111 1011 1111.” If applied to the subtree “1.3.6.1.2.1.2.2.1.1.23,” the zero corresponds to the 10th subtree ID. When there are more subtree IDs than bits in the mask, the mask is padded with ones. ◆ View List – Shows the currently configured object identifiers of branches within the MIB tree that define the SNMP view. Creating Groups An 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 – 56 – Chapter 4 | Management Settings Simple Network Management Protocol 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 readonly (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.) – 57 – Chapter 4 | Management Settings Simple Network Management Protocol Figure 25: SNMPv3 Targets The following items are displayed on this page: ◆ Target ID — A user-defined name that identifies a receiver of notifications. (Maximum length: 32 characters) ◆ IP Address — Specifies the IP address of the receiving management station. ◆ UDP Port — The UDP port that is used on the receiving management station for notification messages. ◆ SNMP User — The defined SNMP v3 user that is to receive notification messages. ◆ Notification Filter — The name of a user-defined notification filter that is applied to the target. SNMPv3 Notification SNMP v3 users can be configured to receive notification messages from the access Filters point. An SNMP Target ID is created that specifies the SNMP v3 user, IP address, and UDP port. A user-defined notification filter can be created so that specific notifications can be prevented from being sent to particular targets. Figure 26: SNMP Notification Filter – 58 – Chapter 4 | Management Settings Simple Network Management Protocol The following items are displayed on this page: ◆ Filter ID — A user-defined name that identifies the filter. (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. – 59 – 5 Advanced Settings This chapter describes advanced settings on the access point. 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 66 Local Bridge Filter The access point can employ network traffic frame filtering to control access to network resources and increase security. You can prevent communications between wireless clients and prevent access point management from wireless clients. Also, you can block specific Ethernet traffic from being forwarded by the access point. 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 Filter The following items are displayed on this page: ◆ Disabled — All clients can communicate with each other through the access point. – 60 – Chapter 5 | Advanced Settings Link Layer Discovery Protocol ◆ 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 Protocol This 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 Settings The 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) – 61 – Chapter 5 | Advanced Settings Link Layer Discovery Protocol 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 – 62 – Chapter 5 | Advanced Settings Access Control Lists Access Control Lists Access 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 Address The ACL Source Address Settings page enables traffic filtering based on the source Settings MAC address in the data frame. Figure 29: Source ACLs The 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. – 63 – Chapter 5 | Advanced Settings Access Control Lists Destination Address The ACL Destination Address Settings page enables traffic filtering based on the Settings destination MAC address in the data frame. Figure 30: Destination ACLs The following items are displayed on this page: ◆ DA Status — Enables network traffic with specific destination MAC addresses to be filtered (dropped) from the access point. ◆ MAC Address — Specifies a destination 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 deletes the specified MAC address. ◆ Number — Specifies the number of the MAC address in the filter table. ◆ MAC Address — Displays the configured destination MAC address. – 64 – Chapter 5 | Advanced Settings Access Control Lists Ethernet Type The Ethernet Type Filter controls checks on the Ethernet type of all incoming and outgoing Ethernet packets against the protocol filtering table. (Default: Disabled) Figure 31: Ethernet Type Filter The 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. – 65 – Chapter 5 | Advanced Settings Link Integrity Link Integrity The 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 Integrity The 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) – 66 – 6 Wireless Settings This chapter describes wireless settings on the access point. It includes the following sections: ◆ “Authentication” on page 68 ◆ “Radio Settings” on page 71 ◆ “Virtual Access Points (VAPs)” on page 75 ◆ “Rogue AP Detection” on page 84 ◆ “Wi-Fi Multimedia (WMM)” on page 86 – 67 – Chapter 6 | Wireless Settings Authentication Authentication Wireless clients can be authenticated for network access by checking their MAC address against the local database configured on the access point, or by using a database configured on a central RADIUS server. Alternatively, authentication can be implemented using the IEEE 802.1X network access control protocol. 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 MAC Configures the local MAC authentication database. The MAC database provides a Authentication 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 Authentication The following items are displayed on Authentication page: MAC Authentication — Selects between, disabled, Local MAC authentication and RADIUS authentication. – 68 – Chapter 6 | Wireless Settings Authentication ◆ 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 MAC The MAC address of the associating station is sent to a configured RADIUS server for Authentication authentication. When using a RADIUS authentication server for MAC address authentication, the server must first be configured on the RADIUS page. Figure 34: RADIUS Authentication The following items are displayed on Authentication page: MAC Authentication — Selects between, disabled, Local MAC authentication and RADIUS authentication. – 69 – Chapter 6 | Wireless Settings Authentication ◆ 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) – 70 – Chapter 6 | Wireless Settings Radio Settings Radio Settings The 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 interface Each 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 – 71 – Chapter 6 | Wireless Settings Radio Settings 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. – 72 – Chapter 6 | Wireless Settings Radio Settings 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 – 73 – Chapter 6 | Wireless Settings Radio Settings 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: MCS0MCS7; 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: MCS8MCS15; 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. – 74 – Chapter 6 | Wireless Settings Virtual Access Points (VAPs) 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 Settings The 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) – 75 – Chapter 6 | Wireless Settings Virtual Access Points (VAPs) ◆ 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 Settings The 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) – 76 – Chapter 6 | Wireless Settings Virtual Access Points (VAPs) ◆ 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 highpriority 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. – 77 – Chapter 6 | Wireless Settings Virtual Access Points (VAPs) ◆ 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 Mode The 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 Security Describes the wireless security settings for each VAP, including association mode, Settings 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 – 78 – Chapter 6 | Wireless Settings Virtual Access Points (VAPs) 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. AESCCMP is the standard encryption cipher required for WPA2. – 79 – Chapter 6 | Wireless Settings Virtual Access Points (VAPs) ◆ 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 Equivalent WEP provides a basic level of security, preventing unauthorized access to the Privacy (WEP) 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. – 80 – Chapter 6 | Wireless Settings Virtual Access Points (VAPs) Figure 40: WEP Configuration The following items are on this page for WEP configuration: ◆ Default WEP Key Index – Selects the key number to use for encryption for the VAP interface. If the clients have all four WEP keys configured to the same values, you can change the encryption key to any of the settings without having to update the client keys. (Default: Key 1) ◆ Key Type – Select the preferred method of entering WEP encryption keys for the VAP, either hexadecimal digits (Hex) or alphanumeric characters (ASCII). ◆ Key Length – Select 64 Bit or 128 Bit key length. Note that the same size of encryption key must be supported on all wireless clients. (Default: 64 bit) ◆ Key – Enter up to four WEP encryption keys for the VAP. ■ Hex: Enter keys as 10 hexadecimal digits (0-9 and A-F) for 64 bit keys, or 26 hexadecimal digits for 128 bit keys. ■ ASCII: Enter keys as 5 alphanumeric characters for 64 bit keys, or 13 alphanumeric characters for 128 bit keys. Note: Key index, type, and length must match that configured on the clients. – 81 – Chapter 6 | Wireless Settings Virtual Access Points (VAPs) VAP QoS Settings Click the QoS Setting link from the VAP Settings page to access the QoS priority mapping configuration for traffic on the VAP interface. Figure 41: QoS Settings The following items are displayed in the VAP QoS Settings page: ◆ VAP to 802.1p Setting — You can modify the VLAN priority tags of traffic on the VAP interface with a specified priority value. Requires the default VLAN ID for the VAP to be any other value than 1. Note: The VAP-to-802.1p priority QoS feature cannot be enabled together with the 802.1d-to-802.1p or 802.1d-to-DSCP features. ◆ 802.1d to 802.1p Setting — Enables the mapping of traffic priority from WMM 802.1d priorities to 802.1p VLAN tag priority values. The priorities are mapped according to the user-defined QoS Template map. Requires the default VLAN ID for the VAP to be any other value than 1. ◆ 802.1d to DSCP Setting — Enables the mapping of traffic priority from WMM 802.1d priorities to IP DSCP priority values. The priorities are mapped according to the user-defined QoS Template map. – 82 – Chapter 6 | Wireless Settings Virtual Access Points (VAPs) 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. ◆ QoS Template — Enables up to eight user-defined priority mapping tables to be configued. The tables are used to map the WMM 802.1d priorities to 802.1p/ DSCP priorities. Click the “Edit” link in the list to define a template priority map. Figure 42: QoS Template Setting The following items are displayed in the QoS Template Setting page: ◆ QoS Template Name — A descriptive name that identifies the mappng template. All eight templates have a default name that can be edited by the user (maximum 32 characters). ◆ Vap/802.1d (Default User Priority) — The WMM 802.1d priority value in a tagged packet. ◆ 802.1p/DSCP (Retagged User Priority) — The 802.1p or IP DSCP priority value that replaces the WMM 802.1d value in tagged packets. (Range: 0-7) – 83 – Chapter 6 | Wireless Settings Rogue AP Detection VAP Bandwidth Click the Bandwidth Setting link from the VAP Settings page to configure rate Settings limiting for traffic on the VAP interface. Figure 43: Bandwidth Settings The following items are displayed on this page: ◆ Bandwidth Control on Uplink Setting — Enables the rate limiting of traffic from the VAP interface as it is passed to the wired network. You can set a maximum rate in kbytes per second. (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 Detection 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 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). – 84 – Chapter 6 | Wireless Settings Rogue AP Detection Figure 44: Rogue AP Detection The 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. – 85 – Chapter 6 | Wireless Settings Wi-Fi Multimedia (WMM) ◆ 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. – 86 – Chapter 6 | Wireless Settings Wi-Fi Multimedia (WMM) Table 2: WMM Access Categories Access Category WMM Designation Description 802.1D Tags AC_VO (AC3) Voice Highest priority, minimum delay. Time-sensitive data such as VoIP (Voice over IP) calls. 7, 6 AC_VI (AC2) Video High priority, minimum delay. Time-sensitive data such as streaming video. 5, 4 AC_BE (AC0) Best Effort Normal priority, medium delay and throughput. Data only affected by long delays. Data from applications or devices that lack QoS capabilities. 0, 3 AC_BK (AC1) Background Lowest priority. Data with no delay or throughput requirements, such as bulk data transfers. 2, 1 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 time After 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. – 87 – Chapter 6 | Wireless Settings Wi-Fi Multimedia (WMM) Figure 45: WMM Backoff Wait Times Time CWMin High Priority CWMax AIFS Random Backoff Minimum Wait Time Random Wait Time CWMin Low Priority CWMax AIFS Random Backoff Minimum Wait Time Random Wait Time For 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: QoS – 88 – Chapter 6 | Wireless Settings Wi-Fi Multimedia (WMM) The following items are displayed on this page: ◆ ◆ WMM — Sets the WMM operational mode on the access point. 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. (Default: Acknowledge) ■ Aknowledge — Applies the WMM policy. ■ No Aknowledge — Ignores the WMM policy. ◆ WMM BSS Parameters — These parameters apply to the wireless clients. ◆ WMM AP Parameters — These parameters apply to the access point. ■ logCWMin (Minimum Contention Window): The initial upper limit of the random backoff wait time before wireless medium access can be attempted. The initial wait time is a random value between zero and the 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 datarate traffic. Specify a value in the range 0-65535 microseconds. – 89 – Chapter 6 | Wireless Settings Wi-Fi Multimedia (WMM) ■ ◆ Admission Control: The admission control mode for the access category.

Using the access point’s command-line interface (CLI) is very similar to entering commands on a UNIX system. Console Connection To 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: admin Password: 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. – 109 – Chapter 9 | Using the Command Line Interface Telnet Connection Telnet Connection Telnet 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#configure AP(config)#interface ethernet AP(if-ethernet)#ip address 10.1.0.1 255.255.255.0 10.1.0.254 AP(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: admin Password: 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. – 110 – Chapter 9 | Using the Command Line Interface Entering Commands Entering Commands This section describes how to enter CLI commands. Keywords and A CLI command is a series of keywords and arguments. Keywords identify a Arguments 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 tpschris Minimum The CLI will accept a minimum number of characters that uniquely identify a Abbreviation command. For example, the command “configure” can be entered as con. If an entry is ambiguous, the system will prompt for further input. Command If you terminate input with a Tab key, the CLI will print the remaining characters of a Completion partial keyword up to the point of ambiguity. In the “configure” example, typing con followed by a tab will result in printing the command up to “configure.” Getting Help on You can display a brief description of the help system by entering the help Commands 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 authentication bridge config event-log filters firmware-image Show Show Show Show Show Show Show management AP information. Authentication parameters. bridge. current configuration. event log on console. filters. firmware images version. – 111 – Chapter 9 | Using the Command Line Interface Entering Commands interface line lldp logging long-distance radius rogue-ap snmp sntp station system version wds AP: show Show interface information.

The command “show interface ?” will display the following information: AP# show interface ? ethernet Show Ethernet interface wireless Show Wireless interface AP# show interface Negating the Effect of For many configuration commands you can enter the prefix keyword “no” to cancel Commands the effect of a command or reset the configuration to the default value. For example, the logging command will log system messages to a host server. To disable logging, specify the no logging command. This guide describes the negation effect for all applicable commands. Using Command The CLI maintains a history of commands that have been entered. You can scroll History 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. Understanding The command set is divided into Exec and Configuration classes. Exec commands Command Modes 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 – 112 – Chapter 9 | Using the Command Line Interface Entering Commands current mode. The command classes and associated modes are displayed in the following table: Table 3: Command Modes Class Mode Exec Privileged Configuration Global Interface-ethernet Interface-wireless Interface-wireless-vap Exec Commands When you open a new console session on an access point, the system enters Exec command mode. Only a limited number of the commands are available in this mode. You can access all other commands only from the configuration mode. To access Exec mode, open a new console session with the user name “admin.” The command prompt displays as “AP#” for Exec mode. (none) login: admin Password: [system login password] AP# Configuration Commands Configuration 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. – 113 – Chapter 9 | Using the Command Line Interface Entering Commands AP#configure AP(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 ethernet AP(if-ethernet)# Command Line Commands are not case sensitive. You can abbreviate commands and parameters Processing 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. – 114 – 10 General Commands This chapter details general commands that apply to the CLI.

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. Table 10: DHCP Relay Commands Command Function Mode Page dhcp-relay server Sets the DHCP server address and enables the DHCP relay agent IC-WVAP 149 dhcp-relay server This command configures the DHCP server address and enables the DHCP relay agent.

Syntax bridge stp br-conf forwarding-delay seconds - Time in seconds. (Range: 4 - 30 seconds) The minimum value is the higher of 4 or [(max-age / 2) + 1]. Default Setting 15 seconds Command Mode Global Configuration Command Usage This command sets the maximum time (in seconds) the root device will wait before changing states (i.e., discarding to learning to forwarding). This delay is required because every device must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to the discarding state; otherwise, temporary data loops might result. Example AP(config)#bridge stp br-conf forwarding-delay 20 AP(config)# – 186 – Chapter 21 | Spanning Tree Commands bridge stp br-conf Use this command to configure the spanning tree bridge hello time globally for the hello-time wireless bridge.
