Chapter 1: Introduction The Dual-band Outdoor Access Point / Bridge system consists of two models that provide point-to-point or point-to-multipoint bridge links between remote Ethernet LANs, and wireless access point services for clients in the local LAN area: • SMC2891W-AG – Includes an integrated high-gain antenna for the 802.
1 Introduction Package Checklist The Dual-band Outdoor Access Point / Bridge package includes: • • • • • • One Wireless Dual-band Access Point (SMC2890W-AG or SMC2891W-AG) One Category 5e network PoE cable, length 98 ft (30 m) One power injector module and power cord 5.9 ft (1.8 m) One RS232 console cable 5.9ft (1.8 m) Outdoor pole- and wall-mounting bracket kit User Guide CD Inform your dealer if there are any incorrect, missing or damaged parts.
1 LED Indicators Top View (SMC2890W-AG) N-Type External Antenna Connector (2.4 GHz) Right Antenna N-Type External Antenna Connector (5 GHz) Right Antenna N-Type External Antenna Connector (5 GHz) Left Antenna N-Type External Antenna Connector (2.4 GHz) Left Antenna LED Indicators The access point includes eight status LED indicators, as indicated in the following figure. 802.11b/g Wireless Link/Activity 11b/g Power 11a Link Power Ethernet Link/Activity 802.
1 Introduction The 11a and 11b/g LEDs operate in two display modes, which are configurable through the management interface. The RSSI mode is for aligning antennas in a bridge link. The AP mode is for indicating data traffic rates. The following table describes the wireless status LEDs in AP mode. LED Status Description 11a (three LEDs) Off No signal detected or the 802.11a radio is disabled. 11b/g (three LEDs) Slow Flashing Green The 802.11a radio is enabled with a low level of network activity.
1 Introduction Ethernet Port The wireless bridge has one 10BASE-T/100BASE-TX 8-pin DIN port that connects to the power injector module using the included Ethernet cable. The Ethernet port connection provides power to the wireless bridge as well as a data link to the local network. The wireless bridge appears as an Ethernet node and performs a bridging function by moving packets from the wired LAN to the remote end of the wireless bridge link.
1 Grounding Point The power injector module automatically adjusts to any AC voltage between 100-240 volts at 50 or 60 Hz. No voltage range settings are required. Warning: The power injector module is designed for indoor use only. Never mount the power injector outside with the wireless bridge unit. Grounding Point Even though the wireless bridge includes its own built-in lightning protection, it is important that the unit is properly connected to ground.
1 Introduction System Configuration At each location where a unit is installed, it must be connected to the local network using the power injector module. The following figure illustrates the system component connections. External Antenna Indoor Outdoor RF Coaxial Cable Wireless Bridge Unit LAN Switch Ethernet Cable Ethernet Cable Power Injector AC Power Lightning Arrestor Ground Wire Features and Benefits • SMC2891W-AG units support a 5 GHz point-to-point wireless link up 15.
Chapter 2: Network Configuration The Dual-band Outdoor Access Point / Bridge system provides access point and bridging services through either the 5 GHz or 2.4 GHz radio interfaces. The wireless bridge units can be used just as normal 802.11a/b/g access points connected to a local wired LAN, providing connectivity and roaming services for wireless clients in an outdoor area. Units can also be used purely as bridges connecting remote LANs.
2 Network Configuration Infrastructure Wireless LAN The access point function of the wireless bridge provides access to a wired LAN for 802.11a/b/g wireless workstations. An integrated wired/wireless LAN is called an Infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless PC users and an access point that is directly connected to the wired LAN.
2 Access Point Topologies Infrastructure Wireless LAN for Roaming Wireless PCs The Basic Service Set (BSS) defines the communications domain for each access point and its associated wireless clients. The BSS ID is a 48-bit binary number based on the access point’s wireless MAC address, and is set automatically and transparently as clients associate with the access point. The BSS ID is used in frames sent between the access point and its clients to identify traffic in the service area.
2 Network Configuration Bridge Link Topologies The IEEE 802.11 standard defines a WIreless Distribution System (WDS) for bridge connections between BSS areas (access points). The outdoor wireless bridge uses WDS to forward traffic on links between units. Up to 5 WDS links can be specified for a SMC2890W-AG unit, which acts as the “Master” in the wireless bridge network. Other SMC2891W-AG units support only one WDS link, which must be to the network’s master unit.
2 Bridge Link Topologies Point-to-Multipoint Configuration A SMC2890W-AG wireless bridge can use an omnidirectional or sector antenna to connect to as many as 6 bridges in a point-to-multipoint configuration. There can only be one “Master” unit in the wireless bridge network, all other bridges must be “Slave” units. Using the 5 GHz 8 dBi omnidirectional external antenna, the SMC2890W-AG can connect to SMC2891W-AG units up to 3.3 km (2 miles) away. Using the 13.

Chapter 3: Bridge Link Planning The Dual-band Outdoor Access Point / Bridge supports fixed point-to-point or point-to-multipoint wireless links. A single link between two points can be used to connect a remote site to larger core network. Multiple bridge links can provide a way to connect widespread Ethernet LANs. For each link in a wireless bridge network to be reliable and provide optimum performance, some careful site planning is required.
3 Bridge Link Planning Visual Line of Sight Radio Line of Sight If there are obstacles in the radio path, there may still be a radio link but the quality and strength of the signal will be affected. Calculating the maximum clearance from objects on a path is important as it directly affects the decision on antenna placement and height. It is especially critical for long-distance links, where the radio signal could easily be lost.
Radio Path Planning 3 . Total Link Distance Max Clearance for 60% of First Fresnel Zone at 5.8 GHz Approximate Clearance for Earth Curvature Total Clearance Required at Mid-point of Link 0.25 mile (402 m) 4.5 ft (1.4 m) 0 4.5 ft (1.4 m) 0.5 mile (805 m) 6.4 ft (1.95 m) 0 6.4 ft (1.95 m) 1 mile (1.6 km) 9 ft (2.7 m) 0 9 ft (2.7 m) 2 miles (3.2 km) 12.7 ft (3.9 m) 0 12.7 ft (3.9 m) 3 miles (4.8 km) 15.6 ft (4.8 m) 1.8 ft (0.5 m) 17.4 ft (5.3 m) 4 miles (6.4 km) 18 ft (5.5 m) 3.
3 Bridge Link Planning (7.5 ft) mast or pole must be contructed on its roof to achieve the required antenna height. Building B is only three stories high, or 9 m (30 ft), but is located at an elevation that is 12 m (39 ft) higher than bulding A. To mount an anntena at the required height on building B, a mast or pole of only 1.3 m (4.3 ft) is needed. Warning: Never construct a radio mast, pole, or tower near overhead power lines.
Ethernet Cabling 3 Radio Interference The avoidance of radio interference is an important part of wireless link planning. Interference is caused by other radio transmissions using the same or an adjacent channel frequency. You should first scan your proposed site using a spectrum analyzer to determine if there are any strong radio signals using the 802.11a channel frequencies. Always use a channel frequency that is furthest away from another signal.
3 Bridge Link Planning • Determine if conduits, bracing, or other structures are required for safety or protection of the cable • For lightning protection at the power injector end of the cable, consider using a lightning arrestor immediately before the cable enters the building Grounding It is important that the wireless bridge, cables, and any supporting structures are properly grounded. The wireless bridge unit includes a grounding screw for attaching a ground wire.
Chapter 4: Hardware Installation Before mounting antennas to set up your wireless bridge links, be sure you have selected appropriate locations for each antenna. Follow the guidance and information in Chapter 2, “Wireless Link Planning.” Also, before mounting units in their intended locations, you should first perform initial configuration and test the basic operation of the wireless bridge links in a controlled environment over a very short range.
4 Hardware Installation The bridge’s mounting bracket has four parts. One rectangular plate that is used for pole and wall mounting, one square plate that attaches directly to the bridge, and two plates that form an adjustable V-shaped clamp for pole mounting. Mounting on a Pole Perform the following steps to mount the unit to a 1.5 to 2 inch diameter steel pole or tube using the mounting bracket: 1. Fit the edges of the V-shaped clamp parts into the slots on the flat side of the rectangular plate.
4 Mount the Unit Attach the adjustable rectangular plate to the bridge with supplied screws 4. Attach the bridge with its mounting plate to the bracket already fixed to the pole. Attach the bridge to the plate on the pole 5. Use the included nuts to secure the wireless bridge to the pole bracket. Note that the wireless bridge tilt angle may need to be adjusted during the antenna alignment process.
4 Hardware Installation Be sure to take account of the antenna polarization direction; all antennas in a link must be mounted with the same polarization. Mounting to a Wall Perform the following steps to mount the unit to a wall using the wall-mounting bracket: Note: The wall-mounting bracket does not allow the wireless bridge’s intrgrated antenna to be aligned. It is intended for use with the unit using external antennas. 1.
4 Connect External Antennas Connect External Antennas When deploying a SMC2891W-AG unit for a bridge link or access point operation, you need to mount external antennas and connect them to the bridge. Typically, a bridge link requires a 5 GHz antenna, and access point operation a 2.4 GHz antenna. SMC2890W-AG units also require an external antenna for 2.4 GHz operation. Perform these steps: 1.
4 Hardware Installation 2.4 GHz N-type Connector 5 GHz N-type Connector 5 GHz External High-gain Panel Antenna 2.4 GHz External Omnidirectional Antenna RF Coaxial Cable Connect Cables to the Unit Warning: Do not connect or disconnect cables or otherwise work with the bridge during periods of lightning activity. 1. Attach the Ethernet cable to the Ethernet port on the wireless bridge. 2.
4 Connect the Power Injector Console Port PoE (Ethernet) Port Ground Wire Grounding Screw Ethernet Cable Connect the Power Injector To connect the wireless bridge to a power source: Caution: Do not install the power injector outdoors. The unit is for indoor installation only. Caution: Install lightning protection at the power injector end of the Ethernet cable, use a lightning arrestor immediately before the cable enters the building.
4 Hardware Installation AC power Ethernet cable from LAN switch Inp ut Ou tpu t Power LED indicator Ethernet cable to wireless bridge 1. Insert the power cable plug directly into the standard AC receptacle on the power injector. 2. Plug the other end of the power cable into a grounded, 3-pin socket, AC power source. Note: For International use, you may need to change the AC line cord. You must use a line cord set that has been approved for the receptacle type in your country. 3.
4 Align Antennas The signal strength LEDs indicate the received radio signal strength for a particular bridge link. The more LEDs that turn on, the stronger the signal. Alternatively, you can monitor the Receive Signal Strength Indicator (RSSI) value directly from the management interface. The higher the RSSI value, the stronger the signal. When you move the antenna during alignment, the radio signal from the remote antenna can be seen to have a strong central main lobe and smaller side lobes.
4 Hardware Installation 1. Pan the antenna horizontally back and forth while checking the LEDs. If using the pole-mounting bracket with the unit, you must rotate the mounting bracket around the pole. Other external antenna brackets may require a different horizontal adjustment. 2. Find the point where the signal is strongest (all LEDs on) and secure the horizontal adjustment in that position.
Chapter 5: Initial Configuration The Dual-band Outdoor Access Point / Bridge offers a variety of management options, including a web-based interface, a direct connection to the console port, Telnet, Secure Shell (SSH), or using SNMP software. The initial configuration steps can be made through the web browser interface or CLI. The access point requests an IP address via DHCP by default. If no response is received from the DHCP server, then the access point uses the default address 192.168.2.2.
5 Initial Configuration For a description of how to use the CLI, see “Using the Command Line Interface” on page 7-1. For a list of all the CLI commands and detailed information on using the CLI, refer to “Command Groups” on page 7-6. Initial Configuration Steps Logging In – Enter “admin” for the user name. The default password is null, so just press [Enter] at the password prompt. The CLI prompt appears displaying the access point’s name.
5 Logging In Setting the Country Code – Units sold in the United States are configured by default to use only radio channels 1-11 in 802.11b or 802.11g mode as defined by FCC regulations. Units sold in other countries are configured by default without a country code (i.e., 99). You must use the CLI to set the country code. 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.
5 Initial Configuration The home page displays the Main Menu.
Chapter 6: System Configuration Before continuing with advanced configuration, first complete the initial configuration steps described in Chapter 4 to set up an IP address for the access point. The access point can be managed by any computer using a web browser (Internet Explorer 5.0 or above, or Netscape 6.2 or above). Enter the configured IP address of the access point, or use the default address: http://192.168.2.2 To log into the access point, enter the default user name “admin” and then press “LOGIN”.
6 System Configuration Advanced Configuration The Advanced Configuration pages include the following options. Table 6-1.
Advanced Configuration 6 Table 6-1. Menu Menu Description Radio Interface G Page Configures the IEEE 802.
6 System Configuration CLI Commands for System Identification – Enter the global configuration mode, and use the system name command to specify a new system name. Then return to the Exec mode, and use the show system command to display the changes to the system identification settings. SMC AP#config Enter configuration commands, one per line.
6 Advanced Configuration TCP / IP Settings Configuring the access point with an IP address expands your ability to manage the access point. A number of access point features depend on IP addressing to operate. Note: You can use the web browser interface to access IP addressing only if the access point already has an IP address that is reachable through your network. By default, the access point will be automatically configured with IP settings from a Dynamic Host Configuration Protocol (DHCP) server.
6 System Configuration • Default Gateway: The default gateway is the IP address of the router for the access point, which is used if the requested destination address is not on the local subnet. If you have management stations, DNS, RADIUS, or other network servers located on another subnet, type the IP address of the default gateway router in the text field provided. Otherwise, leave the address as all zeros (0.0.0.0).
6 Advanced Configuration RADIUS Remote Authentication Dial-in User Service (RADIUS) is an authentication protocol that uses software running on a central server to control access to RADIUS-aware devices on the network. An authentication server contains a database of user credentials for each user that requires access to the network. A primary RADIUS server must be specified for the access point to implement IEEE 802.1X network access control and Wi-Fi Protected Access (WPA) wireless security.
6 6-8 System Configuration
6 Advanced Configuration MAC Address Format – MAC addresses can be specified in one of four formats, using no delimeter, with a single dash delimeter, with multiple dash delimeters, and with multiple colon delimeters. VLAN ID Format – A VLAN ID (a number between 1 and 4094) can be assigned to each client after successful authentication using IEEE 802.1X and a central RADIUS server. The user VLAN IDs must be configured on the RADIUS server for each user authorized to access the network.
6 System Configuration CLI Commands for RADIUS – From the global configuration mode, use the radius-server address command to specify the address of the primary or secondary RADIUS servers. (The following example configures the settings for the primary RADIUS server.) Configure the other parameters for the RADIUS server. Then use the show show radius command from the Exec mode to display the current settings for the primary and secondary RADIUS servers. SMC AP(config)#radius-server address 192.168.1.
Advanced Configuration 6 SSH Settings Telnet is a remote management tool that can be used to configure the access point from anywhere in the network. However, Telnet is not secure from hostile attacks. The Secure Shell (SSH) can act as a secure replacement for Telnet. The SSH protocol uses generated public keys to encrypt all data transfers passing between the access point and SSH-enabled management station clients and ensures that data traveling over the network arrives unaltered.
6 System Configuration CLI Commands for SSH – To enable the SSH server, use the ip ssh-server enable command from the CLI Ethernet interface configuration mode. To set the SSH server UDP port, use the ip ssh-server port command. To view the current settings, use the show system command from the CLI Exec mode (not shown in the following example).
Advanced Configuration 6 MAC Authentication – You can configure a list of the MAC addresses for wireless clients that are authorized to access the network. This provides a basic level of authentication for wireless clients attempting to gain access to the network. A database of authorized MAC addresses can be stored locally on the access point or remotely on a central RADIUS server. (Default: Disabled) • Disabled: No checks are performed on an associating station’s MAC address.
6 System Configuration Local MAC Authentication – Configures the local MAC authentication database. The MAC database provides a mechanism to take certain actions based on a wireless client’s MAC address. The MAC list can be configured to allow or deny network access to specific clients. • System Default: Specifies a default action for all unknown MAC addresses (that is, those not listed in the local MAC database).
Advanced Configuration 6 CLI Commands for Local MAC Authentication – Use the mac-authentication server command from the global configuration mode to enable local MAC authentication. Use the mac-authentication session-timeout command to set the authentication interval, and web-redirect command to enable web-based authentication for service billing.
6 System Configuration CLI Commands for RADIUS MAC Authentication – Use the mac-authentication server command from the global configuration mode to enable remote MAC authentication. Set the timeout value for re-authentication using the macauthentication session-timeout command. Be sure to also configure connection settings for the RADIUS server (not shown in the following example). To display the current settings, use the show authentication command from the Exec mode.
Advanced Configuration 6 Filter Control The access point can employ network traffic frame filtering to control access to network resources and increase security. You can prevent communications between wireless clients and prevent access point management from wireless clients. Also, you can block specific Ethernet traffic from being forwarded by the access point.
6 System Configuration Uplink Port MAC Address Filtering Status – Prevents traffic with specified source MAC addresses from being forwarded to wireless clients through the access point. You can add a maximum of four MAC addresses to the filter table. (Default: Disabled) • MAC Address: Specvifies a MAC address to filter, in the form xx-xx-xx-xx-xx-xx. • Permission: Adds or deletes a MAC address from the filtering table.
Advanced Configuration 6 VLAN The access point can employ VLAN tagging support to control access to network resources and increase security. VLANs separate traffic passing between the access point, associated clients, and the wired network. There can be a VLAN assigned to each associated client, a default VLAN for each VAP (Virtual Access Point) interface, and a management VLAN for the access point.
6 System Configuration When setting up VLAN IDs for each user on the RADIUS server, be sure to use the RADIUS attributes and values as indicated in the following table. Number RADIUS Attribute Value 64 Tunnel-Type VLAN (13) 65 Tunnel-Medium-Type 802 81 Tunnel-Private-Group-ID VLANID (1 to 4094 as hexadecimal or string) VLAN IDs on the RADIUS server can be entered as hexadecimal digits or a string (see “radius-server vlan-format” on page 7-64).
Advanced Configuration 6 WDS Settings Each access point radio interface can be configured to operate in a bridge or repeater mode, which allows it to forward traffic directly to other access point units. To set up bridge links between access point units, you must configure the wireless Distribution System (WDS) forwarding table by specifying the wireless MAC address of all units to which you want to forward traffic.
6 System Configuration • Bridge: Operates as a bridge to other access points. The “Parent” link to the root bridge must be configured. Up to five other ”Child” links are available to other bridges. • Repeater: Operates as a wireless repeater, extending the range for remote wireless clients and connecting them to the root bridge. The “Parent” link to the root bridge must be configured. In this mode, traffic is not forwarded to the Ethernet port from the radio interface.
Advanced Configuration 6 Spanning Tree Protocol – STP uses a distributed algorithm to select a bridging device (STP-compliant switch, bridge or router) that serves as the root of the spanning tree network. It selects a root port on each bridging device (except for the root device) which incurs the lowest path cost when forwarding a packet from that device to the root device.
6 System Configuration 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.
Advanced Configuration 6 • Range: 1-65535 • Default: Ethernet interface: 19; Wireless interface: 40 • Link Port Priority – Defines the priority used for this port in the Spanning Tree Protocol. If the path cost for all ports on a switch are the same, the port with the highest priority (i.e., 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.
6 System Configuration CLI Commands for STP Settings – If the role of a radio interface is set to Repeater, Bridge or Root Bridge, STP can be enabled on the access point to maintain a valid network topology. To globally enable STP, use the bridge stp enable command from the CLI configuration mode. Then configure the other global STP parameters for the bridge.
Advanced Configuration 6 AP Management The Web, Telnet, and SNMP management interfaces are enabled and open to all IP addresses by default. To provide more security for management access to the access point, specific interfaces can be disabled and management restricted to a single IP address or a limited range of IP addresses. Once you specify an IP address or range of addresses, access to management interfaces is restricted to the specified addresses.
6 System Configuration CLI Commands for AP Management features. SMC AP(config)#apmgmtip multiple 192.168.1.50 255.255.255.0 SMC AP(config)#apmgmtui SNMP enable 7-21 7-22 Administration Changing the Password Management access to the web and CLI interface on the access point is controlled through a single user name and password. You can also gain additional access security by using control filters (see “Filter Control” on page 6-17).
Advanced Configuration 6 Session Timeout for WEB – Sets the time limit for an idle web interface session. (Range: 0-1800 seconds; Default: 300 seconds; 0 is disabled) CLI Command for the Web Session Timeout – Use the ip http session-timeout command from the CLI configuration mode. SMC AP(config)#ip http session-timeout 0 SMC AP(config)# 7-18 Upgrading Firmware You can upgrade new access point software from a local file on the management workstation, or from an FTP or TFTP server.
6 System Configuration Before upgrading new software, verify that the access point is connected to the network and has been configured with a compatible IP address and subnet mask. If you need to download from an FTP or TFTP server, take the following additional steps: • Obtain the IP address of the FTP or TFTP server where the access point software is stored. • If upgrading from an FTP server, be sure that you have an account configured on the server with a user name and password.
Advanced Configuration 6 Firmware Upgrade Local – Downloads an operation code image file from the web management station to the access point using HTTP. Use the Browse button to locate the image file locally on the management station and click Start Upgrade to proceed. • New firmware file: Specifies the name of the code file on the server. The new firmware file name should not contain slashes (\ or /), the leading letter of the file name should not be a period (.
6 System Configuration Upon uploading a new configuration file you will be prompted to either restore factory settings, or reboot the unit. CLI Commands for Downloading Software from a TFTP Server – Use the copy tftp file command from the Exec mode and then specify the file type, name, and IP address of the TFTP server. When the download is complete, the dir command can be used to check that the new file is present in the access point file system.
Advanced Configuration 6 System Log The access point can be configured to send event and error messages to a System Log Server. The system clock can also be synchronized with a time server, so that all the messages sent to the Syslog server are stamped with the correct time and date. Enabling System Logging The access point supports a logging process that can control error messages saved to memory or sent to a Syslog server.
6 System Configuration Logging Level – Sets the minimum severity level for event logging. (Default: Informational) The system allows you to limit the messages that are logged by specifying a minimum severity level. The following table lists the error message levels from the most severe (Emergency) to least severe (Debug). The message levels that are logged include the specified minimum level up to the Emergency level.
Advanced Configuration 6 CLI Commands for System Logging – To enable logging on the access point, use the logging on command from the global configuration mode. The logging level command sets the minimum level of message to log. Use the logging console command to enable logging to the console. Use the logging host command to specify up to four Syslog servers. The CLI also allows the logging facility-type command to set the facility-type number to use on the Syslog server.
6 System Configuration Note: The access point also allows you to disable SNTP and set the system clock manually. Set Time Zone – SNTP uses Coordinated Universal Time (or UTC, formerly Greenwich Mean Time, or GMT) based on the time at the Earth’s prime meridian, zero degrees longitude. To display a time corresponding to your local time, you must indicate the number of hours your time zone is located before (east) or after (west) UTC.
Advanced Configuration 6 CLI Commands for the System Clock – The following example shows how to manually set the system time when SNTP server support is disabled on the access point. SMC AP(config)#no sntp-server enable SMC AP(config)#sntp-server date-time Enter Year<1970-2100>: 2003 Enter Month<1-12>: 10 Enter Day<1-31>: 10 Enter Hour<0-23>: 18 Enter Min<0-59>: 35 SMC AP(config)# 7-35 7-36 RSSI The RSSI value displayed on the RSSI page represents a signal to noise ratio.
6 System Configuration The RSSI controls allow the external connector to be disabled and the receive signal for each WDS port displayed. RSSI: • Auto Refresh – Enables or disables the refreshing of RSSI information. • RSSI Value – The displayed RSSI value for a selected port.
Advanced Configuration 6 • Port Number: Selects a specific WDS port for which to display the RSSI output value. Ports 1-6 are available for a Master unit, only port 1 for a Slave unit. (Default: 1) Distance: • Mode: Indicates if the 802.11a radio is operating in normal or Turbo mode. (See "Radio Settings A" on page 6-53.) • Distance: The approximate distance between antennas in a bridge link. LED Status • Mode – Selects AP mode or Bridge mode.
6 System Configuration SNMP 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.
SNMP 6 Configuring SNMP and Trap Message Parameters 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 strings to be configured for authentication. Trap notifications can be enabled and sent to up to four management stations. SNMP – Enables or disables SNMP management access and also enables the access point to send SNMP traps (notifications).
6 System Configuration Community Name (Read/Write) – 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) Trap Destination (1 to 4) – Enables recipients (up to four) of SNMP notifications. • Trap Destination IP Address – Specifies the recipient of SNMP notifications. Enter the IP address or the host name.
SNMP 6 Trap Configuration – Allows selection of specific SNMP notifications to send. The following items are available: • sysSystemUp - The access point is up and running. • sysSystemDown - The access point is about to shutdown and reboot. • sysRadiusServerChanged - The access point has changed from the primary RADIUS server to the secondary, or from the secondary to the primary. • sysConfigFileVersionChanged - The access point’s configuration file has been changed.
6 System Configuration • dot11StationDisassociate - A client station no longer associates with the network. • dot11StationAuthenticateFail - A client station has tried and failed to authenticate to the network. • Enable All Traps - Click the button to enable all the available traps. • Disable All Traps - Click the button to disable all the available traps. CLI Commands for SNMP and Trap Configuration – Use the snmp-server enable server command from the global configuration mode to enable the SNMP agent.

6 System Configuration Configuring SNMPv3 Users The access point allows up to 10 SNMP v3 users to be configured. Each user must be defined by a unique name, assigned to one of three pre-defined security groups, and configured with specific authentication and encryption settings. User – The SNMPv3 user name. (32 characters maximum) Group – The SNMPv3 group name. (Options: RO, RWAuth, or RWPriv; Default: RO) • RO – Read-only access. • RWAuth – Read/write access with user authentication.
SNMP 6 CLI Commands for Configuring SNMPv3 Users – Use the snmp-server engine-id command to define the SNMP v3 engine before assigning users to groups. Use the snmp-server user command to assign users to one of the three groups and set the appropriate authentication and encryption types to be used. To view the current SNMP v3 engine ID, use the show snmp command. To view SNMP users and group settings, use the show snmp users or show snmp group-assignments commands.
6 System Configuration Configuring SNMPv3 Trap Filters SNMP v3 users can be configured to receive notification messages from the access 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. The access point allows up to 10 notification filters to be created. Each filter can be defined by up to 20 MIB subtree ID entries.
SNMP 6 Filter ID – A user-defined name that identifies the filter. (Maximum length: 32 characters) Subtree OID – Specifies MIB subtree to be filtered. The MIB subtree must be defined in the form “.1.3.6.1” and always start with a “.”. Filter 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.
6 System Configuration Configuring 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 “Configuring SNMPv3 Trap Filters” on page 6-48) To configure a new notification receiver target, click the New button. A new page opens to configure the settings (see below).
Radio Interface 6 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. Assigned Filter – The name of a user-defined notification filter that is applied to the target. CLI Commands for Configuring SNMPv3 Targets – To create a notification target, use the snmp-server targets command from the CLI configuration mode.
6 System Configuration Each radio supports up to four virtual access point (VAP) interfaces numbered 0 to 3. 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 four VAP interfaces. The VAPs function similar to a VLAN, with each VAP mapped to its own VLAN ID. Traffic to specific VAPs can be segregated based on user groups or application traffic.
Radio Interface 6 Radio Settings A (802.11a) The IEEE 802.11a interface operates within the 5 GHz band, at up to 54 Mbps in normal mode or up to 108 Mbps in Turbo mode. First configure the radio settings that apply to the individual VAPs (Virtual Access Point) and the common radio settings that apply to the overall system. After you have configured the radio settings, go to the Security page under the 802.
6 System Configuration Default VLAN ID – The VLAN ID assigned to wireless clients associated to the VAP interface that are not assigned to a specific VLAN by RADIUS server configuration. (Default: 1) Closed System – When enabled, the VAP interface does not include its SSID in beacon messages. Nor does it respond to probe requests from clients that do not include a fixed SSID.
Radio Interface 6 CLI Commands for the Configuring the VAPs – From the global configuration mode, enter the interface wireless a command to access the 802.11a radio interface. From the 802.11a interface mode, you can access radio settings that apply to all VAP interfaces. To access a specific VAP interface (numbered 0 to 3), use the vap command. You can configure a name for each interface using the description command. You can also use the closed-system command to stop sending the SSID in beacon messages.
6 System Configuration • AP Detection – Enables the periodic scanning for other access points. (Default: Disable) • AP Scan Interval – Sets the time between each rogue AP scan. (Range: 30 -10080 minutes; Default: 720 minutes) • AP 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.

SMC AP(config)#interface wireless g 7-90 Enter Wireless configuration commands, one per line. SMC AP(if-wireless g)#rogue-ap enable 7-116 configure either syslog or trap or both to receive the rogue APs detected.
6 System Configuration Configuring Common Radio Settings To configure common radio settings, select the Radio Settings page, and scroll down to below the VAP radio settings. Turbo Mode – The normal 802.11a wireless operation mode provides connections up to 54 Mbps. Turbo Mode is an enhanced mode (not regulated in IEEE 802.11a) that provides a higher data rate of up to 108 Mbps. Enabling Turbo Mode allows the access point to provide connections up to 108 Mbps.
Radio Interface 6 Radio Channel – The radio channel that the access point uses Normal Mode to communicate with wireless clients. When multiple access points are deployed in the same area, set the channel on neighboring access points at least four channels apart to avoid interference with each other. For example, in the United States you can deploy up to four access points in the same area (e.g., channels 36, 56, 149, 165).
6 System Configuration • Right: The radio uses a single antenna on the right side. Select this method when using an optional external antenna that is connected to the right antenna connector. • Left: The radio uses a single antenna on the left side. Select this method when using an optional external antenna that is connected to the left antenna connector. Also select this method when using the integrated 5 GHz antenna.
Radio Interface 6 Multicast Data Rate – The maximum data rate at which the access point transmits multicast and broadcast packets on the wireless interface. (Options: 24, 12, 6 Mbps; Default: 6 Mbps) Fragmentation Length – Configures the minimum packet size that can be fragmented when passing through the access point. Fragmentation of the PDUs (Package Data Unit) can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size.
6 System Configuration CLI Commands for the Common Radio Settings – From the global configuration mode, enter the interface wireless a command to access the 802.11a radio interface. From the 802.11a interface mode, you can access radio settings that apply to all VAP interfaces. Use the turbo command to enable this feature before setting the radio channel with the channel command. Set any other radio setting as required before enabling the VAP interface (with the no shutdown command).
Radio Interface 6 types of traffic, WMM allows the priority levels to be configured to match any network-wide QoS policy. WMM also specifies a protocol that access points can use to communicate the configured traffic priority levels to QoS-enabled wireless clients. Table 6-1. 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.

WMM Backoff Wait Times 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. To configure WMM, select the Radio Settings page, and scroll down to the WMM configuration settings.
Radio Interface 6 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: Support) • Disable: WMM is disabled. • Support: WMM will be used for any associated device that supports this feature. Devices that do not support this feature may still associate with the access point.
6 System Configuration CLI Commands for WMM – Enter interface wireless mode and type wmm required for clients that want to associate with the access point. The wmm-acknowledge-policy command is used to enable or disable a policy for each access category. The wmmparms command defines detailed WMM parameters.

Radio Interface 6 Enabling the VAPs Before enabling the Virtual Access Point (VAP) radio interfaces, first configure all of the relevant raido settings (see “Radio Settings A (802.11a)” on page 6-53 or “Radio Settings G (802.11g)” on page 6-68.) After you have configured the radio settings, select Security under Radio A or Radio G, set an SSID to identify the wireless network service provided by each VAP you want to use, and then click Apply to save your settings.
6 System Configuration 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.
Radio Interface 6 To enable WEP shared keys for a VAP interface, click Security under Radio A or Radio G. Then, select the VAP interface that will use WEP keys by clicking More, and configure the Authentication Type Setup and Encryption fields. Authentication Type Setup – Sets the access point to communicate as an open system that accepts network access attempts from any client, or with clients using pre-configured static shared keys.

6 System Configuration 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. Mixed WPA and WEP Client Support: WPA enables the access point to indicate its supported encryption and authentication mechanisms to clients using its beacon signal. WPA-compatible clients can likewise respond to indicate their WPA support.
Radio Interface 6 information form a Security Association that the access point names and holds in a cache. • Preauthentication: Each time a client roams to another access point it has to be fully re-authenticated. This authentication process is time consuming and can disrupt applications running over the network. WPA2 includes a mechanism, known as pre-authentication, that allows clients to roam to a new access point and be quickly associated.
6 System Configuration The WPA configuration parameters are described below: Encryption – You must enable data encryption in order to enable all types of encryption (WEP, TKIP, or AES) in the access point. Pre-Authentication – When using WPA2 over 802.1X, 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.
Radio Interface 6 The configuration settings for WPA are summarized below: Table 6-4. WPA Configuration Settings WPA and WPA2 pre-shared key only WPA and WPA2 over 802.
6 System Configuration CLI Commands for WPA Over 802.1X Security – From the VAP interface configuration mode, use the auth wpa required command to select WPA over 802.1X security. Then set the 802.1X key refresh rates. To view the current security settings, use the show interface wireless a [0-3] or show interface wireless g [0-3] command (not shown in example).

7 Command Line Interface Rogue AP Detection Commands 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 potentially allow unauthorized users access to the network. Alternatively, client stations may mistakenly associate to a rogue AP and be prevented from accessing network resources. Rogue APs may also cause radio interference and degrade the wireless LAN performance.
Rogue AP Detection Commands 7 • A “rogue AP” is either an access point that is not authorized to participate in the wireless network, or an access point that does not have the correct security configuration. Rogue access points can be identified by unknown BSSID (MAC address) or SSID configuration. A database of nearby access points should therefore be maintained on a RADIUS server, allowing any rogue APs to be identified (see “rogue-ap authenticate” on page 77-117).
7 Command Line Interface rogue-ap duration This command sets the scan duration for detecting access points. Syntax rogue-ap duration milliseconds - The duration of the scan. (Range: 100-1000 milliseconds) Default Setting 350 milliseconds Command Mode Interface Configuration (Wireless) Command Usage • During a scan, client access may be disrupted and new clients may not be able to associate to the access point.

Syntax transmit-key index - Key index. (Range: 1-4) Default Setting 1 Command Mode Interface Configuration (Wireless-VAP) Command Usage • If you use WEP key encryption option, the access point uses the transmit key to encrypt multicast and broadcast data signals that it sends to client devices.
7 Command Line Interface cipher-suite This command defines the cipher algorithm used to encrypt the global key for broadcast and multicast traffic when using Wi-Fi Protected Access (WPA) security. Syntax multicast-cipher • aes-ccmp - Use AES-CCMP encryption for the unicast and multicast cipher. • tkip - Use TKIP encryption for the multicast cipher. TKIP or AES-CCMP can be used for the unicast cipher depending on the capability of the client.
Wireless Security Commands 7 • AES-CCMP (Advanced Encryption Standard Counter-Mode/CBCMAC Protocol): WPA2 is backward compatible with WPA, including the same 802.1X and PSK modes of operation and support for TKIP encryption. The main enhancement is its use of AES Counter-Mode encryption with Cipher Block Chaining Message Authentication Code (CBC-MAC) for message integrity. The AES Counter-Mode/CBCMAC Protocol (AES-CCMP) provides extremely robust data confidentiality using a 128-bit key.
7 Command Line Interface Example SMC AP(if-wireless a)#mic_mode hardware SMC AP(if-wireless g)# wpa-pre-shared-key This command defines a Wi-Fi Protected Access (WPA/WPA2) Pre-shared-key.

Troubleshooting If you cannot access the on-board configuration program via a serial port connection: • Be sure you have set the terminal emulator program to VT100 compatible, 8 data bits, 1 stop bit, no parity and 9600 bps. • Check that the null-modem serial cable conforms to the pin-out connections provided on page B-3. 4. If you forgot or lost the password: 5.
Appendix B: Cables and Pinouts Twisted-Pair Cable Assignments For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.
B Cables and Pinouts Table B-1. 10/100BASE-TX MDI Port Pinouts Pin MDI Signal Name 1 Transmit Data plus (TD+) 2 Transmit Data minus (TD-) 3 Receive Data plus (RD+) 4 GND (Positive Vport) 5 GND (Positive Vport) 6 Receive Data minus (RD-) 7 -48V feeding power (Negative- Vport) 8 -48V feeding power (Negative- Vport) Note: The “+” and “-” signs represent the polarity of the wires that make up each wire pair.
Twisted-Pair Cable Assignments B Crossover Wiring Because the 10/100 Mbps port on the access point uses an MDI pin configuration, you must use “crossover” cable for network connections to PCs, servers or other end nodes that only have MDI ports. However, if the device to which you are connecting supports auto-MDIX operation, you can use either “straight-through” or “crossover” cable.
B Cables and Pinouts 8-Pin DIN to RJ-45 Cable Wiring To construct an extended Ethernet cable to connect from the power injector’s RJ-45 Output port to the wireless bridge’s 8-pin DIN connector, follow the wiring diagram below. Use Category 5 or better UTP or STP cable, maximum length 100 m (328 ft), and be sure to connect all four wire pairs. Note: To construct a reliable Ethernet cable, always use the proper tools or ask a professional cable supplier to construct the cable.
