Chapter 1: Introduction

The 2.4 GHz/5 GHz Wireless Access Point is an IEEE 802.11a/g access point that provides transparent, wire le ss hig h- speed data communications between the wired LAN and fixed or mobile devices equipped with an 802.11a, 802.11b, or 802.11g wireless adapter.

This solution offers fast, re liable wireless c onnectivity with co nsiderable cost savings over wired LANs (which include long-term maintenance overhead for cabling). Using

802.11a and 802.11g technology, this access point can easily repl ace a 10 Mbps Ethernet connection or se am lessly integrate into a 10/100 M bps Eth er net LAN.

The access point supports up to ei ght Virtual Acc ess Points per physical radio interface, that is eight on the 802. 11a radio and eight on the 802.11g radio. This allows traffic to be separated for different user groups using an access point t hat services one area. For each VAP, different security settings, VLAN assignments, and other parameters can be appl ied.

Each radio interface on the access point can operate in one of four modes:

• Access Point – Providing conectivity to wireless clie nt s in th e service area.

• Repeater – Providing an extended link to a remote access point from the wired LAN. In this mode, the access point does not have a cable connection to the wired Ethernet LAN.

• Bridge – Providing links to access points operating in “Bridge” or “Roo t Bri dge ” mode and thereby connecting other wired LAN segments.

• Root Bridge – Providing links to other access points operating in “Bridge” mode and thereb y connecting other wir ed LAN segments. Only one un it in the wireless bridge network can be set to “Root Bridge” mode.

In addition, the access point offers full network management capabilities through an easy to configure web in te rface, a command line interfa ce for ini tial co nf ig ur at io n and troubleshooting, and su pport for Simple Network M anagement Protocol tool s.

Radio Characteristics – The IEEE 802.11a/g standard uses a radio mod ul at i on technique known as Orthogonal Frequency Division Multiplexing (OFDM) , and a shared collision domain (CSM A/CA). It operates at the 5 GH z U nl icensed National Information Infrastru ct ur e (UNII) band for connections to 802.11a clients, and at 2.4 GHz for connections to 802.11g clients.

IEEE 802.11g includes backward compatibility with the IE EE 802.11b standard. IEEE 802.11b also operates at 2.4 GHz, but uses Direct Se qu ence Spread Spectrum (DSSS) and Complementary Code Keying (CCK) modulation t echnology to achieve a communication rate of up to 11 Mbps.

The access point supports a 54 M bps half -d upl ex connection to Ethernet ne t w or ks for each active channel (o r up to 108 M bps w hen using turbo mode on the 802.11a interface).

Component Description

Antennas

The access point includes integrated diversity antennas for wireless communications. A diversity antenna system uses two identical antennas to receive and transmit signals, he lpi ng t o av oi d m ul t ipath fadi ng effects. When receiving, the access point checks bot h antennas and selects the on e wi th the st ro ngest signal. When transmitting, it will continue to use the antenna previously selected for receiving. The access point never transmits from both antennas at the same time.

The antennas transmit the outgoing signal as a toroidal sphere (doughnut shape d) , with the coverage extend ing most in a direction perp endicular to t he antenna. Th e antenna should be adjus te d to an angle that provides the appr op riat e coverage for the service area. For further information, see “Positionin g th e Ant ennas” on 2-2.

LED Indicators

The access point includes four status LED indicators, as described in the following figure and table.

Security Slot

The access point includes a Kensington security slo t on th e re ar panel. You can prevent unauthorized removal of the access point by w r apping the Kensington securit y cab le (n ot pr ov id ed ) ar oun d an un mo va bl e object, inserting th e lo ck in to th e slot, and turning the key.

Console Port

This port is used to connect a con sole device to the access po int through a serial cable. This connection is described under “Co nsole Port Pin Assignments” on page B-3. The console device can be a PC or wo rk station running a VT-100 terminal emulator, or a VT-100 terminal.

Ethernet Port

The access point has one 10BASE-T/100BASE-TX RJ-45 port that can be attached directly to 10BASE-T/100BASE-TX LAN segments. These segments must conform to the IEEE 802.3 or 802.3u spe cif ic ati ons.

This port uses an MDI (i.e., inte rn al st ra ig ht -through) pin configuration . You can therefore use straight-through twisted-pair cable to connect this port to most network interconnection devices such as a switch or router tha t provide MDI-X ports. However, when connecting the acce ss point to a workstation or othe r de vi ce that does not have MDI-X po rts, you mu st use crossover twisted-pair ca ble.

The access point appears as an Ethernet node and perfor ms a bridging function by moving packets from the wired LAN to remote workstations on t he w ir el ess infrastructure.

Features and Benefits

Note: The RJ-45 port also supports Power over Ethernet (PoE) based on the IEEE

802.3af standard. Refer to the description for the “Power Connector” for information on supplying power to the access point’s network port from a network device, such as a switch, that prov ides Power over Et hernet (PoE).

Reset Button

This button is used to reset the access point or restore the factory default configuration. If you hold down the button for less than 5 seconds, the access point will perform a hardware res et . If you hold down the button for 5 seconds or more, any configuration changes you may have made are removed, and the factory default configuration is restor ed to the access point.

Power Connector

The access point does not have a power switch. It is powered on when connected to the AC power adapter, and the power adapter is connected to a power sourc e. The power adapter automat i cally adjusts to any voltage betw een 100-240 volts at 50 or 60 Hz. No voltage range settings are required.

The access point may also r eceive Power over Ethernet (PoE) from a switch or other network device that supplies power over the network cable based on the IEEE

802.3af standard. Note that if the access poi nt is connected to a PoE source dev ic e an d al so

connected to a local power source through the AC power adapter, PoE will be disabled.

Chapter 2: Hardware Installation

1. Select a Site – Choose a proper place for the access point. In general, the best location is at the center of your wireless coverage area, within line of sight of all wireless devices. Try to place the access poi nt in a posi tion that can best c over its Basic Service Set (refer to “Infrastructure Wireless LAN” on page 4-3). For optimum performance, consider these points:

• Mount the access point as high as possible above any obstructions in the

coverage area.

• Avoid mounting next to or near building support columns or other obstructions

that may cause reduced signal or null zones in parts of the coverage area.

• Mount away from any signal absorbing or reflecting structures (such as those

containing metal).

2. Mount the Acc ess Point – The access point can be mounted on any horizontal surface.

Mounting on a horizontal surface – T o keep the access point from sliding on the surface, attach the four rubber feet provided in the accessory kit to the marked circles on the bottom of th e ac cess point.

Lock the Access Point in Plac e – To prevent unauthorized removal of t he access point, you can use a Kensington Slim MicroSaver security cable (not included) to attach the acc e ss po int to a fixed object.

3. Connect the Pow er Cord – Conne ct the power adapter to the access po in t , and the power cord to an AC pow er out let .

Otherwis e, the access poi nt can derive its operat ing power dire ctly from the RJ-45 port when connected to a device that provide s IEEE 802.3af compliant Power over Ethernet (PoE).

Note: If the access point is connected to both a PoE source device and an AC power

source, PoE will be disabled.

Caution: Use ONLY the power adapter supplied with this access point. Otherwise, the

product may be damaged.

2-1

Hardware Installation

4. Observ e t he Sel f Test – When you power on the access point, verify that the PWR indica tor st op s fl ashi ng an d rema ins o n, and that the othe r indi cat ors sta rt functioning as described under “LED Indicators” on page 1-3. If the PW R LED does not stop flashing, the self test has not completed correctly. Refer to “Troubleshooting” on page A-1.

5. Connect the Et her net C able – The access point can be wired to a 10/100 Mbps Ethernet through a network device such as a hub or a swi tc h. C onnect your network to the RJ-45 por t on th e back panel with category 3, 4, or 5 UT P Ethernet cable. When th e acc ess point and the connected device are powered on, the Ethernet Link LED should light indicating a valid net work connection. If this LED fails to turn on refer to “Troubleshooti ng ” on page A-1 .

Note: The RJ-45 port on the access point uses an MDI pin configuration, so you must

use straight-through cable for network connections to switches that only have MDI-X ports, and crossover cable for network connections to PCs, servers or other devices that only have MDI ports. However, if the connected device supports auto-MDI/MDI-X operation, you can use either straight-through or crossover cable.

6. Position the Antenn as – Each antenna emits a radiation pattern that is toroidal (doughnut shaped), with the coverage extending most in the direction perpendi cular to the antenna. Ther efore, the antennas should be oriented so that the radio coverage patter n f ills t he intended horizontal space. Also, the diversity antennas should both be positioned alo ng t he same axes, providing the same coverage area. For example, if the access point is mounted on a horizontal surface, both ant en nas should be positioned pointing vertically up to provide optimum coverage.

7. Connect the Cons ole Por t – Co nnect the console cable (included) to the RS-232 console port for accessing the command- line interface. You can manage the ac cess point using the conso le port (Chapter 6), the web interface (Chapter 5), or SNMP management software such as HP’s OpenView.

Chapter 3: External Antennas

The SMC WA6102X-2AG provides a variety of external antenna options for extending the radio range and shaping the cover ge area. These an tennas of fer a number of different mounting locations, including indoor or outdoor, wall, ceiling, or radio mast.

This chapter shows you how to install an external antenna for your WA6102X-2AG.

Only the SMC antennas listed in this guide are permitted to be connected to the WA6102X-2AG. You must use the appropriate antennas, cables, and where applicable, surge arrestors, for your given region. You are responsible for verifying local regulations or legi slation that may impose restri ctions on the use of specific antenna and cable combinations. For this reason, SMC recommends that you consult with a professional installer who is trained in RF installation and knowledgeable in the local regulations prior to connecting an external antenna to your wireless radio product. It is the responsibility of the end user to ensure that the antenna installation complies with the local radio regulations.

Instalation Procedures

Follow these steps to install an exte rn al ant enna and connect it to the WA6102X-2AG.

Caution: Never mount the access point outdoors to be near an external antenna.

1. Plan the Installation

The access point must always be installed indoors.

• Pigtail Cables - Use the coax pigtail cable attached to the antenna to connect to the access point. Because most pigtail cables are a relatively short length (83 cm or 33 inches), be sur e to find a suitable mounting posit io n for the antenna that is not too far from the access point. If an extension cable is required, please cont act a professional installer who is trained in RF installation and knowledgeable in the local regul at ions.

• Installation Location - Plan t he an te nna’s position and orient at ion.

Warning: The radiated output power of this device is below the FCC radio

exposure limits. Nevertheless, the device should be used in such a manner that the potential for human contact during normal operation is minimized. To avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antennas should not be less than 20 cm (8 inches) during normal operation.

3-1

External Antennas

Consider these points:

• Use the antenna’s mounti ng bracket or other hardwar e, if in cluded.

• For optimum performance, mount antennas as high as possible above any

obstructions, and awa y f rom any signal absorbing or ref le ct ing structures (such as those containing metal)

• Be sure there are no other radio ant enn as mounted within 2 m (6 ft).

• Consider the antenna’s radio coverage pattern so that it can properly cover

the intended service area.

• Omnidirectional Antennas - Consider these factors when selecting a location for these antennas:

• Always mount the antenna in a vertical orientation so that th e ra di o

coverage pattern fills the i nt ended horizontal space.

• For optimum coverage, mount the antenna at the center of the area with a

line-of-sight path to all point s w it hi n th e ar ea.

• Avoid mounting next to or nea r bu ildi n g support columns or other

obstructions that ma y cause reduced signal or null z ones in parts of the coverage area.

• When mounting outdoors using a mast, make sure that the antenna extends

beyond the top of the mas t.

• Directional Antennas - Consider t hes e fa ct or s whe n se le ct in g a lo ca ti on for these antennas:

• For optimum coverage, m ount the antenna above any obstructions,

directed at the center of th e coverage area sector.

• High-gain directional ante nnas provide a flattened rad io cov erage pattern

in the horizontal plane. Us e th e t iltin g or arti culated mounts to point the antennas towards th e cov er age area.

• Outdoor Installation - When installing an antenn a out doors, be sure to consider these addit ional f act or s:

• Always place the antenna aw ay from power and telephone lines

• Make sure that the antenn a, any supporting structure, and cables are all

properly grounded.

• For lightning protection, con si der us in g a l ight ni ng arrestor immediately

before the cable enters th e building.

Warning: Never install an antenna or construct a radio mast near overhead

power lines.

2. Mount the Antenn a

Install the antenna in its planned location using the brackets, clips, or other hardware included in the antenna package.

Refer to documentation incl uded with the antenna for sp eci f ic in f ormation and installation instructions.

3-2

Instalation Procedures

3. Connect Pigtail Cables to the Access Point

Use the pigtail cables that are at tache d t o th e antenna, or are included in the antenna package. If an extension cable is required, plea se contact a professional installer who is trained in RF installation and knowledgeable in the local regulations.

Note that diversity antennas have two pigtail cables. A diversity antenna includes two internal antenna elements that are identical. Both antenna pigtail cables must be connected to the acce ss point for correct operati on.

Other non-diversity an te nnas, which have only one pi gtail cable, attach to the access point’s right antenna c onnector. The access point’s right antenna is the one on the side closest to the LE D in dicat or s. When using a non-diversi t y antenna, a 50-ohm terminator (in cl uded with the antenna) mu st be connected to the access point’s left antenna connector.

To connect pigtail cables to the acce ss point, follow these steps:

1. Disable the access point radio using the w eb br ow s er interface, CLI, or SNMP.

2. Remove p ow er to th e access point.

3. Remove b ot h of th e access point’s antennas by uns cr ewi ng them at their base.

Chapter 4: Network Configuration

Wireless networks su pport a stand-alone configurat i on as well as an integrated configuration with 10/10 0 Mbps Ethernet LANs. The 2. 4 G Hz/ 5 G H z Wi r eless Access Point also provide s re peater and bridging servic es t hat can be configured independently on either th e 5 GH z or 2.4 GHz radio interfaces .

Access points can be deployed to support wireless clients and connect wired LANs in the following configurat i ons:

• Ad hoc for departmental, SOHO or enterpris e LAN s

• Infrastructure for wireless LAN s

• Infrastructure wireless LAN for roaming wireless PCs

• Infrastructure wireless b ridge to connect wired LANs

• Infrastructure wireless repeater for extended range

The 802.11b and 802.11g frequency band which operates at 2.4 GHz can easily encounter interferen ce f ro m other 2.4 GHz devices, suc h as other 802.11b or g wireless devices, cordless phones and microwave ovens. If you experience poor wireless LAN perform ance, try the following meas ur es:

• Limit any possible sources of radio interference within the service area

• Increase the distance between n ei ghb or in g access points

• Decrease the signal strength of nei ghboring access points

• Increase the channel separation of neighboring access po in ts (e.g . up to 5

channels of separation for 802 .11b and 802.11g)

Infrastructure Wireless LAN

The access point also provides access to a wir ed LAN for wireless work stations. An integrated wired/wireless LAN is called an Infrastruct u re c onf i guration. A Basic Service Set (BSS) consists of a gr oup of wi r eless PC users, and an access poi nt that is directly connected to the wired LAN. Each wireless PC in this BSS can talk to any computer in its wireless group via a radio link, or access other computers or network resources in t he wi re d LAN infrastructure via th e acc ess point.

The infrastructure configuration not only extends the accessibility of wireless PCs to the wired LAN, but also increases the effective wireless transmission range for wireless PCs by passing their signal through one or more access points.

A wireless infrastructur e c an be used for access to a cent ra l databa se , or fo r connection between mo bi l e workers, as shown in the follo wi ng f ig ur e.

Infrastructure Wireless LAN for Roaming Wireless PCs

The Basic Service Set (BSS) defines the communications domain for each access point and its associated wirele ss cl ients. The BSS ID is a 48-bit binary number based on the access po int ’s wirel es s M A C add ress, and is set automati call y and transparently as clients associa te w i th the access point. The BSS ID is used in frames sent between t he access point and its clients to iden tify t ra ffic in the ser vi ce area.

The BSS ID is only set by the access point, never by its clients. The clients on ly need to set the Service Set Iden tifi er (SSID ) that ide nti fies the ser vice set provided by one or more access points. The SSID can be m anually configured by the clien ts, can be detected in an access point’s beacon, or can be obtained by querying for the identity of the nearest access point. For clients that do not need to roam, set the SSID for the wireless card to that used by the access point to which you want to connect.

A wireless infrastructure can also support roaming for mobile workers. More than one access point can be conf igured to create an Extended S er vice Set (ESS). By placing the access poi nts so tha t a c ont i nuous coverage area is creat ed, wireless users within this ESS can roam freely. All wireless network cards and adapters and wireless access points within a specific ESS must be configured with the same SSID.

Infrastructure Wireless Bridge

The IEEE 802.11 standard defines a WIreless Distribution System (WDS) for bridge connections between BSS areas (access points). The access point uses WDS to forward traffic on links between units.

The access point suppo rts WDS br i dge links on either the 5 GHz (802.11a) or

2.4 GHz (802.11b/g) bands and can be used with various external antennas to offer

flexible deployment opti ons. Up to six WDS bridge links can be specified for each unit in th e wi re le ss bridge

network. One unit only must be configured as the “root bridge” in the wireless network. The root bridge sh oul d be the unit connected to the mai n core of the wired LAN. Other bridges must configure one “parent” link to the root bridge or to a bridge connected to the root bridge. The other five available WDS links can be specified as “child” links to other bridges. This forms a tiered-star topology for the wireless bridge network.

When using WDS on a radi o band, only wireless bridge uni ts ca n ass ociate to each other. Wireless clients can only associate with the access point using a radi o band set to access point or repea t er m ode.

Chapter 5: Initial Configuration

The 2.4 GHz/5 GHz Wireless Access Point offers a variety of management options, including a web-based i nte r f ace , a direct connection to the cons ol e po rt , Telnet, Secure Shell (SSH), or using SNMP software.

The initial configuration steps can be made through the web browser interface or CLI. The access point requests an IP address via DHCP by default. If no response is received from the DHCP server, then the access point uses the default address

192.168.1.1. If this address is not compatible with your network, you can first use the command line interfac e (C L I) as d escribed below to configu re a val id address.

Note: Units sold in countries outside the United States are not configured with a specific

country code. You must use the CLI to set the country code and enable wireless operation (page 5-3).

Initial Setup through the CLI

Required Connections

The access point provides an RS-232 serial port that en abl es a connection to a PC or terminal for monitoring and configuration. Attach a VT100-compatible terminal, or a PC running a terminal emul at ion program to the access point . You can use the console cable provide d w i th th is package, or use a cable that com pli es w i t h the wiring assignments shown on page B-3.

To connect to the console port, co m pl et e the following steps:

1. Connect the con sol e c abl e t o t he serial port on a terminal, or a PC run ni ng terminal emulation software, and tighten the captive retaining screws on the DB-9 connector.

2. Connect the oth er end of the cable to the RS-232 se rial port on the access point.

3. Make sure the terminal emulation software is set as follows:

• Select the appropri ate serial port (COM port 1 or 2) .

• Set the data rate to 9600 baud.

• Set the data format to 8 data bits, 1 stop bit, and no parity.

• Set flow control to none.

• Set the emulation mode to VT10 0.

• When using HyperTermin al , s elect Terminal keys, not Wind ow s k eys.

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. However, if you are not using a DHCP server to configure IP addressing, use the CLI to manually configure the initial IP values (see page 5-2). After y ou have network access to th e access point, you can use the web brow ser in te rface to modify the initial IP co nf iguration, if needed.

Note: If there is no DHCP server on your network, or DHCP fails, the access point will

automatically start up with a default IP address of 192.168.1.1.

DHCP Client (Enable) – Select this option to obtain the IP settings for th e access point from a DHCP (Dynamic Host Configuration Protocol) server. The IP address, subnet mask, default ga te way, and Domain Name Se rv er (DNS) address are dynamically assigned to the access point by the network DHCP server. (Default: Enabled)

DHCP Client (Disable) – Select this option to manually configure a static address for the access point.

• IP Address: The IP address of the access point. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods.

6-5

System Configuration

• Subnet Mask: The mask that identifies the host address b its us ed for routing to specific subnets.

• Default Gateway: The defaul t gat ew ay is the IP address of the rout er fo r the access point, which is used if the requested destination address is not on the local subnet.

If you have management st at ions, DNS, RADIUS, or othe r 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).

• 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. Otherwise, leave the addresses as all zeros (0.0.0.0).

CLI Commands for TCP/IP Settings – From the global configuration mode, enter the interface configuration mode with the interfac e et hernet command. Use t he ip dhcp command to enable the DHCP client, or no ip dhcp to disable it. To manually configure an address, specify the new IP address, subnet mask, and default gateway using the ip address command. To specify DNS server addresses use the dns server command. Then use the show interface ethernet command from t he Exec mode to display the current IP settings.

RADIUS

Remote Authentication D ial - in User Ser vi ce (RAD I US) is an authentication protocol that uses software running on a central server to contr ol access to RADIUS-awar e devices on the network. An authentication server co ntains a datab ase 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. A secondary RADIUS ser ve r m ay als o be specified as a backup should the primary server fail or become inaccessible.

In addition, the configured R A DI U S server can also act as a RADI US Accounting server and receive user -s ession accounting info rmation from the access poin t . RADIUS Accounting c an be used to provide valuable inf or m at io n on user activity in the network.

Note: 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 document ation provided with the RADIUS server software.

System Configuration

6-8

Advanced Configuration

Primary Radius Server Setup – Configure the following settings to use RADIUS authentication on the ac cess point.

• IP Address: Specifies the IP address or host name of the RADIU S server.

• Port: The UDP port number used by the RADIU S 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 s paces in the string. (Maximum length: 255 characte rs )

• Timeout: Number of seconds the access point waits for a reply from the RADIUS server before resending a request. (Range: 1-60 seconds; Default: 5)

• Retransmit attempts: The number of times the access point tries to resend a request to the RADIUS server before authentication fails. (Range: 1-30; Default: 3)

• Interim Update Timeout: The interval between transmitting accounting updates to the RADIUS server. (Range: 60-86400; Defau lt: 3600 seconds)

Note: For the Timeout and Retransmit attempts fields, accept the default values unless

you experience problems connecting to the RADIUS server over the network.

Secondary Radius Server Setup – Configure a secondary RADIUS server to provide a backup in case the prim ar y server fails. The access poin t uses the secondary server if the primary server fails or becomes inaccessible. Once the access point switches over to the sec ondary server, it periodically attempts to establish communication aga in w i th prim ar y server. If communication with the primar y server is re-established, the secondary server reverts to a backup role.

SSH Settings

Teln et is a remote management tool tha t can be used to configure the acc ess point from anywhere in the ne twork. However, Telnet is not secure from hostile attacks. The Secure Shell (SSH) can act as a se cur e r epl acement for Telnet. The SSH protocol uses generated public keys to encrypt all data tra nsfers passing between the access point and SSH -e nabled management station cl ie nts and ensures that data traveling over the netw or k ar rives unaltered. Clients can th en securely use the local user name and password for access authentication.

Note that SSH client software nee ds to be installed on the manageme nt statio n to access the access poi nt for m anagement via the SSH proto col.

Notes: 1. The access point supports only SSH version 2.0.

2. After boot up, the SSH server needs about two minutes to generate host

encryption keys. The SSH server is disabled while the keys are being generated.

SSH Settings

• SSH Server Status: Enables or disables t he SSH server. (Default: Enabled)

• SSH Server Port: Sets the UDP port for the SSH server. (Range: 1-65535; Default: 22)

CLI Commands for SSH – To enable the SSH server, use the ip ssh-server enable command from the CLI Et her ne t inter f ace 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 i n the following example).

Authentication

Wireless clients can be auth ent i cat e d for network access by checki ng their MAC address against the local database configured on the ac cess point, or by using a database configured on a ce nt ra l RADIUS server. Alternatively, authentication can be implemented using the IEEE 802.1X network access control protocol.

A client’s MAC address provides relatively weak user aut hen tication, since MAC addresses can be easily captured and used by anot her station to break into the network. Using 802.1X pr ov id es more robust user authe ntic at i on us i ng user names and passwords or digital certificates. You can configure the access point to use both MAC address and 802.1X authentication, with client station MAC authentication occurring prior to IEEE 802.1X authentication. However, it is better to choose one or the other, as appropriate.

Take note of the following points befor e configuring MAC addres s or 802. 1X authentication:

• Use MAC address authentication for a small network w ith a li m ited number of users. MAC addresses can be manually confi gured on the access point itse lf without the need to set up a RADIUS server, but managing a large number of MAC addresses across many access points is very cumbersome. A RADIUS server can be used to centrally manage a larger database of user MAC addresses.

• Use IEEE 802.1X authentication for networks with a larger number of users and where secu r ity is the mo st importan t i ssue. When using 802.1X authentica t i on, a RADIUS server is required in the wired network to centrally manage the credentials of the wireless clients. It also provides a mechanism for enhanced network security using dynamic encryption key rotation or W-Fi Protected Access (WPA).

Note: If you configure RADIUS MAC authentication together with 802.1X, RADIUS MAC

address authentication is performed prior to 802.1X authentication. If RADIUS MAC authentication succeeds, then 802.1X authentication is performed. If RADIUS MAC authentication fails, 802.1X authentication is not performed.

• The access point can als o ope rate in a 802. 1X s uppl ican t mo de. T his enabl es the access point itself to be authenticated with a RADI US ser ve r using a configured MD5 user name and password. This prevents rog ue access points from gaini ng access to the network.

Note: The 802.1X supplicant mode is only configurable using the CLI.

6-12

Advanced Configuration

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 cli ents 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 perfor med on an associating sta tion’s MAC address.

• Local MAC: The MAC address of the associating station is compared against the local database stored on t he access point. Use the Lo cal MAC Authentication section of this web page to se t up th e l oca l d at abase, and configure all access points in the wireless network service area with the same MAC address database.

• Radius MAC: The MAC address of the associating station is sent to a configured RADIUS server for au thent i cation. When using a RADIU S authentication server for MAC ad dre ss a ut hen ti cat i o n, th e se rv er mu st fi r st be co nf ig ur ed i n t he R adius window (see “RADIUS” on page 6-7). The database of MA C addresses and filtering policy must be de f ined i n t he R ADIUS server.

Note: MAC addresses on the RADIUS server can be entered in four different formats

(see “radius-server radius-mac-format” on page 7-63).

6-13

System Configuration

MAC Authentication Session Timeout – Sets the interval at which associated clients will be re-authenticate d wi th the R AD I US server. (Range: 0-1440 minutes; Default : 0, that is, disabled)

WEB Redirect – Enables web-based authentication of wireless clients. This feature supports billing for a public access wireless network without requiring 802.1X or MAC authentication. After suc ces sf ul association to an access po i nt, a c lient is “redirected” to an acces s point login web page as soon as Internet access is attempted. The client is then authenticated by entering a user name and password on the web page. Authentication is determined by checking these credentials against a database of user names and passwords stored n a RADIUS server that is attached to the wired networ k. Fo r infor m at ion on configuring the RADIU S server’s details on the access point, se e “RADIUS Client” on page 6-54. (De fa ul t: Di sa bl ed)

Note: Enabling Web Redirect will cause the system to reboot after 5 seconds.

Local MAC Authentication – Configures the local MAC authentication database. The MAC database provides a me chanism to take certain actions ba sed on a wireless client’s MAC address. The MA C lis t ca n be configured to allow or deny net w or k access to specific clients.

• System Default: Specifies a def aul t act ion f or al l un known MAC addresses (that is, those not listed in the local MAC database).

• D en y: Bl ocks access for all MAC addr ess es except those listed in the lo cal

database as “Allow.”

• Al l ow : Per mits access for all MAC addr esses except those list ed i n th e local

• MAC Authentication Settings: E nter s 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. If Delete is

selected, the specified MAC address entry is rem oved from the database.

Note the following points about the access point’s VLAN supp or t:

• The management VLAN is for man ag in g t he ac cess point through remote management tools, such as the web interface, SSH, SNMP, or Telnet. The access point only accepts management traffic that is tagg ed wit h t he specified management VLAN ID.

• All wireless clients associated to the access point are assigned to a VLAN. If IEEE

802.1X is being used to authenticate wireless clients, specific VLAN IDs can be configured on the RADI US server to be assigned to eac h cl ient . If a cl i ent is not assigned to a specific VLAN or if 802.1X is not used, the client is assigned to the default VLAN for the VAP interfa ce wi t h whi ch it is associated. The access po i nt only allows traffic tagged with assigned VLAN IDs or default VLAN IDs to access clients associated on ea ch VAP interface.

• When VLAN support is enabled on th e ac cess point, traffic passed to th e w ired network is tagged with the appropriate VLAN ID, either an assigned client VLAN ID, default VLAN ID, or the management VLAN ID. Traffic receiv ed 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 t ag is dropped.

• When VLAN support is disabled, th e access point does not tag traff i c passed to the wired network and ignores the VLAN tags on any rece iv ed 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, default VLAN IDs, and other client VLAN IDs. Otherwise, connectivity to the access point will be lost when you enable the VLAN feature.

Using IEEE 802.1X and a cen t ral RA DI U S server, up to 64 VLAN IDs can be mapped to specific wirel ess clients, allowing users to remai n w ith in th e sam e VLAN as they move around a campus site. This feature can also be used to control access to network resources f rom clients, thereby improving security.

A VLAN ID (1-4094) can be ass i gned to a client after successful IEEE 802.1X authentication. The client VLAN IDs must be configured on t he RA DIUS server for each user authorized to access the network. If a client does not have a configured VLAN ID on the RADIUS server, the access point assigns the client to the configured default VLAN I D fo r the VAP interface.

Note: When using IEEE 802.1X to dynamically assign VLAN IDs, the access point must

have 802.1X authentication enabled and a RADIUS server configured. Wireless clients must also support 802.1X client software.

WDS Settings

Each access point radio inte rface can be configured to oper at e i n a br i dge or repeater mode, which al low s i t to fo rward traffic directly to other acce ss point units. To set up br i dge links between access poi nt units, you must configure the W Irel es s Distribution System (WDS) forwarding table by specifying the wireless MAC address of all units to which you want to forw ar d tr affic. Up t o si x W D S br i dge or r epeater links can be specified fo r ea ch unit in the wireless bridge ne twork.

The Spanning Tree Protocol (STP) can be used to detect and disable network loops, and to provide backup links between bridges. This allows a wireless bridge to interact with other bridgi ng devices (that is, an STP-com pliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provi de b ac kup links which automatic al ly take o ver w hen a primary link goes down.

WDS Bridge – Up to six WDS bridg e or rep eater links (MAC addresses ) pe r r adio interface can be specified for each unit in the wireless bridge network. One unit only must be configured as the “root br id ge” in the wireless network. The root bridge is the unit connected to the main core of the wired LAN. Other bridges need to specify one “Parent” link to the root br id ge or to a bridge connected to th e ro ot bridge. The other five WDS links are avai labl e as “Child” links to other bridg es.

• Bridge Role – Each radio interface can be s et to op er at e in one of the following four modes: (Default: AP)

• AP (Access Point): Operates as an access point for wireless clients, providing

connectivity to a wired LAN.

6-21

System Configuration

• Bridge: Operates as a bridge to other access points. The “Parent” link to the root bridge must be configur ed. Up to five other ”Child” links ar e available to other bridges.

• R ep eater: Operates as a wireless repeater, extending th e range for remote wireless clients and connecting them to the root bridge. The “Parent” link to the root bridge must be conf ig ur ed. In th is mo de, traffic is not forwarded to the Ethernet port from the radio interf ace.

• Root Bridge: Operates as the root bridge in the wireless bridge network. Up to six ”Child” links are avai labl e to ot her br id ges in the network.

• Bridge Parent – The physical layer address of the root bridge unit or the bridge unit connected to the root bridge. (12 hexadecimal digits in the form “xx-xx-xx-xx-xx-xx”)

• Bridge Child – The physical layer address of other bridge units for which this unit serves as the bridge par ent or the roo t bridge. Note that the first entry under the list of child nodes is reserved for the root bridge, and can only be configured if the role is set to “Root Bridge.” (12 hexadecimal digits in the form “xx-xx-xx-xx-xx-xx”)

• Bridge Link Timer – Sets th e m ax imum time the bridge waits to recei ve a link message from the parent br id ge. (Range: 0 -100; Default: 0, tha t is disabled)

Child bridges periodically send requests for link information from the parent bridge.

The Parent bridge responds with the information and checks that it was received by the child bridge. The message includes link information on the connection path to the root bridge and conf irm s t hat the l in k is valid. If a link is detected as down , the bridge restarts the association process to try and recover the link.

Advanced Configuration

Spanning Tree Protocol – STP uses a distributed algorithm to select a bridging device (STP-compliant sw i t ch , br idge or router) that serves as the root of the spanning tree network. It se l ects a roo t po rt 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 connec te d to designated bridging devic es are assigned as

System Configuration

designated ports. After determining the lowest cost spanning tree, it enables all root ports and designated ports, an d di sables all other ports. Network pack ets ar e therefor e only forwarded between root ports and designated ports, eli m i nating any possible network loops.

Once a stable network topol ogy has been established, all brid ges listen for Hello BPDUs (Bridge Protocol Data Units) transmitted from the root bridge. If a bridge does not get a Hello BPDU after a pre def i ne d in t erv al (M aximum Age), the bridge assumes that the link to th e ro ot bridge is down. This bridge will the n i ni tia te negotiations with othe r bri dges to reconfigure the network to reestablish a valid network to pology.

• Bridge – Enables/disables STP on the wireless bridge or repeater. (Default: Disabled)

• Bridge 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 devic e. (Not e tha t low er numeric values indic at e higher priority.)

• R an ge: 0-65535

• D ef au l t: 32768

• Bridge Max Age – The maximum time (in seconds) a device can wait without receiving a configurati on m essage before attempt ing t o re configure. All device ports (except for design at ed ports) should receive configuration messag es at regular intervals. Any port tha t ages out STP i nf or m ati on ( pr ovi d ed i n th e last configuration message) becomes the designated port for the attached LAN. If it is a root port, a new root port is se le ct ed from among the device por t s at ta ch ed t o the network. (Range: 6-40 seconds)

• D ef au l t: 20

• M i nim um: The higher of 6 or [2 x (Hello Tim e + 1) ] .

• M aximum: The lower of 40 or [2 x (Fo rw ard D el ay - 1)]

• Bridge Hello Time – Interval (in seconds) at which the r oot device transmits a configuration message. (Range: 1-10 seconds)

• D ef au l t: 2

• Minimum: 1

• M aximum: The lower of 10 or [(Max . Message Age / 2) -1]

• Bridge Forwarding Delay – The maximum time (in seconds) this device waits before changing states ( i.e. , di sca rding 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 informa tion tha t wo ul d m ake it return to a discarding st at e; ot herwise, temporary data loops might result. (Range: 4-30 seconds)

• D ef au l t: 15

• M i nimum: The higher of 4 or [(Max. M essage Age / 2) + 1]

• Maximum: 30

• Link Pa th 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 w ith slo w er m edi a. (Path cost takes precedence over port priority.)

• R an ge: 1-65535

• D efault: Ethernet interface: 19 ; Wire l ess in te rface: 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., low est value) will be configured as an act iv e l ink i n th e 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 pri or ity , the port with lowest numeric ident i fie r w ill be enabled.

• D ef au l t: 128

• Range: 0-240, in steps of 16

CLI Commands for WDS Settings – To set the role of th e ac cess point radio interface, use the bridge role command from the CLI wireless interface configuration mode. If th e ro le of the rad io in terf ac e i s set t o “Br idge” or “Repeater,” the MAC address of the paren t no de must also be configure d us in g t he bridge-link parent command.

Changing the Password

Management acces s t o th e web and CLI interface on the ac cess point is controlled through a single user na m e and password. You can also gain additional access security by using contro l fi lter s ( see “Filter Control” on page 6-17) .

To protect access to the management interface , you need to confi gure an Administ r ator’s user name and password as soon as possible. If the user name and password are not configur ed, th en anyone having access to th e access point may be able to compromise access point and network security. Once a new Administrator has been configured, you can delete the default “admin” user name from the system.

Note: Pressing the Reset button on the back of the access point for more than five

seconds resets the user name and password to the factory defaults. For this reason, we recommend that you protect the access point from physical access by unauthorized persons.

Configuring SNTP

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 sys te m lo g to rec or d m eaningful dates and times for event entries. If the clock is not set, the access point will only record the time from the fac tory default set at the last bootup.

The access point acts as an SNTP client, periodically sending time synchronization requests to specific time s er ver s. You can configure up to two time server IP addresses. The access point will attempt to poll each server in the configured sequence.

SNTP Server – Configure s t he ac cess point to operate as an SNTP client. When enabled, at least one time ser ver IP address must be sp ecif i ed.

• Primary Server: The IP address of an SNTP or N TP t ime ser ver 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 fro m the sec ondary server.

6-35

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) base d on the time at the Earth’s prime merid ia n, zero degrees longitude. To display a time corresponding to your local time, you must indicate the number of hour s your time zone is located b ef or e (e ast ) or after (west) UTC.

Enable Daylight Saving – The access point provides a wa y t o aut om atically adjust the system clock for Dayl i ght Savings Time changes. To use this feature you must define the month and date to b egi n and to end the change from standard time. During this period the sys t em cl ock is set back by one hour.

CLI Commands for SNTP – To enable SNTP support on the access point, from the global configuration mode specify SNTP server IP addresses using the sntp-server ip command, then use the sntp-server enable command to enable the service. Use the sntp-server timezone command to set the time zone for your location, and th e sntp-server daylight-saving comma nd t o set daylight savings.

A defined set of variables, known as managed objects, is maintained by the SNM P agent and used to manage the device. These objects are defined in a Management Information Base (M I B) th at pr ovi de s 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.

System Configuration

The access point includes an onboard agent that supports SNMP versions 1, 2c, and 3 clients. This agent continuously monitors the status of the acc ess point, as well as the traffic passing to and from wirel es s cl i ents. A ne twork management station can access this inform at i on using SNMP manageme nt softw ar e th at is compliant with MIB II. To implement SNMP management, the access point must first have an IP address and subnet mask, configured ei t her m anually 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 communi ty st ring for authentication.

Access to th e acces s poi nt us ing SNMP v3 pr ovid es ad diti ona l sec urit y fea ture s that cover message integr i ty, authentication, and en cryption; as well as contro lli ng notifications that are sent to specified user targets.

Configuring SNMP and Trap Message Parameters

The access point SNMP agent must be enabled to funct ion (for versions 1, 2c, and 3 clients). Management acc ess using SNMP v1 and v2c als o re quires community strings to be configure d fo r au th entication. Trap notifications can be enabled and sent to up to four management stations.

SNMP

SNMP – Enables or disable s SN M P management access and also enables the access point to send SNM P traps (n ot ifications). (Default: Disable )

Location – A text strin g t hat describes the system location. (Maximum lengt h: 255 characters)

Contact – A text string that describe s t he system contact. (Maximum l ength: 255 characters)

Community Name (Read Only) – Defines the SNM P community access stri ng t hat has read-only access. A ut hor i ze d management stations are onl y able to retrieve MIB objects. (Maximum len gt h: 23 characters, case sensitive; Default: public)

Community Name (Read/Write) – Defines the SNMP community access string that has read/write access . Au th or iz ed ma nagement stations are able to bot h r et rieve and modify MIB objects. (Max imum length: 23 characters , case sensitive; Default: private)

Trap Destination (1 to 4) – Enables recipients (up to four) of SNMP notificat ions.

• Trap Destination IP Address – Specifies the recipient of SNMP notifications. Enter the IP address or the host name. (Host Name: 1 to 63 characters, case sensitive)

• Trap Destination Community Name – The community string sent with the notification operation. (Maximum length: 23 chara ct er s, case sensitive; Default: public)

Engine ID – Sets the engine identifier for the S N M Pv3 agent that resides on the access point. This engine protects against message replay, delay, and redirection. The engine ID is also used in combination with user passwords to generate the security keys for authen tic at ing and encrypting SNMPv3 pack ets. A def au l t en gine ID is automatically generated that is unique to the acc ess point. (Range: 10 to 64 hexadecimal char acters)

Note: If the local engine ID is deleted or changed, all SNMP users will be cleared. All

existing users will need to be re-configured. If you want to change the default engine ID, change it first before configuring other SNMP v3 parameters.

Configuring SNMPv3 Users

The access point allows up to 10 SN M P v3 users to be configured . Ea ch us er mu st be defined by a unique name, assi gned to one of three pre-defined security groups, and configured with spe ci f ic aut hentication and encryp tion settings.

User – The SNMPv3 user name. (3 2 ch ar act ers maximum) Group – The SNMPv3 group name. (Options: RO, RWAuth, or RWPriv; Default: RO)

• RO – Read-only access.

• RWAuth – Read/write acce ss wit h user authentication.

• RWPriv – Read/write access w ith both user authenticatio n an d dat a encryption. Auth Type – The authentication type used for the SNMP user; eithe r MD 5 or no ne.

When MD5 is selected, ent er a password in the correspondi ng Passphrase field. Priv Type – The data encryption type used for the SNMP user; either DES or none.

When DES is selected, en te r a ke y i n the corresponding Passphrase field.

6-42

SNMP

Passphrase – The password or key associated with the authentication and privacy settings. A minimum of eigh t plain text characters is require d.

Action – Click the Add button to add a new user to the list. Click the edit button to change details of an existing user. Click the Del button to remove a user from the list.

Note: Users must be assigned to groups that have the same security levels. For

example, a user who has “Auth Type” and “Priv Type” configured to MD5 and DES respectively (that it, uses both authentication and data encryption) must be assigned to the RWPriv group. If this same user were instead assigned to the read-only (RO) group, the user would not be able to access the database.

CLI Commands for Configuring SNMPv3 Users – Use the snmp-server engine-id command to define the SNM P v3 engine before assigni ng users to groups. Use the snmp-server user command to assign users to one of the three groups and set the appropriate authenti ca tion and encryption types to be used. To vie w th e current SNMP v3 engine ID, use the show snmp command. To view SNMP users and group settings, use the sh ow snm p users or show snmp group-assignments commands.

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 us er, IP address, and UDP port. A user-defi ned not i fic at io n filt er can be created so that specifi c notifications can be prev ent ed 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.

To conf igure a new notification filter, click the New button. A new page opens to configure the filter (see below). To edit an existing filter, select the radio button next to the entry in the table and then click th e Edit button. To delete a filter, select the radio button next to the entr y in t he tab le and t hen click the Delete button.

When you click on the New but t on in the SNMP Trap Filters page, a new page opens where the filter parameters are configured. Define a filter name, subtree ID to be filtered, and a mask if required. Select the filter type, include or exclude, from the drop-down list. Click Appl y t o cr eat e the filter.

To add more subtree IDs to the filter, return to th e SNMP Trap Filters page and click the Edit button. In the Edit page, click the New button to access the Add SNMP Notification Subtree page and configure a new subtree ID to be f iltered.

6-44

SNMP

Note: Only the New Filter page allows the Filter ID to be configured.

Filter ID – A user-defined name th at ident i fies th e fil t er. (Maximum lengt h: 32 characters)

Subtree OI D – Specifies MIB subtree to be filtered. The MIB subtree must be defined in the form “.1.3.6 . 1” and al ways start with a “.”.

Subtree Mask – A hexadecimal value with each bit masking the corresponding ID in the MIB subtree. A “1” in the mask indicates an exact match and a “0” indicates a “wild card.” For example, a mask value of 0xFFBF provides a bit mask “1111 1111 1011 111 1.” 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 th ere are more subtree IDs than bi ts in the mask, the mask is padded with ones.

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. By default all traps are sent, so yo u can first use an “include” filter entry f or all t rap obj ec ts. Then use “exclude” entries fo r t he required trap objects to send t o t he target . N ot e th at th e fil t er ent ries are applied in the sequence that they ar e d ef in ed.

Configuring SNMPv3 Targets

An SNMP v3 notification Target ID is specified by the SNMP v3 user, IP address, and UDP port. A user-defi ned filter can also be assigned t o specific targets to limit the notifications receive d t o specific MIB objects. (Note that th e filt er mu st firs t be configured. see “Confi gur i ng SNMPv3 Trap Filters” on page 6- 44)

To conf igure a new notification rec eiver targ et , clic k th e New button. A new page opens to configure the set tings (see below). To edit an existing target, select the radio button next to the entry i n t he tab le and t hen click the Edit button. To delete targets, select the radio button next to the entry in the table and then click the Delete button.

When you click on the New or Edit button in the SNMP Targets page, a new page opens where the target paramet er s ar e configured. Define the parameters and select a filter, if required. Note that the SNM P v3 u ser name must first be define d (see “Configuring SNMPv3 Users” on page 6-42). Click Apply.

SNMP

Note: The Target ID cannot be changed in the Edit Target page. Only the New Target

page allows the Target ID to be configured.

Ta rget I D – A user-defined name that identifies a receiver of no tific ati ons. The access point supports up to 10 target IDs. (Maximum leng th : 32 cha racters)

IP Address – Specifies the IP address of the receiving management station. UDP Port – The UDP port that is used on the re ceiving management station for

notification messages .

SNMP User – The defined SNMP v3 user that is to receive notificati on m essages. Assigned Filter – The name of a user - def i ned notification filter that is appli ed t o the

target.

CLI Commands for Configuring SNMPv3 Targets – To cr eat e a notification target, use the snmp-server targets command from the CLI conf igur at ion mod e. To assign a filter to a target, use the snmp-server filter-assignment command. To view the current SNMP targets, use the show sn mp target command from t he C LI Exec mode.

Radio Interface

The IEEE 802.11a and 802.11g interfaces include configuration optio ns for radio signal characteristic s and wireless security features. The configuration op tions are nearly id entical, and are therefore both covered in this secti on of the manual.

The access point can operate in three modes, IEEE 802.11a only , 802.11b/g only, or a mixed 802.11a/b/g mode. Also note that 802.11g is backward compatible w ith

802.11b. These interfaces are configured independently under the followi ng web pages:

• Radio Interface A: 802.11a

• Radio Interface G: 802.11b/g 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 segregated based on user groups or applicati on t ra ffic. Each VAP can have up to 64 wireless clients, whereby the cl ients associate with these VAPs the same as they would with a physical access point.

Note: The radio channel settings for the access point are limited by local regulations,

which determine the number of channels that are available. Refer to “General Specifications” on page C-1 for additional information on the maximum number channels available.
