Introduction

The SMC EliteConnect Universal 2.4GHz/5GHz Wireless
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:

• SMC2888W-S – Includes an integrated high-gain antenna for
the 802.11a radio and is designed to operate as a “Slave”
bridge in point-to-multipoint configurations, or provide a
high-speed point-to-point wireless link between two sites. The

802.11b/g radio requires an external antenna option.

• SMC2888W-M – Provides only external antenna options and
is designed to operate as the “Master” bridge in
point-to-multipoint configurations, supporting wireless bridge
connections to as many as 16 SMC2888W-S Slave units.

Each model is housed in a weatherproof enclosure for mounting
outdoors and includes its own brackets for attaching to a wall,
pole, radio mast, or tower structure. The unit is powered through
its Ethernet cable connection from a power injector module that is
installed indoors.

The wireless bridge system offers a fast, reliable, and
cost-effective solution for connectivity between remote Ethernet
wired LANs or to provide Internet access to an isolated site. The
system is also easy to install and operate, ideal for situations
where a wired link may be difficult or expensive to deploy. The
wireless bridge connection provides data rates of up to 108
Mbps.

Introduction

In addition, both wireless bridge models offer full network
management capabilities through an easy-to-use web interface, a
command-line interface, and support for Simple Network
Management Protocol (SNMP) tools.

Radio Characteristics – The IEEE 802.11a and 802.11g
standards use a radio modulation technique known as
Orthogonal Frequency Division Multiplexing (OFDM), and a
shared collision domain (CSMA/CA). The 802.11a standard
operates in the 5 GHz Unlicensed National Information
Infrastructure (UNII) band, and the 802.11g standard in the 2.4
GHz band.

IEEE 802.11g includes backward compatibility with the IEEE

802.11b standard. IEEE 802.11b also operates at 2.4 GHz, but
uses Direct Sequence Spread Spectrum (DSSS) and
Complementary Code Keying (CCK) modulation technology to
achieve a communication rate of up to 11 Mbps.

The wireless bridge provides a 54 Mbps half-duplex connection
for each active channel (up to 108 Mbps in turbo mode on the

802.11a interface).

Hardware Description

Integrated High-Gain Antenna

The SMC2888W-S wireless bridge includes an integrated
high-gain (17 dBi) flat-panel antenna for 5 GHz operation.

External Antenna Options

The SMC2888W-M Master bridge unit does not include an
integrated antenna, but provides various external antenna options
for both 5 GHz and 2.4 GHz operation. In a point-to-multipoint
configuration, an external high-gain omnidirectional, sector, or
high-gain panel antenna can be attached to communicate with
bridges spread over a wide area.

External antennas connect to the N-type RF connectors on the
wireless bridge using the provided coaxial cables.

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.

Note: The power injector module does not support Power over Ethernet

(PoE) based on the IEEE 802.3af standard. The wireless bridge
unit must always be powered on by being connected to the power
injector module.

1-5

Introduction

Power Injector Module

The wireless bridge receives power through its network cable
connection using power-over-Ethernet technology. A power
injector module is included in the wireless bridge package and
provides two RJ-45 Ethernet ports, one for connecting to the
wireless bridge (Output), and the other for connecting to a local
LAN switch (Input).

The Input port uses an MDI (i.e., internal straight-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 that provide MDI-X ports.
However, when connecting the access point to a workstation or
other device that does not have MDI-X ports, you must use
crossover twisted-pair cable.

The wireless bridge does not have a power switch. It is powered
on when its Ethernet port is connected to the power injector
module, and the power injector module is connected to an AC
power source. The power injector includes one LED indicator that
turns on when AC power is applied.

1-6

Hardware Description

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.

Receive Signal Strength Indicator (RSSI) BNC Connector

The RSSI connector provides an output voltage that is
proportional to the received radio signal strength. A DC voltmeter
can be connected this port to assist in aligning the antennas at
both ends of a wireless bridge link.

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. A grounding screw is provided for attaching a ground wire
to the unit.

Wall- and Pole-Mounting Bracket Kits

The wireless bridge includes bracket kits that can be used to
mount the bridge to a wall, pole, radio mast, or part of a tower
structure.

Chapter 2

Network Configuration

The Dual-band Outdoor Access Point / Bridge system provides
access point or 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. Alternatively, you can employ both
access point and bridging functions together, offering a flexible
and convenient wireless solution for many applications.

This chapter describes the role of wireless bridge in various
wireless network configurations.

Access Point Topologies

Wireless networks support a stand-alone wireless configuration
as well as an integrated configuration with 10/100 Mbps Ethernet
LANs.

Wireless network cards, adapters, and access points can be
configured as:

• Ad hoc for departmental, SOHO, or enterprise LANs

• Infrastructure for wireless LANs

• Infrastructure wireless LAN for roaming wireless PCs

2-1

Network Configuration

The 802.11b and 802.11g frequency band, which operates at

2.4 GHz, can easily encounter interference from other 2.4 GHz
devices, such as other 802.11b or g wireless devices, cordless
phones and microwave ovens. If you experience poor wireless
LAN performance, try the following measures:

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

• Increase the distance between neighboring access points

• Increase the channel separation of neighboring access points

(e.g., up to 3 channels of separation for 802.11b or up to 5
channels for 802.11g)

Ad Hoc Wireless LAN (no Access Point or Bridge)

An ad hoc wireless LAN consists of a group of computers, each
equipped with a wireless adapter, connected through radio
signals as an independent wireless LAN. Computers in a specific
ad hoc wireless LAN must therefore be configured to the same
radio channel.

Access Point Topologies

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. Each wireless PC in a BSS can connect to any
computer in its wireless group or access other computers or
network resources in the wired LAN infrastructure through the
access 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
signals through one or more access points.

A wireless infrastructure can be used for access to a central
database, or for connection between mobile workers, as shown in
the following figure.

Network Configuration

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.

The BSS ID is only set by the access point, never by its clients.
The clients only need to set the Service Set Identifier (SSID) that
identifies the service set provided by one or more access points.
The SSID can be manually configured by the clients, 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 configured to create
an Extended Service Set (ESS). By placing the access points so
that a continuous coverage area is created, wireless users within
this ESS can roam freely. All wireless network card adapters and
wireless access points within a specific ESS must be configured
with the same SSID.

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 16 WDS links can be
specified for a SMC2888W-M unit, which acts as the “Master” in
the wireless bridge network. SMC2888W-S Slave units support
only one WDS link, which must be to the network’s master unit.

The SMC2888W-M and SMC2888W-S support WDS bridge 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 options.

2-5

Network Configuration

Note: The external antennas offer longer range options using the 5 GHz

radio, which makes this interface more suitable for bridge links.

When using WDS on a radio band, only wireless bridge units can
associate to each other. Wireless clients can only associate with
the wireless bridge using a radio band set to access point mode.

Point-to-Point Configuration

Two SMC2888W-S bridges can form a wireless point-to-point link
using their 5 GHz (802.11a) integrated antennas.

Bridge Link Planning

The SMC 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. This chapter provides guidance and information for
planning your wireless bridge links.

Note: The planning and installation of the wireless bridge requires

professional personnel that are trained in the installation of radio
transmitting equipment. The user is responsible for compliance
with local regulations concerning items such as antenna power,
use of lightning arrestors, grounding, and radio mast or tower
construction. Therefore, it is recommended to consult a
professional contractor knowledgeable in local radio regulations
prior to equipment installation.

Radio Path Planning

Although the wireless bridge uses IEEE 802.11a radio
technology, which is capable of reducing the effect of multipath
signals due to obstructions, the wireless bridge link requires a
“radio line-of-sight” between the two antennas for optimum
performance.

The concept of radio line-of-sight involves the area along a radio
link path through which the bulk of the radio signal power travels.

3-1

Bridge Link Planning

This area is known as the first Fresnel Zone of the radio link. For
a radio link not to be affected by obstacles along its path, no
object, including the ground, must intrude within 60% of the first
Fresnel Zone.

The following figure illustrates the concept of a good radio
line-of-sight.

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.

When planning the radio path for a wireless bridge link, consider
these factors:

• Avoid any partial line-of-sight between the antennas.

• Be cautious of trees or other foliage that may be near the path,

or may grow and obstruct the path.

3-2

Radio Path Planning

• Be sure there is enough clearance from buildings and that no
building construction may eventually block the path.

• Check the topology of the land between the antennas using
topographical maps, aerial photos, or even satellite image
data (software packages are available that may include this
information for your area).

• Avoid a path that may incur temporary blockage due to the
movement of cars, trains, or aircraft.

Antenna Height

A reliable wireless link is usually best achieved by mounting the
antennas at each end high enough for a clear radio line of sight
between them. The minimum height required depends on the
distance of the link, obstacles that may be in the path, topology of
the terrain, and the curvature of the earth (for links over 3 miles).

For long-distance links, a mast or pole may need to be
contsructed to attain the minimum required height. Use the
following table to estimate the required minimum clearance above
the ground or path obstruction (for 5 GHz bridge links).

Note that to avoid any obstruction along the path, the height of
the object must be added to the minimum clearance required for a
clear radio line-of-sight. Consider the following simple example,
illustrated in the figure below.

Radio Path Planning

A wireless bridge link is deployed to connect building A to a
building B, which is located three miles (4.8 km) away. Mid-way
between the two buidings is a small tree-covered hill. From the
above table it can be seen that for a three-mile link, the object
clearance required at the mid-point is 5.3 m (17.4 ft). The
tree-tops on the hill are at an elevation of 17 m (56 ft), so the
antennas at each end of the link need to be at least 22.3 m (73 ft)
high. Building A is six stories high, or 20 m (66 ft), so a 2.3 m
(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.

Note: Local regulations may limit or prevent construction of a high radio

mast or tower. If your wireless bridge link requires a high radio
mast or tower, consult a professional contractor for advice.

Antenna Position and Orientation

Once the required antenna height has been determined, other
factors affecting the precise position of the wireless bridge must
be considered:

• Be sure there are no other radio antennas within 2 m (6 ft) of
the wireless bridge

• Place the wireless bridge away from power and telephone
lines

• Avoid placing the wireless bridge too close to any metallic
reflective surfaces, such as roof-installed air-conditioning
equipment, tinted windows, wire fences, or water pipes

3-5

Bridge Link Planning

• The wireless bridge antennas at both ends of the link must be
positioned with the same polarization direction, either
horizontal or vertical

Antenna Polarization — The wireless bridge’s integrated
antenna sends a radio signal that is polarized in a particular
direction. The antenna’s receive sensitivity is also higher for radio
signals that have the same polarization. To maximize the
performance of the wireless link, both antennas must be set to
the same polarization direction. The antenna polarization is
marked on the wireless bridge, as indicated in the following
figure.

V

H

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.

If radio interference is still a problem with your wireless bridge
link, changing the antenna polarization direction may improve the
situation.

3-6

Radio Path Planning

Weather Conditions

When planning wireless bridge links, you must take into account
any extreme weather conditions that are known to affect your
location. Consider these factors:

• Temperature — The wireless bridge is tested for normal
operation in temperatures from -33°C to 55°C. Operating in
temperatures outside of this range may cause the unit to fail.

• Wind Velocity — The wireless bridge can operate in winds up
to 90 MPH and survive higher wind speeds up to 125 MPH.
You must consider the known maximum wind velocity and
direction at the site and be sure that any supporting structure,
such as a pole, mast, or tower, is built to withstand this force.

• Lightning — The wireless bridge includes its own built-in
lightning protection. However, you should make sure that the
unit, any supporting structure, and cables are all properly
grounded. Additional protection using lightning rods, lightning
arrestors, or surge suppressors may also be employed.

• Rain — The wireless bridge is weatherproofed against rain.
Also, prolonged heavy rain has no significant effect on the
radio signal. However, it is recommended to apply
weatherproof sealing tape around the Ethernet port and
antenna connectors for extra protection. If moisture enters a
connector, it may cause a degradation in performance or even
a complete failure of the link.

• Snow and Ice — Falling snow, like rain, has no significant
effect on the radio signal. However, a build up of snow or ice
on antennas may cause the link to fail. In this case, the snow
or ice has to be cleared from the antennas to restore operation
of the link.

3-7

Bridge Link Planning

Ethernet Cabling

When a suitable antenna location has been determined, you must
plan a cable route form the wireless bridge outdoors to the power
injector module indoors. Consider these points:

• The Ethernet cable length should never be longer than 100 m
(328 ft)

• Determine a building entry point for the cable

• 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. Be
sure that grounding is available and that it meets local and
national electrical codes.

3-8

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. (See the section “Testing Basic Link Operation” in
this chapter.)

The wireless bridge includes its own bracket kit for mounting the
unit to a 1.5 to 2 inch diameter steel pole or tube. The
pole-mounting bracket allows the unit to be mounted to part of a
radio mast or tower structure. The unit also has a wall-mounting
bracket kit that enables it to be fixed to a building wall or roof
when using external antennas.

Hardware installation of the wireless bridge involves these steps:

1. Mount the unit on a wall, pole, mast, or tower using the
mounting bracket.

2. Mount external antennas on the same supporting structure

as the bridge and connect them to the bridge unit.

3. Connect the Ethernet cable and a grounding wire to the unit.

4. Connect the power injector to the Ethernet cable, a local LAN

switch, and an AC power source.

4-1

Hardware Installation

5. Align antennas at both ends of the link.

Testing Basic Link Operation

Set up the units over a very short range (15 to 25 feet), either
outdoors or indoors. Connect the units as indicated in this chapter
and be sure to perform all the basic configuration tasks outlined
above. When you are satisfied that the links are operating
correctly, proceed to mount the units in their intended locations.

Mount the Unit

Using the Pole-Mounting Bracket

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. Always attach the bracket to a pole with the open end of the
mounting grooves facing up.

2. Place the U-shaped part of the bracket around the pole and

tighten the securing nut just enough to hold the bracket to the
pole. (The bracket may need to be rotated around the pole
during the alignment process.)

Mounting on Larger Diameter Poles

In addition, there is a method for attaching the pole-mounting
bracket to a pole that is 2 to 5 inches in diameter using an
adjustable steel band clamp (not included in the kit). A steel band
clamp up to 0.5 inch (1.27 cm) wide can be threaded through the
main part of the bracket to secure it to a larger diameter pole
without using the U-shaped part of the bracket. This method is
illustrated in the following figure.

Steel Band Clamp

Using the Wall-Mounting Bracket

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 an external antenna.

1. Always attach the bracket to a wall with the open end of the
mounting grooves facing up (see following figure).

2. Position the bracket in the intended location and mark the
position of the three mounting screw holes.

3. Drill three holes in the wall that match the screws and wall
plugs included in the bracket kit, then secure the bracket to
the wall.

4. Use the included nuts to tightly secure the wireless bridge to
the bracket.

Connect External Antennas

When deploying a SMC2888W-M Master bridge 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. SMC2888W-S Slave units also require an external
antenna for 2.4 GHz operation.

Perform these steps:

1. Mount the external antenna to the same supporting structure

as the bridge, within 3 m (10 ft) distance, using the bracket
supplied in the antenna package.

4-5

Hardware Installation

2. Connect the antenna to the bridge’s N-type connector.

3. Apply weatherproofing tape to the antenna connectors to

help prevent water entering the connectors.

Note: The Ethernet cable included with the package is 30 m (100 ft)

long. To wire a longer cable (maximum 100 m, 325 ft), use the
connector pinout information in Appendix B.

2. For extra protection against rain or moisture, apply
weatherproofing tape (not included) around the Ethernet
connector.

3. Be sure to ground the unit with an appropriate grounding wire
(not included) by attaching it to the grounding screw on the

Hardware Installation

Note: The wireless bridge’s Ethernet port does not support Power over

Ethernet (PoE) based on the IEEE 802.3af standard. Do not try to
power the unit by connecting it directly to a network switch that
provides IEEE 802.3af PoE. Always connect the unit to the
included power injector module.

1. Connect the Ethernet cable from the wireless bridge to the
RJ-45 port labeled “Output” on the power injector.

2. Connect a straight-through unshielded twisted-pair (UTP)

cable from a local LAN switch to the RJ-45 port labeled
“Input” on the power injector. Use Category 5 or better UTP
cable for 10/100BASE-TX connections.

Note: The RJ-45 port on the power injector is an MDI port. If connecting

directly to a computer for testing the link, use a crossover cable.

5. Check the LED on top of the power injector to be sure that
power is being supplied to the wireless bridge through the
Ethernet connection.

Align Antennas

After wireless bridge units have been mounted, connected, and
their radios are operating, the antennas must be accurately
aligned to ensure optimum performance on the bridge links. This
alignment process is particularly important for long-range
point-to-point links. In a point-to-multipoint configuration the
Master bridge uses an omnidirectional or sector antenna, which
does not require alignment, but Slave bridges still need to be
correctly aligned with the Master bridge antennna.

• Point-to-Point Configurations – In a point-to-point
configuration, the alignment process requires two people at
each end of the link. The use of cell phones or two-way radio
communication may help with coordination. To start, you can
just point the antennas at each other, using binoculars or a
compass to set the general direction. For accurate alignment,
you must connect a DC voltmeter to the RSSI connector on
the wireless bridge and monitor the voltage as the antenna
moves horizontally and vertically.

• Point-to-Multipoint Configurations – In a point-to-multipoint
configuration all Slave bridges must be aligned with the
Master bridge antenna. The alignment process is the same as
in point-to-point links, but only the Slave end of the link
requires the alignment.

The RSSI connector provides an output voltage between 0 and

3.28 VDC that is proportional to the received radio signal
strength. The higher the voltage reading, the stronger the signal.
The radio signal from the remote antenna can be seen to have a

strong central main lobe and smaller side lobes. The object of the
alignment process is to set the antenna so that it is receiving the
strongest signal from the central main lobe.

To align the antennas in the link using the RSSI output voltage,
start with one antenna fixed and then perform the following

Note: The RSSI output can be configured through management

interfaces to output a value for specific WDS ports. See page
6-54 for more information.

1. Remove the RSSI connector cover and connect a voltmeter
using a cable with a male BNC connector (not included).

2. Pan the antenna horizontally back and forth while checking
the RSSI voltage. 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.

3. Find the point where the signal is strongest (highest voltage)
and secure the horizontal adjustment in that position.

Note: Sometimes there may not be a central lobe peak in the voltage

because vertical alignment is too far off; only two similar peaks for
the side lobes are detected. In this case, fix the antenna so that it
is halfway between the two peaks.

4. Loosen the vertical adjustment on the mounting bracket and
tilt the antenna slowly up and down while checking the RSSI
voltage.

5. Find the point where the signal is strongest and secure the
vertical adjustment in that position.

6. Remove the voltmeter cable and replace the RSSI connector
cover.

Chapter 5

Initial Configuration

The wireless bridge offers a variety of management options,
including a web-based interface, a command line interface (CLI),
or using SNMP management software.

Most initial configuration steps can be made through the web
browser interface using the Setup Wizard (page 5-4). However,
for units that do not have a preset country code, you must first set
the country code using the CLI.

Note: Units sold in some countries are not configured with a specific

country code. You must use the CLI to set the country code and
enable wireless operation (page 5-2).

The wireless bridge requests an IP address via DHCP by default.
If no response is received from a DHCP server, then the wireless
bridge uses the default address 192.168.2.2. If this address is not
compatible with your network, you can first perform initial
configuration using a PC that has IP settings compatible with this
subnet (for example, 192.168.2.3) and connecting it directly to the
wireless bridge. When the basic configuration is completed, you
can set new IP settings for the wireless bridge before connecting
it to your network.

5-1

Initial Configuration

Initial Setup through the CLI

The wireless bridge provides access to the CLI through a Telnet
connection. You can open a Telnet session by performing these
steps:

1. From the host computer, enter the Telnet command and the IP
address of the wireless bridge unit (default 192.168.2.2 if not
set via DHCP).

2. At the prompt, enter “admin” for the user name.

3. The default password is “smcadmin”.

The CLI will display the “Dual Outdoor#” prompt to show that you
are using executive access mode (i.e., Exec).

Username: admin
Password:
Dual Outdoor#

For a full 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 7-9.

Initial Configuration Steps

Setting the Country Code – Regulations for wireless products

differ from country to country. Setting the country code restricts
the wireless bridge to use only the radio channels and power
settings permitted in the specified country of operation. If the
wireless bridge unit is shipped with a preset country code, you
are not permitted to change it, as required by country regulations.
If the unit is set to the default “99,” you must set the country code
to the country of operation.

5-2

Initial Setup through the CLI

At the Exec prompt, type “country ?” to display the list of country
codes. Check the code for your country, then enter the country
command again followed by your country code (e.g., IE for
Ireland).

Dual Outdoor#country ie
Dual Outdoor#

Setting the IP Address – By default, the wireless bridge is
configured to obtain IP address settings from a DHCP server. You
may also use the CLI to assign an IP address that is compatible
with your network.

Type “configure” to enter configuration mode, then type “interface
ethernet” to access the Ethernet interface-configuration mode.

Dual Outdoor#configure
Dual Outdoor(config)#interface ethernet
Dual Outdoor(config-if)#

First type “no ip dhcp” to disable DHCP client mode. Then type “ip
address ip-address netmask gateway,” where “ip-address” is the
wireless bridge’s IP address, “netmask” is the network mask for
the network, and “gateway” is the default gateway router. Check
with your system administrator to obtain an IP address that is
compatible with your network.

Dual Outdoor(if-ethernet)#no ip dhcp

3. IP Configuration – Either enable or disable (Dynamic Host
Configuration Protocol (DHCP) for automatic IP configuration.
If you disable DHCP, then manually enter the IP address and
subnet mask. If a management station exists on another
network segment, then you must enter the IP address for a
gateway that can route traffic between these segments. Then
enter the IP address for the primary and secondary Domain
Name Servers (DNS) servers to be used for host-name to IP
address resolution.

• DHCP Client – With DHCP Client enabled, the IP
address, subnet mask and default gateway can be
dynamically assigned to the access point by the network
DHCP server. (Default: Enable)

Note: If there is no DHCP server on your network, then the access point

will automatically start up with its default IP address, 192.168.2.2.

5-8

TCP / IP Settings

Configuring the wireless bridge with an IP address expands your
ability to manage the wireless bridge. A number of wireless
bridge features depend on IP addressing to operate.

Note: You can use the web browser interface to access IP addressing

only if the wireless bridge already has an IP address that is
reachable through your network.

By default, the wireless bridge 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 (page 5-2). After you have network access to the
wireless bridge, you can use the web browser interface to modify
the initial IP configuration, if needed.

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

wireless bridge will automatically start up with a default IP address
of 192.168.2.2.

6-7

System Configuration

DHCP Client (Enable) – Select this option to obtain the IP

settings for the wireless bridge from a DHCP (Dynamic Host
Configuration Protocol) server. The IP address, subnet mask,
default gateway, and Domain Name Server (DNS) address are
dynamically assigned to the wireless bridge by the network
DHCP server.
(Default: Enabled)

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

• IP Address: The IP address of the wireless bridge. Valid IP

addresses consist of four decimal numbers, 0 to 255,
separated by periods.

• Subnet Mask: The mask that identifies the host address bits

used for routing to specific subnets.

6-8

Advanced Configuration

• Default Gateway: The default gateway is the IP address of the
router for the wireless bridge, which is used if the requested
destination address is not on the local subnet.

• If you have management stations, DNS, 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).

• 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 interface ethernet command. Use the 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 the Exec mode to

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. A secondary RADIUS
server may also be specified as a backup should the primary
server fail or become inaccessible.

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
documentation provided with the RADIUS server software.

6-10

Advanced Configuration

Primary Radius Server Setup – Configure the following settings

to use RADIUS authentication on the access point.

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

• Port: The UDP port number used by the RADIUS server for
authentication messages. (Range: 1024-65535;
Default: 1812)

6-11

System Configuration

• Key: A shared text string used to encrypt messages between
the access point and the RADIUS server. Be sure that the
same text string is specified on the RADIUS server. Do not
use blank spaces in the string. (Maximum length: 255
characters)

• 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)

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 primary server
fails. The access point uses the secondary server if the primary
server fails or becomes inaccessible. Once the access point
switches over to the secondary server, it periodically attempts to
establish communication again with primary server. If
communication with the primary server is re-established, the
secondary server reverts to a backup role.

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

PPPoE Settings

The wireless bridge uses a Point-to-Point Protocol over Ethernet
(PPPoE) connection, or tunnel, only for management traffic
between the wireless bridge and a remote PPPoE server
(typically at an ISP). Examples of management traffic that may
initiated by the wireless bridge and carried over a PPPoE tunnel
are RADIUS, Syslog, or DHCP traffic.

6-13

System Configuration

PPP over Ethernet – Enable PPPoE on the RJ-45 Ethernet

interface to pass management traffic between the unit and a
remote PPPoE server. (Default: Disable)

PPPoE Username – The user name assigned for the PPPoE
tunnel. (Range: 1-63 alphanumeric characters)

PPPoE Password – The password assigned for the PPPoE
tunnel. (Range: 1-63 alphanumeric characters)

Confirm Password – Use this field to confirm the PPPoE
password.

PPPoE Service Name – The service name assigned for the
PPPoE tunnel. The service name is normally optional, but may be
required by some service providers. (Range: 1-63 alphanumeric
characters)

6-14

Advanced Configuration

IP Allocation Mode – This field specifies how IP adresses for the

PPPoE tunnel are configured on the RJ-45 interface. The
allocation mode depends on the type of service provided by the
PPPoE server. If automatic mode is selected, DHCP is used to
allocate the IP addresses for the PPPoE connection. If static
addresses have been assigned to you by the service provider,
you must manually enter the assigned addresses. (Default:
Automatic)

• Automatically allocated: IP addresses are dynamically
assigned by the service provider during PPPoE session
initialization.

• Static assigned: Fixed addresses are assigned by the service
provider for both the local and remote IP addresses.

Local IP Address – IP address of the local end of the PPPoE
tunnel. (Must be entered for static IP allocation mode.)

Remote IP Address – IP address of the remote end of the PPPoE
tunnel. (Must be entered for static IP allocation mode.)

CLI Commands for PPPoE – From the CLI configuration mode,
use the interface ethernet command to access interface
configuration mode. Use the ip pppoe command to enable
PPPoE on the Ethernet interface. Use the other PPPoE
commands shown in the example below to set a user name and
password, IP settings, and other PPPoE parameters as required
by the service provider. The pppoe restart command can then
be used to start a new connection using the modified settings. To
display the current PPPoE settings, use the show pppoe
command from the Exec mode.

Authentication

Wireless clients can be authenticated for network access by
checking their MAC address against the local database
configured on the access point, or by using a database
configured on a central RADIUS server. Alternatively,
authentication can be implemented using the IEEE 802.1X
network access control protocol.

The access point can also operate in a 802.1X supplicant mode.
This enables the access point itself and any bridge-connected
units to be authenticated with a RADIUS server using a
configured MD5 user name and password. This mechanism can
prevent rogue access points from gaining access to the network.

6-16

Advanced Configuration

Ethernet Supplicant Setup – Allows the access point to act as an

802.1X supplicant so it can be authenticated through its Ethernet

port with a RADIUS server on the local network. When enabled, a
unique MD5 user name and password needs to be configured.
(Default: Disabled)

• Enabled/Disabled – Enables/Disables the 802.1X supplicant
function.

• Username – Specifies the MD5 user name. (Range: 1-22

characters)

• Password – Specifies the MD5 password. (Range: 1-22

characters)

WDS Supplicant Setup – Allows the access point to act as an

802.1X supplicant so it can be authenticated through a WDS

(wireless) port with a RADIUS server on the remote network.
When enabled, a unique MD5 user name and password needs to
be configured for the WDS port. For a SMC2888W-S Slave unit,
there is only one WDS port. For a SMC2888W-M Master unit,
there are 16 WDS ports. (Default: Disabled)

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: Local
MAC)

• Local MAC: The MAC address of the associating station is
compared against the local database stored on the access
point. The Local MAC Authentication section enables the local
database to be set up.

• Radius MAC: The MAC address of the associating station is
sent to a configured RADIUS server for authentication. When
using a RADIUS authentication server for MAC address
authentication, the server must first be configured in the
Radius window (page 6-10).

• Disable: No checks are performed on an associating station’s
MAC address.

6-18

Advanced Configuration

Note: Client station MAC authentication occurs prior to the IEEE 802.1X

authentication procedure configured for the access point.
However, a client’s MAC address provides relatively weak user
authentication, since MAC addresses can be easily captured and
used by another station to break into the network. Using 802.1X
provides more robust user authentication using user names and
passwords or digital certificates. So, although you can configure
the access point to use MAC address and 802.1X authentication
together, it is better to choose one or the other, as appropriate.

802.1X Setup – IEEE 802.1X is a standard framework for network
access control that uses a central RADIUS server for user
authentication. This control feature prevents unauthorized access
to the network by requiring an 802.1X client application to submit
user credentials for authentication. The 802.1X standard uses the
Extensible Authentication Protocol (EAP) to pass user credentials
(either digital certificates, user names and passwords, or other)
from the client to the RADIUS server. Client authentication is then
verified on the RADIUS server before the access point grants
client access to the network.

The 802.1X EAP packets are also used to pass dynamic unicast
session keys and static broadcast keys to wireless clients.
Session keys are unique to each client and are used to encrypt
and correlate traffic passing between a specific client and the
access point. You can also enable broadcast key rotation, so the
access point provides a dynamic broadcast key and changes it at
a specified interval.

You can enable 802.1X as optionally supported or as required to
enhance the security of the wireless network.

• Disable: The access point does not support 802.1X
authentication for any wireless client. After successful
wireless association with the access point, each client is
allowed to access the network.

6-19

System Configuration

• Supported: The access point supports 802.1X authentication
only for clients initiating the 802.1X authentication process
(i.e., the access point does not initiate 802.1X authentication).
For clients initiating 802.1X, only those successfully
authenticated are allowed to access the network. For those
clients not initiating 802.1X, access to the network is allowed
after successful wireless association with the access point.

• Required: The access point enforces 802.1X authentication
for all associated wireless clients. If 802.1X authentication is
not initiated by a client, the access point will initiate
authentication. Only those clients successfully authenticated
with 802.1X are allowed to access the network.

When 802.1X is enabled, the broadcast and session key rotation
intervals can also be configured.

• Broadcast Key Refresh Rate: Sets the interval at which the
broadcast keys are refreshed for stations using 802.1X
dynamic keying. (Range: 0-1440 minutes; Default: 0 means
disabled)

• Session Key Refresh Rate: The interval at which the access
point refreshes unicast session keys for associated clients.
(Range: 0-1440 minutes; Default: 0 means disabled)

• 802.1X Re-authentication Refresh Rate: The time period after
which a connected client must be re-authenticated. During the
re-authentication process of verifying the client’s credentials
on the RADIUS server, the client remains connected the
network. Only if re-authentication fails is network access
blocked. (Range: 0-65535 seconds; Default: 0 means
disabled)

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).

• Deny: Blocks access for all MAC addresses except those

listed in the local database as “Allow.”

• Allow: Permits access for all MAC addresses except

those listed in the local database as “Deny.”

• MAC Authentication Settings: Enters specified MAC
addresses and permissions into the local MAC database.

• MAC Address: Physical address of a client. Enter six pairs

of hexadecimal digits separated by hyphens; for example,
00-90-D1-12-AB-89.

System Configuration

• Permission: Select Allow to permit access or Deny to
block access. If Delete is selected, the specified MAC
address entry is removed from the database.

• Update: Enters the specified MAC address and
permission setting into the local database.

• MAC Authentication Table: Displays current entries in the local
MAC database.
