THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL
STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT
SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE
OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Opening a TAC Case
The online TAC Case Open Tool (http://www.cisco.com/tac/caseopen) is the fastest way to open P3 and
P4 cases. (Your network is minimally impaired or you require product information). After you describe
your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution.
If your issue is not resolved using these recommendations, your case will be assigned to a Cisco TAC
engineer.
For P1 or P2 cases (your production network is down or severely degraded) or if you do not have Internet
access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2
cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is “down” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.

Overview
The Cisco Aironet 1300 Series Bridget (hereafter called the bridge) is a wireless device designed for
building-to-building wireless connectivity. Operating in the 2.4-GHz band (2.400 to 2.497 GHz), using
the IEEE 802.11g standard, the bridge delivers 1 to 54 Mbps data rates without the need for a license.
The bridge is a self-contained unit designed for outdoor installations, providing differing antenna gains
as well as coverage patterns. It supports point-to-point and multipoint bridging configurations. When
placed in access point mode, the bridge supports wireless IEEE 802.11b and

Power
The bridge receives inline power from the Cisco Aironet Power Injector (hereafter called the power
injector). Dual-coax cables are used to provide Ethernet data and power from the power injector to the
bridge. The power injector is an external unit designed for operation in a sheltered environment, such as
inside a building or vehicle. The power injector also functions as an Ethernet repeater by connecting to a
Category 5 LAN backbone and using the dual-coax cable interface to the bridge.
The power injector uses an external 48-VDC power module and injects the DC voltage into the dual-coax
cables to power the bridge. The power injector can be also directly connected to a +12 VDC to +48 VDC
power source, such as a vehicle battery.
Note
The power injector and the power module should not be placed in an outdoor unprotected environment or
in an environmental air space, such as above a suspended ceiling.
Integrated Antenna
The bridge is available with an integrated 13-dBi patch array antenna. The antenna is covered with a
radome to protect it from environmental elements. When configured with the integrated antenna, the
antenna polarization is controlled by the mounting orientation of the bridge.
Note
Some international regulatory regions may restrict the integrated antenna bridge configuration.
External Antenna
The bridge is available in an external antenna configuration (see Figure 1-1) for use with existing Cisco
Aironet 2.4-GHz antennas. Two reverse-TNC type RF connectors are provided on the end of the unit to
support single or diversity antenna configurations.
The antennas connect to the bridge antenna connectors using a coax cable. The list below contains some

Port Aggregation or Redundancy Configuration
The port aggregation or redundancy configuration (Figure 1-5) is used to provide increased bandwidth
or backup redundancy communications between two LANs. Port aggregation or increased bandwidth
occurs when both wireless links are used to simultaneously pass Ethernet traffic. Backup communication
redundancy can be achieved with this configuration when one wireless bridge link is used only if the
other wireless bridge link fails.

Safety Information
CISCO CO NFID ENTIA L - Fir s t Draft
Safety Information
Follow the guidelines in this section to ensure proper operation and safe use of the bridge.
FCC Safety Compliance Statement
The FCC, with its action in ET Docket 96-8, has adopted a safety standard for human exposure to RF
electromagnetic energy emitted by FCC-certified equipment. When used with approved Cisco Aironet
antennas, Cisco Aironet products meet the uncontrolled environmental limits found in OET-65 and ANSI
C95.1, 1991. Proper operation of this radio device according to the instructions in this publication results
in user exposure substantially below the FCC recommended limits.
Safety Precautions
Warning
Do not locate the antenna near overhead power lines or other electric light or power circuits, or
where it can come into contact with such circuits. When installing the antenna, take extreme care
not to come into contact with such circuits, as they may cause serious injury or death. For proper
installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.:NFPA 70,
National Electrical Code, Article 810, in Canada: Canadian Electrical Code, Section 54).
Each year hundreds of people are killed or injured when attempting to install an antenna. In many of
these cases, the victim was aware of the danger of electrocution, but did not take adequate steps to avoid
the hazard.
For your safety, and to help you achieve a good installation, please read and follow these safety
precautions. They may save your life!
1.
If you are installing an antenna for the first time, for your own safety as well as others, seek
professional assistance.
2.
Select your installation site with safety, as well as performance in mind. Remember: electric power
lines and phone lines look alike. For your safety, assume that any overhead line can kill you.
3.
Call your electric power company. Tell them your plans and ask them to come look at your proposed
installation. This is a small inconvenience considering your life is at stake.
4.
Plan your installation carefully and completely before you begin. Successful raising of a mast or
tower is largely a matter of coordination. Each person should be assigned to a specific task, and
should know what to do and when to do it. One person should be in charge of the operation to issue
instructions and watch for signs of trouble.
5.
When installing your antenna, remember:
a. Do not use a metal ladder.
b. Do not work on a wet or windy day.
c. Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or
jacket.
6.
If the assembly starts to drop, get away from it and let it fall. Remember, the antenna, mast, cable,
and metal guy wires are all excellent conductors of electrical current. Even the slightest touch of any
of these parts to a power line complete an electrical path through the antenna and the installer: you!

Installation Overview
Installation Guidelines
CISCO CO NFID ENTIA L - Fir s t Draft
Installation Guidelines
Because the bridge is a radio device, it is susceptible to common causes of interference that can reduce
throughput and range. Follow these basic guidelines to ensure the best possible performance:
•
Install the bridge in an area where structures, trees, or hills do not obstruct radio signals to and from
the bridge.
•
Install the bridge at a height sufficient to provide clear line-of-sight signal path.
Site Surveys
Every network application is a unique installation. Before installing multiple bridges, you should
perform a site survey to determine the optimum use of networking components and to maximize range,
coverage, and network performance.
Consider the following operating and environmental conditions when performing a site survey:
•
Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio
range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the
radio data increases.
•
Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio
range. As a general rule, range increases in proportion to antenna height. However, do not place the
antenna higher than necessary, because the extra height also increases potential interference from
other unlicensed radio systems.
•
Physical environment—Clear or open areas provide better radio range than closed or filled areas.
•
Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of
wireless devices. Avoid locating the devices in a location where there is an obstruction between the
sending and receiving antennas.
Unpacking the Bridge
Follow these steps to unpack the bridge:
Step 1
Open the shipping container and carefully remove the contents.
Step 2
Return all packing materials to the shipping container and save it.
Step 3
Ensure that all items listed in the “Package Contents” section are included in the shipment. If any item
is damaged or missing, notify your authorized Cisco sales representative.

CISCO CO NFID ENTIA L - Fir s t Draft
Bridge Bracket
The bridge bracket mounts on the back side of the bridge housing. The bracket mounts on four screw
posts on the unit. The support pins on the bridge bracket must be facing the sides of the unit. These
support pins are used to suspend the bridge in the notches on the mast mounting bracket until you secure
the mounting bolts.
The bridge brackets must be positioned to obtain the correct antenna polarization that matches the
remote antenna. The bridge housing contains an antenna polarization mark consisting of an arrow on the
side of the housing. When the bridge is positioned so that the arrow is pointing up, the bridge antenna is
vertically polarized. For horizontal polarization, the arrow should be pointing from left to right. All
bridges must use the same antenna polarization for best operation.
Mast Bracket
The mast bracket attaches to a mast or tower support and is used to secure the bridge.The procedure for
attaching the mounting bracket to the support depends on the pipe diameter, as shown in Table 3-1.

The startup and association sequence depends on the bridge configuration, which can be one of the
following types:
•
Default—The bridge attempts to associate with a root bridge for 60 seconds. If it does not associate
with a root bridge, it then attempts to associate with a non-root bridge.
•
Preconfigured—The bridge attempts to associate with a remote bridge in the configured mode,
either root or non-root. Because there are no timeouts, it is easier to align the antenna.
Aligning the Antenna Using RSSI LED Indications
You can align the integrated antenna using LEDs after the bridge successfully associates with a remote
bridge. In the installation mode before association to another bridge, the Install LED blinks amber. If the
bridge associates to a root bridge, the Install LED turns amber. If the bridge does not associate to a root
bridge in the first 60 seconds, the Install LED blinks green to indicate beacons are being transmitted and
the bridge is waiting for another non-root bridge to associate.
During the first 20 seconds after association, the bridge reads the receive signal strength indictor (RSSI)
levels and records the maximum level received. Once 20 seconds have elapsed, the Install LED turns
amber and the Ethernet, status, and radio LEDs then display the relative RSSI levels compared to the
maximum received. The RSSI LED indications are shown in Table 3-3).
Note
For the signal level (dBm), a smaller number represents a stronger signal because the signal level is given
as a negative value.

Stacking Bridges
Overview
CISCO CO NFID ENTIA L - Fir s t Draft
Overview
You can double the throughput, or create a standby link, by stacking two bridges. A stacked installation
consists of two bridge systems installed at the same physical location. For detailed mounting instructions
refer to the Cisco Aironet 1300 Series Wireless Bridge Mounting Instructions that shipped with your
bridge.
Note
To meet regulatory restrictions, the external antenna BR1300 configuration and the external antenna
must be professionally installed. The network administration or other IT professional responsible for
installing and configuring the unit is a suitable professional installer. Following installation, access to the
unit should be password protected by the network administrator to maintain regulatory compliance.
Choosing a Second Mounting Location
You can mount the second bridge system in the same general location as the first as long as you separate
the antennas by at least TBD ft (TBD m). For example, in a flat-roof installation you can separate the
bridges horizontally, roughly perpendicular to the line of signal propagation. In a tower installation, you
can separate the antennas vertically. During the activation process, you verify that the interference
between systems is acceptably low. Do not attempt to stack more than two bridges. Figure 4-1 identifies
the interference paths with stacked bridges.

Stacking Bridges
Verifying Isolation - TBD
CISCO CO NFID ENTIA L - Fir s t Draft
Step 1
Install the link 1 bridges (bridges A and C) normally, but leave room at each site to install the link 2
bridges (bridges B and C).
Step 2
Activate the link 1 bridges, align the antennas, and verify proper operation of the link.
Step 3
At each site location, choose a candidate location for the second bridge that is at least TBD ft (TBD m)
away from the first bridge. Separate the bridges as far as is practical from each other, keeping in mind
that the second antenna must have a clear path to the remote system.
Step 4
At each site location, temporarily install the second link 2 bridge, positioning the antenna toward the
intended location of the corresponding link 2 remote antenna.
Note
You can improve system isolation by using different polarizations for the two local antennas. For
example, if the link 1 system has vertical polarization, assemble the link 2 system for horizontal
polarization.
Verifying Isolation - TBD
Isolation measurements are valid only if the link 1 bridges are operating at maximum power. By default,
the bridge operates at maximum power.
To verify signal isolation, refer to Figure 4-1 as you follow these steps:
Step 1
Ensure that the link 1 bridges are operating at full power and bridge A is configured as the root bridge.
Step 2
At Site 1, measure the isolation between bridges A and B:
Step 3
Step 4
a.
Activate the link 2 bridge (bridge B) as a non-root bridge and let it associate to bridge A (the root
bridge).
b.
Observe the bridge LEDs and verify that the RSSI signal level is (–54 dBm to - 53 dBm) or less. If
the RSSI signal exceeds –54 dBm, move the bridge farther away and repeat this procedure.
c.
Slowly rotate the bridge B antenna a few degrees to the left and to the right and verify that the RSSI
signal level does not spike above -54 dBm. If the signal peaks above -54 dBm, move the bridge
farther away and repeat this step.
Go to the remote Site 2 location to measure the isolation between bridges A and D:
a.
Activate the link 2 bridge (bridge D) as a non-root bridge and let bridge D associate to bridge A (the
root bridge).
b.
Observe bridge D’s LEDs and align the bridge D antenna with bridge A so that the RSSI signal level is
maximized.
c.
When the antennas are fully aligned, if the RSSI signal level is greater than -54 dBm, the bridge sites
are very close. Reduce the output power on all bridges at both sites (bridges A, B, C, and D) to 12
dBm.
d.
If you are still unable to reduce the RSSI signal level to -54 dBm, change the polarization of the link
2 bridges (bridges B and D). For example; change the antenna polarization from vertical to
horizontal.
At Site 2, measure the isolation between bridge C and D by following these steps:
a.
Turn off bridge A for this measurement.

Step 5
b.
Activate the link 2 bridge (bridge D) as a non-root bridge and the link1 bridge (bridge C) as a root
bridge and let bridge D associate to bridge C.
c.
Observe bridge D’s LEDs and verify that the RSSI signal level is -54 dBm or less. If the signal level
exceeds -54 dBm, move the bridge farther away and repeat this step.
d.
Slowly rotate the antenna of bridge D a few degrees to the left and to the right and verify that the
RSSI signal level does not spike above -54 dBm. If the signal peaks above -54 dBm, move the bridge
farther away and repeat this step.
After you verify the isolation of the second bridge link, you must properly set the root and non-root
bridge settings for both links, align the link 2 bridge antennas, and verify proper link 2 operation.

Configuring the Bridge for the First Time
Before You Start
CISCO CO NFID ENTIA L - Fir s t Draft
Before You Start
Before you install the bridge, make sure you are using a computer connected to the same network as the
bridge, and obtain the following information:
•
From your network system administrator:
– A system name
– The case-sensitive wireless service set identifier (SSID) for your radio network
– If not connected to a DHCP server, a unique IP address for your bridge (such as 172.17.255.115)
– If the bridge is not on the same subnet as your PC, a default gateway address and subnet mask
– A Simple Network Management Protocol (SNMP) community name and the SNMP file
attribute (if SNMP is in use)
•
If you use IPSU to find or assign the bridge IP address, the MAC address from the label on the
bottom of the bridge (such as 00164625854c)
Resetting the Bridge to Default Settings
If you need to start over during the initial setup process, follow these steps to reset the bridge to factory
default settings using the power injector’s Mode button:
Step 1
Disconnect the power jack from the power injector.
Step 2
Press and hold the power injector’s MODE button while you reconnect the power jack.
Step 3
Hold the MODE button until the Status LED turns amber (approximately 1 to 3 seconds) and wait until
the bridge boots up (Status LED turns green). All bridge settings return to factory defaults.
You can also use the web-browser interface to reset the bridge to defaults. Follow these steps to return
to default settings using the web-browser interface:
Step 1
Open your Internet browser. You must use Microsoft Internet Explorer (version 5.x or later) or Netscape
Navigator (version 4.x).
Step 2

Configuring the Bridge for the First Time
Obtaining and Assigning an IP Address
CISCO CO NFID ENTIA L - Fir s t Draft
Note
If the bridge is configured with a static IP address, the IP address is not changed.
Obtaining and Assigning an IP Address
To browse to the bridge’s Express Setup page, you must either obtain or assign the bridge’s IP address
using one of the following methods:
•
Use default address 10.0.0.1 when you connect to the bridge locally. For detailed instructions, see
the “Connecting to the Bridge Locally” section on page 5-3.
•
Use a DHCP server (if available) to automatically assign an IP address. You can find the
DHCP-assigned IP address using one of the following methods:
– Provide your organization’s network administrator with your bridge’s Media Access Control
(MAC) address. Your network administrator will query the DHCP server using the MAC
address to identify the IP address. The bridge’s MAC address is on label attached to the bottom
of the bridge.
– Use the Cisco IP Setup Utility (IPSU) to identify the assigned address. You can also use IPSU
to assign an IP address to the bridge if it did not receive an IP address from the DHCP server.
IPSU runs on most Microsoft Windows operating systems: Windows 9x, 2000, Me, NT, and XP.
You can download IPSU from the Software Center on Cisco.com. For additional information
refer to the “Obtaining and Installing IPSU” section on page 5-10.
Connecting to the Bridge Locally
If you need to configure the bridge locally (without connecting the bridge’s power injector to a wired
LAN), you can connect a PC to the power injector’s Ethernet port using a Category 5 Ethernet cable. You
can use a local connection to the Ethernet port much as you would use a serial port connection.
Note
You do not need a special crossover cable to connect your PC to the bridge’s power injector; you
can use either a straight-through cable or a crossover cable.
If the bridge is configured with default values and not connected to a DHCP server or cannot obtain an
IP address, it defaults to IP address 10.0.0.1 and becomes a mini-DHCP server. In that capacity, the
bridge provides up to twenty IP addresses between 10.0.0.11 and 10.0.0.30 to an Ethernet-capable PC
connected to the power injector’s Ethernet port.
The mini-DHCP server feature is disabled automatically when you assign a static IP address to the
bridge.
Caution
When a bridge with default settings is connected on a wired LAN and does not receive an IP address
from a DHCP server, the bridge provides an IP address to any DHCP requests it receives.

Configuring the Bridge for the First Time
Assigning Basic Settings
CISCO CO NFID ENTIA L - Fir s t Draft
Follow these steps to connect to the bridge locally:
Step 1
Make sure that the PC you intend to use is configured to obtain an IP address automatically, or manually
assign it an IP address from 10.0.0.31 to 10.0.0.40. Connect your PC to the power injector using a
Category 5 Ethernet cable. You can use either a crossover cable or a straight-through cable.
Note
When you connect your PC to the bridge’s power injector or reconnect your PC to the wired
LAN, you might need to release and renew the IP address on the PC. On most PCs, you can
perform a release and renew by rebooting your PC or by entering ipconfig /release and ipconfig
/renew commands in a command prompt window. Consult your PC operating instructions for
detailed instructions.
Step 2
Power up the power injector.
Step 3
Follow the steps in the “Assigning Basic Settings” section on page 5-4. If you make a mistake and need
to start over, follow the steps in the “Resetting the Bridge to Default Settings” section on page 5-2.
Step 4
After configuring the bridge, remove the Ethernet cable from your PC and connect the power injector to
your wired LAN.
Assigning Basic Settings
After you determine or assign the bridge’s IP address, you can browse to the bridge’s Express Setup page
and perform an initial configuration. Follow these steps:
Step 1
Open your Internet browser. You must use Microsoft Internet Explorer (version 5.x or later) or Netscape
Navigator (version 4.x).

What To Do Next
CISCO CO NFID ENTIA L - Fir s t Draft
What To Do Next
After your bridge has basic settings, you need to complete your bridge’s configuration. You might need
to adjust the output power level and other network and security settings.
Output Power Level
Your bridge’s output power level might require adjustment under the following conditions:
•
The bridge’s output power level must be reduced when using the 15-dBi sector or the 21-dBi dish
antenna (refer to “Maximum Power Levels and Antenna Gains” section on page D-3).
•
When bridges are installed less than 328 ft (100 m) apart, you should reduce their output power to
avoid overloading the bridge’s receivers.
•
Your regulatory domain may limit the equivalent isotropic radiated power (EIRP) from the bridge’s
antenna (refer to “Maximum Power Levels and Antenna Gains” section on page D-3).
To configure your bridge’s output power level, refer to the Cisco IOS Software Configuration Guide for
Cisco Aironet Bridges.
Protecting Your Wireless LAN
To prevent unauthorized access to your network, you must configure security settings. Because the
bridge is a radio device, the bridge communicates beyond the physical boundaries of your building.
Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Bridges to configure security
features to protect your network from intruders:
•
Unique SSIDs that are not broadcast in the bridge beacon
•
WEP and additional WEP features, such as TKIP and broadcast key rotation
•
Dynamic WEP and EAP authentication
Using the IP Setup Utility
IPSU enables you to find the bridge’s IP address when it has been assigned by a DHCP server. You can
also use IPSU to set the bridge’s IP address and SSID if they have not been changed from the default
settings.
Note
IPSU can be used only on the following operating systems: Windows 95, 98, NT, 2000, ME, or XP.
The sections below explain how to install the utility, how to use it to find the bridge’s IP address, and
how to use it to set the IP address and the SSID.

Step 6
Click Set Parameters to change the bridge’s IP address and SSID settings.
Step 7
Click Exit to exit IPSU.
Assigning an IP Address Using the CLI
When you connect the bridge to the wired LAN, the bridge links to the network using a bridge virtual
interface (BVI) that it creates automatically. Instead of tracking separate IP addresses for the bridge’s
Ethernet and radio ports, the network uses the BVI.
When you assign an IP address to the bridge using the CLI, you must assign the address to the BVI.
Beginning in privileged EXEC mode, follow these steps to assign an IP address to the bridge’s BVI:
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
interface bvi1
Enter interface configuration mode for the BVI.
Step 3
ip address address
mask
Assign an IP address and address mask to the BVI. This step
automatically saves the running configuration to the startup
configuration.
Note
You lose your connection to the bridge when you assign
a new IP address to the BVI. If you need to continue
configuring the bridge, use the new IP address to open
another Telnet session to the bridge.
Using a Telnet Session to Access the CLI
Follow these steps to access the CLI using a Telnet session. These steps are for a PC running Microsoft
Windows with a Telnet terminal application. Check your PC operating instructions for detailed
instructions for your operating system.
Step 1
Select Start > Programs > Accessories > Telnet.
If Telnet is not listed in your Accessories menu, select Start > Run, type Telnet in the entry field, and
press Enter.
Step 2
When the Telnet window appears, click Connect and select Remote System.
Note
Step 3
In Windows 2000, the Telnet window does not contain drop-down menus. To start the Telnet
session in Windows 2000, type open followed by the bridge’s IP address.
In the Host Name field, type the bridge’s IP address and click Connect.

Using the Command-Line Interface
IOS Command Modes
CISCO CO NFID ENTIA L - Fir s t Draft
IOS Command Modes
The Cisco IOS user interface is divided into many different modes. The commands available to you
depend on which mode you are currently in. Enter a question mark (?) at the system prompt to obtain a
list of commands available for each command mode.
When you start a session on the access point, you begin in user mode, often called user EXEC mode.
Only a limited subset of the commands are available in user EXEC mode. For example, most of the user
EXEC commands are one-time commands, such as show commands, which show the current
configuration status, and clear commands, which clear counters or interfaces. The user EXEC
commands are not saved when the access point reboots.
To have access to all commands, you must enter privileged EXEC mode. Normally, you must enter a
password to enter privileged EXEC mode. From this mode, you must enter privileged EXEC mode
before you can enter the global configuration mode.
Using the configuration modes (global, interface, and line), you can make changes to the running
configuration. If you save the configuration, these commands are stored and used when the access point
reboots. To access the various configuration modes, you must start at global configuration mode. From
global configuration mode, you can enter interface configuration mode and line configuration mode.
Table 7-1 describes the main command modes, how to access each one, the prompt you see in that mode, and
how to exit the mode. The examples in the table use the host name ap.

Abbreviating Commands
You have to enter only enough characters for the access point to recognize the command as unique. This
example shows how to enter the show configuration privileged EXEC command:
ap# show conf
Using no and default Forms of Commands
Most configuration commands also have a no form. In general, use the no form to disable a feature or
function or reverse the action of a command. For example, the no shutdown interface configuration
command reverses the shutdown of an interface. Use the command without the keyword no to re-enable
a disabled feature or to enable a feature that is disabled by default.

Understanding CLI Messages
CISCO CO NFID ENTIA L - Fir s t Draft
Configuration commands can also have a default form. The default form of a command returns the
command setting to its default. Most commands are disabled by default, so the default form is the same
as the no form. However, some commands are enabled by default and have variables set to certain default
values. In these cases, the default command enables the command and sets variables to their default
values.

Searching and Filtering Output of show and more Commands
You can search and filter the output for show and more commands. This is useful when you need to sort
through large amounts of output or if you want to exclude output that you do not need to see.
To use this functionality, enter a show or more command followed by the pipe character (|), one of the
keywords begin, include, or exclude, and an expression that you want to search for or filter out:
command | {begin | include | exclude} regular-expression
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
are not displayed, but the lines that contain Output are displayed.
This example shows how to include in the output display only lines where the expression protocol
appears:

Accessing the CLI
You can open the access point’s CLI using Telnet or Secure Shell (SSH).
Opening the CLI with Telnet
Follow these steps to open the CLI with Telnet. These steps are for a PC running Microsoft Windows
with a Telnet terminal application. Check your PC operating instructions for detailed instructions for
your operating system.
Step 1
Select Start > Programs > Accessories > Telnet.
If Telnet is not listed in your Accessories menu, select Start > Run, type Telnet in the entry field, and
press Enter.
Step 2
When the Telnet window appears, click Connect and select Remote System.
Note
In Windows 2000, the Telnet window does not contain drop-down menus. To start the Telnet
session in Windows 2000, type open followed by the access point’s IP address.
Step 3
In the Host Name field, type the access point’s IP address and click Connect.
Step 4
At the username and password prompts, enter your administrator username and password. The default
username is Cisco, and the default password is Cisco. The default enable password is also Cisco.
Usernames and passwords are case-sensitive.
Opening the CLI with Secure Shell
Secure Shell Protocol is a protocol that provides a secure, remote connection to networking devices set
up to use it. Secure Shell (SSH) is a software package that provides secure login sessions by encrypting
the entire session. SSH features strong cryptographic authentication, strong encryption, and integrity
protection. For detailed information on SSH, visit the homepage of SSH Communications Security, Ltd.
at this URL:
http://www.ssh.com/
SSH provides more security for remote connections than Telnet by providing strong encryption when a
device is authenticated. See the Cisco IOS Software Configuration Guide for Cisco Aironet Bridges for
detailed instructions on setting up the access point for SSH access.

Description
Power Injector
When the power injector is powered up, it sends a constant discovery tone on the dual-coax cables to the
bridge. When the bridge is connected to the dual-coax cables, it returns the discovery tone to the power
injector. When the power injector detects the returned discovery tone, it applies +48 VDC to the
dual-coax cables to the bridge.
When power is applied to the bridge, the bridge activates the bootloader and begins the POST operations.
The bridge begins to load the IOS image when the Post operations are successfully completed. Upon
successfully loading the IOS image, the bridge initializes and tests the radio.
The power injector LED is shown in Figure 8-2.

Checking Power
You can verify the availability of power to the bridge by checking the power injector LED (see
Figure 8-2):
•
Power LED
– Green color indicates 48 VDC is available (see Figure 8-2).
– Off indicates 48 VDC is not available—verify that the power module is connected to the power
injector and to an AC receptacle and that AC power is available.
Checking Basic Configuration Settings
Mismatched basic settings are the most common causes of lost wireless connectivity. If the bridge does
not associate with a remote bridge, check the following areas.
SSID
To associate, all bridges must use the same SSID. The bridge installation mode SSID is autoinstall and
the normal mode default SSID is tsunami. You should verify that the SSID value shown on the Express
Setup page is the same for all bridges. You should also verify that the bridges are configured for the
proper network role; only one bridge can be configured as the root bridge.
Security Settings
Remote bridges attempting to authenticate to your bridge must support the same security options
configured in the bridge, such as WEP, EAP or LEAP, MAC address authentication, Message Integrity
Check (MIC), WEP key hashing, and 802.1X protocol versions.
If a non-root bridge is unable to authenticate to your root bridge, verify that the security settings are the
same as your bridge settings. For additional information, refer to the Cisco IOS Software Configuration
Guide for Cisco Aironet Bridges.
Antenna Alignment
If your non-root bridges are unable to associate to your root bridge, you should verify the basic
configuration settings on all bridges before attempting to verify bridge antenna alignment (refer to
“Configuring the Bridge for the First Time” section on page 5-1). If your basic configuration settings are
correct, you can verify antenna alignment by using the Install mode RSSI LED indications. For
additional information, refer to the “Aligning the Antenna Using RSSI LED Indications” section on
page 3-5.

Resetting to the Default Configuration - TBD
CISCO CO NFID ENTIA L - Fir s t Draft
For detailed alignment instructions, refer to the Cisco Aironet 1300 Series Wireless Bridge Mounting
Instructions that shipped with your bridge.
Note
To meet regulatory restrictions, the external antenna BR1300 configuration and the external antenna
must be professionally installed. The network administration or other IT professional responsible for
installing and configuring the unit is a suitable professional installer. Following installation, access to the
unit should be password protected by the network administrator to maintain regulatory compliance.
Resetting to the Default Configuration - TBD
If you forget the password that allows you to configure the bridge, you may need to completely reset the
configuration. You can use the serial console port on the power injector or the web-browser interface.

Operating Range - TBD
Each regulatory region limits the equivalent isotropic radiated power (EIRP) that can be supported
within their region. This restricts the bridge output power that can be used with the bridge antennas and
affects the resulting operating range of the bridge.
Table C-2 and Table C-3 provide the calculated maximum operating ranges for IEEE 802.11b and IEEE
801.11g data rates. The calculations are based on 99.965% link availability.
