Introduction
CISCO CONFIDENTIAL -- Fir st Draft
Introduction
The Cisco Aironet 1400 Series Bridge (hereafter called the bridge) is a wireless device designed for
building to building wireless connectivity. Operating in the 5.8 GHz UNII 3 band (5725 to 5825 MHz),
derived from the 802.11a standard, the bridge delivers 6-54 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 and supports both point-to-point and multipoint
configurations.
The bridge uses a browser-based management system, but you can also configure the bridge using the
command-line interface (CLI) through a Telnet session, Cisco IOS commands, or Simple Network
Management Protocol (SNMP).
System Requirements
Cisco IOS Release 12.2(11)JA is factory installed on your bridge. As new Cisco IOS releases become
available for the bridge, you should consider upgrading to the latest release.
Determining the Software Version
To determine the version of IOS running on your bridge, use a Telnet session to log into the bridge and
enter the show version EXEC command. This example shows command output from a bridge running
Cisco IOS Release 12.2(11)JA:

CISCO CONFIDENTIAL -- Fir st Draft
New Features
Cisco IOS Release 12.2(11)JA
This section lists new features in Cisco IOS Release 12.2(11)JA for the bridge.
•
Antenna Alignment Assistance
– This feature provides a wireless bridge with an auto-configuration and installation mode for
out-of-box deployment of point-to-point links without requiring configuration via telnet, file
transfer protocol (FTP), or Simple Network Management Protocol (SNMP). This mode drives
LEDs and a received signal strength indicator (RSSI) port with a voltage output proportional to
the received signal strength for use during the installation and alignment process. This allows a
wireless bridge installation team without knowledge of Cisco IOS software or data networking
to install and verify the quality of the wireless link.
•
Wireless Programmable Clear Channel Assessment
– With the programmable clear channel assessment feature, wireless bridges can be configured to
a particular background interference level found in a specific environment for reduced overhead
contention with other wireless systems.
•
Wireless Root Bridge
– A wireless bridge connected to the main LAN network can be configured as a wireless root
bridge to provide support for point-to-point or point-to-multipoint bridging.
•
Wireless non-root bridge
– A wireless bridge connected to a remote LAN network can be configured as a wireless non-root
bridge to allow operation as the remote node in a point-to-point or point-to-multipoint network.
•
Wireless packet concatenation
– Wireless packet concatenation is the ability to concatenate smaller packets into larger ones to
more efficiently utilize the wireless medium and provide higher overall data throughputs on a
wireless bridge.
•
Wireless link distance adjustment
– The wireless link distance adjustment parameter allows you to tune the carrier sense multiple
access with collision avoidance (CSMA/CA) parameters for a particular range to maximize the
performance of a wireless bridge.
The following features in Cisco IOS Release 12.2(11)JA are not supported by the bridge:
•
Broadcast key rotation
•
Hot standby
•
Multiple service set identifiers (SSIDs)
•

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!
7.
If any part of the antenna system should come in contact with a power line, don’t touch it or try to
remove it yourself. Call your local power company. They will remove it safely.
If an accident should occur with the power lines call for qualified emergency help immediately.

Important Notes
CISCO CONFIDENTIAL -- Fir st Draft
Bridge Installation
The bridge is available in two configurations:
Note
•
Integrated antenna bridge (with 22.5 dBi directional antenna)
•
External antenna bridge (with antenna connector for use with an external antenna)
To meet regulatory restrictions, the external antenna bridge configuration and the external antenna must
be professional installed.
Personnel installing the bridge must understand wireless bridging techniques, antenna alignment and
adjustment, and grounding methods. The integrated antenna configuration can be installed by an
experienced IT professional.
Stacking Bridges
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 1400 Series Wireless Bridge Mounting Instructions that shipped with your
bridge.
Note
The bridge antennas must be separated by a minimum of 6.56 ft (2 m) from each other and from other
co-located antennas.
Important Notes
This section describes important information about the bridge.
Cisco Aironet Software Requires Completion of Encryption Authorization Form
In order to access Cisco Aironet software from the Software Center on Cisco.com, you must now fill out
a form to receive authorization to download encrypted software. Registered Cisco.com users are required
to fill out the form only once, while public users must do so once each session, each time software is
downloaded. A form is automatically created for public users. The form for Registered Cisco.com users
is located at the following URL:
http://www.cisco.com/cgi-bin/Software/Crypto/crypto_main.pl
Default Encryption Key 2 is Set by Bridge
The encryption key in slot 2 is the transmit key by default. If you enable WEP with MIC, use the same
WEP key as the transmit key in the same key slot on both root and non-root bridges.

Caveats
CISCO CONFIDENTIAL -- Fir st Draft
Limitation to PAgP Redundancy on Switches Connected by Bridge Links
When two switches configured for Port aggregation protocol (PAgP) are connected by redundant
wireless bridge links, the PAgP switchover time takes at least 30 seconds, which is too slow to maintain
TCP sessions from one port to another.
Power Client n CLI Command is not Supported
The bridge does not support the power client n command in the browser or CLI interfaces.
bridge(config-if)# power client n
(where n is a value of 13, 16, 19, 22, 23, 24, or maximum)
The bridge does not perform any action if this command is used.
Cannot Pass IP Traffic When Bridge # Route IP is Configured
The bridge # route IP command must not be configured for the bridge groups assigned to non-native
VLANS, because this setting stops IP traffic across the bridge for those non-native VLANS
Default Infrastructure SSID
When VLAN is enabled, the WEP encryption mode and the WEP key are applicable only to a native VLAN.
Any SSID configured should have the Infrastructure-SSID parameter enabled for that SSID. With the
Infrastructure-SSID parameter enabled, the bridge ensures that a non-native VLAN cannot be assigned
to that SSID.
ARP Table is Corrupted When Multiple BVIs are Configured
The bridge only supports one bridge virtual interface (BVI). Multiple BVIs should not be configured,
because this may cause the ARP table to become corrupted.
Caveats
This section lists open and resolved caveats in Cisco IOS Release 12.2(11)JA.
Open Caveats
These caveats are open in Cisco IOS Release 12.2(11)JA for the bridge:
•
CSCea08308—Default Infrastructure SSID.
When VLAN is enabled, the WEP encryption mode and the WEP key are applicable only to a native
VLAN. Any SSID configured should have the Infrastructure-SSID parameter enabled for that SSID.
With the Infrastructure-SSID parameter enabled, the bridge ensures that a non-native VLAN cannot
be assigned to that SSID.

•
CSCea46874—Limitation to PAgP Redundancy on Switches Connected by Bridge Links.
When two switches configured for Port aggregation protocol (PAgP) are connected by redundant
wireless bridge links, the PAgP switchover time takes at least 30 seconds, which is too slow to
maintain TCP sessions from one port to another.
•
CSCea57649—The CLI Help command produces incorrect output for the radio interface.
When using the CLI Help command from the radio interface, the command output is repeated
multiple times.
•
CSCea66380—Default Encryption Key 2 is Set by Bridge.
The encryption key in slot 2 is the transmit key by default. If you enable WEP with MIC, use the
same WEP key as the transmit key in the same key slot on both root and non-root bridges.
•
CSCea70652—Power Client n CLI Command is not Supported.
The bridge does not support the power client n command in the browser or CLI interfaces.
bridge(config-if)# power client n
(where n is a value of 13, 16, 19, 22, 23, 24, or maximum)
The bridge does not perform any action if this command is used.
•
CSCea75989—The non-root bridge does not reset the dot11 association counters when it reassociates to
the root bridge.
Workaround:
•
CSCea81730—The web interface for the non-root bridge incorrectly displays the root-bridge MAC
address on the radio interface.
Workaround:
•
CSCeb03832—Bridge does not detect some invalid software images during upgrade.
Workaround: Ensure the correct bridge image file (c1410-k9w7-tar.122-11.JA.tar) is used during
software upgrade.
•
CSCeb04390—Bridge does not detect simultaneous software upgrades from different interfaces.
Workaround: Ensure that the software upgrade is performed by only one person using one interface.
•
CSCeb05054—Multiple non-root bridges do not associate to root bridge after a speed change.
The root bridge in a point-to-multipoint link does not allow non-root bridges to reassociate after
changing the operating speed, until the root bridge has rebooted (power turned off and on).
Workaround: After changing the speed on a point-to-multipoint link, you must reboot the root bridge
(turn power off and on).
•
CSCeb08817—Root bridge cannot ping a non-root bridge after reassociation.
Workaround: Use the CLI clear arp-cache command to clear the root bridge ARP cache.

Cisco TAC Website
The Cisco TAC website provides online documents and tools to help troubleshoot and resolve technical
issues with Cisco products and technologies. To access the Cisco TAC website, go to this URL:
http://www.cisco.com/tac
All customers, partners, and resellers who have a valid Cisco service contract have complete access to
the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website
require a Cisco.com login ID and password. If you have a valid service contract but do not have a login
ID or password, go to this URL to register:
http://tools.cisco.com/RPF/register/register.do
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco
TAC website, you can open a case online at this URL:
https://sso.cisco.com/autho/forms/CDClogin.html
If you have Internet access, we recommend that you open P3 and P4 cases online so that you can fully
describe the situation and attach any necessary files.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These
classifications are assigned when severe network degradation significantly impacts business operations.
When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer
automatically opens a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:

Before calling, please check with your network operations center to determine the Cisco support services
