Introduction

The Cisco Aironet 1400 Series 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 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 and supports both point-to-point and point-to-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

You should install Cisco IOS Release 12.2(13)JA on your bridge to incorporate the fixes identified in the Resolved Caveats section.

Finding the Software Version

To find 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:

bridge> show version

Cisco Internetwork Operating System Software

IOS (tm) C1410 Software (C1410-K9W7-M), Version 12.2(11)JA

Copyright (c) 1986-2003 by Cisco Systems, Inc.

You can also find the software version on the System Software Version page in the bridge's web-browser interface.

Installation Notes

This section contains important information to keep in mind when installing your bridge.

Bridge Installation

The bridge is available in two configurations:

•Integrated antenna bridge (with 22.5-dBi directional antenna)

•External antenna bridge (with antenna connector for use with an external antenna)

---

Note To meet regulatory restrictions, the external antenna bridge configuration and the external antenna must be professionally installed.

---

---

Note When installing the dual-coax cable, it is acceptable to unzip or pull the two cables apart at the ends if more separation is needed between the male F connectors.

---

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.

Default SSID Changes When You Change Role in Radio Network

If the bridge's SSID has not been changed from the default setting and you select Install Automatic Mode as the bridge's role in radio network setting, the SSID automatically changes from tsunami to autoinstall. When you change the role in radio network from Install Automatic Mode to Root or Non-Root, the SSID changes automatically from autoinstall back to tsunami. However, if you change the SSID from its default setting, changing the role in radio network setting does not change the SSID.

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, but 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.

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 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 12, 15, 18, 21, 22, 23, 24, or maximum)

The bridge does not perform any action when you enter this command.

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 supports only one bridge virtual interface (BVI). Multiple BVIs should not be configured because the ARP table may become corrupted.

Bridge Power Up LED Colors

During power up the bridge LEDs display the following color sequences:

1. The Install LED is initially turned off.

2. The Install LED turns amber.

3. The Status LED turns amber during the boot loader process.

4. The Ethernet, Status, and Radio LEDs turn green during the loading of the operating system.

5. The Ethernet, Status, and Radio LEDs turn amber during the loop-back test.

6. The Status LED starts to blink green then the Ethernet LED starts to blink green.

7. The Ethernet, Status, and Radio LEDs blink amber twice to indicate that the auto install process has started.

8. During the auto install process, the Ethernet, Status, and Radio LEDs turn off for a short time period then go through a blinking sequence twice. Each LED sequentially blinks at the following rates before becoming continuously amber:

a. Slow blinking rate of 1 blink/second.

b. Medium blinking rate of 2 blinks/second.

c. Fast blinking rate of 4 blinks/second.

9. The Install LED starts to blink amber to indicate that the bridge is searching for a root bridge.

10. When the bridge associates to a root bridge, the Install LED turns amber.

11. When the bridge becomes a root bridge and is waiting for a non-root bridge to associate, the Install LED blinks green.

12. When the root bridge has a non-root bridge associated, the Install LED turns green.

Bridge Cannot Detect Simultaneous Image Downloads

Do not attempt to load software images into the bridge from both a Telnet session and console session simultaneously. The bridge cannot detect that two images are being loaded at the same time. For best results, use the archive download command in the CLI.

Bridge Cannot Detect Invalid Software When Using copy Command

The bridge sometimes cannot detect invalid software images when you load software using the copy command. For best results, use the archive download command in the CLI to load new software.

Caveats

This section lists open and resolved caveats in Cisco IOS Release 12.2(13)JA for the bridge.

Open Caveats

These caveats are open in Cisco IOS Release 12.2(13)JA for the bridge:

•CSCeb14603—When the bridge is transmitting and receiving heavy traffic, you cannot start a Telnet session and existing Telnet sessions freeze or hang. There is no workaround for this issue.

•CSCec40452—When you run a link test or install the bridge using the autoinstall mode, the RSSI reading is 4 dB lower than actual at room temperature and 8 dB lower than actual when the outdoor ambient temperature is higher than approximately 45° C. There is no workaround for this issue.

•CSCin57580—MAC address filtering sometimes fails to stop traffic from filtered addresses. There is no workaround for this issue.

Resolved Caveats

These caveats are resolved in Cisco IOS Release 12.2(13)JA:

•CSCdu53656—A Cisco device running IOS and enabled for the Border Gateway Protocol (BGP) is vulnerable to a Denial of Service (DOS) attack from a malformed BGP packet. The BGP protocol is not enabled by default, and must be configured in order to accept traffic from an explicitly defined peer. Unless the malicious traffic appears to be sourced from a configured, trusted peer, it would be difficult to inject a malformed packet. BGP MD5 is a valid workaround for this problem.

Cisco has made free software available to address this problem. For more details, please refer to this advisory, available at http://www.cisco.com/warp/public/707/cisco-sa-20040616-bgp.shtml.

•CSCea28131—A Cisco device running IOS and enabled for the Border Gateway Protocol (BGP) is vulnerable to a Denial of Service (DOS) attack from a malformed BGP packet. The BGP protocol is not enabled by default, and must be configured in order to accept traffic from an explicitly defined peer. Unless the malicious traffic appears to be sourced from a configured, trusted peer, it would be difficult to inject a malformed packet. BGP MD5 is a valid workaround for this problem.

Cisco has made free software available to address this problem. For more details, please refer to this advisory, available at http://www.cisco.com/warp/public/707/cisco-sa-20040616-bgp.shtml.

•CSCea28990—The bridge now passes IP traffic when the bridge # route IP command is configured.

•CSCea57649—The CLI Help command no longer produces incorrect output for the radio interface.

•CSCea77473—HTTP software upgrade no longer fails with Netscape version 7.x.

•CSCea81730—The web interface for the non-root bridge now correctly displays the root-bridge MAC address on the radio page.

•CSCeb05835— The web interface no longer shows incorrect STP Root information on a bridge setup with multiple VLANs.

•CSCeb12740—The virtual radio connection can now be made after the station role is changed.

•CSCeb15923—Radio firmware recovery now works reliably.

•CSCeb17296—The clear dot client command now works with traffic being passed.

Documentation Updates

The Cisco Aironet 1400 Series Wireless Bridge Mounting Instructions provides detailed instructions for installing and mounting the bridge.

Stacking Bridges Section Changes

The separation distance between the two stacked bridge antennas is a minimum of 6.56 feet (2 meters).

New Transmit Power Options for Low-Power Bridges

If your bridge is configured at the factory for use in a regulatory domain other than North America or Korea, the transmit power options for the power local command differ from the power options listed in the Cisco Aironet 1400 Series Bridge Software Configuration Guide and in the Cisco IOS Command Reference for Cisco Aironet Access Points and Bridges. The transmit power options for low-power bridges are 16, 13, 12, 10, 9, 8, 7, and 4 dBm. Note that the maximum transmit power for your bridge depends on your regulatory domain.

New Suspend Option in Bridge Protocol IEEE Command

The bridge protocol ieee command, which enables Spanning Tree Protocol (STP) on the bridge, now contains a suspend option. This option suspends STP on the bridge until you re-enable it.
