Release Notes for Cisco Aironet 1410 Wireless Bridges for Cisco IOS Release 12.3(8)JA1
March 23, 2006
These release notes describe new features and open and resolved caveats for Cisco IOS Release 12.3(8)JA1. They also provide important information about the Cisco Aironet 1410 Wireless Bridge (hereafter called bridge).
These release notes contain the following sections:
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).
You can install Cisco IOS Release 12.3(8)JA1 on all 1400 series bridges.
Finding the Software Version
To find the version of Cisco IOS software 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(13)JA2:bridge> show versionCisco Internetwork Operating System SoftwareIOS (tm) C1410 Software (C1410-K9W7-M), Version 12.2(13)JA2Copyright (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.

•IBNS 802.1X Supplicant—This feature supports an 802.1X for EAP-FAST and EAP-TLS that provides a secure method for enabling 802.1X authentication on the that are connected to access points.
This section contains important information to keep in mind when installing your bridge.
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 a customer-supplied 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.
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.
This section describes important information about the bridge.
Default SSID and Distance Settings Change 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.
In Install Automatic Mode, the default distance setting is 99 km. When you change the role in radio network from Install Automatic Mode to Root or Non-Root, the distance setting changes automatically from 99 km to 0 km.
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.
CLI Command power client n Is Not Supported
The bridge does not support the power client n configuration interface command in the web-browser or CLI interfaces. 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 per second.
b. Medium blinking rate of 2 blinks per second.
c. Fast blinking rate of 4 blinks per 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.
Telnet Session Sometimes Hangs or Will Not Start During Heavy Traffic
When the bridge is transmitting and receiving heavy traffic, you sometimes cannot start a Telnet session and some existing Telnet sessions freeze or hang. However, this behavior is expected because the bridge gives top priority to data traffic and a lower priority to Telnet traffic.
This section lists open and resolved caveats for the bridge.
These caveats are open in Cisco IOS Release 12.3(8)JA1:
•CSCsc21018—1400 Series bridge shows non-root IP address as 0.0.0.0
When non-root bridges are configured to use DHCP IP Address, the show dot11 association output shows non-root IP address as 0.0.0.0 despite the fact that IP address has been successful allocated and received by the non-root bridge. This does not affect any IP communication of root or non-root bridge at all.
Workaround: Issuing a shutdown and no shutdown command on the non-root radio interface will allow non-root to re-associate to the root bridge after it receives the DHCP IP address and communicates the IP address to the root bridge.
Alternatively, use the mac-address command to set the BVI 1 interface mac-address to the same as the non-root radio mac-address will allow root bridge to snoop the DHCP IP address and update the association table automatically. Normally, BVI 1 mac-address is the FastEthernet mac-address of the bridge. All IP traffic uses this BVI mac-address while root bridge keeps track of non-root with the uplink.
•CSCed36462—Per-VLAN crypto settings are nonfunctional with wireless bridges.
On wireless bridges, all VLANs traversing the bridge link must use the same encryption settings. To avoid confusion, do not use the "vlan <vlan-id> keyword on the encryption command as shown in the following example:interface dot11radio0 encryption key 1 size 128bit AAAAABBBBBCCCCCDDDDDEEEEEF transmit-key encryption mode wep mandatory mic
•CSCsb04925—Bridge displays junk characters when show controllers command is issued.
When show controllers dot110 is entered, it displays a serial number with a junk character.
•CSCsc69991—GE: Non root bridge issues invalid DHCP failure message on reload
When a non-root bridge is configured for open authentication, VLANs enabled, and DHCP is reloaded, the following message is seen on the console, yet the bridge is still able to get a DHCP address and pass traffic:Process= "Soap Upgrade fetch Config File", ipl= 0, pid= 53".
Workaround: None. This is a cosmetic caveat that does not affect bridge functionality.
Resolved Caveats in Cisco IOS Release 12.3(8)JA1
The following caveats are resolved in Cisco IOS Release 12.3(8)JA1:
•CSCsc60665—1400 series bridge in non root mode can now reassociate to root after being
•CSCsc98494—1400 series bridge no longer transmits excessive probe requests in channel 149 during channel scan.
Resolved Caveats in Cisco IOS Release 12.3(8)JA
The following caveats are resolved in Cisco IOS Release 12.3(8)JA:
•CSCsb60439—VLANs can now be created on the bridge GUI.
•CSCsb63034—1400 series bridge in non-root bridge mode no longer shows a no temperature warning message.
•CSCed36477—VLAN keyword with encryption command on bridges is no longer limited.
•CSCsa68144—Default bridge configuration is now valid.

Stacking Bridges Section Changes
The separation distance between the two stacked bridge antennas is a minimum of 6.56 ft (2 m).
Optional Antenna Clarification
The Quick Start Guide: Cisco Aironet 1400 Series Wireless Bridge states on page 6 that the external antenna version of the bridge connects to an optional antenna. The statement is incorrect. The external antenna of the bridge has no installed antenna. The customer must purchase the antenna for the this version. There are three antenna options available for the external antenna version and the customer must purchase at least one to make the bridge operational.
A revision to this guide will be released at a future date.
