Introduction
The Cisco Aironet 1300 Series Outdoor Access Point/Bridge is an 802.11b/g device that provides high speed and cost-effective wireless connectivity between multiple fixed or mobile networks and clients. The flexibility of the device allows it to operate as an access point, wireless bridge, or workgroup bridge. Building a metropolitan area wireless infrastructure with the access point/bridge provides deployment personnel with a flexible, easy to use solution that meets the security requirements of wide area networking professionals.
The access point/bridge supports the 802.11b/g standard, providing 54-Mbps data rates with a proven, secure technology. Cisco makes the maintenance and installation of the access point/bridge easy by integrating it with your wired network using the Cisco SWAN solution. Based on the Cisco IOS operating system, the access point/bridge includes advanced features such as Fast Secure Roaming, QoS, and VLANs.
System Requirements
You can install Cisco IOS Release 12.3(7)JA5 on any 1300 series outdoor access point/bridge.
Finding the IOS Software Version
To determine the version of IOS running on your access point/bridge, use a Telnet session to log into the access point/bridge and enter the show version EXEC command. This example shows command output from an access point/bridge running Cisco IOS Release 12.3(7)JA5:

Updates to Existing Features
These existing features are supported on access points/bridges running Cisco IOS Release 12.3(7)JA:
•
•
New Features
This release does not contain new features. It supports the features introduced in Cisco IOS Release 12.3(7)JA. This section lists new features in Cisco IOS Release 12.3(7)JA for the access point/bridge:
•
•
•
AAA Cache and Profile
AAA cache and profile is a new capability to cache the information returned from the RADIUS or TACACS+ server a more efficient handling of the authentication process.
SSH v2 Server Support
SSH v2 server support is a standards-based protocol to provide secure Telnet capability for router configuration and administration.
NAC-L2 IEEE 802.1x Support
Network Admission Control (NAC) L2 IEEE 802.1x extends NAC support to layer 2 switches and wireless access points. Combining it with 802.1x provides a unified authentication and posture validation mechanism at the layer 2 network edge. This helps protect the network from attack by machines with insufficient antivirus posture. Performing posture validation at the edge maximizes the portion of the network which is protected and allows posture validation to be performed with a VLAN.
If the access point/bridge is configured to support EAP authentication of clients and VLAN override is enabled as part of NAC on the RADIUS server, no additional configuration of the access point/bridge is required to support NAC.
Procedures for configuring the access point/bridge to support EAP authentication of clients is on Cisco.com at the following URL:

FCC Safety Compliance Statement
FCC Compliance with its action in ET Docket 96-8, has adopted a safety standard for human exposure to RF electromagnetic energy emitted by FCC-certified eqipment. 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
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!

1300 Series Installation
The 1300 series access point/bridge is available in two configurations:
•
•
Note
Note
Personnel installing the access point/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.
Important Notes
This section describes important information about the access point/bridge.
Default IP Address Behavior
When an unconfigured outdoor access point/bridge boots, it attempts to obtain an IP address from a DHCP server. If it fails to locate a DHCP server, it continues attempting to request an IP address from the DHCP server. To eliminate this behavior, you must access the access point/bridge through its console port and assign a static IP address.
If you want to reset the access point/bridge to its default settings and a static IP address, use the write erase or erase /all nvram command. If you want to erase everything including the static IP address, in addition to the above commands, use the erase and erase boot static-ipaddr static-ipmask command.
Caution
Default Username and Password Are Cisco
When you open the 1300 series interface, you must enter a username and password. The default username for administrator login is Cisco, and the default password is Cisco. Both the username and password are case sensitive.
Changes to the Default Configuration—Radios Disabled and No Default SSID
In this release, the radio is disabled by default, and there is no default SSID. You must create an SSID and enable the radio before the access point/bridge will allow wireless associations from other devices. These changes to the default configuration improve the security of newly installed access points and bridges.
Enabling MBSSIDs Without VLANs Disables Radio Interface
If you use the mbssid configuration interface command to enable multiple BSSIDs on a specific radio interface but VLANs are not configured on the access point, the access point disables the radio interface. To re-enable the radio, you must shut down the radio, disable multiple BSSIDs, and re-enable the radio. This example shows the commands you use to re-enable the radio:
AP(config)# interface d1AP(config-if)# shutAP(config-if)# no mbssidAP(config-if)# no shutAfter you re-enable the radio, you can enable VLANs on the access point and enable multiple BSSIDs.
Some Client Devices Cannot Associate When QoS Is Configured
Some wireless client devices, including Dell Axim handhelds and Hewlett-Packard iPaq HX4700 handhelds, cannot associate to an access point when the access point is configured for QoS. To allow these clients to associate, disable QoS on the access point. You can use the QoS Policies page on the access point GUI to disable QoS, or enter this command on the CLI:
ap(config-if)#no dot11 qos mode
Proxy Mobile-IP Feature Removed
The proxy Mobile-IP feature is not supported in Cisco IOS Releases 12.3(2)JA and later.
WPA/2 With Concatenation Not Supported
Cisco IOS Release 12.3(7)JA5 does not support this feature.
Hard Coded Ethernet Port Settings Degrade GUI Performance
Ethernet port settings on the access point/bridge must be set to auto speed and auto negotiation. If you use any other setting, the GUI operates very slowly.
TACACS+ and DHCP IP Address Sometimes Locks Out Administrators
When you configure an access point for TACACS+ administration and to receive an IP address from the DHCP server, administrators might be locked out of the access point after it reboots if the administrator does not have a local username and password configured on the access point. This issue does not affect access points configured with a static IP address. Administrators who have been locked out must regain access by using the mode button to reset the unit to default settings.
Access Point/Bridge Does Not Support Loopback Interface
When configuring the access point/bridge as an access point, you must not configure a loopback interface.
Caution
Non-Cisco Aironet 802.11g Clients Might Require Firmware Upgrade
Some non-Cisco Aironet 802.11g client devices require a firmware upgrade before they can associate to the 802.11g radio in the access point/bridge when it is configured as an access point or workgroup bridge. If your non-Cisco Aironet 802.11g client device does not associate to the access point/bridge, download and install the latest client firmware from the manufacturer's website.
Throughput Option for 802.11g Radio Blocks Association by 802.11b Clients
When you configure the 802.11g 1300 series radio for best throughput, the access point/bridge sets all data rates to basic (required). This setting blocks association from 802.11b client devices. The best throughput option appears on the web-browser interface Radio0-802.11G Settings pages and in the speed CLI configuration interface command.
Use force-reload Option with archive download-sw Command
When you upgrade access point or bridge system software by entering the archive download-sw command on the CLI, you must use the force-reload option. If the access point or bridge does not reload the Flash after the upgrade, the pages in the web-browser interface might not reflect the upgrade. This example shows how to upgrade system software successfully using the archive download-sw command:
AP# archive download-sw /force-reload /overwrite tftp:/10.0.0.1/ image-name (image name)Radio MAC Address Appears in ACU
When a Cisco Aironet client device associates to an access point or bridge running IOS software, the device's MAC address that appears on the Status page in the Aironet Client Utility (ACU) is the MAC address for the access point or bridge radio. The MAC address for the access point or bridge's Ethernet port is printed on the label on the back of the access point or bridge.
Radio MAC Address Appears in Access Point/Bridge Event Log
When a client device roams from an access point (such as access point alpha) to another access point (access point bravo), a message appears in the event log on access point alpha stating that the client roamed to access point bravo. The MAC address that appears in the event message is the MAC address for the access point/bridge.
Mask Field on IP Filters Page Behaves the Same As in CLI
In Cisco IOS Release 12.2(8)JA and later, the mask that you enter in the Mask field on the IP Filters page in the access point/bridge GUI behaves the same way as a mask that you enter in the CLI. If you enter 255.255.255.255 as the mask, the access point/bridge accepts any IP address. If you enter 0.0.0.0, the access point/bridge looks for an exact match with the IP address that you entered in the IP Address field.
System Software Upgrade Sometimes Fails Using Microsoft Internet Explorer 5.01 SP2
A system software upgrade sometimes fails when you use Microsoft Internet Explorer version 5.01 SP2 to upgrade system software using the HTTP Upgrade page in the web-browser interface. Use a later version of Microsoft Internet Explorer to perform HTTP system software upgrades, or use TFTP to upgrade system software. Click this URL to browse to the Cisco 1300 Series Wireless Bridge Software Configuration Guide for complete instructions on performing software upgrades:
Corrupt EAP Packet Sometimes Causes Error Message
During client authentication, the access point/bridge sometimes receives a corrupt EAP packet and displays this error message:
Oct 1 09:00:51.642 R: %SYS-2-GETBUF: Bad getbuffer, bytes= 28165 -Process= "Dot11 Dot1x process", ipl= 0, pid= 32 -Traceback= A2F98 3C441C 3C7184 3C604C 3C5E14 3C5430 124DDCYou can ignore these messages.
When Cipher is TKIP Only, Key Management Must Be Enabled
When "Cipher TKIP" is configured on a VLAN, the SSID(s) for that VLAN must use WPA or CCKM key management. If you do not configure the SSID(s) for that VLAN with WPA or CCKM, client authentication fails on the SSIDs.
Non-Cisco Aironet Clients Sometimes Fail 802.1x Authentication
Some non-Cisco Aironet client adapters do not perform 802.1x authentication to the access point/bridge unless you configure Open authentication with EAP. To allow both Cisco Aironet clients using LEAP and non-Cisco Aironet clients using LEAP to associate using the same SSID, you might need to configure the SSID for both Network EAP authentication and Open authentication with EAP.
Pings and Link Tests Sometimes Fail to Clients with both Wired and Wireless Network Connections
When you ping or run a link test from an access point to a client device installed in a PC running Microsoft Windows 2000, the ping or link test sometimes fails when the client has both wired and wireless connections to the LAN. Microsoft does not recommend this configuration. For more information, refer to Microsoft Knowledge Base article 157025 at this URL:
http://support.microsoft.com/default.aspx?scid=kb;en-us;157025&Product=win2000
Limitation to PAgP Redundancy on Switches Connected by Bridge Links
When running PAgP on switched connected to series bridges, for ethernet traffic redundancy and load balance be aware that PAgP switchover takes at least 30 seconds, which is too slow to maintain certain traffic (for example, TCP) when switching from port to the other. There is no workaround for this limitation.
Ethernet Duplex Settings
The access point/bridge is implemented with an unmanaged and unconfigurable 10/100baseT switch embedded in the power injector. All ports on the switch are set for auto-speed, auto-duplex, and auto-MDIX. Port 0 on the switch is used for the coaxial link to the access point/bridge. Port 1 on the switch is used for the RJ45 jack on the power injector.
The speed and duplex settings on the access point/bridge FastEthernet0 interface apply only to the link between the access point/bridge port and port 0 on the power injector. They are entirely independent of the speed and duplex settings used on the RJ45 port (port 1) on the power injector. Therefore, for best performance, you should not change the port 0 default settings. The default settings result in a 100Mbps, full-duplex configuration used on the link between the access point/bridge and the power injector switch.
The connecting port (the port on the device connected to the power injector's RJ45) must be set to half duplex or (preferably) auto duplex. If it is set to auto-duplex, the power injector switch port should negotiate full duplex. If it is set to half duplex, the power injector switch port falls back to half-duplex. The connecting port must not be configured to full duplex. If it is, the power injector switch port fails to negotiate full-duplex, falls back to half duplex, which causes a duplex mismatch.
The following guidelines for setting Ethernet speed and duplex should always be observed:

Failure to follow these guidelines will result in lost data due to late collisions, CRC errors, etc.
Maximum Number of Access Points That Can Associate to WDS is 60
In Cisco IOS Release 12.3(7)JA and later, the maximum number of access points that can associate to a WDS is limited to 60.
