Release Notes for 1200 Series Access Points
for Cisco IOS Release 12.2(8)JA
February 18, 2003
These release notes describe features, enhancements, and caveats for Cisco IOS Release 12.2(8)JA. They also provide important information about 1200 series access points.
These release notes contain the following sections:
The Cisco Aironet Access Point is a wireless LAN transceiver that acts as the connection point between wireless and wired networks or as the center point of a standalone wireless network. In large installations, the roaming functionality provided by multiple access points enables wireless users to move freely throughout the facility while maintaining uninterrupted access to the network.
You can configure and monitor 1200 series access points using the command-line interface (CLI), the browser-based management system, or Simple Network Management Protocol (SNMP).
You can install Cisco IOS Release 12.2(8)JA on a 1200 series access point that has been configured at the factory to run Cisco IOS.
Note Cisco Aironet 340 and 350 Series Access Points and 1200 series access points that currently run firmware version 12.01T or earlier do not support IOS. Do not attempt to load an IOS image on an access point that does not run IOS.
Determining the Software Version
To determine the version of IOS running on your access point, use a Telnet session to log into the access point and enter the show version EXEC command. This example shows command output from an access point running Cisco IOS Release 12.2(8)JA:ap1200>show versionCisco Internetwork Operating System SoftwareIOS (tm) C1200 Software (C1200-K9W7-M), Version 12.2(8)JACopyright (c) 1986-2003 by Cisco Systems, Inc.
On access points running IOS, you can also find the software version on the System Software Version page in the access point's web-browser interface.
If your access point does not run IOS, the software version appears at the top left of most pages in the web-browser interface. The home page on access points not running IOS looks like the page in Figure 1.

Cisco IOS Release 12.2(8)JA can be loaded on 1200 series access points that are configured at the factory for IOS.
Support for TACACS+
Cisco IOS Release 12.2(8)JA supports TACACS+. TACACS+ provides detailed accounting information and flexible administrative control over authentication and authorization processes. It provides secure, centralized validation of administrators attempting to gain access to your access point.
This section contains information you should keep in mind when installing 1200 series access points.
Installation in Environmental Air Space
This section provides information on installing 1200 series access points in environmental air space, such as above suspended ceilings.
Cisco Aironet 1200 Series Access Points provide adequate fire resistance and low smoke-producing characteristics suitable for operation in a building's environmental air space, such as above suspended ceilings, in accordance with Section 300-22(C) of the National Electrical Code (NEC) and Sections 2-128, 12-010(3) and 12-100 of the Canadian Electrical Code, Part 1, C22.1.
Caution The power injector is not intended for use in extremely high or low temperatures or in environmental air spaces, such as above suspended ceilings.
Note If you plan to mount a 1200 series access point with a 5-GHz radio in an area subject to environmental air space, Cisco recommends that you mount the access point horizontally so that its antennas point down. Doing so ensures that the access point complies with regulatory requirements for environmental air space with the 5-GHz radio installed.
This section describes issues you should consider before applying power to an access point.
Caution The nominal voltage for 1200 series access points is 48 VDC, and the access point is operational up to 60 VDC. Voltage higher than 60 VDC can damage the equipment.
Caution Cisco Aironet power injectors are designed for use with Cisco Aironet access points and bridges only. Do not use the power injector with any other Ethernet-ready device. Using the power injector with other Ethernet-ready devices can damage the equipment.
Use Only One Power Option
You cannot provide redundant power to the access point with both DC power to its power port and inline power from a patch panel or powered switch to the access point's Ethernet port. If you apply power to the access point from both sources, the switch or power patch panel might shut down the port to which the access point is connected. Figure 2 shows the power configuration that can shut down the port on the patch panel or powered switch.
Figure 2 Improper Power Configuration Using Two Power Sources
Operating 5-GHz Radio Requires Power Injector, Power Module, or Catalyst 3550-24 PWR Switch
The 1200 series power injector and the 1200 series power module support operation of the 5-GHz radio in the access point. Currently, the Catalyst 3550-24 PWR switch supports power for both the 2.4-GHz radio and the 5-GHz radio. Other switches and power patch panels might not provide enough power for the 5-GHz radio.
Access Point Requires 1200 Series Universal Power Supply and Power Injector
The 350 series universal power supply and power injector are not compatible with the 1200 series access point. If you use a power injector or a power module to provide power to a 1200 series access point, you must use a 1200 series universal power supply. If you need to use a power injector to inject power into the access point's Ethernet port, you must use a 1200 series power injector.
For instructions on the proper installation and grounding of external antennas for 1200 series access points, refer to the National Fire Protection Association's NFPA 70, National Electrical Code, Article 810, and the Canadian Standards Association's Canadian Electrical Code, Section 54.
Warning Do not install 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.
This section describes important information about the access point.
Radio MAC Address Appears in ACU
When a Cisco Aironet client device associates to a 1200 series access point running IOS, the access point MAC address that appears on the Status page in the Aironet Client Utility (ACU) is the MAC address for the access point radio. The MAC address for the access point Ethernet port is printed on the label on the back of the access point.
Radio MAC Address Appears in Access Point 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 radio in access point bravo instead of the Ethernet port in access point bravo.
Mask Field on IP Filters Page Behaves the Same as in CLI
In Cisco IOS Release 12.2(8)JA, the mask that you enter in the Mask field on the IP Filters page in the access point GUI behaves the same way that a mask behaves when you enter it in the CLI. If you enter 255.255.255.255 as the mask, the access point accepts any IP address. If you enter 0.0.0.0, the access point looks for an exact match with the IP address that you entered in the IP Address field.
This section lists open and resolved caveats in Cisco IOS Release 12.2(8)JA.
These caveats are open in Cisco IOS Release 12.2(8)JA:
•CSCea04097—If you remove a RADIUS server from the access point configuration while a device is attempting to authenticate to the server through the access point, the access point sometimes reboots. Workaround: make sure no devices are attempting to authenticate through the access point before you change or remove a RADIUS server from the access point configuration.
•CSCea04766—You cannot perform a link test from the access point to a client device that is associated on a VLAN other than the native VLAN.
•CSCea14120—SSH is not enabled when you select Enabled on the Telnet/SSH page in the GUI. Workaround: use the CLI to enable SSH. Click this URL to browse to complete instructions for enabling SSH in Cisco IOS:
•CSCea14429—When the access point is in repeater mode, you cannot use the GUI to disable authentication modes for the repeater radio. Workaround: use the CLI to disable authentication types for the repeater radio, or use the GUI to change the radio role back to root, disable the authentication types, and then set the role back to repeater.
•CSCdz35651—When you enter the debug all command in the CLI, the access point sometimes reboots.
•CSCdz41787—The access point GUI does not work with Netscape Navigator version 6.0. The access point web-browser interface is fully compatible with Netscape Navigator, version 4.x, and Microsoft Internet Explorer, version 5.x or later.
•CSCdz44075—The status LED on top of the access point does not turn red to indicate that the access point is undergoing a firmware upgrade.
•CSCdz45435—Access point loses synchronization with the NTP server. If NTP is enabled, the access point is able to synchronize its time with the time server. However, after 15 minutes the access point time is no longer syncronized and will not syncronize again until the access point is rebooted or NTP is disabled and re-enabled. When the time is unsyncronized, the pages in the access point web-browser interface display access point uptime instead of clock time.
•CSCdz51009—Firmware upgrade fails when you use Microsoft Internet Explorer version 5.01 SP2 to upgrade firmware using the HTTP Upgrade page in the GUI. Workaround: Use a later version of Microsoft Internet Explorer to perform HTTP firmware upgrades.
•CSCdz65877—When a workgroup bridge or a repeater access point with MIC and CDP enabled associates to your access point using a non-native VLAN, your access point displays this message:ap: Critical Memory allocation of 760 bytes failed from 0xA4B54
Workaround: Disable MIC or CDP on workgroup bridges or repeaters that are associated to your access point on non-native VLANs.
•CSCdz73701—You cannot add the access point as a managed device to these components of CiscoWorks: CD One Fifth Edition version 2.1, Resource Manager Essentials version 3.4, and Resource Manager Essentials Incremental Device Support version 3.4.
•CSCdz73769—You cannot view the access point in CiscoView version 5.4.
•CSCdz76044—The Network Map page in the access point GUI incorrectly lists 1230 access points as client devices rather than as access points.
•CSCdz76076—The Refresh button on the Network Map page in the access point GUI does not refresh the page. Workaround: Use the refresh button on your browser to refresh the Network Map page.
•CSCdz80894—The statistics counters for packets received over the radio interfaces on the Network Interfaces page always indicate 0 regardless of the number of packets received.
•CSCdz84002—When you attempt to load an unsupported file format for the New Startup Configuration File in the access point GUI, the access point sometimes loses its bridge virtual interface (BVI). Workaround: Press and hold the MODE button on the back of the access point to reload the configuration.
•CSCdz84370—Access points that are not running IOS (340, 350, and 1200 series access points) cannot serve as the parent for a 1230 access point in repeater mode.
•CSCdz88122—If the parent of a repeater access point shuts down, the repeater does not roam to another parent access point until the repeater reboots.
•CSCdz89120—The Use Daylight Savings Time button on the Services: NTP page does not adjust the access point clock to Daylight Saving Time.
No caveats are resolved in Cisco IOS Release 12.2(8)JA.
