Introduction

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 1100 and 1200 series access points using the command-line interface (CLI), the browser-based management system, or Simple Network Management Protocol (SNMP).

System Requirements

You can install Cisco IOS Release 12.2(11)JA1 on 1100 series access points and on 1200 series access points that have been configured at the factory to run Cisco IOS software (model AP1230).

To install this release on a 1200 series access point that does not run IOS software, use the conversion utility to convert to IOS software without losing your current configuration. To convert to IOS software without saving your configuration, load the conversion image. The access point reboots with IOS software and factory default settings. Your 1200 series access point must run one of these VxWorks versions before you can convert to IOS software: 12.03T, 12.02T1, 12.01T1, 12.00T, 11.56, or 11.54T. If your access point runs version 12.04, you must downgrade to a supported VxWorks version before upgrading to IOS software.

Note Cisco Aironet 340 and 350 Series Access Points do not support IOS software. Cisco Aironet 1200 Series Access Points not configured at the factory to run IOS software can be converted to run IOS software. Do not attempt to load an IOS image on 340 and 350 series access points, or on a 1200 series access point that has not been converted to run IOS software.

Finding the IOS Software Version

To find the version of IOS software 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 version

Cisco Internetwork Operating System Software

IOS (tm) C1200 Software (C1200-K9W7-M), Version 12.2(8)JA

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

On access points running IOS software, 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 software, the software version appears at the top left of most pages in the web-browser interface.

Installation Notes

This section contains information you should keep in mind when installing 1100 and 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 1100 and 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.

Power Considerations

This section describes issues you should consider before applying power to an access point.

Caution The operational voltage range for 1100 series access points is 24 to 60 VDC, and the nominal voltage is 48 VDC. Voltage higher than 60 VDC can damage the equipment.
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 1 shows the power configuration that can shut down the port on the patch panel or powered switch.

Figure 1 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.

Antenna Installation

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.

Important Notes

This section describes important information about the access point.

Radio MAC Address Appears in ACU

When a Cisco Aironet client device associates to an 1100 or 1200 series access point running IOS software, 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. The MAC address for the access point Ethernet port is printed on the label on the back of the access point.

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 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.

Repeater Access Points Running IOS Software Cannot Associate to Parent Access Points Not Running IOS Software

Repeater access points running Cisco IOS software cannot associate to parent access points that do not run IOS software (340 and 350 series access points, and 1200 series access points that have not been converted to run IOS software).

Repeater Access Points Cannot Be Configured As WDS Access Points

Repeater access points do not support WDS. You cannot configure a repeater access point as a WDS access point, and if a root access point becomes a repeater in fallback mode, it cannot provide WDS.

Crossover Cable Sometimes Needed When Ethernet Speed and Duplex Set to Fixed on 1100 Series Access Points

If you change the speed and duplex settings from auto to fixed on an 1100 series access point's Ethernet port, the auto-MDIX feature on the port is disabled. When auto-MDIX is disabled, you must determine whether to use a straight-through or a crossover cable to connect the access point Ethernet port to another device. If the Ethernet link goes down after you set the speed and duplex to fixed, try changing the Ethernet cable from crossover to straight-through or from straight-through to crossover.

Cannot Perform Link Tests on Non-Cisco Aironet Client Devices

The link test feature on the web-browser interface does not support non-Cisco Aironet client devices.

Firmware Upgrade Sometimes Fails Using Microsoft Internet Explorer 5.01 SP2

A firmware upgrade sometimes fails when you use Microsoft Internet Explorer version 5.01 SP2 to upgrade firmware using the HTTP Upgrade page in the web-browser interface. Use a later version of Microsoft Internet Explorer to perform HTTP firmware upgrades.

Caveats

This section lists open and resolved caveats in Cisco IOS Release 12.2(11)JA1.

Open Caveats

These caveats are open in Cisco IOS Release 12.2(11)JA1:

•CSCea88706—You cannot modify existing MAC address and Ethertype filters on the access point web-browser interface.

Workaround: Instead of modifying the filter, delete the filter and recreate it using the web-browser interface.

•CSCea88862—You cannot run a link test using thousands of packets on the web-browser interface.

Workaround: When running link tests on the web-browser interface, limit the test to hundreds of packets, or use the CLI to run link tests using thousands of packets.

•CSCea89985—When you configure hot standby mode using a broadcast MAC address to specify the access point to be monitored, the access point generates a traceback.

Workaround: Do not use a broadcast MAC address when configuring hot standby.

•CSCea91378—When you run a carrier busy test on the web-browser interface when the access point radio is disabled, the web-browser interface reports that the test failed.

Workaround: Enable the radio interface before running the carrier busy test on the web-browser interface, or run the carrier busy test on the CLI.

•CSCea91424—When a CCKM client device roams to a foreign network using proxy Mobile IP, these error messages sometimes appear even though the client associates successfully: 

Apr 30 20:36:34.521: %DOT11-7-AUTH_FAILED: Station 000b.fd75.4180 Authentication 
failed

Apr 30 20:36:37.712: %DOT11-6-ASSOC: Interface Dot11Radio0, Station STL-CLIENT-3 
000b.fd75.4180 Associated KEY_MGMT[CCKM]

You can ignore these messages.

•CSCeb06139—When several mobile clients are using Cisco Centralized Key Management (CCKM), the access point sometimes reboots when you enter the show wlccp wds mn detail command and the command displays the mobile node details at the same time that a mobile node expires and is deleted.

Workaround: Before entering the show wlccp wds mn detail command, enter terminal length 0 in privileged EXEC mode to display the show wlccp wds mn detail command output without breaking it into multiple pages.

•CSCin44512—If 8 or more VLANs are configured on your access point, you cannot apply filters using the Apply Filters page in the web-browser interface.

Workaround: Use the CLI to apply filters when 8 or more VLANs are enabled.

•CSCin44591—When you use the web-browser interface to enable PSPF on a non-native VLAN, PSPF does not work.

Workaround: Use the CLI to enable PSPF on a non-native VLAN.

Resolved Caveats

These caveats are resolved in Cisco IOS Release 12.2(11)JA1:

•CSCea02355—Rare ip packets no longer cause an input queue wedge.

•CSCdz29724—It is no longer possible to enumerate existing accounts on an 1100 or 1200 series access point.

•CSCeb49869—Sending a malformed URL to an 1100 or 1200 series access point no longer causes the device to reset.

•CSCin46150—User-based VLAN assignments now work properly. For example, when a RADIUS server is configured to allow a different VLAN (such as 10) to be assigned to a user other than the one established with the SSID (such as 5), the client is assigned to the VLAN sent by the server (10).
