Introduction

Cisco Aironet Access Points are wireless LAN transceivers that can act 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 a facility while maintaining uninterrupted access to the network.

Your 1200 series access point can contain two radios: a 2.4-GHz radio in an internal mini-PCI slot and a 5-GHz radio module in an external, modified cardbus slot. The access point supports only one radio of each type. You can configure the radios separately using different settings on each radio.

The access point uses a browser-based management system, but you can also configure the access point using a terminal emulator, a Telnet session, or Simple Network Management Protocol (SNMP).

Installation Notes

You can find the latest release of access point firmware at this URL:

http://www.cisco.com/public/sw-center/sw-wireless.shtml

Installation in Environmental Air Space

The 1200 series access points are suitable for use in environmental air space in accordance with Section 300-22(c) of the National Electrical Code.


Note If you plan to mount the access point in an area exposed to environmental air space with the intention of upgrading to a 5-GHz radio, 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 after the 5-GHz radio is installed.



Caution The Cisco Aironet Power Injector has a smaller operating temperature range (32 to 104 oF; 0 to 40 oC) than the 1200 series access point. The power injector is not intended for use in extremely high or low temperatures or in environmental air spaces, such as above suspended ceilings.

Antenna Installation

For instructions on the proper installation and grounding of external antennas, 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.


Power Considerations

This section describes issues you should consider before applying power to the 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 1200 series access points 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 or Power Module

Only the 1200 series power injector and the 1200 series power module can support operation of the 5-GHz radio in the access point. Currently, switches with inline power and power patch panels do not provide enough power for operation of the 5-GHz radio.

Access Point Requires 1200 Series Universal Power Supply and Power Injector

You must use a 1200 series universal power supply to power the access point. 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. The 350 series universal power supply and power injector are not compatible with the 1200 series access point.

System Requirements

You must have a 1200 series access point to install firmware VxWorks version 12.03T.

Version Supported

Your access point must be running VxWorks firmware version 11.40T or later to install VxWorks firmware version 12.03T.

Limitations and Restrictions

This section describes limitations and restrictions for 1200 series access points.

Removing Power During Firmware Update Can Corrupt Radio Firmware

When you update the firmware on an access point, allow the unit to finish its start-up sequence before removing power.


Caution If you update the firmware and remove power before the unit finishes the start-up sequence, the radio firmware might be corrupted making the unit inoperable.

If the radio firmware is corrupted, the radio indicator (the bottom of the three indicators on top of the access point) is red continuously, and the following error message appears when the access point starts up:

Failed to start driver for port "awc0" (errno=0x006d0002)

The access point should recover from this error automatically.

You can safely shut off power after a firmware update when the configuration management pages reappear in the command-line or web-browser interfaces or when the three status indicators on top of the unit complete the following pattern:

1. All three indicators are continuously green, meaning that the access point is beginning to update the firmware.

2. The middle indicator is continuously green and the top and bottom indicators are off, indicating that the access point is updating the radio firmware.

When the middle indicator blinks or the top and bottom indicators blink, you can shut off power.

EAP Authentication Requires Matching 802.1x Protocol Drafts


Note This section applies to wireless networks set up to use LEAP. If you do not use LEAP on your wireless network, you can skip this section.


Wireless client devices use Extensible Authentication Protocol (EAP) to log onto a network and generate a dynamic, client-specific WEP key for the current logon session. If your wireless network uses WEP without EAP, client devices use the static WEP keys entered in the Aironet Client Utilities.

If you use Network-EAP authentication on your wireless network, your client devices and access points must use the same 802.1x protocol draft. For example, if the radio firmware on the client devices that will associate with an access point is version 4.16, the access point should be configured to use Draft 8 of the 802.1x protocol. Table 1 lists firmware versions for Cisco Aironet products and the draft with which they comply.

Table 1 802.1x Protocol Drafts and Compliant Client Firmware

1 The default draft setting in access point VxWorks firmware version 11.06 and later is 802.1x-2001.


Use the Authenticator Configuration page to select the draft of the 802.1x protocol the access point should use. Follow these steps to set the draft for your access point:


Step 1 Browse to the Authenticator Configuration page in the access point management system:

a. On the Summary Status page, click Setup.

b. On the Setup page, click Security.

c. On the Security Setup page, click Authentication Server.

Step 2 Use the 802.1x Protocol Version (for EAP authentication) drop-down menu to select the draft of the 802.1x protocol the access point radio should use. Menu options include:

Draft 7—No radio firmware versions compliant with Draft 7 have LEAP capability, so you should not need to select this setting.

Draft 8—Select this option if LEAP-enabled client devices that associate with this access point use radio firmware versions 4.13, 4.16, or 4.23.

802.1x-2001 (formerly Draft 10)—This is the default setting. Select this option if client devices that associate with this access point use Microsoft Windows XP EAP authentication or if LEAP-enabled client devices that associate with this access point use radio firmware version 4.25 or later.

Step 3 Click Apply or OK to apply the setting. The access point reboots.


Select WEP Key 1 as Transmit Key for EAP Authentication

If you use Network-EAP as the authentication type on your wireless network, you must select key 1 as the transmit key on the access point AP Radio Data Encryption page. The access point uses the WEP key you enter in key slot 1 to encrypt multicast and broadcast data signals that it sends to EAP-enabled client devices. Because the access point transmits the WEP key used for multicast messages to the EAP-enabled client device during the EAP authentication process, that key does not have to appear in the EAP-enabled device's WEP key list. The access point uses a dynamic WEP key to encrypt unicast messages to EAP-enabled clients. When you set up a repeater access point to authenticate as a LEAP client, the repeater derives a dynamic WEP key and uses it to communicate with the root access point. Repeaters not set up for LEAP authentication use static WEP keys when communicating with other access points.


Note If you do not use EAP authentication on your wireless network, you can select any WEP key as the transmit key. If you use EAP authentication and you enable broadcast key rotation, you can enable WEP without entering WEP keys.


MIB File Compatible with VxWorks Firmware Version 11.00 and Later

The access point MIB file (AWCVX-MIB) is supported only by access point VxWorks firmware version 11.00 and later. Earlier versions of firmware do not support this MIB. You can download the access point MIB at:

http://www.cisco.com/public/sw-center/sw-wireless.shtml.

Hot Standby Mode and Radio Diagnostics Availability

The hot standby feature is available on dual mode access points. To make the feature operational, both radios must be set to the hot standby mode.

The Carrier Test and Antenna Alignment radio diagnostics tool are available only for an access point's 2.4-GHz radio.

Important Notes

This section lists important information about access points running VxWorks firmware version 12.03T.

SQL Worm Virus Vulnerability

In certain situations, the access point could be affected by the SQL Worm virus. The signature of this worm appears as high volumes of UDP traffic to port 1434. Symptoms on Cisco devices include but are not limited to high CPU usage and traffic drops on the input interfaces.

The worm has been referenced by several names including Slammer, Sapphire, and MS SQL.

Cisco has prepared a security notice containing details about this virus and how to eliminate it. The document is on Cisco.com at the following link:

http://www.cisco.com/warp/public/707/cisco-sn-20030125-worm.shtml

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.

Adding or Deleting Proxy Mobile IP AAPs

If you need to add or delete proxy Mobile IP authoritative access points (AAPs), you must disable proxy Mobile IP before changing the configuration. Follow these steps.


Step 1 Browse to the Setup page.

Step 2 In the Services section, click Proxy Mobile IP. The Proxy Mobile IP Setup page appears.

Step 3 Click General. The Proxy Mobile IP General page appears.

Step 4 Change the Enable Proxy Mobile IP setting to no.

Step 5 Add or delete AAPs as necessary.

Step 6 Change the Enable Proxy Mobile IP setting to yes.


Error Message Appears for Access Points with One Radio

When you install VxWorks firmware version 12.03T in an access point with one radio, an error message appears. If your access point contains only the internal 2.4-GHz radio, this error message appears:

** Failed to Load Driver for device entry #3.

If your access point contains only the external 5-GHz radio, this error message appears:

** Failed to Load Driver for device entry #2.

You can ignore these messages. The errors do not appear if your access point contains two radios.

Installing a 5-Ghz Radio May Require Updating Firmware

If you upgrade a 2.4-GHz access point by adding a 5-GHz radio module, you must ensure that the firmware is updated prior to installing the radio, otherwise the access point fails to recognize the new radio. In order to install the 5-GHz radio module, the access point must be running VsWorks version 11.54T or later in a VxWorks-based access point or IOS Release 12.2(8)JA or later in an IOS-based access point.

Enabling Broadcast Key Rotation on One Radio Enables It on Both Radios

If you enable Broadcast Key Rotation on one of the radios in a dual-radio access point, Broadcast Key Rotation is automatically enabled on the other radio.

Set Flow Control to None or Xon/Xoff When Using Terminal Emulator

The terminal emulator flow control setting for 1200 series access points (none or Xon/Xoff) differs from the flow control setting for 340 and 350 series access points (none, Xon/Xoff, or Hardware).

To use a terminal emulator to open the 1200 series access point's command-line interface (CLI), use these settings for the terminal emulator connection:

9600 baud

8 data bits

No parity

1 stop bit

No flow control or Xon/Xoff

Reboot of Workgroup Bridges Required When Allowing More Than 20

With VxWorks firmware version 12.03T, you can select no for the Classify Workgroup Bridges as Network Infrastructure setting on the AP/Root Radio Advanced page to allow up to 20 workgroup bridges to associate to the access point. When you select no for this setting, you must reboot workgroup bridges associated to the access point.

The "Reliable multicast messages from the access point to workgroup bridges" setting limits reliable delivery of multicast messages to approximately 20 Cisco Aironet Workgroup Bridges that are associated to the access point. The default setting, disabled, reduces the reliability of multicast delivery to allow more workgroup bridges to associate to the access point.

Access points and bridges normally treat workgroup bridges not as client devices but as infrastructure devices, like access points or bridges. Treating a workgroup bridge as an infrastructure device means that the access point reliably delivers multicast packets, including Address Resolution Protocol (ARP) packets, to the workgroup bridge.

The performance cost of reliable multicast delivery—duplication of each multicast packet sent to each workgroup bridge—limits the number of infrastructure devices, including workgroup bridges, that can associate to the access point. To increase beyond 20 the number of workgroup bridges that can maintain a radio link to the access point, the access point must reduce the delivery reliability of multicast packets to workgroup bridges. With reduced reliability, the access point cannot confirm whether multicast packets reach the intended workgroup bridge, so workgroup bridges at the edge of the access point's coverage area might lose IP connectivity. When you treat workgroup bridges as client devices, you increase performance but reduce reliability.

Cisco Discovery Protocol Re-Enabled for Individual Interfaces on Reboot

The Cisco Discovery Protocol (CDP) feature is enabled by default, and CDP is enabled for each of the access point's relevant interfaces by default. However, if you disable CDP for one of the individual interfaces, the access point re-enables CDP for that interface when it reboots. If you disable CDP completely, the access point does not re-enable CDP on reboot.

Symbol IP Phone Issues

When a Symbol IP phone is associated to a VoIP VLAN (Symbol extensions enabled), the phone associates to the access point and is authenticated approximately every 2 seconds. the Symbol phone shows a "No Network" error every 1 to 2 minutes. It also appears that Symbol phones do not work well when using a non-primary SSID. It is possible that the phone does not perform an active probe and therefore does not detect information about the SSID it associated with in the beacon, causing it to reassociate and authenticate.

Symbol phones may disconnect and be unable to roam between subnets when the access point passes multicast or FTP traffic. If there are no FTP or multicast sessions in progress the Symbol phone operates normally and is able to roam between subnets. To work around this issue, limit multicast and FTP traffic if you are using Symbol IP phones in a proxy Mobile IP environment.

Caveats

This section lists resolved and open software issues in VxWorks firmware version 12.03T.

Getting Bug Information on Cisco.com

If you are a registered Cisco user, you can use the Cisco TAC Software Bug Toolkit, which consists of three tools (Bug Navigator, Bug Watcher, and Search by Bug ID Number) that help you identify existing bugs (or caveats) in Cisco software products.

Access the TAC Software Bug Toolkit at:

http://www.cisco.com/support/bugtools/.

Open Caveats

The following caveats have not been resolved for VxWorks firmware version 12.03T:

CSCdz30285—The Configuring the Cisco Wireless Security Suite application note is incorrect.

The screen capture in section 3.1 of this document shows Add AAA Server, which is incorrect as the Aironet device is a client of the ACS, not a server.

Workaround: Call the TAC for setup instructions.

CSCdy49857—VxWorks event descriptions in documentation are incomplete.

Events displayed on the Event Log page are not described in the software configuration guides for 350 and 1200 series devices.

CSCea47390—Access point crashes on task 0x97d2d8 "tThttpd."

Cisco has been unable to reproduce this caveat and is investigating.

CSCea66593—Access point reboots sporadically because of a protection violation in tRcv_awc0.

Reboots can occur within a 2 to 3 hour period or remain on line for several days and occur based on a protection violation of data accessed associated with task tRcv_awc0.

There is no workaround for this caveat.

CSCin46049—Client is always forced to EAP-associate with multiple VLANs.

When multiple VLANs with different encryption schemes are configured on an access point, the client is forced to authenticate using EAP-TLS. The access point's association table shows that the client is associated to the correct VLAN but shows it as EAP associated.

CSCin46604—The Solicitations Sent counter on the authoritative access point is always incremented by 2 instead of 1.

CSCin46620—Resetting All System Factory Defaults does not delete existing VLAN numbers.

When the access point is reset to factory defaults, any VLANs created remain in the Existing VLAN box and with the VLAN name No Name.

CSCin46639—Access point does not switch to repeater mode when Ethernet link is down.

When the Ethernet interface is shut down through a console command, the access point does not switch to repeater mode. However, when the Ethernet cable is unplugged, the access point switches to repeater mode after the default timeout of 2 seconds.

CSCin45850—A valid access point is not reporting a rogue access point in its logs when an invalid RADIUS server IP address is used in the rogue AP.

CSCin46851—After roaming from its home network to the foreign network, the mobile node fails to reach the home or foreign agent but associates to the authoritative access point on the foreign network. The mobile node must fully reathenticate to reach the entire network.

Resolved Caveats

The following caveats are resolved in VxWorks firmware version 12.03T:

CSCdx81372—The access point accepts VxWorks version 11.56-generated ini file.

CSCdy10787—The access point no longer aborts configurations containing an unknown MIB variable.

CSCdy80821—The access point no longer continuously reboots after applying a configuration template.

CSCdz00540—Share authentication now works when TKIP is enabled.

CSCdz23591—The access point no longer stops sending multicast packets, thereby eliminating configuration distribution problems.

CSCdz24966—Broadcast key rotation operates correctly with current 350 client.

CSCdz32270—DHCP client ID and channel information is no longer distributed to all access points.

CSCdz34132—Aironet Client Utility (ACU) now displays IP address with EAP-TLS instead of MAC address.

CSCdz38726—Eliminated possible confusion for exiting console.

CSCdz41180—The Clear Alert Statistics button in the Event Handling Setup page is correctly documented.

CSCdz47442—IP Setup Utility (IPSU) returns incorrect IP addresses in large networks.

This caveat is closed. Based on testing, the problem occurs only with old VxWorks or IOS software releases. If a network has mixed access points with old and new software releases, the problem may exist. Upgrading all access points to a new software release eliminates the problem.

CSCdz48575—The access point now defaults to No Action on loss of Ethernet.

CSCdz49470—The access point no longer sends a DNS not available error.

CSCdz55839—DHCP no longer fails after first broadcast WEP key rotation.

CSCdz68197—The 802.11a radio no longer fails when rebooted.

CSCdz71408—The radio returns to an operational state after being shut down.

CSCea09515—VxWorks access points now provide three EAP retries.

CSCea17203—Memory leak issue when sending an LLC packet is resolved.

CSCea21135—RADIUS-based VLAN clients are now able to communicate to clients on the same VLAN.

CSCea36554—Access point no longer reboots on large file transfers.

CSCea41867—Quality of Service for Policy Group parameter now works regardless of QBSS setting.

CSCea45758—Documentation describing EAP authentication has been amplified and corrected.

CSCea45776—Documentation describing dual radio operation in repeater mode has been amplified.

CSCea66109—Access points with MAC authentication set no longer drop packets when a client roams.

CSCeb18758—Documentation now provides better explanation of workgroup bridge limitation in network infrastructure mode.

See the "Reboot of Workgroup Bridges Required When Allowing More Than 20" section for more information.

CSCin18914—IP release or renew now occurs with EAP-TLS+MIC+KH+BWR.

CSCin46076—Client now gets DHCP IP address with EAP-MD5 and VLAN.

Other Caveats

The following is a status of caveats published in the release notes for previous VxWorks versions that were not resolved in version 12.03T:

CSCdz04380—Incorrect values are advertised for CWMin and CWMax on Voice VLAN.

This caveat is postponed. The issue is to be resolved in a future maintenance release for VxWorks access points and will advertise the CWMin and CWMax values as defined by IEEE 802.11e.

CSCdy11906—When WEP is enabled and you set all WEP keys to not set, WEP is still enabled but the web-browser page indicates that WEP is disabled.

This caveat is closed. Disable encryption by changing the WEP setting instead of removing the key.

CSCdy20169—The access point sometimes displays a warning message when booted.

This caveat is a duplicate of CSCdy72691, which was resolved in an early version.

CSCdy27831—Access point must be rebooted after setting Ethernet Unicast Filter to disallowed.

This caveat is closed.

CSCdy29556—Symbol IP phone continuously associates and authenticates to an access point configured with multiple VLANs.

This caveat is closed. See "Symbol IP Phone Issues" section for additional information.

CSCea39261—SQL Worm virus vulnerability affects access point.

Follow the instructions in the Cisco Security Notice at this link to reduce your vulnerability:

http://www.cisco.com/warp/public/707/cisco-sn-20030125-worm.shtml

Follow the instructions in the "SQL Worm Virus Vulnerability" section.

CSCdz43069—Symbol phone not working when multicast or FTP traffic is passed.

This caveat is closed. See "Symbol IP Phone Issues" section for additional information.

CSCdy73695—An error is displayed when a repeater access point receives packets from a root access point while attempting to associate.

This caveat is closed due to lack of severity.

CSCdy76093—Proxy Mobile IP with multiple authoritative access points continuously sends update packets.

This caveat is closed.

CSCdx35804—RADIUS attributes in documentation is incomplete or inaccurate.

This caveat is being investigated.

CSCdw89705—All Ethernet devices behind a client bridge show up as roamed.

This caveat is closed. No further action is planned.

CSCea49176—PEAP requires users to change password results in failed logon.

Cisco has been unable to reproduce this caveat.

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The type of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.

We categorize Cisco TAC inquiries according to urgency:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration. There is little or no impact to your business operations.

Priority level 3 (P3)—Operational performance of the network is impaired, but most business operations remain functional. You and Cisco are willing to commit resources during normal business hours to restore service to satisfactory levels.

Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively impacted by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority level 1 (P1)—An existing network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Cisco TAC Website

The Cisco TAC website provides online documents and tools to help troubleshoot and resolve technical issues with Cisco products and technologies. To access the Cisco TAC website, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website require a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

http://tools.cisco.com/RPF/register/register.do

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC website, you can open a case online at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases online so that you can fully describe the situation and attach any necessary files.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.
