Troubleshooting Autonomous Access Points

This chapter provides troubleshooting procedures for basic problems with the autonomous access point (model: AIR-AP1131AG or AIR-AP1131G). For the most up-to-date, detailed troubleshooting information, refer torefer to the Cisco Technical Support and Documentation website at the following URL:

Checking the Autonomous Access Point LEDs

If your autonomous access point is not working properly, check the Status LED on the top panel or the Ethernet and Radio LEDs in the cable bay area. You can use the LED indications to quickly assess the unit's status. Figure 3-1 shows the access point LEDs (for additional information refer to the Event Log using the access point browser interface).

1	Status LED	3	Ethernet LED
2	Access point cover	4	Radio LED

Note When the access point cover is opened, the Status LED colors are not visible.

Note There can be slight color variations in the Status LED of each access point.

Checking Basic Settings

Mismatched basic settings are the most common causes of lost connectivity with wireless clients. If the access point does not communicate with client devices, check the following areas.

Default IP Address Behavior

When you connect an 1130AG access point running Cisco IOS Release 12.3(2)JA or later software with a default configuration to your LAN, the access point requests an IP address from your DHCP server, and if it does not receive an IP address, it continues to send requests indefinitely.

Default SSID and Radio Behavior

In Cisco IOS Relese 12.3(2)JA2 and earlier, the access point radios are enabled by default and the default SSIDs are tsunami.

In Cisco IOS Release 12.3(4)JA and later, the access point radios are disabled by default, and there are no default SSIDs. You must create an SSID and enable the radio before the access point will allow wireless associations from other devices. These changes to the default configuration improve the security of newly installed access points. Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points for instructions on configuring the SSID and the "Enable Radio Interfaces" section for instructions on enabling the radio interfaces.

Enable Radio Interfaces

Step 2

When the Summary Status page displays, click Network Interfaces > Radio0-802.11B or Radio0-802.11G and the radio status page displays.

Step 6

Click Network Interfaces > Radio0-802.11A and the radio status page displays.

SSID

Wireless clients attempting to associate with the access point must use the same SSID as the access point. If a client device's SSID does not match the SSID of an access point in radio range, the client device will not associate. The access point default SSID is tsunami. Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points for instructions on how to configure an SSID.

Note The default SSID (tsunami) is not supported in access points running Cisco IOS Release 12.3(4)JA or later. You must configure an SSID before client devices can associate to the access point.

WEP Keys

The WEP key you use to transmit data must be set up exactly the same on your access point and any wireless devices with which it associates. For example, if you set WEP Key 3 on your client adapter to 0987654321 and select it as the transmit key, you must also set WEP Key 3 on the access point to exactly the same value. The access point does not need to use Key 3 as its transmit key, however.

Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points for instructions on setting the access point's WEP keys.

Security Settings

Wireless clients attempting to authenticate with your access point must support the same security options configured in the access point, such as EAP or LEAP, MAC address authentication, Message Integrity Check (MIC), WEP key hashing, and 802.1X protocol versions.

If a wireless client is unable to authenticate with your access point, contact the system administrator for proper security settings in the client adapter and for the client adapter driver and firmware versions that are compatible with the access point settings.

Note 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.

Low Power Condition for Autonomous Access Points

Warning This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source or an IEC60950 compliant limited power source. Statement 353

The access point can be powered from the 48-VDC power module or from an in-line power source. The access point supports the IEEE 802.3af power standard, Cisco Pre-Standard PoE protocol, and Cisco Intelligent Power Management for in-line power sources.

For full operation, the access point requires 12.95 W of power. The power module and Cisco Aironet power injectors are capable of supplying the required power for full operation, but some inline power sources are not capable of supplying 12.95 W. Also, some high-power inline power sources, might not be able to provide 12.95 W of power to all ports at the same time.

Note An 802.3af compliant switch (Cisco or non-Cisco) is capable of supplying sufficient power for full operation.

Note If your access point is connected to in-line power, do not connect the power module to the access point. Using two power sources on the access point might cause the access point to shut down to protect internal components and might cause the switch to shut down the port to which the access point is connected. If your access point shuts down, you must remove all power and reconnect only a single power source.

On power up, the access point is placed into low power mode (both radios are disabled), Cisco IOS software loads and runs, and power negotiation determines if sufficient power is available. If there is sufficient power then the radios are turned on; otherwise, the access point remains in low power mode with the radios disabled to prevent a possible over-current condition. In low power mode, the access point activates the Status LED low power error indication, displays a low power message on the browser and serial interfaces, and creates an event log entry (see the "Checking the Autonomous Access Point LEDs" section and "Inline Power Status Messages" section).

Intelligent Power Management

The access point requires 12.95 W of power for full power operation with both radios, but only needs 6.3 W of power when operating in low power mode with both radios disabled. To help avoid an over-current condition with low power sources and to optimize power usage on Cisco switches, Cisco developed Intelligent Power Management, which uses Cisco Discovery Protocol (CDP) to allow powered devices (such as your access point) to negotiate with a Cisco switch for sufficient power.

The access point supports Intelligent Power Management and as a result of the power negotiations, the access point will either enter full power mode or remain in low power mode with the radios disabled.

Note Independent of the power negotiations, the access point hardware also uses the 802.3af classification scheme to indicate the power required from the power source. However, the power source cannot report the power available to the access point unless the power source also supports Intelligent Power Management.

Some Cisco switches that are capable of supplying sufficient power require a software upgrade to support Intelligent Power Management. If the software upgrade is not desired, you can configure the access point to operate in pre-standard compatibility mode and the access point automatically enters full power mode if these Cisco switches are detected in the received CDP ID field.

Tip

If your switch is capable of supplying sufficient power for full operation but the access point remains in low-power mode, your access point or your switch (or both) might be misconfigured (see Table 3-2 and Table 3-3).

If your inline power source is not able to supply sufficient power for full operation, you should consider these options:

Inline Power Status Messages

These messages are logged on the console port by the access point to report the power condition:

•

%CDP_PD-4-POWER_OK: Full Power - AC_ADAPTOR inline power source—This message indicates the access point is using the power module and can support full-power operation.

•

Note

You need to upgrade the software on the Cisco switch to support Intelligent Power Management or configure the access point for pre-standard compatibility.

•

%CDP_PD-4-POWER_OK: Full power - INJECTOR_CONFIGURED_OVERRIDE_SAFETY inline power source —This message indicates the access point has been configured to override the inline power checks and a power injector is installed.

Configuring Power Using the CLI

Intelligent Power Management support is dependent on the version of software resident in the Cisco switch that is providing power to the access point. Each Cisco switch should be upgraded to support Intelligent Power Management. Until the software is upgraded, you can configure the access point to operate with older Cisco switch software using the following Cisco IOS CLI command:

Note The power inline negotiation injector installed command will fail if CDP is disabled.

When using the p;ower inline negotiation injector override command, you must use a power injector to prevent possiblly overloading underpowered power sources.

You can use this Cisco IOS CLI command to inform the access point of the following:

•

The Cisco switch does not support Intelligent Power Management but should be able to supply sufficient power.

•

A power injector is being used to supply sufficient power and the Cisco switch does not support Intelligent Power Management.

•

The access point was moved to a new Cisco switch port and a power injector is being used to supply sufficient power.

Note After completing your configuration changes, you must remove the serial console cable from the access point.

Refer to Table 3-2 for information on when to use this special Cisco IOS command and the corresponding Cisco switch power command.

Table 3-2 Using Cisco IOS Commands

Running the Carrier Busy Test

You can use the carrier busy test to determine the least conjested channel for a radio interface (802.11g or 802.11a). You should typically run the test several times over several days to obtain the best results and to avoid temporary activity spikes.

Note The carrier busy test is primarily used for single access points or bridge environments. For sites with multiple access points, a site survey is typically performed to determine the best operation location and operating frequency for the access points.

Note All associated clients on the selected radio are deassociated during the 6 to 8 seconds needed for the carrier busy test.

Step 2

Click Network Interfaces and the Network Interface Summary screen appears.

Step 3

Choose the radio interface experiencing problems by clicking Radio0-802.11G or Radio1-802.11A. The respective radio status page appears.

Step 4

Click the Carrier Busy Test tab and the Carrier Busy Test screen appears

When the test completes, the results are displayed on the screen. For each of the channel center frequencies, the test produces a value indicating the percentage of time that the channel is busy.

Running the Ping Test

You can use the ping test to evaluate the link to and from an associated wireless device. The ping test provides two modes of operation:

Performs a test using a specified number of packets and then displays the test results.

Performs a test that continuously operates until you stop the test and then displays the test results.

Step 3

Click the MAC address of an associated wireless device and the Statistics page for that device appears.

Step 5

If you want to specify the number of packets to use in the test, follow these steps:

When the test has completed, the test results are displayed at the bottom of the page. You should check for any lost packets that can indicate a problem with the wireless link. For best results, you should also perform this test several times.

Resetting to the Default Configuration

If you forget the password that allows you to configure the access point, you may need to completely reset the configuration. You can use the MODE button on the access point or the web-browser interface.

Note The following steps reset all configuration settings to factory defaults, including passwords, WEP keys, the IP address, and the SSID.
