Troubleshooting

If you experience difficulty getting your access point installed and running, look for a solution to your

problem in this guide or in additional access point documentation. These, and other documents, are

available on Cisco.com.

Guidelines for Using Cisco Aironet Lightweight Access Points

Keep these guidelines in mind when you use 3500 series lightweight access points:

• The access point can only communicate with Cisco wireless LAN controllers, such as 2100, 4400,

and 5500 series controllers.

• The access point does not support Wireless Domain Services (WDS) and cannot communicate with

WDS devices. However, the controller provides functionality equivalent to WDS when the access

point joins it.

• CAPWAP does not support Layer 2. The access point must get an IP address and discover the

controller using Layer 3, DHCP, DNS, or IP subnet broadcast.

• The access point console port is enabled for monitoring and debug purposes. All configuration

commands are disabled when the access point is connected to a controller.

Using DHCP Option 43

You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling

them to find and join a controller. For additional information, refer to the "Configuring DHCP Option

43 and DHCP Option 60" section on page 30.

Checking the Access Point LED

Figure 4 shows the location of the access point Status LED.

Regarding LED status colors, it is expected that there will be small variations in color intensity

and hue from unit to unit. This is within the normal range of the LED manufacturer's

specifications and is not a defect.
