Guidelines for Using Cisco Aironet Lightweight Access Points
Keep these guidelines in mind when you use a 1140 series lightweight access point:
• The access point can only communicate with Cisco controllers, such as the 2106 series wireless
LAN controllers or 4400 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 associates to it.
• CAPWAP does not support Layer 2. The access point must get an IP address and discover the
controller using DHCP, DNS, or IP subnet broadcast.
• The access point console port is enabled for monitoring and debug purposes (all configuration
commands are disabled when 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
the access point to find and join a controller. For additional information, refer to the
“Configuring
Option 43” section on page 22.
Checking the Lightweight Access Point LEDs
If your lightweight access point is not working properly, check the Status, Ethernet, and Radio LEDs.
You can use the LED indications to quickly assess the unit’s status.
Figure 3 shows the location of the
access point LEDs.
