Important Information for Controller-Based Deployments
Keep these guidelines in mind when you use Cisco CW9166I APs:
• The AP can only communicate with Cisco wireless controllers.
• The AP does not support Wireless Domain Services (WDS) and cannot communicate with WDS devices.
• CAPWAP does not support Layer 2. The AP must get an IP address and discover the controller using
• The AP console port is enabled for monitoring and debug purposes.
• All the configuration commands are disabled when the AP is connected to a controller.
Configuring 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.
The following is a DHCP Option 43 configuration example on a Windows 2003 Enterprise DHCP server for
use with Cisco Catalyst lightweight access points. For other DHCP server implementations, see the product
documentation for configuring DHCP Option 43. In Option 43, you should use the IP address of the controller
management interface.
configuration on the controller has been changed using the syslog host <ip address> command. In this
case, the controller sends the new global syslog server IP address to the access point.
To configure the global syslog server IP address, run these commands:
1. configure terminal
2. ap profile ap-profile-name
3. syslog host syslog IP address
4. exit

is erased from persistent storage, and the new address is stored in its place. The access point also starts
sending all the syslog messages to the new IP address, provided the access point can reach the syslog
server IP address.
You can configure the syslog server for access points and view the access point join information only from
the controller CLI.
However, the controller provides functionality equivalent to WDS when the AP joins it.
