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
• The access point is disconnected from the controller and joins another controller. In this case, the new
controller sends its global syslog server IP address to the access point.
• Whenever a new syslog server IP address overrides the existing syslog server IP address, the old address
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.
Note
Important Information for Controller-based Deployments
Keep these guidelines in mind when you use the AP:
• The AP can only communicate with Cisco controllers.
• The AP does not support Wireless Domain Services (WDS) and cannot communicate with WDS devices.
However, the controller provides functionality equivalent to WDS when the AP joins it.
• CAPWAP does not support Layer 2. The AP must get an IP address and discover the controller using
Layer 3, DHCP, DNS, or IP subnet broadcast.
• The AP console port is enabled for monitoring and debugging purposes. All 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 AP, enabling it to find and
join a controller.
The following is a DHCP Option 43 configuration example on a Microsoft Windows 2003 Enterprise DHCP
server for Cisco Catalyst lightweight APs. For other DHCP server implementations, consult the product
documentation to configure DHCP Option 43. In Option 43, use the IP address of the controller management
interface.
