Guidelines for Using the Access Points

Guidelines for Using the Access Points

You should keep these guidelines in mind when you use the access points:

•The access points can only communicate with controllers and cannot operate independently.

•The access points do not support Wireless Domain Services (WDS). The access points cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when the access point associates to it.

•The access points support Layer 2 or Layer 3 LWAPP communications with the controllers. In Layer 2 operation, the access point and the controller must be on the same subnet and communicate with each other using MAC addresses in encapsulated Ethernet frames. This operation is not scalable to larger networks and not recommended by Cisco.

In Layer 3 operation, the access point and the controller can be on the same or different subnets. Layer 3 operation is scalable and is recommended by Cisco. A Layer 3 access point on a different subnet than the controller requires a DHCP server on the access point subnet and a route to the controller. The route to the controller must have destination UDP ports 12222 and 12223 open for LWAPP communications. The route to the primary, secondary, and tertiary controllers must allow IP packet fragments.

•Before deploying your access points ensure that the following has been done:

–Your controllers are connected to switch ports that are configured as trunk ports

–Your access points are connected to switch ports that are configured as untagged access ports

–A DHCP server is reachable by your access points and has been configured with Option 43. Option 43 is used to provide the IP addresses of the Management Interface of your controllers. Typically, a DHCP server can be configured on a Cisco switch.

–Optionally a DNS server can be configured to enable CISCO-LWAPP-CONTROLLER.<local domain> to resolve to the IP addresses of the Management Interface of your controllers.

–Your controllers are configured and reachable by the access points

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 DHCP Option 43” section on page F-1.
