Before deploying your access points to their final locations, follow these steps to prime your access
points:
In a Layer 2 environment, where the access points are located on the same subnet as the controller, the
Step 1
access point communicates directly with the controller.
In a Layer 3 environment, ensure a DHCP server (typically on your switch) is enabled on the same subnet
Step 2
as your access points. The access points will receive its IP address and controller information using
DHCP Option 43.
The access point must be able to find the IP address of the controller. This can be accomplished using
DHCP, DNS, OTAP, or IP subnet broadcast. This guide describes the DHCP method to convey the
controller IP address. For other methods, refer to the product documentation. See also the
DHCP Option 43 for Lightweight Access Points" section on page G-1
Note
Ensure that your controller is connected to a switch trunk port.
Step 3
Configure the controller in LWAPP Layer 3 mode and ensure its DS Port is connected to the switch. Use
Step 4
the CLI, web-browser interface, or Cisco WCS procedures as described in the appropriate controller
guide.
In multi-controller environments, You can set one controller's DS port to Master (you can use the
a.
config network master-base disable CLI command or you can use the controller GUI) so that new
access points always associate with it. You can use the show network config CLI command to
determine if the controller DS port is the master.
All access points associate to the master controller. From one location, you can configure access
point settings, such as primary, secondary, and tertiary controllers. This allows you to redistribute
your access points to other controllers on the network.
You can also use a Cisco WCS server to control, configure, and redistribute all your access points
from a single location.
Step 5 Apply power to the access points:
a. Connect your access points to untagged access ports on your POE capable switch. You can
optionally use power modules or power injectors to power your access points.
b. After you power up the access point, it begins a power-up sequence that you can check by observing
the access point LEDs. All LEDs blink sequentially back and forth, indicating that the access point
is trying to find a controller.
Note
If the access point shuts down (all LEDs off), check to ensure that sufficient power is available.
c.
When the access point associates with the controller, if the access point code version differs from
d.
the controller code version, the access point downloads the operating system code from the
controller. All the access point LEDs blink simultaneously during the download.

F-2
For a Layer 3 access point on a different subnet than the controller, ensure ensure the route to
the controller has destination UDP ports 12222 and 12223 open for LWAPP communications.
Ensure that the routes to the primary, secondary, and tertiary controllers allow IP packet
fragments.
If the access point remains in this mode for more than 5 minutes, the access point is unable
to find the master controller. Check the connection between the access point and the
controller and ensure they are on the same subnet.
