Note For a Layer 3 access point on a different subnet than the controller, ensure that the

access point subnet has a DHCP server and a route to the controller. Also ensure that

the route to the controller has destination UDP ports 12222 and 12223 open for

LWAPP communications and that the routes to the primary, secondary, and tertiary

controllers allow IP packet fragments.

Step 2 Verify that your controller is connected to a switch trunk port.

Step 3 Configure the controller in LWAPP Layer 3 mode and ensure that its DS port is connected to

the switch. Use the CLI, web-browser interface, or Cisco WCS procedures as described in the

appropriate controller guide.

a. Make sure that access point ports are available through the controller management or

AP-manager interfaces.

b. Set the controller DS port as master (you can use the config network master-base disable CLI

command) so that new access points always associate with it. Use the show network

config CLI command to determine if the controller DS port is the master.

Step 4 Apply power to the access points:

a. Connect your access points to untagged access ports on your POE-capable switch or to the

access point power module (AIR-PWR-1000=).

b. After you power up the access point, it begins a power-up sequence that you can check by

observing the access point LEDs. The red Alarm LED turns on for approximately 15 to 20

seconds and then all LEDs blink sequentially, indicating that the access point is trying to find

the master controller.

If the access point remains in this mode for more than 5 minutes, it is unable to find the

master controller. Check the connection between the access point and the controller and

make sure that they are both on the same subnet.

If the access point shuts down (Power LED off), verify that power is available.

c. After the access point finds the master controller, the access point compares its operating

system version cod with that running on the controller. If the version is not the same, the

access point downloads the controller’s version. While the download is in progress, the access

point LEDs blink simultaneously.

Step 5 When the operating system is successfully downloaded, the access point reboots. Normal

operation is indicated when the Alarm LED is off, the Power LED is green, and the 2.4-GHz

and 5-GHz LEDs blink indicating radio activity.

If the Alarm LED remains red for more than a minute, remove power from the access point

and contact Cisco Technical Support for assistance.

Step 6 Use the controller CLI, controller GUI, or Cisco WCS to configure the access points with

primary, secondary, and tertiary controller names.
